Abstract
The utility model relates to a railway frog with wing rails and a frog core integrally designed. The utility model is characterized in that a high strength alloy steel wing rail frog core 8 of integral structure design is arranged between two wing rails 2, the front part and the middle part of the wing rail frog core 8 are respectively and fixedly connected to the wing rails 2 through screw bolt components 4, and meanwhile, two frog heel rails 5 which are made of ordinary steel rails are respectively welded on the tail ends of the wing rail frog core 8, and fixedly connected with spacers 3 and the wing rails 2 through the screw bolt components 4. The utility model has the advantages that the center rails and the wing rails have same strength and equal service life, and the demand of the over-length jointless lines within the intervals of switches is met.
Description
The utility model relates to a kind of new construction railway frog that is used on the railway switch.
Background technology of the present utility model is that this enterprise is the alloy steel fork heart welded " alloy steel core rail welded frog " patent at the central body of frog of first to file.The railroad frog of this structure is because the fork heart that adopts alloy steel to design is the part of frog centre, do not relate to wing rail, improve the advantage that the local contact fatigue strength of railway frog increases the service life it so it just has with respect to cast-in-block normal steel casting railway frog.But still have following shortcoming: because of the wing rail of gap in the frog both sides is still used the normal steel casting manufacturing, though rail head can improve case hardness through hard surfacing, its intensity index still can not be consistent with alloy steel central body of frog part; Make the life cycle of railway frog still can not reach desirable index.Wing rail and central body of frog are to manufacture individual member respectively on structure design in addition, and flangeway width is fixed with high-strength bolt by interval iron, thereby the resistance to overturning of railway frog, particularly lateral stability are also undesirable.
Goal of the invention of the present utility model is to release a kind of in the certain limit of gap in the frog at above-mentioned the deficiencies in the prior art just, adopt the integral type design of the alloy steel wing rail fork heart and make and whole endurance life reach unanimity, cycle in application life is longer, the alloyed steel strip wing rail heart rail welded frog that stability is better.
The technical scheme that realizes the present utility model purpose is: it has interval iron 3, bolt assembly 4, fork with rail 5, the high-strength alloy steel wing rail of the structure design fork heart 8 places between two wing rails 2 as a whole, and front portion, the middle part of the wing rail fork heart 8 are fixedly connected by bolt assembly 4 and two wing rails 2 respectively.Simultaneously with common rail manufacturing, and two forks that are welded as a whole of its flange of rail side are welded in the tail end of the wing rail fork heart 8 respectively with rail 5, and are fixedly connected by bolt assembly (4) and interval iron 3 and wing rail 2.
The advantage that the utility model is compared with background technology also is conspicuous: the first, train is in operation, because wheel is to the wing rail working edge serious wear before and after the theoretical nose of crossing, adopt the integral type wing rail fork heart of the alloy steel manufacturing of superhigh intensity, can realize whole railway frog equal strength substantially, thereby the application life of having improved railway frog.The second, because the wing rail and the fork heart are an integral body, directly be held between the outer wing rail, saved the part interval iron, can guarantee flangeway width effectively, the lateral stability of railway frog is strengthened, more help the interval development of railway switch overlength gapless track.
Accompanying drawing and drawing are described as follows:
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is the A-A generalized section of the utility model Fig. 1;
Fig. 3 is the B-B generalized section of the utility model Fig. 1;
Fig. 4 is the C-C generalized section of the utility model Fig. 1;
Fig. 5 is the D-D generalized section of the utility model Fig. 1;
Wherein:
1-fork heart 2-wing rail 3-interval iron 4,9-bolt assembly
The 5-fork is with rail 6,7, the 10-weld seam 8-wing rail fork heart
Embodiment: as Fig. 1, begin between the certain width section of heart rail from throat of frog, two wing rails, the 2 rail head work avris and the fork heart 1 are formed the integral type wing rail fork heart 8, it comprises that flangeway between wing rail and heart rail and throat are to one section between the theoretical tip, and adopt high-intensity alloy steel material manufacturing, the remainder of wing rail 2 still adopts common rail manufacturing, the mating part of it and the alloy steel wing rail fork heart 8 is fixed by high-strength bolt assembly 4 after adopting existing bending and machining technique to process.Two forks follow the flange of rail side of rail 5 to weld together, and still select for use common rail manufacturing, its both ends to be welded in the tail end of the wing rail fork heart 8 respectively, fixedly link by the afterbody of interval iron 3 with wing rail 2 with bolt assembly 4.
