The secondary locking device of the bottom door of the hopper car and the hopper car

Abstract

The invention relates to a secondary locking device for the bottom door of a funnel car and a funnel car, which are used for the secondary locking of the bottom door of a railway funnel car; the railway funnel car includes a bottom door and a primary locking device; the secondary locking device includes: a hook part, the hook part is pivotally installed on the vehicle body outside the bottom door, and can pivot along the vehicle body, the first side of the hook part includes a guide part and a lock part, and the lock part The part is suitable for forming a locking fit with the bottom door of the hopper car to apply an upward lifting force to the bottom door, and the guide part is suitable for guiding the hook part and the bottom of the hopper car from a disengaged state to a locked state; One end of the spring unit is connected to the second side of the hook member, the second side and the first side are respectively located on both sides of the pivot, and the other end of the spring unit is connected to the vehicle body outside the bottom door Other parts are connected for applying force to the hook member. The secondary locking is realized through the above method, which improves the safety of the hopper car.

Description

technical field [0001] The invention relates to a secondary locking device for a bottom door of a hopper car and a hopper car, belonging to the technical field of railway vehicles. Background technique [0002] The bottom door opening and closing mechanism of the railway bottom door hopper car for loading ore, coal and other goods usually adopts a mechanical linkage transmission mechanism. When the vehicle is in operation, the bottom door is located at the bottom of the compartment to bear the weight of the cargo. If the bottom door of the vehicle is opened during operation, the goods will be dumped on the line, causing major safety accidents such as derailment or tipping of the vehicle. Therefore, in order to ensure the safe operation of the vehicle, the bottom door must be provided with a reliable self-locking method or device to ensure that the bottom door is locked and will not automatically open during the operation of the vehicle. [0003] At present, the bottom door...

Problems solved by technology

The realization of this scheme is based on the transformation of the ground facilities. The structure of the ground facilities is relatively complicated, which is not conducive to the user's use and maintenance; at the same time, the vehicle will inevitably swing from side to side when running on the track, and the contact wheels used in the above application either cannot be compatible with Contact with the inclined surface of the door, or the compression amount is too large, and the lock pin is bent. In both cases, the "secondary locking function" cannot be effectively realized.
