DETAILED DESCRIPTION

[0039] As Figure 1 And Figure 2As shown, the clamping assembly of the wire strand repair robot in the embodiment comprises a clamping support base 31, and a pair of wire clamping jaws 32 for clamping the wire is arranged on the clamping support base 31. Each wire clamping jaw 32 is provided with a wire stabilizing clamping block 33 for clamping and stabilizing the wire, and a hollow pipe segment structure for clamping and stabilizing the wire is formed between the two wire stabilizing clamping blocks 33 to improve the coaxiality of the pre-stranded wire wrapped around the wire (which can be a power transmission line or a ground wire). The outer side of the wire stabilizing clamping block 33 is provided with a pre-stranded wire clamping module 34 for clamping the pre-stranded wire. The pre-stranded wire clamping module 34 comprises an adjusting head 341 fixed on the wire stabilizing clamping block 33, a plurality of mounting grooves 342 arranged in the radial direction of the wire are arranged on the adjusting head 341, a clamping seat 343 is arranged in the mounting groove 342, and an outer clamping block 344 and an inner clamping block 345 are arranged opposite to each other on the clamping seat 343. The outer clamping block 344 is fixed on the clamping seat 343, and the inner clamping block 345 is installed on the clamping seat 343 through a sliding block 346. The sliding block 346 is slidingly arranged in the clamping seat 343 and is fixed on the clamping seat 343 through a fastener 347. Clamping teeth for positioning the pre-stranded wire (as shown in a of Figure 1 ) are arranged on the clamping surfaces of the outer clamping block 344 and the inner clamping block 345. In the embodiment, two mounting grooves 342 arranged in the radial direction of the wire are arranged on the adjusting head 341, and a total of four mounting grooves 342 are arranged for clamping four pre-stranded wires, as shown in Figure 1 .

[0040] In order to firmly fix the pre-stranded wire on the clamping surfaces of the outer clamping block 344 and the inner clamping block 345, the clamping surfaces in the embodiment are in the form of a ring structure. In addition, due to the winding and bonding structure between the pre-stranded wire and the wire, the end of the pre-stranded wire is often loose. Considering that the protruding side of the pre-stranded wire is always in contact with the clamping surface of the outer clamping block 344 when the pre-stranded wire is clamped in the clamping assembly, in order to facilitate the withdrawal of the clamping assembly at the end of the operation without affecting the winding and bonding structure between the pre-stranded wire and the wire, as shown in Figure 2 , a roller 348 for abutting against the pre-stranded wire and capable of rolling is arranged in the middle of the clamping surface of the outer clamping block 344. The number of rollers 348 can be one or more. Since the roller 348 is in the form of a tube needle structure, it can also be referred to as a roller pin.

[0041] The movement of the wire clamping jaw 32 can also be driven by a required driving structure as needed. For example, as an alternative embodiment, as shown in Figure 1As shown, the clamping support base 31 in the embodiment is provided with a clamping jaw motor 311, a clamping jaw screw-nut module 312 and a bevel push connecting rod 313. The clamping jaw motor 311 is drivingly connected with the screw rod of the clamping jaw screw-nut module 312. The screw nut of the clamping jaw screw-nut module 312 is connected with two bevel push connecting rods 313 respectively. Each bevel push connecting rod 313 is connected with the outer end of a wire clamping jaw 32. The middle part of the wire clamping jaw 32 is hingedly fixed on the clamping support base 31. A wire stabilizing clamping block 33 is installed on the inner end of the wire clamping jaw 32. The clamping assembly is installed with all other parts based on the clamping support base 31. The two wire clamping jaws 32 are openable and closable movable parts. The clamping jaw motor 311 installed inside controls the rotation of the T10 type clamping jaw screw-nut module 312. In operation, the clamping jaw motor 311 drives the rotation of the screw rod of the clamping jaw screw-nut module 312. The screw nut of the clamping jaw screw-nut module 312 drives the movement of the two bevel push connecting rods 313. Thus, the two wire clamping jaws 32 can be clamped or opened by the forward rotation and reverse rotation of the clamping jaw motor 311. The wire stabilizing clamping block 33 on the wire clamping jaw 32 can clamp the pre-stranded wire and the wire.

