[0030] Preferably, there are many options for the power unit, including electric, pneumatic, and hydraulic. Electric can use a motor, and pneumatic can use a cylinder, but it is not very suitable for railway scenes. The main reason is that electric and pneumatic require electricity or gas as a power source. To obtain these power sources, it is necessary to manually bring power sources such as generators and air compressors to the site, preferably hydraulic tools such as cylinders or jacks. The rail car 1 also includes a mounting seat 16, and the power unit 14 is arranged on the mounting seat 16. The mounting seat 16 is movable through the rotating shaft and the support frame 12. dynamic connection; the power unit 14 can make a fan-shaped movement with the rotating shaft as the axis to cooperate with the arc-shaped rising and falling movements of the grabbing part 13; it should be noted that when lifting and putting down the rails to be transported, the movement should be slow, which can reduce the probability of equipment damage and accidental falling of the rails to be transported; the cylinder and the jack can both meet this requirement; in addition, the cylinder and the jack both have a locking function, that is, after the rails to be transported are lifted into place, they are stuck to prevent the height of the rails to be transported from slowly decreasing due to the gravity of the rails to be transported and slowly pressing down until they are close to the ground.

[0031] Preferably, the gripping portion 13 includes a left plate 131, a right plate 132, a first rotating shaft 133, a second rotating shaft 134 and a first pin 135, the left plate 131 and the right plate 132 are arranged at a predetermined distance, the left plate 131 and the right plate 132 are respectively provided with three corresponding through holes, the first rotating shaft 133, the second rotating shaft 134 and the first pin 135 are respectively inserted into one through hole; the output shaft of the power unit 14 is transmission-connected to the first pin 135; it can be understood that the two ends of the rail are provided with A through hole for connecting rails to rails, wherein the first rotating shaft 133 and the second rotating shaft 134 can be an axially through structure. With such a design, the first rotating shaft 133 and / or the second rotating shaft 134 can be directly used to grab the rail to be transported, or a bare rod can be inserted into the first rotating shaft 133 and / or the second rotating shaft 134 to grab the rail to be transported. The first rotating shaft 133 and / or the second rotating shaft 134 is used to grab the rail to be transported, and the first rotating shaft 133 and / or the second rotating shaft 134 is used to insert the first rotating shaft 133 and / or the second rotating shaft 134 into the through hole on the rail to be transported.

[0032] Preferably, the grabbing portion 13 further includes a reinforcing plate 136 , which is disposed between the left plate 131 and the right plate 132 , and is used to reinforce the connection between the left plate 131 and the right plate 132 .

[0033] Preferably, the cross-section of the left plate 131 is triangular, and the right plate 132 is the same as the left plate 131, and three through holes are respectively arranged at the corners of the triangle; the triangle has the advantage of structural stability, and is more stable when the power unit 14 drives the grabbing part 13 to move through the first pin 135.

[0034] Preferably, the length of the first rotating shaft 133 is greater than the distance between the left plate 131 and the right plate 132, and both ends of the first rotating shaft 133 protrude out of the left plate 131 and the right plate 132. The structure of the second rotating shaft 134 is the same as that of the first rotating shaft 133. The parts of the first rotating shaft 133 protruding out of the left plate 131 and the right plate 132 can respectively lift a railway track. That is to say, two railway tracks to be transported can be transported simultaneously by this device. When only one railway track to be transported is transported, it can also be operated in this way. However, it will cause greater pressure on one side of this device, making it difficult for workers to push and easily damaging this device. Therefore, when only one railway track to be transported is transported, the first rotating shaft 133 or / and the second rotating shaft 134 can be pulled out, the railway track to be transported can be placed between the left plate 131 and the right plate 132, and then the first rotating shaft 133 or / and the second rotating shaft 134 can be inserted, so as to ensure balance.

[0035] Preferably, the rail car 1 is provided with a connection hole 17. The connection hole 17 has two uses. The first use is that when pushing the car, a crowbar or other rod-shaped tool is inserted into the connection hole 17 to facilitate pushing the car without the need for workers to bend down to push. The second use is that when the car is empty, if one rail car 1 is pushed by one person, under the action of gravity, the grasping part 13 may drag on the ground and is easily damaged, and it can only be carried by workers. Therefore, through the connecting rod 2, two rail cars 1 are connected into a four-wheel car to facilitate pushing, and some tools can also be placed on the four-wheel car and just push the four-wheel car away. It can be understood that one connection hole 17 or multiple connection holes 17 can be provided on each rail car 1.

[0036] Preferably, it further includes a connecting rod 2. Both ends of the connecting rod 2 are respectively inserted into the connection holes 17 on one rail car 1 to fix the distance between the two rail cars 1.

[0037] Preferably, the roller 15 is made of insulating material, which can prevent static electricity generated by the friction between the roller 15 and the railway.

[0038] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solution and the inventive concept of the present invention, and all such changes or substitutions should fall within the protection scope of the claims attached to the present invention.
