Abstract
The utility model relates to a joint structure of steel rails of railways. The end head of the joint of the steel rails is provided with left and right /front and back staggered inserting end heads for convex-concave blocks, wherein the matched faces of the inserting end heads for convex-concave blocks are remained with thermal expansion preventing gaps; the longitudinal length of each of the inserting end heads for convex-concave blocks is larger than that of each of the thermal expansion preventing gaps. A purpose-made fish tail-shaped clamping plate with slotted holes is used for performing the functions of the clamping plate as well as a vertical support of two inner side end faces of the inserting end heads for convex-concave blocks. When wheels run on the seaming positions of the steel rails, a steel rail discontinuity state existing originally is changed into a steel rail continuity state so that the utility model reduces the vibration and the noise of trains, and makes trains run stably and passengers feel comfortable.
Description
The utility model relates to railway, and concrete is a kind of seam construction of railway track.
With connecing the economic construction development, communications and transportation day is becoming tight, and the overwhelming majority of communications and transportation is being born in railway transportation, and China constantly has new trunk railway to put into effect every year.Railway becomes with steel rail laying, and the coefficient of thermal expansion of steel is big, expands with heat and contract with cold and causes rail to be bent in order to prevent rail that the Various Seasonal temperature difference causes, and when steel rail laying, the slit of suitable thermal expansion will be left in its joint.Its two ends of traditional rail are tack, produce vibration at gap at joint place train wheel owing to the interruption of rail.The general length of present single rail is 20 meters, and 50 place's seams are arranged in one kilometer long railway approximately, travels with 60 kilometers speed per hour as train, calculates with 20 joint compartments, and the per minute train will stride across about 4000 rounds of seam, and promptly each second is through 66.6 rounds.Heavy compartment, frequent vibration can cause the waste of energy, and the energy that is wasted so all becomes destructive power and noise, causes serious harm to rail facility and environment.
The purpose of this utility model is to overcome above-mentioned shortcoming, a kind of seam construction of railway track is provided, wheel is travelled at the gap place by existing rail to be interrupted originally to be improved to rail continuous, reduce the vibration and the noise of vehicle, make vehicle operating steady, it is comfortable that the passenger feels.
The purpose of this utility model is achieved in that
A kind of seam construction of railway track leaves the slit that supplies the rail heat expansion in the seam crossing termination, and the fishtail clamping plate in belt length hole are equipped with bolt in the I shape web both sides of seam crossing rail, it is characterized in that:
A. about being shaped on the termination, rail joint place/the convexo-concave block grafting termination that is staggered front to back, this convexo-concave block grafting termination fitting face leaves the slit that heat supply is expanded;
The longitudinal length of convexo-concave block that b. should the grafting termination is greater than the length in heat supply expansion slit;
C. use the fishtail clamping plate in special belt length hole, the gradient of the bottom surface of the upper and lower end face gradient of these fishtail clamping plate and the last rail of rail and the last end face of lower shoe is corresponding, after fishbolt was tightened, these fishtail clamping plate became the vertical support of rail convexo-concave block grafting termination two inner side ends; The fishtail clamping plate that the more original butt end rail of the length of these fishtail clamping plate uses have an amount of elongation, and this amount of elongation is greater than the longitudinal length of convexo-concave block grafting termination.
The purpose of this utility model can also realize by following measure:
The staggered convexo-concave block grafting termination of termination, described rail joint place be about the ladder rectangular configuration of half and half symmetry.
The staggered convexo-concave block grafting termination of termination, described rail joint place is that an end has the rectangle projection to hold the structure that corresponding single rectangular recess is arranged in addition.
Described rail joint termination is that an end has the double square projection, and the other end has the structure of corresponding double square groove.
Described rail joint termination is the projection of biasing, the structure that groove combines with ladder rectangle convexo-concave block.
The convexo-concave block plug of termination, described rail joint place can rectangular square toes shape, also can pointed shape triangular in shape, also can be rounded shape.
The utility model has following actively useful effect:
1. increase the ride comfort sense of passenger in the compartment;
2. the minimizing environmental noise has positive role to environmental protection;
3. reduce the vibration of railway and vehicle, the loss of locomotive and rail is reduced, increase the service life;
4. reduce the energy that locomotive consumes because of vibration at the gap place, energy efficient;
5. roadbed and destruction of bridge power are reduced;
6. the more smooth of road surface played the support effect to improving the speed of a motor vehicle;
