Description

Technical Field

[0001] The present invention relates to the technical field of power tower maintenance, and in particular to auxiliary equipment for power tower maintenance and a use method thereof. Background Art

[0002] Power towers are an important part of transmission lines. Traditional power tower maintenance mainly relies on manual climbing and simple mechanical tools. This method is not only inefficient, but also has high safety risks. In recent years, although some mechanized maintenance equipment has emerged, such as lifting platform vehicles, these equipment are often bulky, complex to operate, and have certain requirements on the structure of the tower. Therefore, the development of a lightweight, efficient, safe and reliable auxiliary equipment for power tower maintenance has become an urgent problem that needs to be solved in the industry.

[0003] In the prior art, a large number of power tower maintenance and corresponding devices are also disclosed. Among them, for example, a Chinese patent with publication number CN107069541A discloses an overhead line maintenance device; it includes a walking mechanism and a wire-stringing mechanism arranged on the walking mechanism, the walking mechanism includes a left walking bracket and a right walking bracket, a crossbeam extending to the right is arranged on the upper part of the left walking bracket, a first dovetail groove is arranged on the bottom surface of the crossbeam, and a first dovetail tenon matched with the first dovetail groove is arranged on the top of the right walking bracket; the wire-stringing mechanism includes a pulley frame and an active pulley and a driven pulley arranged inside the pulley frame, a power platform is arranged at the lower front part of the pulley frame, a drive motor is arranged on the power platform, and the output shaft of the drive motor is connected to the rotating shaft of the active pulley through a flange, a control platform is arranged at the lower rear part of the pulley frame, and a CPU module is arranged on the control platform.

[0004] When in use, first place the left and right traveling brackets on the overhead line, then fasten the lower bracket to the lower part of the upper bracket by fasteners, and clamp the overhead line between the upper clamping body and the lower bracket by the second automatic telescopic rod. The relative movement between the left and right traveling brackets is achieved by the first automatic telescopic rod, and the forward movement of the wire-laying mechanism is achieved, which is convenient for the maintenance and replacement of the overhead line.

[0005] However, in the process of maintaining power towers using the above-mentioned existing technologies, there are still the following shortcomings: 1. Although the above-mentioned existing technologies can realize the forward movement of the wire-laying mechanism, shock-absorbing hammers are usually installed on the overhead lines to prevent the lines from vibrating, so that the shock-absorbing hammers will block their forward path during the movement, and the above-mentioned existing technologies cannot operate across the shock-absorbing hammers, so their scope of application is relatively small.

[0006] 2. During the maintenance of overhead lines, workers cannot avoid large movements and swings of their bodies, which affects their balance. However, the above-mentioned prior art cannot ensure the balance of workers when they are repairing overhead lines, which poses a safety hazard.

[0007] 3. During the movement, when the staff needs to stop to perform fixed-point maintenance on the overhead line, the above-mentioned prior art cannot be locked after stopping, so that during the staff's fixed-point maintenance of the overhead line, the above-mentioned prior art may move, thereby affecting the staff's maintenance of the overhead line.

[0008] Therefore, based on the above-stated viewpoints, there is still room for improvement in the overhead line maintenance methods of the prior art. Summary of the invention

[0038] The following is combined with Figure 1-Figure 9 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0039] The embodiment of the present application discloses an auxiliary equipment for maintenance of electric power towers. It should be noted that the auxiliary equipment for maintenance of electric power towers of the present application is mainly used in the maintenance process of overhead wires. In terms of technical effect, it can achieve alignment with overhead wires at different intervals through the adjustment of the bidirectional telescopic rod 11, which is convenient for installation and adaptation to overhead wires at different intervals and increases the scope of use. In particular, the gyroscope 21 can keep the equipment balanced during movement to prevent the balance box 1 from tilting due to strong winds or sideways movement of personnel, thereby greatly improving the safety of the equipment. Furthermore, the auxiliary equipment for maintenance of electric power towers can also achieve obstacle crossing during movement, and lock the overhead wires when the staff is maintaining the overhead wires that need to be maintained, and prevent the moving wheel 26 from rotating through the cooperation of the clamping groove 31 and the clamping block 35, thereby ensuring that the equipment cannot move during the maintenance process and ensuring the safety of the maintenance process.