[0042] As shown in the drawings, Figure 3 The embodiment also provides a wire strand breakage repairing robot. The robot body is provided with an up-and-down wire assembly 1, a walking assembly 2 and a repairing operation mechanism. The robot body is provided with a clamping assembly 3 for clamping the pre-stranded wire and the wire. The clamping assembly 3 is the clamping assembly for the wire strand breakage repairing robot as described above. In the embodiment, the clamping assembly 3 is on the central axis of the robot body.

[0043] As shown in the drawings, Figure 4 The up-and-down wire assembly 1 in the embodiment includes a groove plate 11, a winch mechanism 12 and a hook 13. The groove plate 11 is connected with the robot body. The winch mechanism 12 is fixed on the groove plate 11. The end of an insulating rope 120 on the winch mechanism 12 is connected with the hook 13. The winch mechanism 12 includes a winch motor 121, a winch box 122, a rope reel 123, a synchronous transmission mechanism 124, a reciprocating screw rod 125, a track 126 and a limiting section 127. The winch motor 121 drives the rope reel 123 through the winch transmission mechanism installed in the winch box 122. The rope reel 123 and the reciprocating screw rod 125 are connected through the synchronous transmission mechanism 124. The rope reel 123, the reciprocating screw rod 125 and the track 126 are installed on the winch box 122. The insulating rope 120 is arranged through the limiting section 127. The limiting section 127 is installed on the track 126 and threadedly cooperates with the reciprocating screw rod 125 to be driven by the reciprocating screw rod 125 to reciprocate on the track 126 to uniformly wind the insulating rope 120 on the rope reel 123 (to orderly and reciprocally wind the insulating rope 120 on the rope reel 123).

[0044] The winch transmission mechanism and the synchronous transmission mechanism 124 can adopt a required transmission mechanism as required. For example, as an optional embodiment, the winch transmission mechanism in the embodiment adopts a turbine worm with self-locking function, so that the worm is output by the winch motor 121 to rotate the rope disc 123 fixed with the turbine at a low speed, so as to increase the winch torque, and the synchronous mechanism 124 connected with the other end of the turbine drives the upper end of the rope disc 123 to rotate the reciprocating screw rod, so that the limiting joint 127 fixed on the reciprocating screw rod 125 moves on the rope disc 123. As an optional embodiment, the synchronous transmission mechanism 124 in the embodiment adopts a belt transmission.

[0045] Further, in order to improve the portability of the hook 13 suspended to the wire in the air and enhance the suspension reliability in the wire-up and wire-down process, as shown in Figure 4 the opening of the hook 13 in the embodiment is arranged downward and a rotatable pressing plate 131 is hingedly connected on one side of the opening, the front end of the pressing plate 131 is arranged opposite to the opening end of the hook 13, the rear end of the pressing plate 131 is connected with the end of the insulating rope 120 of the winch mechanism 12, a tension spring 132 is connected between the rear end of the pressing plate 131 and the hook 13 for pulling the pressing plate 131 away from the opening of the hook 13, through the above structure, the tension spring 132 can automatically pull the pressing plate 131 away from the opening of the hook 13 in the case that the insulating rope 120 is not under force, and the pressing plate 131 can close the opening of the hook 13 to prevent the wire from falling off the hook 13 in the case that the insulating rope 120 is under force.

