[0032] In order to better understand the purpose, function and specific design of the present invention, the motorized railway loading and unloading platform vehicle of the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] As Figures 1-14 shown, the motorized railway loading and unloading platform vehicle of the present invention includes a railway flatcar body 1. The flatcar body 1 is used to move and transport vehicles or materials on the railway. A support assembly 2 is movably arranged on the side of the flatcar body 1. The support assembly 2 can rotate relative to the flatcar body 1 so that the support assembly 2 is in a retracted state or a supported state. When in the retracted state, the support assembly 2 can move with the flatcar body 1; when in the supported state, the lower part of the support assembly 2 abuts against the ground, and the upper part of the support assembly 2 can carry items.

[0034] A loading and unloading platform 11 is arranged above the flatcar body 1. A folding platform 3 is movably arranged on the loading and unloading platform 11; the folding platform 3 can be moved onto the support assembly 2 in the supported state. Preferably, there are multiple groups of support assemblies 2, and each group of support assemblies 2 can rotate relative to the flatcar body 1 so that the support assembly 2 is in a retracted state or a supported state. Multiple groups of support assemblies 2 can improve the stability when supporting the folding platform 3. In this embodiment, there are 4 groups.

[0035] The folding platform 3 includes a main platform 31 and a folding ramp 32. The two sides of the main platform 31 are respectively hinged to a folding ramp 32. The folding ramp 32 can rotate relative to the main platform 31 so that one end of the folding ramp 32 abuts against the ground and the other end is connected to the main platform 31. The vehicle to be transported can move onto the main platform 31 through the folding ramp 32, then the folding ramp 32 is flipped and reset, and then the folding platform 3 is moved onto the loading and unloading platform 11 to complete the loading of the vehicle.

[0036] Specifically, as Figure 4As shown, a ball screw assembly 4 is fixedly arranged on the loading and unloading platform 11. The ball screw assembly 4 is connected to the bottom of the folding platform 3 to drive the folding platform 3 to move on the loading and unloading platform 11. The ball screw assembly 4 includes a driving motor 41. The driving motor 41 is connected to a lead screw 42. A slide table 43 is arranged on the lead screw 42. The rotation of the lead screw 42 can drive the slide table 43 to move. The slide table 43 is fixedly connected to the main platform 31 to drive the main platform 31 to move.

[0037] As Figure 6 and Figure 8 shown, a first flipping assembly 5 is arranged on the main platform 31. The first flipping assembly 5 is connected to the folding ramp 32. The first flipping assembly 5 can drive the folding ramp 32 to rotate. The first flipping assembly 5 includes a first oil cylinder 51, a first flipping arm 52, and a second flipping arm 53. A first groove 311 is arranged on the main platform 31. The bottom of the first oil cylinder 51 is hinged to a position at the end of the first groove 311 away from the main platform 31. One end of the first flipping arm 52 is hinged to a position at the end of the first groove 311 close to the main platform 31. The other end of the first flipping arm 52 is hinged to the output shaft of the first oil cylinder 51; a second groove 321 is arranged on the folding ramp 32. One end of the second flipping arm 53 is hinged to a position at the end of the second groove 321 close to the folding ramp 32. The other end of the second flipping arm 53 is hinged to the output shaft of the first oil cylinder 51. When the output shaft of the first oil cylinder 51 extends, the folding ramp 32 can be rotated in a direction away from the main platform 31. When the output shaft of the first oil cylinder 51 contracts, the folding ramp 32 can be rotated in a direction close to the main platform 31 until the folding ramp 32 fits against the main platform 31. It can be understood that, as Figure 8 and Figure 9 shown, the first flipping assembly 5 can be arranged on both sides of the folding ramp 32 or at the middle position of the folding ramp 32. The specific position is selected and designed according to actual needs, as long as it can enable the folding ramp 32 to rotate relative to the main platform 31 and does not affect the vehicle driving on the ramp.

[0038] Preferably, as Figure 10 shown, the folding ramp 32 of this embodiment includes a first folding ramp 33 and a second folding ramp 34. The first folding ramp 33 is hinged to the second folding ramp 34. The first folding ramp 33 is connected to the main platform 31. The second folding ramp 34 can abut against the ground. The hinged first folding ramp 33 and second folding ramp 34 can save the storage space of the folding ramp 32, and by changing the angle between the first folding ramp 33 and the second folding ramp 34, different ground heights can be adapted to enhance the versatility of the present invention. Preferably, one end of the second folding ramp 34 away from the first folding ramp 33 is connected to a guide block 35. The guide block 35 is hinged to the second folding ramp 34. The bottom surface of the guide block 35 abuts against the ground.

