Description
[0001] The application claims priorities of a Chinese Patent Application No. 201910956702.X, filed on October 10, 2019 and entitled "a railway thermal insulation transport vehicle and side wall and assembly method thereof' and a Chinese patent application No. 201921692484.5, filed on October , 2019 and entitled "a railway thermal insulation transport vehicle and side wall thereof', the entire contents of which are incorporated herein by reference.
[0002] The disclosure relates to the field of transport vehicles, in particular, to a railway thermal insulation transport vehicle and side wall and assembly method thereof.
[0003] A railway thermal insulation transport vehicle is mainly used for long-distance transportation of fresh and perishable goods. Different from general railway vehicles of full steel welded structure, a railway thermal insulation transport vehicle not only has a full steel welded structure, but also its main parts such as underframe, side walls, end walls, roof, doors and the like, are all polyurethane integral foaming structures; in particular, a thickness of the foaming layer of its side wall reaches 150mm or more. Therefore, when it is needed to weld a column of a side wall steel structure with the underframe of the railway thermal insulation transport vehicle, a relatively thick polyurethane foaming layer at an inner side of the underframe will block it from being welded smoothly.
[0004] In order to solve the welding problem of the side wall steel structure and the underframe of the railway thermal insulation transport vehicle, in the existing techniques, the underframe does not adopt an integral foaming structure. After the side wall is integrally foamed, the column of the side wall steel structure is connected to the underframe steel structure, so that a space can be left for welding of the column of the side wall steel structure and the underframe steel structure, wherein the side wall is integrally foamed. After welding and assembling are completed, the underframe steel structure is filled with polyurethane foaming block. However, in the process of construction and use, it is found that the above-mentioned construction process is complicated, and it is prone to forming gaps during filling, which causes poor air tightness and heavy heat leakage, and in turn affects a thermal insulation performance of the whole vehicle.

[0032] The railway thermal insulation transport vehicle and side wall and assembly method thereof according to the embodiments of the disclosure, solving the problems in the existing techniques that the construction process is complicated, and it is prone to forming gaps during filling, which causes poor air tightness and heavy heat leakage, and in turn affects the thermal insulation performance of the whole vehicle.
[0033] In order to solve the above-mentioned problems, the general idea of the technical solutions of the embodiments of the disclosure is as follows:
[0034] In some embodiments of the disclosure, a column reinforcing seat is provided on the integrally foamed underframe; a welding window corresponding to the position of the end part of the column is formed at an edge, close to the underframe, of the outer wall plate of the integrally foamed side wall; and the end part of the column can be directly fixed in the column reinforcing seat through the welding window, after the side wall and the underframe are integrally foamed completely. Therefore, a connection between the integrally foamed side wall and the integrally foamed underframe is realized, thereby the air tightness of the transport vehicle is guaranteed, and the thermal insulation performance of the transport vehicle is improved, and solving the problems in the existing techniques that the construction process is complicated, and it is prone to forming gaps during filling, which causes poor air tightness and heavy heat leakage, and in turn affects the thermal insulation performance of the whole vehicle.
[0035] In order to better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the accompanying drawings and embodiments of the disclosure.
[0036] In order to solve the problems in the existing techniques that the construction process is complicated, and it is prone to forming gaps during filling, which causes poor air tightness and heavy heat leakage, and in turn affects the insulation performance of the whole vehicle, A railway thermal insulation transport vehicle and side wall thereof are provided according to the embodiments of the disclosure.
[0037] First, the side wall of the railway thermal insulation transport vehicle of the disclosure will be introduced. Fig.1, Fig.2, and Fig.3 show a front view, a B-B cross-sectional view and an A-A cross sectional view of the side wall of the railway thermal insulation transport vehicle of the disclosure.
[0038] In some embodiments of the disclosure, the side wall may include a side wall steel structure , an inner side wall 20, and a polyurethane foaming layer 30. The polyurethane foaming layer 30 is integrally foamed between the side wall steel structure 10 and the inner side wall 20.

