Description
Technical field
The invention belongs to railway switch technical fields, and in particular to a kind of assembled frog fork core structure.
Background technique
Conventional combination railway frog fork the heart select casting potassium steel, forging potassium steel or alloy steel material integrally manufacture, exist with
Lower problem:
(1) fork core material is casting potassium steel, and manganese fork heart wall wall thickness dimension and the more common high manganese steel frog of transverse bar are higher by
By about one time, so that the more common high manganese steel frog of railway frog integral rigidity is higher, it is easy to cause heart rail small disconnected under wheel repeated stock
Face premature failure.
(2) fork core material is forging potassium steel, and since manganese fork heart volume is excessive, structure is in slender rod piece, and forging difficulty is big,
Cause institutional framework uneven, it is internal linear, as cast condition rarefaction defect easily occur, restrict forging potassium steel assembled frog service life
Stability.
(3) the fork heart integrally selects forging potassium steel or alloy steel making, compared with casting potassium steel, increase manufacture at
This.
Summary of the invention
The present invention provides a kind of assembled frog fork core structure, to overcome the shortcomings of prior art.
The technical scheme adopted by the invention is that: a kind of assembled frog fork core structure, including fork heart wing rail assembly, the fork heart heart
Rail assembly, the fork heart wing rail assembly are potassium steel casting, and fork heart heart rail assembly is potassium steel forging or alloy steel making；It is described
Pitch heart wing rail assembly rear end have V-arrangement mounting groove, and V-arrangement mounting groove two sidewalls be in symmetrical inclined-plane I, make V-arrangement mounting groove
Trapezoidal structure on section；The front end of the fork heart heart rail assembly is v-shaped structure, and its two sidewalls is in symmetrical inclined-plane II, makes V
Shape structure trapezoidal structure on section；The inclined-plane I is identical as II gradient of inclined-plane；In the v-shaped structure insertion V-arrangement mounting groove
And it is connected and fixed and is integrated with fork heart heart rail assembly front end by high-strength bolt adjutant fork heart wing rail assembly rear end.
The gradient on the inclined-plane I and inclined-plane II is 3 °~5 °.
V-arrangement mounting groove two sides are symmetrically arranged with four through-holes；The v-shaped structure is equipped with four corresponding with four through-holes
Via hole, and installing the through-hole, via hole by four high-strength bolt pairs will fork heart wing rail assembly rear end and fork heart heart rail assembly
Front end, which is connected and fixed, to be integrated.
The position of corresponding four through-holes sets that there are four bolt pair mounting grooves on the fork heart wing rail assembly lateral surface.
Compared to the prior art, the invention has the benefit that
(1) forging potassium steel or the alloy steel material manufacture that position heart rail is easily lost using excellent in mechanical performance in the heart will be pitched,
Wing rail selects the manufacture of block cast potassium steel, different to railway frog different parts shock loading by wheel during railway frog is on active service, configuration
The material of different performance, has given full play to material property, extends whole group railway frog service life.
(2) forging potassium steel manufacture fork heart heart rail is selected, forging potassium steel dosage can be substantially reduced, simplify structure, dropped
Low forging difficulty, reduces manufacturing cost, improves heart rail forging quality.
(3) alloy steel making is selected to pitch heart heart rail, hence it is evident that reduce steel alloy dosage, fork heart manufacturing cost can be significantly reduced.

Specific embodiment
The present invention is described in detail for 1-7 and specific embodiment with reference to the accompanying drawing.
A kind of assembled frog fork core structure, including fork heart wing rail assembly 2, fork heart heart rail assembly 1, the fork heart wing rail assembly
2 cast for potassium steel, and fork heart heart rail assembly 1 is potassium steel forging or alloy steel making；2 rear end of fork heart wing rail assembly has
V-arrangement mounting groove 2-1, and the V-arrangement two sidewalls mounting groove 2-1 are in symmetrical I 2-4 of inclined-plane, make V-arrangement mounting groove 2-1 on section in ladder
Shape structure；The front end of the fork heart heart rail assembly 1 is v-shaped structure 1-1, and its two sidewalls is in symmetrical II 1-3 of inclined-plane, makes V-arrangement
Structure 1-1 trapezoidal structure on section；The gradient of I 2-4 of inclined-plane and II 1-3 of inclined-plane is 3 °~5 °；The v-shaped structure
Before 1-1 is embedded in V-arrangement mounting groove 2-1 and will pitch 2 rear end of heart wing rail assembly and fork heart heart rail assembly 1 by high-strength bolt pair 3
End, which is connected and fixed, to be integrated.
The two sides V-arrangement mounting groove 2-1 are symmetrically arranged with four through-hole 2-2；The v-shaped structure 1-1 is equipped with and four through-holes
The corresponding four via hole 1-2 of 2-2, and by the way that four high-strength bolt pairs 3 install the through-hole 2-2, via hole 1-2 will pitch heart wing rail
2 rear end of assembly is connected and fixed with fork 1 front end of heart heart rail assembly and is integrated.It is four corresponding on 2 lateral surface of fork heart wing rail assembly
The position of through-hole 2-2 is set there are four bolt pair mounting groove 2-3.
The present invention uses same material or same manufacturing process for the existing assembled frog fork heart, and manufacturing cost is high, difficult
Big problem is spent, fork heart heart rail and fork heart wing rail are separately fabricated, and pitch heart heart rail using potassium steel forging or alloy steel making, fork
Heart wing rail is cast using potassium steel, then forms the fork heart using composite assembly structure.Reducing forging potassium steel or steel alloy makes
With cost, heart rail quality is improved, fork heart casting potassium steel and forging potassium steel or alloy steel material performance is given full play to, extends
Whole group railway frog service life.And it pitches heart heart rail assembly and pitches heart wing rail assembly and pacify on section in the big wedge shape in the small lower part in top
Assembling structure prevents from crossing the upward vibration of Che Shixin rail.
Above-described embodiment, only presently preferred embodiments of the present invention, the practical range being not intended to limit the invention, thus it is all with
The equivalent variations that content described in the claims in the present invention is done should all be included within scope of the invention as claimed.
