Abstract
The utility model discloses a curved surface butt-joint rail, comprising a rail, a fixing connecting plate 1, a fixing screw 2, a butt-joint heat swelling seam 3, and an upper butt-joint interface 6 of a rail 5, which is taken as a curved surface. A train runs on the curved surface butt-joint rail, the heat swelling seam which is not a wider straight seam but a curved seam is left on the upper butt-joint interface; therefore, the train wheel does not pass through a uniform seam which can generate stronger vibration and higher noise, but a small part of the wheel passes through the seam, the other majority part of the wheel presses the rail, therefore, the vibration is weak, the noise is low and the speed of the train can be accelerated. Besides, as the rail in the utility model is changed by only changing the butt-joint interface on the basis of the existing rails, technical schedule of railway construction is not needed to be changed and is easy to be implemented; as the vibration is weak, the damage to the trains and rails is small, thus prolonging the service life of the trains and rails.
Description
Technical field
The utility model relates to a kind of rail.
Background technology
Existing rail is the plane interface butt joint, and the interface seam is the vertical masonry joint of a broad, and train crosses generation than big bang and noise, and influences the speed of train.
Summary of the invention
The purpose of this utility model be to provide a kind of shake little, but noise is low, curved butt joint rail of train high-speed cruising.
Technical solution adopted in the utility model is, this curved butt joint rail comprises rail, fixed connecting plate, fixed screw, the butt joint heat seam that rises, and the last docking port of two rails is curved.
Owing to taked technique scheme, so train travels on the utility model rail,, not the vertical masonry joint of broad though last docking port leaves the heat seam that rises, but curve seam, train wheel is not whole suddenly by a neat sealing, produce bigger vibrations and noise, but sub-fraction is pressed on the sealing, all the other major parts are pressed on the rail, thereby shake for a short time, noise is also little, and the speed of train vibration influence also can be accelerated greatly.In addition, the utility model rail is only to have changed docking port on the basis of existing rail, thereby the tecnical regulations of construction of railways all need not to change enforcement easily.Moreover, shake little, just little to the damage of train and rail, thus prolonged application life of train and rail.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model stereoscopic schematic diagram;
Fig. 2 is the utility model S shape docking port floor map.
The specific embodiment
Embodiment 1, and as depicted in figs. 1 and 2, this curved butt joint rail comprises rail, fixed connecting plate 1, fixed screw 2, and butt joint heat rises and stitches 3, and rail 4 is curved with the last docking port 6 of rail 5.
