Before working, an maintainer overhauls the actual situation of the cable according to the requirement, such as the distance between two telegraph poles, the weight of the cable and other data, adjusts the elasticity of the second elastic element 401 in advance to adapt to the pulling force required when tensioning different cables, and takes the elasticity of the second elastic element 401 as an example, the specific operation is as follows: the maintainer pulls the threaded rod 9 by using a spanner, the threaded rod 9 is gradually screwed into the first movable frame 6, meanwhile, the threaded rod 9 drives the connecting plate 14 to move backwards, the connecting plate 14 drives the limiting plate 10 to move synchronously through the rotating rod 402, the second elastic piece 401 is compressed, the second elastic piece 401 extrudes the elastic force of the first limiting wheel 12 to be improved, and when the maintainer needs to reduce the elastic force of the second elastic piece 401, the threaded rod 9 is only required to be pulled reversely.

Then, an maintainer carries the device to climb to the top of the telegraph pole, and takes a cable on the left side of the telegraph pole as an example, and installs the device on a support frame 3 corresponding to the required cable, and starts to clamp the cable.

When clamping a cable, an maintainer pulls the moving rod 304 upwards to separate the moving rod 304 from a corresponding blind hole on the first moving frame 6, the first elastic member 305 is stretched, then the moving device moves the cable between the moving roller 7 and the third extrusion wheel 308, then the maintainer releases the moving rod 304, the moving rod 304 is reset under the pulling force of the first elastic member 305, but because the telescopic end of the second electric push rod 306 is not contracted in the process, namely, the telescopic end of the second electric push rod 306, namely, the third extrusion wheel 308 fixedly connected with the second electric push rod 306 is not moved, at the moment, the cable is not clamped by the moving roller 7 and the third extrusion wheel 308, and only the third extrusion wheel 308 and parts connected with the third extrusion wheel are suspended on the cable.

After the cable is clamped between the moving roller 7 and the third extrusion wheel 308, an maintainer controls the first electric push rod 302 to extend through a remote control device, the telescopic end of the first electric push rod 302 drives the second moving frame 303 and upper parts thereof to move upwards, so that the two first extrusion wheels 3011 and the two second extrusion wheels 301 are separated, then the cable is positioned between the two first extrusion wheels 3011 and the two second extrusion wheels 301 through moving the device, then the maintainer controls the first electric push rod 302 to shrink through the remote control device, the first electric push rod 302 drives the second moving frame 303 and upper parts thereof to move downwards to reset until the first extrusion wheels 3011 and the second extrusion wheels 301 clamp the cable, and at the moment, the maintainer closes the first electric push rod 302 through the remote control device, so that the clamping step of the cable by the device is completed.

After the clamping of the cable is completed, an maintainer starts to operate the device to perform a wire tightening operation, the maintainer firstly controls the wind-up roller 4 to rotate anticlockwise through the remote control device, so that a pull rope connected between the wind-up roller 4 and the first movable frame 6 is released, after the pull rope is loosened, the first movable frame 6 loses the force for enabling the first movable frame 6 to extrude the rotating plate 2 and the limiting frame 5, the first movable frame 6 is separated from the rotating plate 2 and is hung on the cable to move freely along the cable at the same time, because the cable between two telegraph poles is overlong, the cable falls into an arc shape under the action of gravity, and at the moment, the movable roller 7 and the third extrusion wheel 308 do not clamp the cable, so that the first movable frame 6 and parts on the first movable frame can drive the third extrusion wheel 308 above the cable to roll towards the concave part in the middle of the cable by virtue of gravity.

When the first moving frame 6 moves to the middle depression of the cable or the pull rope is completely released, that is, the first moving frame 6 cannot continue to move at the moment, the overhauler closes the wind-up roller 4 through the remote control device and controls the telescopic end of the second electric push rod 306 to shrink, and the telescopic end of the second electric push rod 306 drives the third extrusion wheel 308 to move downwards through the moving block 307, so that the third extrusion wheel 308 and the moving roller 7 are matched to clamp the cable.

