Abstract

The invention discloses a bottom door opening and closing mechanism for a railway funnel vehicle. The bottom door opening and closing mechanism comprises a bottom door, a vehicle body underframe and a vehicle body side wall. The bottom door opening and closing mechanism further comprises a first end transmission device, a second end transmission device, a transmission shaft assembly, a central driving device, a bottom door opening device and a top door closing device. By operating an abutting pressure device on the ground, the bottom door opening device is opened to discharge goods; and the bottom door is closed by abutting against the top door closing device downwards. A locking function is achieved through the end transmission devices, the central driving device and a connecting pin shaft of the bottom door. According to the bottom door opening and closing mechanism, a complex wind-driven or manual control bottom door opening and closing system is omitted, and the loading weight of the vehicle is effectively improved.

Description

technical field [0001] The invention relates to an opening and closing mechanism for a bottom door of a railway funnel car, belonging to the technical field of railway funnel car parts. Background technique [0002] At present, there are two ways to control the opening and closing of the bottom door of railway hopper cars: pneumatic and manual control. Operators complete the unloading of goods through the pneumatic or manual control system installed at the end of the car body. On the one hand, this kind of pneumatic or manual control bottom door opening and closing mechanism is not highly automated, and the operating labor cost is high; on the other hand, the vehicle structure is complex, which increases the weight of the vehicle, thereby reducing the vehicle loading capacity. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an opening and closing mechanism for the bottom door of a railway hopper in view of the de...
