Description

Technical Field

[0001] This utility model relates to the field of suspension clamp technology, specifically a suspension clamp for power transmission and distribution lines. Background Technology

[0002] Overhead power transmission lines consist of poles, conductors, insulators, line hardware, guy wires, pole foundations, and grounding devices, and are erected above the ground. Based on the nature of the transmitted current, power transmission is divided into AC transmission and DC transmission. Suspension clamps are key hardware in power lines, mainly used to fix overhead conductors, ensuring their stability on straight poles and bearing the vertical load of the conductors.

[0003] In existing technology, suspension clamps consist of a U-shaped channel, a clamping block, two U-bolts, and two hanging plates. The conductor is placed in the U-shaped channel and held in place by the clamping block. The two U-bolts pass through the side holes of the U-shaped channel and are tightened with nuts. The two hanging plates are then connected to the U-shaped channel using bolt sets, facilitating subsequent hanging of the U-shaped channel. However, in actual use, the suspension clamp assembly must be performed in the air, requiring the assembly of multiple components and the alternating tightening of the U-bolts on both sides (at least four tightening actions). This results in a long working time and cumbersome operation. Therefore, an improved suspension clamp for power transmission and distribution lines is needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a suspension clamp for power transmission and distribution lines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a suspension clamp for power transmission and distribution lines, comprising a U-shaped groove and a scraper, wherein a first anti-slip pad is provided on the bottom inner wall of the U-shaped groove, a positioning mechanism is provided inside the scraper, and a limiting mechanism is provided outside the U-shaped groove.

[0006] Preferably, the positioning mechanism includes a horizontal plate, which is slidably installed inside the scraper. Blocks are fixedly installed on both the front and back of the horizontal plate. A vertical plate is fixedly installed at the end of the horizontal plate away from the scraper. A pressure block is fixedly installed at the bottom of the vertical plate. A second anti-slip pad is provided at the bottom of the pressure block. A first stud is movably installed inside the scraper. A nut is installed on the external thread of the first stud. A cotter pin is inserted inside the first stud. A positioning cylinder is sleeved on the outside of the first stud. By completing the assembly of the scraper and pressure block before high-altitude operations, the time for subsequent high-altitude operations is shortened.

[0007] Preferably, the limiting mechanism includes a positioning block, which is fixedly installed on the outside of the U-shaped groove. A second stud is movably installed inside the positioning block. A threaded sleeve is fixedly installed inside the U-shaped groove. The second stud is threaded inside the threaded sleeve. A rubber pad is fixedly installed on the outside of the upright plate to facilitate the rapid positioning and limiting of the scraper, the upright plate and the pressure block.

[0008] Preferably, a groove is provided inside the positioning block at a position corresponding to the scraper, and the scraper is slidably installed in the groove to facilitate the positioning of the scraper.

[0009] Preferably, a through hole is provided inside the scraper at the position corresponding to the second stud, and the second stud passes through the through hole to facilitate the limiting operation of the scraper.

[0010] Compared with the prior art, this utility model provides a suspension clamp for power transmission and distribution lines, which has the following advantages:

[0011] 1. This suspension clamp for power transmission and distribution lines, through its positioning mechanism, facilitates the positioning of the scraper and horizontal plate during use by sliding the scraper and horizontal plate together with the cooperation of the stop block. This also facilitates the installation of the vertical plate and pressure block. With the cooperation of the second anti-slip pad, it increases the friction with the conductor. The positioning cylinder facilitates the positioning of the top distance between the two scrapers and the subsequent suspension clamp hanging operation. It also protects the first stud, making it less prone to deformation. By passing the first stud through the scraper and the positioning cylinder, and with the cooperation of the nut and cotter pin, it is convenient to complete the assembly of the scraper and pressure block before aerial work, thus shortening the time for aerial work.

[0012] 2. The suspension clamp used in this power transmission and distribution line, through the setting of the limiting mechanism, facilitates the quick positioning of the scraper by the setting of the positioning block during use, thereby facilitating the quick positioning of the upright plate and the pressure block. By passing the second stud through the positioning block and the scraper, it is convenient to limit the scraper. By rotating the second stud, with the cooperation of the threaded sleeve, the second stud can move towards the rubber pad, which can facilitate the compression of the rubber pad and the limiting of the upright plate and the pressure block. The operation is convenient and saves time. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Example 1:

[0023] Please see Figure 1-4 This utility model provides a technical solution: a suspension clamp for power transmission and distribution lines, including a U-shaped groove 1 and a scraper 2. A first anti-slip pad 3 is provided on the bottom inner wall of the U-shaped groove 1 to increase the friction between the U-shaped groove 1 and the conductor. A positioning mechanism 4 is provided inside the scraper 2, and a limiting mechanism 5 is provided outside the U-shaped groove 1.

