Description

Locking device Technical Field The application belongs to the technical field of locomotive safety equipment, and particularly relates to a locking device. Background The coupler lifting rod locking device of some locomotives in the related art needs to be locked manually, so that the labor intensity of personnel is increased, and the risk of locking omission is easily caused by human negligence. The jump amplitude of the lifting rod is limited by the spring component so as to prevent the mistaken lifting of the hook. However, the locking device does not have an active locking function, and can only passively limit displacement, and the elastic component comprises more structural members, so that the whole device is complex in structure and high in maintenance cost. Disclosure of Invention It is an aim of embodiments of the present application to provide a locking device that solves at least one of the problems described above. In order to solve the technical problems, the application is realized as follows: The embodiment of the application provides a locking device, which comprises a fixed seat, a locking piece and a driving mechanism, wherein the fixed seat is provided with a locking groove; The locking piece is connected to the fixing base in a sliding manner along a first direction, and a locking part for locking the coupler lifting rod is arranged at one end of the locking piece along the first direction; the driving mechanism is connected with the locking piece and used for driving the locking piece to reciprocate in the first direction. In the embodiment of the application, the locking piece is driven to move along the first direction by the driving mechanism, so that the locking piece moves towards the coupler lifting rod, and finally, the locking of the coupler lifting rod is realized by contacting the locking part with the coupler lifting rod, thereby effectively preventing the coupler lifting rod from moving randomly. Compared with the prior art, the embodiment of the application adopts the driving mechanism as a power source to realize active locking, avoids locking in a manual mode, reduces the labor intensity of personnel, effectively relieves the risk of missed locking caused by human negligence, locks the coupler lifting rod instead of passively limiting displacement, and ensures the locking stability of the coupler lifting rod.
