Description

Technical Field

[0001] This utility model relates to the technical field of safety protection equipment for high-altitude operations, specifically a high-altitude operation fall prevention safety lock. Background Technology

[0002] Working at heights is a common practice in industries such as construction, power, and communications, but it is inherently dangerous, especially since falls can cause serious personal injury. Therefore, the safety of workers is always a top priority, and fall protection equipment is a crucial facility for ensuring life safety.

[0003] Currently, although fall arrest devices on the market can provide protection to a certain extent, they still have many shortcomings. Traditional connection structures are prone to loosening or even accidental detachment when faced with complex high-altitude working environments and frequent use, which greatly threatens the lives of workers. For example, some simple hook or buckle connection methods will significantly reduce their connection stability after being subjected to large external forces or after long-term use, and cannot provide continuous and reliable safety protection for workers. Utility Model Content

[0004] The purpose of this utility model is to provide a safety lock for preventing falls during high-altitude operations, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a high-altitude operation fall protection safety lock, including a main rope body. There are two main rope bodies, each with a fixed hook and a fixed ring installed at its end. The ends of the two main rope bodies are also connected to reinforcing ropes. The other end of each reinforcing rope is equipped with a reinforcing mechanism. The reinforcing mechanism includes a reinforcing block and a reinforcing sleeve, both fixedly connected to the two reinforcing ropes. The outer wall of the reinforcing block is adapted to the inner wall of the reinforcing sleeve. The inner wall of the reinforcing sleeve has symmetrically formed cavities at both ends. A round shaft is fixedly connected to the inner wall of each cavity. Sleeves are rotatably connected to the outer arc walls of the two round shafts. Connecting plates are fixedly connected to opposite sides of the two sleeves. An elastic locking block is connected to the other end of each connecting plate. The outer arc walls of the reinforcing block have symmetrically formed locking grooves at both ends. A knob is installed at the end of the reinforcing block away from the reinforcing rope.

[0006] Furthermore, both the elastic block and the slot have a "V" shaped longitudinal section.

[0007] Furthermore, a first spring is connected between the two inner sidewalls of the elastic block.

[0008] Furthermore, the elastic locking block is made of spring steel.

[0009] Furthermore, the other end of the two main ropes is provided with a buffer mechanism, which includes a buffer member. The buffer member has a buffer cavity. The main rope is fixedly connected to a reinforcing steel ring. The reinforcing steel ring is fixedly connected to a sliding rod. One end of the sliding rod passes through the buffer cavity and is fixedly connected to an elliptical block at its end.

[0010] Furthermore, the elliptical block is made of rubber.

[0011] Furthermore, the slide bar is movably fitted with an arc-shaped connecting piece, and a second spring is fixedly connected to one inner wall of the buffer cavity near the reinforcing steel ring, with the other end of the second spring fixedly connected to the arc-shaped connecting piece.

[0012] Furthermore, a connector is fixedly installed on one of the outer side walls of the buffer member away from the reinforcing steel ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model achieves a stable connection between the main ropes through a reinforcement mechanism. The matching design of the reinforcement plug and the reinforcement sleeve, combined with the "V"-shaped elastic block and slot structure, allows the elastic block to be tightly locked into the slot under the action of the first spring after the reinforcement plug is inserted and rotated, achieving a fast and stable engagement. This enables the connection to withstand greater tension, making it less prone to loosening or accidental detachment in complex high-altitude working environments. This greatly improves the connection reliability of the safety lock and provides more reliable safety protection for workers.

[0015] 2. This utility model effectively solves the problem of insufficient buffering capacity of traditional equipment through the design of the buffer mechanism. When a fall occurs or a large tension occurs, the rubber elliptical block will undergo elastic deformation to initially absorb the impact energy. During the compression process, the elastic force of the second spring gradually increases, which can cancel out the impact force generated by the fall and significantly slow down the fall speed. Through the dual action of the deformation buffer of the elliptical block and the elastic buffer of the second spring, the impact force is greatly reduced to reduce the injury to the workers and improve the effectiveness of buffer protection.

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] See Figure 1 , Figure 2 and Figure 3 As shown, a high-altitude work fall protection safety lock includes two main ropes 1, each with a fixed hook 4 and a fixed ring 5 at its end. The ends of the two main ropes 1 are also connected to reinforcing ropes 22. The other end of each reinforcing rope 22 has a reinforcing mechanism, which includes a reinforcing block 6 and a reinforcing sleeve 7 fixedly connected to the two reinforcing ropes 22. The outer wall of the reinforcing block 6 is adapted to the inner wall of the reinforcing sleeve 7. The inner wall of the reinforcing sleeve 7 has symmetrically formed cavities 11 at both ends, and each cavity 11 has a fixedly connected inner wall. Two cylindrical shafts 9 are rotatably connected to sleeves 10 on their outer arc walls. Two sleeves 10 are fixedly connected to opposite sides of their opposite sides. Two connecting plates 12 are connected to the other ends of their opposite sides to an elastic block 13. Two grooves 8 are symmetrically opened at both ends of the outer arc wall of the reinforcing insert 6. A knob 15 is installed at the end of the reinforcing insert 6 away from the reinforcing rope 22. The longitudinal cross-sectional shape of the elastic block 13 and the groove 8 are both "V" shaped. A first spring 14 is connected between the two inner side walls of the elastic block 13. The elastic block 13 is made of spring steel.

