[0023] A conveyor belt 20 is provided on the conveyor 17. The outer side of the conveyor belt 20 is covered with a grid anti-slip pattern 21 to prevent the conveyor belt 20 from sliding during the process of lifting the wall panel.

[0024] A fixing block 14 is fixedly installed in the middle of the upper surface of the platform 6. One end of the cylinder bottom of the hydraulic telescopic rod 15 is hinged to the fixing block 14, and one end of the piston rod of the hydraulic telescopic rod 15 is fixedly connected to the connector 27. When the piston rod of the hydraulic telescopic rod 15 extends or retracts, it drives the conveyor 17 to rotate around the rotating shaft, thereby adjusting the tilt angle of the conveyor 17.

[0025] An installation groove 9 is provided on the upper surface of the platform 6 on the side of the fixed block 14 away from the U-shaped groove. A vertical installation hole 12 is provided on the bottom surface inside the installation groove 9. The installation hole 12 is connected to the lower surface of the platform 6.

[0026] A positioning head 13 is fixedly installed at the lower end of the telescopic ladder 1, and a positioning groove 10 is provided on the lower end face of the positioning head 13. The positioning head 13 is snapped into the mounting groove 9, and the positioning groove 10 corresponds to the mounting hole 12. The positioning shaft 11 passes upward through the mounting hole 12 and is screwed to the positioning head 13, thereby fixing the positioning head 13 to the platform 6. The threaded connection is not only stable and reliable, but also easy to operate, greatly improving the installation efficiency and ease of use of the telescopic ladder 1.

[0028] A control box 16 is fixedly installed on one side of the platform 6. The control module inside the control box 16 is electrically connected to the conveyor 17 and the hydraulic telescopic rod 15.

[0029] The working principle of this utility model is as follows: First, adjust the brake roller 19 to the unlocked state so that the brake roller 19 can rotate freely. Move the entire device to the side of the storage tank that needs to be inspected by using the brake roller 19. Then, adjust the brake roller 19 to the locked state so that the platform 6 will not move accidentally.

[0030] The first maintenance worker then climbs the telescopic ladder 1 to reach the location of the storage tank requiring maintenance. The second maintenance worker controls the hydraulic telescopic rod 15 to extend and retract, adjusting the tilt angle of the conveyor 17 so that the second discharge port moves to the side of the first maintenance worker. The wall panel is then placed inside the first discharge port. The wall panel inside the first discharge port moves along the lower outlet of the first discharge port to the lower end of the conveyor belt 20 of the conveyor 17. Under the action of the conveyor belt, the wall panel is lifted upwards and then falls into the second discharge port, exiting from the lower outlet of the second discharge port. The first maintenance worker removes the lifted wall panel from the lower outlet of the second discharge port and uses the removed wall panel to perform maintenance on the storage tank.