[0024] Furthermore, the positioning mechanism 4 includes a horizontal plate 401, which is slidably installed inside the scraper 2. Stops 402 are fixedly installed on both the front and back of the horizontal plate 401. The stops 402 facilitate the positioning of the horizontal plate 401 and the positioning of the distance between the two scrapers 2. A vertical plate 403 is fixedly installed at the end of the horizontal plate 401 away from the scraper 2. Two horizontal plates 401 are symmetrically installed on the outside of the vertical plate 403 to facilitate its positioning. A pressure block 404 is fixedly installed at the bottom of the vertical plate 403. The bottom of the pressure block 404 has an arc-shaped groove for clamping the wire. A second anti-slip pad 4 is provided at the bottom of the pressure block 404. 05. With the cooperation of the second anti-slip pad 405, it is easy to increase the friction with the wire. The first stud 406 is movably installed inside the scraper 2. The nut 407 is installed on the external thread of the first stud 406. The cotter pin 408 is inserted inside the first stud 406 to limit the nut 407. The positioning cylinder 409 is sleeved on the outside of the first stud 406. The positioning cylinder 409 facilitates the positioning of the top distance between the two scrapers 2 and the subsequent suspension of the hanging clamp. It also protects the first stud 406 and makes it less prone to deformation. By completing the assembly of the scraper 2 and the pressure block 404 before high-altitude operation, the time for subsequent high-altitude operation is shortened.

[0025] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, the limiting mechanism 5 includes a positioning block 501, which is fixedly installed on the outside of the U-shaped groove 1. There are two positioning blocks 501, symmetrically arranged on the outside of the U-shaped groove 1. A second stud 502 is movably installed inside the positioning block 501. Two threaded sleeves 503 are fixedly installed inside the U-shaped groove 1, with their positions corresponding to the through holes of the positioning blocks 501. The second stud 502 is threadedly installed inside the threaded sleeve 503. The upright plate 40... Rubber pads 504 are fixedly installed on both the left and right sides of 3. The positioning block 501 facilitates the quick positioning of the scraper 2, thereby facilitating the quick positioning of the upright plate 403 and the pressure block 404. By passing the second stud 502 through the positioning block 501 and the scraper 2, the scraper 2 is easily limited. By rotating the second stud 502, with the cooperation of the threaded sleeve 503, the second stud 502 can move towards the rubber pad 504, facilitating the compression of the rubber pad 504 and the limiting of the upright plate 403 and the pressure block 404. The operation is convenient.

[0026] Furthermore, a groove is provided inside the positioning block 501 at the position corresponding to the scraper 2, and the scraper 2 is slidably installed in the groove, which facilitates the positioning of the scraper 2 and the initial positioning of the pressure block 404, thus completing the initial assembly of the U-shaped groove 1, the scraper 2 and the pressure block 404.

[0027] Furthermore, a through hole is provided inside the scraper 2 at the position corresponding to the second stud 502, and the second stud 502 passes through the through hole. The second stud 502 passes through the positioning block 501 and the scraper 2, which facilitates the quick positioning of the scraper 2 and the subsequent positioning of the upright plate 403, saving time.

[0028] In actual operation, when this device is used, the two scrapers 2 are slidably installed on the horizontal plate 401, so that the scrapers 2 contact the stop block 402. The positioning cylinder 409 is placed between the two scrapers 2. The first stud 406 is passed through the scraper 2 and the positioning cylinder 409, and the nut 407 is rotated to the outside of the first stud 406, so that the end face of the scraper 2 and the positioning cylinder 409 are in close contact. With the cooperation of the cotter pin 408, the assembly of the scraper 2 and the pressure block 404 is completed. When performing high-altitude operations, the wire is placed on the inner wall of the U-shaped groove 1, so that the wire contacts the first anti-slip pad 3, and the scraper 2 is slid into the positioning block 5. In the groove of 01, the second anti-slip pad 405 comes into contact with the wire, completing the initial positioning of the scraper 2 and the pressure block 404. By passing the second stud 502 through the positioning block 501 and the scraper 2, the scraper 2 is limited. By threading the second stud 502 and the threaded sleeve 503, and by pressing the upright plate 403, the second anti-slip pad 405 comes into close contact with the wire. The second stud 502 continues to rotate, causing the second stud 502 to squeeze the rubber pad 504, completing the limiting of the pressure block 404. The positioning cylinder 409 is hoisted by the hoisting assembly set on the utility pole, completing the installation of the suspension clamp.
