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

Abstract

The invention relates to a single-opening pressure rod type bottom door opening and closing mechanism and a hopper car. The fixed end of the driving part of the single-opening pressure rod type bottom door opening and closing mechanism is arranged on the car body, the output end of the driving part performs linear telescopic movement, the central axis of the driving shaft and the telescopic direction of the output end of the driving part are vertically arranged, The driving shaft and the output end of the driving member are connected by transmission; 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 to the first end of the first connecting rod; the bottom The door and the driving shaft are arranged oppositely, the distance between the bottom door and the driving shaft is less than the sum of the lengths of the first connecting rod and the second connecting rod, the top of the bottom door is rotatably connected to the vehicle body, and the bottom of the bottom door is connected to the second connecting rod. The second end of the rod is rotatably connected. The invention has the characteristics of simple structure, safety and reliability, high degree of automation and convenient operation, can quickly realize the opening and closing of the bottom door, can better adapt to some unloading sites with short unloading pits, and has good practicability.

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...
