[0002] When transporting large items, they are often transported by train or train carriages, while the transportation of cars is considered large items, and trains are usually used for batch transportation to save costs;

[0003] Traditionally, cars are often hoisted when being moved to or from trains, and the position angle of the car needs to be ensured during hoisting to facilitate transportation; however, when cars are getting on and off trains, the gap between the train carriage and the platform and the limitation of the train's front end may cause operational inconveniences in car transportation. In order to maximize the cost of train transportation, it is often necessary for trains to unload a batch of cars and then reload a new batch of cars at the same location. Traditional platforms can only complete single tasks, thus wasting the work efficiency of train loading and unloading. Therefore, a train platform is needed to facilitate the transportation of cars to train carriages for transportation work.

[0004] In view of the above problems, a platform mechanism is proposed for facilitating cars to get on and off trains. Summary of the invention

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention provides a platform mechanism for facilitating cars getting on and off trains. The wheels make the disc contact with the track to maintain its basic movement function. The first motor drives the gear to rotate and mesh with the crescent gear, so that the disc can rotate at a certain angle. Due to the design of the bearing, the rotation is smoother and the force on the disc is more even.

An inner ring 702 is fixedly connected to the middle of the upper surface of the chassis 1, and an outer ring 701 is fixedly connected to the middle of the lower surface of the vehicle disc 3. The first motor 501 is fixedly connected to both diagonally opposite sides of the upper surface of the chassis 1. The diagonally opposite first motor 501 realizes that the subsequent rotation angle of the rack 503 is 45 degrees. The output shaft of the first motor 501 is fixedly connected to the first gear 502. Both sides of the lower surface of the vehicle disc 3 are fixedly connected to the rack 503. The first gear 502 is meshed with the rack 503. The outer wall of the vehicle disc 3 is integrally formed with a slope plate 18, and the slope plate 18 facilitates the vehicle to enter the vehicle disc 3.

[0024] When reaching the designated position, the first motor 501 drives the first gear 502 to rotate and mesh with the rack 503, so that the wheel disc 3 can rotate at an angle. Due to the outer ring 701 and the inner ring 702 in the bearing 7, the rotation of the wheel disc 3 is more lubricated, and the first motor 501 is prevented from being damaged due to excessive force, thereby increasing the function of long-term use.

[0025] Combination Figure 4 and Figure 5 A positioning groove 8 is provided on the lower surface of the vehicle disc 3, a telescopic rod 9 is fixedly connected inside the positioning groove 8, a second motor 10 is fixedly connected inside the output shaft of the telescopic rod 9, a bolt 11 is fixedly connected to the output shaft of the second motor 10, a screw hole 12 is provided on the upper surface of the platform 4, the bolt 11 is matched with the screw hole 12, the second motor 10 drives the bolt 11 to rotate, and the bolt 11 contacts the screw hole 12, due to the thrust of the telescopic rod 9, the bolt 11 is automatically threaded into the screw hole 12, realizing the fixed limit function.

Due to the thrust of the telescopic rod 9, the bolt 11 is automatically threaded into the nut 16 to achieve a fixed limit function. When the specified position is reached, the bolt 11 and the nut 16 are loosened, and then the first motor 501 drives the first gear 502 to rotate and mesh with the rack 503, so that the undercarriage 3 can rotate at an angle. Due to the outer ring 701 and the inner ring 702 in the bearing 7, the rotation of the undercarriage 3 is more lubricated, and the damage caused by excessive force on the first motor 501 is avoided, thereby increasing the function of long-term use. After the rotation adjustment is completed, the second motor 10 drives the bolt 11 to rotate, and the bolt 11 contacts the screw hole 12.
