Measuring tool for turning radius of high-voltage cable

Abstract

The invention relates to a measuring tool for the turning radius of a high-voltage cable. The measuring tool is mainly characterized by comprising a horizontal straight ruler and an elastic rod, wherein a fixed end of the elastic rod and one end of the horizontal straight ruler are firmly arranged together; a movable end of the elastic rod is movably arranged in a slide way formed in the surface of the horizontal straight ruler; and when the movable end of the elastic rod is stressed by external force towards the fixed end, the elastic rod naturally forms a circular arc with varying radius. The invention provides a tool for directly measuring the turning radius of the high-voltage cable, wherein the horizontal straight ruler carved with the turning radius is connected with the elastic rod, external force is applied through the movable end of the elastic rod to drive the elastic rod to form the circular arc overlapped with the high-voltage cable, and the graduation at the junction of the horizontal straight ruler and the elastic rod is directly read to acquire the turning radius of the circular arc of the cable. The measuring tool has high measuring accuracy, is convenient to use and has a wide measuring range.

Description

technical field [0001] The invention belongs to the field of high-voltage cables, in particular to a tool for measuring the turning radius of high-voltage cables. Background technique [0002] During the laying process of high-voltage cables, national standards and relevant regulations should be strictly followed to ensure the normal function of high-voltage cables. According to national standards, during the laying process of high-voltage cables, their turning radius should not be less than 20 times their diameter D. At present, there is no tool for direct measurement of the turning radius of high-voltage cables. The usual measurement method is to measure the diameter of the cable in advance, and then use a steel plate to make an arc-shaped ruler of the corresponding diameter, and finally use the arc-shaped ruler on the construction site. Measurement, the measurement method is very inconvenient, and the measurement accuracy is low. Contents of the invention [0003] The...
