Description

Technical Field

[0001] This application relates to the technical field of auxiliary tools for the maintenance of power transmission towers, and in particular to a high-altitude maintenance platform for power transmission towers with a lifting mechanism. Background Technology

[0002] High-altitude maintenance of power transmission towers refers to a series of inspections, maintenance, and repairs carried out on power transmission towers standing at high altitudes. Traditional maintenance usually involves maintenance personnel using professional climbing tools, such as foot straps and safety belts, to gradually climb up the tower to various locations that need maintenance. However, this method is labor-intensive and carries certain safety risks.

[0003] A search revealed Chinese patent application CN201921614501.3, which discloses a portable operating platform for power tower maintenance. The platform includes a load-bearing component, a support component, a guardrail, a suspension component, and a fixing component. The load-bearing component is composed of three plates linked together by hinges. The support component consists of two plates with grooves in the middle, fixed perpendicularly to both sides of the load-bearing component. A guardrail, consisting of support columns and a retractable grating, is connected to the upper end of the load-bearing component. The suspension component, consisting of wire ropes, lifting rings, hooks, and support blocks, suspends the load-bearing component. The fixing component, consisting of fixing pins and canvas straps, secures the entire operating platform to the power tower. This invention is detachable and foldable, making it convenient to carry and transport. Workers can stand on the platform to perform operations at heights, ensuring construction safety, reducing labor intensity, and improving work efficiency.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In actual use, although the platform is temporarily installed at high altitudes, once it is fixed to the tower, if height adjustments are needed, the entire platform must be disassembled and then reinstalled on the tower in a suitable location. The high-altitude environment itself is highly dangerous, and the process of disassembling and reinstalling the platform requires maintenance personnel to perform a series of complex operations at high altitudes, such as unfastening fixed components and moving heavy load-bearing components. During this process, even slight carelessness could lead to accidents such as personnel falling or tools dropping, greatly increasing safety hazards. Utility Model Content

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a high-altitude maintenance platform for power transmission towers with a lifting mechanism. For example... Figure 1-5As shown, it includes a linkage block 1, a guide groove 2 is provided on one side of the linkage block 1, and a lifting screw 3 is rotatably fitted on the inner wall of the guide groove 2.

[0025] Please see Figure 1 and Figure 4 Two cross grooves 13 are provided on one side of the linkage block 1. The inner walls of the two cross grooves 13 are slidably fitted with cross guide blocks 14 that cooperate with the drive block 4. When the metal sleeve 601 is in a fixed state and the linkage block 1 moves upward, its cross guide blocks 14 will guide and restrict it in the cross grooves 13, thereby improving the stability during the movement.

[0026] Please see Figure 1 A hollow opening 15 is provided on one side of the linkage block 1, and multiple anti-slip grooves 16 are provided on the upper side of the stepping platform 122. The hollow opening 15 can reduce the weight of the linkage block 1, and the anti-slip grooves 16 can improve the anti-slip level on the stepping platform 122.

[0027] The lifting screw 3 is threaded with a drive block 4 that slides with the guide groove 2. A top pressure plate 5 is fixedly connected to the lower side of the drive block 4, and a locking mechanism 6 is provided on one side of the drive block 4.

[0028] Please see Figure 3 The locking mechanism 6 includes two metal sleeves 601 fixedly connected to one side of the drive block 4, a protective block 602 rotatably fitted to one side of the inner wall of the metal sleeve 601, and a return spring 603 fixedly connected between the metal sleeve 601 and the protective block 602. Under normal conditions, the return spring 603 keeps the protective block 602 in its initial position. Then, by locking the metal sleeve 601 onto the corresponding iron tower, the return spring 603, under its reset action, blocks the opening of the metal sleeve 601, thus achieving protection. The entire platform can be locked and fixed by the metal sleeve 601.