[0040] Embodiment 1:

[0041] Reference Figure 1 As shown, an auxiliary equipment for maintaining an electric tower comprises a balancing box 1, the side wall of which is provided with two bidirectional telescopic rods 11 symmetrically distributed along its length direction, the telescopic ends of the two bidirectional telescopic rods 11 on the same side are commonly connected to a load-bearing rod 12, a plurality of unidirectional telescopic rods 13 are installed on the upper end of the load-bearing rod 12, and the telescopic ends of the plurality of unidirectional telescopic rods 13 are all connected to a moving device 2.

[0042] In the initial state, the two-way telescopic rod 11 and the one-way telescopic rod 13 are both in a retracted state, so as to facilitate the staff to carry and transport them to the top of the iron tower; it should be noted that the telescopic ends of the two-way telescopic rod 11 and the one-way telescopic rod 13 are provided with a self-locking mechanism, which can be locked after being stretched to a specified length to avoid automatic extension.

[0043] During the specific implementation process, first pull the two-way telescopic rod 11 to align the mobile device 2 with the overhead wire, which can be applied to overhead wires at various intervals, greatly improving the application range of the device; hang the device on the overhead wire between the towers, and then adjust the one-way telescopic rod 13 so that the length of the one-way telescopic rod 13 matches the height of the staff, which is convenient for the staff to perform subsequent maintenance on the overhead wire above; after the staff sits on the balance box 1, start the mobile device 2, and then the mobile device 2 drives the staff to move along the overhead wire, and the staff can observe and maintain the overhead wire; when encountering a shock-absorbing hammer on the overhead wire during the movement, the shock-absorbing hammer can be crossed by the mobile device 2. When it is necessary to maintain a certain section of the overhead wire, turn off the mobile device 2, and then the mobile device 2 can lock the overhead wire to prevent the staff from moving the equipment during the maintenance process, making it impossible for the staff to maintain it.

[0044] Reference Figure 2 , Figure 3 and Figure 4 As shown, in order to prevent the balance box 1 from shaking due to the tilt of the staff during the movement, a gyroscope 21 is provided in the present embodiment; specifically, a gyroscope 21 for maintaining balance is installed in the balance box 1, and the moving device 2 includes a cross bar 22 installed at the telescopic end of the one-way telescopic rod 13, and an L-shaped bracket 23 is connected to the bottom of the cross bar 22. The side wall of the L-shaped bracket 23 is provided with a sliding groove 24, and a transmission shaft 25 is rotatably connected in the sliding groove 24. The outer wall of the transmission shaft 25 is provided with a moving wheel 26, and the longitudinal section of the moving wheel 26 is funnel-shaped, and both sides of the moving wheel 26 have conical inclined surfaces inclined toward the side close to its axis, and the outer wall of the moving wheel 26 is provided with a V-shaped groove 27 for clamping the overhead wire.

[0045] Furthermore, in this embodiment, the mobile device 2 also includes a driving motor 28 installed on the upper end of the supporting rod 12 through a motor seat, multiple transmission shafts 25 located on the same supporting rod 12 and the output shaft of the driving motor 28 are connected through a belt drive, a bracket plate 29 is installed on the side of the cross bar 22, and a crossing mechanism 30 is installed at the bottom of the bracket plate 29.

[0046] It should be noted that the belt drive uses an elastic belt. When the one-way telescopic rod 13 is adjusted, the elastic belt adaptively expands and contracts, thereby ensuring the power transmission between the output shaft of the drive motor 28 and the transmission shaft 25; the gyroscope 21 is a prior art, and the rotational motion of the gyroscope 21 is stable and can resist external interference. When subjected to external torque, the gyroscope 21 adjusts the direction of its rotation axis through the precession effect to maintain balance.

[0047] In the specific implementation process, the moving wheel 26 is first moved to the upper end of the overhead wire, and then the V-groove 27 on the moving wheel 26 is aligned with the overhead wire and locked in. The V-groove 27 prevents the moving wheel 26 from detaching from the overhead wire during the movement, which greatly increases the stability of the equipment during the movement. After the staff sits on the balance box 1, the gyroscope 21 is started, so as to prevent the equipment from tilting in strong winds or when the staff turns sideways during the maintenance of the overhead wire, causing the staff to fall from the balance box 1, thereby greatly improving the safety of the equipment; then the drive motor 28 is started, and the output shaft of the drive motor 28 drives multiple drive shafts 25 and the moving wheel 26 to rotate through the belt drive. During the rotation of the multiple moving wheels 26, the friction force with the overhead wire drives the balance box 1 to move, thereby driving the staff to move. During the movement of the staff, the overhead wire is inspected and maintained, and there is no need to stand on the overhead wire and move slowly, which greatly improves the maintenance efficiency.

