The present invention relates to a method of converting a product into a product having an improved quality when a repair is required due to abrasion or damage to a branch part at which a railroad splits into two railroad tracks, in particular, at a railroad track. It is related to the structure of the tap-off by the changer, and it is easy to replace and improve the safety and robustness and improve the assembly and maintenance as compared with the conventional one by the improvement of the operation method of the point part and the configuration of the tongue contacting the basic rail. will be.

As is well known through the configuration of the conventional tapping through Figs. 1 to 4, the straight basic rail 201 and the curved basic rail 201 'is composed of a connection of a length of 20,000mm from the beginning of the tapping and straight tungsten rail 202 and curved thongs 202 'are articulated and connected to straight rail 203 and curved rails 203', and straight thongs 202 and curved thongs 202 'are straight The portion that is in close contact with the basic rail 201 and the curved basic rail 201 ′ is sharply cut into a general type (see FIG. 3) and is configured to be in close contact.

In the point portion 210 of the conventional turner, the articulated point portion is configured to be in contact with or separated from the straight and curved tungsten rails 202 and 202 'on the straight and curved basic rails 201 and 201'. As shown in FIG. 2, the articulated point portion is a straight line and a curved tangle, so that the straight and curved tangle rails 202 and 202 ′ and the straight and curved rails 203 and 203 ′ connected thereto are loosely connected. (202) (202 ') is the way to move the noise and vibration in accordance with this method is a lot of problems, resulting in a deterioration of the ride comfort, and by the vibration and shock to the part where the tongue rail and the lead rail is connected Many wear and damage has occurred.

In addition, when constructing the part where the straight and curved trail rails 202 and 202 'contact the straight and curved basic rails 201 and 201', the straight and curved tungsten rails 202 and 202 'are left as they are. ) Only to be tapered and pointed to make contact, but accordingly the tip of the tongue was very weak.

Therefore, the frequent maintenance for the toe rail is required, and accordingly, there is a problem that requires a large cost for maintenance.

Due to this problem, there is a problem in that the replacement operation due to wear and breakage of the point part is frequently performed in the conventional turner. However, in the past, there was a wasteful problem of replacing the whole branching system because there was not a method system capable of intensively replacing only the point portion in the whole branching system with a product having improved performance. Since the above problems are repeated over and over again, maintenance problems have to be repeated.

The present invention provides a method of intensively and efficiently converting the point portion of the existing branching machine in order to improve the problems of the conventional branching section as described above to improve the problem in the configuration of the existing branching while efficiently performing the replacement work. By doing so, it aims to solve the maintenance problem of the existing tap-off at once.

The present invention, in the existing installed tapping machine, by cutting the straight base rail, curved base rail and straight rail of a certain length from the end of the point portion to remove with the tongue and the curved rail is removed as a whole, The new rail of the joint is joined to the seam plate, but in this process, the tongue rail is elastically modified, and the parts contacting the tongue rail and the base rail are machined to be brought into contact with each other. Looking at the recirculation method of the present invention in detail based on the drawings as follows.

In the drawing, the number of the small size described on one side of the sleeper of the rail is a number for distinguishing the sleeper, which is different from the symbol with a leader line for explaining the main part of the invention.

Basically, the diverter 100 has a point portion 10 which allows the straight rail 2 and the curved rail 2 'to contact or be spaced apart from the straight rail 1 and the curved rail 1'. The straight rail 3 and the curved rail 3 'connected to the straight rail 2 and the curved rail 2' are gradually moved from the straight rail 1 and the curved rail 1 '. It is divided into a lead portion 20 which is separated and connected to the next crossing and guard portion 30, and a crossing and guard portion 20 which is completely separated by crossing two railroad lines.

And all the rail lengths described below are in 'mm' units.

Rail Cutting Process

Straight basic rail (1) The curved basic rail (1 ') and the straight rail (3) are cut between the sleeper 18 and the sleeper 19, respectively.

The length of the cut of the straight basic rail 1 and the curved basic rail 1 'is about 10,700 from the beginning of the tapper 100 (just before the first sleeper), and the straight rail 3 is cut. The length is 11,717, calculated backwards from the beginning of the crossing between sleepers 37 and 38.

The reason for cutting between sleepers # 18 and # 19 sleepers is to secure an appropriate rail length for forming an elastic tungsten and to secure a minimum space necessary for fastening parts for connecting rails and rails. Cutting shorter lengths (between sleepers less than 18 sleepers) will result in excessive elasticity of the tongue and lack of space for fastening the rails and components for connecting the rails. When cutting and re-exchanging between sleepers exceeding 19 times, it is necessary to use a longer expensive rail than other rails, and the number of installation of complex and expensive fixed float plate and branch base plate is increased. A problem arises in that the price (conversion cost) increases.

Therefore, the present invention can be said to derive the appropriate cutting position in consideration of the proper action and cost of the tap-off.

Curved rail 3 'is generally abrasion and need not be cut because it has to be replaced entirely.

Rail dismantling process

The linear basic rail 1 and the curved basic rail 1 'of the cut point portion 10, and the linear rail 3 and two pieces from the portion connected to the linear tungsten 2 to the cut position The tongue rails 2 and 2 'are separated from each top plate on the sleeper 9, that is, the point top plate 5, the fixed top plate 5' and the base plate 5 "and removed.

The names of the top plate such as the point top plate 5, the stationary top plate 5 ', and the base plate 5 "are referred to as point top plate, heel top plate, and lead base plate in the conventional branching machine. In the description of the name used as the name of the top plate is improved for convenience.

Since the curved rail 3 'is a part of the structural characteristics of the turnout 100, because the railway wheel is strongly rubbed and wears a lot, the entire track (about 15,380) is removed over the lead portion 20.