[0029] A drive box 7 is provided on the upper side of the linkage block 1. The upper end of the lifting screw 3 is fixedly connected to the worm gear 8 located inside the drive box 7. A worm 9 that meshes with the worm gear 8 is rotatably fitted on one side of the inner wall of the drive box 7. A linkage box 10 that cooperates with the worm 9 is provided on one side of the drive box 7. An operating mechanism 11 that cooperates with the worm 9 is provided on the inner wall of the linkage box 10. A folding maintenance table assembly 12 is provided on one side of the linkage block 1.

[0030] Please see Figure 2The operating mechanism 11 includes a large gear 111 fixedly connected to one end of the worm gear 9 and located inside the linkage box 10, an operating rod 112 rotatably engaged with one side of the inner wall of the linkage box 10, a small gear 113 fixedly connected to the operating rod 112 and meshing with the large gear 111, and a folding handle 114 fixedly connected to one side of the operating rod 112. By holding the folding handle 114, the operating rod 112 is rotated, and the small gear 113 on the operating rod 112 drives the large gear 111 accordingly. Through the gear transmission ratio, the operation can be made more labor-saving to a certain extent.

[0031] Please see Figure 1 The folding maintenance bench assembly 12 includes two fixed frames 121 fixedly connected to one side of the linkage block 1, a foot platform 122 rotatably engaged with the two fixed frames 121 on the adjacent side, and a limiting plate 123 fixedly connected to the lower side of the foot platform 122. The limiting plate 123 is in contact with the linkage block 1. When the foot platform 122 rotates around the fixed frame 121, its limiting plate 123 will abut against the lower side of the linkage block 1, thereby achieving a limit. When not in use, the foot platform 122 can be flipped to be horizontal with the linkage block 1, saving its space occupancy.

[0032] Please see Figure 1 The upper side of the stepping platform 122 is provided with a fixing groove 17. A magnetic block 18 is fixedly connected to the inner wall of the fixing groove 17. The magnetic block 18 cooperates with the linkage block 1. When the stepping platform 122 is folded, the fixing groove 17 and the linkage block 1 fit together. The internal magnetic block 18 can be used to temporarily fix the stepping platform 122.

[0033] The implementation principle of the high-altitude maintenance platform for power towers with a lifting mechanism in this application embodiment is as follows: When using a power tower that requires a long time for maintenance or repair, the metal sleeve 601 is put on the power tower pole, so that the drive block 4 is attached and fixed. The bottom has a top pressure plate 5 that abuts against other power tower poles. Temporary support can be provided by stepping on the stepping platform 122.

[0034] During use, if, after fixing, the operator is too short to reach higher areas for maintenance due to insufficient height or after repairing at a lower location, the operator can grasp the folding handle 114 on one side of the operating lever 112 and rotate the lever 112. This will cause the small gear 113 fixed to the operating lever 112 to rotate. Since the small gear 113 meshes with the large gear 111 fixedly connected to one end of the worm 9 and located inside the linkage box 10, the rotation of the small gear 113 drives the large gear 111 to rotate, which in turn drives the worm 9 to rotate. Inside the drive box 7, the worm 9 meshes with the worm wheel 8, and the rotation of the worm 9 will drive the worm wheel 8 to rotate synchronously. The upper end of the lifting screw 3 is fixedly connected to the worm wheel 8. When the worm gear 8 rotates, the lifting screw 3 will rotate on the inner wall of the guide groove 2 on one side of the linkage block 1. When the lifting screw 3 rotates, the drive block 4 will move up and down along the axial direction of the screw under the coordinated restriction of the guide groove 2, the cross groove 13, and the cross guide block 14, thereby pushing the linkage block 1 and the folding maintenance platform assembly 12 to move up and down, thus realizing the lifting function of the entire maintenance platform. This makes it easy to adjust the platform to a suitable maintenance height position on the power tower, eliminating the need for cumbersome disassembly and reinstallation to change the height as in the traditional method. This greatly improves the flexibility of maintenance work, allowing maintenance personnel to inspect and maintain the tower at various heights more efficiently.

[0035] During operation, by holding the folding handle 114, the operating lever 112 is rotated, which in turn drives the small gear 113 to rotate. The small gear 113 then drives the large gear 111 to rotate, which reduces the force required for operation and improves the ease of operation.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
