Description

Turnout system of railroad rail}

The present invention relates to the improvement of a point part, a lead part, and a crossing part in the branching part used for the part which one railroad track (a pair of rail) divides into two railroad tracks.

More specifically, the stability of the base plate in the lead portion between the point portion and the crossing portion can be improved while improving the stability and extending the life of the vulnerable tongue portion at the point where the front rail of the fork is started. In the cross section, the efficiency and economics of using the cross can be improved, and the guard rail fastening part can be adjusted at the guard rail fastening part, thereby improving the precision and convenience at the time of new laying, and the convenience and economy at the time of maintenance. We want to improve it.

As is well known, the branching section is the most important and weak part of the railway line.

In the point portion 10 'of the conventional branching machine, as shown in FIG. 5, the portion where the tongue rail 2' contacts the base rail 1 'is constructed while leaving the base rail 1' as it is. Only 2 ') is processed to be gradually tapered and pointed, so that the tip of the tongue (2') was bound to be very fragile.

Therefore, a frequent repair for the toe rail (2 ') is required, and accordingly there is a problem that requires a large cost for maintenance.

In the conventional lead portion 20 ', as shown in FIG. 8, since the rail bottom support portion of the general base plate 21' is limited to the shoulder portion 22 'which fastens the coil spring, a lot of force is applied to the shoulder portion 22'. This action may be vulnerable in strength, there is a problem that requires very careful in precise laying because the base plate 21 'can be twisted left and right when laying.

In the conventional crossing portions 40 'and 40 ", as shown in Figs. 13 and 14, although the price is low, the general assembly crossing 41a having a low ride comfort, short life, and short maintenance cycle, and excellent performance However, there are various problems caused by using only the integrated manganese crossing 41b having a high price and inconsistency in replacing the entire crossing due to some defects, and also in the conventional crossing guard portion 30 '. Likewise, by using the integrated guard block 32 'in a configuration in which the guard rail 31' is fixed at the main rail 1b 'at a predetermined interval (Frenzy Way), the flange way cannot be adjusted. The maintenance was difficult and the life of the guardrail 31 'was short.

The present invention has been devised in view of the above-described problems, and improves the configuration of the portion where the basic rail and the tongue contact at the point portion, thereby reinforcing the tongue, thereby greatly extending the life of the tongue rail, The base plate complementing the rail bottom support ensures precise laying and stability.The crossing part can be selectively used for general assembly crossing, integral manganese crossing, and nose block type crossing in consideration of economics and practicality. In order to control the Hurenji Way in the configuration that combines the negative guard rail is to ensure the accuracy of the configuration, and to improve the life and stability.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, Figure 1 is a view that can see the whole branch of the railway rail for the understanding of the present invention, the point portion 10 and the lead portion 20, the crossing guard portion 30 and the crossing portion 40 It can be seen that the tap-off is configured.

Looking at, the base rail (1) and the tongue rail (2) in contact with each other to be in contact with each other, but cutting the one side of the base rail (1) in contact with the tongue rail (2) to form a cutting portion 11 In the tungsten rail 2, the shape of the contact portion 12 is processed so as to correspond to the cut portion 11.

As shown in FIGS. 3A and 3B, the contact portion 12 of the tongue rail 2 was gradually closer to the unprocessed shape while maintaining the processed angle.

6 is a plan view of the lead portion 20, FIG. 7 is a cross-sectional view taken along line BB of FIG. 6, FIG. 7A is a plan view of FIG. 7, in the lead portion 20, the main rail seated on the base plate 21. The base plate 21 in which the rail support jaw 22 which supports 1a and the whole bottom part of the lead rail 2a was formed was used.

9 illustrates a cross section 40 and a crossing guard portion 30 of the branching machine, and FIG. 10 is a cross-sectional view taken along line C-C of the crossing guard portion 30.

Looking at it, it was fixed using an adjustable guard block 32 between the main rail (1b) and the guard rail (31).

12 is a sectional view taken along the line DD of the cross section, and when the cross section 40 is constructed, a general assembled cross or an expensive integrated manganese cross may be used. By using the cross section, it is economical and advantageous in terms of performance and the like.

In the figure, reference numeral 3 is a sleeper, 4 is a base plate, 5 is a coil spring clip, 6 is a clamp, 7 is a rail brake, and 8 is a throttle.

Looking at the operation of the present invention as described above, to form a cutting portion 11 in the basic rail (1) that the tongue rail (2) in contact with the point portion 10 to minimize the machining of the tongue rail (2) to be in contact In this case, the service life can be greatly extended by reducing damage and wear of the tongue rail 2 as much as possible within the range of maintaining the strength of the basic rail 1.

Since the lead portion 20 uses the base plate 21 on which the rail support jaw 22 is formed, the rail is installed more firmly and stably, and the base plate 21 does not move, which is advantageous for precise laying.

In addition, in the crossing guard portion 30, the adjustable guard block 32 is used as a means for fixing the guard rail 31 to the main rail 1b, so that precise laying can be performed at the time of new laying. When it is necessary to adjust the control block 32 will be able to adjust simply using the throttle 8 without having to replace.

In addition, when constructing the crossing of the crossing unit 40, general assembly crossing, manganese crossing, and nose block crossing can be selectively used according to the use purpose and economic conditions, and in particular, the crossing is constituted using the nose block crossing 41. In this case, it is more economical than the manganese crossover.

According to the present invention as described above, in the branch of the railway line, wear can be reduced by improving the strength of the tongue rail at the point portion, the stability of the base play fastening can be secured at the lead portion, and the use of crossing is selected at the crossing portion. It is designed to improve the stability and reliability of the tap-off by extending the width and using the adjustable guard block in the crossing guard part, which is convenient for precise assembly and maintenance, and extends the life of the guard rail. .
