[0035] The safety rope of the safety belt passes through the middle part of the rope threading block 12, the rope threading groove 23 provided in the winding mechanism shell 21 and the inner side of the top of the two safety rope connecting mechanisms 3. When the worker wears the safety belt and needs to test the fixed position of the safety rope hook and the toughness of the safety rope, the worker moves the whole body to the middle section of the safety rope. At this time, the hydraulic push rod 14 is started, and the hydraulic push rod 14 starts to push the push rod 16 to move to the right, and moves to the right through the two tooth block connecting rods 15. The tooth blocks 17 arranged on the inner sides of the two tooth block connecting rods 15 engage the gear 34 at the bottom of the connecting plate 31, so that the gear rotating rod 35 rotates as a whole, and then drives the gear 34 at the top of the gear rotating rod 35 to rotate.

During the rolling process, one end of the safety rope is fixed to the position preset by the worker through a hook, and the other end is a safety belt worn on the worker. At this time, the two ends of the safety rope are gradually tightened. If the following conditions occur, the warning light 22 starts to alarm:

[0036] 1. The worker's safety belt is properly fastened, and the pulling force will loosen the safety belt as a whole;

[0037] 2. The position where the hook is hung is not firm, and the position where the hook is fixed by tension becomes loose;

The bottoms of the two groups of clamping plates 458 are fixedly connected with bolt connection blocks 459. The tops of the two groups of sliders 453 are fixedly connected with slider push rods 454.

The inner sides of the two moving plate push blocks 457 are respectively fixedly connected to the front and rear ends of the two-way hydraulic push rod 44.

[0041] When all the connections are confirmed to be safe, the worker will move the entire structure to the position where the safety rope hook is hung again. When reinforcement is needed, the worker will place the inner side of the two sets of clamps 458 on the outer wall of any position where the hook is hung, and the two-way hydraulic push rod 44 is started to push the two movable plates 455 to move outward. The two movable plates 455 move outward, thereby pushing the slider push rod 454 through the two sets of inclined slide grooves 456 to drive the slider 453 to slide inward on the outer wall of the outer slide groove rod 451, thereby making the two sets of clamps 458 move inward to clamp the two sets of clamps 458 at the fixed position, and then the personnel install bolts through the two sets of bolt connecting blocks 459 to further tighten the two sets of clamps 458, thereby ensuring that the reinforcement mechanism is firmly connected to the installed position. Through this design, when working at a height, even if the hook becomes loose, the reinforcement mechanism can provide secondary protection. In addition, the structural design of the reinforcement mechanism allows quick installation and disassembly, which is convenient for workers to quickly transfer between different work points, thereby improving work efficiency.

[0042] Working principle of the present invention: the safety rope of the safety belt passes through the middle part of the rope threading block 12, the rope threading groove 23 provided in the winding mechanism shell 21 and the inner side of the top of the two safety rope connecting mechanisms 3. When the worker wears the safety belt and needs to test the fixed position of the safety rope hook and the toughness of the safety rope, the worker moves the whole body to the middle section of the safety rope. At this time, the hydraulic push rod 14 is started, and the hydraulic push rod 14 starts to push the push rod 16 to move to the right, and moves to the right through the two tooth block connecting rods 15. The tooth blocks 17 arranged on the inner sides of the two tooth block connecting rods 15 engage the gear 34 at the bottom of the connecting plate 31, so that the gear rotating rod 35 rotates as a whole, and then drives the gear 34 at the top of the gear rotating rod 35 to rotate. The gear 34 at the top of the gear rotating rod 35 rotates and then engages the two sets of rack rods 37 to pull the expansion plate 36 to move inward, and the whole body is fixed to the outer wall of the middle section of the safety rope through the two sets of pulley connecting plates 38 and the inner pulley 39. Then the second motor 248 is started, and the second motor 248 starts After the drive turntable 2411 is started, the turntable 2411 rotates, and the arc-shaped slide groove 2412 at the bottom of the inner wall of the slide groove plate 2410 is pressed to make the columnar expansion rod 2414 slide along the turntable arc-shaped slide groove 2413 opened on the turntable 2411, so that the multiple columnar expansion rods 2414 are retracted inward to fix the safety rope, and then the motor 242 is started, and the motor 242 starts the transmission plate 243 to rotate, and the transmission plate 243 rotates to drive the second transmission plate 245 to rotate through the crawler 244. After the second transmission plate 245 rotates, it drives the rotating rod 246, the chute plate 2410 and the rotating plate 2411 for fixing the safety rope to rotate together, so that the safety rope is rolled up on the left inner wall of the winding mechanism housing 21 through the columnar expansion rod 2414. During the rolling process, one end of the safety rope is fixed to the position preset by the worker through a hook, and the other end is a safety belt worn on the worker. At this time, the two ends of the safety rope are gradually tightened. If the following conditions occur, the warning light 22 starts to alarm:

[0043] 1. The worker's safety belt is properly fastened, and the pulling force will loosen the safety belt as a whole;

[0044] 2. The position where the hook is hung is not firm, and the position where the hook is fixed by tension becomes loose;

[0045] 3. The safety rope has low toughness and breaks when subjected to tension;

[0046] When all the connections are confirmed to be safe, the workers will move the entire assembly to the position where the safety rope hook is hung again. When reinforcement is needed, the workers will place the inner sides of the two sets of clamps 458 on the outer wall of any position where the hook is hung, and the two-way hydraulic push rod 44 will be started to push the two movable plates 455 to move outward. The two movable plates 455 move outward, thereby pushing the slider against the slider rod 454 through the two sets of inclined slide grooves 456 to drive the slider 453 to slide inward on the outer wall of the outer slide groove rod 451, thereby making the two sets of clamps 458 move inward to clamp the two sets of clamps 458 at the fixed position, and then the two sets of bolt connecting blocks 459 are used by personnel to install bolts to further tighten the two sets of clamps 458, thereby ensuring that the reinforcement mechanism is firmly connected to the installed position.