[0046] As shown in Figure 3 it can be known that, as an optional embodiment, the robot body of the wire strand repair robot in the embodiment is provided with one wire-up and wire-down assembly 1 at each end of the central axis of the robot body, and the two wire-up and wire-down assemblies 1 are arranged in angular symmetry, that is, the opening directions of the hooks 13 of the two wire-up and wire-down assemblies 1 are opposite, so as to improve the reliability of the two wire-up and wire-down assemblies 1. Of course, more wire-up and wire-down assemblies 1 can also be adopted as required to realize the wire-up and wire-down operation of the robot body.

[0047] As shown in Figure 5 the walking assembly 2 in the embodiment includes a wire walking mechanism 21, a horizontal rotation mechanism 22 and a vertical moving mechanism 23 connected in sequence, the horizontal rotation mechanism 22 includes a horizontal rotation seat 221 and a turbine worm module arranged in the horizontal rotation seat 221, the horizontal rotation seat 221 is connected with the vertical moving mechanism 23, the wire walking mechanism 21 is fixedly connected with the turbine of the turbine worm module, a rotation motor 222 is installed on the horizontal rotation seat 221, the rotation motor 222 is in transmission connection with the worm of the turbine worm module for driving the wheel column 211 to rotate to avoid the wire (when the robot is wire-up and wire-down, the walking wheel is partially rotated to avoid the wire), compared with the relative translation avoidance mode, the structure is simpler, the strength is better, and the cost is lower.

[0052] The straightening over-bridge tooth 443 needs to be opened before the wire is fed in, so that the wire can be fed into the groove 442 of the straightening rotary tooth 441 after the wire is fed in, and the straightening rotary tooth 441 can be rotated after the wire is fed into the groove 442 of the straightening rotary tooth 441, so that the straightening over-bridge tooth 443 moves to the side of the groove 442 under the pushing force of the straightening fixing seat 44 to close the straightening over-bridge tooth 443 and the straightening rotary tooth 441 to form a complete gear, and the end of the straightening over-bridge tooth 443 and the joint part of the straightening rotary tooth 441 are provided with magnets in the embodiment to ensure that the straightening over-bridge tooth 443 is closed firmly and reliably.

The smoothing rotary tooth 441 is the key component of the smoothing assembly 4. The smoothing rotary tooth 441 is rotatable under the drive of the smoothing rotary motor 46. The relative rotation of the rotating seat 45 is used to achieve the purpose of smoothing the pre-stranded wire. In this embodiment, the sliding table module 42 is used to realize the lifting movement. The horizontal rotating table 43 is used to realize the horizontal rotation. Both of them are commercially available standard parts, which are used to adjust the horizontal angle and height of the smoothing fixed seat 44. The translation plate 41 is installed on a T16 screw rod slide block in the horizontal moving module on the robot body. The horizontal position of the smoothing part can be adjusted to adapt to the state and position of the wire that needs to be smoothed.

