The upper end of the pull rod 19 is rotationally connected to the middle of a hook plate 21, and the upper end of the pull rod 20 is rotationally connected to the middle of another hook plate 21. Two limit stop rods 22 are respectively mounted on the pull rod 19 and the pull rod 20, and the two limit stop rods 22 respectively hold the two The upper rear part of the hook plate 21 is blocked, and the rear parts of the two hook plates 21 are provided with hooks for hooking the ladder crossbar. Two flip motors 23 are respectively installed on the pull rod 19 and the pull rod 20. The two flip motors 23 are respectively connected to the two hook plates 21 in transmission. When the driving assembly drives the pull rod 19 to rise, the pull rod 20 is synchronously lowered; it also includes a plurality of track wheels 24, and a plurality of track wheels 24 are installed on the left and right sides of the frame 18. The plurality of track wheels 24 are respectively limited in rolling with the left and right vertical rods of the ladder; it also includes two horizontal frames 25, two wheel frames 26, four pulleys 27, four hanging rods 28 and four limit hooks 29, and the pull rod 19 and the pull rod 20 are both provided with Two pull rods 19 are arranged symmetrically on the left and right, and two pull rods 20 are arranged symmetrically on the left and right. A cross frame 25 is installed between the two pull rods 19 and the two pull rods 20. A wheel frame 26 is installed in the middle of the two cross frames 25. Two slide grooves are symmetrically arranged on the two wheel frames 26. The two slide grooves are arranged in an eight-shaped shape. Four pulleys 27 are respectively slide blocks and spring components are elastically installed in the four slide grooves of the two wheel frames 26. The wheel grooves of the four pulleys 27 are respectively in rolling contact with the ladder steel cables. Hanging rods 28 are installed on the sliders of the four pulleys 27. The lower ends of the four limit hooks 29 are respectively rotatably connected to the two cross frames 25.

[0040] The reciprocating motor 32 drives the four driving wheels 30 to rotate synchronously clockwise, thereby driving the two chains 31 to rotate synchronously clockwise. At this time, the two chains 31 drive the two pull rods 19 to descend synchronously, and at the same time drive the two pull rods 20 to rise synchronously; similarly, the reciprocating motor 32 drives the four driving wheels 30 to rotate synchronously counterclockwise, thereby driving the two chains 31 to rotate synchronously counterclockwise.
