The lower wall of the counterweight block 18 is in contact with the ground, and the upper contact piece 20 and the lower contact piece 21 are in contact.
[0026] Four vertical plates 9 are fixedly arranged on the upper wall of the movable plate 8. The vertical plates 9 are arranged through and rotatably connected with a rotating rod 10. Two vertical plates 9 on the same side form a group. The rotating rod 10 is located on the outer wall between each group of vertical plates 9 and is coaxially fixedly connected with a rotating roller 11. A measuring line 12 is wound around the left rotating roller 11, and a scale is marked on the measuring line 12. The scale is adjusted according to the height of the counterweight 18 and the height of the lower wall of the bottom plate 1 from the upper wall of the movable plate 8. A safety line 23 is wound around the right rotating roller 11. The safety line 23 can ensure the horizontality of the counterweight 18 during the falling process, and when the measuring line 12 is disconnected, the safety line 23 can prevent the counterweight 18 and its internal components from being damaged.
[0027] The measuring line 12 and the insurance line 23 are both set through the moving plate 8, and the four side walls of the moving plate 8 are rotatably provided with balls to facilitate the laying of the measuring line 12 and the insurance line 23. The lower ends of the measuring line 12 and the insurance line 23 are fixedly connected to the counterweight 18. The outer wall of the rotating rod 10 between the two sets of vertical plates 9 is sleeved and coaxially fixedly connected with a worm gear 13. The upper wall of the moving plate 8 is fixedly provided with a motor 15, and the rotating shaft of the motor 15 is coaxially fixedly connected with a worm 14, and the worm 14 is meshed with the worm gear 13.

The processor 17 is connected to the upper contact sheet 20 for communication, the alarm 16 is connected to the processor 17 for communication, and the motor 15 is connected to the processor 17 for communication. After detecting that the lower contact sheet 21 contacts the upper contact sheet 20, a signal is sent to the processor 17, and the processor 17 receives the signal and sends instructions to the alarm 16 and the motor 15.
