[0023] The present utility model will be further described below with reference to the accompanying drawings.

[0024] When a rail flat car loads different rail freight cars, generally, it is necessary to position and reinforce the loaded rail freight cars by using a loading tooling so that the loaded rail freight cars can be more stable. In the related art, the center plate and side bearings of the loaded rail freight cars are supported and positioned. However, since the lengths of different rail freight cars are different, the center distance between the two center plates of the rail freight cars is different. Therefore, different loading toolings are required for positioning, wasting a large amount of tooling materials and the like, and the loading efficiency is low.

[0025] The present utility model provides a support device for a rail flat car and a rail flat car, which can support and position the loaded rail freight cars, save loading and reinforcement materials, shorten the loading time of the rail freight cars, and improve the loading efficiency.

[0026] Figure 1 is a schematic structural view of a support device of a rail flat car from a perspective in an embodiment of the present utility model; Figure 2 is a schematic structural view of parts of a support assembly of a support device of a rail flat car in an embodiment of the present utility model with some parts omitted. As Figures 1-2As shown in the figure, an embodiment of the present application provides a support device 100, and the support device 100 includes a support assembly 10 and a drive assembly 20. The support assembly 10 includes a first support beam 11 extending along a first direction X. The first support beam 11 is used to support the center plate and side bearing of the loaded rail vehicle. The drive assembly 20 is drivingly connected to the first support beam 11. The drive assembly 20 is capable of driving the first support beam 11 to move along a second direction Y. The first direction X is perpendicular to the second direction Y.

[0027] It should be noted that when the support device 100 is in use, the second direction Y is parallel to the length direction of the loaded vehicle, and the first direction X is parallel to the width direction of the vehicle.

[0028] It can be understood that the drive assembly 20 can be a telescopic member capable of driving the first support beam 11 to move along the second direction Y, or a gear-rack assembly or an electric servo module driven by a drive member, etc. When the drive assembly 20 is a drive member and a gear-rack, gears can be rotatably provided at both ends of the first support beam 11 along the first direction X and racks engaged with the gears. The drive member drives the gears to rotate, so that the gears move along the second direction Y on the racks, and further the first support beam 11 can move in the first direction X. Of course, the drive assembly 20 can also be other components that can drive the first support beam 11 to move, and no specific limitation is made in this embodiment.

[0029] According to the support device 100 of the embodiment of the present application, the first support beam 11 can support and position the center plate and side bearing of the loaded rail vehicle to position and reinforce the loaded rail vehicle. Since the vehicle lengths of different rail vehicles are different, the vehicle fixed gauge (the distance between the center plates of the vehicle) is different. The support device 100 is used in pairs when in use. The drive assembly 20 drives the first support beam 11 to move along the second direction Y, so that the distance between the two first support beams 11 in the second direction Y changes to adapt to the rail vehicles with different vehicle fixed gauges to be loaded, so that there is no need to replace different positioning loading tools when loading rail vehicles with different vehicle fixed gauges, thereby saving loading and reinforcement materials, shortening the loading time of rail vehicles, and improving the loading efficiency.

[0030] As Figure 1 As shown in the figure, in some embodiments, the first support beam 11 includes a support surface and a connection surface that are perpendicular to each other. The drive assembly 20 includes a pushing member 21. The pushing member 21 is drivingly connected to the connection surface to drive the first support beam 11 to move in the second direction Y.

[0031] In this embodiment, the pushing member 21 applies a pushing force or a pulling force in the second direction Y to the connecting surface of the first support beam 11 to drive the first support beam 11 to move in the second direction Y. When it is necessary to adjust the distance between the first support beams 11, the pushing member 21 drives the first support beam 11 to move in the second direction Y, so that the support position of the first support beam 11 changes to adapt to the loaded rail freight car.

[0032] As Figure 1 shown, in some embodiments, the pushing member 21 includes one of a hydraulic telescopic cylinder, a pneumatic telescopic cylinder, and an electric telescopic rod. In this embodiment, a hydraulic telescopic cylinder or a pneumatic telescopic cylinder is preferably used because the telescopic cylinder has the advantages of being able to bear a large load, being able to perform telescopic movement smoothly, having a compact structure, and occupying a small space.

