  However, in such a conventional common operation rod, once the tip tool is attached to the attachment body, the angle of the tip tool with respect to the common operation rod is fixed. The direction to approach is decided. For this reason, it is necessary to work in an unreasonable posture, leading to exhaustion of the worker's physical strength and inconvenience such as the hand approaching the high voltage overhead wire.

  In order to eliminate such an inconvenience, it is conceivable to provide a mechanism that can adjust the angle of the tip tool with respect to the common operation rod. However, when adjusting the angle of the tip tool, the work is temporarily interrupted. It is necessary to bring the accessory tool close to the operator and adjust the angle of the accessory tool directly by the operator.If the angle of the accessory tool is inappropriate, it is necessary to adjust the angle again. Therefore, there is a disadvantage that the working time is wasted without permission.

  The present invention has been made in view of such circumstances, and eliminates the inconveniences described above, and by allowing any tip tool to be freely adjusted at hand after being attached to the attachment portion, the tip tool The main object is to provide a common operation rod that can easily adjust the angle of the robot and reduce the work time, and that can avoid work in an unreasonable system.

  In order to achieve the above object, a shared operation rod according to the present invention includes a cylindrical operation rod main body, an attachment portion that is provided on one end side of the operation rod main body and to which a tip tool can be detachably attached, A tilt operation unit provided on the other end side of the operation bar main body and operable, a first tilt mechanism provided between the operation bar main body and the tilt operation unit, the operation bar main body and the attachment unit A second tilting mechanism provided between the first tilting mechanism and the first tilting mechanism, wherein the first tilting mechanism moves integrally with the tilting operation portion; and Formed at the end of the power transmission mechanism supported inside, the second end side spherical body that contacts the first end side spherical body so as to be able to transmit power, the second tilting mechanism, A first tip-side spherical body that moves integrally with the attachment portion; and Formed at the tip of the interior of the power transmission mechanism of the body, it is characterized in that it is constituted by said first distal end side spherical body and be able to transmit power abuts the second distal end side spheroids.

  Therefore, when the tilting operation unit is operated to change the angle with respect to the operating rod main body, the first terminal spherical body integrated with the tilting operation unit rotates or displaces, and the first end spherical body that is in contact with the tilting operation unit is capable of transmitting power. The two end-side spheres are displaced as the first end-side sphere is rotated or displaced. Then, the displacement of the second end side spherical body is transmitted to the second front end side spherical body through the power transmission mechanism, and the second front end side spherical body is displaced, and comes into contact with the second end side spherical body so as to be able to transmit power. The first tip side spherical body rotates or displaces in accordance with the displacement of the second tip side spherical body, and the angle of the attachment portion that moves integrally with the first tip side spherical body changes with respect to the operation rod main body. Is done.

  Therefore, since the angle of the attachment part can be arbitrarily adjusted by the operation of the common operation bar, it is possible to arbitrarily adjust the approach direction of the common operation bar with respect to the work location. In order to change the angle of the tool, it is not necessary to bring the attachment part close to the hand during work.

  Here, the power transmission mechanism may be configured by connecting a plurality of transmission rods supported in a tiltable manner inside the operation rod main body in series. The transmission rods may be connected via a universal joint such as a spherical joint or a universal joint.

  Further, the power transmission between the first terminal side spherical body and the second terminal side spherical body and the power transmission between the first tip side spherical body and the second tip side spherical body are spherical. The spherical body may be made of a non-slip material in order to increase the frictional resistance at the contact portion between the bodies, or a layer of a non-slip material may be provided on the surface of the spherical body.

It may be so that.

  Further, in order to make the tilting operation unit and the attachment unit face the axial direction of the operation bar main body in a normal time when no operation force is applied to the tilting operation unit with respect to the rod-shaped part, the first tilting mechanism includes A coil spring that covers the periphery of the first terminal-side spherical body and the second terminal-side spherical body is disposed between the tilt operation portion and the operation rod main body, and the second tilt mechanism includes A coil spring that covers the periphery of the first tip-side spherical body and the second tip-side spherical body may be disposed between the attachment portion and the operation rod main body.

  The coil spring can be either a tension spring (pull spring) or a compression spring (push spring), but the first end-side spherical body, the second end-side spherical body, and the first tip-side spherical body. In order to urge the body and the second tip side spherical body in the direction of pressing each other, it is preferable to use a tension spring.

