Referring to fig. 3 and 8-10, fig. 8 is an enlarged left side view of the side plate 4 and the connecting plate 5 shown in fig. 3; FIG. 9 is a schematic left side view of the railway truck in an overturned state; fig. 10 is a left side schematic view of the railway truck being overturned to an extreme position when being unloaded.

As shown in fig. 8, the side plate 4 is configured from top to bottom as a first arc-shaped plate 41, a first flat plate 42, a second arc-shaped plate 43, and a second flat plate 44. Specifically, the first arc-shaped plate 41, the first flat plate 42, the second arc-shaped plate 43 and the second flat plate 44 can be formed independently and then welded into a whole; or can be directly formed integrally.

Wherein, the first flat plate 42 extends along the vertical direction, and the top thereof is tangentially connected with the bottom of the first arc-shaped plate 41, and the top of the first arc-shaped plate 41 is bent inwards relative to the bottom thereof; the bottom of the first flat plate 42 is tangentially connected with the top of the second arc-shaped plate 43, and the bottom of the second arc-shaped plate 43 is inwards bent relative to the top; the bottom of the second arcuate plate 43 is tangentially connected to the top of the second flat plate 44, and the bottom of the second flat plate 44 is inwardly inclined relative to the top thereof.

Of course, the bottom of the side plate 4 may be an arc-shaped plate or a flat plate without the connecting plate 5, and may be directly connected to the bottom plate 7, but in contrast, the space for adjusting the height dimension is relatively small.

Referring to fig. 3-7, fig. 6 is a view along direction C-C of fig. 4, and fig. 7 is a view along direction D-D of fig. 5;

as shown in fig. 4-5, the side posts 2 and the pillow posts 1 are both configured as trapezoidal posts with the top smaller than the bottom, so that the side posts 2 and the pillow posts 1 are fixed at the bottom and the stability of the two is improved. In addition, when the radian of the first arc-shaped plate 41 is configured to be smaller than that of the second arc-shaped plate 42, the top portions of the side posts 2 and the pillow posts 1 are set to be small in size, that is, sufficient abutting space can be increased for the two sides of the side plate 4, so that the top portions of the side posts and the pillow posts can be set to be small in size to further reduce the self weight of the side wall.

Specifically, as shown in fig. 4 to 5, the side posts 2 and the pillow posts 1 are configured as follows: the bottom of the inner side surface inclines from outside to inside relative to the top, and the outer side surface extends along the vertical direction. That is, the side posts 2 and the pillow posts 1 are both configured as trapezoidal posts having a vertical outer side surface and a small top and a large bottom, and having an inclined inner side surface. In this way, a part of the wear plate 6 may be disposed on the outer side surface of the side post 2 and the outer side surface of the bolster post 1, for easy understanding, refer to fig. 3.

More specifically, as shown in fig. 4 to 5, the outer side surfaces of the side posts 2 and the pillow posts 1 are flush with the outer side surface of the first flat plate 42. That is, the outer side surfaces of the side posts 2 and the pillow posts 1 and the outer side surface of the first flat plate 42 are in a vertical plane. So set up, make side column 2 with pillow 1's lateral surface with the outside face parallel and level of side can be in the assurance to under the prerequisite that the both sides of curb plate 4 provided sufficient conflict space, bigger reduction side column 2 with pillow 1's dead weight, and then reduce the dead weight of whole side wall.

More specifically, as shown in fig. 6 to 7, both left and right side surfaces (upper and lower surfaces shown in fig. 6 to 7) of the pillow post 1 and the side post 2 extend in the vertical direction, and are disposed so as to facilitate connection between the left and right side surfaces and the left and right side surfaces of the corresponding side plate 4.

In addition, as shown in fig. 4 to 5, the upper side member 3 is configured such that: the ladder-shaped beam is formed by a top surface, a bottom surface and an outer side surface, wherein the inner side of the top surface and the inner side of the bottom surface are fixedly connected with the outer side surface of the side plate 4.

So set up, can make the lateral surface shutoff of curb plate 4 the inboard opening of trapezoidal roof beam, and with the top surface and the bottom surface welding of trapezoidal roof beam, it is convenient for fixed between 4 tops of curb plate and the roof beam 3 of side to see this kind of setting up mode, and compare with the roof beam 3 of side set up to have the inboard not open roof beam then will curb plate 4 tops overlap joint in not open roof beam, fixed reliability is higher, does benefit to the intensity that improves the side wall.

Referring to fig. 11, fig. 11 is a schematic diagram showing the size of the wear plate 6 and the size of the car backing plate 8 of the car dumper.

As shown in fig. 11, the tippler matched with the railway open wagon is provided with a car leaning plate 8, and when unloading, the inner side surface of the car leaning plate 8 faces the outer side surface of the wearing plate 6; the top surface of the wearing plate 6 can be higher than or flush with the top surface of the corresponding car leaning plate 8, and the bottom surface of the wearing plate 6 can be lower than or flush with the bottom surface of the corresponding car leaning plate 8 in the no-load state and the full-load state of the railway open wagon.

It should be understood that in practical application, after the railway gondola car type is fixed, the matching car dumper is fixed, that is, the height dimension of the car leaning plate 8 of the car dumper corresponding to the railway gondola car is fixed, that is, a ', B', C ', D' shown in fig. 9 is fixed. However, due to the change in the load of the railway truck, the height dimension of wear plate 6 facing carriage plate 8, i.e., the dimension of figure D, is changed. For example, the dimension D is smaller when fully loaded and the height of the top surface of wear plate 6 (a + B and C + D) is correspondingly smaller, and the dimension D is larger when empty and the height of the top surface of wear plate 6 (a + B and C + D) is correspondingly larger.

With the above arrangement, it is possible to avoid the risk that the wear plate 6 is cut out due to the edge of the wear plate 6 being abutted by the car plate 8, because the top surface of the wear plate 6 is higher than the top surface of the corresponding car plate 8 (a + B > a '+ B' and C + D > C '+ D') or the bottom surface of the wear plate 6 is lower than the bottom surface of the corresponding car plate 8 (D < D 'and B < B').

Specifically, the value of the top surface of wear plate 6 above the corresponding top surface of bed 8 (shown as G and H values) and the value of the bottom surface of wear plate 6 below the corresponding bottom surface of bed 8 (shown as E and F values) can be determined based on the amount of difference in height dimensions between the full and empty railway truck.

Generally, in an empty state, E is more than or equal to 50mm, F is more than or equal to 50mm, G is more than or equal to 100mm, and H is more than or equal to 100 mm. Of course, it is not limited to this example value.

The invention also provides a railway open wagon which comprises the bottom plate 7 and the side wall.

The railway gondola car and the side wall thereof provided by the invention are described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts of the present invention. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
