Description

Automatic anchor withdrawing device for anchor cable

Technical Field

The invention relates to the technical field of mine support engineering, in particular to an automatic anchor withdrawing device for an anchor rope.

Background

At present, the anchor rope anchor removing machine is widely used in scenes such as mines, wild cliffs and the like, but the existing anchor rope anchor removing machine has some inconveniences when being applied. Such as:

(1) The reliability is not high; specifically, when the anchor is removed, a worker needs to judge whether the separation process of the anchor ring and the anchor plug needs to be continuously pressurized or not by virtue of working experience; if the pressure is too small, the anchor plug is difficult to take out; if the pressure is too high, the anchor cable is possibly pulled out;

(2) The efficiency is low, and the labor force requirement is high; specifically, when the anchor cable is withdrawn from the roadway, one worker firstly takes the anchor withdrawing jack to the top plate of the roadway to be connected with the anchor cable, and then another worker waits for the anchor plug to be separated from the anchor ring and takes out the anchor plug by using a tool. Because of the height of the roadway, a worker is required to support the ladder. Therefore, the whole anchor removing operation needs to be completed by at least three workers; occupies labor force, increases the production cost of coal mine enterprises, and reduces the benefit.

(3) Has certain danger; specifically, anchor withdrawing operation requires manual anchor plug taking by a worker, in addition, in the whole anchor withdrawing and pressurizing process, the worker needs to repeatedly climb a ladder to judge whether to continue pressurizing, and the anchor is required to be taken down after anchor withdrawing, so that the repeated climbing of the ladder can also threaten the personal safety of the worker.

(4) Complicated operation, low success rate and long time consumption, and particularly when a tunnel tray is deformed, an anchor cable is forked and the like, the anchor withdrawing operation is more difficult;

notably, (5) when the anchor cable is locked, the anchor plug penetrates into the anchor ring, so that the clamping groove on the outer wall of the anchor plug is hidden in the anchor ring or a small part of the clamping groove is exposed out of the anchor ring, and therefore, the anchor withdrawing component cannot complete anchor withdrawing operation through the clamping groove during anchor withdrawing operation.

Specifically, in the initial stage, based on the clutch mechanism 15, the power transmission between the power mechanism and the secondary anchor-withdrawing mechanism 14 is disconnected; so in the anchor withdrawing operation process, the power mechanism drives the primary anchor withdrawing mechanism 13 to move the anchor plug 19 out of the anchor ring 17 so as to expose the clamping groove 171 arranged on the anchor plug 19; then, under the driving action of the power mechanism, the clutch mechanism 15 connects the power connection between the power mechanism and the secondary anchor-withdrawing mechanism 14, namely: the power mechanism can transmit power to the secondary anchor withdrawing mechanism 14, so that the power mechanism drives the secondary anchor withdrawing mechanism 14 to be clamped in the clamping groove 171 and drag the anchor plug 19 to be separated from the anchor ring 17, thereby completing anchor withdrawing operation.

Specifically, in another embodiment, the number of the power mechanisms may be set to be plural, such as: the power mechanism is configured to include two structures, such as: the primary power structure 11 and the secondary power structure, wherein the primary power structure 11 is connected to the primary anchor withdrawing mechanism 13 and the secondary anchor withdrawing mechanism 14, the clutch mechanism 15 is arranged between the primary power structure 11 and the secondary anchor withdrawing mechanism 14, the primary power structure 11 is used for driving the primary anchor withdrawing mechanism 13 to move the anchor plug 19 out of the anchor ring 17 so as to expose a clamping groove 171 arranged on the anchor plug 19, and the primary power structure 11 drives the secondary anchor withdrawing mechanism 14 to clamp the clamping groove 171 under the condition that the clutch mechanism 15 transmits the power output by the primary power structure 11 to the secondary anchor withdrawing mechanism 14; and the secondary power structure is connected to the secondary anchor withdrawing mechanism 14, and when the primary power structure 11 drives the secondary anchor withdrawing mechanism 14 to be clamped with the clamping groove 171, the secondary power structure drives the secondary anchor withdrawing mechanism 14 to drag the anchor plug 19 to be separated from the anchor ring 17.

Of course, in this embodiment, the primary power structure 11 and the secondary power structure are not limited, and only the primary anchor removing mechanism 13 and the secondary anchor removing mechanism 14 can be driven to complete the anchor removing operation and power is provided for the primary power structure and the secondary power structure, for example: the primary power structure 11 and the secondary power structure may each be configured as one or more of the following: a motor, a cylinder, a hydraulic cylinder or a spring return mechanism.

It is noted that in another embodiment, the primary power structure is provided as a hydraulic cylinder, and the hydraulic cylinder includes: a cylinder 111, a piston 112 is arranged in the cylinder 111, one end of the piston 112 extends out of the cylinder 111, the piston 112 is movably connected with the cylinder 111, the piston 112 divides an oil cavity in the cylinder 111 into a reset oil cavity 113 and an anchor withdrawing oil cavity 114, and one end of the piston 112 penetrates through a cavity wall of the reset oil cavity 113 and extends out of the cylinder 111; the cylinder 111 is provided with a return oil hole 116 communicating with the return oil chamber 113 and an anchor return oil hole 115 communicating with the anchor return oil chamber 114, and the anchor return oil chamber 114 and the return oil chamber 113 are filled with oil through the anchor return oil hole 115 and the return oil hole 116, respectively, so that the pressure difference between the return oil chamber 113 and the anchor return oil chamber 114 is changed.

