Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-altitude operation technology, and in particular to a safety rope adjustment device for high-altitude workers. Background Technology
[0002] Workers specialize in working at heights of 2 meters or more above the reference plane for fall height. Their work spans numerous fields, including construction, power engineering, telecommunications engineering, high-altitude cleaning, and bridge construction and maintenance. They bring benefits such as promoting urban development, ensuring infrastructure operation, enhancing building aesthetics and lifespan, and boosting economic development. Their work is widely applied in commerce, industry, and civil applications. Given the complexity and risks of high-altitude work scenarios, adjustable safety ropes are crucial. These ropes must be adaptable to different work scenarios (meeting the needs of height adjustment and position changes) and accommodate individual differences (considering the impact of body shape and equipment usage). By improving operational flexibility and safety (achieving flexible operation and dynamic safety assurance), they ensure the safety and work efficiency of workers at height.
[0003] The safety rope adjustment device for high-altitude workers generally consists of connecting components, length adjustment components, locking components, warning and auxiliary components, etc. The safety rope adjustment device is connected to the anchor point through the fixed buckle and the safety belt connecting buckle, and the length is adjusted by the ratchet or slider type adjustment buckle. It relies on the webbing buffer and elastic element for cushioning, and is locked by the locking device and safety lock to protect the safety of the workers.
[0004] Existing safety rope adjustment devices for high-altitude workers cannot achieve rapid donning of safety ropes. Before working at heights, workers need to spend extra time donning the safety rope, as complex connection and adjustment procedures can shorten the effective working time each day. For example, in large construction projects, if many workers are slow to don their safety ropes, the overall project progress will be affected. For high-altitude operations that require frequent changes in work locations or tasks, such as power maintenance personnel moving between different towers, the inability to quickly don the safety rope will prolong work intervals, affecting work continuity and reducing overall work efficiency. Therefore, a new safety rope adjustment device for high-altitude workers is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a safety rope adjustment device for high-altitude workers, which aims to improve the problem of not being able to quickly put on the safety rope in the existing technology.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A safety rope adjustment device for high-altitude workers includes a cable, an adjuster fixedly connected to one side of the cable, a hook fixedly connected to the end of the adjuster away from the cable, a safety rope one fixedly connected to the end of the hook away from the adjuster, a connecting block fixedly connected to the end of the safety rope one away from the hook, two sliding blocks slidably connected inside the connecting block, a spring fixedly connected inside each of the two sliding blocks, a fixing block slidably connected to the outside of the sliding blocks, a safety rope two fixedly connected to the other end of the fixing block, and a protective component for protecting the worker fixedly connected to the other end of the cable.

[0011] A limiting plate is slidably connected inside the hollow block, and one side of the limiting plate is rotatably connected inside the fixed disk;
[0012] As a further description of the above technical solution:
[0013] A clamping plate is fixedly connected to the other end of the limiting plate, and the bottom of the clamping plate is slidably connected to the top of the fixed plate.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 3 One embodiment of this utility model is a safety rope adjustment device for high-altitude workers, including a cable 1. The cable 1 can stably connect a fixed point at a high altitude to an adjustment device below, providing basic support for the entire safety protection device. An adjuster 2 is fixedly connected to one side of the cable 1. The adjuster 2 can flexibly adjust the effective length of the cable 1, so that the safety rope length can be appropriate when the worker is working at different heights.
[0033] The end of the adjuster 2 away from the cable 1 is fixedly connected to a hook 3. The hook 3 can be easily connected to the safety rope 4 and the connection is firm to prevent accidental detachment. The end of the hook 3 away from the adjuster 2 is fixedly connected to the safety rope 4. The safety rope 4 can be flexibly extended as the operator moves to ensure that the operator can move freely within a certain range. The outside of the safety rope 4 is fixedly connected to a button 11. Pressing the button 11 can control the operation of the cylinder 13 to control the key actions of the protective device. The end of the safety rope 4 away from the hook 3 is fixedly connected to a connecting block 5. The connecting block 5 is the hub connecting the safety rope 4 and the safety rope 10, so that the two work together.
[0034] The connecting block 5 has two sliding blocks 6 inside, which can slide within the connecting block 5 to provide an operational basis for connecting and separating the connecting block 5 from the fixing block 9. The outer side of the sliding block 6 is fixedly connected to a limiting block 8, which cooperates with the slot inside the fixing block 9 to securely lock the connecting block 5 and the fixing block 9. Both sliding blocks 6 are fixedly connected to a spring 7 inside, which can automatically reset the sliding block 6 after it is pressed, facilitating reconnection.
[0035] The outer side of the sliding block 6 is slidably connected to a fixing block 9. The fixing block 9 cooperates with the connecting block 5. By limiting the engagement of the locking block 8 with the slot, the stability of the connection between safety rope 1 4 and safety rope 2 10 is ensured. One side of the fixing block 9 is slidably connected to one side of the connecting block 5. This connection method allows the fixing block 9 and the connecting block 5 to be flexibly connected and separated, while ensuring the integrity of the connection. The fixing block 9 has a slot inside, which is precisely matched with the limiting block 8 to ensure the reliability of the connection.
