Description

Technical Field

[0001] This utility model relates to the field of fall protection devices, and in particular to a double-ended stable suspended iron tower fall protection device. Background Technology

[0002] Tower work is a crucial part of the maintenance of high-altitude power facilities. Workers need to climb dozens of meters of tower to inspect and repair equipment. The working environment is often challenging, with strong winds and direct sunlight. Safety protection measures directly affect the success or failure of the operation. Due to the high risk of the operation, tower fall arrest devices have become the core equipment to ensure personnel safety. The device consists of a vertical rail self-locking connector. It triggers braking by sensing the fall speed in real time, effectively controlling the personnel's slip distance and minimizing injuries from falls from heights.

[0003] A search revealed Chinese Patent Publication No. CN109550168A, which discloses a fall arrestor comprising a bracket, a rotating component, a safety belt, a brake disc, a brake block, and a return spring. The bracket has a first side plate with a stop block disposed on its outer side surface. The rotating component is rotatably mounted on the bracket. The safety belt is wound around the rotating component. The brake disc is coupled to the rotating component and has an inner side facing the outer side of the first side plate. The brake block is pivotally mounted on the brake disc and located between the inner side of the brake disc and the outer side of the first side plate. This design ensures that the brake block can abut against the stop block when in the deployed position, increasing the reliability of the fall arrestor during emergency locking. However, in practical use, the aforementioned device suffers from sudden fall arrest mechanism action, resulting in significant impact force on falling personnel and potential injury, and lacks a cushioning mechanism. Therefore, a double-ended stable suspended iron tower fall arrestor is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a double-ended stable suspended iron tower fall arrestor, which aims to improve the problems of sudden action of the fall arrest mechanism in the existing technology, large impact force on the falling personnel causing injury, and lack of cushioning device.

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.

[0041] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a double-ended stable suspended iron tower fall arrestor, comprising a shell 1, a steel wire rope 7, and a top pad 9. The shell 1 serves as an external protective structure, supporting and fixing internal components to prevent external impact and wear. The steel wire rope 7 connects the user to the anchor point, bearing the impact force during a fall and transmitting braking force. The bottom of the outer wall of the top pad 9 is provided with a multi-damping mechanism 2. The inner wall of the shell 1 is provided with a wear-resistant mechanism 3. The outer wall of the steel wire rope 7 is provided with a toothed mechanism 4, which includes a fixed disc 401 used to slow down the speed when subjected to impact. The outer wall of the fixed disc 401 is rotatably connected to the outer wall of the steel wire rope 7. A ratchet ring 402 is fixedly connected to the outer wall of the fixed disc 401. The ratchet ring 402 works in conjunction with the fixed disc 401 to facilitate self-locking of the device in an emergency. The bottom of the outer wall of the steel wire rope 7 is provided with a deceleration mechanism 5, which includes a differential disc 501. 501 utilizes its own inertia to offset part of the impact force brought by the descent. The outer wall of the differential disc 501 is fixedly connected to the outer wall of the wire rope 7. The front and rear sides of the outer wall of the differential disc 501 are provided with sliding grooves 502. The outer walls of the two sliding grooves 502 are slidably connected with sliders 503. The sliding grooves 502 and sliders 503 are used in conjunction. The outer walls of the two sliders 503 are fixedly connected with telescopic rods 504. The telescopic rods 504 utilize the preload of their own springs to play a certain buffering role. The bottom of the outer walls of the two telescopic rods 504 are fixedly connected with fixed seats 505. The fixed seats 505 are used for the stability of the slowing mechanism 5. The interior of the housing 1 is provided with a reinforcing mechanism 6. The reinforcing mechanism 6 includes a main shaft 602. The main shaft 602 is used to control the rotation of the ratchet. The outer wall of the main shaft 602 is fixedly connected to the interior of the housing 1. The outer wall of the main shaft 602 is fixedly connected with a ratchet cover 601 to protect the ratchet.

[0042] The multi-buffer mechanism 2 includes a pusher 201, the top of which is fixedly connected to the bottom of the top pad 9. The pusher 201 is the source of thrust for the piston 202. The piston 202 is fixedly connected to the bottom of the outer wall of the pusher 201, which is used to squeeze the bottom component. A first rubber pad 203 is fixedly connected to the bottom of the outer wall of the piston 202. Silicone grease 204 is fixedly connected to the bottom of the outer wall of the first rubber pad 203. A second rubber pad 205 is fixedly connected to the bottom of the outer wall of the silicone grease 204. The first rubber pad 203, the second rubber pad 205, and the silicone grease 204 are of different thicknesses, which can provide a three-level buffering effect against impact. A sleeve 206 is fixedly connected to the outer wall of the second rubber pad 205. The sleeve 206 is the location where the three-level buffering occurs. Multiple holes 207 are opened on the outer wall of the sleeve 206 to maintain the stability of the internal operation.

