The sliding wheel under the rotating disk rotates in the sliding groove, and the rotating disk is rotated on the platform base through the movable pulling plate, thereby changing the angle of the telescopic ladder, so that maintenance personnel can climb the telescopic ladder through the steps to repair and inspect all the inner walls of the tower at a certain height on the platform base, thereby increasing the maintenance range of the maintenance personnel to the inside of the tower, and solving the problem that it is difficult to repair after a certain height on the maintenance platform.

The lower surface of the rotating disk 41 is rotatably connected to the upper surface of the platform base 1, and the driving motor 43 drives the screw rod 44 to rotate, and the moving plate 45 engaged with the screw rod 44 is moved accordingly. In the process of the moving plate 45 moving on the pulling plate 49, the moving plate 45 will squeeze the rotating block 46 connected to one end of the moving plate 45. Since the other end of the rotating block 46 is rotatably connected to the telescopic column 47, the telescopic column 47 is restricted by the positioning column 48 to only move up and down, so the rotating block 46 squeezed by the moving plate 45 will drive the telescopic column 47 to rise, and when the moving plate 45 is away from the positioning column 48, the telescopic column 47 descends, thereby achieving the effect of changing the slope of the rotating block 46.

The lower end of the pushed out tool box 55 will be lifted, thereby driving the rotating column 56 to rise, and the rising rotating column 56 will pull up the rotating rod 57, and the pulled up rotating rod 57 will also pull up the fixed block 58, and the pulled up fixed block 58 will protrude, and after the storage device 5 is put down, the fixed block 58 will be supported on the platform base 1 to fix the storage device 5.

[0019] Working principle:

[0020] When in use, the lifting device 4 is set, and the driving motor 43 is turned on, so that the driving motor 43 drives the screw rod 44 to rotate, and the moving plate 45 meshed with the screw rod 44 is moved. In the process of the moving plate 45 moving on the pulling plate 49, the moving plate 45 will squeeze the rotating block 46 connected to one end of the moving plate 45. Since the other end of the rotating block 46 is rotatably connected to the telescopic column 47, the telescopic column 47 is restricted by the positioning column 48 to only move up and down. Therefore, the rotating block 46 squeezed by the moving plate 45 will drive the telescopic column 47 to rise, and when the moving plate 45 is away from the positioning column 48, the telescopic column 47 will drop, thereby achieving the improvement. The effect of changing the slope of the rotating block 46 is that since a telescopic ladder 8 is fixed on the rotating block 46, the lifting device 4 can change the slope of the telescopic ladder 8 to reach a required height. The sliding wheel 3 below the rotating disk 41 rotates in the sliding groove 7, and the rotating disk 41 is rotated on the platform base 1 through the movable pulling plate 49, thereby changing the angle of the telescopic ladder 8, so that maintenance personnel can climb onto the telescopic ladder 8 through the steps 42 to repair and inspect all the inner walls of the tower at a certain height on the platform base 1, thereby increasing the scope of maintenance personnel's maintenance of the interior of the tower and solving the problem that it is difficult to repair after a certain height on the maintenance platform.

[0021] A storage device 5 is provided. Usually, most of the storage box 51 is below the upper surface of the platform base 1. Therefore, when in use, the handle 52 needs to be pulled to lift the storage box 51. The handle 52 drives the pulling block 53 to move, so that the sliding block 54 moves upward. The movable plate 510 cooperates with the pushing rod 511 on the sliding block 54 to push out the tool box 55. The tools hung on the hook 59 on the inner wall of the tool box 55 are also pushed out, which is convenient for maintenance personnel to select. The lower end of the pushed out tool box 55 will be lifted, thereby driving the rotating column 56 to rise. The rising rotating column 56 will pull up the rotating rod 57. The pulled up rotating rod 57 will also pull up the fixed block 58. The pulled up fixed block 58 will protrude. After the storage device 5 is put down, the fixed block 58 The storage device 5 is fixed by supporting it on the platform base 1, so that the storage device 5 can be fixed on the platform base 1, which is convenient for maintenance personnel to take maintenance tools and objects in the storage box 51. When the maintenance personnel arrive at the platform base 1 from the entrance 2, they can pull out the storage device 5 to quickly take tools without carrying a large number of tools. When the inner wall of the tower needs to be inspected, the storage device 5 is pulled up again and the handle 52 is released. Due to the gravity of the tool box 55, the sliding block 54 and the handle 52, the tool box 55 and the fixed block 58 will fit to the surface of the storage box 51. At this time, the fixed block 58 and the tool box 55 no longer block the storage device 5 from falling, and the damping slide rail 6 prevents the free fall of the storage device 5 from being too fast, causing damage to the storage device 5.

[0022] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
