DETAILED DESCRIPTION

[0027] The core of the present invention is to provide a vehicle body side wall to make the vehicle body lightweight, reduce operating energy consumption, and avoid the problem of poor operating environment caused by closure; Another core of the present invention is to provide a railway freight car body and a railway double-deck transportation vehicle with the above-mentioned car body side walls.

[0028] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0029] like Figure 1 and Figure 2 As shown, the vehicle body side wall 100 disclosed in the embodiment of the present invention includes a column assembly, an upper crossbeam 108 and a diagonal brace assembly. There are two groups of column assemblies, which are respectively located at the two ends of the vehicle body, and a lifting installation space for the lifting auxiliary device 600 is formed on the column assembly. The lifting installation space is directly formed on the column assembly, that is, the lifting auxiliary device 600 is arranged using the gap space of the vehicle body side wall 100, thereby improving space utilization and making the loading space of the vehicle larger.

[0030] The lower end of the column assembly is used to be connected to the lower chassis 200 of the vehicle body. One end of the upper crossbeam 108 is connected to one set of column assemblies, and the other end is connected to the other set of column assemblies. That is, the upper crossbeam 108 is connected between the two column assemblies, and the upper crossbeam 108 is used to support the upper chassis 300. In order to improve the supporting capacity of the upper crossbeam 108, the suspended part through which the upper crossbeam 108 passes is supported by a diagonal brace assembly.

[0031] There are at least two groups of diagonal brace assemblies, and each group of diagonal brace assemblies is arranged at intervals between the upper crossbeam 108 and the lower chassis 200. One end of the diagonal brace assembly is connected to the upper crossbeam 108, and the other end is used to connect to the lower chassis 200, that is, the diagonal brace assembly is supported between the upper crossbeam 108 and the lower chassis 200, so that the upper crossbeam 108 has a better supporting capacity. The diagonal brace assembly is easy to form a triangular structure, which can play a role in supporting the upper chassis 300 more stably.

[0032] The vehicle body side wall 100 provided by the present invention is provided with column assemblies at both ends of the vehicle body. The column assemblies are the main supporting bodies of the vehicle body side wall 100. The two groups of column assemblies are connected by an upper crossbeam 108. The upper crossbeam 108 can serve as the main supporting body of the upper chassis 300. The diagonal brace assembly is arranged between the upper crossbeam 108 and the lower chassis, and is used to support the upper crossbeam 108, improve the supporting capacity of the upper crossbeam 108, and thus support the upper chassis 300. The vehicle body side wall 100 of the present invention adopts an open frame structure to avoid high temperature and stuffiness in the vehicle in summer, and improves the working environment of the operator. Moreover, since the vehicle body side wall is not provided with a closed compartment, part of the skin material is saved, and it has a lightweight structure, reduces traction energy consumption, reduces vehicle traction costs, and achieves the effects of energy saving and consumption reduction, reducing carbon emissions, and increasing economic and social benefits.

[0033] In a specific embodiment of the present invention, the column assembly includes a first column 101, a second column 102 and a third column 103 arranged in parallel and arranged in sequence from the end to the middle of the vehicle body. The two column assemblies are symmetrically arranged along the vehicle body, and the upper cross beam 108 is connected between the third columns 103 of the two column assemblies.

[0034] An escalator 109 is provided between the first column 101 and the second column 102. The escalator 109 may be composed of a plurality of beams connected between the first column 101 and the second column 102. The spacing between the beams of the escalator 109 should be determined according to the climbing step length of the operator. By providing the escalator 109 at both ends of the vehicle body, it is convenient for the operator to climb to the upper chassis 300. At the same time, the beams of the escalator 109 play the role of connecting, supporting and reinforcing the first column 101 and the second column 102.

[0035] A lifting installation space for installing the lifting auxiliary device 600 is formed between the second column 102 and the third column 103. Specifically, an outer wall panel can be arranged between the second column 102 and the third column 103, and the outer wall panel can be on the same plane as the outer facades of the second column 102 and the third column 103, so that the second column 102, the third column 103 and the outer wall panel form a groove structure facing the inner side of the vehicle body, and the lifting auxiliary device 600 can be arranged in the groove structure surrounded by the three. In this embodiment, the lifting auxiliary device 600 is arranged in the space between the second column 102 and the third column 103, so that the lifting auxiliary device 600 does not occupy the effective space of the upper chassis 300 and the lower chassis 200, thereby not affecting the bearing capacity of the vehicle body.