[0048] Reference Figure 3 As shown, a plurality of shock-absorbing hammers are usually installed on the overhead wires to separate the plurality of overhead wires. In order to be able to cross the shock-absorbing hammers during movement, a crossing mechanism 30 is provided in the present embodiment; specifically, the crossing mechanism 30 includes two vertical poles 301 hinged at the bottom of the bracket plate 29, two rotating wheel brackets 302 are hinged at the bottom of the cross bar 22, the transmission shaft 25 is rotatably connected between the two rotating wheel brackets 302, the opposite side walls of the two vertical poles 301 are hinged with a linkage rod 303, the end of the linkage rod 303 away from the vertical pole 301 is hinged with the middle part of the linkage rod 303, the opposite sides of the two vertical poles 301 are connected with a trigger rod 304, and the hinges between the vertical poles 301 and the bracket plate 29 and the hinges between the rotating wheel bracket 302 and the cross bar 22 are both installed with torsion springs for resetting (not shown in the figure).

[0049] It should be noted that the torsion spring always applies a torque to the upright pole 301 and the rotating wheel bracket 302 toward the side close to the forward direction of the device, so that the moving wheel 26 can automatically reset after being lifted.

[0050] In the specific implementation process, when the trigger rod 304 contacts the shockproof hammer during the movement, the trigger rod 304 rotates toward the side close to the moving wheel 26 under the obstruction of the shockproof hammer, and drives the linkage rod 303 to move toward the side close to the moving wheel 26, and the linkage rod 303 pushes the rotating wheel bracket 302 to move synchronously, and the rotating wheel bracket 302 rotates at the hinge with the cross bar 22, and drives the moving wheel 26 to gradually move upward, and the transmission shaft 25 slides along the sliding groove 24, and at the same time the linkage rod 303 and the vertical rod 301 rotate to a nearly horizontal state, so that when close to the shockproof When the moving wheel 26 on one side of the hammer moves to above the shock-proof hammer, the linkage rod 303, the vertical pole 301 and the moving wheel 26 will not collide with the shock-proof hammer, and continue to move forward to cross the shock-proof hammer. Subsequently, the torsion spring drives the vertical pole 301 and the rotating wheel bracket 302 to rotate and reset, and the rotating wheel bracket 302 drives the moving wheel 26 to move downward and reset, so that the V-shaped groove 27 is again stuck in the overhead wire and continues to drive the equipment forward. While driving the staff to move on the overhead wire, it can also automatically cross obstacles, greatly improving the scope of application of the device.

[0051] It should be noted that during the obstacle crossing process, only the two moving wheels 26 located flush with each other in the width direction of the balance box 1 will be lifted, and the moving wheels 26 on the same overhead wire will always be supported by more than two moving wheels 26, thereby ensuring the balance and movement of the equipment and further improving the safety of the equipment.

[0052] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in order to lock the moving wheel 26 during the maintenance of the overhead wire by the staff, so as to prevent the balance box 1 from moving and affecting the maintenance of the overhead wire by the workers, a locking block 33 is provided in this embodiment; specifically, a plurality of snap-in grooves 31 are provided on the inclined surface of the V-shaped groove 27, and the plurality of snap-in grooves 31 are distributed along the circumference of the axis of the moving wheel 26. A through hole 32 is provided at the bottom of the L-shaped bracket 23, and a locking block 33 is slidably connected in the through hole 32. The upper end of the locking block 33 is trapezoidal, and a bevel groove 34 for increasing friction is provided on the top of the locking block 33. The two ends of the locking block 33 are provided with a bevel groove 34 for increasing friction. The inclined surfaces are each installed with a plurality of snap-in blocks 35 corresponding to the snap-in grooves 31, support plates 36 are connected to both sides of the locking block 33, a return spring 37 is connected between the support plate 36 and the L-shaped bracket 23, two limit rods 38 are installed at the bottom of the L-shaped bracket 23, a support shaft 39 is rotatably connected between the two limit rods 38, a pull rod 40 is sleeved on the outer wall of the support shaft 39, one end of the pull rod 40 is hinged to the bottom of the locking block 33, the end of the pull rod 40 close to the locking block 33 is connected to a telescopic end, and the lower ends of the plurality of pull rods 40 located on the same overhead wire are hinged together with a lifting rod 41.

