Description
Technical Field
The application relates to the technical field of rail transit, in particular to a cross-rail combined steel rail.
Background
A switch is a device for switching a train from one set of rails to another, most commonly a conventional single switch, which, for example, as shown in fig. 1, is generally composed of three units, a switch, a connecting part, a frog and a guard rail, the switch unit including a stock rail and a point rail; the frog and guard rail unit comprises a point rail, a wing rail and a guard rail.
In the prior art, the stock rail and the point rail are usually the same grade of different steel rail, and the wing rail and the center rail are also the same grade of different steel rail. For example, 50kg/m steel rail single turnout is used as a stock rail or a wing rail, and a point rail or a point rail is also matched with a 50kg grade 50AT1 steel rail correspondingly; for another example, 60kg/m rail single turnout uses 60kg/m rail or 60TY1 rail as wing rail or stock rail, and the point rail or switch rail must also adopt 60kg grade 60AT1 or 60AT2 rail matching design method.
However, since the wing rail and the point rail or the stock rail and the point rail use the same grade of different steel rails and have a height difference therebetween, a slider bed needs to be arranged below the point rail or the point rail when the wing rail and the point rail or the stock rail and the point rail are matched with each other, as shown in fig. 2. In addition, because there is the difference in height between wing rail and the point rail or between stock rail and the switch rail, still need to carry out the die mould heat treatment AT the point of connection of point rail or switch rail and ordinary circuit rail, like the 50AT1 rail type of left end in figure 3, through the forging and pressing changeover portion of L 'section, forge and press into the forging and pressing shaping section of right-hand member L section for the height of the L section's of rail after the forging and pressing shaping risees, thereby can match the butt joint with 50kg/m rail, realize the connection of switch rail and circuit rail. However, the profiling heat treatment not only causes the processing procedure to be complicated, but also causes a heat affected zone at the rail heel end if the profiling heat treatment process is normally operated, and causes problems such as abnormal structure and hot processing defects at the rail heel end if the profiling heat treatment process is abnormally operated.
In summary, it is known that, because the rails at the points in the prior art have the above-mentioned disadvantages, how to provide a better combined rail, so as to eliminate the height difference between the wing rail and the point rail or between the stock rail and the tongue rail, is a problem to be solved in the art.
SUMMERY OF THE UTILITY MODEL
In view of this, the present invention provides a cross rail type combined steel rail, so that the height difference between the wing rail and the point rail or between the stock rail and the tongue rail can be eliminated.
The technical scheme of the utility model specifically be so realized:
a cross-rail type combined steel rail comprises: the steel plate comprises an iron base plate, at least one first steel rail and at least one second steel rail; the first steel rail and the second steel rail are both arranged at preset positions on the iron base plate, and the second steel rail is positioned on the inner side of the first steel rail; the shape of the first steel rail is 50m/kg steel rail; the shape of the second steel rail is a 60AT1 steel rail.

Detailed Description
In order to make the technical solution and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 4 to 6, the utility model provides a cross rail type combined steel rail, include: the steel rail comprises an iron base plate 5, at least one first steel rail and at least one second steel rail;
the first steel rail and the second steel rail are both arranged at preset positions on the iron base plate 5, and the second steel rail is positioned on the inner side of the first steel rail;
the shape of the first steel rail is 50m/kg steel rail;
the shape of the second steel rail is a 60AT1 steel rail.
Because the height of 50m/kg rail is the same with 60AT1 rail, through making up 50m/kg rail and 60AT1 rail, set up to the combination rail of cross rail type, thereby can eliminate the difference in height between first rail and the second rail, can directly set up first rail and second rail on the iron tie plate, need not to set up the slide bed platform in the below of second rail, and then reduce spare part quantity, make overall structure simple, easily installation, and reduced the slide bed platform and be connected with the iron tie plate and vibration and noise that come.
In the technical scheme of the utility model, can use multiple implementation method to realize foretell cross rail type combination rail. The technical solution of the present invention will be described in detail below by taking several implementation modes as examples.
For example, preferably, in one embodiment of the present invention, as shown in fig. 4, the first rail may be a stock rail 1 and the second rail may be a point rail 2.
Preferably, by way of example, there may be two stock rails and two point rails, wherein the two point rails are respectively arranged on the inner sides of the two stock rails.
The utility model discloses an in the embodiment, when first rail is the stock rail, the second rail is the switch rail, the rail type of stock rail is 50m/kg rail, and the rail type of switch rail is 60AT1 rail, because the height of 50m/kg rail and 60AT1 rail is the same, so can directly set up stock rail 1 and switch rail 2 on iron tie plate 5, need not to set up the slide bed platform again in the bottom of switch rail 2.
For another example, in an embodiment of the present invention, as shown in fig. 5, the first rail may be a wing rail 3, and the second rail may be a point rail 4.
Preferably, as an example, there may be two wing rails, and there may be two point rails, and the two point rails are respectively disposed inside the two wing rails.
The utility model discloses an in the embodiment, when first rail is the wing rail, when the second rail is the heart rail, the rail type of wing rail is 50m/kg rail, and the rail type of heart rail is 60AT1 rail, because the height of 50m/kg rail and 60AT1 rail is the same, so can directly set up wing rail 3 and heart rail 4 on iron tie plate 5, need not to set up the sliding bed platform again in the bottom of heart rail 4.