[0036] It should be noted that the column assembly is not limited to the three columns of the first column 101, the second column 102 and the third column 103. A solution with two columns or more than three columns can also be designed according to needs, and is not limited to the number disclosed in the above embodiment.

[0037] In a specific implementation of the present invention, the diagonal brace assembly may include a plurality of diagonal braces arranged in sequence from the end to the middle of the vehicle body, the upper cross beam 108 is parallel to the side beam 201 of the lower chassis 200, and each diagonal brace and the upper cross beam 108 have an angle greater than 0° and less than 90°. The inclination direction of each diagonal brace can be changed in sequence, for example, if one of two adjacent diagonal braces is inclined to the left, the other is inclined to the right, so that the two adjacent diagonal braces can form a triangular structure, providing a better support effect for the upper cross beam 108. The inclination angle of the diagonal brace can be designed by those skilled in the art according to requirements, for example, it can be 45°, or 60°, etc.

[0038] There can be two groups of diagonal brace assemblies, which are symmetrically arranged at both ends of the upper cross beam 108. The diagonal brace assembly at least includes a first diagonal brace 104, a second diagonal brace 106 and a third diagonal brace 107 arranged in sequence from the end to the middle of the vehicle body.

[0039] The first diagonal brace 104 and the second diagonal brace 106 are arranged in parallel, and the second diagonal brace 106 and the third diagonal brace 107 are inclined in opposite directions. Such an arrangement allows the first diagonal brace 104 and the third column 103, as well as the second diagonal brace 106 and the third diagonal brace 107 to form a quasi-triangle, and utilizes the stability of the triangle to provide a more stable support for the upper crossbeam 108.

[0040] For ease of understanding, the space enclosed by the first diagonal brace 104, the column assembly, the upper cross beam 108 and the side beam 201 of the lower chassis 200 is defined as the first space; the space enclosed by the second diagonal brace 106, the third diagonal brace 107, the upper cross beam 108 and the side beam 201 of the lower chassis 200 is defined as the second space, and at least one of the first space and the second space is provided with an exterior wall panel 111. It should be noted that the exterior wall panel 111 can be kept coplanar with the exterior facade of the diagonal brace assembly and the upper cross beam 108 to maintain the consistency of the exterior facade of the vehicle body side wall.

[0041] In order to further improve the stability, the upper and lower ends of the first diagonal brace 104 and the second diagonal brace 106 are connected by auxiliary crossbeams 105. The auxiliary crossbeam 105 at the upper end is connected to the upper crossbeam 108, and the auxiliary crossbeam 105 at the lower end is connected to the side beam 201 of the lower chassis 200. That is, the first diagonal brace 104, the second diagonal brace 106 and the two auxiliary crossbeams 105 form a parallelogram. Since the first diagonal brace 104 and the second diagonal brace 106 are arranged obliquely, they are in close contact with the upper crossbeam 108 and the side beam 201 of the lower chassis 200 (such as Figure 5 The connection between the first and second diagonal braces 104 and 106 is relatively fragile. In this embodiment, auxiliary crossbeams 105 are respectively provided at the upper and lower ends of the first diagonal brace 104 and the second diagonal brace 106 to stabilize the structural strength of this position and prevent deformation.

[0042] In order to further strengthen the structural strength of the diagonal brace, in this embodiment, corner reinforcement seats 110 are provided at the four inner corners of the quadrilateral formed by the first diagonal brace 104, the second diagonal brace 106 and the two auxiliary cross beams 105. It should be noted that the thickness of the reinforcement seat 110 can be the same as the thickness of the first diagonal brace 104, the second diagonal brace 106 and the two auxiliary cross beams 105. It should be noted that the reinforcement seat 110 can also be provided at the position where the third diagonal brace 107 is connected to the upper cross beam 108 and the side beam 201 on the side away from the second diagonal brace 106. In this embodiment, by adding the reinforcement seat 110, the connection of each diagonal brace can be strengthened to further stabilize the structural strength of the position and avoid deformation.

[0043] The reinforcing seat 110 may be a triangular structure, which includes two plane edges, which are used to be connected to the diagonal braces (the first diagonal brace 104, the second diagonal brace 106, and the third diagonal brace 107) and the components connected to the diagonal braces. The reinforcing seat 110 also includes a curved surface edge, which is a concave surface that is concave toward the vertex direction of the two plane edges. Such a configuration can avoid stress concentration and provide a better reinforcement effect.

[0044] It should be noted that the beams and columns of the vehicle body side wall 100 may be profiles such as channel steel or rectangular tubes, or other structures.

[0045] like Figure 5 , Figure 8 and Fig. 9 As shown, the embodiment of the present invention further discloses a railway freight car body, which includes a lower chassis 200 , a car body side wall 100 , an upper chassis 300 and a lifting auxiliary device 600 .

[0046] The railway freight car body generally has two layers of loading space, an upper chassis 300 and a lower chassis 200. When passing through some special road conditions such as tunnels, the vehicle has a height limit requirement, which places certain requirements on the height of the railway freight car body. Currently, for the railway freight car body with two layers of loading space, the upper chassis 300 cannot be designed too high, which will inevitably affect the space between the upper chassis 300 and the lower chassis 200.

[0047] In order to meet the shipping requirements, the lower chassis 200 is usually designed to be low in the middle and high at both ends (because the vehicle has wheelsets at both ends, the ends cannot be designed to be lower than the middle due to the limitation of the wheelsets). Because the positions of the two ends of the lower chassis 200 cannot be made low, when the car is shipped to the lower chassis 200, the height space at the ends is insufficient and the car cannot pass. In order to meet the shipping requirements, the upper chassis 300 is divided into three sections, namely the upper middle chassis 302 and the upper end chassis 301 located at the two ends of the upper middle chassis 302. The upper end chassis 301 is hinged to the upper middle chassis 302 through a rotating support, so that the upper end chassis 301 can adjust the angle.

[0048] When the car on the lower chassis 200 is shipped, it is necessary to raise the height of the upper end chassis 301 to increase the height space at the end of the lower chassis 200 so that the car can pass. After shipping is completed, the height of the upper end chassis 301 is lowered again to ship the car on the upper chassis 300.

[0049] Since the top of the car is an arched shape with a higher middle, in this embodiment, the upper middle chassis 302 and the upper end chassis 301 are designed as an arched structure with the middle arched upward. Such a configuration can not only adapt to the arc-shaped structure of the car top with a high middle and low sides, but also reduce the loading height of the upper car, and at the same time maximize the use of the space for loading cars on the lower layer, making the maximum use of the loading space so that the height of the loaded car does not exceed the railway vehicle limit.

[0050] In this embodiment, the upper chassis 300 and the lower chassis 200 are designed with the above-mentioned structure, so that the loading space can be utilized to the maximum extent, and the height of the loaded vehicle does not exceed the railway vehicle limit.

[0051] The vehicle body side wall 100 is the vehicle body side wall 100 disclosed in the above embodiment, and the specific structure of the vehicle body side wall 100 is not described in detail herein. The vehicle body side wall 100 is symmetrically arranged on the lower chassis 200, and the column assembly and the diagonal brace assembly are both fixed on the side beam 201 of the lower chassis 200.

[0052] The lifting auxiliary device 600 is arranged in the lifting installation space, and is used to assist in lifting the upper end chassis 301. The lifting auxiliary device 600 can be a labor-saving structure composed of a pulley block, a wire rope and a counterweight; the lifting auxiliary device 600 can also be a spring balancer. The specific structure of the lifting auxiliary device 600 is not limited in this embodiment, as long as it can assist the upper end chassis 301 in rotating, so as to reduce the rotation resistance of the upper end chassis 301 and achieve the effect of labor saving.