[0053] During the specific implementation process, when it is necessary to stop moving, turn off the drive motor 28, and then pull the lifting rod 41 downward. The lifting rod 41 drives the pull rod 40 to rotate along the support shaft 39, and the pull rod 40 rotates upward near the locking block 33, and drives the locking block 33 to move upward. The reset spring 37 adaptively retracts and contracts, and then the upper end of the locking block 33 contacts the overhead wire, thereby squeezing the overhead wire and increasing the friction through the oblique groove 34. At the same time, the clamping block 35 is clamped into the clamping groove 31, and the moving wheel 26 cannot rotate under the limit of the clamping block 35. Therefore, when the overhead wire needs to be maintained, the equipment is fixed to prevent the equipment from moving and improve the safety of the equipment; when the maintenance is completed, release the lifting rod 41, the reset spring 37 adaptively contracts, and drives the locking block 33 to move downward, and the locking block 33 drives the pull rod 40 to rotate and reset, start the drive motor 28 again, and continue to patrol and maintain the overhead wire.

[0054] It should be noted that a fixed block 42 for locking and limiting the lifting rod 41 is installed on the side wall of the single-way telescopic rod 13. After the lifting rod 41 is pressed down, it is clamped at the bottom of the fixed block 42, which can limit the lifting rod 41 and prevent the lifting rod 41 from rebounding and resetting under the action of the reset spring 37, thereby affecting the locking of the device and the fixed-point maintenance of the overhead wires.

[0055] Embodiment 2:

[0056] Refer to Figure 8 and Fig. 9 As shown, on the basis of the first embodiment, during the operation of the overhead wire, long-term wind vibration will cause the wire to wear at the fixed point, eventually causing it to drop. Therefore, in order to be able to pull the dropped wire during the maintenance of the overhead wire, based on this, in this embodiment, two sets of traction components are installed on both side walls of the balance box 1 along the length direction, and the traction component includes two bearing plates 51 symmetrically installed on the side wall of the balance box 1 up and down, and two rotating wheel telescopic rods 52 are installed on the opposite sides of the two bearing plates 51. The telescopic ends of the two rotating wheel telescopic rods 52 on the same bearing plate 51 are rotatably connected to a traction wheel 53, and the two rotating wheel telescopic rods 52 on the same bearing plate 51 on the side close to the moving direction of the balance box 1 are connected There is a clamping bent plate 54, and a supporting spring 55 is connected between the clamping bent plate 54 and the adjacent bearing plate 51. Both side walls of the balance box 1 are rotatably connected with two trigger rods 56 symmetrically distributed along the length direction thereof. The two trigger rods 56 on the same side of the balance box 1 are symmetrically distributed up and down and correspond to the position of the clamping bent plate 54. The trigger rod 56 and the corresponding clamping bent plate 54 are hinged. Both side walls of the balance box 1 in the length direction are rotatably connected with clamping plates 57. The two clamping plates 57 on the same side are located on the side of the trigger rod 56 away from the clamping bent plate 54. The two clamping plates 57 are symmetrical up and down and tiltedly distributed. A hinged rod 58 is hinged between the side of the trigger rod 56 away from the clamping bent plate 54 and the clamping plate 57.

[0057] In the specific implementation process, first adjust the one-way telescopic rod 13 close to the side of the dropped line so that the moving wheel 26 is flush with the overhead wire that has not been dropped, thereby hanging the equipment on the upper end of the overhead wire, and then pull the clamping bending plate 54 close to the side of the dropped line, the clamping bending plate 54 drives the telescopic end of the upper rotating wheel telescopic rod 52 to move upward, and drives the upper traction wheel 53 to move synchronously, the support spring 55 shrinks adaptively, so that a gap is formed between the upper traction wheel 53 and the lower traction wheel 53, and then the dropped overhead wire is placed between the two traction wheels 53, the clamping bending plate 54 is released, the support spring 55 rebounds and makes the two traction wheels 53 fit each other, thereby clamping the overhead wire between the two traction wheels 53.

[0058] It should be noted that the support spring 55 always applies elastic force to the clamping bending plate 54 toward the side close to the overhead wire, and when the overhead wire is located between the two traction wheels 53, the two traction wheels 53 do not fit together under the support of the overhead wire.

