Between rail and alloy steel core rail, and wedge-shaped interval iron outer end face is bonded with the web of the rail sidewall shape of wing rail, the inclined-plane II of inner face
It is closely connected with inclined-plane I, secondary and rail washer is bolted and connects two wing rails, two wedge-shaped interval irons and alloy steel core rail
It is fixed together；Two are pitched the two sides for being symmetricly set on the tail portion of alloy steel core rail with rail, and are located between two wing rails, and lead to
It crosses bolt connection pair, rail washer and general interval iron three is connected and fixed.The present invention passes through wedge-shaped alloy steel core
Rail is used cooperatively with wedge-shaped interval iron, solves the problems, such as between alloy steel combination frog heart rail and wing rail up and down with respect to the changing of the relative positions, increasing
The overall stability of strong railway frog, improves the service life of whole group railway frog.
201620584979.6, title " a kind of smithwelding combined type obtuse frog ", belongs to railway switch technical field, it by
Stock rail, the forging fork heart, heart rail, side rail, interval iron, bolt group, side's pad, anti-loose measure pad assembling composition；Its structure are as follows: heart rail is
Two symmetrical track relative symmetry settings, the angle after two heart rail combinations are 18 55 ', 29 ＂, two heart rail front end interception length
120mm is spent, the fork heart after forging is welded to the basal orbit front end of heart rail using flash welding connection；The heart rail is in whole knot
Be symmetrical arranged in structure, for two groups of heart rail rail points with respect to 286mm, stock rail and side rail setting angle are 161 4 ', 31 ＂, side rail with substantially
Flangeway distance between rail is 47mm；Side's pad is mounted in the web of the rail of side rail, the screw bolt passes of bolt group side rail, basic
Rail, heart rail, interval iron, stock rail, side rail, anti-loose measure pad by bolt group bolt fastening.
Background technique 1 is related to a kind of potassium steel fork heart assembled frog, and potassium steel pitches the heart (the one knot with wing rail mosaic block
Structure).Background technique 2 and 3 is related to a kind of alloy steel core rail assembled frog, is alloy steel core rail and fork with rail, wing rail, wing rail
Mosaic block is assembled by the interval ferropexy of different structure.But nothing is unable to satisfy for fixed solid manganese steel frog
Line requirements are stitched, although alloy steel combination frog solves the problems, such as gapless track site welding, but alloy steel core rail structure process
Complexity, manufacturing cycle are long.
Summary of the invention
Purpose of design: avoiding the shortcoming in background technique, designs a kind of by sharp using patch between long and short heart rail
Interval iron is arranged in structure, and reaches the bolted rigid frog for improving the position stress and improving railway frog.
Design scheme: in order to realize above-mentioned purpose of design.The present invention in structure design, mainly solves bolted rigid frog
Heart rail light section is eccentric, improves the stress of heart rail, so that railway frog service life is improved, by two symmetrical wing rails and bending angle
It is assembled by high-strength bolt to spend identical long heart rail, short heart rail, interval iron.Long and short heart rail bending angle is identical, be α/
2(α is railway frog angle), heart rail light section bias is avoided, batch micro operations are convenient for.And used between long and short heart rail and paste sharp structure,
And interval iron is set, the overall stability of enhancing structure improves the position stress；Two wing rail bending angles are identical,
For α (α is railway frog angle), railway frog flangeway improves the accuracy of manufacture of railway frog using formation is machined after assembling.
Technical solution 1: a kind of bolted rigid frog, bolted rigid frog are identical by two symmetrical wing rails and bending angle
Long heart rail, short heart rail and interval iron are assembled by high-strength bolt.
Technical solution 2: a kind of design method of bolted rigid frog, including railway frog, long heart rail and short heart rail bending angle
It is identical, it is α/2, and using the sharp structure of patch between long heart rail and short heart rail, and interval iron is set, wing rail one and wing rail two are curved
Dog-ear degree is identical, is α, and two wing rail bending angles are identical, is α, and railway frog flangeway is improved using formation is machined after assembling
The accuracy of manufacture of railway frog.
