[0002] Fall arresters for power transmission towers are devices used to ensure the safety of workers at heights. They provide necessary protection in the event of a fall, preventing or mitigating fall injuries.
[0003] While existing fall arrest devices for power transmission towers can prevent workers from falling, traditional fall arrest devices are not very effective and tend to slip during use. They are also inconvenient to install, requiring a significant amount of time for installation. Therefore, a new fall arrest device for power transmission towers has been developed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a fall arrest device for power transmission towers, which has the advantages of good stability and easy installation, thus solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a fall arrestor for power transmission towers, comprising a mounting frame, a sliding groove on the outer wall of the mounting frame, a fixing component on the inner wall of the mounting frame, a limiting groove on the outer wall of the mounting frame, a baffle slidably connected to the inner wall of the limiting groove, a limiting block placed on the outer wall of the baffle, a placement groove on the inner wall of the limiting block, one end of a spring fixedly mounted on the inner wall of the placement groove, a locking block fixedly mounted on the other end of the spring, and a locking groove on the outer wall of the limiting block.
[0006] As a preferred technical solution of this utility model: the outer wall of the mounting frame is fixedly equipped with a hook lock, and the outer wall of the fixing component is provided with an anti-slip clamping block.
[0007] As a preferred technical solution of this utility model: the fixing component includes a pressing block, a fixing block and a limiting rod are fixedly assembled on the outer wall of the pressing block, a rotating rod is rotatably connected to the inner wall of the fixing block, one end of a rotating plate is fixedly assembled on the outer wall of the rotating rod, a rotating column is rotatably connected to the other end of the rotating plate, a rotating block is fixedly assembled on the outer wall of the rotating column, a moving block is fixedly assembled on the outer wall of the rotating block, a snap-fit block is fixedly assembled on the outer wall of the moving block, a second spring is fixedly assembled on the end of the rotating block near the limiting rod, a limiting shell is provided on the outer wall of the limiting rod, and a third spring is provided on the outer wall of the limiting shell.
[0008] As a preferred technical solution of this utility model: the pressing block is slidably connected to the inner wall of the mounting frame, the limiting shell and spring three are fixedly assembled to the inner wall of the mounting frame, the spring two is fixedly assembled to the outer wall of the mounting frame, the limiting rod is slidably connected to the inner wall of the limiting shell, and the limiting rod is fixedly assembled to the anti-slip clamping block.
[0009] As a preferred technical solution of this utility model: the locking block is adapted to the inner wall of the locking groove, the moving block is slidably connected to the inner wall of the sliding groove, and the locking block is locked to the inner wall of the sliding groove.
[0010] As a preferred technical solution of this utility model: there are two of each of the baffle, limiting block, spring one and locking block, and the two baffles, limiting blocks, spring one and locking blocks are respectively located on the outer wall of the mounting frame.
[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The fall arrestor for this power transmission tower is installed by placing the mounting bracket on the outer wall of the tower. Workers then push the baffles along the inner wall of the limiting groove, causing the two baffles to collide. At this point, a limiting block is placed on the outer wall of the locking groove, and the worker pulls the locking block, causing a spring to extend and retract. Once the locking block reaches the opening of the locking groove, the pulling is stopped, releasing the spring's potential energy. This spring then moves the locking block towards the inner wall of the locking groove. When the locking block is placed on the inner wall, it secures the two baffles, thus facilitating the installation of the mounting bracket.
[0012] 2. The fall arrestor for this power transmission tower works as follows: When fixing the mounting frame, the operator pulls the rotating plate, causing the rotating column and rotating block to rotate on the inner wall of the rotating plate. As the rotating block rotates, it causes the moving block to move on the inner wall of the sliding groove. This movement causes the locking block to disengage from the inner wall of the sliding groove, releasing the limiting position of the rotating plate. Simultaneously, the elastic potential energy of spring two is released during the rotation, causing it to move the pressing block and limiting rod on the inner wall of the mounting frame. At the same time, the elastic potential energy of spring three is released, causing the limiting rod and anti-slip clamping block to move on the inner wall of the mounting frame, thus clamping the tower and achieving good stability.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1 - Figure 7 A fall arrestor for power transmission towers includes a mounting frame 1. The outer wall of the mounting frame 1 has a sliding groove 5, and the inner wall of the mounting frame 1 has a fixing component 3. The outer wall of the mounting frame 1 has a limiting groove 7, and the inner wall of the limiting groove 7 is slidably connected to a baffle 4. A limiting block 6 is placed on the outer wall of the baffle 4. The inner wall of the limiting block 6 has a placement groove 9, and one end of a spring 10 is fixedly mounted on the inner wall of the placement groove 9. The other end of the spring 10 is fixedly mounted with a locking block 11, and the outer wall of the limiting block 6 has a locking groove 12.
[0017] In the above structure, during the installation of the mounting bracket 1, the worker first places the mounting bracket 1 on the outer wall of the iron tower. Then, the worker pushes the baffle 4 to move on the inner wall of the limiting groove 7 until the two sets of baffles 4 collide. Next, the worker places the limiting block 6 on the outer wall of the locking groove 12 and pulls the locking block 11, causing the locking block 11 to drive the spring 10 to extend and retract. When the locking block 11 moves to the opening of the locking groove 12 and stops pulling, the elastic potential energy of the spring 10 is released. The spring 10 then drives the locking block 11 to move towards the inner wall of the locking groove 12 until the locking block 11 is stably placed on the inner wall of the locking groove 12. Finally, the two baffles 4 are fixed, thus simplifying the installation process of the mounting bracket 1.
