Abstract

The invention relates to a method for measuring a railway vehicle brake pipe assembly. The measuring method firstly determines the standard horizontal position and the standard height position of pipe joints at the both ends of the designed brake pipe assembly according to the shape of the designed brake pipe assembly, thereby obtaining the standard mobile measuring position and the standard fixed measuring position; then a fixed measuring head and a mobile measuring head are respectively fixed at the standard fixed measuring position and the standard mobile measuring position; the fixed measuring head is used for measuring the pipe joint at one end of the measured brake pipe assembly; the pipe joint is fixed on the fixed measuring head; the mobile measuring head is used for measuring thepipe joint at the other end of the measured brake pipe; if the axial dimension of the measured brake pipe assembly is also inosculated with the set value, the measured brake pipe assembly is qualified. The method solves the technical problems of complicated operation, difficult positioning, lower measurement efficiency and lower measurement precision in the background technology. The method can meet the measurement requirements of the brake pipe assemblies in various shapes, and the one-time positioning can meet the measurement requirements of all the parts of the brake pipe assembly.

Description

technical field [0001] The invention relates to a brake pipe measuring device, in particular to a method for measuring the composition of a railway vehicle brake pipe. Background technique [0002] The brake pipe is a part of the railway freight car, which is composed of the brake pipe and the joint body after welding, and has various shapes such as S-shape, L-shape, U-shape and three-dimensional space pipe. The detection of the composition of the brake pipe is generally carried out by manual measurement with common measuring tools such as platforms, squares, steel rulers, and tape measures. At present, no matter it is a railway wagon factory or a maintenance factory, there is no special detection device composed of brake pipes. The main disadvantages of using general measuring tools to measure the composition of brake pipes are as follows: [0003] The measurement of the brake pipe composition first requires positioning. Due to the complex shape of the brake pipe composit...
