Aiming at different track forms and working conditions, the laying type mode of the railway track presents the diversity.

The rail laying operation refers to a construction process of laying rail materials such as steel rails, sleepers, turnouts and the like on specified positions of a line in a certain mode according to construction technical standards after a roadbed is renovated. The rail laying mode comprises two modes of manpower and machinery, wherein the rail laying mode comprises the steps of firstly conveying rail materials to a rail laying site and then manually laying the rail materials. The mechanical track laying is that firstly the track panel nailed and connected at the track panel base is transported to the front of the track laying, and then the track panel is laid on the roadbed by the track laying machine and connected section by section. And the mechanical rail laying operation also comprises the laying of long steel rails, namely, the factory-made long steel rails with the length of 250-500 m are laid on the repaired line, and then the on-site welding and locking are carried out to form a seamless line.

Before laying the steel rail, a plurality of rollers are required to be sequentially placed on the roadbed along the length direction of the rail, one end of one steel rail is dragged to drag the steel rail along the rollers, and after the steel rail is dragged in place, the rollers are collected away, so that the steel rail is laid on the roadbed.

In the prior art, the multiple rollers are generally placed and taken up manually, which is time-consuming and labor-consuming in the whole rail laying process.

Through searching, the patent documents which are the same as or similar to the patent documents in the application are not discovered for a while.