An anchor seat 161 and a primary anchor removing mechanism 13 are provided on the left side of the cylinder 111; wherein the anchor seat 161 is fixed to the end of the piston 112 extending out of the cylinder 111; therefore, in the case where oil is injected into the relief oil chamber 114 through the relief oil injection hole 115 and/or oil is injected into the return oil chamber 113 through the return oil injection hole 116 such that there is a pressure difference between the return oil chamber 113 and the relief oil chamber 114, the cylinder 111 moves as a mover to output power, while the piston 112 remains stationary with respect to the anchor seat 161 as a stator due to being fixed to the anchor seat 161; the power output end of the primary power structure 11 is the power output end of the cylinder 111 as a mover, and the anchor seat 161 is described in detail below for avoiding redundant description.

Specifically, under the action of the primary power structure 11, the anchor plug 19 is moved out of the anchor ring 17 through the primary anchor withdrawing mechanism 13 to expose the clamping groove 171 arranged on the anchor plug 19, and before that, the power transmission between the primary power structure 11 and the secondary anchor withdrawing mechanism 14 is disconnected based on the clutch mechanism 15; therefore, under the driving action of the primary power structure 11, the clutch mechanism 15 is connected with the power transmission between the primary power structure 11 and the secondary anchor withdrawing mechanism 14, in this case, the primary power structure 11 drives the secondary anchor withdrawing mechanism 14 to be clamped with the clamping groove 171, and the secondary power structure drives the secondary anchor withdrawing mechanism 14 to drag the anchor plug 19 to be separated from the anchor ring 17, so that anchor withdrawing operation is automatically completed, manual anchor plug taking is not needed, the operation intensity is reduced, complicated manual anchor withdrawing operation is not needed, anchor withdrawing operation is simplified, and certainly, anchor withdrawing operation is not completed by matching of multiple persons, so that the production cost of enterprises is saved, and the production benefit and the safety in the anchor withdrawing operation process are improved; in addition, the primary anchor withdrawing mechanism 13 can enable the anchor plug 19 to be exposed out of the clamping groove 171 on the outer wall, so that the secondary anchor withdrawing mechanism 14 can be smoothly and efficiently clamped with the clamping groove 171 to complete anchor withdrawing operation.

Further, in another embodiment, the primary anchor-withdrawing mechanism 13 referred to in the above embodiment is provided with the following arrangement:

specifically, the primary anchor removing mechanism 13 includes: the anchor-withdrawing locking ring 132 and the anchor-withdrawing fixing ring 131.

Wherein, the anchor withdrawing locking ring 132 is sleeved on the periphery of the anchor cable 18; the anchor-withdrawing fixing ring 131 is fixed at the power output end of the primary power structure 11, the anchor-withdrawing fixing ring 131 is sleeved on the outer wall of the anchor-withdrawing locking ring 132, and the abutting surface between the anchor-withdrawing locking ring 132 and the anchor-withdrawing fixing ring 131 is obliquely arranged (the anchor-withdrawing locking ring 132 and the anchor-withdrawing fixing ring 131 are in axial conical surface contact); the primary power structure 11 can drive the anchor-withdrawing fixed ring 131 to move back and forth along the length direction of the anchor cable 18, so that the anchor-withdrawing fixed ring 131 drives the anchor-withdrawing fixed ring 132 to lock the anchor cable 18 or release the anchor cable 18, and the anchor-withdrawing fixed ring 131, the anchor-withdrawing fixed ring 132 and the anchor cable 18 are linked under the condition that the anchor-withdrawing fixed ring 131 locks the anchor cable 18.

Of course, in another embodiment, the following settings may also be made: the primary anchor removing mechanism 13 includes only the anchor removing locking ring 132, and the anchor removing locking ring 131 is included in the primary power structure 11.

Specifically, the anchor fixing ring 131 and the anchor locking ring 132 are set to be tapered cylinders, the anchor locking ring 132 is sleeved on the outer periphery of the anchor cable 18, the anchor fixing ring 131 is sleeved on the outer periphery of the anchor locking ring 132, and the contact surface between the anchor fixing ring 131 and the anchor locking ring 132 is set to be inclined (the tapered surfaces between the anchor fixing ring 131 and the anchor locking ring 132 are in contact), for example: the anchor-withdrawing locking ring 132 is tapered along the axis direction thereof, the inner cavity of the anchor-withdrawing fixing ring 131 is tapered along the axis direction thereof, and the large-caliber opening and the small-caliber opening in the anchor-withdrawing fixing ring 131 are respectively positioned on the same side as the small-caliber opening and the large-caliber opening of the anchor-withdrawing locking ring 132. Moreover, the primary power structure 11 can drive the anchor-withdrawing locking ring 131 to move back and forth along the length direction of the anchor cable 18, and can drive the anchor-withdrawing locking ring 131 to compress or release the anchor-withdrawing locking ring 132, so that the anchor-withdrawing locking ring 131 compresses the inner cavity radius of the anchor-withdrawing locking ring 132 in the radial direction to lock the anchor cable 18 through the anchor-withdrawing locking ring 132, or the anchor-withdrawing locking ring 131 releases the inner cavity radius of the anchor-withdrawing locking ring 132 in the radial direction to reset the anchor-withdrawing locking ring 132; when the anchor removing operation is performed, the primary power structure 11 drives the anchor removing fixing ring 131 to move in a preset direction, so that the anchor removing fixing ring 131 presses the inner cavity radius of the anchor removing locking ring 132 in a radial direction, the anchor removing locking ring 132 tightly presses (i.e. locks) the anchor cable 18, and therefore the anchor removing fixing ring 131, the anchor removing locking ring 132 and the anchor cable 18 are linked, and in this case, the anchor removing fixing ring 131, the anchor removing locking ring 132 and the anchor cable 18 can continue to move in the driving direction when the primary power structure 11 drives the anchor removing operation. Then, under the condition that the anchor withdrawing locking ring 132 compresses the anchor cable 18, the primary power structure 11 continuously drives the anchor withdrawing fixing ring 131 to move towards the large caliber end part of the anchor withdrawing locking ring 132, so that the anchor cable 18 can be driven to move along the moving direction of the anchor withdrawing fixing ring 131 in the locking process of the anchor cable 18, and the anchor plug 19 is driven to move out of the anchor ring 17 to expose the clamping groove 171 arranged on the anchor plug 19.

