[0036] Embodiment 2

[0037] Refer to Figure 1 and Figure 6 A novel ladder climbing device, the lifting mechanism includes a second rotating motor 16, a first transmission roller 17, a first helical gear 18, a second helical gear 19, a second rotating roller 20, a drum 21, a steel rope 22 and a storage box 23.

The first transmission roller 17 is rotationally connected to the first connecting frame 2. One end of the first transmission roller 17 is fixed with the first helical gear 18. One side of the first helical gear 18 is meshed and connected with the second helical gear 19. The inner side of the second helical gear 19 is fixed with the second rotating roller 20. The second rotating roller 20 is rotationally connected to the first connecting frame 2;

[0038] The lifting mechanism further includes a roller 21, a steel cable 22, a storage box 23 and a second limiting groove 24. Drums 21 are fixed to both ends of the second rotating roller 20. Steel cables 22 are wound around the outer sides of the two drums 21. One end of the first connecting frame 2 near the second rotating motor 16 is slidably connected with a storage box 23. Second limiting grooves 24 are provided on the inner sides of both sides of one end of the first connecting frame 2. The storage box 23 is slidably connected with the first connecting frame 2 through the second limiting grooves 24. The bottom ends of the two steel cables 22 are fixed to the storage box 23.

[0039] Through the design of the lifting mechanism, the tools can be quickly and accurately transported to the top of the stepladder, greatly reducing the time and physical consumption of workers in carrying tools, thus improving work efficiency. At the same time, using the lifting mechanism for tool transportation can greatly reduce the risks such as workers losing their balance and tools falling, ensuring the safety of workers.

[0040] A power source is arranged inside the first connecting plate 1. The power source is electrically connected to the first rotating motor 8 and the second rotating motor 16, and the power source supplies power to the first rotating motor 8 and the second rotating motor 16.

[0041] The using process of a novel stepladder device provided by the present utility model is as follows: When more workers or equipment need to be accommodated during climbing so that they can work simultaneously or in parallel, start the first rotating motor 8. The output end of the first rotating motor 8 drives the bidirectional threaded rod 9 to rotate, so that the sliding plates 10 threadedly connected to the bidirectional threaded rod 9 move towards the closer side to each other, so that the first limiting plates 11 fixed to the sliding plates 10 slide along the first limiting grooves 15. Since the sliding plates 10 are rotatably connected to the third connecting plates 12, the movement of the sliding plates 10 drives the third connecting plates 12 to move. Since the third connecting plates 12 are rotatably connected to the extension plates 13, and the extension plates 13 are slidably connected to the first connecting plate 1, the rotation of the third connecting plates 12 drives the extension plates 13 to move, so that the first connecting frame 2 fixed to the extension plates 13 moves along with the moving wheels at the top of the first connecting frame 2;

[0042] Through the moving mechanism, the stepladder device can accommodate more workers or equipment, allowing them to work simultaneously or in parallel, thus improving work efficiency. The design of lateral elongation enables the working platform of the stepladder to flexibly adapt to various working environments, enhancing its versatility and practicability;

[0043] When a worker at the top of the access ladder needs a tool at the bottom of the access ladder, the worker at the bottom puts the tool inside the storage box 23. The worker at the top of the access ladder starts the second rotation motor 16. The output end of the second rotation motor 16 drives the first transmission roller 17 to rotate, so that the first bevel gear 18 fixed to the first transmission roller 17 also rotates accordingly. Since the first bevel gear 18 is meshed with the second bevel gear 19, the rotation of the first bevel gear 18 drives the second bevel gear 19 to rotate, so that the second rotation roller 20 fixedly connected to the second bevel gear 19 also rotates. Also, since the second rotation roller 20 is fixedly connected to the drum 21, the rotation of the second rotation roller 20 drives the drum 21 to rotate, so that the steel rope 22 wound around the outside of the drum 21 is stored as the drum 21 rotates, and thus the storage box 23 fixed to the steel rope 22 is stored. The worker at the top of the access ladder can easily take the tool from the inside of the storage box 23;

[0044] Through the design of the lifting mechanism, the tool can be quickly and accurately transported to the top of the access ladder, greatly reducing the time and physical consumption of the worker in carrying the tool, thus improving work efficiency. At the same time, using the lifting mechanism for tool transportation can greatly reduce the risks such as the worker losing balance and the tool falling, ensuring the safety of the worker.
