Problems solved by technology

[0003] However, at present, in construction, a spirit level plus a ruler or a tape measure is used to measure, or even a visual method to judge the bending amount of the crimped tube after compression. There is no special tool for measuring the bending degree of the crimped tube, so the crimping of the crimped tube Process is difficult to control

Abstract

The invention, which belongs to the technical field of crimping process control and detection of the power transmission line crimping pipe, relates to a special-purpose tool for measuring the curvature of a power transmission line crimping pipe. The tool comprises a measuring bracket, a bending amount measuring device and a crimping pipe post-crimping length measuring device. The measuring bracketincludes a first supporting part, a first fixed base and a cross beam. The bending amount measuring device includes a telescopic measuring rod, a measuring rod sliding block and a measuring roller. The crimping pipe post-crimping length measuring device includes a first sliding block, a second supporting part and a second fixing base. With the tool, the bending amount of the crimping pipe and thelength of the crimped crimping pipe can be measured at the same time to obtain a bending deformation value. The tool is light can be applied to ground crimping construction control and high-altitudemeasurement; after fixation of a fixing device in the high-altitude measurement, the high-altitude operation personnel can carry out operation conveniently, so that the problem of difficult high-altitude operation is solved. The tool is easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of crimping process control and detection of crimping tubes of power transmission lines, and in particular relates to a special tool for measuring the bending degree of crimping tubes of power transmission lines. Background technique [0002] The joints of the transmission line conductors and ground wires are all connected hydraulically with crimping tubes. During the crimping process, if the die used in the hydraulic pressure does not match the crimping tubes, or the grounding wires and the crimping tubes are not kept horizontal during crimping, If it is not consistent with the axis of the hydraulic press, it will cause the crimping tube to bend after being pressed. In general, the narrower the width of the die, the more the modulus of the crimp, and the greater the curvature. The visible deformation within the range of bending deformation less than 2% should be straightened, and the deformation is equal to...
