Description

Technical Field

[0001] The present application relates to the technical field of power transmission and maintenance equipment, and in particular to auxiliary equipment for maintaining power towers. Background Art

[0002] Power towers and transmission cables are the main components of the power system. Power towers are used to support transmission cables, and transmission cables are used to transmit electricity. In order to ensure the continuity and reliability of power transmission, protect the ecological environment and optimize power network planning, circuit workers are often required to inspect transmission cables and power towers, and perform maintenance in a timely manner when problems are found.

[0003] At present, when repairing transmission cables, circuit workers need to climb to the corresponding power tower, then move along the transmission cable to the location that needs repair, and then take out the repair tools they carry with them to repair the corresponding location. In this process, circuit workers need to consume a lot of physical strength to climb the power tower, especially when they carry a lot of tools, they need to consume more physical strength, which will lead to low efficiency of subsequent maintenance work of circuit workers and great safety hazards.

[0004] In order to assist circuit workers in repairing transmission cables, existing auxiliary equipment for power tower maintenance includes a tower climbing device, which can automatically climb to the power tower through a manipulator, and the climbing device is additionally provided with a storage box, so that maintenance tools can be loaded through the storage box. The tower climbing device can carry the tools needed by the circuit workers to the power tower, which can reduce the weight of the circuit workers and thus reduce the physical strength consumed by the circuit workers.

[0005] Since the existing tower climbing device mainly uses a mechanical arm for climbing, the climbing device needs to be close to the surface of the power tower. However, there are many steel frame structures on the surface of the power tower, which can easily cause some of the steel frame structures to interfere with the tower climbing device, thereby causing the tower climbing device to be unable to climb, or even causing the tower climbing device to fall due to an unstable connection with the power tower. Summary of the invention

[0006] The present application provides an auxiliary equipment for power tower maintenance, the purpose of which is to reduce the structural requirements of the power tower for the auxiliary equipment, so that the auxiliary equipment can climb on different power towers, making it easier to carry the tools needed by circuit workers to the power tower.

[0007] The auxiliary equipment for power tower maintenance provided in this application adopts the following technical solution:

[0008] An auxiliary device for maintaining an electric power tower comprises a climbing body, on which a carrying mechanism for fixing maintenance tools is provided; a rope climbing machine, which is arranged on the climbing body and is used to drive the climbing body to rise and fall along an auxiliary rope; and a strong magnetic fixing mechanism, which comprises a strong electromagnet and a strong magnetic driving member, the strong electromagnet being located on a side of the climbing body away from the rope climbing machine, the strong magnetic driving member being located between the strong electromagnet and the climbing body, and the strong magnetic driving member being used to drive the strong electromagnet to move closer to or away from the climbing body.

[0009] By adopting the above technical solution, firstly, the setting of the carrying mechanism on the climbing body ensures that the auxiliary equipment can carry tools and provide maintenance tools for circuit workers. As for the setting of the rope climbing machine, by pre-installing auxiliary ropes on the power tower or on the transmission cables near the power tower, the auxiliary ropes are passed through the rope climbing machine. Under the action of the rope climbing machine, the climbing body can move along the auxiliary ropes, thereby realizing the climbing function. The auxiliary ropes are spaced apart from the outer wall of the power tower, which can ensure that the climbing body does not contact the outer wall of the power tower, thereby reducing the interference of the power tower on the climbing of the auxiliary equipment.

[0010] On this basis, the setting of the strong magnetic fixing mechanism can drive the strong electromagnet to move toward the power tower through the strong magnetic driving part, and then the strong electromagnet is adsorbed with the power tower to fix the auxiliary equipment. Since the auxiliary rope is used as the support for climbing, the auxiliary rope is greatly affected by environmental factors and is prone to shaking. When the shaking is large and the auxiliary equipment cannot be climbed temporarily, the strong magnetic fixing mechanism can fix the auxiliary equipment to ensure the safety of the auxiliary equipment and the safety of the circuit workers on the lower side of the power tower.

[0011] The setting of the rope climbing mechanism and the strong magnetic fixing mechanism reduces the structural requirements of the auxiliary equipment on the power tower while ensuring the safety of the auxiliary equipment, so that the auxiliary equipment can climb on different power towers, thereby increasing the applicability of the auxiliary equipment.

