Embodiment Construction
[0046] The core of the present invention is to provide a bottom-opening door for the underframe of a railway gondola car. The bottom-opening door is provided with upward bending parts on the three sides overlapping with the upper cover plate, which reduces the gap between the upper cover plate and the upper cover plate. gap, and a second seal is set between the first side of the bottom door panel and the middle beam of the underframe, reducing the gap between the side and the middle beam, and avoiding the leakage of goods. On this basis, another core of the present invention is to provide a railway gondola car chassis using the above-mentioned bottom opening door.
[0047] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0048] It should be noted that the orientation word "out...

The invention discloses a bottom-opening door used for a railway open wagon chassis. The chassis comprises a center sill and an upper cover plate. The bottom-opening door comprises a bottom door plate, the first side edge of the bottom door plate is hinged to the center sill, and the other side edges of the bottom door plate and the upper cover plate are overlapped. One or more of the other three side edges are provided with upward bent parts so that the gap between the bottom door plate and the upper cover plate can be shrunk. By the adoption of the structure, the upward bent parts can shrink the gap between the bottom door plate and the upper cover plate, through reasonably arranging the angle and position of the upward bent parts, gaps between the three side edges and the upper cover plate can be shrunk to be smaller than the size of goods particles, compared with horizontal plates serving as the three side edges, the goods particles can be prevented from leaking from the gaps between the three side edges and the upper cover plate, and then the loss of goods is avoided. The invention further discloses the railway open wagon chassis applying the bottom-opening door.
Description
technical field [0001] The invention relates to the technical field of railway vehicles, in particular to an underframe of a railway gondola car and a bottom opening door thereof. Background technique [0002] Railway open car is mainly used to transport steel, timber, building materials and bulk cargo (including coal, coke and ore, etc.). Gondola cars can be divided into side door gondola cars and bottom door gondola cars. The unloading speed of open-door wagons with bottom doors is greater than that of open-door wagons with side-hung doors, and the unloading rate of open-door wagons with bottom-hung doors is greater than that of open-door wagons with side-hung doors. Therefore, open-door wagons with bottom-hung doors are more widely used. [0003] Please refer to Figure 1 to Figure 3 , figure 1 and figure 2 Respectively, a front view and a top view of the assembly of a bottom-opening door and the underframe of a railway open car in the prior art, image 3 for figu...
