Abstract

The invention relates to a bottom door opening-closing mechanism, a vehicle body and a hopper car. The bottom door opening-closing mechanism comprises an opening-closing lever, multiple connectors, two bottom door end plates, two hoisting bases, two operation levers, two lever round pins, two locking plates, two locking plate round pins and two bottom door locking pins. The vehicle body comprisestwo side wall assemblies, two end wall assemblies, a top cover assembly and a bottom frame assembly, and two bottom door opening-closing mechanisms. The two bottom door opening-closing mechanisms areinstalled at two sides of the vehicle body. The bottom door opening-closing mechanism can open or close a bottom door plate at one corresponding side in the bottom frame assembly. The bottom door opening-closing mechanism is capable of realizing the independent opening-closing control of the bottom door plates at the left and right sides of the vehicle body, simplifying an operating process, and improving discharging efficiency.

Description

technical field [0001] The invention relates to the technical field of railway transportation, in particular to a bottom door opening and closing mechanism, a car body and a hopper car. Background technique [0002] As a common type of railway transportation vehicle, the funnel car is widely used in the transportation of bulk goods such as minerals, grains, and chemical raw materials. , bogie composition. The car body is generally composed of side walls, end walls, underframes, top covers and bottom doors. Among them, the bottom door consists of middle beams, beams, end plates and bottom door panels. The bottom door panels pass through the bottom door opening and closing mechanism The drive completes the opening and closing actions. Among them, the bottom door panels on both sides of the car body are sealed by lap joints. The opening and closing of the bottom door panels have sequential requirements. When the bottom door is opened to unload, only the left bottom door panel ...
