Title:
HOPPER CAR
Document Type and Number:
WIPO Patent Application WO/2018/068553
Kind Code:
A1
Abstract:
A hopper car, comprising: a car body (6), a top cover (1, 2), a turning frame (24), a braking device (21), and a car coupler and buffer device (22); an underside door (25, 28) installed at a material unloading opening at an underside portion of a lower frame, an underside door opening and closing mechanism (23); and a vertical saddle (31) provided at a center of the car body (6) along a lengthwise direction and vertically on the car body (6). The vertical saddle (31) eliminates a need for sequentially closing a left underside door (25) and a right underside door (28), thereby simplifying the structure of an interlocking underside door opening and closing mechanism, and reducing the manufacturing, maintenance, and repair costs thereof. The length of a width L of the vertical saddle (31) can be adjusted to achieve relative reduction of the mass of the underside door (25, 28), lowering the force necessary for closing the underside door, further improving opening and closing performance, and realizing adjustment and control of the flow of unloaded materials. The top cover (1, 2) is a two-layered top cover combining a detachable fixed top cover (1) and a movable top cover (2) capable of being opened, effectively increasing the range of goods suitable for a covered hopper car, meeting a requirement of the covered hopper car to carry multiple kinds of goods, and achieving compatibility with various types of ground surface material loading devices.
