Description

Technical Field

[0001] This utility model relates to the field of safety rope attachment technology, and in particular to a safety rope attachment device for power transmission towers. Background Technology

[0002] In the operation and maintenance of power transmission towers, ensuring the safety of workers climbing the towers is of paramount importance. Currently, many in-service towers were not designed with safety rope devices in mind. This means that when workers climb such towers, the first climber must ascend to the top alone with a safety rope, without the protection of a fall arrestor system. After manually securing the safety rope to the angle steel at the top of the tower, they must lower it for subsequent workers to use. After the work is completed, the last person to descend the tower must retrieve the safety rope and bring it back to the base. During this process, the first climber and the last descender face significant safety risks due to the lack of fall arrestor protection.

[0003] While there are technical solutions on the market that rely on drones to automatically attach and attach safety fixing devices, these devices generally suffer from poor integration. They are often composed of multiple mechanisms, have low integration, are cumbersome to install, and are highly complex to operate. The drone usually needs to be attached to multiple mechanisms to complete the attachment action. This is not only inconvenient to operate when installing and connecting on the ground, but also affects the drone's flight and the overall attachment action in narrow working environments.

[0004] To address the aforementioned issues, this technical solution provides a safety rope retrieval device for power transmission towers. The device is carried by a drone, which uses a hook at its bottom to attach to a lifting ring at the top of the retrieval device's main body. The device is then transported to a suitable location on the power transmission tower. Upon arrival, the drone descends, aligning the retrieval device with the tower's angle steel. The device's own weight causes two hook plates to engage with the angle steel, forming a self-locking structure. This ensures the retrieval device is stably fixed to the angle steel, capable of withstanding the weight of personnel suspended on the safety rope and a certain amount of swaying impact load. This safety rope retrieval device effectively improves overall integrity, simplifies drone retrieval operations, and enhances operational efficiency and safety. Utility Model Content

[0005] The purpose of this utility model is to provide a safety rope hook and release device for power transmission towers. After the entire structure reaches the designated position, the main body of the hook and release device forms a self-locking mechanism with the angle steel based on its own weight, which makes it convenient for operators to quickly hook and release the safety rope, thereby improving work efficiency and safety.

[0006] The technical implementation scheme of this utility model is as follows:

[0007] A safety rope hook for power transmission towers includes a main base, a pull plate, a main pin, a pull ring, and a self-locking structure. The main base has a connecting hole inside, and the main pin is movably mounted inside the connecting hole, connecting to the self-locking structure. The self-locking structure includes a first connecting rod, a second connecting rod, a first swing arm, a second swing arm, a first limiting plate, and a second limiting plate. The first swing arm is movably mounted on a first rotating shaft of the main base, and one end of the first swing arm is connected to a first pin on the main pin via the first connecting rod. The second swing arm is movably mounted on a second rotating shaft of the main base, and one end of the second swing arm is connected to a first pin on the main pin via the second connecting rod. A first limiting plate is located at the lower part of the first swing arm, a second limiting plate is located at the lower part of the second swing arm, and a limiting ring is located on one side of the second swing arm.

[0008] Optionally, a first sliding groove is provided at one end of the first connecting rod, and the first sliding groove is movably connected to a first pin on the first swing arm; a second sliding groove is provided at the upper part of the second connecting rod, and the second sliding groove is movably connected to a second pin on the second swing arm; a limiting ring is provided at the junction of the surface of the limiting ring and the bottom of the second connecting rod.

[0009] Optionally, an auxiliary wheel is provided on one side of the first swing arm and the second swing arm.

[0010] Optionally, the main pin is connected to the connecting hole of the main body base via a linear bearing.

[0011] Optionally, the first and second rotating shafts are connected to the through holes of the main body base, and a bearing is provided at the connection between the through hole and the rotating shaft.

[0012] Optionally, the second limiting plate is an L-shaped locking strip structure, and the first limiting plate is a rectangular cavity structure with openings at both ends and one side; a safety rope hanging hole is provided on the upper part of the pull plate.

[0013] Optionally, the pull ring is connected to the upper part of the main pin shaft.

