Hopper car bottom door with locking device and hopper car

Abstract

The invention discloses a hopper car bottom door with a locking device and a hopper car, and relates to the field of railway wagons. The hopper car bottom door comprises: a door frame, wherein a sliding rail assembly is arranged on one side of the door frame, a door plate is movably arranged in the door frame, and the door plate can move towards the outside of the door frame along the sliding rail assembly; an operation shaft, wherein the operation shaft is arranged in the sliding rail assembly in a penetrating mode, the operation shaft is sleeved with a gear, and the door plate is meshed with the gear through a rack; and a locking device, wherein the locking device is movably arranged on the sliding rail assembly, the locking device comprises a clamping jaw, and the clamping jaw is matched with the end, away from the door plate, of the rack. Modularized installation of the hopper car bottom door is achieved, the structure is simple, operation is convenient, the operation shaft is rotated to drive the gear and the rack, so that the bottom door can move in the door frame; and the locking device is additionally arranged, and production accidents caused by automatic opening of the bottom door are avoided through meshing limiting of the clamping jaw and the rack.

Description

technical field [0001] The invention belongs to the field of railway wagons, and more specifically relates to a bottom door of a hopper car with a locking device and a hopper car. Background technique [0002] Generally, the structure of the bottom door and the opening and closing mechanism of the hopper car is relatively complicated, and modular assembly cannot be realized. When some structures are heavy-loaded, there is no drag-reducing mechanism during the opening and closing process of the bottom door, manual opening and closing is laborious, and there is no locking device. Contents of the invention [0003] The object of the present invention is to address the deficiencies in the prior art, to provide a hopper car bottom door with a locking device and a hopper car, to realize modular installation of the hopper car bottom door, simple in structure and easy to operate, by rotating the operating shaft Drive the gear and rack to move the bottom door in the door frame, and...
