Abstract

The utility model relates to a joint of railroad rails. The utility model is particularly designed to solve the problem that the load force of the joints of various railroad rails is relatively weaken. The utility model has the structure that the section of each railroad rail forms an 'H' shape; the end face of each railroad rail forms a stair shape; a turning face of each railroad rail is arranged on a vertical central symmetrical line of the end face of each railroad rail. Because the end face of each railroad rail is made into the turning face from a central vertical line position, the top face of each railroad rail of the projecting part is supported by the middle section vertical face of half of each railroad rail, and thus, the load force after the two end faces are combined can be basically kept constant. The utility model has the advantages that the problem of the reduced load force caused by the prior each improved design can be effectively prevented, the safe running of a train can be ensured on the basis of train vibration reduction, and the utility model has a good guarantee function on the further speed improvement of the train.

Description

Safety exempts to shake rail

The utility model relates to a kind of joint of rail, and specifically a kind of safety exempts to shake rail.

For alleviate because of train wheel to the caused vibrations of the bump at gap place, on Chinese patent, disclose multiple improvement design, promptly the cross section is designed to arc, tenon fourth of the twelve Earthly Branches shape, zigzag or mitered shape or the like for the rail end face of " worker " font rail.Its purpose all is for wheel can be carried out the transition on one rail of back, with the noise that alleviates vibrations and produced from last rail reposefully.Because the rail section is I-shaped, promptly its end face is that facade by the centre supports, and above-mentioned various rail joints have just solved wheel damping problem theoretically, but all reckons without the weight of train to rail.Promptly because rail bears is tens tons to up to a hundred tons gravity, and the rail of above-mentioned all schemes, support to be under the train weight in the nothing that can make rail surface under this pressure and produce deformation, it is raised or sunken that rail surface is tapered off to a point at seam crossing, this safe operation to train is very disadvantageous, thereby can not obtain practical application.

The purpose of this utility model with regard to provide a kind of not only changed original in-line seam, but also the safety with excellent support performance exempt to shake rail, to reduce train vibrations, guarantee driving safety.

The utility model is achieved in that safety exempts to shake the cross section of rail and still be " worker " font, and the end face of rail is a stairstepping, and its turnover face is on the vertical centre line of symmetry of rail end face.Two joint rail are harmonious in the seam crossing convex-concave, and overlap joint has changed the cash joint of original " one " font thus mutually.Because the rail end face is to make turnover face from perpendicular bisector, so the rail surface of ledge still has the support of the rail stage casing facade of half, thereby the bearing capacity of both ends of the surface after being harmonious can remain unchanged substantially.This respectively improves the problem that bearing capacity that designing institute brings reduces with regard to having been avoided original effectively, thereby has guaranteed the security of operation of train on the basis of reducing the train vibrations, to the further speed-raising of train, can play good guaranteeing role.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the vertical view under the two joint track bond states.

As shown in Figure 1, the cross section that safety exempts to shake rail is I-shaped, and the end face of rail is a stairstepping, and its turnover face is on the vertical centre line of symmetry of rail end face.Among Fig. 2, two joint track bonds, convex-concave is harmonious, and forms the transition lap side seam, thereby has realized the wheel smooth transition under the powerful support.

The width a of turnover face is advisable between 1.8-2.5cm on the rail 1.Too small, be unfavorable for forming lap side seam; Excessive, then can correspondingly weaken the rail end face and give prominence to the bearing capacity of half, reduce safety.

Claims

1, a kind of safety exempts to shake rail, and the cross section of rail (1) is " worker " font, and the end face that it is characterized in that rail is a stairstepping, and its turnover face is on the vertical centre line of symmetry of rail end face.

2, safety according to claim 1 exempts to shake rail, and the width a that it is characterized in that described turnover face is between 1.8-2.5cm.
