Rail transit vehicle life guard static strength test method and device

Abstract

The present invention discloses a rail transit vehicle life guard static strength test method. The method comprises the steps of: performing forward projection of a surface to be tested of a life guard along a horizontal direction, and employing a forming method to determine an outer contour of a loading area of the life guard; manufacturing a casting mould according to the outer contour of the loading area; allowing the casting mould to be in tightly contact with the surface to be tested of the life guard, keeping the casting mould and the surface to be tested of the life guard to be relatively fixed, performing workpiece casting in the casting mould, and forming a load loading head; installing the load loading head onto the life guard, and allowing a loading surface of the load loading head to be in tightly contact with the surface to be tested of the life guard; and performing load loading of the load loading head along the horizontal direction by employing a loading test system. Onthe basis of smoothly completing a static strength test, the rail transit vehicle life guard static strength test method can avoid relative slipping between a loader and a life guard in the test process, and can improve a structural strength of the load loading head and the uniformity of load loading. The present invention further discloses a rail transit vehicle life guard static strength test device. The device has advantages mentioned above.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicles, in particular to a method for testing the static strength of a rail transit vehicle obstacle remover. The invention also relates to a static strength test device for a rail transit vehicle obstacle remover. Background technique [0002] With the development of China's machinery industry, more and more machinery and equipment have been widely used. [0003] In the locomotive industry, rail transit vehicles have also derived many varieties, such as trains, subways, light rails, and maglev trains. Rail transit vehicles must run along the paved track, so it is very important that the track surface is clean and unobstructed. [0004] In order to ensure the safety of the track surface, obstacle removers are often installed on rail transit vehicles. The rail vehicle obstacle remover is an important device for removing possible obstacles in the track area. It not only undertakes the func...
