Description
Technical field
The utility model relates to a kind of rail fastening, particularly a kind of elasticity separated rail fastening of capable of regulating Rail distance.
Background technology
, along with the fast development of Chinese track traffic, withhold the fastener form of rail and also constantly updating.The effect of rail fastening is the tram that keeps rail, prevent that rail from, in length and breadth to displacement, providing certain track elasticity, and the power that rail is suffered passes to sub rail foundation.Fastener also will have certain gauge adjustment performance, and the gauge that is caused with solution curved section rail wear and construction error etc. transfinites.
Existing comparatively ripe steel rail spring separated rail fastening, comprise backing plate, rail is placed on backing plate, the left and right sides of rail all is equipped with anchor bolt, spring, T-shaped bolt and Insulation rail distance keeper on backing plate, the backing plate left and right sides is equipped with boss, and backing plate is fixed on sleeper through anchor bolt, and T-shaped bolt passes boss spring is fixed on backing plate, the forelimb of spring is withheld on rail through the insulation track gauge block, and afterbody is resisted against on boss.Offer slotted hole on backing plate, the screw rod of anchor bolt passes from this slotted hole, so that backing plate is fixed on sleeper.An if cushion block, perforate on cushion block, the screw rod of anchor bolt also passes from the hole of cushion block, cushion block is pressed between the spring washer and backing plate below the head of anchor bolt, relies on the frictional force between briquetting and spring washer and backing plate to stop the movement of fastener system with respect to sleeper.For realizing gauge adjustment, a kind of scheme is that cushion block is the Flat gasket that top and bottom are plane, while unclamping anchor bolt, can mobile horizontal cushion block or backing plate, all can adjust gauge, tighten anchor bolt after adjustment, Flat gasket is pressed between the head and backing plate of anchor bolt.But upper plane and the lower plane of the Flat gasket of this scheme have all born huge stiction or kinetic force of friction, quick abrasion, and coupling mechanism force is little, easily slides in use.
Another kind of scheme is that cushion block coordinates through the sawtooth engagement with backing plate, adjusts gauge and can realize by the position of engagement of adjusting cushion block and backing plate, and tighten anchor bolt after adjusting, and can prevent the slip on gauge direction of cushion block with respect to backing plate.This kind mode is the gauge adjustment that level is arranged, and adjusts precision and depends on the accuracy of manufacture of cushion block and backing plate sawtooth, and because teeth sizes is little, wayward machining accuracy, improved processing cost.
The utility model content
The utility model provides a kind of steel rail spring separated rail fastening, adjusts Rail apart from flexible, and required component are few, and wearing and tearing are little while using.
For achieving the above object, the technical solution adopted in the utility model is: a kind of steel rail spring separated rail fastening, comprise backing plate, rail is placed on backing plate, the left and right sides of rail all is equipped with anchor bolt, spring, T-shaped bolt and Insulation rail distance keeper on backing plate, the backing plate left and right sides is equipped with boss, backing plate is fixed on sleeper through anchor bolt, T-shaped bolt passes boss spring is fixed on backing plate, the forelimb of spring is withheld on rail through the insulation track gauge block, afterbody is resisted against on boss, is provided with spring washer between the head of anchor bolt and backing plate;
Also comprise two briquettings, this two briquetting is assemblied in the rail left and right sides, each briquetting is big up and small down polygon wedge shape all, offer the vertical cylindrical hole of axis on briquetting, the screw rod of anchor bolt passes from this cylindrical hole, briquetting is pressed between spring washer and backing plate, cylindrical hole is cylindrical hole, its aperture is more than or equal to anchor bolt screw rod external diameter, perhaps, this cylindrical hole is the elongated slot cylindrical hole, and its hole major diameter is greater than the screw rod external diameter of anchor bolt, and the hole minor axis is more than or equal to the screw rod external diameter of anchor bolt;
On described backing plate, the left and right sides is equipped with shoulder block, two briquettings of the rail left and right sides are used in combination, each briquetting all has even number wedge inclined-plane, the shoulder block inclined-plane that arranges on wedge inclined-plane in this even number wedge inclined-plane and shoulder block against, the boss inclined-plane that arranges on another wedge inclined-plane and boss against; Each wedge inclined-plane on briquetting and the centerline hole of the cylindrical hole on this briquetting distance are all unequal;
Offer slotted hole on described backing plate, its hole major diameter is greater than the screw rod external diameter of anchor bolt, and the hole minor axis is more than or equal to the screw rod external diameter of anchor bolt, and the screw rod of anchor bolt passes from this slotted hole, so that backing plate is fixed on sleeper.
Related content in technique scheme is explained as follows:
1, in such scheme, the quantity on the even number wedge inclined-plane on described briquetting is four.
2, in such scheme, one or more in the wedge inclined-plane on described briquetting, shoulder block inclined-plane and boss inclined-plane has wearing coat.
3, in such scheme, described backing plate is plastic plate or iron plate.
4, in such scheme, the sleeve pipe of described anchor bolt through being embedded in advance in sleeper is connected with sleeper.
5, in such scheme, even number wedge inclined-plane, shoulder block inclined-plane and the boss inclined-plane of described briquetting cooperatively interact both in, one is provided with flange, another one is provided with groove, described flange embeds in groove, with moving forward and backward of the restriction relative shoulder block of briquetting or relative boss.
6, in such scheme, described briquetting is hardware or non-metallic member.
The utility model operating principle is: two briquettings of rail both sides are up big and down small polygon wedge shape, cylindrical hole on briquetting is cylindrical hole, its aperture is more than or equal to anchor bolt screw rod external diameter, perhaps, this cylindrical hole is the elongated slot cylindrical hole, its hole major diameter is greater than the screw rod external diameter of anchor bolt, and the hole minor axis is more than or equal to the screw rod external diameter of anchor bolt; Offer slotted hole on backing plate, its hole major diameter is greater than the screw rod external diameter of anchor bolt, and the hole minor axis, more than or equal to the screw rod external diameter of anchor bolt, after all guaranteeing to unscrew anchor bolt, can move backing plate with respect to sleeper, has also just adjusted the gauge of the rail on the backing plate.
Two briquettings of the rail left and right sides are used in combination, and each wedge inclined-plane of briquetting and the centerline hole of the cylindrical hole on this briquetting distance are all unequal.While adjusting gauge, unscrew and take out anchor bolt, spring washer and briquetting, can move backing plate, carry out gauge adjustment, after adjustment, briquetting is placed in again between the spring washer and backing plate below the head of anchor bolt, but be that briquetting has been changed direction at this moment, make its different wedge inclined-plane and the shoulder block inclined-plane on backing plate against, corresponding another different wedges inclined-plane just with the boss inclined-plane against, realize location after tightening anchor bolt, the movement of restriction rail, backing plate, at this moment, two wedge inclined-planes of briquetting change with respect to the distance of anchor bolt axis thereupon.
