Description
Technical field
The utility model relates to railway traffic equipment, especially a kind of track line switch area frog structure.
Background technique
Track switch is the line connection equipment that rolling stock was transferred to or crossed another station track from a station track, is the weight of track structure
Want component part.Currently, applying in railway and urban track traffic at most is common single turnout, it is by railway switch, connection
Partially, three unit compositions of railway frog and guard rail.Railway frog is the equipment for instigating wheel to cross another strand of rail by one rail, by pitching
The heart, wing rail and union piece composition, are divided by structural type: having two class of stiff frog and swing nose crossing.Stiff frog is come
It says, from throat of frog to the distance for having one section of path to interrupt the practical tip of heart rail, here it is the idle spaces of track switch.Wheel
By herein when, it is possible to cause to derail because going to the wrong way frog flangeway, and to also limit train logical for the presence of this idle space
The speed of turnout passing, it is very unfavorable to bullet train is started.
In order to eliminate idle space, movable center points structure, which has been developed, to be come out, and most important feature is exactly railway frog
Heart rail can be dynamic with plate.When we will open a direction station track, the central body of frog of movable point frogs just with to open direction consistent
Wing rail is closely connected, separates with another wing rail, and so, the idle space of common track switch is just not present.Although movable head track
Trouble has eliminated the idle space of track switch, driving more it is steady pleasantly, switch crossing speed limitation is smaller.But it still there are it is some not
Foot, on the one hand, movable center points are composed of parts such as wing rail, long heart rail, short heart rail, fork tip of a root rails, and ratio is constructed
It is more complex therefore particularly inconvenient in processing and laying；On the other hand, central body of frog and wing rail are two mutually independent portions
Point, only when opening a direction station track, just meeting is closely connected together for the two, therefore the globality of the transition region is poor.Work as vehicle
When passing through, Wheel Rail Contact area can change wheel suddenly, form stress and concentrate, at the same also with the mutation of stress with it is traversing.
This just inevitably causes centainly to damage to heart rail type face, and the serious service life for reducing heart rail improves railway switch area
Maintenance cost.
Summary of the invention
The purpose of this utility model is just to provide that a kind of structure is simple, the manufacture cost of overhaul is low, laying easy to process, can have
Effect solves the problems, such as existing stiff frog, and there are idle space and the movable-point crossing railway line ways that structure is complicated, the service life is low
Trouble area's frog structure.
The track line switch area frog structure of the utility model, which is characterized in that the rail of railway frog section is divided into railway frog
Straight rail and railway frog bend, and the two all has and connect straight rail, the identical rail head cross-section of connection bend, swing nose crossing two with stock rail
At the rail gap at end, using concrete wide crosstie, the width of concrete wide crosstie is 1.5-2.5 times of regular sleeper, to increase bearing surface
Product reduces the deformation at rail joint and Ballast stress；Concrete wide crosstie and regular sleeper middle part surface peace within the scope of railway frog
Ball slide plate is filled, railway frog bottom plate is placed on ball slide plate, the two sides setting gag lever post of railway frog bottom plate, and the two of railway frog bottom plate
End is stuck in limit buckle, and limit buckle is fixed on concrete wide crosstie, and to limit the vertical and length travel of railway frog bottom plate, railway frog is straight
Rail, railway frog bend are fixed on railway frog bottom plate；Switch machine is connected by drive rod traction piece with railway frog bottom plate, and railway frog bottom is controlled
Plate moves left and right switching station track.
The working principle of the track line switch area frog structure of the utility model is, when rolling stock will be from song to station track
When being transferred to straight track, the mobile swing nose crossing position of manipulation switch machine makes railway frog straight rail become with the railhead part for connecting straight rail
In being completely coincident, railway frog bend is separated with connection bend.At this point, the right side edge of swing nose crossing bottom plate is just close with gag lever post
Patch, left side edge are separated with gag lever post, and such swing nose crossing is just in the common work of gag lever post, limit buckle and drive rod traction piece
Lock operation is realized under, has finally opened straight track, is closed bent to station track.When rolling stock will turn from straight track
Enter it is bent to station track when, the mobile swing nose crossing position of manipulation switch machine tends to railway frog bend with the railhead part for connecting bend
It being completely coincident, railway frog straight rail is separated with connection straight rail, at this point, the left side edge of swing nose crossing bottom plate is just closely connected with gag lever post,
Right side edge is separated with gag lever post, and such swing nose crossing is just in the collective effect of gag lever post, limit buckle and drive rod traction piece
Under realize lock operation, finally opened song to station track, close straight track.
The track line switch area frog structure of the utility model replaces former No. 12 track switch railway frogs using novel frog construction
Toe can preferably solve a series of present in stiff frog and movable-point crossing lack away to the part between railway frog heel distance
It falls into, the relatively easy, laying easy to process with structure, steel-rail structure performance is good, stress damage is small, and rail maintenance is easy to change etc.
Advantage.
