[0047] The present application will be further described in detail below with reference to the accompanying drawings.

[0048] This application discloses a centipede ladder device for electric applications.

[0049] Reference Figures 1 to 4 The electric centipede ladder 3 equipment includes a mobile vehicle 1, a support device 2, a centipede ladder 3, a hook device 4, a support transmission device 5, and a winch 6.

[0050] Mobile vehicle 1 is a multi-wheeled vehicle capable of free movement, such as the four-wheeled vehicle shown in the figure. Mobile vehicle 1 is used to move the entire centipede ladder 3 equipment to the location where construction needs to be carried out.

[0051] Reference Figure 1 , Figure 4 and Figure 5 To improve the stability and anti-tipping performance of the mobile vehicle 1 when the centipede ladder 3 is erected, the mobile vehicle 1 is also equipped with four support legs 11. The four support legs 11 are located at the four corners of the mobile vehicle 1, thereby supporting and fixing the mobile vehicle 1 around its perimeter to improve the stability of the mobile vehicle 1 when the centipede ladder 3 is in operation. The support legs 11 include a support rod 111, a threaded rod 112, and a support plate 113. One end of the support rod 111 is detachably connected and fixed to the mobile vehicle 1. The threaded rod 112 is threadedly connected to the other end of the support rod 111. The support plate 113 is located at the bottom of the threaded rod 112 and is used for support. To improve the stability of the connection between the threaded rod 112 and the support rod 111, a locking nut 114 is also threadedly connected to the threaded rod 112. In use, the locking nut 114 is located between the support rod 111 and the support plate 113, and the locking nut 114 is pressed against the support rod 111.

[0052] In order to improve the stability and weight of the mobile vehicle 1 during operation, counterweights 12 can be installed on both sides of the mobile vehicle 1 to increase the weight of the entire mobile vehicle 1.

[0053] Reference Figure 1 , Figure 6 and Figure 7 The support device 2 is used to support the vertically operating centipede ladder 3, and the support device 2 can be installed on the mobile vehicle 1. Specifically, the support device 2 includes a support plate 21, a connecting pipe 22, an anti-rotation sleeve 23, and a compression spring 24.

[0054] The support plate 21 is detachably connected and fixed to the mobile vehicle 1. Specifically, the mobile vehicle 1 is fixed with a mounting component 25 for mounting the support plate 21. Connecting posts 251 are provided on both sides of the mounting component 25, and the two connecting posts 251 are coaxially arranged. Two vertically arranged fixing plates 26 are formed and fixed on the support plate 21. Each fixing plate 26 has an oblong hole. In use, the two fixing plates 26 are located on opposite sides of the mounting component 25, and the connecting posts 251 pass through the oblong holes of the fixing plates 26. A pin 27 is also provided on the mobile vehicle 1 to prevent the fixing plates 26 from rotating. In use, the pin 27 passes through the oblong holes and is fixed to the mounting component 25, with the pin 27 located within the oblong holes. During use, the pin 27 and connecting posts 251 prevent the fixing plates 26 from rotating on the mounting component 25, but the fixing plates 26 can move up and down, allowing the support device 2 to adapt to different ground heights.

[0055] To improve the stability between the two fixed plates 26, a reinforcing plate 28 is also provided on the two fixed plates 26. The reinforcing plate 28 is L-shaped, and the two fixed plates 26 are located inside the L-shaped reinforcing plate 28. The fixed plate 26 is located between the mounting part 25 and the reinforcing plate 28. The pin 27 passes through the reinforcing plate 28 to connect the reinforcing plate 28 and the fixed plate 26.

[0056] The connecting pipe 22 is installed and fixed at the bottom of the centipede ladder 3. The connecting pipe 22 is rotatably connected to the support plate 21. The anti-rotation sleeve 23 is sleeved on the connecting pipe 22. The top of the connecting pipe 22 is formed with a connecting plate 221. The compression spring 24 is also sleeved on the connecting pipe 22. The compression spring 24 is located between the connecting plate 221 and the anti-rotation sleeve 23. The two ends of the compression spring 24 abut against the connecting plate 221 and the anti-rotation sleeve 23 respectively.

