摘要： The present invention discloses a large-volume grain hopper car suitable for a low-loading position hopper bin. The grain hopper car includes a car body; a loading opening of the car body is provided with a top cover opening and closing mechanism, the top cover opening and closing mechanism includes a top cover and a transmission shaft, the transmission shaft is located inside the car body, the transmission shaft is connected to a top cover driving mechanism, the transmission shaft is hinged to a crank throw, and the crank throw is hinged to the top cover. The beneficial effects of the present invention are as follows: According to the grain hopper car, the arrangement of the top cover opening and closing mechanism is innovated in order to improve the volume of the car, and the transmission shaft, which is conventionally disposed on the car roof for opening and closing the top cover, is disposed in the internal space of the car body in such a way that the upper space of the car roof is utilized to the maximum extent, and the distance between the car roof and the upper limit is closest, so that the volume of the car is improved under the condition of the same car length, and the loading capacity of the whole train is improved; besides, by translating or sliding the top cover, the occupancy of the upper space in the opening process of the top cover is decreased, thus the grain hopper car is suitable for a station yard with the low-loading position hopper bin condition.

摘要： The present invention discloses a translation type top cover of a grain hopper car. The top cover includes a cover body located at a loading opening of a car body, wherein one side of the cover body is hinged to a crank throw, the crank throw is connected to a transmission shaft rotating in the car body, the other side of the cover body is hinged to a connecting lever, the connecting lever is hinged to the car body, and the transmission shaft is connected to a driving mechanism. The beneficial effects of the present invention are as follows: the top cover convenient to operate is provided to solve the problems of low working efficiency and operation with poor safety in the prior art; when the top cover is in the closed state, a self-locking air cylinder guarantees the vertical locking capacity of the top cover, a longitudinal stopping block guarantees the longitudinal locking capacity of the top cover, and a locking base and a locking rod guarantee the transverse locking capacity of the top cover; and a four-connecting-rod mechanism is formed among the car body, the crank throw, the connecting lever and the cover body to achieve translational opening and closing of the cover body and reduce space required.