[0033] As Figure 1 shown, in some embodiments, the support assembly 10 further includes a pair of second support beams 15 arranged in pairs. The pair of second support beams 15 arranged in pairs both extend in the second direction Y, and the pair of second support beams 15 arranged in pairs are spaced apart in the first direction X. The first support cross beam is movably connected to the pair of second support beams 15 arranged in pairs and can move relative to the pair of second support beams 15 arranged in pairs in the second direction Y.

[0034] In this embodiment, both ends of the first support beam 11 in the first direction X are slidably connected to the pair of second support beams 15 arranged in pairs through a slide rail and chute fit or are rotatably connected through a rolling bearing, so that the first support beam 11 can move relative to the second support beam 15 along the second direction Y relative to the pair of second support beams 15 arranged in pairs. The pair of second support beams 15 arranged in pairs play a guiding role for the first support beam 11 in the second direction Y, so that the first support beam 11 can move smoothly in the second direction Y, ensuring the stability and reliability of the first support beam 11.

[0035] As Figure 1 shown, in some embodiments, the support assembly 10 further includes a plurality of rollers 16, and the plurality of rollers 16 are installed at the bottom of the first support beam 11. The plurality of rollers 16 are connected to the first support beam 11 through connecting pins, so that the first support beam 11 can move easily on the track flat car where the rail freight car needs to be loaded, improving the mobility, stability, and load-bearing capacity of the first support beam 11.

[0036] As Figure 2 shown, in some embodiments, the support assembly 10 further includes a first side bearing support member 12, a center plate support member 13, and a second side bearing support member 14 that are sequentially spaced apart in the first direction X. The first side bearing support member 12, the center plate support member 13, and the second side bearing support member 14 are all arranged on the connecting surface.

[0037] In this embodiment, a first side bearing support member 12, a center plate support member 13, and a second side bearing support member 14 are sequentially and spaced apart along a first direction X on the support surface of the first support beam 11. Among them, the center plate support member 13 is used to support the center plate of the loaded rail freight car and bear the main load; the first side bearing support member 12 and the second side bearing support member 14 respectively perform auxiliary support on the side bearings on both sides of the center plate of the loaded rail freight car to ensure stable and uniform force on both sides during the loading process of the rail freight car.

[0038] As Figure 2 shown, in some embodiments, the center plate support member 13 includes a support seat 13a and a support disc 13b. The support seat 13a is installed on the support surface, and the support disc 13b is detachably connected to the support seat 13a. The support disc 13b is used to cooperate with the center plate.

[0039] In this embodiment, the center plate support member 13 is fixed to the support surface through the support seat 13a, while the support disc 13b is in close fit with the center plate. The support seat 13a is the basic part of the center plate support member 13. It is installed on the support surface to provide stable support for the entire support member. The support seat 13a is usually firmly connected to the connection surface by bolts, welding, or other fastening methods to ensure that it will not loosen or displace when bearing the load. The support disc 13b is detachably connected to the support seat 13a, making the maintenance and replacement of the support disc 13b more convenient, reducing the maintenance cost and time.

[0040] As Figure 2 shown, in some embodiments, both the first side bearing support member 12 and the second side bearing support member 14 are telescopic members that can be telescoped along a third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other in pairs.

[0041] In this embodiment, since both the first side bearing support member 12 and the second side bearing support member 14 are telescopic members that can be telescoped along the third direction Z, the first side bearing support member 12 and the second side bearing support member 14 can flexibly change their support lengths in the third direction Z to adjust the uniform force on the side bearings on both sides of the center plate of the loaded rail freight car and improve the loading stability of the rail freight car.

[0042] As Figure 2 shown, in some embodiments, the two telescopic members are oil cylinders. The oil inlets of the two oil cylinders are connected to each other, and the oil outlets of the two oil cylinders are connected to each other, so that the driving forces of the two oil cylinders are the same to ensure the synchronous operation of each oil cylinder.

[0043] In this embodiment, both the first side bearing support member 12 and the second side bearing support member 14 are oil cylinders. The two oil cylinders can be telescoped simultaneously to avoid uneven force on the side bearings on both sides of the loaded rail freight car caused by different telescopic lengths, ensuring the loading stability of the rail freight car.

[0044] The embodiment of the present application further provides a rail flat car, including the support device 100 in any of the foregoing embodiments. Since the rail flat car provided by the embodiment of the present application has the support device 100 in any of the above embodiments, this rail flat car has all the beneficial effects of the above support device 100, which will not be elaborated herein one by one.

[0045] Although the present utility model has been described with reference to the preferred embodiments, various improvements can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any manner.
