Abstract

The utility model relates to a railroad rail, the end surface of which is in a talus framework, and the taluses of both ends of the steel rail parallel mutually and plumb to the bottom face of the rail. The connected surface of the two steel rails forms a talus which is vertical to the ground after the two steel rails are connected. The vehicle can transit from one rail onto another steadily while running in the rail and has less vibration and low noise. The kind of steel rail has the advantage of simple structure, easy use and installation, investment saving, and is worth being used extensively in the railroading.

Description

Railroad rail

The utility model is relevant with the structure of rail, more specifically says so about the architecture advances of railway track with rail.

The bigger vibration of total generation when China's train travels in orbit at present, the noise of train driving produces harmful effect to environment along the line.The generation of this vibration and noise was both relevant, also relevant with the laying structure of rail with planeness and train running speed that railway track is laid.When laying rail, consider the rising-heat contracting-cold of rail, the joining place of rail must leave certain interval.The railway track bridging mode that China is traditional all adopts the tack gap to be connected.The rail of Xian Jieing by this way, train wheels are when being connected point, and to have height to have low because of being connected point, and the wheel vibration of travelling in the above is bigger, and train passes through just produces very big noise along the line.The gap is big more, and the vibration of train is big more, and the noise of generation is also big more.

The purpose of this utility model is to provide a kind of rail of new end face structure, makes when wheel travels on this track, can reduce train vibration and driving noise.

According to present this track structure, as shown in Figure 1, A is the contact point of wheel surface and first rail bar end, C is the contact site of wheel surface and second rail bar end points, B is that wheel surface falls into the position in the gap, on wheel surface, is in perpendicular to wheel circumference, and be to fall into the gap simultaneously by each point on the B point straight line, lose the support of rail.So wheel moves on this rail, its surperficial same position is in mode of the same race, and simultaneously by the gap point, this vibration of wheel is inevitable.

Solution of the present invention is to replace existing flat champignon rail with the rail that two end faces are ramp structure, and the inclined-plane at rail two ends is parallel to each other and perpendicular to the bottom surface of rail.With the track that this rail is connected, the interface between two one steel rails, be a inclined-plane perpendicular to ground.

For progressive of the present utility model is described, with an example the utility model design feature is described further in conjunction with the accompanying drawings more below.

Fig. 1 uses schematic diagram for existing railway track structure:

Fig. 2 is that the utility model inclined-plane rail is connected perspective view.

As shown in Figure 2, two one steel rails are connected mutually with the inclined-plane, and the angle of slope on inclined-plane is 45 °, and E-F represents the contact surface of wheel on rail among the figure.As can be seen from the figure, wheel rolls to rail (2) from rail (1), when the E of wheel end begins to press the rail (2) of rail, the major part of wheel still is on the rail (1), and along with wheel rolls forward, pressure wheel is fewer and feweri in the part of rail (1), constantly increase and be pressed onto rail (2) part, arrive G-H position wheel the pressure of two one steel rails is equated, when arriving E '-F ' position, the major part of wheel has then changed rail (2) over to.Whole in a word wheel rolls when another one steel rail from an one steel rail, is in a kind of smooth transition process of balancing in power all the time, can not go out the section that exists in the phenomenon prior art, so vehicle operational shock on this track is little, noise is low.

The utility model has the advantages that clearly. This rail project organization is simple, easy to install and use, can effectively reduce vibration and the noise of train. Producing this rail only needs existing equipment is improved a little and can produce, and the reduced investment instant effect has obvious Social benefit and economic benefit.

Claims (1)

1, a kind of railway track is used for being connected into successively railroad track, and its structure comprises an I shape rail body and two end faces, it is characterized in that said rail end face is ramp structure, and the inclined-plane at rail two ends is parallel to each other and perpendicular to the bottom surface of rail.
