Abstract
Provided is a steel rail ensuring non-vibration and low-noise running of a train, which is characterized in that front and tail ends of two linking steel rails are disposed in a complementary L shape along a vertical and symmetrical center line of the steel rail. L-shaped end faces of connecting ends of the steel rail are connected in a manner of stagger overlap joint. The stagger overlap joint face of the steel rail is vertical to the ground, and the length of the overlap joint is over one time as that of the maximum contraction amount of an expansion joint. Accordingly, at the time of maximum contraction amount, no horizontal and transverse and through gap will be disposed at the joint of bearing and connecting end faces of the steel rail, and stable and low-noise running of a train can be guaranteed.
Description
Affiliated technical field
The utility model relates to a kind of railway track, especially a kind of rail that ensures the shockproof low noise operation of train.
Background technology
At present, known railway track and method of attachment, all adopting the track bond end face is the docking method of attachment on plane, for the connection rail that the prevents long distance distortion of expanding with heat and contract with cold, usually in the junction of every section rail, all leaves certain shrinkage joint.Owing to adopting docking calculation to connect rail, it stays the shrinkage joint (mating interface) at the place, cross section that connects the rail joint end place larger, when rolling the shrinkage joint, wheel had a small uphill, downhill to move at the sealing place, form the crash shock of wheel and rail and the noise that vibration produces, had a strong impact on steady, the low noise operation of vehicle.When particularly temperature is low especially, the amount of contraction of rail is larger, cause the flexible interface of rail to increase, the crash shock of train wheel and rail will strengthen this moment, had a strong impact on the safe operation of train, accelerate simultaneously the damage of rail, wheel, car body annex and the article of transporting, reduced the application life of rail facility and vehicle.In addition, the vibration when the train passenger-carrying and noise have also affected passenger's travelling quality.
Summary of the invention
In order to overcome the deficiency of existing railway track and connected mode, the invention provides a kind of rail that ensures the operation of train friction low noise.
The utility model relates to and solves the technical scheme that its technical problem takes and be:
A kind of rail that ensures the operation of train friction low noise, comprise rail two ends and rail, it is characterized in that: the two ends of two link rail are complementary L-type along rail vertical symmetry center line, method of attachment is to adopt the method for staggered overlap joint to connect the L shaped end face of the link of rail, and the staggered faying surface of rail is perpendicular to the ground, and lap length is more than a times of this interface shrinkage joint maximum collapse amount length.Make track bearer connection end face junction when amount of contraction is maximum, horizontal cross do not occur and connect sealing, guaranteed the steady and low noise of train operation.
The invention has the beneficial effects as follows: can ensure train safe operation under held stationary, low noise state, the vibration and the noise that have reduced the collision of train wheel and rail stroke sealing and produced, also prolonged simultaneously train and orbital facilities application life, reduced because the frequent damage of high vibration to conveying goods also makes the passenger take train more comfortable.
Description of drawings
The present invention will be further described below in conjunction with drawings and Examples

The specific embodiment
In Fig. 1 is embodiment illustrated in fig. 2, in the two ends of two link rail, front end rail tail end 4 otch of front end rail overlap joint section 1 are L-shaped along rail vertical symmetry center line 6, and rear end rail overlap joint section 2 rear end rail head ends 5 otch rail vertical symmetry center lines 6 are inverted L-shaped, it is complementary L shaped that the two ends of two link rail are, method of attachment is to adopt the method for staggered overlap joint to be connected the L shaped end face of front end rail tail end 4 and rear end rail head end 5 links, and the staggered faying surface of rail is perpendicular to the ground, and lap length is more than a times of these interface shrinkage joint 3 maximum collapse amount length.Make track bearer connection end face junction when amount of contraction is maximum, horizontal cross do not occur and connect sealing, guaranteed the steady and low noise of train operation.