[0054] As Figure 8As shown, the repairing mechanism in the embodiment includes a rotating assembly 5 for rotating the pre-spiral to wrap outside the conductor, the rotating assembly 5 includes a rotating fixed seat 51 connected with the robot body, a rotating swing tooth 52 with a rotating bridge tooth 521 is arranged at the middle inner hole of the rotating fixed seat 51, the rotating swing tooth 52 is fixed at the middle inner hole of the rotating fixed seat 51 through the rotating limiting rings 522 on both sides, the rotating bridge tooth 521 is hingedly installed at the opening of the rotating swing tooth 52 and forms a complete gear with the rotating swing tooth 52 after being closed, a rotating drive motor 523 is installed on the rotating fixed seat 51 for driving the rotating swing tooth 52 to rotate to rotate the pre-spiral relative to the conductor, a plurality of front guide mechanisms 53 for guiding the pre-spiral are arranged at the front side of the rotating swing tooth 52, a plurality of rear guide mechanisms 54 for guiding the pre-spiral are arranged at the rear side of the rotating swing tooth 52, and the plurality of rear guide mechanisms 54 are commonly connected to the same pressure equalizing ring 55 (for making the robot have no potential difference between annular parts during live working). The rotating drive motor 523 drives the rotating swing tooth 52 to rotate, so that the rotating swing tooth 52 drives the front guide mechanism 53 and the rear guide mechanism 54 to rotate together, so that the pre-spiral can be rotated to be wound on the conductor. The rotating swing tooth 52 is a key component of the rotating assembly 5, in order to reduce the weight and access the conductor to be repaired, the missing tooth shape for installing the rotating bridge tooth 521 on the rotating swing tooth 52 is hollowed out to the center from the rotating swing tooth 52 in the embodiment, for reducing the weight and accessing the conductor to be repaired, and the hollow structure of the rotating swing tooth 52 passes through between the front guide mechanism 53 and the rear guide mechanism 54 to form a straight-through channel structure. Similarly, the rotating bridge tooth 521 needs to be opened before the wire is wound, so that the conductor enters the opening of the rotating swing tooth 52 after the wire is wound, and the rotating swing tooth 52 is rotated after the conductor enters the opening of the rotating swing tooth 52, so that the rotating bridge tooth 521 is moved to the opening side by the thrust of the rotating fixed seat 51 to close the rotating swing tooth 52 to form a complete gear, and the end of the rotating bridge tooth 521 and the joint part of the rotating swing tooth 52 are provided with magnets in the embodiment to ensure that the rotating bridge tooth 521 is closed firmly and reliably. For example, a magnet is arranged at the end of the rotating bridge tooth 521, the joint part of the rotating swing tooth 52 is made of iron, or the end of the rotating bridge tooth 521 or the whole is made of iron, the joint part of the rotating swing tooth 52 is provided with a magnet, or a magnet is arranged at the end of the rotating bridge tooth 521 and a magnet with opposite magnetism is arranged at the joint part of the rotating swing tooth 52.

[0055] Referring to Figure 8The front guide mechanism 53 in the embodiment comprises a front guide frame 531, a compression spring 532, a swing lever 533, and a wire passing groove 534. The front guide frame 531 is installed on the rotary rotating tooth 52 and is movably connected through a plurality of swing levers 533 and wire passing grooves 534. The wire passing grooves 534 of the plurality of front guide mechanisms 53 are arranged in central symmetry around the wire passing in the middle. A pulley or a roller is installed in the wire passing groove 534 to reduce the resistance of the pre-stranded wire in the passage and to limit the pre-stranded wire during winding repair. The compression spring 532 is connected between the swing lever 533 and the front guide frame 531 to apply a radial outward tension to the swing lever 533 on the front guide frame 531 so that the wire passing groove 534 together with the pre-stranded wire therein is opened outward to better wind the pre-stranded wire on the wire.

[0056] Referring to Figure 8 The rear guide mechanism 54 in the embodiment comprises a connecting plate 541 and a rear guide frame 542. The rear guide frame 542 is connected with the rotary rotating tooth 52 through the connecting plate 541. The rear guide frame 542 is provided with a guide hole 543. A pulley or a roller is installed in the guide hole 543 to reduce the resistance of the pre-stranded wire in the passage and to limit the pre-stranded wire during winding repair. Figure 8 It can be seen that the front guide mechanism 53 is located between the clamping assembly 3 and the rear guide mechanism 54. The distance from each rear guide mechanism 54 to the central axis of the wire is greater than the distance from the front guide mechanism 53 to the central axis of the wire. The guide passage formed by the rear guide mechanism 54 and the front guide mechanism 53 guides the pre-stranded wire to the central axis of the wire to reduce the maximum outer diameter of the pre-stranded wire rotating at the rear guide mechanism 54. Without the front guide mechanism 53, the maximum outer diameter of the pre-stranded wire rotating at the rear guide mechanism 54 is larger. In the process of winding the pre-stranded wire, the pre-stranded wire is easy to interfere with the robot body, which affects the operation range and efficiency of the wire repair. By increasing the front guide mechanism 53, the maximum outer diameter of the pre-stranded wire rotating at the rear guide mechanism 54 is reduced, so that longer pre-stranded wire can be wound, thereby improving the operation range and efficiency of the wire repair.