[0012] Optionally, a plurality of the strong magnetic fixing mechanisms are provided, and the plurality of the strong magnetic fixing mechanisms are arranged in sequence and at intervals along the length direction of the climbing body; the strong magnetic driving component and the strong electromagnet are both slidably connected with the climbing body along the length direction of the climbing body, and a plurality of return springs are arranged between the strong magnetic driving component and the climbing body, and the length direction of the return spring is arranged along the length direction of the climbing body, and one end of the return spring is connected to the strong magnetic driving component, and the other end is connected to the climbing body.

[0013] By adopting the above technical solution, since the strong magnetic drive and the strong electromagnet are both slidably connected to the climbing body, when the strong electromagnet is adsorbed to the power tower, the corresponding strong electromagnet is fixed, and the climbing body can still rise under the action of the rope climbing machine. Based on this principle and the cooperation of the reset spring, after the climbing body rises into place, the adsorption of the strong electromagnet and the power tower is released, and at this time, under the action of the reset spring, the position of the strong electromagnet and the strong magnetic drive is reset. Therefore, with the setting of such a strong magnetic fixing mechanism, when the auxiliary equipment climbs on the power tower, the strong electromagnet is adsorbed on the power tower, but it does not affect the climbing of the auxiliary equipment, which can increase the stability and safety of the climbing of the auxiliary equipment.

[0014] Since several strong magnetic fixing mechanisms are provided, they are used alternately in sequence, which ensures that during the climbing process of the auxiliary equipment, there are always strong electromagnets adsorbed on the power tower, which can ensure the stability and safety of the auxiliary equipment during the entire climbing process.

[0015] Optionally, it also includes two crawler transmission mechanisms, which are located on the side of the climbing body away from the rope climbing machine, and the two crawler transmission mechanisms are spaced apart along the width direction of the climbing body; the crawler transmission mechanism includes a magnetic crawler and two driving wheels, the two driving wheels are spaced apart along the length direction of the climbing body, the driving wheels are rotatably connected to the climbing body, the driving wheels are coaxially connected with a crawler driving member for driving their own rotation, the magnetic crawler is sleeved on the outside of the two driving wheels, and the driving wheels are transmission-connected to the magnetic crawler.

[0016] By adopting the above technical solution, the crawler transmission mechanism places the auxiliary equipment on the outside of the power tower through the cooperation of the driving wheel, the crawler drive and the magnetic crawler, and the magnetic crawler adsorbs the auxiliary equipment on the power tower. At this time, under the drive of the crawler drive, the driving wheel cooperates with the magnetic crawler, and the auxiliary equipment climbs on the power tower. The setting of the crawler transmission mechanism, on the one hand, when the surface of the power tower is relatively flat, it can directly climb to the outside of the power tower through the crawler transmission mechanism; on the other hand, when using a rope climbing machine to climb the auxiliary equipment, the magnetic crawler can be adsorbed on the outside of the power tower, and the rope climbing machine can be assisted to climb the auxiliary equipment, reducing the impact of the shaking of the auxiliary rope on the climbing of the auxiliary equipment.

[0017] Optionally, a plurality of permanent magnets are arranged on the magnetic track, and the plurality of permanent magnets are arranged in sequence and at intervals along the length direction of the magnetic track.

[0018] By adopting the above technical solution, the setting of the permanent magnet provides a magnetic source for the magnetic track, meeting the working requirements of the magnetic track.

[0019] Optionally, a plurality of reinforcing electromagnets are also provided on the magnetic track, and the plurality of reinforcing electromagnets are arranged in sequence and at intervals along the length direction of the magnetic track.

[0020] By adopting the above technical solution and reinforcing the electromagnet, when it is necessary to enhance the adsorption force between the magnetic track and the power tower, the magnetic force of the reinforcing electromagnet can be controlled by energizing the reinforcing electromagnet and controlling the current, thereby changing the adsorption force between the magnetic track and the power tower.

[0021] Optionally, a scraping assembly is provided on the climbing body, and the scraping assembly includes a flexible scraping plate, which is connected to the climbing body, and the length direction of the flexible scraping plate is arranged along the width direction of the magnetic track, and one side of the flexible scraping plate in the width direction is in contact with the outer wall of the magnetic track.

[0022] By adopting the above technical solution, the scraping assembly is equipped with a flexible scraping plate, so that during the use of the magnetic track, the flexible scraping plate can scrape off the iron powder or magnetic powder adsorbed on the outer wall of the magnetic track. This can prevent excessive iron powder or magnetic powder adsorbed on the outer wall of the magnetic track from affecting the stability of the adsorption between the magnetic track and the power tower.