  As described above, according to the common operation rod according to the present invention, the operation rod main body, the attachment portion provided on one end side of the operation rod main body to which the tip tool can be detachably attached, and the operation rod main body A tilting operation portion that is provided on the other end side and can be operated; and a first end-side spherical body that moves integrally with the tilting operation portion between the operating rod main body and the tilting operation portion; The first tilting mechanism, which is provided at the end of the power transmission mechanism supported inside the operation rod main body and is constituted by the first end-side spherical body and the second end-side spherical body abutting so as to be able to transmit power. A first tip side spherical body that moves integrally with the attachment portion between the operating rod main body and the attachment portion, and a power transmission mechanism that is provided at the tip of the power transmission mechanism and the first tip side spherical body. Second tilting mechanism configured by a second tip side spherical body that abuts on the second side Therefore, when the tilting operation part is operated to change the angle with respect to the operation bar main body, the angle of the attachment part with respect to the operation bar main body can be changed, and after attaching any tip tool to the attachment part, Even without bringing the tip tool close to the hand, the angle can be freely adjusted by the hand operation.

  For this reason, it is possible to easily adjust the angle of the tip tool at the hand of the common operation rod, so that the workability can be improved and the working time can be shortened. Work can be avoided.

Further, a draining drain (water draining collar 7) at the time of raining is fitted and fixed to the tip end side (substantially the center between the limit collar 5 and the attachment portion 3) of the operating rod main body 2 with respect to the limit collar 5. These limit collar 5 and draining collar 7 are made of soft synthetic rubber.

  The attachment part 3 is for attaching the joint part 10 of a tip tool such as an installation short circuit tool. The peripheral surface of the attachment main body 11 to which the joint part 10 is attached is formed with a pair of cylindrical protrusions. The locking projections 12 project radially outward at positions on the opposite side in the circumferential direction (projecting radially at positions 180 ° out of phase). Also, a hole (not shown) is formed in the upper surface of the attachment main body 11 substantially at the center, and a convex member 13 protrudes from the space formed inside the attachment main body 11 through this hole. The convex member 13 is always urged in the protruding direction by a built-in spring (not shown) housed in a space in the attachment body 11 and can be displaced in the axial direction.

  In addition, the joint part 10 of the tip tool attached to the attachment part 8 is formed in a bottomed cylindrical shape whose end is opened so that the attachment main body 11 can be inserted, and on the peripheral surface, two opposing parts are formed. A T-shaped engagement groove (not shown) is formed on the top.

  Further, a flange 15 projecting outward from the outer peripheral surface is provided at the end of the attachment portion 3 on the end side, and between the flange 15 and the attachment main body 11, the outer periphery extends along the axial direction. A screw shaft portion 16 on which a screw is formed, and a lock nut that engages with the screw shaft portion 16 so as to be able to advance and retract in the axial direction of the operation rod main body 2 and locks a tip tool attached to the attachment main body 11 17 is provided.

  Therefore, the attachment main body 11 of the common operation rod 1 is inserted into the joint portion 10 of the tip tool, and in this state, the attachment main body 11 is rotated to engage the locking protrusion 12 with the engaging groove of the joint portion 10. Later, in order to prevent looseness in the attached state, the lock nut 17 is turned to bring the lock nut 17 into contact with the joint portion 10 of the tip tool to form a lock state.

  The tilting operation portion 4 is a rod-shaped member having a diameter substantially equal to that of the grip portion 6 of the operation rod main body 2, and a distal end portion is provided with a flange 18 projecting outward from the outer peripheral surface. The part is provided with a joint part 19 to which another common operation bar or an extension rod can be detachably attached.

  As shown in FIG. 3, a first tilt mechanism 20 is provided between the operation rod main body 2 and the tilt operation portion 4, and between the operation rod main body 2 and the attachment portion 3. The second tilting mechanism 30 is provided.

  The first tilting mechanism 20 is fixed to the tip of a rod 21 attached to the tip of the tilting operation unit 4. The first distal spherical body 22 that moves integrally with the tilting operation unit 4, and the operation rod main body. 2 is constituted by a second end-side spherical body 23 which is fixed to the end of the power transmission mechanism 40 supported inside 2 and abuts on the first end-side spherical body 22.

  In this example, a first holder 24 that slidably holds a first end-side spherical body 22 is fixed to the end of the operating rod body 2, and the first holder 24 is formed around the first holder 24. The fastening flange 24a is abutted against the fastening flange 2a formed on the peripheral surface at the end of the operation rod body 2, and is fastened in the axial direction by an adhesive or a screw (not shown). In addition, the first holder 24 has a receiving portion 24b having an opening on the operating rod main body side larger than the diameter of the first terminal spherical body 22 and an opening on the terminal end smaller than the diameter of the first terminal spherical body 22. The first end-side spherical body 22 is formed to be displaced toward the operating rod main body side by the receiving portion 24b of the first holder 24, but it is prevented from coming out of the receiving portion 24b toward the end side.

  Further, between the fastening flange 24a of the first holder 24 and the flange 18 of the tilting operation unit 4, the first holder 24 and the tilting operation unit 4 are always attached in a direction to be attracted to each other. A biased coil spring (tensile spring) 25 is provided.

