Embodiment Construction

[0054] The core of the present invention is to provide a rail collision trolley, and the test universality of the rail collision trolley is improved.

[0055] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0056] Please refer to Figure 1 to Figure 23 .

[0057] refer to figure 1 with figure 2 In a specific embodiment, the track collision trolley provided by the specific embodiment of the present invention includes a saddle frame 1, a center of mass adjustment unit 2 and a running unit 3, and the center of mass adjustment unit 2 and the running unit 3 are installed on the saddle frame 1 Above, the centroid adjustment unit 2 is used to adjust the vertical centroid height of the rail collision trolley. Specifically, the two groups of running units 3 are symmetrically and fixedly i...

Abstract

The invention discloses a rail collision trolley which comprises a saddle-shaped frame, a centroid adjusting unit and a walking unit. The centroid adjusting unit and the walking unit are installed onthe saddle-shaped frame, and the centroid adjusting unit is used for adjusting the vertical centroid height of the rail collision trolley. According to the rail collision trolley, the trolley frame isthe saddle-shaped trolley frame, so that the mass center height of the rail collision trolley in the no-load state is reduced; meanwhile, the mass center adjusting unit is arranged to achieve the mass center height adjustment, then the function of simulating different vehicles is achieved, and therefore the test universality of the rail collision trolley is improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle collision tests, in particular to a rail collision trolley. Background technique [0002] In the field of rail vehicle crash tests, due to the high cost and certain risk of using real vehicle crash tests, rail crash rigs are the most direct and effective method to study rail vehicle crashes. The main method is to install the tested parts such as coupler buffer device, anti-climbing device, crush pipe, structural energy-absorbing area, end energy-absorbing system, etc. on the rail collision trolley, and use the rail collision trolley instead of the real vehicle for the test. To study the crash performance of components, because the track crash trolley can be used repeatedly and the processing is simple, the test cost and risk are greatly reduced. [0003] However, since the traditional rail collision trolley is only for a certain type or a specific type of vehicle, separate corresponding rail...
