Abstract
The utility model discloses a novel high manganese steel frog which comprises an independent first wing rail, an independent second wing rail and a frog point rail between the first wing rail and the second wing rail, and the frog point rail, the first wing rail and the second wing rail are fixed through bolts; the frog point rail comprises a tip end and two rail parts, and the tip end is matched with the two rail parts through matching faces; a first separating block is arranged between the two rail parts. The wing rails, the tip end of the frog point rail and the rail parts of the frog point rail are independently cast, and due to the wing rails, the tip end of the frog point rail and the rail parts of the frog point rail are respectively and independently cast, respectively cast castings are small and simple in structure, and the quality of the castings can be improved. The components can be assembled together through a detachable structure and can be independently replaced after being damaged, the whole high manganese steel frog does not need to be replaced and is convenient to achieve, and cost is reduced.
Description
Technical field
The utility model relates to track technical field, especially relates to a kind of novel high manganese steel frog.
Background technology
The railway frog great majority that change its course that use on railway are at present block cast formula high manganese steel frogs, between central body of frog and two wing rails, there is larger space, actual point of frog and two wing rail working edges form an idle space in the place of approaching most like this, train is in the time changing its course, wheel press wheel rim track by railway frog to tongue 50 ends, this segment distance be the fastest section of railway frog wearing and tearing and application life critical section, the theory tip of especially changing its course, when wheel rim travels to theoretical tip, the area of wheel rim carrying is minimum, easily make the railway frog limit of collapsing, wearing and tearing, when serious, crack, cause road under railway frog, can not use.
Because the each parts of railway frog are cast article, structure is too complicated again, inevitably can have casting flaw, these defects are under train action of long-term load, can cause the crackle of railway frog, cause the damage of railway frog, particularly the damage of the wing rail of railway frog both sides is very ordinary.Because train is through out-of-date constantly rolling, the serious wear of wing rail, hardness also improves constantly, and easily occurs peeling off piece phenomenon, causes the hurt of railway frog; The railway frog of hurt will jeopardize the traffic safety of train, thereby must be changed in time, and railway frog needs integral replacing, has greatly increased the running cost of track traffic.
Utility model content
For prior art deficiency, technical problem to be solved in the utility model is to provide a kind of novel high manganese steel frog, and the each component combination of its high manganese steel frog is set together, and damage can be changed separately.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of novel high manganese steel frog, comprise independently wing rail I and wing rail II and be located at wing rail I and wing rail II in the middle of central body of frog, between described central body of frog, wing rail I and wing rail II, be bolted; Described central body of frog comprises point and two orbit portions, between point and two orbit portions by suitable coordinate; Between described two orbit portions, be provided with spacer block I.
Further, the face matching between described point and two orbit portions is step surface.
Between the wing rail I of described point and two orbit portion mated position places and both sides and wing rail II, be provided with spacer block II, set bolt is fixed together through wing rail I, wing rail II, spacer block II, point, two orbit portions.
Between described spacer block I and two orbit portions, pass and be fixed together by bolt.
Between the tip end of described point and the wing rail I of both sides and wing rail II, be provided with spacer block III, set bolt is fixed together through wing rail I, wing rail II, spacer block III and point.
Described point material is high-strength wear-resistant alloy steel.
Described point matches the height of upper surface of end lower than the height of two orbit portion upper surfaces with two orbit portions.
The utility model compared with prior art, has the following advantages: the tip portion of wing rail, central body of frog and rail portion are all distinguished to casting separately, and casting is little, simple in structure respectively, can improve casting quality; And each parts fit together by demountable structure, parts damages can be changed separately, and without integral replacing, it is convenient to change, and reduces costs.
Accompanying drawing explanation
Below the mark in the each width accompanying drawing of this manual expressed content and figure is briefly described:
Fig. 1 is the utility model high manganese steel frog organigram.
Fig. 2 is the utility model central body of frog organigram.
In figure: 1. wing rail I, 2. wing rail II, 3. the fork heart, 4. track I, 5. track II, 6. spacer block I, 7. spacer block II, 8. spacer block III.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, high manganese steel frog of the present utility model, comprise independently wing rail I 1 and wing rail II 2 and be located at wing rail I 1 and wing rail II 2 in the middle of central body of frog, wherein, central body of frog comprises point and two orbit portions, point is the fork heart 3, two orbit portions are respectively track I 4 and track II 5, together with matching by step surface between one end of point and two orbit portions, be specially, both sides, point one end are equipped with step, two orbit portion inner sides are provided with the structure suitable with point both sides step, match together by step surface, coordinate area large, fixing more reliable, and the cooperative end part of track I 4 and track II 5 is played a supporting role, be not prone to the limit phenomenon of collapsing.
When preventing the work of two orbit portions, track I 4 and track II 5 is stressed moves to centre, between track I 4 and track II 5, be provided with spacer block I 6, spacer block I 6 is provided with the fixing hole corresponding with hole on two orbit portions, together with being fixed with the hole in spacer block I 6 through two orbit portions by high-intensity bolt.
For improving the constant intensity between two orbit portions and point, between the wing rail I of the point of central body of frog and two orbit portion mated position places and both sides and wing rail II, be provided with spacer block II 7, set bolt is fixed together through wing rail I 1, wing rail II 2, spacer block II 7, point, two orbit portions.
And being provided with spacer block III 8 between the tip end of point and the wing rail I of both sides and wing rail II, set bolt is fixed together through wing rail I, wing rail II, spacer block III 8 and point.
Point material is high-strength wear-resistant alloy steel, individual components, and cost increases less, and can increase the application life of railway frog.
Point matches the height of upper surface of end lower than the height of two orbit portion upper surfaces with two orbit portions, reduce wheel running resistance.
Each parts fit together by demountable structure, and single component weight is less, are convenient to installing component and damage and can change separately, without integral replacing, reduce costs.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
