Abstract
The invention discloses a movable-point crossing with long service life which is made of bainitic steel and in which the point is inosculated favorably with the tyre tread of railway. The movable-point crossing wing rail is made of AT rail and the long-short point is made of ordinary steel rail and matched with a groove-shaped coupler lock; the point of the movable-point crossing is formed by combining long points and short points; elastic bendable section and crossing root rail of the point are cancelled, the root thereof having a movable joint so as to form shortened form. Being light in weight, the shortened-form movable-point crossing can be replaced without large cranes.
Description
Technical field:
The present invention is the parts in a kind of railway switch, and a kind of movable-point crossing can be with rolling, and welding and machine form, and enter different tracks in order to guided vehicle.
Background technology:
Existing movable-point crossing uses dwarf forms special section rail to make with common rail or potassium steel casting, heart rail.Because dwarf forms special section rail is lower than jack per line rail, heart rail section bending resistance is poor, can not satisfy the needs of heavy haul transport; Existing movable-point crossing is with common rail material manufacturing, and intensity is low, and is not wear-resisting; Heart rail and railway wheel tread coincide bad, and fall short of application life; Existing movable-point crossing is not only long but also heavy, need employ large-scale crane during replacing, closes contact net electric power, and interference on the road is bigger.
Summary of the invention:
It is strong to the objective of the invention is to invent a kind of heart rail section bending resistance, can satisfy the heavy duty movable-point frog of heavy haul transport needs; Its heart rail and railway wheel tread coincide, and the bainitic steel manufacturing of heart rail and wing rail can prolong life-span of movable-point crossing greatly; Further heart rail is only by long heart rail, and short heart rail combines formation shortening type movable-point crossing, and the movable-point crossing of shortening type is in light weight, and to need not to employ large-scale crane promptly replaceable.
The heart rail front thigh that makes triangular in shape can be driven a vehicle thereby technical scheme one of the present invention is achieved in that the point plane that makes heart rail; The convex curve that matches with wheel tread and wheel-rim shape is processed on its top, triangle both sides respectively, and wheel can pass through heart rail smoothly; Have backing plate can support heart rail under the heart rail, heart rail can slide on backing plate; Wing rail links to each other with backing plate by securing member with a spacing rail brace at least can keep the relative position of wing rail: the hook lock of heart rail have with supporting grooved section structure or the hook grooved section structure of the heart rail flange of rail, can pull heart rail by the motion of hook lock; Spacing rail brace has the hook that matches with shoulder block, and when rail brace and wing rail were linked to be integral body with nut, the outside that is hooked in shoulder block can prevent to move in the wing rail; The inboard no fastener of wing rail, spacing rail brace can play the fastener effect; Heart rail main body has I-shaped section structure and heart rail section can improve heart rail section bending resistance than wing rail section length, and long heart rail tip has the section structure of inverted T-shaped, has improved the most advanced and sophisticated bending resistance of heart rail, all can satisfy the needs of heavy haul transport; Wing rail has the thick web of the rail, low clearance, the asymmetric AT section structure of flange of rail left and right sides leg so that supporting with heart rail.
The heart rail front thigh that makes triangular in shape can be driven a vehicle thereby technical scheme two of the present invention is achieved in that the point plane that makes heart rail; The convex curve that matches with wheel tread and wheel-rim shape is processed on its top, triangle both sides respectively, and wheel can pass through heart rail smoothly; Heart rail is by long heart rail, and short heart rail combines, and the root of long heart rail and short heart rail has movable joint, owing to adopt movable joint, has cancelled the elasticity bendable section and the brached rail of long heart rail, thereby forms shortening type movable-point crossing; The both sides of movable joint have clamping plate or bridge or the gap bridge interval iron rail with fastening movable joint place.Further, make it have supporting capacity thereby make bridge or gap bridge interval iron top have the tread face that contacts with wheel tread, tread face both sides have buffering suface to reduce impact force; The section main body of gap bridge interval iron is the U font can save material, and the biside plate of U font gap bridge interval iron has bolt hole so that be connected with rail.Further, the anti-creep clamping plate are housed on the wing rail, the bottom of anti-creep clamping plate has flange, flange inserts in the hole of switch base plate or has at least one to have flange with the clamping plate of the root movable joint both sides of duration heart rail and short heart rail or bridge or gap bridge interval iron, flange inserts in the hole of switch base plate, can prevent that like this wing rail heart rail from creeping.Wing rail in addition, long heart rail and short heart rail have at least one to have flange, and flange inserts in the hole of switch base plate or switch base plate has flange, and flange inserts wing rail, in the hole of long heart rail and weak point heart rail, can prevent that so also the wing rail heart rail from creeping.Further, long heart rail is welded into a whole by the in-line weld seam with short heart rail by T shape weld seam or long heart rail with short heart rail and point, can improves the globality of heart rail.
Technical scheme three of the present invention is achieved in that the section main body of heart rail and wing rail has at least one to have one of following H-shape cross section structure:
1. the special section rail (special section wing rail) of inclined to one side H-shape cross section of the thick web of the rail
The special section rail of the asymmetric flange of rail of the 2. thick web of the rail (AT rail)
3. common rail
The structure that the section main body has I-shaped can make wing rail heart rail section distribution of material rationally reduce the consumption of expensive alloy steel, adopts existing shaped steel such as special section wing rail, and AT rail, common rail can be removed the input of making new roll new technology from.
Heart rail and wing rail be with particularly bainitic steel manufacturing of high-strength and high-toughness steel, the intensity height, wear-resisting, the life-span long, can satisfy the needs of heavy haul transport.The bainitic steel material has one of following chemical composition combination:
