Example Embodiment

[0019] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0020] Such as figure 1 The illustrated double-layer roof for a railway hopper car with a cover includes an inner roof 1, an outer roof 2 and an opening and closing mechanism 3. The inner roof 1 is detachably connected to the top opening of the arc car body 6 of the hopper car. The outer roof 2 is movably connected to the top opening of the arc body 6 of the hopper car through an opening and closing mechanism 3.

[0021] Combine Figure 4 As shown, the inner top cover 1 includes a frame 10, a cover plate 12 installed on the frame 10, a charging port 13 opened on the cover plate 12, and a lifting ring 14 provided on the cover plate 12 for lifting. In this embodiment, the front and rear edges of the frame 10 are all L-shaped beams 11, such as Figure 5 As shown, the L-shaped beam 11 includes a transverse side 15 and a vertical side 16. The transverse sid...

Abstract

The invention discloses a double-layer top cover for a railroad covered hopper car. The double-layer top cover comprises an inner top cover part, an outer top cover part and switching mechanisms; the inner top cover part is detachably connected with a top opening of a hopper car arc car body; the outer top cover part is movably connected with the top opening of the hopper car arc car body through the switching mechanisms; the switching mechanisms comprise rocking rods and rocking rod supports; one end of each rocking rod is fixedly connected with the end part of the outer top cover part, and one rocking rod support is connected with the other end of the rocking rod through a pin shaft correspondingly; the rocking rod supports are fixed to the end walls of the hopper car arc car body. With the adoption of the detachable inner top cover part, the goods loading application scope of the railroad covered hopper car is extended effectively; by replacing the conventional top cover with the inner top cover part provided with different types of loading hatches or directly dismounting the inner top cover part, the requirements of the railroad covered hopper car for loading various goods and being able to adapt to various ground charging equipment are met; and the double-layer top cover is simple in structure and easy to mount and dismount.

Description

technical field [0001] The invention belongs to the field of railway funnel cars, in particular to a double-layer top cover for railway covered funnel cars. Background technique [0002] The railway hopper car is a railway vehicle used for loading and unloading loose minerals such as coal, ore, sand, cement clinker and salt. For vehicles that need to be protected from rain, sand and other pollutants, the top of the vehicle body must be equipped with a movable roof. Therefore, according to the structure type, it is generally divided into railway covered hopper cars and railway covered hopper cars, and the top cover of railway covered hopper cars is a single-layer top cover, including a movable top cover that performs opening and closing actions through the top cover opening and closing mechanism. And the permanently fixed top cover that is connected with the car body as a whole, and a charging port is left on the permanently fixed top cover. At present, various types of rai...
