Description

Railway Rail Connection Structure {RAILROAD TRACK CONNECTION STRUCTURE}

The present invention, in the railway rail connection structure, in more detail can not only prevent the vibration and noise generated by the joints of the railroad rail connection, but also railroad rail connection that can prevent the joints from opening according to the change of the season. It's about structure.

Generally, as shown in FIG. 1, the rail 2 and the rail 4 are positioned to be in contact with each other when connecting the rail 2 and the rail 4 on which the railroad vehicle travels, and then the connection is fixed to the left and right sides. The piece 6 is attached and fixed with a bolt 8.

However, the rail connection structure as described above has a rapid rattling noise and abrasion when the railroad vehicle is driven at a connection space with a certain interval because the connection degree is different according to seasonal temperature change. The problem is being raised.

Therefore, the wear phenomenon progresses quickly by the wheels of the vehicle being driven by the space between the parts where the rails 2 and 4 are in contact with each other. Therefore, the maintenance period is shortened and the required cost is increased, resulting in economic losses. This situation is increasing.

In addition, in recent years, the coupling between the rails to be connected using a welding, but this may cause a problem that the connection is weakened by the heat generated during the welding, as well as the grinding device during the operation to flatten the welding site after welding There is a problem that even if the flattening operation using a fine planarization is not easy.

In addition, the coupling of the rail by welding has caused a lot of problems, such as the need to cut and replace the rail when the rail is repaired.

Therefore, the present invention was devised in view of the conventional problems as described above, and its purpose is not only to prevent vibration and noise generated by joints of railway rails, but also to open joints according to seasonal changes. To provide a rail rail connection structure that can be prevented.

Bolt: 19

In order to achieve the above object, the railway rail connection structure of the present invention, the coupling holes penetrated to be fixed by bolts and nuts after the fixing plate on both sides of the end of the rail connected to each other on the railway line in the longitudinal direction A plurality of cutouts are formed, and the cut surface is configured to be coupled while crossing each other in contact with each other in the thickness direction of the rail.

The connection structure of the railway rail comprised as mentioned above is demonstrated in detail as follows.

End portions of the rails 10 and 20 forming the rails, which are in contact with each other, are formed with a cutting surface 16 diagonally diagonally formed.

Each of the cut surfaces 16 formed at the end portions on the respective rails 10 and 20 is formed at opposite positions so as to intersect and contact each other.

In addition, coupling holes 12 are formed in the side surfaces of the rails 10 and 20 on which the cut surfaces 16 are formed.

The cut surfaces 16 formed to face each other in an oblique direction at the ends of the rails 10 and 20 can not only be fixed to be in contact with each other, but also have a coupling hole to match the material of the rails 10 and 20. Of course, it can be produced by forming the number of 12).

Bolts 19 and nuts are fastened in the thickness direction to fasten both rails 10 and 20 in the thickness direction so that the coupling holes 12 penetrated on the rails 10 and 20 do not open in the thickness direction. Secure with (17).

In addition, in order to further increase the fixing force of the bolt 19 and the nut 17, both side surfaces of the rails 10 and 20 are formed so as to cover the fixing plate 18 to further reinforce the coupling force.

The connection structure of the railway rail of the present invention configured as described above will be described in detail below with reference to the accompanying drawings.

Figure 2 is a view showing a separated state of the railway rail of the present invention, Figure 3 is a view showing a state in which the railway rail of the present invention is coupled, Figure 4 is a view showing a cross-sectional state of the railway rail of the present invention.

2 and 3, the rails 10 and 20 of the railway line are in contact with each other, and the cut surfaces 16 of the end portions formed as shown in FIG. 2 are diagonally formed in the longitudinal direction. To be in contact with each other.

As described above, when the cut surfaces 16 formed to face both ends of the rails 10 and 20 of the railway line are fixed to be in contact with each other, the cut surfaces of both rails 10 and 20 ( 16, the bolts 19 and the nuts (as shown in FIG. 4) after the fixing plates 18 are positioned to the left and right sides of the coupling holes 12 of the rails 10 and 20 in contact with each other. 17) are joined to each other to be tightened in the thickness direction.

Bolt 19 and nut 17 has a characteristic of high tensile strength that can withstand the degree of expansion and contraction of the rails 10, 20 according to the seasonal temperature.

In addition, the washer 15 or the like is fixed between the bolt 19 and the nut 17 so that the bolt 19 and the nut 17 are not loosened due to vibration of a traveling vehicle or the like.

Therefore, the bolts 19 and the nut 17 are fixed by tightening the cut surfaces 16 of both rails 10 and 20 in contact with each other in the thickness direction so as to be fixed between the rails 10 and 20. There is no empty space in.

Since the incision surface 16 formed at each end surface of the rails 10 and 20 becomes wider at each end portion, the joint portions of the rails which are connected to each other are smoothly formed when they are joined to each other.

Since the cut surfaces 16 of the rails 10 and 20 are coupled to each other, the rails 10 and 20 of the rails which are connected to each other have a form in which the rails 10 and 20 are integrally connected as one rail, so that the coupling force is further increased. Increases.

Both rails 10 and 20 coupled as described above are coupled to the end surfaces of the incision surfaces 16 by diagonally contacting each other so that the wheels of the vehicle traveling on both rails 10 and 20 are The space between the rails 10 and 20 is not coupled to each other by the coupling structure 16 of the coupling surface, so that the driving does not occur smoothly. That is, the wheels of the vehicle are cut off 16 of both rails 10 and 20 because the incision surface 16 is fixed to abut when traveling on both rails 10 and 20 of the vehicle. ) The surface is moved while contacting the upper side at the same time.

In a vehicle traveling on the rails 10 and 20, the wheels of the vehicle are always driven by the cut surfaces 16 of both the rails 10 and 20 when driving the connecting portion. Since the vehicle is driven in contact with the rails of the upper portion of the contacted cutting surface 16 of 20) at the same time, vibration and noise do not occur on the surface where the wheels touch when the vehicle travels.

The pointed portions of the ends of the cut surfaces 16 of the rails 10 and 20 are positioned at the thick portions of the rails to be connected, and the pointed portions of the rails connected to the opposite sides at the thick portions of the cut surfaces 16 as opposed to the pointed portions. Since it is coupled to abut the part, the portion of the cut surface 16 connected as described above is characterized in that the load generated by the vehicle applied to the upper side does not affect the cut surface portion.

In addition, both the rails 10 and 20 fixed by abutting the cut surfaces 16 opposite to each other are bolted to the bolt 19 and the nut 17 in the thickness direction in a state in which they are diagonally abutted to each other in the longitudinal direction. Since the coupling portion of the incision surface 16 is hardly stretched or contracted by seasonal temperature changes, and the entire rails 10 and 20 are stretched and contracted uniformly, the incision surface is brought into contact with each other. (16) part has the characteristic that it does not open.

Therefore, there is an effect that can prevent the vibration and noise generated by the joint of the railway rail by the connection structure of the railway rail of the present invention as described above.

In addition, the coupling structure of the present invention is coupled to the end of the rail to be in contact with the inclined surface obliquely, there is an effect that can be prevented from opening the joint according to the change of the season.

In addition, as a problem occurring in the conventional welding, the welding should be performed at the time of joining, the welded connection part should be ground, and the problem of cutting and replacing the welding part during replacement after use does not occur. There is an advantage.
