Description

Technical Field

[0001] This utility model relates to the technical field of live-line working equipment, specifically a backup protective rope fixing device for live-line working. Background Technology

[0002] In live-line work (such as insulated pole work, insulated platform work, etc.), backup safety ropes are an important safety measure to prevent falls from heights, and belong to the second line of defense in the "double protection" principle (work positioning + fall protection).

[0003] For workers on insulated platforms, the backup safety rope is usually tied to the worker's body (usually around the waist) at one end and connected to the insulated platform at the other end. Although this can provide some safety protection for the workers, the rope is loose because the end of the rope is connected to the insulated platform and the workers need to walk on the platform. It cannot prevent the workers from slipping off the platform and only serves to prevent them from falling to the ground. In short, the protection is insufficient. Therefore, in view of the above-mentioned problems, this technical solution proposes a backup protective rope fixing device for live-line work. Utility Model Content

[0004] The purpose of this utility model is to provide a backup safety rope fixing device for live-line work, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A backup safety rope fixing device for live-line work includes a backup safety rope fixing mechanism, which includes a ratchet tensioner. A strap is connected to one side of the ratchet tensioner, and a set of arc-shaped fixing rings is rotatably connected to the other side of the ratchet tensioner. The strap is tied to the utility pole on one side of the insulating platform, while the arc-shaped fixing rings are tightly attached to the utility pole on the opposite side of the strap. The strap is then tightened by controlling the ratchet tensioner, which allows for quick and stable control of the binding installation between the strap, the arc-shaped fixing rings, and the utility pole. A set of hooks is welded to one side of the middle of the arc-shaped fixing ring. The hooks are attached to the end of the backup safety rope, and the opposite end is tied to the worker. This allows the backup safety rope on the worker working on the insulated platform to be directly connected to the utility pole for limitation. This prevents the worker from falling off the insulated platform while working around the utility pole, thus greatly improving the safety protection of the worker.

[0006] Compared with the prior art, the beneficial effects of this utility model are: by directly fixing the backup safety rope to the utility pole, the problem of the safety rope being loose is eliminated, and the workers are effectively prevented from slipping off the insulated platform, rather than just being prevented from falling to the ground.

[0007] The ratchet tensioner works in conjunction with the straps and arc-shaped fixing rings to achieve a tight binding installation with the utility pole, preventing the device from shifting or loosening during operation.

[0008] The ratchet tensioner features a one-way locking design, and the operating handle can quickly tighten the strap, reducing installation time. The release lever is easy to disassemble, making it suitable for live-line work scenarios with frequent movement.

[0009] This device can be used in conjunction with existing insulated platforms and guardrails; the backup protective rope is made of high-strength antistatic fiber (such as aramid) or insulated rope, which is suitable for live environments.

[0010] This device has a simple structure and is mainly composed of standard parts (such as ratchet tensioners and straps), making it easy to manufacture and maintain, thus reducing the investment cost of safety equipment. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Please see Figures 1-3 A backup safety rope fixing device for live-line work includes a backup safety rope fixing mechanism 5. The backup safety rope fixing mechanism 5 includes a ratchet tensioner 6. A strap 7 is connected to one side of the ratchet tensioner 6, and a set of arc-shaped fixing rings 8 are rotatably connected to the other side of the ratchet tensioner 6. The strap 7 is tied to the utility pole 1 on one side of the insulating platform 3, while the arc-shaped fixing rings 8 are tightly attached to the utility pole 1 on the opposite side of the strap 7. Then, by controlling the ratchet tensioner 6 to tighten the strap 7, the binding installation between the strap 7, the arc-shaped fixing rings 8 and the utility pole 1 can be quickly and stably controlled. A set of connecting rings 14 is welded to one side of the middle of the arc-shaped fixing ring 8 via a connecting block 15. An elastic hook 13 is hooked to the end of the backup safety rope 12. The end of the backup safety rope 12 relative to the elastic hook 13 is tied to the worker. This allows the worker on the insulating platform 3 to have their backup safety rope directly connected to the utility pole 1 for limitation, preventing them from falling off the insulating platform 3 while they are working around the utility pole 1, thus greatly improving the safety protection of the worker.