[0057] Referring to Figure 8 The horizontal seat 511 is installed below the rotary fixed seat 51. The horizontal seat 511 is fixed between the two ends and the rotary fixed seat 51 through the vertical support rod 512 to form a triangular shape to enhance the stability of the rotary fixed seat 51 during operation.

[0058] As shown in Figure 1 The robot body in the embodiment is provided with a horizontal movement module 6. The horizontal movement module 6 is used to realize the support and translation of the smoothing assembly 4 and the rotating assembly 5.

[0059] As shown in Figure 9As shown, the horizontal moving module 6 comprises a transmission seat 601, a horizontal moving motor 602, a main connecting plate 603, a horizontal moving plate 604, a guide shaft 605, a supporting frame 606, a horizontal moving screw 607, a positioning rod 608 and a machine box 609. The main connecting plate 603 is arranged in front and back, and holds two positioning rods 608 in the middle, forming the main body of the horizontal moving module. The machine box 609 is hung below, and the control system and power supply are in the machine box 609. The outer part of one end of the main connecting plate 603 is installed with two groups of transmission seats 601 and horizontal moving motors 602 in up and down positions, respectively controlling the rotation of the two horizontal moving screws 607 (T16 type) in the upper and lower parts of the main body, so that the two nuts on the two horizontal moving screws 607 move horizontally. One of the nuts is fixed and locked with the horizontal moving plate 604, and the other nut is fixed and locked with the supporting frame 606 and then locked on another horizontal moving plate 604, so that the two nuts drive the two horizontal moving plates 604 to move along the screw shaft, and the guide shafts 605 on both sides play a supporting and guiding role, so that the parts installed on the horizontal moving plate 604 move smoothly.