[0014] This utility model has the following advantages:

[0015] 1. In this utility model, a main pin is provided inside the connecting hole of the entire main base, and the first pin at the top of the main pin is rotatably connected to the first swing arm and the second swing arm through the first connecting rod and the second connecting rod respectively. Under this structure, the rotation of the first swing arm and the second swing arm can be driven by the lifting and lowering of the main pin, and then the entire structure is locked on the iron tower square steel by the first limiting plate and the second limiting plate at the bottom, thereby realizing self-locking.

[0016] 2. In use, when the main base rests on the square steel, the main pin shaft is raised and lowered by its own gravity, thereby achieving self-locking. This allows it to be used in conjunction with drones, making it convenient for operators to attach safety ropes when repairing iron towers. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0025] like Figures 1-6As shown, a safety rope hook for power transmission towers includes a main base 1, a pull plate 2, a main pin 3, a pull ring 4, and a self-locking structure 5. The main base 1 has a connecting hole 7 inside, and the main pin 3 is movably mounted inside the connecting hole 7, connecting to the self-locking structure 5. The self-locking structure 5 includes a first connecting rod 501, a second connecting rod 502, a first swing arm 505, a second swing arm 504, a first limiting plate 506, and a second limiting plate 514. The first swing arm 505 is movably mounted on a first rotating shaft 510 of the main base 1, and one end of the first swing arm 505 is connected to a first pin 503 on the main pin 3 via the first connecting rod 501. The second swing arm 504 is movably mounted on a second rotating shaft 509 of the main base 1. The first swing arm 504 is connected at one end to the first pin 503 on the main pin 3 via the second connecting rod 502; the lower part of the first swing arm 505 is provided with a first limiting plate 506, the lower part of the second swing arm 504 is provided with a second limiting plate 514, and a limiting ring 513 is provided on one side of the second swing arm 504; one end of the first connecting rod 501 is provided with a first sliding groove 511, and the first sliding groove 511 is movably connected to the first pin 512 on the first swing arm 505; the upper part of the second connecting rod 502 is provided with a second sliding groove 507, and the second sliding groove 507 is movably connected to the second pin 508 on the second swing arm 504; the limiting ring 513 is provided at the junction of its surface and the bottom of the second connecting rod 502.

[0026] It should be noted that, in order to facilitate the drone to lift the entire mechanism onto the iron tower in the store, a main pin 3 is movably installed in the connecting hole 7 on the main base 1. A first pin 503 is installed on the upper part of the main pin 3, and a first connecting rod 501 and a second connecting rod 502 are installed on the first pin 503.

[0027] It should be further explained that during operation, when the entire mechanism is lifted by the drone, the main pin 3 can be stretched upwards due to its own gravity. Based on the first link 501 and the second link 502, the first swing arm 505 and the second swing arm 504 are driven to swing. The two bottom first limit plates 506 and the second limit plates 514 are in the open state, as shown in the attached diagram. Figure 5 and attached Figure 6As shown; when the entire mechanism reaches the corresponding position, the main base 1 will contact the angle steel 6. At this time, the main pin 3 will move downward due to its own weight, thereby driving the first limit plate 506 and the second limit plate 514 to self-lock with the angle steel 6, so that the staff can hang the safety rope.

[0028] like Figures 1-6 As shown, an auxiliary rotating wheel 515 is provided on one side of the first swing arm 505 and the second swing arm 504; the main pin shaft 3 is connected to the connecting hole 7 of the main body base 1 through the linear bearing 8; the first rotating shaft 510 and the second rotating shaft 509 are connected to the through hole 10 of the main body base 1, and a bearing is provided at the connection between the through hole 10 and the rotating shaft.

[0030] like Figures 1-6 As shown, the second limiting plate 514 is an L-shaped locking strip structure, and the first limiting plate 506 is a rectangular cavity structure with openings at both ends and one side; the upper part of the pull plate 2 is provided with a safety rope hanging hole 9; the pull ring 4 is connected to the upper part of the main pin 3.

[0031] It should be noted that the second limiting plate 514 can be locked at the angle steel 6 in conjunction with the first limiting plate 506 to form a self-locking structure.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings.
