Description

Technical Field

[0001] This utility model relates to the technical field of power transmission and transformation equipment, specifically to a parallel trench clamp for power transmission and transformation. Background Technology

[0002] Parallel groove clamps are used for connecting small and medium cross-section aluminum stranded wires or steel-cored aluminum stranded wires and steel stranded wires of overhead lightning protection wires in positions where they are not subjected to tension. They are also used for jumper connections on non-straight towers and are mainly used in power transmission and transformation line projects.

[0003] Traditional bolt-type parallel groove clamps use a plate-to-plate structure, relying on the tightening pressure of bolts to fix the connecting wires in the upper and lower grooved clamps to complete the connection. Traditional bolt-type parallel groove clamps have the following problems during use: the cover plate is connected to the base plate by bolts, and the cover plate is prone to rotation and displacement during the clamping process, requiring repeated adjustments to avoid misalignment. At the same time, they can only clamp cables of a single diameter. Utility Model Content

[0004] In order to overcome the problems in the background technology, this utility model provides a parallel groove clamp for power transmission and transformation, which solves the problem that in the use of traditional bolt-type parallel groove clamps, the cover plate is connected to the base plate by bolts, the cover plate is easy to rotate and shift during the clamping process, and repeated adjustments are required to avoid misalignment. It can only clamp cables of a single diameter.

[0005] A parallel groove clamp for power transmission and transformation includes a pressure plate, a pressure cover, and fastening bolts. The pressure cover is evenly spaced and spliced ​​on the upper part of the pressure plate. The pressure cover is installed to the pressure plate by fastening bolts. The pressure cover is M-shaped, with semi-arc pressure grooves on both sides and a limiting block in the middle. The pressure plate is provided with pressure grooves corresponding to the first pressure groove and limiting grooves corresponding to the limiting block.

[0006] Furthermore, the sidewalls on both sides of the pressure cap extend vertically downwards to cover both sides of the pressure plate to form a limiting plate.

[0007] Furthermore, a pressure plate and a gasket are sequentially installed between the pressure cap and the fastening bolt.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This application includes a pressure plate and a pressure cover. The pressure cover has a limiting block in the middle, and the pressure plate has a limiting groove corresponding to the limiting block, so that the position corresponds during the pressing process. This solves the problem that in the traditional bolt-type parallel groove clamp, the cover plate is connected to the base plate by bolts, and the cover plate is prone to rotation and displacement during the pressing process, requiring repeated adjustments to avoid misalignment. In this application, the side walls on both sides of the pressure cover extend vertically downward to cover both sides of the pressure plate to form a limiting plate, which can move up and down to adjust the spacing of the pressing grooves to press cables of different diameters. This solves the problem that the traditional bolt-type parallel groove clamp can only press cables of a single diameter. Attached Figure Description

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0016] This utility model proposes a parallel trench clamp for power transmission and transformation, see reference. Figure 1-3 A parallel groove clamp for power transmission and transformation includes a pressure plate 1, a pressure cover 2, and fastening bolts 3. The pressure cover 2 is evenly spaced and spliced ​​on the upper part of the pressure plate 1. The pressure cover 2 is installed to the pressure plate 1 by fastening bolts 3. The pressure cover 2 is M-shaped. The two sides of the pressure cover 2 are semi-arc pressure grooves 21. The middle of the pressure cover 2 is a limiting block 22. The pressure plate 1 is provided with a pressure groove 11 corresponding to the pressure groove 21 and a limiting groove 12 corresponding to the limiting block 22.

[0017] The pressure grooves 1 21 and 2 11 on both sides of the pressure plate 1 and the pressure cover 2 can press the cable tightly. The fastening bolts 3 can fasten the pressure plate 1 and the pressure cover 2. The limiting block 22 on the pressure cover 2 can cooperate with the limiting groove 12 to avoid the problem of deflection during the pressing process of the pressure cover 2.

[0018] See Figure 1-3The side walls of the pressure cover 2 extend vertically downward to cover both sides of the pressure plate 1 to form a limiting plate 23, which can move up and down to adjust the spacing of the pressure grooves to press cables of different diameters.

[0019] See Figure 1-3 A pressure plate 4 and a gasket 5 are sequentially installed between the pressure cap 2 and the fastening bolt 3 to provide uniform and constant pressure.

[0020] Work process:

[0021] Place the cable in the pressure groove 11, cover it with the pressure cover 2 and place the pressure plate 4 and the gasket 5. Press down the pressure cover 2 by rotating the fastening bolt 3. During the pressing process, the limiting block 22 cooperates with the limiting groove 12. The limiting plate 23 prevents the cable from being exposed, thus completing the cable fixing.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
