As a further improvement of the utility model, the bottom of the slip-stopping ring is provided with a pair of reinforcing ribs, one end of each reinforcing rib is fixedly welded with the bottom of the slip-stopping ring, and the other end of each reinforcing rib is fixedly welded with the sliding shaft, so that the slip-stopping ring is effectively supported by the reinforcing ribs, and when a pipeline falls on the rolling bearing, the welded part of the slip-stopping ring and the sliding shaft is prevented from being damaged.

As a further improvement of the utility model, the bottom of the sleeve is provided with a bolt hole, and the bolt hole is matched with a fastening bolt, so that after the sleeve is inserted into the cross arm, the sleeve is screwed into the bolt hole through the fastening bolt, and the sleeve and the cross arm are tightly pressed, thereby preventing the sleeve from moving on the cross arm when the pipeline is dragged, and being convenient to disassemble and assemble.

As a further improvement of the utility model, the included angle between the sliding shaft and the sleeve is 40-60 degrees, and the rolling bearing can maintain a good sliding state with the pipeline while ensuring that the rolling bearing can completely bear the weight of the pipeline, so that the pipeline is smoothly dragged.

As a further improvement of the utility model, the sliding shaft is a steel bar with the diameter of 20mm or more, so that the sliding shaft can better bear the weight of the pipeline and is not easy to deform, the safe dragging of the pipeline is ensured, the manufacturing cost is low, and the manufacturing cost is effectively reduced.

As a further improvement of the utility model, two rolling bearings are arranged on each sliding shaft and are symmetrically arranged, so that the weight of the pipeline is borne by the two rolling bearings, the use safety can be improved, and the stress points on the sliding shafts are arranged at two positions, so that the stress uniformity of the sliding shafts can be further improved, and the risk of deformation of the sliding shafts is reduced.
