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

Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict.

[0025] The arrow direction in the figure is the movement direction of the object to be measured.

[0026] Such as figure 2 with image 3 As shown, according to the embodiment of the present invention, the cable displacement measuring device includes a cable 52, a two-way guiding device for the cable, and a cable displacement sensor. The pull wire 52 extends from the pull wire displacement sensor and is wound around one side of the guide structure of the pull wire bidirectional guide device. The cable displacement sensor senses the change in the length of the cable 52 to measure the displacement of the moving object.

[0027] The pull-wire bidirectional guide device includes a fixed support ...

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 present invention specifically relates to the field of measuring devices, and in particular to a cable displacement measuring device. Background technique [0002] The commonly used pull-wire sensor is to fix the sensor itself in the moving direction of the measured object when testing. Such as figure 1 As shown, the wire-pull 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 movement direction of the measured object 20' is A to B. During the test, the movement distance of the measured object 20' is obtained by calculating the difference in the length of the extension of the cable end of the cable sensor 10'. figure 1 The test distance in is 10m. In order to ensure the accuracy of the test, a sensor with a range of 12-15m is generally selected. [0003] For long-distance measurement (≥10m), a large-range pull-wire sensor is often used. Large-range pull-wire ...
