Quantitative range finder with protection structure and for rail transit fault diagnosis

Abstract

The invention relates to a quantitative range finder with a protection structure and for rail transit fault diagnosis. The quantitative range finder comprises a center device base and supporting legs,a top disc is installed at the top end of the middle of the center device base, the side end of the top disc is connected with an auxiliary fixing mechanism, a positioning hole is formed in the sidewall of the top tray, the side end of the center device base is connected with a physical measurement mechanism, and a storage opening is formed in the bottom end of the center device base. The quantitative range finder with the protection structure and for rail transit fault diagnosis can slidably adjust the use position of a column strip by sliding a column groove and the column strip, meanwhile, scale identification can be conveniently carried out by a user through the scale mark at the end part of the column strip, that is, when a rear object column and a front object column are movably regulated and controlled, the distance between the supporting legs at the two end parts of a device body can be speculated by referring to the length of the body and according to the scale mark, so thatthe user can physically measure the distance between the rails conveniently.

Description

technical field [0001] The invention relates to the technical field of distance measuring machines, in particular to a quantitative distance measuring machine with a protective structure for rail transit fault diagnosis. Background technique [0002] The range finder refers to a radio navigation device that measures the slant distance between the aircraft and the ground answering station. It is composed of an airborne interrogator and a ground answering station. The method of the distance between the two is generally applied to the distance measuring device on the track for distance detection. [0003] The existing ranging structure relies too much on electronic technology and intelligent performance, which is prone to failure. For example, the track is generally set in the wild, and its environment is special. When the body is damaged, it is impossible to maintain, repair and control, etc. It is very unfavorable that it cannot be carried out in time. At the same time, due ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a quantitative distance measuring machine with a protective structure for rail transit fault diagnosis, so as to solve the problem that the existing distance measuring structure proposed in the above background technology is too dependent on electronic technology and intelligent performance, and then it is easy to cause failure. The situation, such as the track is generally set in the wild, and its environment is special. When the body is damaged, maintenance, repair and regulation cannot be carried out in time, which is very unfavorable. At the same time, due to the unreasonable structural design of the body, the body It also cannot be equipped with a better protective structure, which greatly increases the failure rate of the main body
