Locomotive rear end door

Abstract

The invention provides a locomotive rear end door. The locomotive rear end door comprises a door frame, a door skeleton, a sliding device and a lock; the sliding device comprises a cantilever frame, a pulley, a sliding fixing plate, a limiting block and a door stop block; the sliding fixing plate is arranged on the door frame, and a clamping groove matched with the pulley is formed in the sliding fixing plate; the cantilever frame is arranged on the door skeleton, the pulley is arranged on the cantilever frame, and the pulley is placed in the clamping groove of the sliding fixing plate; a limiting block for limiting sliding of the pulley and a door stop block are respectively arranged on the door frame and the cantilever frame; the lock comprises a lock body, a lock tongue, a spring, a pull rope and a door lock positioning block; a handle is arranged on the lock body, the handle is connected with the lock tongue through the pull rope, the lock tongue is provided with the spring, and the spring is used for resetting the spring bolt after the action of the lock tongue; and the lock tongue and the door lock positioning block are respectively arranged on the door skeleton and the door frame. According to the locomotive rear end door, opening and closing of the door is realized through the lock and back-and-forth sliding of the door is realized through the sliding device, so that the push-and-pull type vehicle door is formed, and the problem of insufficient locomotive space is well solved.

Description

technical field [0001] The invention relates to the technical field of locomotives, in particular to a rear end door of a locomotive. Background technique [0002] The rear door of the locomotive is an important component of the locomotive. It is installed on the rear wall of the machinery room and is an important passage connecting the two locomotives. The current rear door of the locomotive generally adopts a hinged structure, which is limited by the installation space. It is generally designed as an inward opening type, and a certain space needs to be avoided inside the locomotive to ensure the opening and closing space of the door, which often cannot meet the requirements of locomotives with insufficient space or small space; therefore, a new type of locomotive rear door is urgently needed in the industry. Contents of the invention [0003] The purpose of the present invention is to provide a locomotive rear end door to solve the problems in the background technology. ...