[0053] The upper end chassis 301 can be switched between a working position and a lifting position. When the upper end chassis 301 is in a working position (usually a horizontal position or a position close to the horizontal position at a preset angle to the horizontal position) and needs to be lifted to a lifting position (a position where the end of the upper end chassis 301 is tilted, so that the end height of the upper end chassis 301 is raised to facilitate the loading of the car on the lower chassis 200), the operator can apply an upward thrust to the upper end chassis 301, and the upper end chassis 301 will rise with the help of the lifting auxiliary device 600. When the upper end chassis 301 rises to the required position, the operator applies a downward pulling force to stop it from rotating, and then fixes the upper end chassis 301. When the upper end chassis 301 needs to be lowered, the operator can continue to apply a downward pulling force and fix the upper end chassis 301 in the working position.

[0054] like Figure 4 As shown, in order to support and fix the upper end frame 301 in the working position and the lifting position, in this embodiment, a fixed support seat 112 and a movable support seat 114 are added. The fixed support seat 112 and the movable support seat 114 can be set on one side of the vehicle side wall 100, and can also be set on the vehicle side walls 100 on both sides.

[0055] A plurality of fixed support seats 112 are provided on the upper crossbeam 108 and / or the column assembly, and when the upper end chassis 301 is lowered to the working position, the upper end chassis 301 is supported on the fixed support seats 112. The fixed support seats 112 are used to limit the lowest limit position of the upper end chassis 301, so that when the upper end chassis 301 is lowered to contact with the fixed support seats 112, it is constrained by the fixed support seats 112 and cannot continue to descend.

[0056] The premise that the upper end base frame 301 can be supported on the movable support seat 114 is that during the rising process of the upper end base frame 301, it needs to pass over the movable support seat 114 and then descend before it can be supported on the movable support seat 114; therefore, the movable support seat 114 needs to change its position so that when the upper end base frame 301 rises, it does not interfere with the movement of the upper end base frame 301; when it descends, it can interfere with the descent of the upper end base frame 301.

[0057] Since the movable support seat 114 is higher than the fixed support seat 112, the movable support seat 114 cannot be set on the upper crossbeam 108 with a lower height, and the movable support seat 114 can only be set on the column assembly. When the upper end chassis 301 rises to the lifting position, the upper end chassis 301 is supported on the movable support seat 114, and the movable support seat 114 can be movably set on the column assembly in the supporting position and the avoiding position.

[0058] The movable support seat 114 can be hinged on the column assembly through a hinge shaft, and the extension direction of the hinge shaft can be the extension direction of the column assembly, that is, the height direction. The movable support seat 114 rotates along the hinge shaft and can rotate to a path outside the swing range of the upper end chassis 301. After the upper end chassis 301 swings to a height higher than the movable support seat 114, the movable support seat 114 is rotated along the hinge shaft to the path of the swing range of the upper end chassis 301, and then the upper end chassis 301 is lowered, so that the upper end chassis 301 can be supported on the movable support seat 114, so as to support the upper end chassis 301 in a raised position.

[0059] like Figure 3 and Figure 4 As shown, in this embodiment, a tool box 500 may be further included, and the tool box 500 may include an upper tool box 501 and a lower tool box 502. The upper tool box 501 is arranged on the upper side of the upper cross beam 108, and the lower tool box 502 is arranged in the gap of the diagonal brace assembly. In this embodiment, the tool box 500 is arranged by utilizing the gap space of the vehicle side wall 100, so that the tool box 500 does not occupy the vehicle loading space, thereby maximizing the loading capacity.

[0060] In addition, in this embodiment, an upper tool box 501 is arranged on the upper side of the upper cross beam 108, and a lower tool box 502 is arranged in the gap of the diagonal brace assembly, so that the operator can conveniently take tools from the upper tool box 501 and the lower tool box 502 at the corresponding height when working on the upper chassis 300 and the lower chassis 200. It should be noted that both the upper tool box 501 and the lower tool box 502 can be provided with openable and closable doors, and equipped with corresponding locking tools to achieve the storage of tools and prevent the tools in the tool box from falling out due to vibration during the operation of the vehicle.