[0023] Optionally, the strong magnetic fixing mechanism further includes a mounting frame, which is sleeved on the outer side of the corresponding strong electromagnet, and a laser sensor and a pressure sensor are provided on the side of the mounting frame facing away from the rope climbing machine.

[0024] By adopting the above technical solution, the installation frame is set up so that the laser sensor and the pressure sensor can be installed on the strong electromagnet. The setting of the laser sensor can detect the distance between the strong electromagnet and the outer wall of the power tower, ensuring that when the strong magnetic drive drives the strong electromagnet, the strong electromagnet can be stably adsorbed on the outside of the power tower. The setting of the pressure sensor can detect whether the strong electromagnet and the power tower are adsorbed in place. Therefore, the coordinated setting of the laser sensor and the pressure sensor is used to detect the adsorption of the strong electromagnet and the power tower.

[0025] Optionally, a plurality of cameras are provided on the climbing body.

[0026] By adopting the above technical solution and the setting of the camera, the auxiliary equipment of the present application can not only carry tools but also realize automatic inspection of power towers.

[0027] Optionally, several climbing bodies are arranged on the climbing body, and the climbing bodies are arranged in sequence along the length direction of the climbing bodies, and two adjacent climbing bodies are detachably connected.

[0028] By adopting the above technical solution, since a plurality of climbing bodies are provided and two adjacent climbing bodies are detachable, the length of the auxiliary device can be freely extended, thereby increasing the load capacity of the auxiliary device, thereby enabling the auxiliary device to carry more tools.

[0029] Optionally, two adjacent climbing bodies are rotationally connected.

[0030] By adopting the above technical solution, since two adjacent climbing bodies are rotatably connected, this enables a number of climbing rope bodies to pass smoothly when there are uneven areas on the power tower.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. The auxiliary equipment of the present application can carry tools to climb onto the power tower, thereby reducing the physical exertion of circuit workers, and with the cooperation of the climbing rope mechanism and the strong magnetic fixing mechanism, it can ensure the safety of the auxiliary equipment climbing on the power tower, while reducing the structural requirements of the auxiliary equipment on the power tower and improving the scope of application of the auxiliary equipment.

[0033] 2. The present application uses the cooperation of several strong magnetic fixing mechanisms, which enables the auxiliary equipment to be used alternately in the process of climbing the power tower. This ensures that there are always strong electromagnets adsorbed on the power tower, which can ensure the stability and safety of the auxiliary equipment during the entire climbing process.

[0034] 3. Through the provision of a crawler transmission mechanism, the auxiliary equipment of the present application can freely choose to climb on the power tower through a rope climbing machine and / or a crawler transmission mechanism, which can improve the scope of application of the auxiliary equipment.

[0049] Reference Figure 1 The carrying mechanism 2 includes a storage box 21, and the storage box 21 is fixedly connected to the climbing body 1. The opening of the storage box 21 is located on the side of the storage box 21 facing the rope climbing machine 4. The storage box 21 is detachably connected with a sealing plate 22, and the sealing plate 22 closes the opening of the storage box 21. In this embodiment, the sealing plate 22 is connected to the storage box 21 by bolts or locks. Through the setting of the storage box 21, the storage function can be realized, and then the storage of tools can be realized; and the setting of the detachable connection between the sealing plate 22 and the storage box 21 makes it convenient for circuit workers to take the tools in the storage box 21.

A hook threaded hole 24 is provided on the lower side of the convenient block 23. The convenient block 23 is provided to facilitate the circuit worker to hold the convenient block 23 to open the sealing plate 22; and the hook threaded hole 24 on the convenient block 23 allows the hook to be installed through the hook threaded hole 24, and then the transmission cable or other large-volume tools can be hung through the hook.

[0051] Reference Figure 1 There are four cameras 3, two of which form a group. Each storage box 21 is provided with a corresponding group of cameras 3. Each group of cameras 3 is located on the side of the corresponding storage box 21 away from the climbing body 1, and the two cameras 3 in the same group are arranged at intervals along the length direction of the climbing body 1.

