A power transmission line clamp with wear-resistant structure

Abstract

This utility model belongs to the field of power transmission line clamp technology, and in particular to a power transmission line clamp with an anti-wear structure. It includes two clamp bodies, each with an inner clamp cavity for restricting the power line. Two outer spacers are fixedly connected within each inner clamp cavity, and a hollow area exists between the two outer spacers. Two wear-resistant rubber rings are disposed within the hollow area. Each clamp body has a movable cavity corresponding to the wear-resistant rubber rings, and a compression space elastic ring is disposed within the movable cavity to restrict the position of the wear-resistant rubber rings. The clamp, with its inner wear-resistant rubber pad, not only buffers vibration but also prevents hard friction between the metal clamp and the conductor or tower. Furthermore, the position of the compression space elastic ring can be adjusted according to the compression amount at the point where the wear-resistant rubber ring contacts the outer wall of the power line, thus restricting the position of the wear-resistant rubber ring and preventing it from exceeding its compression limit, which would reduce its effectiveness.

Description

Technical Field

[0001] This utility model belongs to the field of power transmission line clamp technology, specifically relating to a power transmission line clamp with an anti-wear structure. Background Technology

[0002] A power transmission line clamp is a device used to tighten and fix power transmission lines. When power transmission lines are installed on utility poles, clamps are needed to fix the power transmission lines so that the power transmission lines are stably installed on the utility poles. When using the device, simply clamp the clamp onto the power transmission line.

[0003] When clamps are attached to power transmission lines, their internal diameter forces them to hold the line tightly. This direct contact between the clamp's interior and the line can cause wear and tear, thus affecting the lifespan of the power transmission line. Utility Model Content

[0004] This utility model provides a power transmission line clamp with an anti-wear structure, which not only buffers vibration and prevents hard friction between the metal clamp and the conductor or tower, but also allows for adjustment of the position of the elastic ring in the compression space according to the amount of compression at the contact point of the wear-resistant rubber ring with the outer wall of the conductor. This restricts the position of the wear-resistant rubber ring and avoids exceeding the compression degree of the wear-resistant rubber ring, thus preventing a reduction in its performance.

[0005] This utility model provides the following technical solution: a power transmission line clamp with an anti-wear structure, comprising two clamp bodies, each clamp body having an inner clamp cavity for restricting the cable body, two outer spacers fixedly connected within the inner clamp cavity, a hollow area between the two outer spacers, and two wear-resistant rubber rings disposed within the hollow area, each clamp body having a movable cavity corresponding to the wear-resistant rubber rings, and a compression space elastic ring disposed within the movable cavity for restricting the position of the wear-resistant rubber rings, the position of the compression space elastic ring being adjusted according to the compression amount by the wear-resistant rubber rings contacting the outer wall of the cable body.

[0006] The hoop has mounting bases fixedly connected to both sides, and the mounting bases are connected by bolts.

[0007] The active cavity is open on the side opposite to the wear-resistant rubber ring, and the wear-resistant rubber ring is located outside the elastic ring of the compression space.

[0008] The hoop is threaded with several limiting bolts, one end of which contacts the outer side of the elastic ring in the compression space.

[0009] The outer spacer ring has a heat insulation layer on its outer side, and the heat insulation layer is filled with rock wool.

[0010] The wear-resistant rubber ring has an inner diameter smaller than the inner diameter of the outer spacer, and the wear-resistant rubber ring is located inside the inner hoop cavity.

[0011] The hollow region is separated by two outer spacers, and the hollow region is away from the outer surface of the line.

[0012] The beneficial effects of this utility model are:

[0013] Two outer spacers are fixedly connected inside the inner clamp cavity, with a hollow area between them. Two wear-resistant rubber rings are installed in the hollow area. The wire body is restricted by the wear-resistant rubber rings. The clamp with wear-resistant rubber pads embedded on the inside can not only buffer vibration, but also prevent hard friction between the metal clamp and the conductor or tower. At the same time, the position of the elastic ring in the compression space can be adjusted according to the amount of compression at the contact point of the wear-resistant rubber ring with the outer wall of the wire body. That is, the position of the wear-resistant rubber ring is restricted, which can prevent the wear-resistant rubber ring from being compressed beyond its degree and reducing its effectiveness.

[0014] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] Please see Figures 1-4 The present invention provides the following technical solution: it includes two hoop bodies 1, each of which has an inner hoop cavity 11 for limiting the yarn body. Two outer spacers 12 are fixedly connected in the inner hoop cavity 11. There is a hollow area 15 between the two outer spacers 12. Two wear-resistant rubber rings 13 are provided in the hollow area 15. The hoop body 1 has a movable cavity 101 corresponding to the wear-resistant rubber rings 13. The movable cavity 101 has a compression space elastic ring 3 for limiting the position of the wear-resistant rubber rings 13. The position of the compression space elastic ring 3 is adjusted according to the compression amount by the wear-resistant rubber rings 13 contacting the outer wall of the yarn body.