[0061] like Figure 4 and Figure 7 As shown, in order to improve the safety of the operators when working on the upper chassis 300, in this embodiment, the railway freight car body may also include a safety protection device 400, which is arranged on the upper side of the upper crossbeam 108, and the safety protection device 400 is arranged between any two adjacent upper tool boxes 501, and between the upper tool box 501 and the column assembly. The safety protection device 400 can increase the protection height above the upper crossbeam 108 to prevent the operators from falling due to unstable standing. The height of the column assembly should be higher than the height of the upper chassis 300, and the safety protection device 400 can be designed to be the same height as the column assembly, or close to the height of the column assembly.

[0062] Specifically, the safety protection device 400 may include a connection seat 401, a guard plate 402, a connection rod 403 and a handrail 404. The connection seat 401 is fixed to the upper beam 108, for example, the connection seat 401 may be welded to the top of the upper beam 108 by welding.

[0063] The guard plate 402 is detachably fixed to the outer surface of the connecting seat 401. The guard plate 402 can be designed to be coplanar with the facades of the exterior wall panel 111 and the upper cross beam 108 to maintain the consistency of the facades of the side walls of the vehicle body and make the appearance of the vehicle body smooth.

[0064] The connecting rod 403 is detachably fixed to the connecting seat 401. The connecting rod 403 may include a transverse connecting rod and a longitudinal connecting rod fixed together. Specifically, a connecting plate may be provided at the end of the longitudinal connecting rod, and the connecting plate may be fixed to the connecting seat 401 by a fastener. In addition, the guard plate 402 may also be detachably fixed to the connecting seat 401 by a fastener. In this embodiment, the guard plate 402 and the connecting rod 403 are detachably connected to the connecting seat 401, so that the guard plate 402 and the connecting rod 403 can be easily repaired and replaced after being damaged.

[0065] The handrail 404 is disposed at the top of the connecting rod 403. The handrail 404 is disposed at the highest position of the connecting rod 403. The height of the handrail 404 should be suitable for a normal adult standing on the upper chassis 300 to grasp. The handrail 404 can be a round tube structure to improve the gripping feel. It should be noted that the cross-sectional shape of the handrail 404 is not limited to a circle, and those skilled in the art can design it according to actual needs.

[0066] like Figure 4As shown, a reinforcing diagonal brace 113 is provided between the column assembly and the lower chassis 200. The upper intermediate chassis 302 and the upper cross beam 108 can be welded, the column assembly and the diagonal brace assembly and the side beam 201 can also be welded, and the reinforcing diagonal brace 113 can be welded between the column assembly and the lower chassis 200. Such a design enables the vehicle body side wall 100, the upper intermediate chassis 302 and the lower chassis 200 to form a stable box-type structure, meeting the vehicle body rigidity and strength requirements.

[0067] like Figure 6 As shown, downwardly extending connecting beams 3011 are arranged on both sides of the upper end chassis 301, and the steel wire rope 601 of the lifting auxiliary device 600 is connected to the connecting beams 3011 to assist in pulling the upper end chassis 301 to perform lifting and deflecting actions.

[0068] like Figure 1 As shown, the ends of the upper end chassis 301 and the two ends of the lower chassis 200 are both provided with a ferry 700. The setting height of the ferry 700 can be consistent with the existing railway double-deck transportation vehicle, so that the existing vehicle model can be connected and rolled on and off.

[0069] The embodiment of the present invention also discloses a special vehicle for railway double-deck transport automobiles, which includes the railway freight car body disclosed in the above embodiment. Since it has the above railway freight car body, it has all the technical effects of the above railway freight car body, which will not be repeated herein.

[0070] In addition to the lightweight body side walls 100, the railway double-decker transport vehicle also adopts a lightweight upper chassis with improved structure (the ferry 700 on the upper end chassis 301 is a split structure, that is, the ferry 700 is only arranged at the wheel position), a lightweight lifting auxiliary device 600 (for example, a spring balancer can be used, which can save the counterweight and reduce the weight of the lifting auxiliary device 600). The weight of the entire vehicle is reduced by 10% compared with the SQ6 model, which reduces traction energy consumption and reduces vehicle traction costs.