[0059] Start the drive motor 28, and the moving wheel 26 drives the equipment to move toward the tower where the line is disconnected. During the movement, the overhead wire that has been disconnected moves between the two traction wheels 53, and the traction wheel 53 rotates under the action of the friction force of the overhead wire. When the head of the overhead wire moves to the bottom of the traction wheel 53 on the side close to the moving direction of the equipment during the movement, the overhead wire moves out from between the traction wheels 53, and then the support spring 55 applies elastic force to the clamping bending plate 54, and the clamping bending plate 54 drives the telescopic end of the rotating wheel telescopic rod 52 to move toward the side close to the overhead wire. The two traction wheels 53 fit each other after losing the overhead wire, and at the same time, the two clamping bending plates 54 move synchronously with the traction wheel 53, and clamp the overhead wire to prevent the overhead wire from being detached from traction.

[0060] During the movement of the clamping and bending plates 54 towards each other, the clamping and bending plates 54 drive the trigger rod 56 to rotate along the rotating connection of the balance box 1. During the rotation of the trigger rod 56, the hinged rod 58 is driven to move toward the side close to the overhead wire. During the movement of the hinged rod 58, the clamping plate 57 is driven to rotate along the connection with the balance box 1, so that the two clamping plates 57 move away from one end of the hinged rod 58 and move toward each other, thereby further clamping the overhead wire to prevent the overhead wire from sliding out too quickly after separating from the traction wheel 53 and the clamping and bending plates 54 are not clamped in time. It should be noted that the opposite sides of the two clamping plates 57 gradually tilt toward the side close to the clamping and bending plates 54, so that the clamping plates 57 can increase the friction between the overhead wire and the overhead wire, and the friction is greater when the overhead wire falls on the side away from the moving direction of the equipment, thereby ensuring the fixed clamping of the overhead wire so that it can be towed to the designated position for maintenance.

[0061] In addition, during the traction process of the overhead wire, a section of the overhead wire away from the traction wheel 53 will fall. After the overhead wire is clamped by the clamping bending plate 54 and the clamping plate 57, the moving wheel 26 continues to drive the overhead wire to move toward the side where the overhead wire is dropped. During the movement, the overhead wire is straightened, which is convenient for staff to maintain when reaching the place where the overhead wire is dropped, thereby realizing the maintenance of the dropped overhead wire. There is no need for manual traction of the overhead wire, which can prevent the overhead wire from falling during the traction process, and the overhead wire can be straightened while being pulled, which is convenient for staff to maintain.

[0062] In addition, the present invention also provides a method for using auxiliary equipment for maintaining power towers, comprising the following steps: S1, installing the equipment: first, pulling the bidirectional telescopic rod 11 so that the moving device 2 is aligned with the overhead wire, which can be applied to overhead wires of various intervals, greatly improving the scope of application of the equipment; hanging the equipment on the overhead wires between the towers, and then adjusting the unidirectional telescopic rod 13 so that the length of the unidirectional telescopic rod 13 matches the height of the staff, so as to facilitate the staff to perform subsequent maintenance on the overhead wires above.

[0063] S2. Mobile maintenance: After the staff sits on the balance box 1, the gyroscope 21 is started to prevent the equipment from tilting in strong winds or when the staff leans sideways during the maintenance of the overhead wires, causing the staff to fall from the balance box 1, thereby greatly improving the safety of the equipment; then the drive motor 28 is started, and the output shaft of the drive motor 28 drives the multiple drive shafts 25 and the moving wheels 26 to rotate through the belt drive. During the rotation of the multiple moving wheels 26, the friction between the balance box 1 and the overhead wire drives the staff to move, and the staff patrols and maintains the overhead wires during the movement.