[0060] The working process of the broken wire repair robot of the embodiment is as follows: the line to be repaired is a power transmission conductor, before the robot is put on the line, the operating personnel tie the insulating rope 120 to the large hole at the rear end of the pressing plate 131 in the hook 13, and climb to the vicinity of the line to be repaired on the iron tower, use the operating rod to prop up the two hooks 13, and mount them on the line to be operated, and adjust the distance between the two hooks 13 to be approximately equal to the distance between the hoist mechanisms installed on the upper and lower line assemblies 1 at both ends of the robot, and then lower the insulating rope 120; the ground personnel connect the hanging insulating rope 120 in the rope disc 123 of the upper and lower line assemblies 1, at this time, the robot is started, the conductor clamping jaw 32 of the clamping assembly 3 is opened, the smoothing rotation tooth 441 of the smoothing assembly 4 and the rotation rotation tooth 52 of the rotation assembly 5 are opened to facilitate the robot to go on the line, the conductor enters this part, the walking wheels 213 at both ends of the robot are adjusted to the highest position of the robot, the transverse moving lead screw 607 in the transverse moving module 68 is adjusted, the rotation assembly 5 is farthest away from the clamping assembly 3, the smoothing assembly 4 is close to the clamping assembly 3, and the slide table module 42 of the smoothing assembly 4 is adjusted so that the smoothing assembly 4 is at a lower position; then the ground operating personnel select the corresponding pre-stranding wire according to the type of the conductor to be repaired, pass the four pre-stranding wires through the pre-stranding wire passage of the rotation assembly 5 respectively, and lock one end of the pre-stranding wire in the clamping seat 343 of the clamping assembly 3; start the hoist motor 121 in the upper and lower line assemblies 1 to drive the rope disc 123 to rotate and wind the insulating rope 120, and lift the whole robot, because the insulating rope 120 is tied to the large hole at the rear end of the pressing plate 131 in the hook 13, when the insulating rope 120 is stressed, the large hole end of the pressing plate 131 will be pulled down, so that the other end of the pressing plate 131 tightly presses the conductor at the hanging point position, thereby the hook 13 hanging on the conductor cannot move, at the same time, the gyroscope in the case 609 can automatically control the leveling to make the robot stably go on the line; when the robot rises to the position near the lower side of the conductor, the corner motor 222 in the walking part drives the turbine worm gear transmission in the horizontal corner seat 221 to horizontally rotate the walking wheels 213 at both ends by 180° to avoid the upper conductor, then the rope disc 123 continues to rotate to continue lifting the robot, when the walking wheels 213 are higher than the conductor, the walking wheels 213 at both ends return to the original position, the rope disc 123 reverses, the robot descends, the walking wheels 213 are mounted on the conductor, the rope disc 123 continues to reverse, the insulating rope 120 tied with the pressing plate 131 is relaxed, and the load of the whole robot is transferred from the hook 13 to the walking wheels 213; at this time, the operating personnel on the iron tower use the operating rod to take off the hooks 13 at both ends of the robot, the rope disc 123 is rotated in the positive direction to lock the hooks 13 in the upper and lower line assemblies 1; the jacking wheel 216 rises to jack up the conductor, then the walking wheels 213 move to the position of the conductor that needs to be repaired, when reaching the repair position, the walking wheels 213 stop rotating, the stand motor 232 is started, the lifting lead screw nut module T12 is driven to lift the whole robot along the stands 231 at both ends to the position where the rotation rotation tooth 52 in the rotation assembly 5 is coaxial with the conductor axis;The wire clamping jaw 32 of the clamping assembly 3 is closed to clamp the wire, and the rotating assembly 5 is driven by the horizontal movement module 6 to move towards the clamping assembly 3 until the four wire passing grooves 534 at the front end of the rotating assembly 5 press the wire under the action of the pre-stranding wire, and then the rotating rotating tooth 52 rotates, which is automatically closed during rotation. At the same time, the rotating assembly 5 as a whole moves away from the clamping mechanism under the control of the horizontal movement screw 607 in the horizontal movement module 6, so as to drive the pre-stranding wire to rotate along its spiral direction, so as to wrap the wire. With the rotation of the rotating rotating tooth 52 of the rotating assembly 5, the pre-stranding wire gradually exits along its channel until it is completely removed. After the wire is completely covered by the pre-stranding wire, the control walking wheel 213 moves the entire robot to make the pre-stranding wire exit the clamping seat 343; the position needing to be straightened is observed and determined by the multi-point camera inside the robot, the sliding table module 42 controls the overall upward movement of the straightening assembly 4, and the front and rear positions are controlled by the horizontal movement screw 607 in the horizontal movement module 6. After the wire falls into the center of the straightening rotating tooth 441, the tightening motor 454 starts to rotate the positive and negative screw rod 451, so that the two clamping blocks 453 with the compression wheel 455 move towards each other to clamp the position. The straightening rotating motor 46 installed on the other side of the straightening fixed seat 44 drives the rotating seat 45 to rotate as a whole, so that the compression wheel 455 rolls around the wire to achieve the purpose of straightening and smoothing. After completing the repair and straightening work, the robot returns to the original wire position, and the operator uses the operating rod to re-mount the hook 13 on the wire to start the offline work of the robot. The offline process is opposite to the online process. After the robot is offline, the operator recovers the hook 13 from the wire, and thus the entire wire repair work of the robot is completed. Through the above method, the maintenance personnel can complete the wire repair without climbing the tower. This scheme has the advantages of greatly improving the work efficiency of the maintenance personnel and shortening the working time under the condition of ensuring safety. In summary, the wire breakage repair robot of the embodiment can quickly and efficiently realize the movement of the robot on the high-voltage wire, quickly repair the wire breakage point, and reduce the labor intensity of manual maintenance and improve the work efficiency. In addition, the robot has high intelligence and high structural reliability.