[0018] In a preferred embodiment: the outer wall of the mounting bracket 1 is fixedly fitted with a hook lock 2, and the outer wall of the fixing component 3 is provided with an anti-slip clamping block 8.
[0019] In the above structure, the hook lock 2 is used to limit and fix the rope, and the anti-slip clamping block 8 is used to clamp the iron tower, making the equipment more stable when placed.
[0020] In a preferred embodiment: the fixing component 3 includes a pressing block 301, a fixing block 302 and a limiting rod 304 are fixedly mounted on the outer wall of the pressing block 301, a rotating rod 303 is rotatably connected to the inner wall of the fixing block 302, one end of a rotating plate 308 is fixedly mounted on the outer wall of the rotating rod 303, a rotating column 309 is rotatably connected to the other end of the rotating plate 308, a rotating block 310 is fixedly mounted on the outer wall of the rotating column 309, a moving block 311 is fixedly mounted on the outer wall of the rotating block 310, a snap-fit block 312 is fixedly mounted on the outer wall of the moving block 311, a second spring 305 is fixedly mounted on the end of the rotating block 310 near the limiting rod 304, a limiting shell 306 is provided on the outer wall of the limiting rod 304, and a third spring 307 is provided on the outer wall of the limiting shell 306.
[0021] In the above structure, during the fixed operation of the mounting frame 1, the operator pulls the rotating plate 308, causing the rotating column 309 and the rotating block 310 to rotate along the inner wall of the rotating plate 308. As the rotating block 310 rotates, the moving block 311 moves on the inner wall of the sliding groove 5, thereby causing the locking block 312 to disengage from the inner wall of the sliding groove 5, thus releasing the limiting position of the rotating plate 308. As the rotating plate 308 rotates, the elastic potential energy of the second spring 305 is released, pushing the pressing block 301 and the limiting rod 304 to move on the inner wall of the mounting frame 1. At the same time, the elastic potential energy of the third spring 307 is also released, working together with the second spring 305 to cause the limiting rod 304 and the anti-slip clamping block 8 to move on the inner wall of the mounting frame 1, ultimately achieving a stable clamping of the tower and ensuring excellent fixing effect.
[0022] In a preferred embodiment: the pressing block 301 is slidably connected to the inner wall of the mounting frame 1, the limiting shell 306 and the third spring 307 are fixedly assembled to the inner wall of the mounting frame 1, the second spring 305 is fixedly assembled to the outer wall of the mounting frame 1, the limiting rod 304 is slidably connected to the inner wall of the limiting shell 306, and the limiting rod 304 is fixedly assembled to the anti-slip clamping block 8.
[0023] In the above structure, the mounting bracket 1 is used to limit the fixed component 3 so that the fixed component 3 will not fall when placed. The limiting shell 306 is used to support the limiting rod 304 so that the limiting rod 304 will not tilt when moving. When the limiting rod 304 moves, it will drive the anti-slip clamping block 8 to move.
[0024] In a preferred embodiment: the locking block 11 is adapted to the inner wall of the locking groove 12, the moving block 311 is slidably connected to the inner wall of the sliding groove 5, and the locking block 312 is locked to the inner wall of the sliding groove 5.
[0025] In the above structure, the baffle 4 is fixed when the locking block 11 is placed on the inner wall of the locking groove 12. The moving block 311 is limited by the sliding groove 5, so that the moving block 311 can only move on the inner wall of the sliding groove 5. The rotating plate 308 is limited and fixed by the locking block 312 through the locking of the sliding groove 5, so that the rotating plate 308 will not rotate when placed.
[0026] In a preferred embodiment, there are two of each of the baffle 4, limiting block 6, spring 10 and locking block 11, and the two baffles 4, limiting block 6, spring 10 and locking block 11 are located on the outer wall of the mounting frame 1.
[0027] In the above structure, the slot of the mounting bracket 1 is closed by two baffles 4, and the two baffles 4 are fixed by two limit blocks 6, spring 10 and locking block 11, so that the baffles 4 are more stable when placed and will not move.
[0028] Working principle: During installation, the worker first places the mounting bracket 1 on the outer wall of the tower, then pushes the baffle 4 to move on the inner wall of the limiting groove 7, causing the two sets of baffles 4 to collide. Next, the worker places the limiting block 6 on the outer wall of the locking groove 12 and pulls the locking block 11, causing the spring 10 to extend and retract. When the locking block 11 moves to the opening of the locking groove 12 and stops pulling, the elastic potential energy of the spring 10 is released, thereby pushing the locking block 11 to move towards the inner wall of the locking groove 12. After fixing the locking block 11 to the inner wall of the locking groove 12, the installation of the mounting bracket 1 is completed. During the process of fixing the mounting bracket 1, the worker pulls and rotates... Plate 308 causes the rotating column 309 and rotating block 310 to rotate on the inner wall of plate 308. During rotation, the rotating block 310 pushes the moving block 311 to move on the inner wall of the sliding groove 5, causing the locking block 312 to disengage from the inner wall of the sliding groove 5, thereby releasing the limiting position of plate 308. As plate 308 rotates, the elastic potential energy of spring 2 305 is released, causing the pressing block 301 and limiting rod 304 to move on the inner wall of mounting frame 1. At the same time, the elastic potential energy of spring 307 is also released, assisting the limiting rod 304 and anti-slip clamping block 8 to move on the inner wall of mounting frame 1, achieving a firm clamping of the tower and ensuring stability.