[0039] As Figure 7 shown, a second flipping assembly 6 is provided on the first folding ramp 33. The second flipping assembly 6 is connected to the second folding ramp 34, and the second flipping assembly 6 can drive the second folding ramp 34 to rotate. The second flipping assembly 6 includes a second oil cylinder 61, a third flipping arm 62, and a fourth flipping arm 63. A third groove 331 is provided on the first folding ramp 33. The bottom of the second oil cylinder 61 is hinged to a position of the third groove 331 away from the second folding ramp 34. One end of the third flipping arm 62 is hinged to a position of the third groove 331 close to the second folding ramp 34. The other end of the third flipping arm 62 is hinged to the output shaft of the second oil cylinder 61. A fourth groove 341 is provided on the second folding ramp 34. One end of the fourth flipping arm 63 is hinged to a position of the fourth groove 341 close to the first folding ramp 33. The other end of the fourth flipping arm 63 is hinged to the output shaft of the second oil cylinder 61. When the output shaft of the second oil cylinder 61 extends, the second folding ramp 34 can be rotated away from the main platform 31. When the output shaft of the second oil cylinder 61 contracts, the second folding ramp 34 can be rotated towards the first folding ramp 33 until the first folding ramp 33 fits with the second folding ramp 34.

[0040] As shown in Figure 3, a support receiving groove 12 is provided on the side of the flat car body 1. A rotary oil cylinder 13 is provided in the support receiving groove 12. The rotary oil cylinder 13 is connected to one end of the support assembly 2, and the rotary oil cylinder 13 can drive the support assembly 2 to rotate relative to the flat car body 1. When the support assembly 2 is accommodated in the support receiving groove 12, it is in the storage state, and the support assembly 2 can be transported together with the flat car body 1.

[0041] The support assembly 2 includes a support arm 21. One end of the support arm 21 is connected to the rotary oil cylinder 13, and the rotary oil cylinder 13 can drive the support arm 21 to rotate. A plurality of support oil cylinders 22 are fixedly provided below the support arm 21. One end of each support oil cylinder 22 away from the support arm 21 is connected to a floor footing 23. When the output shaft of the support oil cylinder 22 extends, the floor footing 23 can be brought into contact with the ground to achieve the support state of the support assembly 2.

[0042] Preferably, rollers 24 are provided on the upper surface of the support arm 21. Correspondingly, roller grooves 312 are provided on the lower surface of the main platform 31. The rollers 24 can be accommodated in the roller grooves 312. On the one hand, it is convenient for the folding platform 3 to move from the loading and unloading platform 11 to the support assembly 2. On the other hand, through the cooperation of the rollers 24 and the roller grooves 312, the main platform 31 can also be limited in position to improve the stability when the vehicle being transported gets on and off the folding platform 3.

[0043] The mobile railway loading and unloading platform vehicle of the present invention further includes a control box, in which a control system is provided. The control system is electrically connected to the controllers of the rotary oil cylinder 13, the support oil cylinder 22, the drive motor 41, the first oil cylinder 51 and the second oil cylinder 61. Each component performing an action is controlled by different switch buttons in the control box.

[0044] When the mobile railway loading and unloading platform vehicle of the present invention is loading, first, the rotary oil cylinder 13 drives the support assembly 2 to rotate, making the support assembly 2 perpendicular to the flat car body 1. Then, the support oil cylinder 22 extends, making the ground feet 23 touch the ground, and the support assembly 2 is in a supporting state. Then, the ball screw assembly 4 drives the folding platform 3 to move onto the support assembly 2. Subsequently, the first flipping assembly 5 drives the folding ramp 32 to rotate away from the main platform 31, and at the same time, the second drive assembly drives the second folding ramp 34 to rotate away from the first folding ramp 33 until the guide block 35 at the end of the second folding ramp 34 touches the ground, which means the unfolding is completed. Then, the vehicle to be transported travels onto the main platform 31 through the folding ramp 32. Then, the second flipping assembly 6 drives the second folding ramp 34 to rotate and makes the first folding ramp 33 lift upward, and at the same time, the first flipping assembly 5 drives the first folding ramp to rotate. Then, the first folding ramp 33 and the second folding ramp 34 gradually rotate back to their original positions. After that, the ball screw assembly 4 drives the folding platform 3 to move onto the loading and unloading platform 11. As Figure 12 shown, finally, the support oil cylinder 22 contracts, the ground feet 23 leave the ground, and the rotary oil cylinder 13 drives the support assembly 2 to rotate into the support storage groove, which means the loading of the vehicle is completed. At this time, the mobile railway loading and unloading platform vehicle of the present invention can transport the vehicle to be transported. As Figures 13-14 shown, the flat car body of the mobile railway loading and unloading platform vehicle of the present invention can also be connected to multiple flat car platforms. Then, the flipping folding ramp 32 is lapped on other flat car platforms, and the vehicle can be transported onto other flat car platforms. Then, the folding ramp 32 returns to its original position. Thus, a train of flat cars can transport multiple vehicles at the same time. If the vehicle needs to be unloaded, just reverse the above steps, which will not be elaborated here.

[0045] The structure of the mobile railway loading and unloading platform vehicle of the present invention is ingeniously designed. It uses a movable folding platform to load and unload the vehicle to be transported, and can complete the loading and unloading of the vehicle without relying on a traditional platform, and can perform loading and unloading at any location, improving the flexibility of loading and unloading, and effectively solving the requirements for transportation timeliness and flexibility in aspects such as emergency rescue, disaster relief, national defense, and the national economy.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