In the process of clamping the cable by the third extrusion wheel 308 and the moving roller 7, the moving block 307 drives the rotating rod 402 to rotate through the rack when moving downwards, so that the limiting plate 10 moves forwards, the elastic force of the second elastic piece 401 is released for a part, the moving block 307 moves downwards for a distance proportional to the elastic force of the second elastic piece 401, so that the elastic force provided by the second elastic piece 401 is finely adjusted according to the moving downwards distance of the rotating rod 402, namely, the thickness of the cable, so that the elastic force provided by the second elastic piece 401 is more suitable for the current cable, after the cable is clamped, a service personnel closes the second electric push rod 306 through a remote control device, and the winding roller 4 starts to rotate to wind a pull rope, and the cable is tensioned.

In the process of tensioning the cable, the wind-up roller 4 drives the first movable frame 6 to move rightwards along the cable through a winding pull rope, and the following two conditions exist in the process:

when the tension applied to the cable is greater than or equal to the tension applied to the second elastic member 401, that is, the tension applied to the cable is greater than or equal to the tension applied to the cable when the cable is tensioned, that is, the cable does not need to be tensioned, the cable is easily tensioned excessively, the normal falling radian of the cable cannot be ensured, the cable is easily damaged in the subsequent use process, therefore, the first movable frame 6 and the parts thereon are driven by the pull rope to move rightwards, the movable roller 7 drives the first unidirectional wheel 13 to roll anticlockwise through the connecting shaft 8, the first unidirectional wheel 13 pushes the first limiting wheel 12 forwards under the action of the inclined plane on the first unidirectional wheel 13 and the inclined plane on the first limiting wheel 12, the second elastic member 401 is compressed until the first limiting wheel 12 is separated from the first unidirectional wheel 13, and the process is repeated repeatedly, that is, the first limiting wheel 12 cannot effectively limit the first unidirectional wheel 13 until the first movable frame 6 is reset.

When the tensile force applied to the cable at this time is smaller than the elastic force of the second elastic piece 401, namely the cable is strained at this time, the pull rope drives the first movable frame 6 and parts on the first movable frame to move rightwards, and the movable roller 7 drives the first unidirectional wheel 13 to roll anticlockwise through the connecting shaft 8, but under the action of the second elastic piece 401, the first unidirectional wheel 13 cannot push the first limiting wheel 12 forwards through the inclined plane of the first unidirectional wheel 13 and the first limiting wheel 12, namely the first unidirectional wheel 13 is limited by the first limiting wheel 12 and cannot rotate, so that the movable roller 7 and the third extrusion wheel 308 cooperate to drag the clamped cable rightwards.

In the process of dragging the cable to the right, the cable on the left side of the moving roller 7 is gradually leveled, meanwhile, the required pulling force is continuously increased, when the cable on the left side of the moving roller 7 is leveled, the required pulling force is increased to be equal to or greater than the elastic force of the second elastic piece 401, namely, the pulling force born by the cable on the left side of the moving roller 7 is continuously close to the pulling force born by the cable when the cable is pulled to a proper radian, at the moment, the second elastic piece 401 starts to be compressed under the extrusion of the first unidirectional wheel 13 to the first limiting wheel 12, the first unidirectional wheel 13 is gradually separated from the first limiting wheel 12, the left side cable is still continuously pulled when the first unidirectional wheel 13 is still not separated from the first limiting wheel 12, the required pulling force is continuously increased, the first unidirectional wheel 13 is pushed to be continuously separated from the first limiting wheel 12, and after the first unidirectional wheel 13 is completely separated from the first limiting wheel 12, the first unidirectional wheel 13 starts to rotate, meanwhile, the device starts to move according to the motion when the cable is pulled by the elastic force of the second elastic piece 401, namely, the first frame is not kept to move until the tensile force born by the left side of the moving roller 7 is kept unchanged.

After the device is reset, an maintainer fixes the cable tensioned by the device, then the fixing work of the cable is completed, the maintainer integrally resets the device through the reverse operation, and the device is placed on another cable to repeat the operation.

Because the cable is not required to be tensioned when the tensioning force applied to the cable is normal, namely the cable is not excessively loosened, but the maintenance personnel are difficult to observe the loosening degree of the cable by naked eyes, the device also has the function of detecting the tightening degree and the tilting degree of the cable, and the operation principle is as follows:

before the cable is clamped by the device, at this time, the third moving frame 601 pushes the limiting block 603 through the fifth elastic piece 604 to limit the sixth moving frame 606, so that the sixth moving frame 606 cannot move rightwards under the tensile force of the sixth elastic piece 607, meanwhile, the sixth moving frame 606 continuously limits the fifth moving frame 605, and the fifth moving frame 605 limits the first moving frame 6, so that the first moving frame 6 still cannot slide along the cable by means of self gravity under the condition that the pull rope on the winding roller 4 is loosened.

