Abstract

A damping steel rail has the advantages that 'click' noises and vibrations caused when wheels pass through a joint of two steel rails are eliminated and convenience in pavement, maintenance, replacement and transportation of a traditional railway is maintained, and also has the characteristics of safety, excellent compatibility and high strength. A steel rail body (3) used in the utility model is completely the same as a traditional steel rail body (3) and is structurally characterized in that a third hole (5) is drilled in an end socket; the diameter of the third hole (5) is the same as that of the original first hole (1) and that of the original second hole(2); the distance between the first hole (1) and the second hole (2) is the same as the distance between the second hole (2) and the third hole (5); the first hole (1), the second hole (2) and the third hole (5) are in the same central line; half of the steel rail is removed along a longitudinal central line (4) of the steel rail body (3) until a perpendicular bisector of the center distance between the original second hole (2) and the new third hole (5); and outlines at two ends of the steel rail body (3) are identical centrosymmetric outlines.

Description

Damping steel rail

Technical field:

The utility model relates to the rail that a kind of railway is used.

Background technology:

At present the rail that generally uses is equipped with two kinds of forms on the railway upper berth: a kind of is that traditional clamping plate, bolt, nut of pass through connect, and another kind is to weld.The former is at train wheel during through two rail joints, can send noise and the vibrations of " click, click ", though the latter does not have noise and the vibrations of " click, click ", but mat formation, keep in repair, change inconvenience, must use cutting machine and welding machine and have suitable high-tech welder just can finish.

Summary of the invention:

The utility model discloses a kind of damping steel rail, purpose be should keep traditional pass through clamping plate, bolt, nut connected mode mat formation, keep in repair, change, transport all advantage easily, in the time of eliminating train wheel through two rail joints again, noise and the vibrations that can send " click, click ".

Rail body of the present utility model and traditional rail body are identical, improvement place is: the one, get out one in the end with first hole of original end and second hole is equidistant, the 3rd hole of equal diameter, same center line, the 2nd, machine away half that locate in two holes, termination, namely remove a part of metal along the longitudinal centre line of rail, be removed to till the perpendicular bisector place of center to center distance in the second original hole and fresh processed the 3rd hole always.The profile of two ends is identical center symmetric profile.

During installation, with traditional rail without any difference, also be to use four original hole clamping plate, also be to use original bolt, nut connected mode, technical requirements and standard are all identical with traditional rail.

The beneficial effects of the utility model are:

1. abate the noise and shake: because the joint of rail changes overlapping into, seam is staggered, in the time of can eliminating wheel through two rail joints effectively, and noise and the vibrations that can send " click, click ".

2. convenient: of the present utility model mat formation, keep in repair, change, transport all fully similarly make things convenient for traditional rail.

3. intensity height: because the utility model steel rail ends has increased a hole than common rail and has been connected with overlapping, the utility model rail joint place intensity is apparently higher than the intensity of the traditional connected mode of common rail.

4. safety is good: if four screws in common rail joint lack one, general considerations is little, still can gather together use reluctantly; If lack two, just problem has been arranged, must see to lack which two: if lack one on one side, also problem is little, the train use of still can meeting an urgent need at a slow speed; If with lacking two on one side, that just bothers big, causes derailment accident probably.But which two the utility model no matter lack, the use of can meeting an urgent need.

If four screws in common rail joint lack three, in any case that just can not use, but the utility model lacks three, if in the middle of first hole or second hole screw is arranged, that also is unlikely to fall apart.

5. compatible good: the employed rail of the utility model, clamping plate, bolt, nut are all identical with the size that traditional rail uses, and favorable compatibility and technology inheritance are arranged.

Description of drawings:

Bottom in conjunction with the accompanying drawings.

Fig. 1 is the three-view diagram of each end of the present utility model, and other parts and common rail are as broad as long, so omit.

Among the figure: 1. first hole, 2. second hole, 3. rail body, 4. longitudinal centre line, 5. the 3rd hole.

The specific embodiment:

The employed rail body 3 of the utility model is identical with traditional rail body 3, improvement place is: the one, get out the 3rd hole 5 of a, equal diameter 2 equidistant with original first hole 1 and second hole, same center line in the end, the 2nd, machine away half of termination, namely remove half along the longitudinal centre line 4 of rail body 3, be removed to till the perpendicular bisector place of center to center distance in the second original hole 2 and fresh processed the 3rd hole 5.The drawn profile of a termination of accompanying drawing, the profile at rail body 3 two ends be identical center symmetric profile (not being axial symmetry, is the center symmetry, just head remove the left side half, afterbody remove the right half).

Implementation detail: the utility model is owing to be overlap joint, if use the processing of original rail, use the physical length of getting up than original weak point a bit, so the rail of new system is longer, grow the length of a machined surface than original relayable rail, could be compatible fully with original rail.

Claims

1. damping steel rail, employed rail body (3) is identical with traditional rail body (3), it is characterized in that, get out in the end one equidistant with original first hole (1) and second hole (2), equal diameter, half is removed along the longitudinal centre line (4) of rail body (3) in the 3rd hole (5) of same center line, is removed to till the perpendicular bisector place of center to center distance in original second hole (2) and fresh processed the 3rd hole (5).

2. damping steel rail according to claim 1,, it is characterized in that: the profile at rail body (3) two ends is identical center symmetric profile.