  By the coil spring 25 provided around the first terminal side spherical body 22 and the second terminal side spherical body 23, the first terminal side spherical body 22 and the second terminal side spherical body 23 are tilted. Even when the portion 4 is tilted, forces that press each other are urged, and in the normal time when the tilt operation portion 4 is not operated, the axial direction of the tilt operation portion 4 is the axis of the operation rod main body 2. I try to match the direction.

  Around the coil spring 25, a cylindrical cover 26 is engaged at one end with the back surface of the flange 18 of the tilt operation unit 4 and the other end is engaged with the back surface of the fastening flange 2 a of the operation rod body 2. Covered. The cover 26 is made of an elastic material such as synthetic rubber, and is formed of an elastically deformable soft material that is deformed in accordance with the tilting operation of the tilting operation unit 4.

  The second tilting mechanism 30 is fixed to the tip of a rod 31 attached to the end of the attachment main body 11, and moves with the first tip-side spherical body 32 that moves integrally with the attachment main body 11. 2 is constituted by a second tip-side spherical body 33 which is fixed to the tip of the power transmission mechanism 40 supported inside 2 and abuts on the first tip-side spherical body 32.

  In this example, a second holder 34 that slidably holds the first tip-side spherical body 32 is fixed to the tip of the operating rod body 2, and the second holder 34 is formed around the second holder 34. The fastening flange 34a is abutted against the fastening flange 2b formed on the peripheral surface of the distal end of the operation rod main body 2, and is fastened in the axial direction by an adhesive or a screw (not shown). In addition, the second holder 34 has a receiving portion 34b having an opening on the operation rod main body side larger than the diameter of the first tip side spherical body 32 and a tip end side smaller than the diameter of the first tip side spherical body 32. The first tip side spherical body 32 is formed to be displaced toward the operating rod main body by the receiving portion 34b of the second holder 34, but the tip end side is prevented from coming out of the receiving portion 34b.

  Further, between the fastening flange 34a of the second holder 34 and the flange 15 of the attachment part 3, the second holder 34 and the attachment part 3 are always urged in a direction to be attracted to each other by being fixed to the flanges. A coil spring (tensile spring) 35 is provided.

  Even when the second tip side spherical body 33 is displaced by the coil spring 35 provided around the first tip side spherical body 32 and the second tip side spherical body 33, the first tip side spherical body 32 is arranged. And the second tip side spherical body 33 are pressed against each other, and in the normal time when the tilting operation portion 4 is not operated, the axial direction of the attachment portion 3 is set to the operation rod main body 2. It is made to coincide with the axial direction.

  The coil spring 35 is covered with a cylindrical cover 36 having one end locked to the back surface of the flange 15 of the attachment portion 3 and the other end locked to the back surface of the fastening flange 2 b of the operation rod body 2. It has been broken. The cover 36 is made of an elastic material such as synthetic rubber, and is formed of a soft material that is elastically deformed as the attachment portion 3 is tilted.

  The surfaces of the first end-side spherical body 22 and the second end-side spherical body 23 that are in contact with each other, and the first tip-side spherical body 32 and the second tip-side spherical body 33 are in contact with each other. Concavities and convexities 22 a, 23 a, 32 a, and 33 a that mesh with each other are formed on the surface, and if the first end-side spherical body 22 is rotated or displaced, the second end-side spherical body 23 that abuts on this will slide. In addition, when the second tip side spherical body 33 is displaced, the first tip side spherical body 32 in contact with the second tip side spherical body 33 is rotated or displaced without slipping.

The irregularities 22a, 23a, 32a, and 33a formed on the surface of each spherical body are formed only in a range where the spherical bodies are in contact with each other even if they are formed on the entire circumference of each spherical body. It may be a thing.
In this example, the first end-side spherical body 22, the second end-side spherical body 23, and the second end-side spherical body 33 are formed to have the same diameter, The first tip spherical body 32 is formed to have a relatively small diameter as compared to these spherical bodies.

  The power transmission mechanism 40 provided inside the operation rod main body 2 is configured by connecting a plurality of transmission rods 41 supported in a tiltable manner inside the operation rod main body 2 in series. Specifically, inside the operation rod main body 2, a sphere 42 provided at the center of the transmission rod 41 is rotatably held by an annular bearing portion 43 protruding from the inner wall of the operation rod main body 2. The ends of the mating transmission rods 41 are connected by a universal joint 44 such as a spherical joint.

  The universal joint 44 used here preferably has a structure with some play, since the portions connected to each other in the axial direction of each transmission rod 41 are displaced by the tilting of the transmission rod 41, and in this example, The spherical body 44a is provided at the tip of one of the adjacent transmission rods 41, and the bottomed cylindrical portion 44b on which the sphere 44a slides is provided at the tip of the other rod.

