Description

A fall protection connection assembly for high-altitude operations on power transmission towers Technical Field

[0001] This utility model relates to the field of fall protection technology for high-altitude operations, specifically to a fall protection connection component for high-altitude operations on power transmission towers. Background Technology

[0002] The purpose of fall protection for high-altitude operations on power transmission towers is to ensure the safety of workers. Because power transmission towers are typically tens or even hundreds of meters high, with complex structures and harsh working environments, the consequences of a fall would be catastrophic. Therefore, effective fall protection measures are crucial. The importance of these measures is mainly reflected in two aspects: First, they prevent workers from being injured or killed by accidental falls, thus ensuring their safety; second, they help maintain the normal operation of the power transmission tower, avoiding serious consequences such as equipment damage and power outages caused by falls.

[0003] A search revealed that CN220080863U discloses a fall protection device for high-altitude operations. The device includes a support rail horizontally positioned on a building surface, a movable mounting base on the support rail, and a drive assembly on the mounting base for moving the mounting base. A lifting assembly is located at the bottom of the mounting base, comprising a rotating motor, a pulley, a steel wire rope, and a safety belt. The pulley is rotatably connected to the bottom wall of the mounting base, and the rotating motor is connected to the bottom wall of the mounting base and coaxially connected to the pulley. The steel wire rope is wound around the pulley, with one end extending beyond the pulley and detachably connected to the safety belt. This invention improves the efficiency of high-altitude operations for workers.

[0004] In the aforementioned high-altitude work fall protection device, the connection between the hanging ring and the carabiner is a single point. A single point connection can easily cause the worker to sway due to body swing or external impact. At the same time, this design relies solely on the connection between the hanging ring and the carabiner. If the hanging ring and the carabiner break, the high-altitude worker will fall directly, thus causing a safety accident. Summary of the Invention

[0005] This utility model proposes a fall protection connection component for high-altitude operations on power transmission towers, which solves the problems in the prior art where single-point connections easily cause workers to sway due to body swing or external impact; and when the lifting ring and carabiner break, it can cause high-altitude workers to fall directly, thus causing safety accidents.

[0006] A fall protection connection component for high-altitude operations on power towers includes an installation harness, wherein the installation harness has symmetrically arranged disassembly and assembly components on both sides inside the installation harness.

[0007] The main hoisting assembly is located on the outside of the mounting strap and can be quickly attached to and detached from the mounting strap at the assembly disassembly point;

[0008] A secondary lifting assembly is located in the middle inside the mounting strap and can provide emergency cushioning and fall prevention after being connected to the main lifting assembly.

[0009] Preferably, the main hoisting assembly includes:

[0010] Main chain;

[0011] An external rope is fixedly connected to the top of the outer side of the main connecting sleeve;

[0012] The bearing is installed inside the main coupling sleeve;

[0013] The outer ring of the bearing is fixedly connected to the main bushing.

[0014] Preferably, the main hoisting assembly further includes:

[0015] A branch rope that is fixedly connected to the inner ring of the bearing.

[0016] Preferably, the main hoisting assembly further includes:

[0017] A secondary connecting sleeve is fixedly connected to both ends of the branch rope;

[0018] A socket that is fixedly connected to the middle of the secondary sleeve.

[0019] Preferably, the disassembly / assembly assembly includes:

[0020] A two-way screw is rotatably connected to the inside of the mounting strap;

[0021] An inner groove is formed on the inner side of one end of the bidirectional screw.

[0022] Preferably, the disassembly / assembly assembly further includes:

[0023] A handle is provided where the bidirectional screw is located within the inner groove;

[0024] A spring coil is provided within the inner groove;

[0025] One end of the spring coil is fixedly connected to the inner wall of the inner groove;

[0026] The other end of the spring coil is fixedly connected to the handle.

[0027] Preferably, the disassembly / assembly assembly further includes:

[0028] A screw cap that is fixedly connected to the outside of the screw handle.

[0029] Preferably, the auxiliary lifting assembly includes:

[0030] An auxiliary rope is fixedly connected to the bottom outer side of the main connecting sleeve.

[0031] Preferably, the auxiliary lifting assembly further includes:

[0032] A damping spring is fixedly installed at the middle position inside the mounting strap.

[0033] Preferably, the auxiliary lifting assembly further includes:

[0034] A ring is fixedly connected to the extension end of the damping spring.

