Description

Technical Field

[0001] The utility model relates to the technical field of rail welding conveying rollers, in particular to an insulating rail welding conveying roller. Background Art

[0002] Rail welding is an important part of railway track construction. It ensures the continuity and integrity of the rails and is crucial to improving the safety and stability of railway transportation.

[0003] In order to move the rails smoothly, it is generally necessary to lay a rail conveyor line, which is generally composed of multiple rail conveyor brackets. The rail conveyor brackets include brackets and rollers. The rollers are a main device on the rail conveyor line for supporting the rails, transmitting power to make the rails move horizontally, and preventing the rails from running off the track during movement.

[0004] At the same time, according to the railway's requirements for rail welding, during the rail welding process, the rail welding machine needs to be insulated from the power grid and the ground to avoid welding current shunting, which will lead to unstable welding joint performance, reduced welding quality, and even damage to the rail base material.

[0005] In order to ensure the stability of welding process and improve welding quality, the traditional solution is to lay engineering insulation materials under the rail conveying support of the conveying rail, but the effect is not very ideal;

[0006] The reason is that the insulating materials of the paving project cannot completely insulate the rails from the ground. The rail conveying bracket is connected and fixed by connecting bolts, and there are still uninsulated positions. In addition, the paving project insulating materials are laid over a large area and the cost is high. Utility Model Content