[0057] When using the centipede ladder 3, when it needs to be adjusted from a horizontal to a vertical position, the anti-rotation sleeve 23 is manually moved towards the compression spring 24 so that the anti-rotation sleeve 23 will not affect the rotation of the connecting pipe 22 and the support plate 21. When the centipede ladder 3 is adjusted to a vertical position, the anti-rotation sleeve 23 is released so that it falls and abuts against the support plate 21. When the centipede ladder 3 is operating vertically, the anti-rotation sleeve 23 is always pressed against the support plate 21 under the elastic force of the compression spring 24 to prevent the centipede ladder 3 from tipping over due to the rotation of the connecting pipe 22 and the support plate 21.

[0058] Reference Figure 1 and Figure 8 The top of the centipede ladder 3 is detachably connected to a platform 7 for construction operations. When the centipede ladder 3 is set vertically, a working board is set on the platform 7 in the horizontal direction, and personnel can stand on the working board. The working board is surrounded by a protective railing for protection.

[0059] The centipede ladder 3 is assembled from multiple detachable and connectable centipede sections 31. Each centipede section 31 includes a centipede tube 311, foot pedals 312, foot treads 313, and fall arrestor rings 314. An automatic connection assembly is installed on the centipede tube 311; during use, adjacent centipede sections 31 are connected and secured using this assembly. Multiple round foot pedals 312 are evenly distributed across the centipede tubes 311. To reduce the risk of slipping off the edges of the foot pedals 312 when standing on them, limiting protrusions are provided at the edges of the foot pedals 312 away from the centipede tubes 311.

[0060] There are also multiple foot pedals 313, which are spaced apart between multiple foot tubes 312, so that when the person gets tired of stepping on the foot tubes 312 during the climb, they can stand on the foot pedals 313 to relieve the pressure. In addition, to improve the stability of the person standing, the foot pedals 313 are also provided with protective patterns.

[0061] There are multiple fall arrestor rings 314, and the number of fall arrestor rings 314 can be set according to the actual situation. Fall arrestor rings 314 are used to hook the safety belt on the climber's body during the process of climbing the centipede ladder 3, so as to improve the stability of the climber.

[0062] Reference Figure 1 , Figure 2 and Figure 9 The hook device 4 includes a hook 41, a first hook rope 42 and a second hook rope 43. The hook 41 is used to connect the first hook rope 42, the second hook rope 43 and the wire rope of the winch 6.

[0063] Both ends of the first hook rope 42 are hooked and fixedly connected to the hook and hanger 41 and the fall arrest ring 314 of the upper half of the centipede ladder 3, respectively. In order to facilitate the hooking of the first hook rope 42 and the fall arrest ring 314 of the upper half of the centipede ladder 3, a hook can be set on the first hook rope 42, and the hook can be used to hook and fix it to the fall arrest ring 314.

[0064] The two ends of the second hook rope 43 are respectively hooked and fixedly connected to the hook and hanger 41 and the anti-fall ring 314 of the lower half of the centipede ladder 3. In order to facilitate the hooking of the second hook rope 43 and the anti-fall ring 314 of the lower half of the centipede ladder 3, a hook can be set on the second hook rope 43, and the hook and hanger can be used to hook and fix it.

[0065] Furthermore, during use, the hook on the wire rope of the winch 6 is hooked and fixed to the hook and hanger 41.

