The ballastless bed rail track-laying machine of high-speed railway pusher
Technical field
The utility model relates to a kind of railway track laying equipment, is specifically related to ballastless bed rail track-laying machine pusher.
Background technology
Along with the progress of society, rhythm of life is in continuous quickening, and the people are also more and more faster to the rate request of the vehicles, China Railway through several times the speed-raising after, the operation of original rail track has reached the limit.Seek out higher overall trip speed, must carry out the transformation of infrastructure to existing rail track, or build new railway.The every segment length of the rail of original rail track is 25 meters, can steel rail laying be arrived the precalculated position by manpower or lifting appliance.The single rail length of existing high-speed railway is 500 meters, and every meter long weight is 60 kilograms, and 60 single 500 meters long rails weigh 30 tons, and such steel rail laying to the precalculated position, is difficult to accomplish by manpower or general lifting appliance.
Summary of the invention
The purpose of this utility model is to provide a kind of overall structure simple, easy to operate, the flexible movements of folder rail, and reliable in quality pushes the strong ballastless bed rail track-laying machine of the high-speed railway pusher of power.
The utility model comprises the body seat, push motor, installation is hung, upper and lower wheel carrier and clamping cylinder, its main feature is: described upper and lower wheel carrier hinge hangs over to install and hangs on, be separately installed with on the bearing support of upper and lower wheel carrier and push running roller up and down, push running roller and drive by the propelling movement motor that is located on the body seat; Two oil cylinder earrings of clamping cylinder are connected to up and down on the wheel carrier.
The utility model adopts the friction wheel transmission principle.Simple in structure, handling safety, convenience are pressed from both sides rail, are sent the rail flexible movements, and reliable in quality pushes the power foot, and cost is low.Ballastless bed steel rail laying for 60 kilograms of 500 meters, every meter weight of the single rail length of high-speed railway is quick, and is convenient.

The specific embodiment
The utility model comprises installation and hangs 1, upper and lower wheel carrier 2,4, and respectively one of body seat 8, clamping cylinder 6 pushes running roller 5, pushes respectively two in motor 7.Upper and lower wheel carrier 2,4 by bearing pin hinged be suspended on to install hang on 1, two oil cylinder earrings 3 of clamping cylinder 6 are connected to up and down on the wheel carrier 2,4.Be separately installed with on the bearing support of upper and lower wheel carrier 2,4 and push running roller 5 up and down, push running roller 5 and drive by the propelling movement motor 7 that is located on the body seat 8.
Change the extension elongation of clamping cylinder 6 piston rods, can regulate the spacing that pushes running roller 5 up and down.Clamping cylinder 6 chamber pressures are regulated by reducing valve, can regulate the thrust that pushes 5 pairs of rail of running roller up and down.Two propelling movement motors 7 drive respectively and push running roller 5 motions up and down.Push running rollers 5 when clamping rail when two, whole wheel carrier is suspended on to install and hangs on 1, thereby the normal pressure size that has guaranteed to push up and down 5 pairs of rail of running roller is identical, inevitablely guarantee that also the driving force of 7 pairs of rail of two propelling movement motors is identical.The fluid pressure line that pushes motor 7 is installed in parallel, and the pushing speed of rail depends on the flow of hydraulic system, and the pressure of hydraulic system depends on the resistance that rail pushes.
