Abstract

The utility model relates to a steel rail with seamless connection, which belongs to the technical field of skew intersection or lap joint groups at tail ends of the steel rails. The utility model particularly relates to the steel rail with the seamless connection. The utility model provides the steel rail with the seamless connection, which can realize smooth transition of wheels and is simple in structure. The steel rail with the seamless connection comprises the steel rail, and the key points of the structure are as follows: orthogonal projection lines of the parallel end lines of the two steel rails on the bottom surfaces of the steel rails form 45-degree angles with the horizontal line at the butt joint of the steel rails and the two steel rails are connected through connecting devices at the side parts.

Description

The seamless link rail

Technical field

The utility model is divided the fixed building portion, the big class of the building of road, railway or bridge, railroad track of belonging to by International Patent Classification (IPC) (IPC); The railroad track annex; Lay the mechanical group of different kinds of railways, big group of the joint of rail, rail end oblique or overlap little technical group field; Relate in particular to a kind of seamless link rail.

Background technology

Rail is the main building block of railroad track.Its function is that the wheel of pilot engine vehicle advances, and bears the immense pressure of wheel, and is delivered on the sleeper.Rail is necessary for wheel rolling surface continuous, smooth-going and that resistance is minimum is provided.At electric railway or automatic block district, rail also can doublely be done the usefulness of track circuit.

Existing rail in use, when wheel when track bond place, can produce and jolt, vibrate, the transport of railway is caused adverse effect.

Summary of the invention

The utility model is exactly at the problems referred to above, and a kind of seamlessly transitting and seamless link rail simple in structure of wheel of realizing is provided.

For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises rail, and its structural feature is in track bond place, the parallel end line of two rails is at the orthography line and the horizon angle at 45 of rail foot surface, and described two rails links to each other by the linkage of sidepiece.

As a kind of preferred version, linkage described in the utility model comprises clamping plate, bolt, the nut with first through hole, rail is provided with and corresponding second through hole of described first through hole, be provided with in second through hole can be in second through hole movable sleeve pipe, casing length is greater than the length of second through hole, and described bolt links to each other clamping plate by first through hole, sleeve pipe, second through hole, nut with rail.

The utility model beneficial effect

1, can realize seamlessly transitting of wheel

The utility model track bond place, the parallel end line of two rails are at the orthography line and the horizon angle at 45 of rail foot surface, and described two rails links to each other by the linkage of sidepiece; Owing to done 45, make that the termination of joint two rails is interlaced, when wheel crosses, do not have the unsettled moment all the time.So the utility model can be realized seamlessly transitting of wheel.

2, thermal adaptability is strong

The utility model linkage comprises clamping plate, bolt, the nut with first through hole, rail is provided with and corresponding second through hole of described first through hole, be provided with in second through hole can be in second through hole movable sleeve pipe, casing length is greater than the length of second through hole, and described bolt links to each other clamping plate by first through hole, sleeve pipe, second through hole, nut with rail; By above-mentioned linkage, rail can be stretched, well compensated expanding with heat and contract with cold of rail.

3, simple in structure

The utility model just will carry out tilt variation at the track bond end line, the linkage of employing form by the parts that are easy on the market purchase and compound mode simple, so the utility model is simple in structure.

Description of drawings

Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with the drawings and the specific embodiments, the utility model is further elaborated.Should be appreciated that the specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Fig. 1 is the utility model vertical view;

Fig. 2 is the utility model side portion structure schematic diagram;

Among the figure, 1 is that clamping plate, 2 are that bolt, 3 is rail.

The specific embodiment

As shown in the figure, the utility model comprises rail 3, and at rail 3 joints, the parallel end line of two rails 3 is at the orthography line and the horizon angle at 45 of rail 3 bottom surfaces, and described two rails 3 links to each other by the linkage of sidepiece.

Described linkage comprises clamping plate 1, bolt 2, the nut with first through hole, rail 3 is provided with and corresponding second through hole of described first through hole, be provided with in second through hole can be in second through hole movable sleeve pipe, casing length is greater than the length of second through hole, and described bolt 2 links to each other clamping plate 1 by first through hole, sleeve pipe, second through hole, nut with rail 3.

Above content is to further describing that the utility model is done in conjunction with concrete preferred implementation; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the definite protection domain of claims that the utility model is submitted to.
