The invention discloses a rolling device for railway roadbed construction filler, and relates to the technical field of soil compaction. The rolling device for the railway roadbed construction filler comprises a device main body, the device main body comprises a vehicle body, a mounting frame connected with the vehicle body and a grinding roller connected with the mounting frame; the device main body further comprises two groups of auxiliary rolling mechanisms for rolling the edge and the side slope of the roadbed. According to the rolling device for the railway roadbed construction filler, the roadbed edge and the side slope are recognized through the recognition mechanism, the auxiliary rolling wheel extends out through the adjusting mechanism and the rotating mechanism according to the recognition result, the inclination angle of the auxiliary rolling wheel is adjusted, the auxiliary rolling wheel makes contact with the roadbed edge or the side slope, and pressure is applied under the action of the pressure applying mechanism; according to the roadbed edge rolling device, rolling operation of a roadbed edge pre-pressing locking edge or a side slope is achieved, the roadbed edge rolling device is more convenient and faster, the filler can be prevented from sliding and collapsing towards the side slope, rolling blind areas can be avoided, and the rolling efficiency and quality are improved.

This application discloses a limiting mechanism and a welding strip substrate feeding device for feeding welding strip substrate. The limiting mechanism includes at least one limiting unit. The limiting unit abuts against the separation point of the welding strip substrate on the inner circumferential surface of the welding strip base material roll to limit the height of the pulled-out welding strip substrate from the separation point on the inner circumferential surface of the welding strip base material roll, thereby preventing the welding strip substrate on the inner ring of the welding strip base material roll from slipping. This application effectively avoids the problem of wire jamming during welding strip substrate feeding caused by the collapse of the inner ring of the welding strip base material roll, effectively preventing abnormal wire breakage of the welding strip substrate, thereby improving production efficiency and yield.
