Abstract

The invention relates to an unloading device of a railway freight transportation hopper car. The unloading device is a link mechanism arranged between a pneumatic unloading device and a hand-operated unloading device of the railway freight transportation hopper car, belonging to the rail traffic field. The unloading device comprises a clutch and a main air pipe of a pneumatic system, wherein the clutch is arranged on a poking fork which has a poking pin; the poking fork is arranged on a main transmission shaft which is arranged on a support; and the main transmission shaft is provided with a handle. The key technology of the unloading device comprises the following steps that: the handle is connected with a connecting rod, and the other end of the connecting rod is connected with a changeover cock which is arranged on the main air pipe of the pneumatic system. The unloading device adopts a linkage mechanism, that is, the handle, the connecting rod, the changeover cock and the car body are formed into a four-linkage mechanism; therefore, by means of the transmission function of the four-linkage mechanism and the switching of the changeover cock, hand-operated action is realized when pneumatic function is shut down, thereby solving the problem of pneumatic misoperation during hand-operated unloading. In addition, the linkage mechanism can reach the goal of reliable operation through controlling the length and the position of the connecting rod so as to eliminate hidden danger.

Description

technical field [0001] The invention relates to an unloading device for a railway freight hopper car, which is a linkage mechanism between a pneumatic and a manual unloading device for a railway freight hopper car, and belongs to the field of railway transportation. Background technique [0002] The railway freight hopper car (hereinafter referred to as the hopper car) is mainly used to transport bulk goods such as ballast, ballast, and coal. Most of the hopper cars in our country are equipped with pneumatic unloading device and manual unloading device, and the clutch is used to switch between the pneumatic unloading device and manual unloading device. Its working principle is that when the clutch is disconnected, the manual device loses its function, and the pneumatic device can realize the unloading function (see figure 1 shown); when the clutch is closed, the manual device can realize the unloading function, and the pneumatic device can also realize the unloading functio...