In this embodiment, the shape of the anchor-removing locking ring 132 and the shape of the anchor-removing fixing ring 131 are not limited, and they are only required to meet the requirements of the present embodiment. Such as: the anchor-withdrawing fixing ring 131 is configured as a conical cylinder (the inner hole of the anchor-withdrawing fixing ring 131 is conical), and the anchor-withdrawing locking ring 132 comprises a plurality of anchor clamping pieces (such as three anchor clamping pieces), wherein the axial section of the anchor clamping pieces is conical, and the anchor clamping pieces enclose a conical tube to form the anchor-withdrawing locking ring 132. In addition, the anchor-removing fixing ring 131 and the anchor-removing locking ring 132 are coaxially disposed, and the large-caliber opening and the small-caliber opening in the anchor-removing fixing ring 131 are located on the same side as the small-caliber opening and the large-caliber opening of the anchor-removing locking ring 132, respectively. Notably, the plurality of anchor clips remain interlocked in the axial direction of the anchor withdrawal locking ring 132.

Of course, during the anchor removing operation, the primary power structure 11 drives the anchor removing fixing ring 131 to move towards the large caliber end of the anchor removing locking ring 132, so that the anchor removing fixing ring 131 gradually compresses the anchor removing locking ring 132, so that the anchor removing locking ring 132 (a plurality of anchor clamping pieces) gradually compresses the anchor cable 18, in this process, in order to avoid that the anchor removing locking ring 132 is excessively displaced under the pushing action of the anchor removing fixing ring 131, in this embodiment, a friction surface (such as an annular groove) is arranged on an inner surface (an inner surface of a plurality of anchor clamping pieces) of the anchor cable 18, which is close to the anchor cable 18, in the anchor removing locking ring 132, so as to increase the friction force between the inner surface (an inner surface of a plurality of anchor clamping pieces) of the anchor removing locking ring 132 and the anchor cable 18, so as to ensure the connection strength between the anchor removing locking ring 132 (a plurality of anchor clamping pieces) and the anchor cable 18 to a certain extent, and further limit the anchor removing locking ring 132 (a plurality of anchor clamping pieces).

Of course, in another embodiment, the following settings may also be made: in order to ensure the connection strength between the anchor withdrawal locking ring 132 and the anchor cable 18 when the anchor withdrawal locking ring 131, the anchor withdrawal locking ring 132 and the anchor cable 18 are linked, the anchor withdrawal locking ring 132 is limited, so the following settings are performed: a locking ring limiting piece 144 is arranged at the large-caliber opening end of the anchor-withdrawing locking ring 132, and when anchor-withdrawing operation (the primary power structure 11 drives the anchor-withdrawing locking ring 131 to move along the driving direction (the preset direction related to the text) so that the anchor-withdrawing locking ring 132 compresses the anchor cable 18, namely, the anchor-withdrawing locking ring 131, the anchor-withdrawing locking ring 132 and the anchor cable 18 are linked), the locking ring limiting piece 144 limits the large-caliber opening end of the anchor-withdrawing locking ring 132 in the length direction of the anchor cable 18; during anchor withdrawal operation, the locking ring limiting piece 144 limits the large-caliber opening end of the anchor withdrawal locking ring 132 in the length direction of the anchor cable 18, in this case, the primary power structure 11 drives the anchor withdrawal locking ring 131 to move towards the large-caliber opening end of the anchor withdrawal locking ring 132 in the length direction of the anchor cable 18, at this time, the locking ring limiting piece 144 can limit the anchor withdrawal locking ring 132, so that the anchor withdrawal locking ring 131 can compress the anchor withdrawal locking ring 132, and the anchor withdrawal locking ring 132 can compress the anchor cable 18, thereby realizing the linkage of the anchor withdrawal locking ring 131, the anchor withdrawal locking ring 132 and the anchor cable 18; then, under the condition that the anchor withdrawing locking ring 132 compresses the anchor cable 18, the primary power structure 11 continues to drive the anchor withdrawing fixing ring 131 to move towards the large caliber end part of the anchor withdrawing locking ring 132, so that the anchor cable 18 can be driven to move along the moving direction of the anchor withdrawing fixing ring 131 in the locking process of the anchor cable 18, and the anchor plug 19 is driven to move out of the anchor ring 17 to expose the clamping groove 171 arranged on the anchor plug 19.

