Description

Technical Field

[0001] The utility model relates to the technical field of protection fitting equipment, in particular to a high-strength protection fitting for overhead power lines. Background Technique

[0002] The iron or aluminum metal accessories widely used in transmission lines are collectively called fittings. There are various types of fittings with different uses. They are related to the safety of conductors or towers. Even if one is damaged, it may cause line failures.

[0003] After retrieval, the application number 202221906961.5 discloses a high-strength protection fitting for overhead power lines, including a main body. A protective layer is arranged at the upper end of the main body. A connecting column is fixedly installed in the middle of the rear end of the main body. Pillars are arranged in the middle of the left end and the right end of the main body respectively. Clamps are fixedly installed at the left end and the right end of the two pillars respectively. The two pillars are symmetrically distributed left and right. A wear-resistant layer is arranged on the outer surface of the main body. An anti-corrosion layer is arranged on the outer surface of the wear-resistant layer.

[0004] During the use of a high-strength protection fitting for overhead power lines in the patent application, the position of the clamp is adjusted by adjusting the position of the pillar inside the connecting groove, and then the position between the pillar and the main body is fixed by passing a limit pin through the perforation and inserting it into the screw groove at the same time. However, during such use, since the adjustment of the position of the clamp by this device is limited by the position of the screw groove, the device cannot freely adjust the position of the clamp, reducing the practicability of the device. Therefore, we propose a high-strength protection fitting for overhead power lines. Content of the Utility Model

[0005] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a high-strength protection fitting for overhead power lines.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme. A high-strength protection fitting for overhead power lines includes a device main body, a fixing component arranged on the rear wall surface of the device main body, and two clamping components symmetrically arranged on the left and right sides of the device main body. A connecting through groove is penetrated and opened inside the device main body. A connecting mechanism is arranged inside the connecting through groove. The connecting mechanism includes two connecting supports slidably connected to the left and right ends inside the connecting through groove. The two clamping components are respectively fixedly connected to the ends of the two connecting supports away from each other. An adjusting mechanism for driving the two connecting supports to move left and right is arranged inside the connecting through groove. The adjusting mechanism includes two adjusting threaded rods rotatably connected to the inside of the connecting through groove and two adjusting worm wheels fixedly installed at the ends of the two adjusting threaded rods close to each other.

[0007] Furthermore, two mounting support plates are symmetrically and fixedly installed in the middle of the inner cavity of the connection through groove, and are rotationally connected to the outer wall surfaces of the mutually approaching ends of the two adjusting threaded rods.

[0008] Furthermore, two adjusting threaded holes adapted to the outer wall surfaces of the two adjusting threaded rods are provided on the mutually approaching surfaces of the two connection supports, and the mutually remote ends of the two adjusting threaded rods are respectively threadedly connected to the interiors of the two adjusting threaded holes.

[0009] Furthermore, two adjusting worms that mesh with the bottoms of the two adjusting worm wheels are rotationally connected in the middle of the inner cavity of the connection through groove.

[0010] Furthermore, two storage grooves corresponding to the positions of the two adjusting worms are provided on the front wall surface of the equipment main body.

[0011] Furthermore, the front wall surfaces of the two adjusting worms penetrate through the front inner wall surface of the connection through groove and extend into the two storage grooves, and hexagonal grooves are provided at the front ends of the two adjusting worms.

[0012] Furthermore, limiting sliding grooves are provided on the front and rear side wall surfaces of the two connection supports, and four limiting sliding blocks that are slidably connected to the interiors of the four limiting sliding grooves are fixedly installed on the front and rear inner wall surfaces of the connection through groove.

[0013] Beneficial Effects

[0014] The utility model provides a high-strength protection fitting for overhead power lines. The following beneficial effects are achieved:

[0015] 1. For the high-strength protection fitting for overhead power lines, by providing a connection mechanism and an adjustment mechanism, during use, the device can be easily fixed and installed at a specified position through the fixing component. When the position of the clamping component needs to be adjusted, a hexagonal wrench is inserted into the hexagonal groove to drive the adjustment worm to rotate, forcing the adjustment worm wheel threadedly connected to the outer wall surface of the adjustment worm to drive the adjustment threaded rod to rotate. Furthermore, the connection support threadedly connected to the outer wall surface of the adjustment threaded rod through the adjustment threaded hole drives the clamping component to move left and right along the inside of the connection through groove to be adjusted to a suitable position. The above operations are simple and practical, and the structure is reasonable and compact, enabling the device to freely and conveniently adjust the position of the clamping component and improving the practicability of the device.

[0016] 2. For the high-strength protection fitting for overhead power lines, by providing limiting sliding grooves and limiting sliding blocks, when the position of the clamping component is adjusted by adjusting the position of the connection support inside the connection through groove, the connection support is slidably connected to the side wall surface of the inner cavity of the connection through groove through the limiting sliding grooves and limiting sliding blocks, enhancing the connection between the connection support and the equipment main body and improving the structural stability of the device.
