Abstract
A forge welding frog in railway is characterized in that a forge welding frog of same material with the steel orbit of railway comprises a heart orbit and a wing orbit, wherein, the heart orbit comprises a frog heart, a first half heart orbit, a second half heart orbit. The frog heart is divided into a peak end, a middle portion and a root portion, wherein, the connection portion between the middle portion and the second half heart orbit is an arc structure. A standard orbit head of the root portion is connected with the first half heart orbit. A convex plat is arranged in the wais of the standard orbit head. The convex plat is connected with the second half heart orbit. The heart orbit is fixed with the wing orbit by a separation iron. The heart orbit is connected with the frog heart into a whole. The utility model has the advantages of high intensity, easy forge mould, no planning difficulty, easy assembly and long life span. A structure shaped like Chinese character 'shi' is removed off. The separation iron bolt is directly connected with advantages of low cost, simple structure and easy batch production.
Description
Technical field
The utility model relates to a kind of railway smithwelding railway frog.
Background technology
Railway generally adopts solid manganese steel frog at present, because there is the internal flaw of casting in high manganese steel frog, causes the overwhelming majority damaged before not reaching the limit of wear prerequisite, can not satisfy the needs of transregional overlength gapless track of China railways speed-raising development.Chinese patent CN2302284 discloses a kind of " railway smithwelding railway frog " its architectural feature and is for this reason, the welding of the full section of the fork heart and heart rail face, fork heart heart rail and wing rail welding, fork heart cross section is " scholar " shape, it has overcome the deficiencies in the prior art, but unsatisfactory part is arranged still, because its fork heart must forge " scholar " word shape, so that the wing rail welding, and be full section welding, the fork heart is connected difficulty with heart rail, forge difficulty, weld seam is difficult for normalizing, and complex-shaped difficult processing is unfavorable for producing in enormous quantities.
Summary of the invention
The purpose of this utility model provides a kind of fork heart that will forge, heart rail and wing rail and is connected to become an overall structure, and heart rail and wing rail are by the bolted railway smithwelding of interval iron railway frog, in order to overcome disadvantages of background technology.
In order to realize the foregoing invention purpose, the utility model adopts following technical proposals: heart rail, the wing rail be made up of the fork heart, the first half of heart rail, the second half of heart rail with the smithwelding railway frog of material with railway track constitute, the fork heart is divided into point, middle part and root, the middle part is an arcuate structure with the second half of heart rail junction, root forges the standard rail head and is connected with the first half of heart rail, heart rail connects as one with the fork heart, the web of the rail portion of standard rail head is provided with a boss, boss matches with the second half of heart rail and is connected, and fixedlys connected by interval iron between heart rail and the wing rail.
Since adopted said structure, the utility model intensity height, and forging molding is easy, does not have to dig and mills difficulty, and is easy to assembly, long service life.Owing to removed " soil " word structure, directly used with material interval iron bolt to connect or welding, so price is low.And can transmit the gapless track TEMPERATURE FORCE, can with the circuit rail welding, railway frog needn't be frequently changed in also soldering on the line.Simple in structure, be easy to produce in batches.

The specific embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Fig. 1 is overall structure embodiment of the present utility model.Form with heart rail, wing rail 1,2 that railway track is made up of the fork heart 3, first half of heart rail 5, the second half of heart rail 6 with the smithwelding railway frog of material, the fork heart 3 is divided into point, middle part and root.In conjunction with Fig. 1, Fig. 2, middle part and the second half of heart rail, 6 junctions are arc 8 structures, and root forges standard rail head 10.The fork heart 3 and first half of heart rail 5, the second half of heart rail 6 connect as one, standard rail head 10 is connected with the first half of heart rail 5, a boss 9 forges in the web of the rail portion of standard rail head 10, boss 9 matches with the second half of heart rail, 6 web of the rail places and is connected, the boss 9 of standard rail head 10 is provided with bolt hole 11, is provided with interval iron 4 between heart rail 5,6 and the wing rail 1,2 and is used for bolt and is connected or welds.If bolt connects, from the bolt hole 11 of boss 9, interval iron 4, pass bolt fixing.If welding is directly welded first half of heart rail 5, the second half of heart rail 6 fixing.As Fig. 4,5,6, boss 9 also can forge in addition with first half of heart rail 5, second half of heart rail 6 webs of the rail 12 and match, and connects or welding with bolt.
In forging process, rail head directly forms prong work edge of table with 1: 5 the gradient; The flange of rail is identical with the smithwelding railway frog.The root of the fork heart directly forges the standard rail head 10 that is connected with rail, and full section one saves rail and forms the first half of heart rail 5 burn-oning, and is connected with bolt or welds at arcus part with the second half of heart rail 6.When the fork heart that fuses, heart rail and wing rail were assembled, each position all connected or welding with the interval iron bolt, the same material of interval iron and rail.
Claims (3)
1, a kind of railway smithwelding railway frog, it is characterized in that, heart rail, the wing rail be made up of the fork heart, the first half of heart rail, the second half of heart rail with the smithwelding railway frog of material with railway track constitute, the fork heart is divided into point, middle part and root, the middle part is an arcuate structure with the second half of heart rail junction, root forges the standard rail head and is connected with the first half of heart rail, the web of the rail portion of standard rail head is provided with a boss, boss matches with the second half of heart rail and is connected, fixedly connected by interval iron between heart rail and the wing rail, heart rail connects as one with the fork heart.