[0020] In this embodiment of the invention, a hook ring 10 is connected to one end of the strap 7 away from the ratchet tensioner 6. A hook post 11 is installed inside the arc-shaped fixing ring 8 corresponding to the hook ring 10. The hook ring 10 is hooked onto the hook post 11 to realize the opening and closing between the strap 7 and the arc-shaped fixing ring 8, thereby binding it to the utility pole 1. Multiple guard rods 4 are fixedly installed on one side of the top of the insulating platform 3. The guard rods 4 are used to provide hand support for the workers, that is, to provide safety barriers. At the same time, a reinforcing rod is installed at the bottom of the insulating platform 3 to maintain the insulating platform 3, the reinforcing rod and the utility pole 1 in a triangular distribution, thereby controlling the insulating platform 3 to be sufficiently stable. Specifically, the reinforcing rod, the insulating platform 3, and the utility pole 1 are all detachably fixedly connected by the platform fixing frame 2. The platform fixing frame 2 usually adopts a structure of clamping rings and bolts. This is just one example of a structure. Details can be achieved by using conventional structures. It will not be elaborated on here, nor will it be limited.

[0021] In one embodiment of the present invention, the backup protective rope 12 is made of high-strength antistatic fiber (such as aramid, Dyneema) or insulating rope (suitable for direct contact with charged bodies), etc. Among them, the elastic hook 13 adopts a spring-locking safety hook (automatic locking type), and its structural features are as follows: The hook body is made of aluminum alloy or high-strength engineering plastic and contains an internal spring mechanism. It is designed with a double-locking system: a main lock (spring automatically closes the hook gate to prevent accidental opening); and a secondary lock (manually rotates the locking sleeve or latch to further lock the hook gate) (compliant with EN 362 standard). The hook opening is typically oval or D-shaped for easy and quick connection to the ring anchor point. The attached diagram is only a simplified illustration of its structure; for details, please refer to existing related technologies.

[0022] In a preferred embodiment of the present invention, the ratchet tensioner 6 includes a main frame, a ratchet, a pawl, a handle, a strap fixing mechanism, and a release lever; The main frame is made of metal (such as steel or aluminum alloy) or high-strength plastic, bearing the stress of the entire mechanism and including the installation space for strap channels, ratchet, and gears. The ratchet is a circular gear with serrated teeth that can only rotate in one direction (to prevent backflow) and works with the pawl to achieve a "one-way locking" function. The pawl is designed as a small spring-controlled latch that engages with the ratchet teeth to prevent it from reversing; when the ratchet rotates forward (tightening), the pawl slides through the teeth; when it rotates backward, it locks in place to prevent loosening. The handle is for manual operation and amplifies the pulling force through the lever principle, so that the straps are gradually tightened. It usually adopts a folding design to save space.

[0023] The strap fixing mechanism includes a strap inlet, a strap 7 insertion point, and a strap outlet where the strap 7 is tightened and fixed. Release lever: When the release lever is pressed or moved, the pawl disengages from the ratchet, allowing the strap 7 to detach freely.

[0024] The accompanying drawing is only a simplified illustration of the ratchet tensioner 6. For details, please refer to the existing related technical content for understanding. It is within the scope of knowledge that can be clearly understood by those skilled in the art.

[0025] The working principle of this utility model is as follows: In the idle position of this device, all the aforementioned driving components (representing power elements, electrical devices, and compatible power supplies) are connected via wires. The electrical connections are completed in sequence between the working components. The detailed connection methods are well-known in the field. The following mainly describes the working principle and process, without further explanation of the electrical control. Installation and fixing device: Wrap the binding strap 7 around the utility pole 1, while ensuring the arc-shaped fixing ring 8 is tightly against the opposite side of the utility pole 1. The hook 10 at one end of the binding strap 7 is hooked onto the hook post 11 at the end of the arc-shaped fixing ring, forming a closed loop.

[0026] Operate the handle of the ratchet tensioner 6 to tighten the strap 7 through the one-way locking mechanism of the ratchet and pawl, so that the device is securely tied to the utility pole 1.

[0027] Connecting the backup safety rope: One end of the backup safety rope 12 is tied to the waist of the worker, and the other end is hooked to the connecting ring 14 in the middle of the arc-shaped fixed ring through the elastic hook 13; the connecting ring 14 is welded to the arc-shaped fixed ring 8 through the connecting block 15.

[0028] The spring latch of the elastic hook 13 automatically closes the main lock of the hook door, and the secondary lock is manually rotated to achieve double-safe locking.

[0029] Work safety: Workers work on the insulated platform 3, which is fixed to the utility pole by the platform fixing frame 2 and is equipped with a guard bar 4 to provide hand support.

[0030] When workers move, the backup safety rope 12 remains taut because it is directly fixed to the utility pole 1; in the event of a slip, the device provides a rigid limit to prevent a fall from the platform.

[0031] Disassembly and adjustment: Press the release lever of the ratchet tensioner 6 to disengage the pawl from the ratchet, allowing the strap 7 to be released freely, facilitating disassembly or position adjustment of the device.

[0032] The entire process ensures that the backup safety rope is always taut, achieving dual protection of "work positioning + fall protection".

[0033] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

[0034] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