Wherein, this locking ring limiter 144 includes: an elastic restoring member 1441; specifically, the elastic restoring member 1441 is disposed at a large-caliber opening end of the anchor-withdrawing locking ring 132 in the length direction of the anchor cable 18, and the locking ring limiter 144 further includes: an elastic return spring 14411 and a spring guide sleeve 14412, wherein one end of the elastic return spring 14411 is fixed in the spring guide sleeve 14412, and one end of the spring guide sleeve 14412 away from the elastic return spring 14411 abuts against a large-caliber opening end in the anchor-withdrawing locking ring 132, wherein the elastic force of the elastic return spring 14411 is parallel to the length direction of the anchor cable 18; therefore, during the anchor removing operation, the locking ring limiting piece 144 limits the large caliber opening end of the anchor removing locking ring 132 in the length direction of the anchor cable 18, in this case, the primary power structure 11 drives the anchor removing locking ring 131 to move towards the large caliber opening end of the anchor removing locking ring 132 in the length direction of the anchor cable 18, at this time, the anchor removing locking ring 132 can be limited by the compression rebound of the elastic return spring 14411, so that the anchor removing locking ring 131 can press the anchor removing locking ring 132, and the anchor removing locking ring 132 can be contracted to press the anchor cable 18, thereby realizing the linkage of the anchor removing locking ring 131, the anchor removing locking ring 132 and the anchor cable 18. The other end of the elastic return spring 14411 is fixed inside the primary power structure 11.

It should be noted that, during the resetting operation of the automatic anchor withdrawing device, the primary power structure 11 applies a force in an opposite direction (opposite direction along the preset direction), and the anchor withdrawing fixing ring 131 moves in an opposite direction along the length direction of the anchor cable 18 (opposite direction along the preset direction), so that the compression effect on the anchor withdrawing fixing ring 132 is relieved; in this process, to enable smooth disengagement of the anchor release locking ring 132 from contact with the cable rope 18, namely: the smooth release of compression between the anchor release locking ring 132 and the anchor cable 18 may be provided by any one or more of the following:

It should be noted that the anchor seat 161 is provided with a clutch through hole 1611 parallel to the length direction of the anchor cable 18, and the guide tube 151 and the guide post 152 are movably disposed in the clutch through hole 1611.

Therefore, in the anchor removing operation process, the primary power structure 11 drives the anchor removing fixing ring 131 to move towards the large-caliber end part of the anchor removing locking ring 132, and at this time, the locking ring limiting piece 144 limits the large-caliber opening end of the anchor removing locking ring 132 in the length direction of the anchor rope 18, so that the anchor removing fixing ring 131 gradually compresses the anchor removing locking ring 132, and then the anchor removing locking ring 132 compresses the anchor rope 18, so as to drive the anchor rope 18 to move along a preset direction (the preset direction is the moving direction of the anchor removing fixing ring 131 in the locking process of the anchor rope 18), and drive the anchor plug 19 to move out of the anchor ring 17 to expose the clamping groove 171 arranged on the anchor plug 19; then, the primary power structure 11 continues to apply force to the anchor-withdrawing fixed ring 131, because the anchor-withdrawing fixed ring 131, the anchor-withdrawing locking ring 132 and the anchor cable 18 are linked, at this time, the locking ring limiting piece 144 limits the large-caliber opening end of the anchor-withdrawing locking ring 132 in the length direction of the anchor cable 18, so that the anchor-withdrawing fixed ring 131 and the anchor-withdrawing locking ring 132 move along with the anchor cable 18 along a preset direction (the preset direction is the moving direction of the anchor-withdrawing fixed ring 131 in the locking process of the anchor cable 18); because one end of the guiding tube 151 in the clutch mechanism 15 is connected to the anchor-withdrawing locking ring 131, the guiding tube 151 and the anchor-withdrawing locking ring 131 are always in a linkage state, so that when the primary power structure 11 drives the anchor-withdrawing locking ring 131 to move towards the large-caliber end of the anchor-withdrawing locking ring 132 so that the anchor-withdrawing locking ring 131 gradually presses the anchor-withdrawing locking ring 132, the guiding tube 151 synchronously moves along with the anchor-withdrawing locking ring 131 along a preset direction (the preset direction is the moving direction of the anchor-withdrawing locking ring 131 in the locking process of the anchor rope 18), at the moment, the guiding tube 151 is in a moving state, and the guiding column 152 is in a non-moving state until the side wall of the strip-shaped hole in the preset direction abuts against the limiting piece 154, the guiding tube 151 drives the guiding column 152 to move along the preset direction (the preset direction is the moving direction of the anchor-withdrawing locking ring 131 in the locking process of the anchor rope 18), and the guiding column 152 drives the two-stage anchor-withdrawing mechanism 14 to clamp the clamping groove 171 exposed out of the anchor plug 19; of course, in the automatic anchor withdrawing device of the anchor cable, during the resetting operation, the primary power structure 11 applies a force in the opposite direction (the opposite direction of the preset direction), the anchor withdrawing fixing ring 131 moves reversely along the length direction of the anchor cable 18 (the opposite direction of the preset direction), and along with the reverse movement of the anchor withdrawing fixing ring 131 (the opposite direction of the preset direction), the guide tube 151 is driven to move reversely (the opposite direction of the preset direction), at this time, the guide post 152 is in a non-moving state until the limiting piece 154 abuts against the side wall of the bar-shaped hole in the opposite direction of the preset direction, and the guide tube 151 drives the guide post 152 to move reversely.

