There are two lead screws 32, and the threads of the two lead screws 32 are opposite. The lead screw 32 is used to drive the slider 33 to move linearly along the inner wall of the box 4. The slider 33 is threadedly connected to the lead screw 32 and slides on the inner wall of the box 4.

[0023] One end of the slider 33 passes through the box 4 and is fixedly installed with a support frame 24. The support frame 24 is U-shaped and is used to support the installation of the mounting plate 27. The mounting plate 27 is fixedly installed on the inner wall of the support frame 24. The mounting plate 27 is used to support the rotation of the gear roller 25. The mounting plate 27 is vertically set and the gear roller 25 is rotatably connected to the mounting plate 27.

[0024] A third rack 21 is fixedly installed on the side wall of the guide rail body 1. The third rack 21 is vertically arranged and meshes with the gear roller 25. The arrangement of the third rack 21 is used to support the meshing connection of the gear roller 25.

[0031] The box 4 is square in shape and is set horizontally. The box 4 is set to support the installation of the dual-output shaft motor 31.

[0032] When workers need to climb upwards, they first align the gear rollers 25 on both sides with the side wall of the guide rail body 1, and then start the dual-output shaft motor 31. The dual-output shaft motor 31 drives the lead screws 32 on both sides to rotate. When the lead screws 32 on both sides rotate, since their threads are opposite, they will drive the sliders 33 on both sides to slide towards each other along the inner wall of the box 4. When the sliders 33 on both sides slide towards each other, they will drive the gear rollers 25 on both sides to move towards each other through the support frame 24 and the mounting plate 27 until the gear rollers 25 on both sides are inserted into the side wall of the guide rail body 1 and mesh with the third rack 21, thereby achieving the purpose of installing the fall protection device. The operation is simple and convenient, and when it is necessary to disassemble, simply rotate the dual-output shaft motor 31 in the opposite direction.

[0033] After the fall arrestor is installed, the safety rope 23 is tied to the worker. As the worker climbs upward, the safety rope 23, slip ring 29, slide bar 210, and support plate 28 will move the box 4 upward. As the box 4 moves upward, the slider 33, support frame 24, and mounting plate 27 will drive the gear roller 25 to rotate along the surface of the third rack 21. The gear roller 25 and third rack 21 also limit the movement of the box 4, facilitating its vertical movement. If the worker accidentally falls while climbing, the box 4 will be slowed down by the gear roller 25 and third rack 21, while the worker will fall freely under their own weight. During the fall, the safety rope will... 23 drives the slip ring 29 to slide onto the pull rope 211 and pulls the pull rope 211 to move. When the pull rope 211 is pulled, it will drive the squeezing block 217 to move. Under the limiting action of the second limiting rod 218, the squeezing block 217 will move vertically downward. When the squeezing block 217 moves vertically downward, it will squeeze the rollers 213 on both sides. After the rollers 213 on both sides are squeezed, they will drive the first limiting rod 214 to slide linearly along the through hole between it and the box 26 through the mounting bracket 212. The first limiting rods 214 on both sides will drive the first racks 216 on both sides to move in the opposite direction until the first racks 216 are inserted into the second racks 22 on the inner wall of the guide rail body 1, thereby achieving the purpose of fixing the box 26 and the box 4 and achieving the function of preventing fall.
