Description
Technical field
The invention belongs to railway switch technical fields, and in particular to a kind of welding assembled frog.
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 welding assembled frog, to overcome the shortcomings of prior art.
The technical scheme adopted by the invention is that: a kind of welding assembled frog has fork heart assembly, wing rail and pitches with rail,
Two wing rails are symmetricly set on the two sides of fork heart assembly, and two forks are symmetricly set on the two sides of fork heart assembly tail portion, and position with rail
Between two wing rails；The fork heart assembly is by the leading portion that is easily lost and is not easy the back segment being lost head and the tail and docks and pass through flash welding
The leading portion for connecing and being fixed as one, and be easily lost is potassium steel forging molding, and being not easy the back segment being lost is potassium steel casting and forming；Institute
It states and is respectively equipped with through-hole on the web of the rail of the weld seam two sides fork apex of the heart rail of Flash Butt Welding, and symmetrically set between through hole and two sides wing rail
There is the interval iron of adaptation, and being each passed through rail washer, interval iron, through-hole and wing rail by two bolt pairs will be after fork apex of the heart rail
End is connected and fixed with two sides wing rail to be integrated.
It is on the section of 60~100mm that the weld seam of the Flash Butt Welding, which is located at fork apex of the heart rail rear end rail head width,.
Compared to the prior art, the invention has the benefit that
(1) simplify the fork heart and forge potassium steel part-structure, forging potassium steel dosage reduces 40%, it is difficult to reduce forging
Degree, so that forging stock interior tissue is more uniform, improves forging stock internal soundness, reduces manufacturing cost.
(2) fork heart same material is welded, it can be ensured that excellent welding quality.
(3) the weld seam two sides fork heart and wing rail are reinforced, and are being guaranteed safety in utilization, are being optimized force structure two of heart rail
Aspect has played double action.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the structural schematic diagram of present invention fork heart assembly；
Fig. 3 is E-E cross-sectional view in Fig. 1.
Specific embodiment
The present invention is described in detail for 1-3 and specific embodiment with reference to the accompanying drawing.
A kind of welding assembled frog has fork heart assembly 1, wing rail 5 and fork with rail 9, and two wing rails 5 are symmetricly set on the fork heart
The two sides of assembly 1, two forks are symmetricly set on the two sides of fork 1 tail portion of heart assembly with rail 9, and are located between two wing rails 5；It is described
Fork heart assembly 1 is by the leading portion 1 that is easily lost and is not easy the back segment 2 being lost and docks and be fixed as one from beginning to end by Flash Butt Welding, and
The leading portion 1 being easily lost is potassium steel forging molding, and being not easy the back segment 2 being lost is potassium steel casting and forming；The Flash Butt Welding
It is respectively equipped with through-hole 3 on the web of the rail of 7 two sides of weld seam fork apex of the heart rail 1-1, and is symmetrically arranged between two sides wing rail 5 at through-hole 3 suitable
The interval iron 4 matched, and be each passed through rail washer 8, interval iron by two bolt pairs 6), through-hole 3 and wing rail 5 will pitch apex of the heart rail
The rear end 1-1 is connected and fixed with two sides wing rail 5 and is integrated.It is wide that the weld seam 7 of the Flash Butt Welding is located at the fork rear end apex of the heart rail 1-1 rail head
Degree is on the section of 60~100mm.
The present invention pitches the leading portion and be not easy to dock from beginning to end after the back segment being lost is separately fabricated and pass through sudden strain of a muscle that heart assembly is easily lost
Photocoagulation is fixed as one, and the fork heart is easily lost position and is replaced with forging potassium steel, remaining position is replaced with potassium steel, with entirety
The forging potassium steel fork heart is compared, and can be reduced by 40% forging potassium steel dosage, be reduced fork heart forging difficulty and production cost, improve
Forging potassium steel pitches interior portion quality, fork heart forging potassium steel and casting high manganese steel material performance is given full play to, to extend
Whole group railway frog service life.In addition, by bolt pair, rail washer by interval iron (clamping plate) and weld seam two sides pitch the heart and wing rail into
After row reinforces installation, ensure that safety in utilization, while railway frog upper track is on active service, interval iron (clamping plate) is by heart rail load transmission to the wing
Rail optimizes the force structure of heart rail, improves the service life of the railway frog fork heart.
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.
