Abstract
Description
Technical Field
[0001] This utility model relates to the field of hook technology, and in particular to a high-altitude fall-prevention self-locking hook structure. Background Technology
[0002] A hook is a common connecting and hanging tool, simple in structure yet widely used. It consists of a hook body and some auxiliary components, using its curved hook to hold objects, thus fixing or suspending them. In daily life, hooks can be used to hang clothes, kitchen utensils, etc.; in the industrial field, they can also be used for hoisting goods, bringing many conveniences to people's lives and work.
[0003] The high-altitude fall arrestor self-locking hook mainly consists of a hook body, a locking device, and connecting components. Its working principle is that the hook remains open for easy connection during normal use. If a worker falls, the change in speed triggers the locking device, which uses friction or mechanical engagement to quickly lock the safety rope, preventing further descent and ensuring safety during high-altitude operations.
[0004] In existing technologies, some self-locking hook structures cannot completely offset the huge impact force generated by a fall by relying solely on the initial locking friction force during use. This can lead to excessively long braking distances for workers and excessive impact forces on their bodies, thereby increasing the risk of injury or even endangering their lives. Therefore, a high-altitude fall protection self-locking hook structure is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a high-altitude fall arrest self-locking hook structure, which aims to improve the problem in the prior art that it is difficult to increase the friction of the steel cable during a fall, resulting in an excessively long braking distance.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A high-altitude fall arrestor self-locking hook structure includes a protective shell, a placement box fixedly connected to one end of the protective shell, two dampers fixedly connected inside the placement box, springs sleeved on the outside of the dampers, a metal block fixedly connected to the other end of the dampers, an electronic valve installed on the right side of the placement box, a friction stone fixedly connected to one end of the protective shell, an engagement groove opened on the end of the friction stone near the placement box, a rotating shaft rotatably connected inside the protective shell, a cable storage reel installed outside the rotating shaft, a detector fixedly connected inside the protective shell, a steel cable fixedly connected outside the cable storage reel, and a rotating assembly fixedly connected to one end of the steel cable.
[0008] As a further description of the above technical solution:
[0009] The rotating assembly includes a rotating block, the right end of which is fixedly connected to one side of the steel cable. A locking device is rotatably connected to the outside of the rotating block, and a connecting lock is engaged inside the locking device.
[0010] As a further description of the above technical solution:
[0011] The left side of the connecting lock is rotatably connected to a rotating column, and the left side of the rotating column is fixedly connected to a hook;
[0012] As a further description of the above technical solution:
[0013] A spring plate is fixedly connected to the outside of the rotating shaft, and the spring plate is made of high carbon steel;
[0014] As a further description of the above technical solution:
[0015] A cord is fixedly connected to the right end of the protective shell, and the cord is made of aramid fiber.
[0016] As a further description of the above technical solution:
[0017] The outer side of the steel cable is in contact with the inside of the locking groove, and the outer side of the steel cable is in contact with the end of the metal block near the friction stone;
[0018] As a further description of the above technical solution:
[0019] One end of the spring is fixedly connected to one side of the placement box, and the other end of the spring is fixedly connected to one side of the metal block.
[0020] As a further description of the above technical solution:
[0021] The end of the metal block near the friction stone is in contact with the end of the electronic valve near the damper, and the outside of the metal block is engaged inside the engagement groove.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, movement is achieved by opening the electronic valve. Since the damper and spring are in a taut state, they can push the metal block to move. This effectively reduces the huge impact force on the worker during the moment of falling and braking, reducing the risk of injury. Secondly, the smoother deceleration process helps maintain stability and prevents damage to components such as ropes or hooks due to excessive impact, further ensuring the safety of high-altitude operations.
[0024] 2. In this utility model, the hook can drive the rotating column to rotate inside the connecting lock during the rotation process. At the same time, after the connecting lock rotates, the steel cable will not get tangled because the rotating block can rotate inside the locking mechanism. When the spring plate contracts, the steel cable can be automatically contracted, which can adjust the length of the steel cable in time during operation, making the operator more flexible and reducing the risk of steel cable slack. When the operator rotates, the steel cable will not twist together, which can ensure that the steel cable is evenly stressed, avoid internal damage caused by twisting, and ensure the strength of the steel cable.

