Description
Technical field
The utility model relates to the railroad track technical field, and especially various different interorbitals have the transition rail of special-shaped butt joint.
Background technology
Rail is to be positioned under the train wheel, to bear the weight of train, and the used steel bar equipment of guiding train direction of advance.Its function provides the surface of a resistance minimum for train operation, and wheel load is passed to the rail lower part.Rail type is mainly (75,60,50,43,38) kg/m with every meter quality integer representation roughly, China's current standard steel rail type.60kg/m and above be heavy rail, 50kg/m is medium-sized, 43kg/m and followingly is light-duty rail.The rail type that adopts on the circuit should adapt to railway transporting amount, permissible velocity and axle heavy phase.
Dissimilar tracks adopts dissimilar rail.The rail that connects two different models, the past, normal compromise joint bar and the bolt of adopting connected, and required the alignment of two tread faces and working edge.The method of taking progressively (75～60 types, 60～50 types, 50～43 types etc.) transition was also once arranged, solved the connectivity problem between dissimilar rail.From present technology, transition between weight, light rail, 2 of need and above heterotypic rail are finished at least, and the spare part specification increases, and brings inconvenience to the scene thus.
For this reason, people find out a kind of way again and solve this type of problem.Promptly adopt different manganese rail to realize that a step transition puts in place.Because only only limiting to straight line sleeper location, steel-casting characteristic limitations, different manganese rail use, for present then none solution that settles at one go of the track of curve rail and other classifications.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of and can realize between heavy and light shaped steel rail that one step transition puts, is suitable for various sleeper classifications and straight line and the general special-shaped transition rail of curve rail in place for overcoming above-mentioned deficiency.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of special-shaped transition rail, it is characterized in that forming by benchmark rail section, changeover portion and new standard gauge section three parts, wherein, benchmark rail section is consistent with a kind of standard basis rail that will dock, new standard gauge section is consistent with the another kind of new rail that will dock, changeover portion constitutes the transition that is connected between benchmark rail section and new standard gauge section two parts, and three sections rail level is with high.
By technique scheme, between benchmark rail section and changeover portion, changeover portion and new standard gauge are intersegmental all flatly is provided with vertical transition arcs; Between benchmark rail section and changeover portion, changeover portion and new standard gauge is intersegmental all vertically is provided with vertical transition arcs with rail level.
By technique scheme, described vertical transition arcs and vertically transition arcs be the transition arcs that the specification of two kinds of tracks that radius can dock is as required set.
By technique scheme, transition section length is less than a sleepers sky.
By technique scheme, special-shaped transition rail is height and all adjustable transition rail of width.
By technique scheme, special-shaped transition rail can move the transition arcs of adjusting at vertical direction by vertical transition arcs for height, and simultaneously, special-shaped transition rail also can move the transition arcs of adjusting by vertical transition arcs in the horizontal direction for width.
By technique scheme, described new standard gauge section is than light 1～4 model of benchmark rail section.
By technique scheme, described new standard gauge Duan Weijing high temperature heating, mould are annotated the rail section that rolls out unnecessary molten steel postforming grade.
Concrete, vertical transition arcs rises, and orbit altitude shortens; Vertically move in the transition arcs, track width narrows down.Transition section length is less than a sleepers sky, to guarantee that rail joint two sleepers are in same plane and function of use thereof.
The beneficial effects of the utility model:
The special-shaped transition rail of the utility model, simple in structure easy to assembly, height and the width that to adjust rail level that move by transition arcs, make dissimilar rail all can on an one steel rail, transition finish, its scope of application is not only applicable to the straight line rail and is applicable to the curve rail, and not only sleeper but also concrete sleeper location all can be general, because one step transition puts in place between heavy and light type rail, matching component significantly reduces, thereby makes that the butt joint cost significantly reduces, construction and easy to maintenance.

Among the figure: (1) special-shaped transition rail, (2) benchmark rail section, (3) new standard gauge section, (4) changeover portion, (5) rail level, (6) are transition arcs, (7) vertical transition arcs, (R) vertical transition arcs radius, (R1) vertical transition arcs radius vertically
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing, but do not limit the utility model.
The special-shaped transition rail 1 of the utility model, be that the end benchmark rail section 2 consistent with the benchmark rail is set on the benchmark base of the rail plinth that will dock, the other end is for annotating the new standard gauge section 3 that rolls out unnecessary molten steel postforming grade through high temperature heating, mould, 3 of benchmark rail section 2 and new standard gauge sections are made of changeover portion 4 and are connected transition, and each intersegmental rail level 5 is with high.
Benchmark rail section 2 takes vertical transition arcs 6 to be connected with vertical transition arcs 7 with new 3 of standard gauge sections.The specification of two kinds of tracks that vertical transition arcs radius R 1 and vertical transition arcs radius R all can dock is as required set.Vertically move benchmark rail 2 narrowed width in the transition arcs 6; Vertical transition arcs 7 rises, and benchmark rail 2 highly shortens, and progressively transition is the new standard gauge section 3 than benchmark rail section 2 light 1～4 model.Changeover portion 4 length are less than a sleepers sky, to guarantee that rail joint two sleepers at grade and function of use.Rail end connecting cleat (where be arranged on, need diagram) scope is the complete section that mould is annotated the new standard gauge section 3 that rolls.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalence of being done according to the utility model claim changes, and still belongs to protection domain of the present utility model.
