Problems solved by technology

[0004] In the existing technology, the existing track gauge measurement structure requires two sensor signals, and the track gauge composite calculation increases the uncertainty of the measurement, and there is also the problem of synchronous triggering of the two sensor measurements. At the same time, the track gauge auxiliary measurement cannot be guaranteed The measurement point of the wheel is located at the true 16mm, which will further increase the measurement error

Embodiment Construction

[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0030] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

[0031] Unless otherwise def...

Abstract

The invention provides a track gauge measuring device and a track detector. The gauge measuring device comprises a cross beam, a measuring wheel set and an auxiliary measuring wheel set. A displacement sensor, a connecting guide rod and a connecting assembly are arranged in the cross beam; the connecting assembly comprises a connecting seat, a measuring guide rod and a screw measuring head; the auxiliary measuring wheel set is provided with a universal wave bead, and the screw measuring head abuts against the universal wave bead. According to the invention, the displacement sensor is adopted on the cross beam to detect the track gauge in real time, so that track gauge detection errors can be reduced to make the detection result more accurate, the structure can be simplified, and the weight can be reduced; secondly, the screw measuring head is arranged to abut against the universal wave bead for indirect measurement, so that the cross beam and the auxiliary measuring wheel set can be arranged in a split manner; since the measuring force is adjustable and does not influence the posture, the measuring force and the spring force for ensuring the posture are mutually independent; finally, the position between the auxiliary measuring wheel and the auxiliary walking wheel in the auxiliary measuring wheel set is relatively fixed, so that the measuring point is ensured to be positioned at the true 16mm position in real time.

Description

technical field [0001] The invention relates to the technical field of rail detection, in particular to a gauge measuring device and a rail inspection instrument. Background technique [0002] With the rapid development of science and technology and the improvement of people's living standards, high-speed rail, bullet trains and other travel methods have become one of the preferred tools for people to travel, so people are paying more and more attention to the safety performance of railway tracks. [0003] The existing T-type rail gauge measuring principle is: the product uses two sensors (gauge sensor + gauge auxiliary sensor) to measure the gauge change of the two rails respectively, and the measured value is obtained by combining and processing the two measurement signals through software. gauge value. [0004] In the existing technology, the existing track gauge measurement structure requires two sensor signals, and the track gauge composite calculation increases the un...
