[0021] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] refer to Figure 1-4 The utility model provides a technical solution: a high-stability electric maintenance ladder, comprising a base 1, wherein the upper end surface of the base 1 is fixedly connected to two support plates 3, and a slide groove 2 is provided on the opposite side of the two support plates 3. By setting the slide groove 2, the pulley 16 can be easily moved, so that the movable plate 10 can move more smoothly. The upper end surface of the support plate 3 is fixedly connected to a first cross plate 5, and the upper end surface of the first cross plate 5 is fixedly connected to a servo motor 6. By setting the servo motor 6, the threaded rod 7 can be driven to rotate, and the movable plate 10 can be driven to move up and down. The output end of the servo motor 6 passes through the side wall of the first cross plate 5 and is fixedly installed with a threaded rod 7. The end of the threaded rod 7 away from the servo motor 6 is rotatably connected to the upper end surface of the base 1, and the surface of the threaded rod 7 is threadedly connected to the movable plate 10, and both sides of the movable plate 10 are rotatably connected with pulleys 16.

[0023] The upper end surface of the base 1 is fixedly connected with a slide rod 4 . By setting the slide rod 4 , the moving direction of the movable plate 10 can be limited. The movable plate 10 is slidably connected on the surface of the slide rod 4 .

[0024] Among them, a plurality of support columns 11 are fixedly connected to the lower end surface of the base 1. By providing the support columns 11, the stability of the device can be improved when placed on the ground. A second cross plate 12 is fixedly connected to one side of the plurality of support columns 11.

[0025] The upper end surface of the second transverse plate 12 is fixedly connected with a hydraulic rod 14, and the surface of the hydraulic rod 14 passes through the side wall of the second transverse plate 12 and is fixedly connected with a roller 13. By providing the roller 13, the device can be conveniently moved.

[0026] Among them, the upper end surface of the movable plate 10 is fixedly connected with a guardrail 8. By setting the guardrail 8, maintenance personnel can be protected when they are working. A guardrail 9 is rotatably connected inside the guardrail 8. By setting the guardrail 9, the protectiveness of the guardrail 8 can be improved by the guardrail 9 when maintenance personnel use this device.

[0027] A limiting groove is provided in the guardrail 8, a limiting rod 15 is magnetically connected in the limiting groove, a through hole is provided in the guard rod 9, and the surface of the limiting rod 15 is slidably connected in the through hole.

[0028] The working principle of the utility model is as follows: when using the device, the roller 13 is lifted upward and separated from the ground through the contraction movement of the hydraulic rod 14, and the support column 11 is in contact with the ground to make it firmly on the ground. Then the limit rod 15 is pulled out from the protection rod 9 and the limit groove, and the protection rod 9 is rotated to facilitate the staff to enter the guardrail 8. At this time, the threaded rod 7 is driven to rotate through the operation of the servo motor 6, and the movable plate 10 is driven to move up and down, and the movable plate 10 is adjusted to a suitable height to facilitate the staff to carry out maintenance work. During the movement of the movable plate 10, the pulley 16 slides in the slide groove 2, making the movement of the movable plate 10 more convenient. After use, the roller 13 is driven downward to contact the ground through the stretching movement of the hydraulic rod 14, so that the support column 11 is separated from the ground, which is convenient for the staff to move it.