In another embodiment, on the basis of the above embodiment, the following arrangement is made for the above-mentioned secondary anchor-withdrawing mechanism 14:

the secondary elastic holding member 143 may be exemplarily configured as a spring, one end of which is fixed to the secondary anchor-withdrawing base 141, and the other end of which is connected between the other end of the limiting jaw 142 and the rotational connection point; in a case where one end of the limiting pawl 142 rotates relative to the rotational connection point to engage the engaging groove 171, the secondary elastic retainer 143 is in a compressed state to drive the protrusion 1422 to engage the engaging groove 171.

Specifically, in the present embodiment, the secondary anchor-withdrawing base 141, the limiting pawl 142 and the secondary elastic retaining member 143 are respectively in one-to-one correspondence with the guide posts 152; moreover, the end of the guide post 152 far from the guide tube 151 is connected with the limiting claw 142 in a matching manner, and this is not limited in this embodiment, and only needs to satisfy the requirements of this embodiment, for example: the end of the guide post 152 remote from the guide tube 151 is hinged to the end of the limit pawl 142 remote from the projection 1422. Of course, if at least one of the secondary anchor rest 141 and the limiting jaw 142 is not located in the axial direction of the guide post 152, an end of the guide post 152 remote from the guide tube 151 may be provided in a bent shape to fit the secondary anchor rest 141 and the limiting jaw 142.

In another embodiment, based on the above embodiment, a first through hole is formed in the secondary anchor removing base 141, the guide post 152 passes through the first through hole, and the guide post 152 can move back and forth along the length direction of the first through hole, and the moving stroke of the guide post 152 is greater than the depth of the first through hole;

moreover, a guiding limiter 15211 is fixed at an end of the guiding post 152 away from the guiding tube 151, and a longitudinal area of the guiding limiter 15211 is larger than a longitudinal area of the first through hole.

Of course, for the above-mentioned mating connection, the following arrangements are also possible: the limiting jaw 142 comprises a bar-shaped body 1421, wherein a protrusion 1422 is arranged at one end of the bar-shaped body 1421 (a protrusion 1422 is arranged at one end of the limiting jaw 142), a bending part 1423 is arranged at the other end of the bar-shaped body 1421 (a bending part 1423 is also arranged at the other end of the limiting jaw 142), a smooth arched part 1424 is arranged at the joint of the bending part 1423 and the bar-shaped body 1421 (the smooth arched part 1424 and the protrusion 1422 are respectively positioned at two sides of a rotation joint between the limiting jaw 142 and the secondary anchor withdrawing base 141), wherein the protrusion 1422 and the bending part 1423 are positioned at the same side of the bar-shaped body 1421, and the protrusion 1422 and the bending part 1423 are positioned at two sides of the protrusion 1422 body together with the smooth arched part 1424; moreover, the portion of the guide post 152 that does not pass through the first through hole is provided with a mating block 15212; when the projection 1422 is not clamped in the clamping groove 171 on the anchor plug 19, the matching block 15212 is slidably connected to the side surface of the strip-shaped body 1421, and at this time, the secondary elastic retaining member 143 is in a compressed state; when the protrusion 1422 is engaged with the engaging groove 171 on the anchor plug 19, the mating block 15212 slides over the rounded arch portion 1424 and is slidably connected to the side surface of the bent portion 1423, at this time, the secondary elastic retaining member 143 is released to a certain extent, but is still in a compressed state, and the secondary elastic retaining member 143 supports the rotation of the limiting pawl 142 based on its reverse elastic force, so that the protrusion 1422 on the limiting pawl 142 is engaged with the engaging groove 171. Moreover, the end of the guide post 152 far from the guide tube 151 passes through the first through hole formed in the secondary anchor withdrawal base 141 and then is fixed with a guide stopper 15211, and the longitudinal area of the guide stopper 15211 is larger than that of the first through hole, and the movement stroke of the guide post 152 is larger than the depth of the first through hole.

Specifically, in the anchor withdrawal process, the primary power structure 11 drives the anchor withdrawal locking ring 131 to move toward the large-caliber end of the anchor withdrawal locking ring 132, and at this time, the locking ring limiting member 144 limits the large-caliber opening end of the anchor withdrawal locking ring 132 in the length direction of the anchor cable 18, so that the anchor withdrawal locking ring 131 gradually compresses the anchor withdrawal locking ring 132, and then the anchor withdrawal locking ring 132 compresses the anchor cable 18 to drive the anchor cable 18 to move along a preset direction (the preset direction is: while the moving direction of the anchor-withdrawing ring 131 during the locking process of the anchor cable 18 moves, the guide tube 151 also moves synchronously along with the moving direction of the anchor-withdrawing ring 131 along with the preset direction (the preset direction is the moving direction of the anchor-withdrawing ring 131 during the locking process of the anchor cable 18), at this time, the guide tube 151 is in a moving state, and the guide post 152 is in a non-moving state until the side wall of the bar-shaped hole in the preset direction abuts against the limiting piece 154, the guide tube 151 drives the guide post 152 to move along the preset direction (the preset direction is the moving direction of the anchor-withdrawing ring 131 during the locking process of the anchor cable 18), the matching block 15212 on the guide post 152 slides over the smooth arch part 1424 from the bar-shaped body 1421 of the limiting pawl 142 and is connected to the side surface of the bending part 1423 in a sliding manner, at this time, the secondary elastic retaining piece 143 is released to a certain extent, but still in a compressed state, and the secondary elastic retaining piece 143 supports the rotation of the limiting pawl 142 based on the reverse elastic force thereof, so that the protrusion 2 on the limiting pawl 142 is clamped in the clamping groove 171; because the end of the guide post 152 far away from the guide tube 151 passes through the first through hole formed in the secondary anchor withdrawal base 141 and then is fixed with the guide limiting member 15211, the longitudinal area of the guide limiting member 15211 is larger than that of the first through hole, and the moving stroke of the guide post 152 is larger than the depth of the first through hole. Therefore, in the present embodiment, during the anchor removing operation, when the secondary elastic retaining member 143 supports the rotation of the limiting pawl 142 based on the reverse elastic force thereof so that the protrusion 1422 on the limiting pawl 142 is engaged with the engaging groove 171, the secondary power structure 11 continues to drive the anchor removing fixing ring 131, the anchor removing locking ring 132 and the anchor cable 18 which are configured to be interlocked together to move along the preset direction (the preset direction is the moving direction of the anchor removing fixing ring 131 during the locking of the anchor cable 18), so that the guide tube 151 continues to drive the guide post 152 to move along the preset direction (the preset direction is the moving direction of the anchor removing fixing ring 131 during the locking of the anchor cable 18), at this time, only the guide post 152 moves along the axial direction of the first through hole (the axial direction of the first through hole is parallel to the preset direction) between the guide post 152 and the secondary anchor base 141 until the guide post 152 moves along with the moving of the guide post 152 to abut against the secondary anchor base 141, which also causes the secondary anchor 152 to continue to move along the preset direction.

