Traction pin loading device for strength test of car body

Abstract

The invention relates to a traction pin loading device for a strength test of a car body. The traction pin loading device includes a base, a support base, a loading mechanism and a control unit, wherein the base is fixed on the ground, the support base is fixed on the base, and the tested car body is placed on the support base; the loading mechanism includes a transverse loading mechanism body, a longitudinal loading mechanism body and a perpendicular loading mechanism body, wherein the transverse loading mechanism body, the longitudinal loading mechanism body and the perpendicular loading mechanism body exert load on a traction pin in the transverse direction, in the longitudinal direction and in the perpendicular direction respectively and are connected with the control unit. The traction pin loading device is simple in overall structure and capable of performing a loading test on the traction pin in the three directions, satisfying the requirements of the traction pin strength test of a motor train unit and a metro and guaranteeing the accuracy and reliability of test data. In this way, the performance of the car body can be known better, and a better guarantee is supplied to the quality improvement of a vehicle.

Description

technical field [0001] The invention relates to a strength test device for a rail vehicle body, in particular to a traction pin loading device for a vehicle body strength test capable of carrying out lateral, longitudinal and vertical loading tests on a traction pin of a tested vehicle body. Background technique [0002] With the rapid development of domestic rail transit, high-speed EMUs and urban rail vehicles have been widely used. In order to meet the needs of the development of rail transit, it is necessary to better understand the various performances of the vehicles and to ensure the quality of the vehicles provided, it is necessary to conduct a strength test closer to the actual body; the existing EMU and subway test body Due to the limitation of the test site, the traction pin test device can only change the test tooling after the loading test in one direction is completed, and then do the next loading test; this requires more test tools and a large amount of labor....

Problems solved by technology

In order to meet the needs of the development of rail transit, it is necessary to better understand the various performances of the vehicles and to ensure the quality of the vehicles provided, it is necessary to conduct a strength test closer to the actual body; the existing EMU and subway test body Due to the limitation of the test site, the traction pin test device can only change the test tooling after the loading test in one direction is completed, and then do the next loading test; this requires more test tools and a large amount of labor. Seriously affect the test period, and the traction pin test cannot be completed quickly; therefore, in view of the above problems, a new traction pin loading device is specially developed, and the loading test in three directions can be completed on the loading device. The test loading device is easy to install , the traction pin loading device can greatly reduce the workload and labor intensity of the test and shorten the test preparation test. It has high safety and is of great significance to improving the efficiency and quality of the test.
