Embodiment Construction
[0013] Multi-purpose rails, including two inner rails 6 arranged at the center of the bottom beam sleeper 4 with an inner edge spacing of 600mm wide, and two sliding guide rails at the same distance from the inner rails are arranged on both sides of the two inner rails 6 1. Both sides of the above-mentioned sliding guide rail 1 are respectively fixed on the bottom beam sleeper 4 through the rail weight 5 and the rail limit block 2, and the above-mentioned two sliding-guiding rails 1 are higher than the above-mentioned two inner rails 6. The length of the bottom beam sleeper 4 is 1.8m, the distance between the inner edges of the two sliding guide rails 1 is 1500mm, and the two sliding guide rails 1 are 40mm higher than the above two inner rails.
[0014] work process:
[0015] The multipurpose rail uses 12 # Mine I-beams are used as bottom beam sleepers (track slabs), the length of the bottom beam is 1.8m, and 22kg / m steel rails are used as sliding and transport rails. The int...

The invention provides a multipurpose rail and belongs to a rail technology in the technical field of rail conveying and mine transportation. According to the technical scheme provided by the invention, the multipurpose rail comprises two inner rails which are arranged in the center of a bottom beam sleeper, and the distance between the inner edges of the two inner rails is 600mm; the multipurpose rail is characterized in that two slippage guide rails which have the same distance from the inner rails are arranged on the two sides of the two inner rails respectively; the two sides of each of the slippage guide rails are fixed on the bottom beam sleeper by rail press iron and rail limiting blocks respectively; the two slippage guide rails are higher than the two inner rails. The multipurpose rail has the advantages that the inner rails located in the middle are directly used as operation rails of a flat car or a tramcar to convey equipment or materials at ordinary times. When the height of the working surface is low, the inner rails in the middle can be used for directly bearing the weight of the bracket equipment during the process of dragging a bracket or large-size equipment, and the friction resistance between the bracket and a bottom plate is reduced; the rails on the two sides have the limiting effect so that a deviation phenomenon can be avoided during the dragging process of the equipment including the bracket and the like.
Description
[0001] Technical field: [0002] The patent relates to a multipurpose rail, which belongs to rail technology in the technical fields of rail transportation and mine transportation. [0003] Background technique: [0004] During the removal process of the fully mechanized mining face in the coal mine, the working face is limited by the geological conditions and the characteristics of the transportation equipment itself. The height of the mine site often cannot meet the loading and transportation requirements of the equipment, and the whole piece can only be towed along the floor. Because the hauling equipment is relatively heavy, it is very difficult to haul along the bottom plate, resulting in uneven bottom plate damage, winch broken rope, winch overload damage, equipment rollover, support material loss and scraping support and other safety accidents. Personnel reciprocating to and from the support pulling area brings different degrees of threats to personal safety and equip...