[0036] The outer side of the limiting block 8 is slidably connected to the inside of the slot. The limiting block 8 slides inside the slot, thereby changing the connection state between the connecting block 5 and the fixing block 9. The other end of the fixing block 9 is fixedly connected to a safety rope 10. The safety rope 10 and the safety rope 4 work together to wrap around the waist of the worker, providing reliable waist fixation protection. The other end of the cable 1 is fixedly connected to a protective component for protecting the worker.
[0037] Reference Figure 1 , Figure 2 , Figure 4 The protective assembly includes a fixed plate 12, which provides a support platform for a series of subsequent actions, ensuring the orderly operation of each component. The bottom of the rotating ring 15 is rotatably connected to the top of the fixed plate 12, and the rotating ring 15 can rotate flexibly around the top of the fixed plate 12 to control the opening and closing of the gaps in the fixed plate 12. The interior of the fixed plate 12 is provided with a sliding groove, which provides a track for the sliding of components such as the clamping plate 18, ensuring the accuracy of their movement. The outer side of the fixed plate 12 is fixedly connected to one side of the cable 1, so that the protective assembly is tightly connected to the cable 1 to form a complete safety protection system.
[0038] A cylinder 13 is rotatably connected to the top of the fixed plate 12. The cylinder 13 drives the linkage block 14 through its extension and retraction movement, thereby controlling the movement of parts such as the rotating ring 15. The drive end of the cylinder 13 is rotatably connected to the linkage block 14. Under the drive of the cylinder 13, the linkage block 14 drives the rotating ring 15 to move, realizing the linkage between the parts. The rotating ring 15 is fixedly connected to the outside of the linkage block 14. The rotating ring 15 rotates with the movement of the linkage block 14, performing operations such as blocking the gaps in the fixed plate 12 and driving the hollow block 16.
[0039] Multiple hollow blocks 16 are rotatably connected inside the rotating ring 15. Driven by the rotating ring 15, the hollow blocks 16 can adjust the position of the limiting plate 17 and the clamping plate 18. The limiting plate 17 is slidably connected inside the hollow block 16. The limiting plate 17 slides inside the hollow block 16 and can precisely control the movement of the clamping plate 18 according to the rotation of the rotating ring 15. The other end of the limiting plate 17 is fixedly connected to the clamping plate 18. Driven by the limiting plate 17, the clamping plate 18 can clamp or loosen the steel wire to ensure that the operator does not fall accidentally.
[0040] The outer side of the clamping plate 18 is slidably connected to the inner side of the rotating ring 15. The sliding of the clamping plate 18 inside the rotating ring 15, combined with the sliding of its bottom on the top of the fixed plate 12, achieves effective clamping of the steel wire. The bottom of the clamping plate 18 is slidably connected to the top of the fixed plate 12. This connection method ensures the stability of the clamping plate 18 during operation, enabling it to reliably clamp the steel wire. One side of the limiting plate 17 is rotatably connected to the inside of the fixed plate 12, providing support and a rotational basis for the movement of the limiting plate 17, ensuring that it can accurately drive the clamping plate 18 to move.
[0041] Working principle: When workers need to work at height, they can simultaneously press the handles connected to the outside of the two sliding blocks 6 inside the connecting block 5. Pressing the handles moves the sliding blocks 6, causing them to slide inside the connecting block 5. The sliding block 6 is connected to a limiting block 8 on one side inside the fixed block 9. The fixed block 9 has a slot inside. The connecting block 5 and the fixed block 9 can be connected by the cooperation of the limiting block 8 and the slot. When the connection is released by pressing the sliding block 6, the fixed block 9 and the connecting block 5 can be opened. At this time, the worker can place the safety rope 1 4 and the safety rope 2 10 at the waist position, and then press the handle to make the sliding block 6 slide. After the sliding block 6 slides, it can be placed back inside the fixed block 9. When the handle is released, the sliding block 6 will be pushed back to its original position by the compressed spring 7, because the two sides of the spring 7 are fixed to the inside of the two sliding blocks 6 respectively.
[0042] After the worker connects safety rope 14 and safety rope 20 around their waist, they can align the gap inside the fixing plate 12 with the outside of the steel wire and slide the steel wire into the multiple clamps 18. At this point, the cylinder 13 can be controlled by pressing and holding button 11, causing the cylinder 13 to drive the linkage block 14. The outer side of the linkage block 14 is connected to a rotating ring 15. When the linkage block 14 moves, the rotating ring 15 will also rotate, thus blocking the gap in the fixing plate 12 and preventing the steel wire from accidentally falling out of the multiple clamps 18. The cylinder 13 slides out from inside the cylinder 8. When the worker reaches the designated height, the cylinder 13 can be controlled again by the button 11, so that the rotating ring 15 continues to rotate. The rotation of the rotating ring 15 drives the hollow block 16. The limiting plate 17 slides inside the hollow block 16. One side of the limiting plate 17 rotates inside the fixed plate 12, and the other end is connected to the clamping plate 18. So when the rotating ring 15 continues to rotate, multiple limiting plates 17 will drive the clamping plate 18 to rotate inward together, thereby clamping the steel wire through the clamping plate 18 to prevent the worker from falling accidentally during work.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
