Abstract
The utility model relates to a damping railroad track. The damping railroad track comprises two abutted rails, two clamping plates and a rectangular block, wherein, the two clamping plates are clamped on both sides of the rail webs at the abutted parts of the abutted rails; two opposite rectangular grooves are respectively arranged on the rail webs at the abutted pars of the abutted rails, the rectangular block is arranged in the rectangular hole formed by the two rectangular grooves; the height direction plane of the rectangular block is in interference fit with the inner wall of the rectangular hole, a dilatation joint is left between the horizontal plane of the rectangular block and the inner wall of the rectangular hole; the rectangular block is clamped between the two clamping plates. The damping railroad track of the utility model can be mounted conveniently, the impact vibration produced to the rail connected part when a train runs by is effectively reduced, the comfort of the passengers is improved, the fatigue resistivity of the rail metal is increased and the service life of the rail is prolonged.
Description
Technical field
The utility model relates to railroad track, the railroad track of vibration in the time of particularly can reducing train and advance.
Background technology
Railroad track comprises the rail of butt joint, owing to exist the problem that metal expands with heat and contract with cold, all leave the slit about 10-15mm between the two butt joint rail, no matter which direction running of train like this, the capital makes between the work plane of two rails and produces difference in height, the capital rushes to the impact shock of a track afterwards after producing and depressing last track earlier again, and the passenger who takes in the train can clearly experience the noise of this vibration and its generation.Such impact shock not only can reduce the fatigue resistance of rail metal, increases the breakage of rail joint, also can cause the train passenger discomfort.
The utility model content
Technical problem to be solved in the utility model is: a kind of vibration damping railroad track that reduces impact shock is provided.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
The vibration damping railroad track, it comprises the rail and two clamping plate of two butt joints, two clamping plate are clipped in the web of the rail both sides of two butt joint track bonds place; It also comprises rectangular block, have relative rectangular channel on the web of the rail of two butt joint track bonds place, described rectangular block is provided with in the rectangular opening of two described rectangular channels compositions, the short transverse of rectangular block and rectangular opening inwall interference fit leave the shrinkage joint between the horizontal direction of rectangular block and the rectangular opening inwall; Rectangular block is clipped between two clamping plate.
The utility model is squeezed into a rectangular block on the web of the rail of butt joint rail, rectangular opening inwall interference fit on the short transverse of rectangular block and the web of the rail, leave the shrinkage joint between the rectangular opening inwall on the horizontal direction of rectangular block and the web of the rail, like this when train passes through joint, can eliminate or reduce the difference in height between the two rails work plane, thereby reduced the impact shock of wheel to rail
The utility model vibration damping railroad track is easy for installation, effectively reduces the impact shock that rail joint produces when train is advanced, and improves the comfortableness that the passenger takes, and has increased the fatigue resistance of rail metal, has prolonged rail application life.
