Abstract

The utility model discloses a tooth type rail connector which can eliminate the impact of rail connectors and train wheels. One end of a rail [1] is machined into a tip [3], and a support beam part is machined into a square key assembly [6]. One end of a rail [2] is machined into a groove [4], and a support beam part is machined into a rectangular key groove group [7]. After the rails are connected by the original rail connection method, the rail surface is still a flat surface when the train wheels run through the rail surface, and thus the utility model eliminates the impact of the train wheels and the rail connectors.

Description

Tooth-like rail joint

The utility model relates to a kind of rail joint, and rail one end is pointed, and another root rail one end is the groove shape, the rail joint of forming in the most advanced and sophisticated insertion groove.

Present railway rises for the shrinkage heat that adapts to rail itself, leaves the space at the joint of rail, when train travels on railway, wheel and the collision of rail joint place, send very strong noise, and make body oscillating, cause take uncomfortable, shortened application life of train again.

Task of the present utility model provides a kind of tooth-like rail joint, and it can eliminate the bump of wheel and rail joint, reduces noise, raising ride comfort degree, the train purpose in application life that prolongs thereby reach.

For solving above-mentioned task, solution of the present utility model is: do not change the linking method of original rail joint, change the shape of rail joint, rail one end is pointed, at brace summer the square key group is arranged partly; Another root rail one end is the groove shape, at brace summer rectangle keyway group is arranged partly.During butt joint, in the most advanced and sophisticated insertion groove, the square key group is inserted rectangle keyway group, makes the rail rail level be a plane, and at tip and bottom land; The space is left in square key top and keyway bottom, rises with the shrinkage heat that adapts to rail self.Thereby reach and promptly weaken noise, improve the ride comfort degree, prolong train application life, adapt to the purpose that rail self shrinkage heat rises again.

Certainly, rail butt joint shape also can be jagged, but combination principle is identical.

Owing to adopted tooth-like butt joint in the above solution, can eliminate the bump of wheel and rail very easily, reduce the vibration of vehicle body, simple in structure, need not increase how many costs.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the lateral view of first embodiment of the utility model.

Fig. 2 is the lateral view of second embodiment of the utility model.

Fig. 3 is the lateral view of the 3rd embodiment of the utility model.

Fig. 4 is the lateral view of the 4th embodiment of the utility model.

Fig. 5 is the lateral view after two rails of the described embodiment one of Fig. 1 separate.

In the lateral view of joint shown in Figure 1.The groove 4 of rail 2 is inserted at the tip 3 of rail 1, and leaves the space between tip 3 and groove 4, rises with the shrinkage heat that adapts to rail self.The square key group 6 of rail 1 is inserted the rectangle keyway group 7 of rail 2, and when wheel forwarded the rail joint place to, the pressure effect made rail deformation, caused butt joint place to misplace up and down.The purpose that square key group 6 is inserted rectangle keyway group 7 is exactly in order to stop rail to misplace up and down.Insert grooves 4 and square key group 6 is inserted under the acting in conjunction of rectangle keyway groups 7 most advanced and sophisticated 3, when making rail joint be in wheel to cross, rail level still is a plane.

The combination principle of Fig. 2, Fig. 3, Fig. 4 is identical with Fig. 1.Its difference is:

tip

8,9,10 and

groove

11,12,13 are respectively had any different.

Fig. 5 is the lateral view after joint shown in Figure 1 is taken apart.The tip 3 of rail 1 is horn shape, and the 6th, the square key group of support beam end, the groove 3 of rail 2 is horn shape, and the 7th, the rectangle keyway group of support beam end.The butt joint principle is identical with the butt joint principle of Fig. 1.

Certainly, the shape at rail tip and the shape of groove are not limited to above-mentioned four kinds of forms, also other similar type can be arranged.

Claims

1. the rail joint formed of the groove of the tip by rail one end, another root rail one end, it is characterized in that: the groove [4] of rail [2] is inserted at the tip [3] of rail [1].

2. rail joint according to claim 1 is characterized in that: the brace summer of rail [1] partly has square key group [6].

3. rail joint according to claim 1 is characterized in that: the brace summer of rail [2] partly has rectangle keyway group [7].

4. according to claim 2 or 3 described rail joints, it is characterized in that: square key group [6] is inserted rectangle keyway group [7].