Of course, during the resetting operation of the automatic anchor withdrawing device, the guide post 152 will move along the opposite direction of the preset direction, at this time, the guide post 152 is in a moving state, and the guide tube 151 is in a non-moving state, until the limiting member 154 abuts against the side wall of the bar hole in the opposite direction of the preset direction, the mating block 15212 on the guide post 152 slides over the rounded arched portion 1424 from the bent portion 1423 of the limiting pawl 142 and is then slidingly connected to the side surface of the bar body 1421, at this time, the secondary elastic retainer 143 is reversely compressed, so that the limiting pawl 142 reversely rotates around the obtained rotationally connected point, and the protrusion 1422 on the limiting pawl 142 is separated from the clamping groove 171 on the anchor plug 19, thereby completing the resetting operation.

Of course, in another embodiment, if at least one of the secondary anchor rest 141 and the limiting jaw 142 is not located in the axial direction of the guide post 152, the end of the guide post 152 away from the guide tube 151 may be provided in a bent shape to fit the secondary anchor rest 141 and the limiting jaw 142.

Specifically, the bent end of the guide post 152 is configured in a "Z" shape, which includes: the first guide post 1521, the second guide post 1522 and the third guide post 1523, wherein the first guide post 1521, the second guide post 1522 and the third guide post 1523 are sequentially and fixedly connected, and the first guide post 1521 is parallel to the third guide post 1523, and the angle between the first guide post 1521 and the second guide post 1522 is complementary to the angle between the second guide post 1522 and the third guide post 1523. Wherein, the end of the first guide post 1521 far from the second guide post 1522 passes through the first through hole formed on the second-stage anchor withdrawal base 141 and then is fixed with a guide limiting member 15211, and the moving travel of the guide post 152 is greater than the depth of the first through hole; the third guide post 1523 and the guide tube 151 constitute the clutch mechanism 15 described above.

Of course, for the above-mentioned mating connection, the following arrangements are also possible: the limiting jaw 142 comprises a bar-shaped body 1421, wherein a protrusion 1422 is arranged at one end of the bar-shaped body 1421 (a protrusion 1422 is arranged at one end of the limiting jaw 142), a bending part 1423 is arranged at the other end of the bar-shaped body 1421 (a bending part 1423 is also arranged at the other end of the limiting jaw 142), a smooth arched part 1424 is arranged at the joint of the bending part 1423 and the bar-shaped body 1421 (the smooth arched part 1424 and the protrusion 1422 are respectively positioned at two sides of a rotation joint between the limiting jaw 142 and the secondary anchor withdrawing base 141), wherein the protrusion 1422 and the bending part 1423 are positioned at the same side of the bar-shaped body 1421, and the protrusion 1422 and the bending part 1423 are positioned at two sides of the protrusion 1422 body together with the smooth arched part 1424; moreover, a mating block 15212 is disposed at a portion of the first guide post 1521 that does not pass through the first through hole; when the projection 1422 is not clamped in the clamping groove 171 on the anchor plug 19, the matching block 15212 is slidably connected to the side surface of the strip-shaped body 1421, and at this time, the secondary elastic retaining member 143 is in a compressed state; when the protrusion 1422 is engaged with the engaging groove 171 on the anchor plug 19, the mating block 15212 slides over the rounded arch portion 1424 and is slidably connected to the side surface of the bent portion 1423, at this time, the secondary elastic retaining member 143 is released to a certain extent, but is still in a compressed state, and the secondary elastic retaining member 143 supports the rotation of the limiting pawl 142 based on its reverse elastic force, so that the protrusion 1422 on the limiting pawl 142 is engaged with the engaging groove 171. Moreover, the end of the first guide post 1521 far from the second guide post 1522 passes through the first through hole formed in the second anchor backing base 141 and then is fixed with a guide limiting piece 15211, the longitudinal area of the guide limiting piece 15211 is larger than that of the first through hole, and the moving travel of the guide post 152 is larger than the depth of the first through hole; the third guide post 1523 and the guide tube 151 constitute the clutch mechanism 15 described above.

