Problems solved by technology

[0003] After the wheel sensor is installed, it is necessary to measure the distance from the center of the installation hole to the lower edge of the rail head and the top of the upper rail to ensure the installation height of the wheel sensor, and the degree of wear of the rail can be judged through measurement, so that the wheel sensor can be adjusted during maintenance. Sensitive installation position, at present, there is no suitable tool for accurate measurement of this

Abstract

The invention discloses a measuring gauge special for the assembly of a wheel sensor of an axis-counting system. The measuring gauge comprises a substrate, a measuring rod, a positioning rod and a measuring mark rod; the measuring rod and the positioning rod are fixedly installed on the substrate; the center lines of the measuring rod and the positioning rod are perpendicular; a positioning part matched with an installation hole to be measured is arranged on the positioning rod; the measuring mark rod is sleeved on the measuring rod; a measuring head for measuring a rail bottom and a measuring plane for measuring a rail top are arranged on the measuring mark rod; the distance between the installation hole and the rail bottom is measured by taking the center of the positioning rod as a lower reference and the measuring head as another reference; and the distance between the installation hole and the rail top is measured by taking the center of the positioning rod as the lower referenceand the measuring plane as another reference. The measuring gauge is simple in structure and convenient to use and can be used for accurately measuring the distance between the rail top and the installation hole of an axis-countering magnetic head device and the distance between the rail bottom and the installation hole of the axis-countering magnetic head device.

Description

technical field [0001] The invention discloses a multifunctional distance measuring device, in particular to a special measuring gauge for assembling wheel sensors of an axle counting system. Background technique [0002] Axle counting equipment is a safety application system that judges whether there is a train in the section by comparing the number of train axles detected by the wheel sensors installed at both ends of the train running section. If the judgment is wrong, accidents are likely to occur. The wheel sensor is one of the key equipment of the axle counting system, so the axle counting system requires very high installation accuracy of the wheel sensor. [0003] After the wheel sensor is installed, it is necessary to measure the distance from the center of the installation hole to the lower edge of the rail head and the top of the upper rail to ensure the installation height of the wheel sensor, and the degree of wear of the rail can be judged through measu...
