Description

Technical Field

[0001] The present invention relates to the technical field of locomotive coupler experiments, and in particular to a locomotive coupler reconnection track moving mechanism and a reconnection test method. Background Art

[0002] Locomotives need to undergo a coupler reconnection test before leaving the factory. Currently, there are many types of coupler structures, and the connection heights are also different. For example, the close-jointed couplers for high-speed trains and EMUs are different from traditional coupler connections. They must be replaced with universal process couplers during towing or reconnection tests. Close-jointed couplers and process couplers need to be frequently replaced and used under different working conditions in the factory, and the replacement of couplers must be done at designated workstations with trenches. The site is greatly restricted and the guide vehicle trailer needs to be moved back and forth, which is time-consuming and labor-intensive, greatly reducing the production efficiency of the locomotive.

[0003] Two locomotives can be reconnected normally using a close-fitting coupler, but often there is only one newly developed and manufactured locomotive and there is no close-fitting coupler connected to it, so the coupler reconnection test cannot be carried out in the factory.

[0004] The height of the process couplers installed on high-speed trains and EMUs is often different from the height of the common couplers on trailers. A transition structure needs to be installed to connect the two couplers with a height difference. However, this transition structure is prone to loosening and being unstable after installation. It often becomes loose and falls off during towing back and forth, operation, curve turning, and hook installation, affecting normal vehicle guiding operations or test applications.
