Single-open pressing rod type bottom door opening and closing mechanism and hopper car

Abstract

The invention relates to a single-open pressing rod type bottom door opening and closing mechanism and a hopper car. A fixed end of a driving part of the single-open pressing rod type bottom door opening and closing mechanism is arranged on a vehicle body, an output end of the driving part is designed to perform linear telescopic motion, a central shaft of a driving shaft is perpendicular to the telescopic direction of an output end of the driving part, and the driving shaft is in transmission connection with the output end of the driving part; the first end of the first connecting rod is rotatably connected to the driving shaft, and the first end of the second connecting rod is rotatably connected with the first end of the first connecting rod; a bottom door and the driving shaft are oppositely arranged, the distance between the bottom door and the driving shaft is smaller than the sum of the lengths of the first connecting rod and the second connecting rod, the top of the bottom dooris rotationally connected with the vehicle body, and the bottom of the bottom door is rotationally connected with the second end of the second connecting rod. The single-open pressing rod type bottomdoor opening and closing mechanism has the characteristics of being simple in structure, safe, reliable, high in automation degree and convenient to operate, opening and closing of the bottom door can be rapidly achieved, the single-open pressing rod type bottom door opening and closing mechanism can better adapt to some unloading sites with short unloading pits, and good practicability is achieved.

Description

technical field [0001] The invention belongs to the technical field of railway wagons, and in particular relates to a single-opening lever type bottom door opening and closing mechanism and a hopper car. Background technique [0002] The hopper car with a bottom door is mainly used to transport bulk goods on railway lines. After the vehicle arrives at the destination, the bulk goods are unloaded onto the conveyor belt or in the bottom pit by unloading at the bottom. [0003] In the prior art, the unloading door (called the bottom door) at the bottom of the hopper car is generally opened and closed by an opening and closing mechanism, and the operation of the opening and closing mechanism is manual operation, which is labor-intensive and low in unloading efficiency. In some unloading pits, it is relatively short. The unloading site is not suitable. Contents of the invention [0004] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides...
