Summary of the invention
Purpose of design: design a kind of by the heart rail of wheel transition region, wing rail are used mechanical performance than potassium steel more
Excellent alloy steel mosaic block, promotes heart rail, the shock resistance of wing rail and anti-wear performance further, makes heart rail, wing rail life-span be prolonged
Long, solve embedded combined high manganese steel frog wheel transition region heart rail wing rail premature failure, thus improve whole group of railway frog
Service life.
Design: in order to realize above-mentioned purpose of design, the present invention, on structure designs, designs a kind of embedded alloy steel core
The embedded combined high manganese steel frog of rail wing rail, is shown in Fig. 1.Railway frog is pitched the heart, wing rail, fork with rail and the heart rail wing by embedded potassium steel
Rail alloy steel mosaic block is assembled by high-strength bolt auxiliary connection, rail packing ring and interval iron.Fork heart main body uses potassium steel
Casting, wheel tread uses explosion hardening technique pre-hardening.Fork heart wheel transition region heart rail, wing rail mosaic block use mechanical performance
The steel alloy manufacture more excellent than potassium steel, and be assembled into one with fork heart main body by high-strength bolt auxiliary connection.Fork is with rail and the wing
Rail uses heat-treated rail to make.Two wing rails of assembled frog are positioned at the both sides of the manganese fork heart, are bolted pair and rail
Two wing rails and manganese are pitched the heart and are connected and fixed by packing ring；Two forks of assembled frog are arranged on the two of manganese fork heart afterbody with rail
Side, and between two wing rails, and be bolted pair, rail packing ring and general interval ferrum three is fastened on one
Rise.When railway frog wheel transition region heart rail needs to change because of trauma, it is only necessary to changing alloy steel mosaic block, railway frog main body can continue
Continuous use.Due to alloy steel mosaic block lighter weight, on-the-spot replacing is easy to maintenance.Alloy steel mosaic block simple in construction, volume is little,
Processing and manufacturing cost is relatively low, has significant low-cost advantage relative to changing whole group of railway frog.
Technical scheme: the embedded combined high manganese steel frog of a kind of embedded alloy steel core rail wing rail, embedded combination Gao Meng
Steel railway frog by the embedded potassium steel fork heart, wing rail, fork with rail and heart rail wing rail alloy steel mosaic block by high-strength bolt auxiliary connection,
Rail packing ring and interval iron assemble, and the embedded potassium steel fork heart uses composite unit structure and embedded potassium steel fork heart main body
Using casting potassium steel, wheel tread uses blast pre-hardening；Embedded potassium steel fork the heart rail of the heart, wing rail and with fork with rail fill
The interval iron joined uses one piece casting, the wheel mistake between the theoretical point of the embedded potassium steel fork heart to heart rail width 60mm section
Crossing district is boxed frame structure, its bottom lock, open-top.
The present invention is compared with background technology, and one is compared with the pure manganese steel fork heart, pitches heart heart wing rail impact resistance, anti-wear performance
Significantly improve；Two is alloy steel mosaic block lighter weight, and on-the-spot replacing is easy to maintenance；Three is alloy steel mosaic block simple in construction,
Volume is little, and processing and manufacturing cost is relatively low；Four is to have significant low-cost advantage relative to whole group of railway frog of replacing.
