Abstract
The utility model relates to a rail for trains, which is adopted by railway departments. The utility model aims to overcome the defects of the prior art so as to provide a rail with oblique joints, and the rail with oblique joints has simple structure, reasonable design and small shaking force of trains in operation. The utility model is mainly characterized in that the joint surfaces of both ends of a rail are oblique planes, the oblique angle alpha is from 25 to 45 DGE, and the best angle of the oblique angle alpha of the utility model is 35 DGE. The utility model has the characteristics of simple structure, reasonable design, small shaking force of trains in operation, etc.
Description
The utility model relates to the rail that a kind of railway interests uses.
Now, the rail interface is for facing directly, for preventing that rail from expanding with heat and contract with cold, all leave gap (as shown in Figure 1) during installation between the rail of each rail joint, train running is when this gap, and wheel can be subjected to very big impact force, and bumps and shake, reduced the application life of each parts of train, be unfavorable for that also train improves the speed of service.In addition, because the noise that vibrations are produced also has sizable harm to passenger's health.
The purpose of this utility model is intended to overcome the deficiency of prior art, and provides a kind of simple in structure, reasonable in design, the Rail with oblique joint that the train running shaking force is little.
Main feature of the present utility model is that the interface at rail two ends is the inclined-plane, and oblique angle a is the 25-45 degree.
The best angle of the utility model oblique angle a is 35 degree.
The utlity model has simple in structure, reasonable in design, characteristics such as the train running shaking force is little.Use the utility model can make train wheel joint smooth transition between rail, produce collision and impact force hardly, thereby each component life of train is increased, security performance improves, and maintenance cost reduces.Also greatly reduce simultaneously noise.Lay a good foundation for further improving train speed.
Fig. 1 is existing rail draw bail schematic diagram.
Fig. 2 is the utility model structural representation.
Fig. 3 is the utility model rail draw bail schematic diagram.
Below in conjunction with accompanying drawing the technical solution of the utility model is further described:
As shown in Figure 2, the interface at the utility model rail two ends is the inclined-plane, and oblique angle a is the 25-45 degree.The best angle of the utility model oblique angle a is 35 degree.Structure when the utility model rail connects as shown in Figure 3.
Claims (2)
1, a kind of Rail with oblique joint, the interface that it is characterized in that the rail two ends is the inclined-plane, oblique angle a is the 25-45 degree.
2, Rail with oblique joint according to claim 1 is characterized in that oblique angle a is 35 degree.