[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 3This utility model provides an embodiment of a high-altitude fall-prevention self-locking hook structure, comprising a protective shell 1, which serves as an installation base. A placement box 6 is fixedly connected to one end of the inner side of the protective shell 1, providing a support point. Two dampers 7 are fixedly connected inside the placement box 6, and the dampers 7 are telescopic. A spring 8 is sleeved on the outside of the dampers 7, generating potential energy. One end of the spring 8 is fixedly connected to one side of the placement box 6, providing a fixing function. A metal block 9 is fixedly connected to the other end of the dampers 7, and the other end of the spring 8 is fixedly connected to the metal block 9. On one side, since the spring 8 and damper 7 are in a taut state, they can drive the metal block 9 to move. An electronic valve 10 is installed on the right side of the placement box 6. When the electronic valve 10 is opened, the metal block 9 can be ejected by the damper 7 and spring 8. The end of the metal block 9 near the friction stone 11 contacts the end of the electronic valve 10 near the damper 7. The electronic valve 10 can hold the metal block 9 in place. The friction stone 11 is fixedly connected to one end of the inner side of the protective shell 1. The friction stone 11 can increase the friction. The end of the friction stone 11 near the placement box 6 has a locking groove 12, which can play a positioning role.
[0033] Reference Figures 2 to 4 The metal block 9 is engaged inside the engagement groove 12. The metal block 9 and the engagement groove 12 work together to achieve a positioning effect. The outside of the steel cable 5 is in contact with the inside of the engagement groove 12 and the outside of the steel cable 5 is in contact with the end of the metal block 9 near the friction stone 11. The metal block 9 and the engagement groove 12 can lock the steel cable 5. The inside of the protective shell 1 is rotatably connected to the rotating shaft 2. The rotating shaft 2 can rotate inside the protective shell 1. The outside of the rotating shaft 2 is equipped with a cable storage tray 3. When the rotating shaft 2 rotates, it can drive the cable storage tray 3 to rotate. The inside of the protective shell 1 is fixedly connected to the detector 13. The detector 13 is a Zhuoxin SQS8 non-contact stall monitor. The outside of the cable storage tray 3 is fixedly connected to the steel cable 5. By pulling the steel cable 5, the cable storage tray 3 can be pulled to rotate.
[0034] One end of the steel cable 5 is fixedly connected to a rotating assembly, which includes a rotating block 14. The rotating block 14 can limit the movement of the cable. The right end of the rotating block 14 is fixedly connected to one side of the steel cable 5. A locking lock 15 is rotatably connected to the outside of the rotating block 14. When the locking lock 15 rotates, the rotating block 14 will not rotate, thus preventing the steel cable 5 from getting tangled. A connecting lock 16 is engaged inside the locking lock 15. Kinetic energy can be transferred to the locking lock 15 through the connecting lock 16. A rotating column 17 is rotatably connected to the left side of the connecting lock 16. A hook 18 is fixedly connected to the left side of the rotating column 17. The rotating column 17 can rotate inside the hook 18. A spring plate 4 is fixedly connected to the outside of the rotating shaft 2. When the rotating shaft 2 rotates, it can drive the spring plate 4 to wind up. The spring plate 4 is made of high carbon steel, which can improve the service life of the spring plate 4. A rope 19 is fixedly connected to the right end of the protective shell 1. The rope 19 is made of aramid fiber rope and is used as a fixing point to prevent it from falling.
[0035] Working principle: When the user loses speed, the fall release structure inside the protective shell 1 can lock the user in place. Secondly, the detector 13 can detect the descent speed of the steel cable 5. At this point, the electronic valve 10 is opened to move the cable. Since the damper 7 and spring 8 are taut, they can push the metal block 9 to move. After the metal block 9 moves, it pushes the steel cable 5 into the locking groove 12, where it engages. This increases the friction between the metal block 9, the steel cable 5, and the locking groove 12, thereby reducing the descent speed of the steel cable 5. This protects the operator from the enormous impact force during the fall braking moment, reducing the risk of injury. Furthermore, the smoother deceleration process helps maintain stability and prevents damage to the rope or hook due to excessive impact, further ensuring the safety of high-altitude operations.
[0036] When it is necessary to prevent the steel cable 5 from knotting, after the hook 18 is fixed to the user's clothing, the user's rotation will cause the hook 18 to rotate. At the same time, the rotation of the hook 18 will cause the rotating column 17 to rotate inside the connecting lock 16. After the connecting lock 16 rotates, the steel cable 5 will not knot because the rotating block 14 can rotate inside the locking lock 15, thus protecting the steel cable 5 and preventing internal damage caused by knotting. When the steel cable 5 is pulled, the internal rotating shaft 2 will rotate, which will cause the spring plate 4 to contract, thereby generating potential energy. When the hook 18 is released, the potential energy generated by the spring plate 4 can pull the steel cable 5 back, thereby allowing the hook 18 to coil up, making the operator more flexible and reducing the risk of the steel cable 5 slack. When the user rotates, the steel cable 5 will not twist together, ensuring that the steel cable 5 is evenly stressed, avoiding internal damage caused by twisting, and ensuring the strength of the steel cable 5.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
