It is relatively not conllinear two-by-two to set.When wheel passes through railway frog, first the connection rail 20 from fork heart side passes through the fork heart, then drives to fork
On the connection rail 20 of heart opposite side, so as to fulfill the lane change of locomotive.
As shown in Figure 1, in embodiment one, pitch the heart 10 and four connection rails 20 form X-shaped structure.Wheels travel is this
In X-shaped structure, travel route can be varied as desired in, realizes the lane change of locomotive.
In embodiment one, as depicted in figs. 1 and 2, connect and the first groove structure is offered on rail 20, pitch and opened up on the heart 10
There is the second groove structure being connected with the first groove structure.Connected by the first groove structure and the second groove structure, guiding
Wheel, again to rail 20 is connected, completes the lane change process of locomotive from connection rail 20 to the fork heart 10.
Optionally, connection rail 20 includes the sequentially connected flange of rail, the web of the rail and rail head, and the flange of rail is used to be fixed at ground
On.It is fixedly connected with the ground by the flange of rail, it is ensured that locomotive driving connection rail 20 when connecting on rail 20 will not rock, it is ensured that driving
Safety.Optionally, land-fill method can be also used, by flange of rail landfill and ground.
Railway frog is arranged in pairs, that is, is connected rail 20 also to be arranged in pairs, be arranged in pairs in correspondence on the web of the rail of connection rail 20 and open
Equipped with mounting hole, mounting hole is multiple, and the corresponding mounting hole opened up is used for attaching plate elements, to keep the connection rail 20 being arranged in pairs
Gauge.The utility model additionally provides two (not shown) of embodiment of railway frog, including the fork heart 10 and the end with pitching the heart 10
The connection rail 20 of head connection.Difference lies in the fork heart 10 in embodiment two is overall by resistance to break-in with embodiment one for embodiment two
Jin Gang is made.Identical with embodiment one, by the fork heart of antifriction alloy steel making, its wearability is higher than existing high manganese steel frog,
High manganese steel frog thus can be replaced, extensive use on the railroad track；And compared to the fork heart 10 in embodiment one, by wear-resisting
The fork heart 10 of steel alloy monoblock cast, further increases the wear-resisting property of the fork heart 10, so as to extend the use longevity of the fork heart 10
Life.
Optionally, the hardness of the heart 10 is pitched between 370HBW~430HBW.Overall because of the fork heart is made of wear-resisting alloy steel,
Thus, the fork heart has high intensity, high tenacity.
Identical with embodiment one, the connection rail 20 in embodiment two is also formed by U75V rail.It is subject to due to connection rail
Impact force is smaller relative to the fork heart, thus can meet requirement using existing potassium steel rail.Optionally, embodiment two
In connection rail be also U75V rail.
Optionally, pitch and welded between the termination of the heart 10 and connection rail 20 by flash welding.Flash welding is electric current by two
The contact surface of workpiece, the resistance of its tiny contact point and its electric arc generation heat for contacting surface are docked, by butting surface
Heating, in due course between after, butt joint applies pressure, makes the whole regions of the two butting surfaces electricity that gets up of strong bonded at the same time
Welding resistance method.In embodiment one, by flash welding, the fork heart 10 can be connected firmly with being connected rail 20, and shape is integral.
Identical with embodiment one, in embodiment two, the termination of the fork heart 10 is four, and four terminations are relatively common two-by-two respectively
Line is set, and it is also four accordingly to connect rail 20, and four terminations are connected to a connection rail 20, four connection rails 20
It is relatively conllinear two-by-two respectively to set.When wheel passes through railway frog, first the connection rail 20 from fork heart side passes through the fork heart, then drives to
On the connection rail 20 for pitching heart opposite side, so as to fulfill the lane change of locomotive.
It is identical with embodiment one, in embodiment two, pitch the heart 10 and four connection rails 20 form X-shaped structure.Wheels travel exists
In this X-shaped structure, travel route can be varied as desired in, realizes the lane change of locomotive.
Optionally, connect and the first groove structure is offered on rail 20, offer on the fork heart 10 and be connected with the first groove structure
The second logical groove structure.Connected by the first groove structure and the second groove structure, guiding wheel is from connection rail 20 to the fork heart
10 arrive connection rail 20 again, complete the lane change process of locomotive.
Identical with embodiment one, the connection rail 20 in embodiment two also includes the sequentially connected flange of rail, the web of the rail and rail head, rail
Bottom is used to be fixedly installed on the ground.It is fixedly connected with the ground by the flange of rail, it is ensured that locomotive driving is connected when connecting on rail 20
Rail 20 will not rock, it is ensured that traffic safety.Optionally, land-fill method can be also used, by flange of rail landfill and ground.
Railway frog is arranged in pairs, that is, is connected rail 20 also to be arranged in pairs, be arranged in pairs in correspondence on the web of the rail of connection rail 20 and open
Equipped with mounting hole, mounting hole is multiple, and the corresponding mounting hole opened up is used for attaching plate elements, to keep the connection rail 20 being arranged in pairs
Gauge.
It can be seen from the above description that the above embodiments of the present invention achieve the following technical effects：
At least top of the fork heart 10 is made of wear-resisting alloy steel.It is high using the fork heart of antifriction alloy steel making, its wearability
In existing high manganese steel frog, the service life of the fork heart can be extended, thus high manganese steel frog can be replaced, on the railroad track
Extensive use.
Alloy steel construction track switch in the mill, it is necessary to using unlike material welding, the welding skill of medium alloy steel of the present invention
Art, can be successfully applied on railway steel alloy welded frog, and welding technique is ripe.The technology tramcar field is at home
It is pioneering, through Mechanics Performance Testing and flaw detection, meet product quality requirement.
For tramcar due to being limited by existing highway, crossing angle and condition are different, cause diamond crossing angle and
Radius is varied, such as uses potassium steel block cast form, mould species is various, with high costs, and the process-cycle is longer.Therefore in water chestnut
Shape preferably uses alloy steel frog form in intersecting, to adapt to various crossing angle requirements.Steel alloy have high intensity, high tenacity,
The good characteristics such as high-wearing feature, select steel alloy to be selected as tramcar track switch railway frog material for the mainstream in market.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the present invention, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on, should be included within the scope of protection of this utility model.