[0043] Specifically, the shell 1, as the external protective body, undertakes the basic functions of enclosing and supporting the internal components, while isolating the core structure from external impacts or friction. The steel wire rope 7, as the core transmission component connecting the high-altitude workers to the fixed anchor point, bears the instantaneous impact load and transmits the braking force to the locking device during a fall. The bottom outer wall of the top pad 9 integrates a multi-damping mechanism 2, which reduces the destructive effect of the fall by absorbing kinetic energy in stages. The inner wall of the shell 1 is covered with a wear-resistant mechanism 3. This structure reduces the wear on the shell 1 caused by the repeated movement of the steel wire rope 7 through material optimization, improving the overall durability of the equipment. The outer surface of the steel wire rope 7 is attached with a toothed mechanism 4, the main body of which is composed of a fixed disc 401. This disc is dynamically connected to the steel wire rope 7 through an outer wall rotating joint. The fixed disc 401 is rigidly fixed with a ratchet ring 402. When a sudden fall occurs, the ratchet ring 402 and the fixed disc 401 form a linkage meshing effect, realizing the automatic locking of the system in an emergency. Functionally, a deceleration mechanism 5 is configured near the bottom of the wire rope 7. The core component of this mechanism, the differential plate 501, generates a reverse torque based on its own rotational inertia, effectively reducing the accumulation of kinetic energy during the fall. The differential plate 501 is fixed to the surface of the wire rope 7 by a rigid connection. Symmetrically distributed grooves 502 are opened on its front and rear end faces. Each groove 502 is embedded with a slider 503 to form a sliding pair. The top of the two sets of sliders 503 are rigidly connected to the telescopic rod 504. The rod has a built-in pre-compression spring structure, which continuously releases impact energy through elastic deformation. The bottom end of the telescopic rod 504 is rigidly connected to the fixed base 505. The base provides a stable mechanical support platform for the deceleration mechanism 5. The core area of ​​the housing 1 is equipped with a reinforcement mechanism 6. Its main shaft 602 serves as the power transmission hub, undertaking the rotation control function of the ratchet system and forming an integral fixed structure with the housing 1 by a rigid connection. A ratchet cover 601 is configured on the outside of the main shaft 602, forming a three-dimensional protection system for the transmission components.

[0044] Reference Figure 1 , Figure 2 and Figure 6 The wear-resistant mechanism 3 includes a ceramic composite layer 301, which reduces friction and wear through its high hardness characteristics, extending the service life of the shell 1. The outer wall of the ceramic composite layer 301 is fixedly connected to the inner wall of the shell 1. The inner wall of the ceramic composite layer 301 is fixedly connected to a shape memory alloy 302, which assists in structural reset through its shape recovery characteristics after impact, enhancing the cushioning performance. The inner wall of the shape memory alloy 302 is fixedly connected to an aerogel 303. The inner wall of the aerogel 303 is fixedly connected to a carbon fiber composite layer 304, which provides high-strength and lightweight support, improving the tensile and compressive strength of the shell 1. The inner wall of the carbon fiber composite layer 304 is fixedly connected to a tetrafluoroethylene coating 305, which uses a low coefficient of friction to ensure smooth sliding of the wire rope 7 and reduce the risk of jamming. The inner wall of the shell 1 is fixedly connected to a reinforcing pin 306, which strengthens the key connection parts of the shell 1 and prevents breakage caused by stress concentration.

