Abstract: In view of the special environment of non-standard track laying in the underground excavated roadway, large horizontal height difference between the front and back and the left and right of two load-bearing tracks, and the condition that the dust-removing equipment running synchronously on the tracks is liable to fall off the track and overturn, threatening the personal safety of miners, an anti-derailment load-bearing vehicle for excavation roadway is designed. The load-bearing vehicle allows the front and rear height difference of the two carrying rails of the machine plane to be ≤100 mm, and the four wheel sets of the carrying vehicle can be kept in close contact with the track during operation, thereby ensuring that the load-bearing vehicle never goes down. The load-bearing vehicle has the advantages of convenient installation, small maintenance, low failure rate, no requirement for laying roadway of the roadway.
