Side-hung type lower side door for railway open wagon

Abstract

The invention discloses a side-hung type lower side door for a railway open wagon. The lower side door comprises a door frame, a door plate, a primary locking mechanism and a secondary locking mechanism, wherein the door frame is arranged on the side wall of a carriage of the railway open wagon, the door plate is hinged to the door frame through a hinge, the hinge is arranged on one side, close to the wagon head or the wagon tail of the railway open wagon, of the door plate, and a lock seat is arranged on the door frame; and a locking hole is formed in the lock seat, the primary locking mechanism is arranged on the door plate, and a lock arm of the primary locking mechanism is matched with the locking hole in an inserted mode. The lower side door is hinged to the door plate through the door frame to form the side-hung type lower side door, and the locking function of the lower side door is quite reliable through the primary locking mechanism and the secondary locking mechanism; and comprehensively compared with an existing lower side door, the lower side door has high practicability and economical efficiency for improving the unloading speed of the open wagon, reducing the transportation cost and reducing the transportation workload and the risk coefficient.

Description

technical field [0001] The invention belongs to the technical field of railway wagon car bodies, and more specifically relates to a flat-opening lower side door for a railway gondola. Background technique [0002] The gondola car is mainly used to transport bulk goods such as coal, ore, mining construction materials, timber, and steel, and can also be used to transport light-weight machinery and equipment. In my country's existing railway wagon composition, it accounts for more than 50% of the total number of wagons. The side door and the lower side door are the most frequently used body parts of the gondola car during manual or mechanical loading and unloading operations. The safety, corrosion resistance, and sealing of the door locks all affect the operation safety and operation and maintenance costs of the gondola car. [0003] The lower side door of the existing gondola car is opened upwards. When it is turned up, it needs to be connected to the hook set at a relatively...

AI Technical Summary

Problems solved by technology

[0003] The lower side door of the existing gondola car is opened upwards. When it is turned up, it needs to be connected to the hook set at a relatively high position on the side wall. The connection is difficult, and the operation is labor-intensive, posing a safety hazard. The closing function fails, and the door locks open during the operation of the vehicle, endangering transportation safety