The magnetic crawler 53 is sleeved on the outer sides of the two driving wheels 51 and the plurality of intermediate wheels 52, the driving wheels 51 are transmission-connected with the magnetic crawler 53, and the outer sides of the plurality of intermediate wheels 52 all contact the inner side wall of the magnetic crawler 53. There are two crawler driving members 54, which are arranged one by one with the driving wheels 51, and the driving shaft of the crawler driving member 54 is coaxially connected with the corresponding driving wheel 51. In this embodiment, the crawler driving member 54 adopts a motor.

[0054] The auxiliary equipment is placed outside the power tower, and the magnetic crawler 53 adsorbs the auxiliary equipment on the power tower. Under the drive of the crawler drive 54, the driving wheel 51 rotates, and the auxiliary equipment moves vertically outside the power tower under the drive of the crawler transmission mechanism 5.

The plurality of permanent magnets 531 are arranged in coordination to provide magnetic force for the magnetic track 53, so that the magnetic track 53 can be adsorbed to the outside of the power tower.

[0056] In this embodiment, refer to Figure 3 , the magnetic track 53 is also provided with a plurality of reinforcing electromagnets 532, which are all arranged outside the magnetic track 53, and are arranged at intervals in sequence along the length direction of the magnetic track 53, and the plurality of reinforcing electromagnets 532 and the plurality of permanent magnets 531 are arranged alternately in sequence along the length direction of the magnetic track 53. By controlling the plurality of reinforcing electromagnets 532, the magnetic force of the reinforcing electromagnets 532 can be changed, and thus the adsorption force between the magnetic track 53 and the power tower can be changed.

[0057] A conductive component is also provided between the magnetic track 53 and the climbing body 1. The conductive component includes a conductive rod and two conductive rings. The two conductive rings are embedded in the inner side of the magnetic track 53. The outer wall of the conductive ring is fixedly connected to the inner wall of the magnetic track 53.

A plurality of reinforcing electromagnets 532 are electrically connected to the two conductive rings. The length direction of the conductive rod is arranged along the width direction of the magnetic track 53. One end of the conductive rod extends into the climbing body 1, and the conductive rod is electrically connected to the controller in the climbing body 1. The other end of the conductive rod extends into the magnetic track 53, and the two conductive rings are slidably connected to the conductive rod. The coordinated arrangement of the conductive component ensures that the plurality of reinforcing electromagnets 532 can be electrically connected to the controller in the climbing body 1, and can provide a stable power supply to the plurality of reinforcing electromagnets 532.

[0058] Reference Figure 3 and Figure 4 A protection box 6 is provided between the crawler transmission mechanism 5 and the climbing body 1, and the protection box 6 is fixedly connected to the climbing body 1 and the corresponding storage box 21.

The provision of the protection box 6 can protect the crawler transmission mechanism 5.

[0059] Reference Figure 3 and Figure 4 Two scraping assemblies 62 are arranged between the protective box 6 and the magnetic track 53 . The two scraping assemblies 62 are arranged at intervals along the length direction of the climbing body 1 , and the magnetic track 53 is located between the two scraping assemblies 62 .

[0060] Reference Figure 4 and Figure 5 The scraper assembly 62 further includes a rotating column 621 and a flexible scraper plate 622. The length direction of the rotating column 621 is arranged along the width direction of the magnetic track 53, and both ends of the rotating column 621 are connected to the inner wall of the protection box 6. The length direction of the flexible scraper plate 622 is arranged along the length direction of the rotating column 621. One side of the flexible scraper plate 622 in the width direction is fixedly connected to the outer wall of the rotating column 621, and the other side contacts the magnetic track 53.

[0061] During the use of the magnetic track 53, due to the arrangement of the permanent magnet 531 and the reinforcing electromagnet 532, some iron powder or magnetic powder will be adsorbed on the surface of the magnetic track 53. When there is too much iron powder or magnetic powder attached, the adsorption force between the magnetic track 53 and the power tower will be reduced. Therefore, by arranging the scraping assembly 62, during the use of the magnetic track 53, the flexible scraping plate 622 will automatically scrape off the iron powder or magnetic powder attached to the outer wall of the magnetic track 53.

In this embodiment, the scraping drive 623 uses a motor, and the scraping drive 623 drives the rotating column 621 to rotate.

[0063] The rotating column 621 is driven to rotate by the scraping driving member 623 , so that the flexible scraping plate 622 in contact with the magnetic track 53 can be switched, thereby ensuring the scraping effect of the magnetic track 53 .

