Abstract

The invention provides a steel rail pressure test platform which can be used for simulating a steel rail pressure or tension test. The steel rail pressure test platform comprises an intelligent pressure gauge, a pressure tool and a steel rail installation test bench, wherein the pressure tool can simulate a train wheel pair and steel rail contact surface; the steel rail installation test bench includes a support seat, a support member, a mounting plate, a positioning plate, a sleeper, a steel rail, a steel rail fastener and a fastener; the mounting plate needs to be installed with the intelligent pressure gauge; the support member can be adjusted in height; the sleeper is mounted on the mounting plate in cooperation with the positioning plate; and the steel rail is installed on the sleeperin cooperation with the steel rail fastener. In the steel rail pressure test platform, the steel rail is installed on the test bench, and pressure is applied to the steel rail through the intelligentpressure gauge and the pressure tool. A test result can be collected by the intelligent pressure gauge and a test device installed on the steel rail, and reliable test data can be obtained.

Description

technical field [0001] The invention relates to the technical field of rails, in particular to a rail pressure test platform. Background technique [0002] Rail transit is an important form of transportation, including urban light rail transit, subway, high-speed railway, heavy-duty railway, etc. With the rapid development of my country's rail transit, the transportation capacity and volume continue to increase, and the damage of rails is also increasing. Rail head peeling, corrugation, and side grinding are some of the most typical forms of rail damage. [0003] At present, there are two types of rail damage detection methods, one is manual detection, through the inspection along the track by workers in the railway construction section, and the degree of rail damage is checked by naked eyes and special measuring devices. This method is inefficient and prone to missed detection and false detection. Another method is to use rail inspection cars, but the rail inspection car...