[0025] In the specific implementation process, when it is necessary to reinforce the connection of the two main rope bodies 1, the operator aligns the reinforcing insert 6 with the opening of the reinforcing sleeve 7 and slowly inserts it. Then, the operator rotates the knob 15. The outer wall of the reinforcing insert 6 will squeeze the elastic block 13, causing the elastic block 13 to rotate around the circular axis 9 into the cavity 11. At the same time, the first spring 14 is compressed. When the reinforcing insert 6 rotates to the corresponding position of the elastic block 13 and the slot 8, the elastic restoring force of the first spring 14 pushes the elastic block 13 out and into the slot 8, thus achieving a stable connection between the reinforcing insert 6 and the reinforcing sleeve 7. When disassembly is required, the operator only needs to rotate the knob 15 to overcome the locking force between the elastic block 13 and the slot 8, causing the elastic block 13 to rotate around the circular axis 9 into the cavity 11 again until the elastic block 13 is completely disengaged from the slot 8. Then, the reinforcing insert 6 can be completely pulled out of the reinforcing sleeve 7.

[0026] It should be noted that the elastic block 13 is made of spring steel, which has good elasticity and toughness, ensuring that it is not easily deformed during repeated locking and unlocking, thus extending its service life. The "V"-shaped elastic block 13 and the slot 8 design can achieve rapid locking through the interaction of the inclined surfaces. At the same time, the locking state is stable when the knob 15 is rotated without external force, avoiding accidental disengagement and improving the reliability of the reinforcement.

[0027] See Figure 1 and Figure 4 As shown, the other end of the two main rope bodies 1 is provided with a buffer mechanism, which includes a buffer element 2. The buffer element 2 has a buffer cavity 16. The main rope body 1 is fixedly connected to a reinforcing steel ring 3. The reinforcing steel ring 3 is fixedly connected to a sliding rod 17. One end of the sliding rod 17 passes through the buffer cavity 16 and is fixedly connected to an elliptical block 21. The elliptical block 21 is made of rubber. The sliding rod 17 is movably fitted with an arc-shaped connecting piece 20. A second spring 19 is fixedly connected to an inner wall of the buffer cavity 16 near the reinforcing steel ring 3. The other end of the second spring 19 is fixedly connected to the arc-shaped connecting piece 20. A connecting piece 18 is fixedly installed on an outer wall of the buffer element 2 away from the reinforcing steel ring 3.

[0028] In practice, when a worker falls from height or experiences significant tension, the main rope 1 experiences a downward pull. This pull is transmitted to the slide bar 17 via the reinforcing steel ring 3, causing the slide bar 17 to slide inward along the buffer cavity 16. The elliptical block 21 slides against the inner wall of the buffer cavity 16 until it slides to the point where it abuts against the arc-shaped connecting piece 20. At this point, the rubber elliptical block 21 undergoes elastic deformation, absorbing some of the impact energy. Simultaneously, the slide bar 17 pushes the arc-shaped connecting piece 20 towards the reinforcing steel ring 3, compressing the second spring 19. During compression, the elastic force of the second spring 19 gradually increases, counteracting the impact force generated by the fall, thereby slowing down the fall speed and providing buffer protection for the worker. After the impact force disappears, the elastic restoring force of the second spring 19 pushes the arc-shaped connecting piece 20 and the slide bar 17 back to their original positions, preparing for the next possible fall.

[0029] Working principle:

[0030] Step 1: When it is necessary to reinforce the connection between the two main rope bodies 1, the operator inserts the reinforcing plug 6 into the opening of the reinforcing sleeve 7 and rotates the knob 15. During the process, the outer wall of the reinforcing plug 6 presses against the elastic block 13, causing it to rotate around the circular shaft 9 into the cavity 11. At the same time, the first spring 14 is compressed. When the reinforcing plug 6 rotates to the position where the elastic block 13 corresponds to the slot 8, the elastic restoring force of the first spring 14 pushes the elastic block 13 out and into the slot 8. The interaction of the inclined surfaces of the "V"-shaped structure achieves a stable connection. When the knob 15 is rotated without external force, the engagement state is stable, preventing accidental disengagement. When disassembling, the operator rotates the knob 15 to overcome the engagement force, causing the elastic block 13 to rotate back into the cavity 11 and disengage from the slot 8. The reinforcing plug 6 can then be pulled out of the reinforcing sleeve 7.

[0031] Step Two: When a worker falls from height or experiences significant tension, the tension of the main rope 1 is transmitted to the slide bar 17 through the reinforcing steel ring 3, causing the slide bar 17 to slide inward along the buffer cavity 16. The rubber elliptical block 21 moves with the slide bar 17 and undergoes elastic deformation when it comes into contact with the arc-shaped connecting piece 20, absorbing some of the impact energy. At the same time, the slide bar 17 pushes the arc-shaped connecting piece 20 to compress the second spring 19. The elastic force of the second spring 19 gradually increases with compression, offsetting the impact force of the fall and slowing down the fall speed. When the impact force disappears, the elastic restoring force of the second spring 19 pushes the arc-shaped connecting piece 20 and the slide bar 17 back to their original positions, preparing for the next possible fall.
