Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a safety belt hook anti-fall device for working at heights. Background Technology

[0002] Architecture is a general term for buildings and structures. It refers to the artificial environment created by people to meet the needs of social life by using the material and technical means they have mastered and applying certain scientific laws and aesthetic principles.

[0003] In the construction industry, for example, in high-altitude operations such as scaffolding erection, steel structure assembly, and truss painting, traditional high-altitude operations use traction steel wire ropes as lifelines. Safety belt hooks are suspended on the steel wire ropes. The safety belt hooks slide in contact with the steel wire ropes for a long time, which can easily wear out the safety belt hooks or cause the safety belts to be cut, punctured, or torn, thus reducing safety. Utility Model Content

[0004] The purpose of this utility model is to overcome the problems mentioned in the background art and provide a safety belt hook anti-fall device for working at heights. This device provides an effective anti-fall measure for working at heights, strengthens the weakest contact part of the safety protection measures, thereby indirectly avoiding damage to the safety belt when it slides and improving the safety of operators working at heights.

[0005] The objective of this utility model is mainly achieved through the following technical solutions:

[0006] A safety belt hook fall arrestor for high-altitude operations includes a mounting frame with both ends bent downwards. Two hooks are mounted on the top of the mounting frame, each hook's end fixed to the top of the frame. A connecting shaft is positioned between the hooks, with its ends fixed to the hook ends. A guide shaft is housed within the cavity of the mounting frame, with both ends fixed to the frame. Two connecting pieces are fitted onto the guide shaft, each movable along the shaft. A hook is positioned between the connecting pieces, connecting to the connecting pieces. In construction applications such as scaffolding erection, steel structure assembly, and truss painting, traditional high-altitude operations often use traction steel wire ropes as lifelines. Safety belt hooks are suspended from these ropes, and prolonged contact and sliding between the hooks and rope can lead to wear, cuts, punctures, or tears in the safety belt, reducing safety. To address the aforementioned issues, this solution designs a safety belt hook fall arrestor for high-altitude operations. It employs a mounting frame with both ends bent downwards. Two hooks are installed at the top of the frame, each hook's end fixed to the top. These hooks connect to a closed-end steel wire rope or pipe. Made of metal, the hooks are wear-resistant and non-deformable, allowing them to move along the wire rope or pipe, extending their service life and improving safety. A connecting shaft is positioned between the hooks, with each end fixed to one of the hooks. Locking caps are fixed to both ends of the connecting shaft, connecting the two hooks together and increasing stability. A guide shaft is installed within the cavity of the mounting frame, with both ends fixed to the frame. Two connecting plates are fitted onto the guide shaft, allowing them to move along the shaft. A hook connects between the connecting plates. The safety belt connects to the hook, enabling it to move along the wire rope with the device. This reduces friction on the safety belt, maintaining its integrity and extending its service life.

[0007] Furthermore, a first limiting buckle is fitted on the connecting shaft, and the first limiting buckle can move along the connecting shaft; a second limiting buckle is fitted on the guide shaft, and the second limiting buckle can move along the guide shaft. A safety rope is provided between the first and second limiting buckles, and the safety rope is connected to both the first and second limiting buckles. Connecting the hook and the guide shaft together with the safety rope can prevent the guide shaft from falling if it suddenly detaches from the mounting bracket, thereby improving safety. The first limiting buckle can move along the connecting shaft, and the second limiting buckle can move along the guide shaft, facilitating appropriate position adjustments. The second limiting buckle is positioned between the connecting pieces.

[0008] Furthermore, a triangular hook is fitted onto the guide shaft, and the triangular hook can move along the guide shaft. A connecting piece is disposed between the triangular hooks. The triangular hook is an existing component, with through holes on its protruding triangles. The guide shaft passes through one of the through holes, and the other two through holes facilitate the hanging of other equipment.

[0009] Furthermore, locking pins are provided between the connecting pieces. After passing through the hook, the two ends of the locking pins are fixed to the connecting pieces respectively. The locking pins are located below the guide shaft. The hook is fixed to the connecting pieces by the locking pins.

