CN102021866A, title " alloy steel combined frog in wedge-shaped structure ", the two side of the web of the rail of its alloy steel core rail
It is lower end to the tilted inclined-plane I of the web of the rail, makes the approximate wedge shape of cross sectional shape of the web of the rail, the inner face of wedge-shaped interval iron is and inclined-plane
The inclined-plane II of I fitting;Two wing rails are symmetrically positioned in the both sides of alloy steel core rail, and two wedge-shaped interval irons are symmetrically positioned in wing rail with closing
Between golden steel core rail, and wedge-shaped interval iron outer face is bonded with the web of the rail sidewall shape of wing rail, inclined-plane II and the inclined-plane I of inner face
It is closely connected, it is bolted secondary and rail packing ring and is fastened on two wing rails, two wedge-shaped interval irons and alloy steel core rail
Together;Two both sides for pitching the afterbody that alloy steel core rail is symmetricly set on rail, and between two wing rails, and pass through bolt
Three is connected and fixed by auxiliary connection, rail packing ring and general interval iron.The utility model passes through wedge-shaped alloy steel core rail
With being used cooperatively for wedge-shaped interval iron, solve 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, enhancing
The resistance to overturning of railway frog, improve the service life of whole group railway frog.
CN204491321U, title " forging potassium steel heart rail assembled frog ", its heart rail is using forging high manganese steel material system
Into pitching and use the burning optimization on line rail with existing line phase same material to be made with rail and wing rail.The web of the rail section of the heart rail
The approximate wedge shape of shape, two wing rails are symmetrically positioned in the both sides of heart rail, and two wedge-shaped interval irons are symmetrically positioned between wing rail and heart rail,
It is bolted secondary and rail packing ring two wing rails, two wedge-shaped interval irons and heart rail are connected and fixed；Two forks
Be symmetricly set on the both sides of the afterbody of heart rail with rail, and between two wing rails, and be bolted secondary, rail packing ring and
Three is connected and fixed by general interval iron.The utility model strengthens rut using the excellent impact flexibility of potassium steel is forged
Pitch impact resistance；Solderability using fork with rail and wing rail, to meet the gapless track market demand；And prevented by wedge structure
The vibration up and down of heart rail, strengthen the resistance to overturning of assembled frog, improve the service life of whole group railway frog.
Above-mentioned background technology CN204311302U refers to a kind of wing rail continous way frog structure, prevents fork with rail and the heart
The method that relative displacement occurs for rail is that fork is integrally formed with rail and wing rail.CN102021866A and CN102021866A all refer to one
Kind fork heart heart rail web of the rail section is wedge structure, it is therefore an objective to solves the changing of the relative positions up and down of resolution rail and wing rail.And in fixed combined type
When railway frog is used for gapless track, in the railroad section that the temperature difference is larger, in the case where TEMPERATURE FORCE acts on, there occurs larger with rail for the fork heart and fork
Relative displacement, serious can be such that the fork heart is cut with fork with the connecting bolt of rail.The fork heart uses overall swallow with fork with rail
Stern construction and the design of local wedge structure, by interference fit, increase frictional resistance between the two, improve it in outer masterpiece
With it is lower generation relative displacement resistivity, so as to improve railway frog service life.
Utility model content
Purpose of design：The problem of relative displacement occurs under TEMPERATURE FORCE effect with rail with fork for the assembled frog fork heart, if
Count a kind of assembling structure of new fork heart with fork with rail, by increasing the fork heart and fork with the frictional resistance between rail, prevent fork with
Relative displacement occurs because TEMPERATURE FORCE acts on for rail, further improves the resistance to overturning and security of assembled frog structure, to meet
Assembling structure of the assembled frog fork heart of gapless track requirement with fork with rail.
Design：The cause of design：Assembled frog is generally passed through high-strength using the fork heart, wing rail, fork with three big part of rail
The structure that bolt and interval iron are assembled into one.The cooperation pitched with rail and the fork heart generally uses the upper lower inclined plane in rail fish tail space
Or lower inclined plane and the closely connected structure design of web of the rail circular arc., can not in actual production due to being influenceed by machining accuracy and assembly technology
Ensure that mating surface is completely closely connected, even if being closely connected between mating surface, because the frictional resistance between mating surface is mainly by bolt pair
There is provided, in the gapless track section that the temperature difference is larger, pitch with the frictional force suffered by rail be less than its suffered by TEMPERATURE FORCE, cause pitch the heart with
The relative displacement with rail generally existing longitudinal direction is pitched, the big circuit of the temperature difference there is also the fork heart and cut with fork with rail bolt often
Phenomenon, have a strong impact on traffic safety and railway frog service life.Therefore, the utility model is in structure design, the application demand
Be pitch heart heel end with two fork with the dovetail assembling structure of rail and every fork with rail and fork the heart longitudinally, laterally wedge structure set
Meter, and assembled using this structure and by interference fit, by increasing the fork heart and fork with the frictional resistance between rail, prevent
Only longitudinally opposite displacement therebetween, so as to improve the resistance to overturning of assembled frog and operation safety.Its combination rut
Fork is assembled by the fork heart, wing rail, fork with rail by high-strength bolt.Fork pericardium includes the heart wing rail monoblock type fork heart and heart wing rail split
Formula pitches the heart；Fork heart heel end is connected as one with rail with two forks using dovetail assembling structure by high-strength bolt auxiliary connection；Every
The fish tail space pitched with rail and the fork heart use vertical and horizontal wedge structure, and is assembled by interference fit, increase pitch with
The frictional resistance of rail longitudinal direction, and then the relative displacement for making fork occur with rail under TEMPERATURE FORCE effect is effectively controlled.
Technical scheme：A kind of assembling structure of assembled frog fork heart with fork with rail, pitches heart heel end and two forks use with rail
Dovetail assembling structure, and every fork uses vertical and horizontal wedge structure with the fish tail space ramp of rail and fork heart heel end.
The utility model is compared with background technology, first, the program is simple in construction, manufacture easy to process；Second, solves fork
The problem of relative displacement occurs with the fork heart with rail；Third, assembled frog disclosure satisfy that circuit seamless process requirement；Fourth, improve group
Rhythmic fork overall structure stability, security and service life.