[0035] The beneficial effects of this utility model are as follows:

[0036] This invention features auxiliary connecting sleeves and sockets at both ends of the branch rope. After aligning the sockets with the docking slots, turning the bidirectional screw causes the two sets of sliding blocks to advance towards each other until the docking slot fits into the outside of the socket, completing the rapid assembly of the main lifting component at the location of the installation strap and disassembly component. This design uses two U-shaped branch ropes connected to the installation strap, which can effectively distribute the load at the fulcrum and maintain stability. At the same time, this design has an auxiliary lifting component in the middle of the installation strap that connects to the main lifting component. When the branch rope and the installation strap accidentally become detached, the auxiliary rope will be quickly straightened by the falling worker and replace the branch rope to maintain the connection with the installation strap. Meanwhile, the damping spring can buffer the moment the auxiliary rope is instantly straightened to prevent the auxiliary rope from breaking due to sudden force. The auxiliary rope provides double protection for workers at height. Attached Figure Description

[0044] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0045] Please refer to Figures 1, 2, 3, 4, and 5. This utility model provides a technical solution: a fall protection connection component for high-altitude operations on power transmission towers, including a mounting strap 1, with detachable components 3 symmetrically arranged on both sides inside the mounting strap 1.

[0046] The main hoisting component 2 is located on the outside of the mounting strap 1 and can be quickly attached to and detached from the mounting strap 1 at the disassembly component 3;

[0047] A secondary lifting assembly 4 is installed in the middle of the installation strap 1 and can provide emergency cushioning and fall prevention after being connected to the main lifting assembly 2;

[0048] This design solves the problems in existing technologies where single-point connections can easily cause workers to sway due to body swings or external impacts; and where breakage of the hoisting ring and carabiner can lead to workers falling directly from heights, causing safety accidents.

[0049] Please refer to Figure 4. The main hoisting assembly 2 includes:

[0050] Main chain 21;

[0051] An external rope 22 is fixedly connected to the top of the outer side of the main connecting sleeve 21;

[0052] Bearing 211 is installed inside the main sleeve 21;

[0053] The outer ring of bearing 211 is fixedly connected to the main coupling sleeve 21.

[0054] Main hoisting assembly 2 also includes:

[0055] Branch rope 23 is fixedly connected to the inner ring of bearing 211;

[0056] This design ensures that the branch rope 23 is rotatably connected to the main connecting sleeve 21 under the action of the bearing 211, and avoids wear caused by contact friction between the branch rope 23 and the main connecting sleeve 21.

[0057] Please refer to Figures 4 and 5. The main hoisting assembly 2 also includes:

[0058] A secondary connecting sleeve 24 is fixedly connected to the ends of both sides of the branch rope 23;

[0059] The socket 25 is fixedly connected to the middle of the secondary sleeve 24.

[0060] Assembly / disassembly component 3 includes:

[0061] A two-way screw 31 is rotatably connected to the inside of the mounting strap 1;

[0062] An inner groove 311 is formed on the inner side of one end of the bidirectional screw 31.

[0063] Assembly / disassembly component 3 also includes:

[0064] A handle 32 is provided in the inner groove 311 of the bidirectional screw 31;

[0065] A spring coil 322 is installed inside the inner groove 311;

[0066] One end of the spring coil 322 is fixedly connected to the inner wall of the inner groove 311;

[0067] The other end of the spring coil 322 is fixedly connected to the handle 32.

[0068] Assembly / disassembly component 3 also includes:

[0069] A screw cap 321 is fixedly connected to the outside of the screw handle 32;

[0070] When it is necessary to complete the assembly connection between the slide block 33 and the socket 25, you can hold the screw cap 321 and pull the screw handle 32 to the outside of the inner groove 311. Then, turn the screw handle 32 to rotate the inner groove 311. At this time, the slide block 33 with the threaded connection to the opposite thread on the outside of the double screw 31 moves synchronously towards each other until the mating groove 331 is fitted into the outside of the socket 25.

[0071] Similarly, the socket 25 can be removed from the mating groove 331;

[0072] Specifically, when the handle 32 is not being turned, the handle 32 will move to one side of the inner groove 311 under the elastic reset action of the inner groove 311 until the screw cap 321 is pressed against the outside of the inner groove 311. This design prevents workers at height from accidentally touching the handle 32. At the same time, the screw cap 321, which is pressed against the outside of the bidirectional screw 31, can also effectively prevent foreign objects from entering the inner groove 311.

[0073] Please refer to Figures 2 and 3. The auxiliary lifting assembly 4 includes:

[0074] An auxiliary rope 41 is fixedly connected to the bottom of the outer side of the main connecting sleeve 21.

[0075] Sub-lifting assembly 4 also includes:

[0076] A damping spring 42 is fixedly installed in the middle position inside the mounting strap 1.

[0077] Sub-lifting assembly 4 also includes:

[0078] The ring 43 is fixedly connected to the extension end of the damping spring 42;

[0079] The connection between the auxiliary rope 41 and the mounting strap 1 can be completed by tying the bottom of the auxiliary rope 41 to the loop 43.

[0080] Specifically, when the branch rope 23 becomes detached from the installation harness 1 due to an accident, the auxiliary rope 41 will be quickly straightened by the falling worker and replace the branch rope 23 to maintain the connection with the installation harness 1. At the same time, the damping spring 42 can act as a buffer when the auxiliary rope 41 is instantly straightened to prevent the auxiliary rope 41 from breaking due to sudden force. The auxiliary rope 41 can provide double protection for workers working at height.

[0081] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