After the polyurethane foaming layer 30 is integrally foamed between the side wall steel structure 10 and the inner side wall 20, the outer plate reinforcing ribs 11 can reinforce bonding strength between the side wall steel structure 10 and the polyurethane foaming layer 30, and the inner plate reinforcing ribs 21 can reinforce bonding strength between the inner side wall 20 and the polyurethane foaming layer 30. Meanwhile, the inner plate reinforcing ribs 21 can increase the rigidity of the inner side wall 20 and increase bearing capacity. For example, when goods in the transport vehicle are tipped over, the pressure borne by the inner side wall 20 provided with the inner plate reinforcing ribs 21 is much larger than the inner side wall not provided with the inner plate reinforcing ribs 21.
[0040] In some embodiments of the disclosure, the number of inner plate reinforcing ribs 21 can be a plurality, and the inner plate reinforcing ribs may be long strip-shaped, and a length of the inner plate reinforcing ribs 21 can be substantially equal to a height of the inner side wall 20, and the inner plate reinforcing ribs 21 are disposed at intervals in a length direction of the inner side wall 20. In some embodiments of the disclosure, in order to further improve bonding force, each of the inner plate reinforcing ribs 21 may include a fixing part 210 and a hanging part 211 connected to the fixing part 210. The hanging part can be in a bent shape to further increase the bonding force between the polyurethane foaming layer 30 and the inner side wall 20. In other embodiments of the disclosure, when the requirement for bonding force is not too high, the hanging part can also be set to be in a straight, non-bent shape.
[0041] In some embodiments of the disclosure, the number of inner plate reinforcing ribs 21 may be a plurality, and the structure of the outer plate reinforcing ribs 11 can be similar to the structure of the inner plate reinforcing ribs 21.

Meanwhile, the side pillars 12 extends into the polyurethane foaming layer 30 to increase the bonding force between the side wall steel structure 10 and the polyurethane foaming layer 30. Two ends of each of the side pillars 12 can be respectively connected to the upper frame member 151 and the lower frame member 152. In some embodiments of the disclosure, the side pillars 12 and the outer plate reinforcing ribs 11 are disposed at intervals with each other; that is, both sides of the side pillars 12 can be provided with the outer plate reinforcing ribs 11. In some embodiments of the disclosure, one of the side pillars 12 can be disposed between two inner plate reinforcing ribs 21 disposed in parallel in the height direction of the side wall steel structure 10 and another two inner plate reinforcing ribs 21 disposed in parallel in the height direction of the side wall steel structure 10. In some embodiments of the disclosure, a cross-sectional shape of each of the side pillars 12 can be substantially in a "L" shape. In some embodiments of the disclosure, the cross-sectional shape of
each of the side pillars 12 can also be in other bent shapes, which may also increase bonding force between the polyurethane foaming layer 30 and the side wall steel structure 10 to a certain extent.
[0044] In some embodiments of the disclosure, the side wall steel structure 10 may also include a column 13 disposed on a surface, opposite to the inner side wall 20, of the outer wall plate 15, and the column 13 is arranged in parallel with the plurality of the side pillars 12, and the column 13 is located between two side pillars 12. In addition, the outer plate reinforcing ribs 11 can also be provided between the column 13 and the side pillars 12.

The end part of the column 13 can be fixed in the column reinforcing seat 51 through the welding window 14, so that the side wall is fixed to the integrally foamed underframe 50, wherein the underframe 50 is integrally foamed.
[0046] In the illustration of some embodiments of the disclosure, only a case in which the number of column 13 being one is described as an example. In some other embodiments of the disclosure, the number of column 13 may be set in a plurality, such as two, three, etc., and specifically, the number of the column can be selected according to connection requirements between the side wall and the underframe 50.
[0047] In some embodiments of the disclosure, in order to greatly increase the bonding force between the polyurethane foaming layer 30 and the side wall steel structure 10 as well as the rigidity and strength of the outer wall plate 15, a plurality of outer plate reinforcing ribs 11, a plurality of side pillars 12, and one or more columns 13 can be provided on the surface, opposite to the inner side wall 20, of the outer wall plate 15 at the same time. In some other embodiments of the disclosure, according to requirements of the bonding force, rigidity and strength, only the column 13 may be provided, or only the column 13 and the plurality of outer plate reinforcing ribs 11 may be provided, or only the column 13 and the plurality of side pillars 12 may be provided, or other ways, specifically, it can be selected according to requirements.

In some embodiments of the disclosure, the side wall sealing plate 16 is fixed at the welding window 14 after the end part of the column 13 is fixed in the column reinforcing seat 51.
[0049] In some embodiments, in order to facilitate welding of the side wall sealing plate 16 and improving a welding stability of the side wall sealing plate 16, an inner surface of the outer wall plate 15 is provided with a sealing plate reinforcing board located at an edge of the welding window 14. The sealing plate reinforcing board can be fixed on the inner surface of the outer wall plate 15, and a portion of the sealing plate reinforcing board can be exposed through the welding window 14. The side wall sealing plate 16 can be fixed on the portion, exposed through the welding window 14, of the sealing plate reinforcing board. In some embodiments of the disclosure, in order to avoid interference between the sealing plate reinforcing board and the column 13, the sealing plate reinforcing board can be divided into two parts, i.e., a left sealing plate reinforcing board 17 and a right sealing plate reinforcing board 18 respectively.
[0050] In some embodiments, the side wall steel structure 10 may further include a column reinforcing board 19, and the column reinforcing board 19 can be fixed on the column reinforcing seat 51 and the lower frame member 152, so that the frame is closed to improve the bearing capacity of the side wall.
