Stay wire displacement measurement device

Abstract

The invention provides a stay wire displacement measurement device, which comprises a stay wire (52) and a stay wire double-way guiding device, wherein the stay wire double-way guiding device comprises a first guiding mechanism (20) and a second guiding mechanism (30) which are fixedly arranged, the arc guide surface of the first guiding mechanism (20) is opposite to the arc guide surface of the second guiding mechanism (30), and a mounting space (40) is formed between the arc guide surface of the first guiding mechanism (20) and the arc guide surface of the second guiding mechanism (30), and the stay wire (52) passes through the mounting space (40) and is arranged on the first guiding mechanism (20) or the second guiding mechanism (30). According to the stay wire double-way guiding device of the stay wire displacement measurement device, the measurement range of the stay wire displacement measurement device is expanded, and the advantages of reduction in the length of the stay wire, simple structure, convenience for use and effective reduction in cost are achieved.

Description

technical field [0001] The invention specifically relates to the field of measuring devices, in particular to a wire displacement measuring device. Background technique [0002] Commonly used pull-wire sensors are tested by fixing the sensor itself in the moving direction of the measured object. Such as figure 1 As shown, the pull wire sensor 10' is fixedly arranged along the moving direction of the object, and the wire end is fixedly connected to the measured object 20', and the moving direction of the measured object 20' is from A to B. During the test, the moving distance of the measured object 20' is obtained by calculating the difference in length of the stretched wire end of the wire sensor 10'. figure 1 The test distance in the test is 10m. In order to ensure the accuracy of the test, a sensor with a range of 12-15m is generally selected. [0003] When performing long-distance measurement (≥10m), it is often necessary to use a large-range pull-wire sensor. Large-r...

AI Technical Summary

Problems solved by technology

Large-range pull-wire sensors (≥10m) generally need to be customized, and are large in size, poor in portability, and high in cost

Taking the domestic pull wire sensor as an example, the price of a 10m pull wire displacement sensor is generally more than 5,000 yuan, while the imported sensor is as high as tens of thousands of yuan, which limits the application of this test method to a certain extent