[0064] Reference Figure 2 The auxiliary equipment also includes a strong magnetic fixing mechanism 7, two strong magnetic fixing mechanisms 7 are provided, and the strong magnetic fixing mechanism 7 is located between the two protection boxes 6 along the width direction of the climbing body 1. The two strong magnetic fixing mechanisms 7 are arranged at intervals along the length direction of the climbing body 1.

[0065] Reference Figure 6 The strong magnetic fixing mechanism 7 includes a strong electromagnet 71 and a strong magnetic driving component 72.

The strong magnetic driving component 72 is connected to the climbing body 1, and the driving end of the strong magnetic driving component 72 is connected to the strong electromagnet 71. In this embodiment, the strong magnetic driving component 72 adopts an electric push rod.

[0066] Driven by the strong magnetic drive member 72, the strong electromagnet 71 can move toward or away from the rope climbing machine 4. When the auxiliary device climbs the power tower, the strong electromagnet 71 can move close to or away from the power tower. When the strong electromagnet 71 is adsorbed on the power tower, it can provide stable support for the auxiliary device, thereby having the functions of preventing falling and shaking.

[0067] Reference Figure 6 and Figure 7The strong magnetic fixing mechanism 7 also includes a fixing box 73. A first slot 74 is provided on the side of the climbing body 1 away from the rope climbing machine 4. The length direction of the first slot 74 is arranged along the length direction of the climbing body 1, and the fixing box 73 is plugged and matched with the first slot 74.

The length direction of the return spring 75 is arranged along the length direction of the climbing body 1. One end of the return spring 75 is connected to the climbing body 1, and the other end is connected to the inner side wall of the first slot 74. When the fixing box 73 slides in the first slot 74, the plurality of return springs 75 will resist the fixing box 73 to reset.

[0068] Reference Figure 6 The opening of the fixed box 73 is located on the side of the fixed box 73 away from the rope climbing machine 4, and the strong electromagnet 71 is located on the side of the fixed box 73 away from the rope climbing machine 4. The strong magnetic drive member 72 is located in the fixed box 73, and the strong magnetic drive member 72 is connected to the inner wall of the fixed box 73.

[0069] Reference Figure 6 With such a structural arrangement, after the strong electromagnet 71 is adsorbed to the power tower, the rope climbing machine 4 and the crawler transmission mechanism 5 continue to drive the auxiliary equipment to rise. At this time, the fixed box 73 is fixed in position, the climbing body 1 rises, and the reset spring 75 is compressed; after climbing a certain distance, the strong electromagnet 71 is released from the adsorption of the power tower, and the reset spring 75 drives the fixed box 73 to reset, and the fixed box 73 moves upward to reset. During this process, the strong electromagnet 71 is adsorbed to the power tower, which can ensure the stability of the auxiliary equipment. Furthermore, during the climbing process of the auxiliary equipment, the two strong magnetic fixing mechanisms 7 work alternately in sequence, which ensures that one strong electromagnet 71 is always adsorbed to the power tower, which can ensure the stability of the auxiliary equipment during the entire climbing process.

[0070] Reference Figure 6 The strong magnetic fixing mechanism 7 also includes a mounting frame 76, which is sleeved on the outside of the strong electromagnet 71, and a laser sensor and a pressure sensor are arranged on the side of the mounting frame 76 away from the climbing body 1. The laser sensor is used to detect the distance between the strong electromagnet 71 and the power tower, and the detection data of the laser sensor is used to determine the extension length of the strong magnetic driving member 72 to ensure that the strong electromagnet 71 can be adsorbed to the outside of the power tower; and the pressure sensor is used to detect whether the strong electromagnet 71 is adsorbed to the power tower.

[0071] The implementation principle of the embodiment of the present application is: when it is necessary to maintain the transmission cables and other transmission equipment on the power tower, the auxiliary equipment carries the tools required for maintenance through the carrying mechanism 2, and then the auxiliary equipment climbs to the power tower through the rope climbing machine 4 and / or the crawler transmission mechanism 5. At this time, the power workers take out the tools in the carrying mechanism 2 to maintain the transmission cables and other transmission equipment.

[0072] In addition, during routine inspection and maintenance of the power tower, the auxiliary equipment climbs on the power tower through the rope climbing machine 4 and / or the crawler transmission mechanism 5. During this process, the auxiliary equipment realizes automatic inspection of the power tower through a number of cameras 3, which facilitates the rapid inspection of the equipment that needs maintenance on the power tower.

