Abstract

The invention belongs to the technical field of rail vehicle couplers, and in particular relates to a coupler and a locking method thereof. The coupler includes a gib head, on which a sliding part is arranged; a fixing device, installed on the end wall of the car body, with a guide rail formed on one side edge, and a locking block is arranged on the fixing device; the hook The head is also provided with a locking device, driven by an external force, the slider on the hook head moves along the guide rail to the direction of the locking block until the locking device cooperates with the locking block, To realize the locking of the coupler, the folding locking, unlocking, or straightening locking process of the present invention can be completed with one hand without too much manual intervention, the action track is clear and clear, and the operation is convenient, efficient and automatic.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle couplers, and in particular relates to a coupler and a locking method thereof. Background technique [0002] The coupler is located at both ends of the rail vehicle and plays the role of transmitting the longitudinal force between the vehicles. In some types of rail vehicles (such as low-floor trams or high-speed EMU trains), the couplers at both ends of the train are not exposed during operation, but are hidden behind the opening and closing mechanism or the shroud at the end of the train, and are only used in rescue It is used to make the appearance of the train more beautiful and coordinated, and to effectively reduce the air resistance when running at high speed. [0003] In this application, "vehicle" refers to a single car; "train" refers to a multi-car formed by connecting and marshalling two or more cars. [0004] In order to save space and achieve the effect of hiding when not in u...
