Description

Technical Field

[0001] This utility model relates to the technical field of fall protection mechanisms, and in particular to a fall protection mechanism for climbing ultra-high voltage transmission line towers. Background Technology

[0002] Transmission line towers are tower structures used to support and suspend conductors, lightning protection wires, and other accessories, ensuring that a prescribed safe distance is maintained between conductors, between conductors and towers, between conductors and lightning protection wires, and between conductors and the ground or objects they cross.

[0003] However, in existing technologies, tower workers often use ropes to assist in climbing towers. Rope-assisted climbing is quite strenuous and prone to swaying in the air, posing a high risk. Therefore, we propose a fall protection mechanism for climbing UHV transmission line towers. Utility Model Content

[0004] This utility model provides a fall prevention mechanism for climbing ultra-high voltage transmission line towers, which solves the above-mentioned technical problems.

[0005] The present invention provides the following solution to the above-mentioned technical problems: A fall prevention mechanism for climbing ultra-high voltage transmission line towers, comprising an arc-shaped kit, wherein grooves are respectively provided on the inner sidewalls of both sides of the arc-shaped kit, and one-way rotating parts are respectively installed on the inner sidewalls of the grooves at an incline. A limiting block is fixedly installed on the surface of the arc-shaped kit on the lower surface of the one-way rotating part. An auxiliary fixing part is rotatably installed on the outer wall of the arc-shaped kit. A fixing groove that fits with the auxiliary fixing part is provided on the outer side of the one-way rotating part. A limiting groove is fixedly installed on the outer sidewall of the arc-shaped kit. An L-shaped limiting part is slidably installed on the inner wall of the limiting groove. The limiting part slides with the outer wall of the auxiliary fixing part. The bottom surface of the limiting groove is connected to the limiting part through an elastic mechanism.

[0006] The elastic mechanism includes a first telescopic rod that is vertically fixedly installed on the bottom surface of the limiting groove. The upper end of the first telescopic rod is fixedly connected to the limiting member, and a first spring is movably sleeved on the outer wall of the first telescopic rod.

[0007] A second telescopic rod is vertically fixedly installed on the top surface of the groove, a pressing block is fixedly installed at the lower end of the second telescopic rod, and a second spring is movably sleeved on the outer wall of the second telescopic rod.

[0008] A telescopic sealing gasket is vertically fixedly installed on the outer edge of the bottom surface of the limiting groove.

[0009] Two connecting rings are fixedly installed at the lower part of one end of the arc-shaped kit.

[0010] The beneficial effects of this utility model are:

[0011] 1. By setting up an arc-shaped kit in conjunction with a one-way rotating component, the tower beam can be enclosed. At the same time, the one-way rotating component is limited by a second spring, ensuring the stable connection of the device on the tower beam and making it easier to open the one-way rotating component, making the climbing of the tower safer and more reliable for tower workers.

[0012] 2. By setting auxiliary fixing parts and limiting parts, when the tower workers climb to the target height, the auxiliary limiting parts can be rotated downwards to engage with the fixing groove of the one-way rotating parts, and the limiting parts can be used to limit the auxiliary fixing parts, preventing the one-way rotating parts from deflecting due to accidental contact during the operation and opening the gap, thus reducing safety risks.

[0013] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] The following is in conjunction with the appendix Figure 1-3The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0021] like Figure 1-3 As shown, this utility model discloses a fall prevention mechanism for climbing ultra-high voltage transmission line towers, comprising an arc-shaped component 1. Two connecting rings 15 are fixedly installed at the lower part of one end of the arc-shaped component 1. Multiple connecting rings 15 are provided to connect and install multiple steel cables, improving safety. Grooves 2 are respectively formed on the inner sidewalls of both sides of the arc-shaped component 1. One-way rotating parts 3 are respectively installed obliquely and rotatably on the inner sidewalls of the grooves 2. Limiting blocks 4 are fixedly installed on the surface of the arc-shaped component 1 on the lower surface of the one-way rotating parts 3. An auxiliary fixing part 5 is rotatably installed on the outer wall of the arc-shaped component 1. A fixing groove 6 that fits into the auxiliary fixing part 5 is formed on the outer side of the one-way rotating part 3. The outer wall of the arc-shaped component 1... A limiting groove 7 is fixedly installed, and a telescopic sealing gasket 14 is vertically fixedly installed on the outer edge of the inner bottom surface of the limiting groove 7. The telescopic sealing gasket 14 can be fitted. An L-shaped limiting component 8 is slidably installed on the inner wall of the limiting groove 7. The limiting component 8 slides with the outer wall of the auxiliary fixing component 5. The inner bottom surface of the limiting groove 7 is connected to the limiting component 8 through an elastic mechanism. This device uses a rotatable one-way rotating component 3 to fit with the arc-shaped kit 1 to connect with the iron tower beam. The auxiliary fixing component 5 and the limiting component 8 are set up for multiple limiting fixation, making the limiting fixation of the device more reliable and safer. At the same time, the spring provides force for the limiting, making the disassembly of the device more convenient.

[0022] Specifically, the elastic mechanism includes a first telescopic rod 9 vertically fixedly installed on the bottom surface of the limiting groove 7. The upper end of the first telescopic rod 9 is fixedly connected to the limiting member 8. A first spring 10 is movably sleeved on the outer wall of the first telescopic rod 9. The first telescopic rod 9, together with the first spring 10, ensures that the limiting member 8 and the upper part of the auxiliary fixing member 5 are tightly fitted and limited, indirectly ensuring the limiting and fixing of the unidirectional rotating member 3, preventing the unidirectional rotating member 3 from rotating open, and improving safety.

[0023] More specifically, a second telescopic rod 11 is vertically fixedly installed on the top surface of the groove 2, and a pressing block 12 is fixedly installed at the lower end of the second telescopic rod 11. A second spring 13 is movably sleeved on the outer wall of the second telescopic rod 11. The second telescopic rod 11 provides an installation base for the second spring 13. The second spring 13 pushes the pressing block 12 downward, and the pressing block 12 is used to press the unidirectional rotating part 3. The other two unidirectional rotating frames can be tightly fitted to prevent the iron tower beam from coming out of the arc-shaped kit 1 and ensure the stable connection between the device and the iron tower beam.

[0024] Working principle:

[0025] In use, rotate the one-way rotating part 3 inward towards the groove 2, increasing the distance between the other two one-way rotating parts 3. Then, the device can be fitted onto the tower beam through the gap between the two one-way rotating parts 3. Next, release the one-way rotating part 3, and the first spring 10 pushes the pressing block 12 to move. The pressing block 12 pushes the one-way rotating part 3 to rotate and reset, and the two one-way rotating parts 3 fit together. Then, press down on the limiting part 5, and then rotate the fixing part 5 downward so that the fixing part 4 engages with the fixing groove 6 of the one-way rotating part 3. Then, release the limiting part 8, and the limiting part 8 moves upward and resets under the push of the second spring 13, limiting and fixing the auxiliary fixing part 5, thus completing the installation.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
