Abstract
A startup stage protection device used in Electric Multiple Unit (EMU) train coupler experiment is provided between two test cars. The startup stage protection device is arranged between and tightly abuts two test cars at the starting stage of the experiment to receive a compressing force in place of the coupler. The startup stage protection device separates from the two test cars after the end of the starting stage.
Claims10
A startup stage protection device for an experiment of a coupler of Electric Multiple Unit (EMU) train, wherein the startup stage protection device is provided between two test cars used in the experiment, and the startup stage protection device is pressed between the two test cars during a startup stage of an experimental device to undergo a pressing force in place of the coupler, and the startup stage protection device is detached from the two test cars after the startup stage is completed,
- wherein the startup stage protection device comprises a support member, a first mounting base installed on one car and a second mounting base installed on another car, the first end of the support member is hinged to the second mounting base, and the second end of the support member is pressed against the one car or the first mounting base during the startup stage of the experimental device and detached from the first mounting base after the startup stage is completed,
- wherein the support member comprises a strut and a stopper connected to the strut and arranged below the strut, an end of the strut rests on an upper surface of the one car, and the stopper is pressured against an end surface of the one car.