Specifically, in the anchor withdrawal process, the primary power structure 11 drives the anchor withdrawal locking ring 131 to move toward the large-caliber end of the anchor withdrawal locking ring 132, and at this time, the locking ring limiting member 144 limits the large-caliber opening end of the anchor withdrawal locking ring 132 in the length direction of the anchor cable 18, so that the anchor withdrawal locking ring 131 gradually compresses the anchor withdrawal locking ring 132, and then the anchor withdrawal locking ring 132 compresses the anchor cable 18 to drive the anchor cable 18 to move along a preset direction (the preset direction is: while the moving direction of the anchor-withdrawing ring 131 during the locking process of the anchor cable 18 moves, the guide tube 151 also moves synchronously along with the moving direction of the anchor-withdrawing ring 131 (the preset direction is the moving direction of the anchor-withdrawing ring 131 during the locking process of the anchor cable 18), at this time, the guide tube 151 is in a moving state, while the guide column 152 (the first guide column 1521, the second guide column 1522 and the third guide column 1523) is in a non-moving state, until the side wall of the bar-shaped hole in the preset direction abuts against the limiting piece 154, the guide tube 151 drives the guide column 152 (the first guide column 1521, the second guide column 1522 and the third guide column 1523) to move along the preset direction (the preset direction is the moving direction of the anchor-withdrawing ring 131 during the locking process of the anchor cable 18), the matching block 15212 on the first guide column 1521 slides over the round arch portion 1424 from the bar-shaped body 1421 of the limiting pawl 142 and is then slidingly connected to the side face of the bending portion 1423, the secondary elastic retaining piece 143 is released to a certain extent, but still in a compression state, and the secondary elastic retaining piece is in a state, and the compression state, based on the elastic retaining piece is enabled to rotate on the reverse elastic retaining piece 171, so that the elastic retaining piece is enabled to be in the limiting and the limiting groove 142; because the end part of the first guide post 1521 far away from the second guide post 1522 passes through the first through hole formed in the second-stage anchor withdrawal base 141 and is fixed with the guide limiting piece 15211, the longitudinal area of the guide limiting piece 15211 is larger than that of the first through hole, and the moving travel of the guide post 152 is larger than the depth of the first through hole; the third guide post 1523 and the guide tube 151 constitute the clutch mechanism 15 described above. Therefore, in the present embodiment, during the anchor removing operation, the secondary elastic retainer 143 supports the rotation of the limiting pawl 142 based on the reverse elastic force thereof, so that when the protrusion 1422 on the limiting pawl 142 is engaged with the engaging groove 171, the secondary power structure 11 continues to drive the anchor removing fixing ring 131, the anchor removing locking ring 132 and the anchor cable 18 which are configured to be interlocked together to move along the preset direction (the preset direction is the moving direction of the anchor removing fixing ring 131 during the locking process of the anchor cable 18), so that the guide tube 151 continues to drive the guide post 152 to move along the preset direction (the preset direction is the moving direction of the anchor removing fixing ring 131 during the locking process of the anchor cable 18), and at this time, only the first guide post 1521, the second guide post 1522 and the third guide post 1523 which form the guide post 152 are moved along the axial direction of the first through hole (the axial direction of the first through hole is parallel to the preset direction), until the second guide post 1522 and the third guide post 1523 continue to move along the preset direction of the second guide post 152 along with the moving of the guide post 152.

Of course, in the process of performing the resetting operation by the automatic anchor withdrawing device, the primary power structure 11 applies a force in the opposite direction, the anchor withdrawing fixed ring 131 moves reversely along the length direction of the anchor cable 18, and along with the reverse movement of the anchor withdrawing fixed ring 131, the guide tube 151 is also driven to move reversely (in this text, the reverse direction is the reverse direction of the preset direction), at this time, the guide post 152 (the first guide post 1521, the second guide post 1522 and the third guide post 1523) is in a non-moving state, until the limiting member 154 abuts against the side wall of the bar hole in the reverse direction of the preset direction, the guide tube 151 drives the guide post 152 to move reversely, and the mating block 15212 on the first guide post 1521 in the guide post 152 slides over the rounded arch portion 1424 from the bent portion 1423 of the limiting pawl 142 and is then slidingly connected to the side surface of the bar body 1421, at this time, the secondary elastic retaining member 143 compresses reversely, so that the limiting pawl 142 rotates reversely around the obtained rotationally connecting point, and the protrusion 1422 on the limiting pawl 142 breaks away from the locking groove 171 on the anchor plug 19, thereby completing the resetting operation.

In another embodiment, on the basis of any one of the above embodiments, the following settings are made for the above-mentioned secondary power structure:

The secondary power structure comprises: second through hole 1412, guide rail 122, secondary anchor-removing elastic member 123 and limit structure 124.

Wherein the second through hole 1412 is formed on the second anchor-removing base 141, and the length direction of the second through hole 1412 is parallel to the length direction of the first through hole; the guide rail 122 passes through the second through hole 1412, and the secondary anchor-withdrawing base 141 can move back and forth along the length direction of the guide rail 122 based on the second through hole 1412; the secondary anchor-withdrawing elastic member 123 is sleeved on the outer wall of the guide rail 122, the secondary anchor-withdrawing elastic member 123 and the guide limiting member 15211 are positioned on the same side of the secondary anchor-withdrawing base 141, one end of the secondary anchor-withdrawing elastic member 123 is abutted against the secondary anchor-withdrawing base 141, and the secondary anchor-withdrawing elastic member 123 is in a compressed state before the guide limiting member 15211 is abutted against the secondary anchor-withdrawing base 141; the limiting structure 124 is disposed between the guide rail 122 and the inner wall of the second through hole 1412; therefore, before and after the guiding and limiting member 15211 abuts against the secondary anchor-removing base 141, the limiting structure 124 respectively constructs and releases the linkage between the secondary anchor-removing base 141 and the guiding rail 122.

