Annular grinding device used for surface of cable after cable insulation layer is stripped

Abstract

The invention relates to an annular grinding device used for the surface of a cable after a cable insulation layer is stripped. The annular grinding device comprises a main board, a fixed support, a grinder body and a power mechanism. The cable with the crosslinked polyethylene cable insulation layer stripped is clamped and fixed through the main board and the fixed support. The grinder body is mounted on the main board through bearings. The power mechanism is mounted on the main board and connected with the grinder body. A dustproof protection cover used for preventing dust from being diffused is further arranged on the main body. The dustproof protection cover wraps the grinder body and is connected to a dust collector. Compared with the prior art, the annular grinding device can clamp and grind the cable, and grinding stability can be improved.

Description

technical field [0001] The invention relates to a grinding device, in particular to an annular grinding device used for cable surface after the cable insulation layer is stripped. Background technique [0002] At present, for the continuous work of high-voltage cables or the installation of terminal cable accessories, the cables need to be stripped layer by layer according to the construction requirements. However, due to the high temperature of the cable production process, the gap between the semi-conductive layer that needs to be stripped and the main insulation layer Therefore, it is necessary to scrape off the semi-conductive layer including part of the main insulating layer by cutting during the construction of the cable head. During the stripping process, rough surface marks after cutting will be produced on the surface of the main insulating layer. According to the requirements of cable construction, the surface must be a smooth surface. Therefore, after the semicond...

AI Technical Summary

Problems solved by technology

There are some uncontrollable problems in this operation mode:

[0004] 1. The roundness requirements of the main insulation layer of the cable must be ensured when grinding the main insulation layer. Therefore, due to the operating habits or experience of each operator during grinding, the outer dimensions of the cable after grinding cannot be truly circular, which cannot meet the roundness requirements. degree requirements

[0005] 2. Since the operation process requires experience and visual inspection, it is difficult to accurately control the size of the cable grinding, which affects the safety of the cable head installation

[0006] 3. Due to the limitation of the work site and the two situations of horizontal operation and vertical operation during operation, the limited angle of cable grinding operation will increase the operating intensity of the operator

[0007] 4. A large amount of dust is generated when the insulating layer is polished, which affects the health of operators and pollutes the working environment
