Bottom door mechanism and locking device of railway freight car

Abstract

The invention discloses a locking device for a bottom door mechanism of a railway freight car. The bottom door mechanism includes a rotating arm and a bumper; the locking device includes a vertical push rod slidingly connected with the rotating arm, and a The rotating part that is rotatably connected to the arm, the axis of the rotating part is parallel to the rotating shaft of the rotating arm, the driving part that drives the rotating part is connected between the rotating part and the push rod, and also includes a fixed position There is a channel on the rotating arm or the rotating part; when the push rod is not pushed up by the meeting head and the rotating arm rotates in the direction of opening the door, the driving part drives the rotating part to a position where the limiting part cannot The position of the access passage; when the bottom door is normally closed and opened normally, the driving member drives the rotating member to rotate to a position where the limiting member can pass through the passage. The locking device can realize automatic locking, prevent leakage of goods, and cancel human operation. The invention also discloses a bottom door mechanism of a railway wagon using the locking device.

Description

technical field [0001] The invention relates to the technical field of railway freight cars, in particular to a bottom door mechanism of a railway freight car and a locking device thereof. Background technique [0002] Railway wagons are mainly used to transport steel, timber, construction materials and bulk goods (including coal, coke and ore, etc.). For example, a funnel car is a kind of railway wagon whose end wall is inclined inward or whose end surface is a large arc, and the lower part of the car body is equipped with a funnel. The goods are loaded from the top, and the bottom door of the funnel is opened when unloading, and the goods are automatically unloaded by self-gravity. It is mainly used for loading ore, cement, coal and other bulk goods, which is of great significance in railway transportation. [0003] The bottom door mechanism of a railway freight car usually includes a rotating arm and a bumper. The bumper lifts up the rotating arm, and drives the rotating...

Problems solved by technology

[0005] Using the above method, since the operator needs to manually place or remove the stopper, it wastes a lot of manpower, and there are also potential safety hazards. If the vehicle is unloaded and the locking stopper is forgotten, it may cause vehicle damage or even derailment.