[0021] In this embodiment: two outer spacers 12 are fixedly connected inside the inner hoop cavity 11, with a hollow area 15 between the two outer spacers 12. Two wear-resistant rubber rings 13 are installed in the hollow area 15. Mounting seats 14 are fixedly connected to both sides of the hoop body 1, and the mounting seats 14 are connected by bolts. When in use, the two hoop bodies 1 can be mated to the outside of the line body and fixed by connecting bolts. Simultaneously, the wear-resistant rubber rings 13 can contact the outer wall of the line body. The hoop body 1 has a movable cavity 101 corresponding to the wear-resistant rubber rings 13. The movable cavity 101 contains a compression space elastic ring 3 for limiting the position of the wear-resistant rubber rings 13. The compression space elastic ring 3 is adjusted according to the compression amount when the wear-resistant rubber rings 13 contact the outer wall of the line body. Before use, the outer diameter of the wire to be restricted can be measured, and the degree of compression can be analyzed based on the inner diameter of the wear-resistant rubber ring 13. If the degree of compression is too large or too small, the position of the elastic ring 3 in the compression space can be changed. The wear-resistant rubber ring 13 contacts and restricts the wire, and the clamp with the wear-resistant rubber pad embedded on the inside can not only buffer vibration, but also prevent hard friction between the metal clamp and the conductor or tower. At the same time, the position of the elastic ring 3 in the compression space can be adjusted according to the amount of compression based on the contact point of the wear-resistant rubber ring 13 with the outer wall of the wire. That is, the position of the wear-resistant rubber ring 13 can be restricted to avoid exceeding the compression degree of the wear-resistant rubber ring 13 and reducing the effectiveness of the wear-resistant rubber ring 13.

[0022] The side of the movable cavity 101 opposite to the wear-resistant rubber ring 13 is open. The wear-resistant rubber ring 13 is located outside the compression space elastic ring 3. Several limiting bolts 2 are threaded on the hoop 1. One end of the limiting bolt 2 contacts the outside of the compression space elastic ring 3. The position of the compression space elastic ring 3 in the movable cavity 101 can be changed by the limiting bolt 2. The outer wall of the limiting bolt 2 can be locked with a nut. If the wear-resistant rubber ring 13 is compressed to a large degree, the limiting bolt 2 can be adjusted to the outside, that is, the compression space elastic ring 3 can move into the movable cavity 101. If the degree of compression is small, the operation can be reversed.

[0023] The outer spacer ring 12 has a heat insulation layer on the outside, and the heat insulation layer is filled with rock wool. The outer spacer ring 12 protects the wear-resistant rubber ring 13, increases its service life, reduces the phenomenon of high-temperature aging of the wear-resistant rubber ring 13, and avoids easily affecting the clamp's holding force.

[0024] The inner diameter of the wear-resistant rubber ring 13 is smaller than the inner diameter of the outer spacer 12. The wear-resistant rubber ring 13 is located inside the inner hoop cavity 11. When the hoop body 1 is in use, the two hoop bodies 1 can be connected to the outer side of the line body and the two hoop bodies 1 can be fixed by connecting bolts. At the same time, the wear-resistant rubber ring 13 can contact the outer wall of the line body.

[0025] The hollow area 15 is separated by two outer spacers 12, and the hollow area 15 is far away from the outer surface of the yarn body; the two wear-resistant rubber rings 13 are set separately to reduce the contact points and further reduce the occurrence of wear on the yarn body.

[0026] The working principle and usage of this utility model are as follows: Mounting seats 14 are fixedly connected to both sides of the hoop 1, and the mounting seats 14 are connected by bolts. When using the hoop 1, two hoop 1s can be joined together on the outer side of the line body and fixed by connecting bolts. Simultaneously, the wear-resistant rubber ring 13 can contact the outer wall of the line body. The hoop 1 has a movable cavity 101 corresponding to the wear-resistant rubber ring 13. The movable cavity 101 contains a compression space elastic ring 3 for restricting the position of the wear-resistant rubber ring 13. The position of the compression space elastic ring 3 is adjusted according to the compression amount at the point where the wear-resistant rubber ring 13 contacts the outer wall of the line body. Before use, the required restriction of the line body can be measured. The outer diameter is determined by analyzing the degree of compression based on the inner diameter of the wear-resistant rubber ring 13. If the degree of compression is too large or too small, it can be achieved by changing the position of the elastic ring 3 in the compression space. The wear-resistant rubber ring 13 contacts and restricts the wire body, so that the clamp with the wear-resistant rubber pad embedded on the inner side can not only buffer vibration, but also prevent hard friction between the metal clamp and the conductor or tower. At the same time, the position of the elastic ring 3 in the compression space can be adjusted according to the amount of compression based on the contact point of the wear-resistant rubber ring 13 with the outer wall of the wire body. That is, the position of the wear-resistant rubber ring 13 is restricted, which can avoid exceeding the compression degree of the wear-resistant rubber ring 13 and reducing the effectiveness of the wear-resistant rubber ring 13.