  In the above configuration, when the work is performed after the tip tool is mounted on the tip portion of the common operation rod 1, the grip portion 6 of the operation rod body 2 is gripped by one hand, and the tilt operation portion is operated by the other hand. 4, when the tip tool approaches the work site and the inclination of the tip tool with respect to the common operation rod 1 is changed during the operation, the grip portion 6 of the operation rod body 2 is grasped with one hand, The tilt operation unit 4 is tilted with respect to the operation rod main body 2 with the other hand.

  Then, as shown in FIG. 4, the first end-side spherical body 22 that is integral with the tilting operation unit 4 rotates, and the second end-side spherical body 23 that is in contact with the second end-side spherical body 23 so that power can be transmitted is The first spherical body 22 is displaced as the first spherical body 22 rotates.

  At this time, with the rotation of the first terminal spherical body 22, the second terminal spherical body 23 tilts around the spherical body 42 provided in the intermediate portion of the transmission rod 41 and is displaced so as to draw a large arc. Therefore, when the position of the first terminal spherical body 22 supported by the first holder 24 is fixed, the first terminal spherical body 22 and the second terminal spherical body 23 are in contact with each other. May leave.

  Such inconvenience can be dealt with by adjusting the size of the irregularities 22a, 23a, 32a, 33a formed on the surface of each spherical body, but in the present configuration example, the first holder The coil spring 25 provided between the fastening flange 24a and the flange 18 of the tilting operation portion 4 is a tension spring, and the bearing portion 24b of the first holder 24 has a shape that is largely open to the operation rod body side. The first end-side spherical body 22 can be brought into contact with the second end-side spherical body 23 so as to press it, so that the contact state is not carelessly separated and the spherical bodies do not slip.

  The displacement of the second end spherical body 23 is transmitted to the second distal spherical body 33 via each transmission rod 41 of the power transmission mechanism 40, and is in contact with the second distal spherical body 33 so that power can be transmitted. The first tip side spherical body 32 rotates with the displacement of the second tip side spherical body 33, and the angle of the attachment unit 3 that moves integrally with the second tip side spherical body 33 is changed.

  Also here, the second tip side spherical body 33 tilts around the sphere 42 provided at the intermediate portion of the transmission rod 41 and is displaced so as to draw a large arc. If the position supported by the second holder 34 is fixed, the contact state between the first tip side spherical body 32 and the second tip side spherical body 33 may be separated, but the second holder 34 The coil spring 35 provided between the fastening flange 34a and the flange 15 of the attachment portion 8 is a tension spring, and the bearing portion 34b of the second holder 34 has a shape that opens largely to the operating rod body side. The first tip side spherical body 32 can be brought into contact with the second tip side spherical body 33 so as to press it, so that the contact state is not carelessly separated and the spherical bodies do not slip.

  Therefore, since the angle of the attachment part 3 can be arbitrarily adjusted by the operation at hand of the common operation rod 1, the approach direction of the common operation rod 1 with respect to the work location can be arbitrarily adjusted. Further, it is not necessary to bring the attachment part 3 close to the hand during the operation in order to change the angle of the tip tool.

  In the above-described example, the spherical bodies constituting the first tilting mechanism 20 and the second tilting mechanism 30 are the first end-side spherical body 22, the second end-side spherical body 23, and the second tip. Since the side spherical body 33 is formed to have the same diameter, the diameter of the first tip side spherical body 32 is relatively small compared to these spherical bodies. Even when the tilting angle of the tilting operation unit 4 is small, the tilting angle of the attachment unit 3 can be increased.

  In the above configuration, the irregularities 22a, 23a, 32a, 33a are provided on the surface of each spherical body to transmit the power from the tilting operation unit 4, but the first terminal-side spherical body 22 is provided. 5 is reliably transmitted to the second distal spherical body 23, and the movement of the second distal spherical body 33 is reliably transmitted to the first distal spherical body 32. As shown, the first end-side spherical body 22 and the second end-side spherical body 23, and the first tip-side spherical body 32 and the second tip-side spherical body 33 are kept in contact with each other. Thus, the periphery may be covered with a holding member 50 made of an elastic material.

  Even in such a configuration, when the angle of the tilting operation unit 4 with respect to the operation rod main body 2 is changed, the displacement of the first end-side spherical body 22 is transmitted to the second end-side spherical body 23, and the second end-side The displacement of the spherical body 23 is transmitted to the second tip side spherical body 33 via each transmission rod 41 of the power transmission mechanism 40, and the displacement of the second tip side spherical body 33 is the first tip side spherical body. Since the angle with respect to the operation rod main body 2 of the attachment part 3 that is transmitted to the first end side spherical body 32 and moves integrally with the first tip side spherical body 32 is changed, it is possible to achieve the same effects as the above configuration example. Become.
