Description
Technical field
The utility model relates to a kind of high-speed railway when building 500m and following laying of welded long rails equipment especially relates to a kind of drawing to the ballastless track long steel rail of the track laying position tractor of laying a railway track on will long rail transport vehicle.
Background technology
The structure of ballastless track of high-speed railway is made up of bridge or roadbed, seat concrete or hydraulicity supporting layer, rail fastening on track slab system and rail etc., at first at the seat concrete or the hydraulicity supporting layer of bridge floor of having built or roadbed, and then laid rail guidance tape, the laying of track plate is accurately to adjust disposable up to standardly according to the line design key element, and then lays long rail on the track plate.Traditional ballasted track laying of welded long rails mainly adopts single pillow continuous laying method, the laying of batch (-type) list pillow, long rail to push and lay or change the shop method and carry out at home.These four kinds of paving modes having in the quarrel railway roadbed laying of welded long rails at home used more (Qinhuangdao Shenyang Special Passenger Line); Long rail pushes mainly will lack in factory after the rail welding growth rail, be transported on the existing line by four layers of transport vehicle, unloading the long rail car pusher propelling movement of rail place utilization rail, transport vehicle retreats simultaneously, long rail is unloaded the job practices on the curb that is put in the circuit both sides; Changing shop laying of welded long rails method mainly is at newly-built ew line a kind of laying of welded long rails method of carrying out on the quarrel railway roadbed to be arranged, at first be laid to the short rail track of 25m or 12.5m with track-laying machine, after whole road is up to standard, transport vehicle is transported to the job site with long rail then, unload on the curb that is put in the circuit both sides, utilize and manually will lack the rail dismounting, long rail is changed to a kind of laying method of circuit.These two kinds of methods are mainly used in the common laying construction method that quarrel railway roadbed railway is arranged.Single pillow continuous laying method, batch (-type) list pillow are laid on the long rail of the disposable laying of high-speed railway that is mainly used in the quarrel railway roadbed, and long rail is dragged long rail in the circuit both sides by caterpillar tractor, and the pillow that looses is then received a kind of paving mode of rail.These two kinds of job practicess are mainly used in single pillow method laying of welded long rails construction of quarrel railway roadbed.More than four kinds of methods can satisfy the construction needs having on the quarrel railway roadbed, but on non-fragment orbit, change the shop method owing to do not have rail on the track, track construction equipment can't arrive the job location and can't satisfy the construction needs.Single pillow or continuous laying and single pillow be laying method intermittently, all be to adopt caterpillar tractor to carry out laying of welded long rails, but on the track plate face of having laid on the no tiny fragments of stone, coal, etc. railway roadbed, caterpillar tractor can't traveling, causes railway roadbed to damage because caterpillar tractor walking on no tiny fragments of stone, coal, etc. railway roadbed can damage the track plate.Though the long rail method that pushes can be used for the laying of welded long rails construction of non-fragment orbit, but in the process that pushes long rail,, rail downwarp meeting props up a pad roller or a rail clip because answering back to, cause the security incident that breaks rail clip or cause other, and efficiency of construction is very low.
