Abstract
The utility model relates to a sleeper. The slope of the rail bottom of a rail bearing platform of an outer rail is 1 to 24, the slope of the rail bottom of a rail bearing platform of an inner rail is 1 to 40, and the height difference of the rail bottom away from the two rail bearing platforms is 25 mm. As the slope of the rail bottom under the outer rail is large, a large part within a reference line of a wheel tread act on the rail surface, the outwards deflective part of the reference line of the wheel tread on the inner rail acts on the outwards deflective of a center line, wheels on the outer rail do not slip, and wheels on the inner rail do not run idle, which reduces the side wear of wheel rims on the rails and simultaneously reduces the wear of wheel pairs of rolling stock.
Description
The utility model provides a kind of sleeper that is suitable at circuit turning steel rail laying, belongs to the construction work member.
When turning in order to eliminate train, the influence of centrifugal force in the prior art, except the restriction train running speed, at the turning, also takes outer rail to be higher than the laying method of interior rail.But wheel is to the outer rail and the interior rail of the pairing curve circuit of axle unit's steering angle, and the Widening on Curve condition that is uneven in length and both just satisfies defined in the relevant technologies standard is still not enough so that take turns right tread and reasonably contact with the rail face.Especially occur samely taking turns wheel week rollings poor and two wheels poor (curve difference of outer rail, interior rail) that two wheel treads are moved do not wait on two strands of rail.This can cause wheel spin on the inner line of rail, grinds commentaries on classics, cause the rail's end portion inboard rail lip to occur.Outer path is got on the bus to take turns and then sliding friction can be occurred, and the inboard end face fecund of this rail is given birth to the wearing and tearing of scratch crackle form, and the shearing scratch crackle that the suitable current of traffic of 45 then appears in the rail level inside edge causes the serious abrasion of rail.The above-mentioned difficult point of prior art had both limited the travel speed of train, had reduced railway transport capacity, also owing to need to safeguard and change the rail that is worn and torn too early, had increased cost of transportation more.
At the above-mentioned deficiency in the engineering of existing railway curve location, the purpose of this utility model, providing a kind of rail and wheel tread contact area of making strengthens, the not enough rational state of stress distribution when changing existing rail surface and contact, reduce wheel rim to the inboard extruding force of silent partners rail head of rail with wheel tread, thus the curve location sleeper of minimizing rail abrasion amount.
Above-mentioned purpose of the present utility model, realize by following technical measures:
Sleeper provided by the utility model, the flange of rail gradient difference of two support rail platforms, two support rail platforms are also inequality apart from sleeper bottom surface height.Be embodied in the flange of rail gradient 1: 20～1: 30 of outer rail support rail platform, the flange of rail gradient of interior rail bearing rail platform 1: 35～1: 45; Rail bearing rail platform 20mm～30mm at the bottom of the sleeper in outer rail support rail platform is higher than at the bottom of the sleeper.
When train driving is being laid on the sleeper provided by the utility model,, the wheel tread reference line is acted on the rail face with interior major part because the rail cant under the high rail rail is bigger.Rail cant under the interior rail steel rail is less, but since on the interior rail wheel tread and rail surface inboard the space of perk is arranged, so the outer partially part of the tread reference line of wheel act on rail on the interior rail center line partially outside.These take turns the different of right tread and two bursts of rail surface parts of the force, make that sliding does not appear in wheel on the outer rail, and idle running does not appear in wheel on the interior rail, has reduced the lateral wearing of rail on the external path of wheel rim, reduces the right wearing and tearing of rolling stock wheel simultaneously yet.Because wear extent reduces, the repair and replacement number of times reduces, and has reduced cost of railway traffic.Again because on the outer rail active force major part of rail wheel vertically act on the rail center line and the rail face on, even if by the higher train of speed, can not produce derailing and capsizing case yet.
Accompanying drawing 1 is the front view of curve provided by the utility model road with sleeper, and accompanying drawing 2 is vertical views of sleeper shown in the accompanying drawing 1.Below in conjunction with accompanying drawing,, further narrate technical characterictic of the present utility model by most preferred embodiment.
Curve location sleeper is that support rail platform (1) flange of rail gradient of a kind of concrete sleeper (2) outer rail is 1: 24, and support rail platform (3) flange of rail gradient of interior rail is 1: 40, and outer, interior two support rail platforms are apart from sleeper bottom surface discrepancy in elevation 25mm.
Claims (2)
1. one kind is suitable for the sleeper laid at the rail track turning, the flange of rail gradient 1: 20～1: 30 that it is characterized in that outer rail support rail platform, the bottom sloping of interior rail bearing rail platform 1: 35～1: 45, outer rail support rail platform in distance is higher than at the bottom of the sleeper rail bearing rail platform at the bottom of the sleeper apart from 20mm～30mm.
2. sleeper according to claim 1 is characterized in that the support rail platform flange of rail gradient of outer rail is 1: 24, and the support rail platform flange of rail gradient of interior rail is 1: 40, and outer, interior two support rail platforms are apart from sleeper bottom surface discrepancy in elevation 25mm.
