Embodiment Construction

[0022] see figure 1 , A movable roof of a railway hopper car provided by an embodiment of the present invention includes a roof 1 , two rockers 5 , two rocker supports 8 , two cylinders 6 and two cylinder mounts 4 . The funnel car adopts the arc car body 3. According to the loading width of the loading hopper, a 1.1-meter-wide loading port is opened at the center of the arc car body 3 top. A top cover 1 with a special-shaped arc is installed above, and the top cover 1 can be flexibly opened and closed by wind or manual control as required.

[0023] see figure 2 , the top cover 1 is flexibly connected to the top opening of the arc car body 3 of the funnel car. There is a rocker 5 on one side of the arc car body 3, and one end of the rocker 5 is fixedly connected with the end of the top cover 1. The other end of rocking bar 5 is hinged on a rocking bar support 8, and this rocking bar support 8 is fixed on the bottom of arc car body 3 with bolt, and one end of a cylinder 6 is ...

Abstract

The invention discloses a movable top cover for a railroad hopper car, which belongs to the technical field of railroad freight. The hopper car comprises a top cover, a rocker, a rocker support, an air cylinder and an air cylinder mounting seat, wherein the top cover is movably connected with an opening at the top of an arc car body of the hopper car; one end of the rocker is fixedly connected with the end of the top cover; the other end of the rocker is articulated with the rocker support; the rocker support is fixed at the bottom of the arc car body; one end of the air cylinder is movably connected with the middle of the rocker; the other end of the air cylinder is articulated with the air cylinder mounting seat; the air cylinder mounting seat is fixed on the arc car body; and a spring balance device is arranged between the rocker and the car body. The movable top cover can reduce the rated pressure or the diameter of the air cylinder of the conventional hopper car with the cover greatly, so that the manufacturing cost of the movable top cover is lowered, and the opening and closing performance of the movable top cover is improved.

Description

technical field [0001] The invention belongs to the technical field of railway freight, and in particular relates to a movable top cover of a railway hopper car. Background technique [0002] With the increasing awareness of human safety and environmental protection, the safety and environmental problems of railway freight transportation have become increasingly prominent. For some bulk goods that need to be protected from moisture, moisture or harmful to the environment, they need to be isolated and protected during transportation, such as lime, phosphate, sulfur, grain, cement and china clay. The transportation of funnel trucks with movable top covers has the advantages of cost-effectiveness, environmental protection and low carbon, and safe and reliable cargo transportation. The torque produced by the center of gravity of the movable top cover of the long hopper car to the center of the rocker support is much larger in the fully open state than in the closed state, so th...
