Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of high-altitude operation safety equipment, and particularly relates to an automatic safety rope storage device. Background Art
[0002] During high-altitude operations, since the safety rope of the ordinary safety belt worn by the operator is too long, it is easy to trip when the person bypasses the safety rope; during the operation process, when storing the long safety rope, it will cause distraction and danger; before and after the high-altitude operation starts, the operator needs to climb without the safety hook fixed. At this time, the long safety rope will bring certain troubles to the hands, resulting in that when climbing to a high place, the hands cannot climb with all their strength. Therefore, the long safety rope increases the danger index of high-altitude operations and is an unsafe factor that cannot be ignored in high-altitude operations. Summary of the Utility Model
[0003] The purpose of the utility model is to solve the above problems and provide an automatic safety rope storage device.
[0004] To solve the above technical problems, the technical solution adopted by the utility model is:
[0005] An automatic safety rope storage device includes a safety rope, a safety rope hook and a standard safety belt. The safety rope hook is arranged at one end of the safety rope, and the standard safety belt is arranged at the other end of the safety rope. It further includes a fixed buckle, a plurality of movable buckles, a pull rope and a return force mechanism. A loop is arranged at the upper end of the movable buckle, and a fixed clip is connected to the lower end of the loop. The fixed buckle is fixedly arranged in the middle of the safety rope. The plurality of movable buckles are evenly clamped on the safety rope between the fixed buckle and the standard safety belt through the fixed clip. The return force mechanism is fixedly arranged on the standard safety belt. One end of the pull rope is fixedly arranged on the fixed buckle, and the other end sequentially passes through the loop at the upper end of the movable buckle and is connected to the return force mechanism.
[0006] Further, the return force mechanism includes an outer box, an inner box, a volute spring and a fixed shaft. The fixed shaft is fixedly arranged at the center of the outer box. The inner box is coaxially and movably arranged in the outer box. The volute spring is arranged inside the inner box, and its inner end is connected to the fixed shaft, and the outer end is connected to the inner wall of the inner box. One end of the pull rope passes through the outer box and is connected to the outer wall of the inner box.
[0007] Further, the length of the safety rope is greater than the length of the pull rope.
[0008] Further, the safety rope hook can also be any one of a waist buckle, a lock buckle and a chest lock.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] 1. By setting up the return mechanism, the utility model can automatically and real-time retract the long safety rope, freeing both hands and eliminating the safety hazards caused by the long safety rope.
[0011] 2. The utility model has a light structure, simple operation, low cost, and can be reused. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following further describes the utility model with reference to the drawings and embodiments.
[0018] As Figures 1-4 shown, a safety rope automatic retracting device includes a safety rope 2, a safety rope hook 3, and a standard safety belt 8. The safety rope hook 3 is provided at one end of the safety rope 2, and the standard safety belt 8 is provided at the other end of the safety rope 2. It further includes a fixed buckle 4, a plurality of movable buckles 5, a pulling rope 6, and a return mechanism 7. The upper end of the movable buckle 5 is provided with a loop, and a fixed clip is connected to the lower end of the loop. The fixed buckle 4 is fixedly provided in the middle of the safety rope 2. The plurality of movable buckles 5 are evenly clamped on the safety rope 2 between the fixed buckle 4 and the standard safety belt 8 through the fixed clip. The return mechanism 7 is fixedly provided on the standard safety belt 8. One end of the pulling rope 6 is fixedly provided on the fixed buckle 4, and the other end sequentially passes through the loop at the upper end of the movable buckle 5 and is connected to the return mechanism 7. The length of the safety rope 2 is greater than the length of the pulling rope 6.
[0019] The return mechanism 7 includes an outer box 9, an inner box 10, a volute spring 11 and a fixed shaft 12. The fixed shaft 12 is fixedly arranged at the center of the outer box 9. The inner box 10 is coaxially and movably arranged in the outer box 9. The volute spring 11 is arranged inside the inner box 10, and its inner end is connected to the fixed shaft 12, and the outer end is connected to the inner wall of the inner box 10. One end of the pull rope 6 passes through the outer box 9 and is connected to the outer wall of the inner box 10.
[0020] The safety rope hook 3 can also be any one of a waist buckle, a lock buckle, and a chest lock.
[0021] The working process of the present utility model:
[0022] When a worker is working at height, the standard safety belt 8 is worn on the body, and the other end of the safety rope 2 is installed on the safety rod 1 through the safety rope hook 3;
[0023] The volute spring 11 is in a loose winding state at the beginning. When the worker approaches the safety rod 1, the volute spring 11 rotates and tightens around the fixed shaft 12, driving the inner box 10 to rotate, pulling the pull rope 6 to wind around the outer side wall of the inner box 10. The pull rope 6 outside the return mechanism 7 shortens, pulling the fixed buckle 4 towards the standard safety belt 8. At this time, the safety rope 2 between the fixed buckle 4 and the standard safety belt 8 is in a slack state, and several intermediate movable buckles 5 lift and evenly fold the safety rope 2 to prevent the entire safety rope 2 from being dragged onto the working platform and avoid the risk of the worker tripping easily when bypassing the safety rope; when the worker is climbing, the long safety rope 2 can be automatically stored through the above process, without the need to distract and use both hands to pull the safety rope 2, improving the safety factor;
[0024] The volute spring 11 is in a tight winding state at the beginning. When the worker moves away from the safety rod 1, the fixed buckle 4 generates a pulling force on the pull rope 6, and the pull rope 6 wound around the outer side wall of the inner box 10 is pulled out. At the same time, it drives the inner box 10 to rotate in the reverse direction, causing the volute spring 11 to unwind in the reverse direction, and the pull rope 6 is stretched, and the safety rope 2 is straightened.