[0073] The auxiliary setting of the present application has the following three climbing modes: the first one is that the rope climbing machine 4 works and the crawler transmission mechanism 5 does not work. At this time, the auxiliary equipment is separated from the power tower, and this climbing mode is not affected by the external structure of the power tower. The second one is that the crawler transmission mechanism 5 works and the climbing machine does not work. At this time, the auxiliary equipment is adsorbed on the outside of the power tower, and the auxiliary equipment is less affected by the wind, but this climbing mode is affected by the external structure of the power tower. The third one is that the rope climbing machine 4 and the crawler transmission mechanism 5 work at the same time. At this time, the rope climbing machine 4 is the main one and the crawler transmission mechanism 5 is the auxiliary one. This can improve the stability of the auxiliary equipment and reduce the influence of the shaking of the auxiliary rope on the climbing of the auxiliary equipment.

[0074] During the climbing process of the auxiliary equipment, the two strong magnetic fixing mechanisms 7 work alternately in sequence. During this process, the auxiliary equipment is adsorbed on the power tower, which can ensure the stability of the climbing of the auxiliary equipment. At the same time, when the auxiliary equipment falls, the strong magnetic fixing mechanism 7 can fix the auxiliary equipment on the power tower, which can improve the safety of the use of the auxiliary equipment.

[0075] Embodiment 2: A power tower maintenance auxiliary device, referring to Figure 8 and Fig. 9 The difference between this embodiment and embodiment 1 is that: a plurality of climbing bodies 1 are arranged, and each climbing body 1 is provided with a carrying mechanism 2, a camera 3, a rope climbing machine 4, a crawler transmission mechanism 5 and a strong magnetic fixing mechanism 7. The plurality of climbing bodies 1 are arranged in sequence along their own length direction, and two adjacent climbing bodies 1 are detachably connected, and two adjacent climbing bodies 1 are rotatably connected.

[0076] Reference Fig. 9The climbing body 1 is provided with a multi-section connection mechanism 8, which includes a connection column 81 and a connection sleeve 82, which are arranged at intervals along the length direction of the climbing body 1, and the climbing body 1 is located between the connection column 81 and the connection sleeve 82, and the axial directions of the connection column 81 and the connection sleeve 82 are both arranged along the width direction of the climbing body 1, and one axial end of the connection column 81 is detachably connected to the climbing body 1, and one end of the connection sleeve 82 is detachably connected to the climbing body 1. In this embodiment, the connection column 81 and the connection sleeve 82 are both connected to the climbing body 1 by bolts.

[0077] Reference Figure 8 When two adjacent climbing bodies 1 are connected, the connecting column 81 is plugged into and matched with the connecting sleeve 82 of the other adjacent climbing body 1, and the connecting column 81 is rotatably connected to the corresponding connecting sleeve 82. Such a structural setting can realize a detachable connection and a rotatable connection between two adjacent climbing bodies 1.

[0078] Reference Fig. 9 A fixing plate 83 is rotatably arranged on the connecting sleeve 82, the fixing plate 83 is coaxially arranged with the connecting sleeve 82, and a plurality of first threaded holes 84 are penetrated through the fixing plate 83. A plurality of second threaded holes 85 are penetrated through one axial end of the connecting column 81.

[0079] Reference Figure 8 and Fig. 9 When two adjacent climbing bodies 1 are connected, the connecting sleeve 82 is plugged into the corresponding connecting column 81. At this time, the second threaded hole 85 on the connecting column 81 is correspondingly arranged with the first threaded hole 84 on the corresponding fixing plate 83, and the first threaded hole 84 is coaxially connected with the corresponding second threaded hole 85. Through the matching arrangement of the first threaded hole 84 and the second threaded hole 85, bolts are inserted into the corresponding first threaded hole 84 and the second threaded hole 85, so that the connection between the connecting column 81 and the corresponding fixing plate 83 can be achieved, which can improve the stability of the connection between the two adjacent climbing bodies 1.

[0080] The implementation principle of the embodiment of the present application is: through the setting of the multi-section connection mechanism 8, several climbing bodies 1 can be connected in sequence, which can freely extend the length of the auxiliary equipment, thereby increasing the load capacity of the auxiliary equipment, and thus enabling the auxiliary equipment to carry more tools; at the same time, there will be more cameras 3 on the auxiliary equipment, which can increase the patrol range of the auxiliary equipment, and thus speed up the patrol speed of the power tower. This can reduce the difficulty and danger of the work of circuit workers.
