Description

Technical Field

[0001] The utility model relates to the technical field of railway construction, and more specifically, to a fixed rail short-distance sliding device. Background Art

[0002] In railway maintenance and construction, for some rails that need to be moved a short distance, the traditional method relies on manpower or monorail vehicles. Figure 1-2 As shown, the monorail vehicle mainly includes a handle a, a wheel b and an iron hook c. The wheel b and the iron hook c are respectively fixed at one end of the handle a and are respectively located on both sides of the handle a. When in use, the iron hook c is used to hook up the rail e to be moved, and the wheel b is placed on the existing rail f and rolled back and forth to achieve short-distance movement of the rail. In the actual operation process, due to the large dead weight of the rail, the operator must use the principle of leverage to lift the rail off the ground. At this time, the balance of the lever force must be mastered, which is not easy to master during use and is easy to deviate. The operation requires strong skills; on the other hand, since at least two monorail vehicles need to be operated at the same time, in this case, the commander and the operator need to have a high degree of tacit understanding, otherwise it will cause the rail to fall due to uneven force, which poses a safety hazard.

[0003] Therefore, it is urgent to design a fixed rail short-distance sliding device to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a fixed rail short-distance sliding device for the above-mentioned deficiencies in the prior art, which can move the rails conveniently and quickly and improve construction safety.

[0006] As a further improvement, a reinforcing rib is provided at the connection between the connecting plate and the supporting plate.

[0007] Furthermore, a reinforcing rod is provided between the two supporting plates on both sides of the roller.

[0008] Furthermore, the roller is a nylon insulating wheel.
