A kind of subway track-laying machine
Technical field
The utility model relates to the subway process mechanism technical field of laying a railway track, and particularly relates to a kind of subway track-laying machine.
Background technology
In recent years, along with the fast development of path to urbanization, urban traffic blockage problem is day by day serious, therefore, subway, as an important component part of urban public transport, more and more receives people's concern, and the fast development of subway is to solve one of main path of urban traffic blockage problem.In Construction of Urban Rail Traffic process, the track engineering centre in civil works and equipment installation project on the duration arranges of mating formation, it is the tight rear operation of civil works, be again the tight front operation of other equipment installation projects, the impact that job schedule was installed, debugged to the progress that track is mated formation on follow-up equipment is huge.In each operation of track installing engineering construction, in tunnel, section of track laying and concreting are critical processes, also be most important, the most rambunctious ring of manufacturing schedule, as the equipment of this link most critical, the technical performance of subway track-laying machine plays vital effect to whole work flow smooth and easy.In subway tunnel, the form of railway roadbed mainly contains at present: the forms such as general solid concrete roabed, T-shaped sleeper railway roadbed, steel spring floating slab road bed alternately exist; Tunnel structure variation mainly contains: shield structure, the shape of a hoof, rectangle, platform, closed guard gate etc. alternately change, and for adapting to various tunnel structures and railway roadbed form, the structure of subway track-laying machine, span must be carried out corresponding variation could realize machine paving.Narrow space in tunnel, old-fashioned subway track-laying machine changes span and the unfavorable factor such as the dangerous factor of structure is many, operation is inconvenient, the activity duration is long in hole, once and subway track-laying machine is stopped using in hole, the flow process that whole track is mated formation will cause stagnation, cause the work holdup.In addition, also there is following several respects outstanding problem in current used subway track-laying machine: 1, become across difficulty, and complicated operation, risk is difficult to controlled; 2, become across necessary disassemblying structure, inefficiency; 3, become and do not change across the actual span of rear subway track-laying machine, only change subway track-laying machine left and right gauge, subway track-laying machine clear span is inadequate, when little curve construction, because the existence of curve offset amount easily causes flat car iron track-laying machine impenetrably, can not lift the section of track and concrete conveyance case on flatcar; 4, change across only changing gantry crane lateral dimension by gauge, longitudinal size (just) cannot be adjusted, and there is no good applicability in complicated condition location; 5, in work progress, often occur work plane transition situation, each transition all will be disintegrated gantry crane to assemble again, affects programming.
