Problems solved by technology

According to the standard requirements of the Glen head, it is necessary to use an M40 torque wrench for tightening during installation, and then apply a torque of 22N.m for tightening. During disassembly, maintenance and replacement, common installation tools cannot be used to apply tightening torque. The Glen head can only be tightened by hand
Long-term use, under vibration and other conditions, it is easy to loosen, and the effect of fastening the cable and waterproofing cannot be achieved

Abstract

The invention particularly relates to a tool used for screwing of screwing parts of narrow space, and belongs to the technical field of cable waterproof joint mounting tools. The technical aim to be achieved is to provide a tool used for screwing of screwing parts of narrow space. According to the adopted scheme, a semicircular arc structure is adopted by a clamping portion, the clamping portion is vertically arranged in the axial direction, and the side, facing the axis, of the clamping portion is a semi-hexagonal safe; a semicircular conic structure is adopted by an extending connecting portion, the extending connecting portion is arranged obliquely oppositely to the vertical face in the axial direction, and the lower end of the extending connecting portion and the upper end face of theclamping portion are fixed; a screwing seat is fixed to the upper end of the extending connecting portion, a screwing connecting hole vertical in the axial direction is arranged on the screwing seat,and the screwing connecting hole is used for being in clamped connection with the end of a torque wrench. The tool completes fastening mounting of cable glands of narrow space, is good in mounting andfastening effect and achieves the waterproof effect.

Description

technical field [0001] The invention belongs to the technical field of installation tools for cable waterproof joints, and in particular relates to a tool for tightening tightening parts in narrow spaces. Background technique [0002] Glen head, also known as cable waterproof joint, cable fixing head, as the name implies, is used to fasten the cable and waterproof. When installing and using the standard Glen head, you only need to choose the appropriate model according to the size of the cable, and according to the tightening torque Standard, using a commonly used torque wrench to install and tighten can achieve the connection and waterproof effect. The 17 cables connected externally to the transformer & reactor cabinet are connected to the cabinet and the locomotive through a 1450×128×426 junction box. One end of the external cable is connected to the main control box of the cabinet, and the other end is connected to the main line of the locomotive. For connecting fastenin...