[0066] Reference Figure 1 and Figure 9 The mobile vehicle 1 is also equipped with a support frame 9, which can be adjusted in position on the mobile vehicle 1 and has both horizontal and vertical placement options. Specifically, the top of the mobile vehicle 1 has a sliding plate 91 with a groove. A slider 92 is fixedly mounted on the support frame 9, located within the groove on the sliding plate 91, and can slide within the groove to adjust the position of the support frame 9 on the mobile vehicle 1. When the slider 92 slides to the side of the groove away from the centipede ladder 3, the support frame 9 is in a horizontal position, which is the retracted state. When the slider 92 slides to the side of the groove closer to the centipede ladder 3, the support frame 9 is in a vertical position, which is the working state.

[0067] Reference Figure 4 and Figure 9 In addition, the mobile vehicle 1 is equipped with two positioning tubes 93 and a positioning rod 94. The two positioning tubes 93 are located on both sides of the mobile vehicle 1. When the support frame 9 is in operation, the positioning rod 94 passes through the positioning tubes 93 and the support frame 9 to position the support frame 9 and fix the support frame 9 to the mobile vehicle 1 so that it does not move. This prevents the wire rope of the machine from pushing the support frame 9 to move during operation and improves the stability of the support frame 9 during operation.

[0068] Reference Figure 1 and Figure 9 The support transmission device 5 mainly serves to support and transmit the wire rope when the winch 6 lifts the hook and hangs the device 4 and the centipede ladder 3. The support transmission device 5 is installed and fixed on the support frame 9 on the mobile vehicle 1. The support transmission device 5 includes a support body 51, a first fixed pulley 52 and a second fixed pulley 53.

[0069] The support body 51 is a double S-shaped glass fiber reinforced insulation material, and the support body 51 is composed of two support columns that can be folded in half for storage. In use, the two support columns can be connected and fixed by bolts or other fixing components. The inside of the support body 51 is hollow, and the wire rope of the winch 6 passes through the inside of the support body 51.

[0070] The first fixed pulley 52 is installed at the bottom of the support body 51 and is located inside the support body 51. There are two first fixed pulleys 52, which are arranged opposite each other. The wire rope of the winch 6 is located between the two first fixed pulleys 52. When in use, the wire rope of the winch 6 is wound around the required first fixed pulley 52 according to the actual working conditions.

[0071] The second fixed pulley 53 is installed on the top of the support body 51 and is located inside the support body 51. There are two second fixed pulleys 53, which are arranged opposite each other. The wire rope of the winch 6 is wound around the outside of the two second fixed pulleys 53. During the process of lifting the centipede ladder 3, the wire rope gradually changes from being wound around the two second fixed pulleys 53 to being wound around the second fixed pulley 53 on the side away from the centipede ladder 3.

[0072] Reference Figure 1 In order to improve the stability of the support transmission device 5 during operation, the centipede ladder 3 also includes a windproof rope 81 and a plug 82. The plug 82 is inserted into the ground, and the two ends of the windproof rope 81 are fixedly connected to the top of the support transmission device 5 and the top of the plug 82, respectively, so as to improve the wind resistance and stability of the support transmission device 5.

[0073] When in use, the support device 2, centipede ladder 3, hook device 4, support transmission device 5, and platform 7 can all be disassembled and placed on the horizontally placed support frame 9. When in use again, the positioning rod 94 is inserted into the positioning tube 93 on the support frame 9 to position the support frame 9, so that the mobile vehicle 1 can move the entire centipede ladder 3 equipment.

[0074] During assembly, the support device 2, centipede ladder 3, hook device 4, support transmission device 5, and platform 7 are assembled first. Then, the winch 6 is started, and the winch 6 uses steel wire rope to pull up the entire centipede ladder 3.

[0075] Specifically, when the wire rope of the winch 6 pulls the hook device 4, the wire rope of the winch 6 is wound around the first fixed pulley 52 and the two second fixed pulleys 53 on the side away from the centipede ladder 3. When the centipede ladder 3 is raised to a certain height, the wire rope of the winch 6 is wound around the first fixed pulley 52 and the two second fixed pulleys 53 on the side away from the centipede ladder 3.

[0076] 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.