[0010] Furthermore, a baffle is installed on the hook. The baffle is connected to the hook and can rotate around the connection point to close or open the open end of the hook. The baffle closes the open end of the hook, so when the safety belt is hooked on the hook, the baffle rotates to close the opening, preventing the safety belt from slipping off the hook. The baffle closes the opening using a spring. The elasticity of the spring keeps the baffle pressed against the opening. To open it, force needs to be applied to compress the spring and open the opening, thus preventing the safety belt from slipping off.

[0011] In summary, compared with the prior art, this utility model has the following beneficial effects: This utility model provides an effective fall prevention measure for working at heights, strengthens the weakest contact part of the safety protection measures, thereby indirectly avoiding damage to the safety belt when it slides, and improving the safety of operators working at heights.

[0019] like Figure 1 As shown in this embodiment, a safety belt hook fall arrestor is suitable for high-altitude operations on construction sites. It can move with the worker's position within a closed steel pipe at both ends. The safety belt hook fall arrestor can slide freely without compromising the safety belt's safety during sliding. It includes a mounting frame 4 with both ends bent downwards. The mounting frame 4 is a metal plate with both ends bent downwards at 90 degrees. Two hooks 2 are installed at the top of the mounting frame 4, each with one end vertically fixed to the top of the mounting frame 4. The hooks 2 are used to hang on a closed wire rope or steel pipe. The hooks 2 are made of metal, are wear-resistant and will not deform, and can move along the wire rope or steel pipe, extending their service life and improving safety. A connecting shaft 1 is provided between the hooks 2, with locking caps 3 fixed at both ends. The ends of the connecting shaft 1 are fixed to the locking caps 3, thus connecting the two hooks 2 together and increasing their stability.

[0020] A guide shaft 9 is installed in the cavity of the mounting frame 4. Both ends of the guide shaft 9 are fixed to the mounting frame 4. Two connecting pieces 10 are fitted onto the guide shaft 9, and both connecting pieces 10 can move along the guide shaft 9. A hook 12 is installed between the connecting pieces 10, and the hook 12 is connected to the connecting piece 10. The safety belt is connected to the hook 12, allowing the safety belt to move along the wire rope with the device. This reduces friction on the safety belt itself, maintaining its integrity and extending its service life.

[0021] A first limiting buckle 5 is fitted onto the connecting shaft 1, and the first limiting buckle 5 can move along the connecting shaft 1; a second limiting buckle 8 is fitted onto the guide shaft 9, and the second limiting buckle 8 can move along the guide shaft 9. A safety rope 6 is provided between the first limiting buckle 5 and the second limiting buckle 8, and the safety rope 6 is connected to both the first limiting buckle 5 and the second limiting buckle 8. The safety rope 6 connects the hook 2 and the guide shaft 9 together, which can prevent the guide shaft 9 from falling when it suddenly falls off the mounting bracket 4, thereby improving safety. The first limiting buckle 5 can move along the connecting shaft 1, and the second limiting buckle 8 can move along the guide shaft 9, which facilitates appropriate position adjustment. The second limiting buckle 8 is positioned between the connecting pieces 10.

[0022] A triangular hook 7 is fitted onto the guide shaft 9, and the triangular hook 7 can move along the guide shaft 9. A connecting piece 10 is disposed between the triangular hooks 7. The protruding triangles of the triangular hook 7 are provided with through holes. The guide shaft passes through one of the through holes, and the other two through holes are convenient for suspending other equipment to prevent the device from falling off or for secondary wire rope safety.

[0023] A locking pin 11 is provided between the connecting pieces 10. After passing through the hook 12, the locking pin 11 is fixed at both ends to the connecting piece 10. The locking pin 11 is located below the guide shaft 9. The hook 12 is fixed to the connecting piece 10 by the locking pin 11 to ensure its stability.

[0024] A baffle 13 is provided on the hook 12. The baffle 13 is connected to the hook 12 and can rotate around the connection point to close or open the opening end of the hook 12. After the safety belt is hung on the hook 12, the baffle 13 rotates to close the opening, which can prevent the safety belt from slipping off the hook 12. The baffle 13 closes the opening by a spring. The elasticity of the spring is used to push the baffle 13 against the opening to close it. When opening, force needs to be applied to compress the spring to open the opening, so that the safety belt will not slip off.

[0025] This device slides in contact with the wire rope or steel pipe, while the lower part of the hook is fastened to the safety rope, thus solving the problem of the traditional safety rope being directly attached to the wire rope or other components and avoiding wear and tear on the safety belt.
