Loading device for static strength test of car body end wall

Abstract

The loading device for the static strength test of the car body end wall belongs to the field of force loading devices for the static strength test of the rail passenger car end wall, and includes a loading beam, two door-shaped beam hangers, two flange clamps and two force cylinders , the front end of each door-shaped beam hanger is fixedly connected with a corresponding flange card seat, and the front end of each door-shaped beam hanger is fixedly connected with a corresponding force cylinder; each door-shaped beam The hanging seat, the flanging card seat and the force cylinder together constitute a positioning loading device; each positioning loading device is fixedly connected to one end of the loading beam through its door-shaped beam hanging seat, and the two positioning loading devices are connected to one end of the loading beam. The vertical planes of the long sides are mirror-symmetrically arranged. In the present invention, the sling is connected with the hoisting sling, and the loading device for the static strength test of the car body end wall can be transferred to a suitable test height, and the force cylinders fixedly connected to the rear of each flange holder can be used to apply force to the end wall. Force, so that the static strength compression test of the car body end wall 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