When the device clamps a cable, namely, the second moving frame 303 extrudes the third moving frame 601 to move downwards, so that the third moving frame 601 drives the limiting block 603 to release the limiting of the sixth moving frame 606 through the fifth elastic piece 604, meanwhile, the fourth elastic piece 602 is compressed, the sixth moving frame 606 moves rightwards under the action of the pulling force of the sixth elastic piece 607, the sixth moving frame 606 drives the fifth moving frame 605 to move downwards in the rightwards moving process, the fifth moving frame 605 releases the limiting of the first moving frame 6, and the first moving frame 6 slides along the cable by virtue of self gravity under the condition that the wind-up roll 4 is loosened.

In the process of clamping the cable by the device, because the two first extrusion wheels 3011 and the two second extrusion wheels 301 clamp the cable, and natural bending radian exists on the cable, the rotating plate 2 rotates for a certain angle relative to the fixed frame 1, namely, the downward bending angle of the cable end is detected, when the rotating plate 2 rotates for a certain angle relative to the fixed frame 1, the connecting block 611 rotates along with the rotating plate 2, the connecting block 611 drives the telescopic end of the second hydraulic push rod 610 to move, so that the cavity in the second hydraulic push rod 610 is enlarged, the second hydraulic push rod 610 extracts hydraulic oil in the first hydraulic push rod 608 through a hose, the telescopic end in the first hydraulic push rod 608 carries the wedge block 609 thereon to move rightwards, away from the limiting block 603, and the follow-up normal movement of the limiting block 603 releases the limiting of the sixth moving frame 606.

After the cable is clamped by the device, because the detecting rod 612 and the first moving frame 6 are higher than the supporting frame 3, namely the upper part of the supporting frame, the cable is subjected to an upward extrusion force, when the tensile force applied to the cable is small and the cable is loose, the cable cannot be extruded downwards to the detecting rod 612 under the action of the elastic force of the detecting spring 613, namely the detecting rod 612 pushes the connecting plate 614 to move downwards for a small distance, so that the distance that the connecting plate 614 drives the telescopic end of the third hydraulic push rod 615 to move downwards is reduced, namely the hydraulic oil extruded into the first hydraulic push rod 608 by the third hydraulic push rod 615 through a hose is reduced, and when the tensile force applied to the cable is large and the cable is tight, the device is opposite in operation condition.

When the device detects that the downward bending angle of the cable end is small, and when the tightening force applied to the cable is large, namely, the hydraulic oil in the first hydraulic push rod 608 extracted by the second hydraulic push rod 610 through the hose is small, and the hydraulic oil extruded by the third hydraulic push rod 615 to the first hydraulic push rod 608 through the hose is large, the telescopic end of the first hydraulic push rod 608 finally drives the wedge block 609 to move leftwards to limit the limiting block 603, and at the moment, the second moving frame 303 extrudes the third moving frame 601 to move downwards, the third moving frame 601 stretches the fifth elastic piece 604, the wedge block 609 limits the limiting block 603, so that the limiting block 603 cannot move, namely, the limiting of the sixth moving frame 606 cannot be released, and therefore the cable is prevented from being tensioned under the condition that the cable is not required to be tightened, and useless workload is increased.

Because in the cable tensioning process, along with the improvement of the cable pulling force, the downward sinking angle of the cable is gradually reduced, and the pulling force of the cable is gradually increased, so that the wedge block 609 limits the limiting block 603 after tensioning is completed, the device cannot be completely reset, at this time, an maintainer needs to unlock the clamping of the two first extrusion wheels 3011 and the two second extrusion wheels 301 to the cable through the first electric push rod 302, so that the device does not keep the same angle with the cable any more, namely, the rotating plate 2 rotates a certain angle along the fixing frame 1, so that the wedge block 609 unlocks the limiting block 603, and then the maintainer pushes the handle on the sixth movable frame 606, so that the sixth movable frame 606 extrudes the limiting block 603 through the left inclined surface of the sixth movable frame 606, and the fifth elastic member 604 is compressed to complete resetting.