[0064] S3. Moving over obstacles: During the movement, when the trigger rod 304 contacts the shock-proof hammer, the trigger rod 304 rotates toward the side close to the moving wheel 26 under the obstruction of the shock-proof hammer, and drives the linkage rod 303 to move toward the side close to the moving wheel 26. The linkage rod 303 pushes the rotating wheel bracket 302 to move synchronously. The rotating wheel bracket 302 rotates at the hinge with the cross bar 22, and drives the moving wheel 26 to gradually move upward. The transmission shaft 25 slides along the sliding groove 24, and at the same time the linkage rod 303 and the vertical rod 301 rotate to a nearly horizontal state. Therefore, when the moving wheel 26 close to the shock-proof hammer moves above the shock-proof hammer, the linkage rod 303, the vertical rod 301 and the moving wheel 26 will not collide with the shock-proof hammer, and continue to move forward to cross the shock-proof hammer. Subsequently, the torsion spring drives the vertical rod 301 and the rotating wheel bracket 302 to rotate and reset, and the rotating wheel bracket 302 drives the moving wheel 26 to move downward and reset, so that the V-shaped groove 27 is again stuck in the overhead wire and continues to drive the equipment to move forward.

[0065] S4. Maintenance self-locking: When it is necessary to stop moving, turn off the drive motor 28, and then pull the lifting rod 41 downward. The lifting rod 41 drives the pull rod 40 to rotate along the support shaft 39, and the pull rod 40 rotates upward near the locking block 33, and drives the locking block 33 to move upward. The reset spring 37 adaptively retracts and contracts, and then the upper end of the locking block 33 contacts the overhead wire, thereby squeezing the overhead wire and increasing the friction force through the oblique groove 34. At the same time, the clamping block 35 is clamped into the clamping groove 31, and the moving wheel 26 cannot rotate under the limit of the clamping block 35, so that the equipment is fixed when the overhead wire needs to be maintained; when the maintenance is completed, release the lifting rod 41, the reset spring 37 adaptively contracts, and drives the locking block 33 to move downward, and the locking block 33 drives the pull rod 40 to rotate and reset.

[0066] In addition, the present application can also pull the overhead wires that have dropped out of service to complete the maintenance of the dropped out of service. Based on this, the maintenance steps for the dropped out of service are as follows:

[0067] First, adjust the one-way telescopic rod 13 near the side of the dropped line so that the moving wheel 26 is flush with the overhead wire that has not been dropped, thereby hanging the equipment on the upper end of the overhead wire, and then pull the clamping bending plate 54 near the side of the dropped line. The clamping bending plate 54 drives the telescopic end of the upper rotating wheel telescopic rod 52 to move upward, and drives the upper traction wheel 53 to move synchronously, and the support spring 55 shrinks adaptively to form a gap between the upper traction wheel 53 and the lower traction wheel 53, and then place the dropped overhead wire between the two traction wheels 53, loosen the clamping bending plate 54, and the support spring 55 rebounds to make the two traction wheels 53 fit each other, thereby clamping the overhead wire between the two traction wheels 53.

[0068] Start the drive motor 28, and the moving wheel 26 drives the equipment to move toward the tower where the line is disconnected. During the movement, the overhead wire that has been disconnected moves between the two traction wheels 53, and the traction wheel 53 rotates under the action of the friction force of the overhead wire. When the head of the overhead wire moves to the bottom of the traction wheel 53 on the side close to the moving direction of the equipment during the movement, the overhead wire moves out from between the traction wheels 53, and then the support spring 55 applies elastic force to the clamping bending plate 54, and the clamping bending plate 54 drives the telescopic end of the rotating wheel telescopic rod 52 to move toward the side close to the overhead wire. The two traction wheels 53 fit each other after losing the overhead wire, and at the same time, the two clamping bending plates 54 move synchronously with the traction wheel 53, and clamp the overhead wire to prevent the overhead wire from being detached from traction.

[0069] During the movement of the clamping and bending plates 54 towards each other, the clamping and bending plates 54 drive the trigger rod 56 to rotate along the rotating connection of the balance box 1. During the rotation of the trigger rod 56, the hinged rod 58 is driven to move toward the side close to the overhead wire. During the movement of the hinged rod 58, the clamping plate 57 is driven to rotate along the connection with the balance box 1, so that the two clamping plates 57 move away from one end of the hinged rod 58 and move toward each other, thereby further clamping the overhead wire to prevent the overhead wire from sliding out too quickly after separating from the traction wheel 53 and the clamping and bending plates 54 are not clamped in time. It should be noted that the opposite sides of the two clamping plates 57 gradually tilt toward the side close to the clamping and bending plates 54, so that the clamping plates 57 can increase the friction between the overhead wire and the overhead wire, and the friction is greater when the overhead wire falls on the side away from the moving direction of the equipment, thereby ensuring the fixed clamping of the overhead wire so that it can be towed to the designated position for maintenance.

[0070] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
