Abstract
A vibration-reducing railway track comprises a plurality of mutually butting steel rails. The shapes of the butting ends of neighboring steel rails are modified to form mutually engaging V or W-shaped male-female joints. A clearance 10-15mm wide is left between the V or W-shaped male joints and the V or W-shaped female joints. Effectively reducing the impact vibration produced by flat-seamed steel rail joints during the locomotion of the train, the vibration-reducing railway track of the utility model, when improving the ride comfort of passengers, improves the fatigue resistance of steel rail metal and lengthens the serviceable life of the steel rails. In addition, the traction resistance is reduced, and not only saves energy resources but also is conducive to train acceleration.
Description
Technical field
The utility model relates to a kind of railroad track, particularly a kind of vibration damping railroad track of impact shock can reduce train and advance the time.
Background technology
China and countries in the world railway track joint are flush joint, owing to there is the metal problem of expanding with heat and contract with cold, the rail joint place all leaves the slit about 15mm, no matter train is to which direction running like this, the capital rushes to the impact shock of a rail afterwards after producing and depressing last rail earlier again, the passenger who takes in train simultaneously can clearly experience the noise of this vibration and its generation, such impact shock is all repeating every day, increase along with train travel density, the generation frequency of this impact shock is very high, not only have influence on passenger's comfortableness, the more important thing is, frequent impact shock can reduce the fatigue resistance of rail metal greatly, increases the breakage of rail joint; Increased the tractive resistance of locomotive simultaneously, wasted the more energy, be unfavorable for the speed-raising of train, frequent impact shock also can impact the overall structure of train, reduces the safety factor of train.
The utility model content
The purpose of this utility model is to address the above problem, and a kind of vibration damping railroad track is provided.This kind vibration damping railroad track, comprise the some rail of butt joint mutually, the termination shape that changes described adjacent rail butt end leaves the slit of 10-15mm to form " V " shape or " W " shape male and female connector that coincide mutually between described " V " shape or " W " shape male contact and described " V " shape or " W " shape famale connector.
The utility model vibration damping railroad track, the bottom sharp corner of described " V " shape or " W " shape famale connector is made arc surface.
The utility model vibration damping railroad track, described " V " shape or the lateral wall of " W " shape male contact and the connecting portion of end face are made arc surface, and described " V " shape or the inside wall of " W " shape famale connector and the connecting portion of end face are made arc surface.
The utility model vibration damping railroad track also can be by to existing rail transformation of the way back of using, it is convenient to implement, reduced the impact shock that the rail joint of flush joint produces after improving simultaneously effectively when train is advanced, rail length no matter, at the train direct of travel, greatly reduce the impact shock of generation, when improving passenger's riding comfort, increase the fatigue resistance of rail metal, prolonged rail application life; Reduced tractive resistance, energy conservation helps train speed raising; And line maintenance is convenient, has reduced the circuit day-to-day maintenance.

The specific embodiment
For further specifying the utility model vibration damping railroad track, now come concrete the elaboration with the following Examples:
Fig. 2 is the adjacent rail butt end vertical view of the utility model vibration damping railroad track embodiment 1, the termination shape of its adjacent rail butt end is " V " shape male and female connector that coincide mutually, as shown in the figure, " V " shape male contact 1 and 2 slits 8 of leaving 10-15mm of " V " shape famale connector.
Fig. 3 is the adjacent rail butt end vertical view of the utility model vibration damping railroad track embodiment 2, the termination shape of its adjacent rail butt end is " W " shape male and female connector that coincide mutually, as shown in the figure, " W " shape male contact 1 and 2 slits 8 of leaving 10-15mm of " W " shape famale connector, the bottom sharp corner 7 of " W " shape famale connector 2 is made arc surface simultaneously.
Fig. 4 is the adjacent rail butt end vertical view of the utility model vibration damping railroad track embodiment 3, the termination shape of its adjacent rail butt end is " V " shape male and female connector that coincide mutually, as shown in the figure, " V " shape male contact 1 and 2 slits 8 of leaving 10-15mm of " V " shape famale connector, the bottom sharp corner 7 of " V " shape famale connector 2 is made arc surface simultaneously, the lateral wall 3 of " V " shape male contact 1 is made arc surface with the connecting portion of end face 5, and the inside wall 4 of " V " shape famale connector 2 is made arc surface with the connecting portion of end face 6.
The embodiment of the utility model vibration damping railroad track is not only to be limited to above severally, and the mode of the termination shape of the adjacent rail of every change butt end all can be implemented.
The utility model vibration damping railroad track can be by to existing rail transformation of the way back of using, it is convenient to implement, reduced the impact shock that the rail joint of flush joint produces after improving simultaneously effectively when train is advanced, when improving passenger's riding comfort, increase the fatigue resistance of rail metal, prolonged rail application life; And reduced tractive resistance, energy conservation helps train speed raising.