In the above embodiment, the above-mentioned limit structure 124 is not limited, and it is only required to meet the requirements of the present embodiment, so in another embodiment, the following settings are made for the above-mentioned limit structure 124 on the basis of the above-mentioned embodiment:

the limiting structure 124 includes: spacing hole 1241, spacing elastic component, spacing fastener, spacing adaptation hole.

Wherein, the limiting hole 1241 is opened on the inner wall of the second through hole 1412; the limiting elastic piece is arranged in the limiting hole 1241, and the length direction of the limiting elastic piece is parallel to the length direction of the limiting hole 1241; the limiting clamping piece is connected to the elastic end of the limiting elastic piece; the limit adapting hole is formed on the outer wall of the guide rail 122, and the shape and the size of the limit adapting hole are matched with the groove and the size of the limit clamping piece; so, in the condition that the limiting clip cooperates with the limiting adapting hole, the secondary anchor-withdrawing elastic member 123 is in a compressed state, and the secondary anchor-withdrawing base 141 and the guide rail 122 keep linkage, namely: under the condition that the limiting clamping piece is matched with the limiting adapting hole, the secondary anchor withdrawal base table 141 and the guide rail 122 are in a relatively static state; in the case that the limiting clip is separated from the limiting adapting hole, the secondary anchor-withdrawing base 141 and the guide rail 122 form a sliding connection.

Specifically, in the anchor removing process described in any of the foregoing embodiments, before the guide limiting member 15211 abuts against the secondary anchor removing base 141, the limiting elastic member is in a compressed state to support the cooperation of the limiting clip member and the limiting adapting hole, so that the secondary anchor removing base 141 and the guide rail 122 remain linked, that is, the secondary anchor removing base 141 and the guide rail 122 are in a relatively static state; after the guiding limiting piece 15211 abuts against the secondary anchor-withdrawing base 141, under the action of the guiding limiting piece 15211, the guiding post 152 can drive the secondary anchor-withdrawing base 141 to continuously move along the preset direction, so that the limiting clamping piece between the secondary anchor-withdrawing base 141 and the guiding rail 122 is pushed to be separated from the limiting adapting hole, the limiting elastic piece is reversely compressed, and the linkage relation between the secondary anchor-withdrawing base 141 and the guiding rail 122 can be released, so that the secondary anchor-withdrawing base 141 and the guiding rail 122 form sliding connection; at this time, the secondary anchor-withdrawing elastic member 123 in a compressed state is released, and under the elastic force of the secondary anchor-withdrawing elastic member 123, the secondary anchor-withdrawing elastic member 123 drives the secondary anchor-withdrawing base 141 to continue to move along the preset direction (at this time, the guide post 152 also continues to drive the secondary anchor-withdrawing base 141 to continue to move along the preset direction); at this time, because the protrusion 1422 of the limiting claw 142 is clamped in the clamping groove 171 on the anchor plug 19, and the limiting claw 142 is fixed on the secondary anchor withdrawal base 141, along with the movement of the secondary anchor withdrawal base 141 in the preset direction, the secondary anchor withdrawal base 141 also drives the anchor plug 19 to move continuously in the preset direction, so as to drive the anchor plug 19 to separate from the anchor ring 17, thereby completing the anchor withdrawal operation.

Of course, in the process of resetting the automatic anchor withdrawing device of the anchor cable, the primary power structure 11 applies force in the opposite direction, and the anchor withdrawing fixing ring 131 moves reversely along the length direction of the anchor cable 18, so that the extrusion effect on the anchor withdrawing locking ring 132 is relieved; along with the reverse movement of the anchor fixing ring 131, the guide tube 151 is also driven to move reversely, at this time, the guide post 152 is in a non-moving state, until the limiting member 154 abuts against the side wall of the bar-shaped hole in the reverse direction of the preset direction, the guide tube 151 drives the guide post 152 to move reversely, so that the matching block 15212 on the guide post 152 (or the first guide post 1521 on the guide post 152) slides over the smooth arch portion 1424 from the bending portion 1423 of the limiting claw 142 and is connected to the side surface of the bar-shaped body 1421 in a sliding manner, at this time, the secondary elastic retaining member 143 is compressed reversely, so that the limiting claw 142 rotates reversely around the obtained rotational connection point; thereafter, the guide post 152 continues to move reversely along with the guide tube 151 until the guide limiting member 15211 on the guide post 152 is separated from the secondary anchor removing base 141 (or the guide limiting member 15211 is separated from the secondary anchor removing base 141 and the second guide post 1522 on the guide post 152 abuts against the secondary anchor removing base 141), so that the guide post 152 pushes the secondary anchor removing base 141 to move reversely on the guide rail 122 until the limiting clamp between the secondary anchor removing base 141 and the guide rail 122 slides into the limiting adapting hole again, and at this time, the secondary anchor removing elastic member 123 is in compression reset, and accordingly, the resetting operation of the anchor cable automatic anchor removing device is completed.
