Problems solved by technology
[0003] Because the height of the obstacle remover of the rail vehicle body is relatively low and it is close to the track surface, there is a great difficulty in loading. At the same time, it needs to be loaded with other large-scale test equipment, which has a large workload, high labor intensity, and low efficiency. More auxiliary personnel are required, which is not conducive to reducing the cost of the test

The invention relates to the field of testing of vehicle body cowcatchers, in particular to a static strength test device for a rail vehicle body cowcatcher. The test device comprises: a vehicle bodystrength test bench, a support structure, a force applying structure and a force sensing structure, wherein the vehicle body strength test bench comprises a fixed longitudinal beam and a moving transverse beam, the moving transverse beam is fixedly mounted on the fixed longitudinal beam, the extension axis of the moving transverse beam faces the direction of the vehicle body of the rail; the firstside of the upper portion of the bracket structure abuts the moving transverse beam, the lower portion of the bracket structure abuts the fixed end of the force applying structure, the force applyingend of the force applying structure abuts the first end of the force sensing structure, and the second end of the force sensing structure is used to abut the cowcatcher. The static strength test device can quickly realize the loading of the cowcatcher and greatly reduce the required auxiliary parts, and is high in efficiency and small in the number of auxiliary personnel required, which can significantly shorten the test period of the cowcatcher.
Description
technical field [0001] The invention relates to the field of testing a vehicle body obstacle remover, in particular to a static strength test device for a rail vehicle body obstacle remover. Background technique [0002] The train runs at a high speed and has high safety requirements. During the high-speed operation of the train, any obstacle on the track can damage the train, or even cause the train to derail, causing a safety accident. Therefore, the front car of the train needs to be equipped with a device for removing obstacles, that is, a troubleshooter. In order to ensure the elimination of obstacles, the train usually installs troubleshooting devices in different positions, such as installing on the car body, mainly used to remove large foreign objects on the track, so the car body troubleshooting device is also called the main troubleshooting device; It is used to remove small ballast (gravel) and other foreign objects on the track, and it serves as an auxiliary obs...
