[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] To achieve the above-mentioned utility model objectives, as shown in Figures 1-4, this utility model provides a rail transport trolley in a limited space, including an adjustable I-beam groove 1 and rollers 2. The rollers 2 are rotatably installed on both sides of the adjustable I-beam groove 1, and the threaded steel 7 is fixedly installed on one side of the upper end of the adjustable I-beam groove 1. A track 6 is placed on the upper end of the adjustable I-beam groove 1.

[0035] In this embodiment, when using the rail transport trolley, two people lift one end of the rail 6 off the ground to form a certain angle. The operator pushes the trolley to the center of the rail, and then places the rail 6 on the adjustable I-beam groove 1 of the trolley. Using the lever principle, the rail is lifted, and the operator transports the rail to the designated position. The trolley is tilted so that one end of the rail 6 contacts the ground, and the assistant slightly lifts the rail 6 to detach the trolley from under the rail. The rail is then placed on the ground, and the position of the rail can be adjusted to ensure it is on the correct travel route, thus completing the transport of the rail in a limited space.

[0036] As shown in Figure 3, a roller protection plate 3 is welded to the upper outer side of the adjustable I-beam groove 1. A roller gasket 4 is welded to the lower end of the roller protection plate 3 on the side away from the adjustable I-beam groove 1. The adjustable I-beam groove 1, the roller protection plate 3, and the roller gasket 4 form the rotating chamber of the roller 2. The roller 2 rotates inside the rotating chamber by screws 5. There are two rollers 2 in total, and the two rollers 2 are respectively rotatably installed on the left and right sides of the adjustable I-beam groove 1. In this way, the rotation of the rollers 2 can realize the transportation of the track 6.

[0037] As shown in Figure 4, the adjustable I-beam groove 1 includes a fixed frame 8 and a telescopic plate 10. The telescopic plate 10 is inserted into the inner side of the two fixed frames 8. The fastening screw 9 is screwed into the lower end of the fixed frame 8. The inside of the fixed frame 8 is provided with a groove corresponding to the telescopic plate 10. The telescopic plate 10 is inserted into the groove of the fixed frame 8. The bottom of the fixed frame 8 is provided with a threaded hole. The fastening screw 9 is screwed into the threaded hole. Its top can abut against the telescopic plate 10, thereby locking the relative position of the fixed frame 8 and the telescopic plate 10.

[0038] In this embodiment, by adjusting the relative positions of the fixing frame 8 and the telescopic plate 10, and then locking them with the fastening screws 9, the internal width of the adjustable I-beam groove 1 can be adjusted, thereby enabling the transportation and handling of tracks 6 of different widths.

[0039] Preferably, the threaded steel bar 7 and the adjustable I-beam groove 1 are fixedly connected by welding, and the threaded steel bar 7 is set at 30° with the horizontal plane. In this way, the threaded steel bar 7 can be used to push the rail transport trolley, making it more convenient for the rail transport trolley to transport the rail 6.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
