Description
Technical field
The invention belongs to railway technology field, be specifically related to a kind of detachable track travel cover plate.
Background technology
JIS plate is the prefabricated road bed board that Japan brought into use on the non-fragment orbit of the Shinkansen the eighties, be used in the Shinkansen, northern land of opening for 1997, after Qinhuangdao Shenyang Special Passenger Line Fu delegation of the Ministry of Railways in 2002 investigates, introduce China, be widely used among the various line construction of China's track traffic.Through improvement and the manufacture craft improvement of domestic Ge Jia research institution, produce multiple distortion at present.But its basic structure still has hollow framework road bed board two kinds of form of structure for solid slab and middle part, the bottom of both sides erection rail is continuous solid.
Combined frame road bed board as described in Chinese patent CN103243619A, conveniently the replacing of road bed board dismounting and bottom vibration isolator, has added jack machinism in middle part is hollow.In center portion, railway roadbed basis, can gutter be set along track direction of advance during use.
Ladder-type sleepers is another kind of longitudinal sleeper formula ballast bed structure, traditional sleeper laterally fixes rail to ensure gauge, and ladder-type sleepers be both sides rail lower position use steel concrete build at rail direction continuous print sleeper beam, and connection crossbeam is equidistantly set between the sleeper beam described in two, effectively improve tradition and have quarrel line track ride comfort, described crossbeam is metal tube or nonmetals pipe or tie-beam, to ensure transverse strength and the gauge of track plates.
Although reduce material usage for ballastless bed above-mentioned road bed board, and have feature that is cost-saving, lightweight, convenient transportation, because of the structure of its intermediate openings, foreign debris easily enters in ballast bed structure, blocking gutter; Rise and fall along track direction of advance height, add the walking difficulty of engineering maintainer; For the track of some special construction, as linear electric motors track, require continuous laying electromagnetic induction plate between two rails, road bed board or ladder-type sleepers intermediate openings is long then cannot supporting track, opening is too short, cannot complete dismounting and replacing task.Be uneven in the middle part of track in addition and be also not easy to maintenance personal's walking and emergency evacuation etc.