[0045] Specifically, the wear-resistant mechanism 3 is composed of multiple functional materials. The ceramic composite layer 301 serves as the outermost protective layer. Its ultra-high surface hardness significantly reduces frictional wear between the inner wall of the shell 1 and the steel wire rope 7, extending the overall service life of the equipment. This layer forms a rigid bond with the inner wall of the shell 1 through a high-temperature sintering process. The inner side of the ceramic composite layer 301 is tightly fixed with a shape memory alloy 302. This material can recover its original shape based on the shape memory effect after being subjected to impact loads, providing the system with dynamic buffering and structural self-repair capabilities. The shape memory alloy 302 is connected to the aerogel 303 on the inner side. Its ultra-low thermal conductivity effectively blocks the heat generated during the fall from reaching the shell. The body 1 conducts the load and avoids the degradation of material properties caused by high temperature. The aerogel 303 integrates a carbon fiber composite layer 304 on the inside, which forms a high-strength and lightweight support structure through directional weaving process. This simultaneously improves the axial tensile strength and radial compressive stability of the shell 1. The surface of the carbon fiber composite layer 304 is covered with a tetrafluoroethylene coating 305. Its extremely low coefficient of friction ensures that the resistance of the steel wire rope 7 is minimized when sliding in the inner cavity of the shell 1, preventing motion jamming. Reinforcing pins 306 are embedded in the key stress concentration areas of the inner wall of the shell 1. These pins are made of high-strength alloy material and penetrate through the multi-layer structure. By dispersing local loads, they prevent the shell 1 from brittle fracture under extreme working conditions.

[0046] Reference Figure 1 , Figure 2 and Figure 5 The bottom of the outer wall of the wire rope 7 is fixedly connected to the lower hook lock 8, which is directly connected to the user's safety belt. When triggered, the wire rope 7 is automatically locked to prevent falling. The outer wall of the fixed plate 401 is fixedly connected to the outer wall of the main shaft 602. The top of the outer wall of the housing 1 is fixedly connected to the hook rope 11. The top of the outer wall of the hook rope 11 is fixedly connected to the upper hook lock 10, which is fixed to the high-altitude anchor point as a static support point of the fall protection system to ensure stable force. The bottom of the outer wall of the fixed seat 505 is fixedly connected to the top of the outer wall of the sleeve 206. The outer wall of the main shaft 602 is rotatably connected to the inner wall of the housing 1.

[0047] Specifically, the end of the wire rope 7 is rigidly connected to the hook lock 8. This component serves as the direct connection terminal of the safety belt and achieves instant locking of the wire rope 7 at the moment of fall through a mechanical linkage mechanism. The fixed plate 401 forms a power transmission structure with the main shaft 602 through a rigid connection with the outer wall. The hook rope 11 is set on the outer edge of the top of the housing 1 as the load-bearing medium of the high-altitude anchor point. The top of the hook lock 10 is rigidly fixed. This lock serves as the static load-bearing foundation of the fall protection system and maintains the overall force balance of the system. The bottom of the fixed seat 505 and the top of the sleeve 206 form a mechanical transmission channel through a rigid connection. The main shaft 602 serves as the power transmission hub and achieves controllable rotational movement in the inner cavity of the housing 1 through a precision bearing assembly.

[0048] Working principle: First, the shell 1 serves as an external protective structure, supporting and fixing the internal components to resist external impacts and wear. The steel wire rope 7 connects the user to the anchor point, bearing the impact force of the fall and transmitting braking force. In the multi-buffering mechanism 2 at the bottom of the outer wall of the top pad 9, the push column 201 pushes the piston 202, driving the three-stage buffer structure composed of the first rubber pad 203, silicone grease 204, and second rubber pad 205. The three-stage buffer is achieved in the sleeve 206 through materials of different thicknesses. In the toothed mechanism 4 on the outer wall of the steel wire rope 7, the ratchet ring 402 connected to the fixed plate 401 can achieve self-locking of the device in an emergency. In the deceleration mechanism 5 at its bottom, the differential plate 501 uses inertia to offset the impact force. The slide groove 502 cooperates with the slider 503. The telescopic rod 504 uses the spring preload to buffer. The fixed seat 505 ensures stability. The reinforcement mechanism 6 inside the shell 1 controls the rotation of the wheel through the main shaft 602. The ratchet cover 601 plays a protective role. The entire mechanism provides a complete buffer mechanism to avoid the impact force from causing injury to the human body.

[0049] Furthermore, the wear-resistant mechanism 3 consists of the following components from the outside to the inside: a ceramic composite layer 301 sintered at high temperature on the inner wall of the shell 1, which reduces frictional loss of the steel wire rope 7 due to its ultra-high hardness; a shape memory alloy 302 that provides self-healing cushioning after impact; an aerogel 303 that uses its ultra-low thermal conductivity to block heat; a carbon fiber composite layer 304 that is directionally woven to strengthen axial strength; and a tetrafluoroethylene coating 305 that uses low friction to ensure the smoothness of the rope. Alloy reinforcing pins 306 are embedded in key stress areas to distribute the load and prevent the shell 1 from cracking. The multi-layer composite structure simultaneously achieves wear resistance, cushioning, heat insulation, high strength, and smooth movement, significantly improving the durability of the equipment.
