[0028] In this embodiment, by inserting the roller 8 into the interior of the first slide rail 4, pressing the switch 10 in the direction of the slide groove inside the first slide rail 4, and turning the switch 10 to cause the rotating wheel 11 to rotate and slide with the slide groove inside the first slide rail 4, and pressing the handle 6 to drive the damper 12 to move downward, so that it is stuck to the bottom end of the rotating wheel 11 and fixes it.

[0029] Example 2

[0030] like Figure 3 to Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the top end of the vertical beam 1 is embeddedly connected with the horizontal beam 2, the front side of the horizontal beam 2 is fixedly connected with the second slide rail 23, the interior of the second slide rail 23 is provided with a slide groove, the interior of the slide groove of the second slide rail 23 is slidably connected with a moving block 22, the outer side of the moving block 22 is sleeved with a lifting rod 21, the bottom end of the lifting rod 21 is rotatably connected with a mechanical arm 15, the bottom end of the mechanical arm 15 is rotatably connected with a hook 16, the interior of the hook 16 is provided with a slot, the interior of the lifter housing 5 is provided with a round hole, the interior of the round hole of the lifter housing 5 is slidably connected with a switch 10, the outer side of the switch 10 is sleeved with a ring 14, the left side of the switch 10 is fixedly connected with a fixing pin 13, and the fixing pin The two sides of 13 are fixedly connected with rotating wheels 11, the fixing pin 13 is rotatably connected inside the circular hole of the lifter housing 5, the rotating wheel 11 slides inside the slide groove of the first slide rail 4, the groove hole of the hook 16 is tightly set with a spring 20, the top of the spring 20 is tightly set with a partition 19, the top of the partition 19 is fixedly connected with a lifting rod 21, the left side of the lifting rod 21 is tightly set with a slide bar 17, the inside of the slide bar 17 is rotatably connected with a pulley 18, the pulley 18 is fitted with the hook 16, the front end of the beam 2 is tightly set with a ladder cage 3, the rear side of the ladder cage 3 is provided with a hole, the ladder cage 3 is tightly set with the beam 2, the outside of the switch 10 is provided with a thread, the inside of the damper 12 is provided with a notch, and the inside of the notch of the damper 12 is fitted with the rotating wheel 11.

[0031] In this embodiment, the safety rope is passed through the inside of the hook 16 and tightened downward. At this time, the safety rope squeezes the lifting rod 21 to slide downward, and the lifting rod 21 squeezes the partition 19 to slide downward. At this time, the pulley 18 on the left side of the lifting rod 21 slides downward, driving the sliding rod 17 inside the pulley 18 to tilt to the right and form a sealing ring with the hook 16, so that the safety rope will not slip out of the hook 16. When the construction workers land safely, they only need to lift the safety rope upward to pop out under the reaction of the spring 20.

[0032] The working principle of this utility model:

[0033] First, the staff passes the safety rope through the hook 16 and tightens the safety rope downwards. At this time, the safety rope squeezes the lifting rod 21 to slide downwards, and the lifting rod 21 squeezes the partition 19 to slide downwards. At this time, the pulley 18 on the left side of the lifting rod 21 slides downwards, driving the sliding rod 17 inside the pulley 18 to tilt to the right and form a sealing ring with the hook 16, so that the safety rope will not slip out of the hook 16.

[0034] The first step is to turn the switch 10 to unscrew the wheel 11 on the outer side of the first slide rail 4, and then turn the switch 10 to turn the wheel 11 to slide with the slide groove inside the first slide rail 4. The handle 6 is pressed to drive the damper 12 to move downward so that it is stuck to the bottom end of the wheel 11 and fixed. At this time, the staff needs to continue to climb up and release the handle 6. At the same time, the wheel 9 on the outer side of the lifter housing 5 slides on the outer side of the first slide rail 4. When it is necessary to stop the lifting, just press the handle 6, the damper 12 moves downward so that it is stuck to the bottom end of the wheel 11. When it is necessary to construct the crossbeam 2, it is necessary to pull the handle 6 while pulling the damper 12 upward to release the clamping of the wheel 11. The second step is to turn the switch 10 to screw the wheel 11 on the outer side of the 13 fixing pin out of the first slide rail 4. The two steps can be performed simultaneously to remove the lifter housing 5.

[0035] When the vertical beam 1 is not to be processed, the worker first lands safely and lifts the safety rope upwards. Under the reaction force of the spring 20 inside the hook 16, the partition 19 is pushed to squeeze the lifting rod 21 to slide upwards. The lifting rod 21 pushes the pulley 18 to slide to the left, so that the slide bar 17 rotates to the left, and a gap is generated inside the hook 16, so that the safety rope can be removed.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
