Abstract

A kind of rail parts comprise a rail head, the web part at a rail chair and a middle part, and this rail head has the engagement groove of wheel thread that a formation departs from the rail centerline at an upper portion thereof.This rail can be cemented in the groove of circuit with a kind of flexible perfusion ploydiaphragm object, to constitute the track of electric car or other similar vehicles.

Description

Improved railroad vehicle track
The present invention relates to a kind of rail parts, particularly (but being not limited to) and relate to the rail parts that are used for electric car, rolling stock or similar vehicles.
So far the track steel rolling of this railroad vehicle, this is a kind of continuous roll off process of complexity, because described track adopts this form, enough intensity, abrasion resistance and being connected have in the line been guaranteed, it should be noted that this rail has independently opening portion and adjacent part, they are positioned on the track of load-bearing transportation device.
The purpose of this invention is to provide a kind of improved, rail parts of being used for electric car, rolling stock or similar vehicles.
From an aspect, rail parts provided by the invention comprise a rail head, a rail chair and a middle pectoral plate part, and this rail head has a wheel rim engaging groove, and this wheel rim engaging groove formation departs from the rail centerline at an upper portion thereof.
Preferably this groove is positioned on the rail head part of described center line one side fully, and perhaps the major part of groove is so to be provided with, and the degree of depth of groove can approximate the thickness of the rail head part of supporting wheel greatly.
The section bar of this rail is transverse bending at an easy rate.
According to rail of the present invention, in can fixed at an easy rate groove on the line, or in the fluting on the road, the top of fluting is positioned on the position with the road surface equal height, perhaps great majority are so, use elastomeric material by the perfusion of the mixture of for example polymer class to carry out fixedly can reaching good effect.The wheel mate of described rail head can protrude from road surface a little, and this part is positioned at an other side of the groove of equal height.
Rail can flexibly be bearing in groove/otch on the road, because the elasticity of linkage itself has difference, so rail is supported on the member of specially appointed a kind of flexible fastening piece.
For a more complete understanding of the present invention, now embodiment is illustrated, wherein is described below with the example that has with reference to the accompanying drawings:
Fig. 1 has represented a cross section of rail, and rail is installed in the groove in the road, and this circuit can be the main line of a part, mine track or stock ground track;
Each accompanying drawing of Fig. 2 to Fig. 6 has been represented the different cross-sections of the rail, and these sections can be a kind of application of the profile among Fig. 1 ,-notice that the upper surface of the rail head among Fig. 6 is downward-sloping, to avoid " packing tightly " rail, such gradient often is needs.
Refer now to Fig. 1, rail chair 1 is symmetrical, and web 2 to resemble the rail head be asymmetric, particularly wheel rim engaging groove 3 is to constitute like this in rail head, it is the rail head part that its whole or major part is positioned at center line one side, therefore in part 4, need a large amount of metals, the wheel mate 5 of rail head to be positioned on the slightly high plane of the other side than groove.
This rail is supported in a groove or the otch at the beginning, perhaps otherwise constitutes, and for example one is cemented in the circuit 6, and it is certain powder that solidifies of perfusion, and compacting enters moisture or moisture content with defence.Advantageously, a resilient sleeper-bearing 7 can be inserted in the bottom of this groove, and extends along the direction of groove.Flexible voussoir or distribute with supporting rail along compartment of terrain on the slot length by the member (not shown) that general distance is provided with, then around side and a kind of elastomeric material of forming by mixture of polymers or cementing agent of following cast of rail, and make it to fixedly positioning, in fact voussoir can be made by some composite materials 8, for example can be Yi Kesaite (Icoset), dust earthworm (Edilon) and this card (Sika).
The result that the track of electric car is laid in this way demonstrates than other system that is adopted so far and has reduced noise widely, has reduced the vibration on ground simultaneously.In addition, water can not enter railway roadbed at an easy rate yet, because it seals fully.The expense of this device is also low than similar system, and for the slinging and changing of orbital segment, has not simplified owing to backing plate 7 is not connected on the fixed rail chair.In addition, because rail is isolated in " shell ", spuious electric current leaks (in the electric system) degree that also minimizes.
Be typically, this rail itself can be formed by a joint rectangle steel billet roll off, this rectangle steel billet is drawn from a roughing mill, and have a web breach of partial plastic forming, in an accurately machined switchable milling train, process then, in first pass of this double-roller type milling train, use stricter method to be shaped the web breach.The steel billet half-twist can be shaped the groove 2 in rail head in roughing in second (switchable) pass then, fully is shaped in roll off subsequently then.Importantly, the rail section of partial plastic forming is turned round 90 ° again, so that web fully is shaped in the 4th pass, and can go back to 90 ° in the same way, so that groove 2 can be shaped in last roll off in finish rolling.
The simple roll off program that is adopted has been avoided the roll off program of the complexity of use so far, and has also avoided the arris roll.
The steel that uses can be the BS11 level usually, perhaps is equivalent to the UIC level, and many rail section weight standards are 87 kilograms/meter.Although it is 60 kilograms/meter that fewer rail section is arranged, also can easily adopt this technology manufacturing.
Though the indivedual embodiment among the present invention with reference to the accompanying drawings are described, can be interpreted as it the modification of multiple class at an easy rate, and run counter to effective range of the present invention.For example, other steel rolls parts, is exactly like this under the design of the track of the wheel operation of the adopting situation consistent with described principle.Slant edge 9 can be only in a side setting of the groove of circuit, perhaps all save, also can save backing plate 7.
