Bottom door opening device of railway wagon

Abstract

The invention discloses a bottom door opening device of a railway wagon. The bottom door opening device comprises an upper crank throw and a lower crank throw, the ends, close to each other, of the upper crank throw and the lower crank throw are in key connection to a transmission shaft, an included angle is formed between the upper crank throw and the lower crank throw, and a power structure, a first connecting rod and a second connecting rod are arranged at the end, away from the transmission shaft, of the upper crank throw; a round pin is arranged at the ends, close to each other, of the first connecting rod and the second connecting rod in a penetrating mode, the ends, away from each other, of the first connecting rod and the second connecting rod are hinged to the two bottom doors correspondingly, and the two ends of a transmission rod are rotationally connected with the round pin and the end, away from the transmission shaft, of the lower crank throw correspondingly. According to the bottom door opening device of the railway wagon, goods can be unloaded to the inner side of a track, the structure is simple, the operation is convenient, the bottom doors are locked through dead points of the first connecting rod and the second connecting rod after being closed, and the automatic opening of the bottom doors is avoided.

Description

technical field [0001] The invention belongs to the technical field of opening a door from the bottom of a railway freight car, and more particularly relates to a device for opening a door from the bottom of a railway freight car. Background technique [0002] Bulk goods transported by railway wagons are generally unloaded by opening the door at the bottom. According to the different receiving facilities on the ground, it can be divided into two types: unloading on the inside of the track and unloading on the outside of the track. Domestic trucks mostly use the outside of the track to unload. The opening and closing mechanism of the bottom door of the truck unloading on the inner side of the track is generally equipped with a transmission shaft, which is connected to the bottom doors on both sides through double bell cranks and connecting rods. Because it is necessary to ensure that the two dead point positions meet the requirements at the same time, it can be locked normal...

AI Technical Summary

Problems solved by technology

The opening and closing mechanism of the bottom door of the truck unloading on the inner side of the track is generally equipped with a transmission shaft, which is connected to the bottom doors on both sides through double bell cranks and connecting rods. Closed, because it is necessary to ensure that the two dead point positions meet the requirements at the same time, it can be locked normally, and the manufacturability is poor
