Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 5-7, fig. 5 is a front view of an end wall of a railway truck according to an embodiment of the present invention; FIG. 6 is a left side view of FIG. 5; fig. 7 is a top view of fig. 5.
The embodiment of the invention provides a railway open wagon and an end wall 10 thereof, wherein the end wall 10 comprises an upper end beam 1 and an end wall plate 2 as shown in fig. 5-7; the end wall plate 2 comprises a first section 21 and a second section 22 which are sequentially connected from bottom to top, wherein the bottom end of the first section 21 is connected with the floor 20 of the railway open wagon, and the height of the first section is larger than the height when the reinforcing ribs of the wagon shifting arm rotate to the highest point, so that the external space of the end wall 10 is enough, and the wagon shifting arm cannot interfere with the end wall 10 in the swinging process; the second section 22 is arranged protruding outwards and is connected at its top end to the upper end rail 1, wherein "outwards" refers to the side facing the outside of the railway truck. That is, in the case where the end face of the side wall plate is spaced apart from the end face of the impact seat and the length of the railway truck is fixed, the arrangement of the first section 21 provides enough space for the rotation of the truck poking arm to avoid interference between the two, while the protruding arrangement of the second section 22 increases the distance between the wall plates 2 at both ends of the railway truck, fully utilizes the end limit, and effectively increases the volume of the railway truck.
Meanwhile, since the second section 22 is arranged to protrude outwards, and a bending section exists at the connection part between the second section and the first section 21, that is, the end wall plate 2 is not of a flat plate structure, but the bending modulus of the plate provided with bending is larger than that of the flat plate, and the deformation resistance is strong, therefore, the impact deformation resistance of the end wall 10 against cargoes can be effectively improved by the end wall plate 2 provided by the embodiment.
In addition, the end wall 10 provided in this embodiment further includes a column 3, the top end of the column 3 is connected with the upper end beam 1, the bottom end of the column 3 is connected with the middle beam 30 of the railway open wagon, and the rigidity and impact resistance of the whole end wall 10 can be further improved by the arrangement of the column 3.
As shown in fig. 6, in the present embodiment, the lower portion of the upright 3 is an outer upright 31 disposed outside the first section 21, and the upper portion is an inner upright 32 disposed inside the second section 22, and since the upright 3 is connected between the upper end cross member 1 and the center sill 30, the outer upright 31 outside the first section 21 does not interfere with the rotation of the arm. In this embodiment, the specific structure of the upright 3 is not limited, as shown in fig. 5, the upright 3 is set to an integral structure, that is, the inner upright 32 and the outer upright 31 are set to be integral, or may be set to a split structure, and when the two are set to an integral structure, the integral strength of the upright 3 can be increased, and the stability is better.
In the above embodiment, to further improve the impact resistance of the end wall 10, the end wall 10 further includes the transverse band 4 fixed to the end wall plate 2. As shown in fig. 6, the second section 22 of the end wall plate 2 is provided with a straight section 221, and the straight section 221 is fixedly provided with a transverse band 4, wherein the straight section 221 means that the surface of the plate is in a planar structure. In order to ensure that the volume of the railway open wagon is maximum, the height of the first section 21 should be as low as possible under the condition that rotation interference with the poking arm does not occur, so that under the condition of a certain total height, the second section 22 is relatively higher, and because the goods positioned at the lower part of the railway open wagon are relatively in a compacted state and relatively stable in the process of transporting the goods, and the goods positioned at the upper part are relatively in a loose state, the goods positioned at the upper part are easy to shake back and forth under the action of inertia, and then impact is caused to the end wall plate 2, in the embodiment, the second section 22 is provided with the transverse belt 4, and the impact resistance of the second section 22 can be effectively improved by the transverse belt 4.
Of course, in the present embodiment, the first section 21 may be provided with the transverse bands 4, and the portions of the second section 22 other than the flat section 221 may be provided with the transverse bands 4, and the number of the transverse bands 4 in the first section 21 and the second section 22 is not limited. However, the arrangement of providing the transverse strap 4 only in the straight section 221 of the second section 22 simplifies the overall structure and reduces the dead weight of the end wall plate 2 while ensuring the strength of the end wall plate 2.
In the present embodiment, the specific installation position of the transverse belt 4 is not limited, and the transverse belt 4 is installed inside the straight section 221 only when the straight section 221 of the second section 22 is provided with the transverse belt 4. The both ends of the transverse belt 4 are respectively connected with the two side wallboards, so that when the transverse belt 4 is arranged on the inner side of the straight section 221, the structural arrangement of the side wallboards does not need to consider the transverse belt 4, namely, the structure is not required to be additionally arranged to be connected with the end part of the transverse belt 4, and the applicability is good.
If the first section 21 is provided with the transverse belt 4, the transverse belt 4 needs to be arranged on the inner side of the first section 21 to avoid interference with the vehicle shifting arm.
In the above embodiment, the second section 22 further includes two inclined sections of the first inclined section 222 and the second inclined section 223, wherein the first inclined section 222 is located between the top of the first section 21 and the straight section 221, and the second inclined section 223 is located between the straight section 221 and the upper end cross member 1, that is, the second section 22 is provided with two bends in the longitudinal direction. In this embodiment, the second section 22 may be configured to be convex, or the second section 22 may be configured to have two straight sections 221 with only one bending portion. Compared with a structure with one bending part, the structure with two bending parts can effectively improve the impact resistance strength of the end wallboard 2, and meanwhile, the two inclined sections are simpler in processing technology compared with the structure with two circular arc sections.
In the above embodiment, the transverse belt 4 disposed inside the second section 22 is configured to have a triangular cross section, and in the state of the maximum rotation unloading angle of the railway open wagon, the angle between the lower side of the triangle and the horizontal plane is larger than the angle at which the railway open wagon carries the cargo, wherein the angle of repose is the horizontal stacking angle of the cargo. That is, when the railway open wagon rotates to the maximum angle in the unloading process, the transverse belt 4 does not obstruct the unloading of the goods, so that the goods are completely and smoothly unloaded, and dead angles are not remained.
Similarly, if the first section 21 of the end wall plate 2 is also provided with a transverse band 4, the transverse band 4 has the same structure and design requirements as the transverse band 4. While the specific shape of the lateral band 4 is not limited if it is provided outside the second section 22.
In the above embodiment, as shown in fig. 6, the cross section of the upper end beam 1 is quadrilateral, and the lower end surface is an inclined surface, wherein the side edge of the lower end surface facing the side of the second section 22 is lower than the side edge facing the outside of the railway open wagon, that is, the contact area between the upper end beam 1 and the second section 22 is larger, so that the free length of the second section 22 can be reduced, and the rigidity and the impact deformation resistance of the lower end surface can be effectively improved. Of course, in the present embodiment, the cross-sectional area of the upper end beam 1 may be increased uniformly to increase the contact area with the second section 22, but the volume of the upper end beam 1 may be reduced by increasing the area of only the side surface in contact with the second section 22, thereby reducing the dead weight of the overall structure.
In the present embodiment, the specific structure of the upper end cross member 1 is not limited, and in the present embodiment, the cross member may be a quadrangular cross member, but may be a triangular cross member or a polygonal cross member.
In the above embodiment, the headwall 10 further includes a reinforcing plate 5, and the reinforcing plate 5 is disposed between the headwall 2 and the floor 20 of the open wagon to increase the strength of the connection between the headwall 2 and the floor 20.
In the above embodiment, the headwall 10 further includes a corner reinforcing iron 6, and the corner reinforcing iron 6 is provided between the upper end rail 1 and the upper side rail 40 of the railway gondola car to increase the connection strength of the two.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
