Loading device for static strength test of end wall of car body

Abstract

The invention provides a loading device for a static strength test of the end wall of a car body, belonging to the field of active force loading devices for static strength tests of the end walls of railway vehicles. The loading device of the invention comprises a loading crossbeam, two crossbeam hanging seats with shapes resembling the upper-case letter of Pi, two flanged clamping seats and two force applying cylinders, wherein the front end of each crossbeam hanging seat is fixedly connected with one corresponding flanged clamping seat and with one corresponding force applying cylinder; eachcrossbeam hanging seat, the corresponding flanged clamping seat and the corresponding force applying cylinder compose one positioning and loading unit; each positioning and loading unit is fixedly connected with one end of the loading crossbeam via the corresponding crossbeam hanging seat; and two positioning and loading units are arranged in mirror symmetry about the mid vertical plane of the long edge of the loading crossbeam. According to the invention, a lifting rope is connected with a lifting sling so as to lift the loading device to an appropriate test height; and the force applying cylinders respectively in fixed connection with the rear parts of the flanged clamping seats are utilized for applying force to the end wall, so the static strength compression test of the end wall of the car body can be implemented.

Description

technical field [0001] The invention belongs to the field of a force loading device for a static strength test of a rail passenger car end wall, and in particular relates to a loading device for a static strength test of a car body end wall. Background technique [0002] Such as figure 1 and figure 2 As shown, the end wall 1 of the rail passenger car is mainly the wall body of the door structure formed by the combination of the end wall vertical plate 1-1 and the side wall outer edge rib 1-2, and the side wall outer edge rib 1-2 is perpendicular to the end wall The plane where the wall vertical plate 1-1 is located is formed by welding it. Due to the needs of the welding process, and in order to strengthen the mechanical structural strength of the side wall outer edge rib 1-2, the edge of the side wall outer edge rib 1-2 is also provided with an inside turn parallel to the end wall vertical plate 1-1. Side 1-2-1. [0003] The static strength test of the car body structu...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the edge of the outer edge rib of the existing side wall is provided with an inner flange parallel to the vertical plate of the end wall, the existing force-loading hydraulic cylinder for the static strength test of the car body structure cannot match the inner flange, resulting in its The force of the compression test cannot be loaded on the outer edge rib of the side wall, thereby causing the technical problem that the static strength test of the end wall of the car body cannot be implemented. The invention provides a loading device for the static strength test of the end wall of the car body
