BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit breaker for a branch line switching system, and more particularly, A movable rail on which the line converter is moved to line conversion; A fixed cam which is horizontally slid by a rail locking operation that moves in a horizontal direction by the line switching unit; A stationary cam which is coupled to the movable rail at an upper side portion and is horizontally moved along the stationary cam; A securing guide attached to a side surface of the rail securing bracket to guide the securing cam and form a guide bar at the center of the side surface so as to rotate along a round shape at both ends; A rail securing bracket for guiding left and right movement of the stationary cam and coupling the locking guide for horizontal sliding movement of the stationary cam; A second auxiliary stationary arm coupled to the central portion of the first stationary cam to horizontally move the first stationary cam when the first stationary cam is horizontally slidably coupled to the second stationary cam; An insulating paper supporting portion for supporting the rail locking bracket at both sides to serve as an insulator; And a knuckle joint which is adjusted in accordance with the interval of the movable rails to change the length of the rail locking operation.

In general, the line switching system is a device for changing the course so that a railway vehicle running on a basic rail of a railway line can enter a desired direction. Such a line switching system is a manual or mechanical line switcher provided outside the railway So that the traveling course of the railway car is changed by moving the movable rail provided on the inner side of the basic rail back and forth to bring the movable rail into close contact with one of the pair of basic rails.

In the railway system, which is a basic line switching means using the positional transfer switching of the movable rail, a branching device for line conversion has been used as a device for converting the running direction of the railway vehicle on the line. Such a line switching diverter converts the operating line of the railway vehicle by operating the movable rail so that the movable rail can be varied by attraction or power (electric motor, hydraulic pressure, etc.) to the basic rail constituting the base of the running line of the railway vehicle have.

Conventionally, in a branching device for line switching, a movable rail is provided in parallel with the inside of a basic rail, and this movable rail is brought into close contact with and separated from the basic rail in a parallel plane so that the wheel of the railway vehicle closely contacting with the inner rail surface of the basic rail, The traveling course of the railway car is changed by the conversion of the railway. Therefore, as the movable means for changing the railway track of the railway to the basic rail, both ends of the movable rail in the line switching branch are used to move the movable rail on both ends simultaneously so that the movable rail can be closely contacted with and separated from the basic rail. And the line is converted by manual operation by the attraction force such as a lever or automatic operation by the power.

Such a conventional line switching branching device is required to move or separate the movable rail from the basic rail for the purpose of line conversion of the railway car. However, if the operation for transporting and driving the both ends movable rail is broken or malfunction occurs, The movable rail which should be in close contact with the rail for changing the direction of the rail can not maintain the adhesion with respect to the basic rail. If the allowable tightening distance between the movable rail and the basic rail is exceeded, the distance between the standard rail and the rail is deviated, Causing a great deal of risk.

The general railway currently being operated is not equipped with the locking means for the rail switching diverting rail to securely fix the movable rail in the operating position of the movable rail close to the basic rail in order to change the railway, It is true. Particularly, the problem that can cause the allowable distance between the basic rail and the movable rail to exceed the allowable limit is more important from the standpoint of safety protection in the case of the high-speed railway running at high speed.

Therefore, in the high-speed railway, various methods have been proposed as means for tightly locking between the basic rail and the movable rail according to the line change, and they are currently being used in European style. However, The movable rail at both ends is independently clamped by a means such as a hook, so that the complexity and size of the device means are large and the installation cost is also considerable. In addition, there is a possibility that the exposure for the installation site is long due to the long stroke for the chain sawing, and the failure is caused by the repetitive progress and the driving impact.

The most important problem is that most of the locking devices are exposed on the railway, so there is a great concern about corrosion and damage. If breakage of the connections due to such impacts is caused, the chain is lifted, Which is expensive.

In order to solve this problem, it is urgently required to develop a product having excellent tacking ability because it can be bi-directionally chained with a fixed cage and a sub-cage.

The linking cam 212 is a device that horizontally slides by the rail locking operation 320 moving in the horizontal direction by the line switching device 100. The linking cam 212 rotates in the horizontal sliding movement Shaped locking cam 212 and the end of the linear locking guide 122 are fully engaged with each other at the end of the locking guide 122, A semicircular groove is formed on both sides of the straight groove on both sides of the fixed cam 212 so as to be engaged with the semi-circular fixed cancellation 310 and slide.

The stationary cam 310 is fixed to the movable rail 20 by a movable rail bracket 311 at an upper portion thereof so that the stationary cam 212 horizontally moves along the stationary guide 122, One end of which is coupled to the rail clamping motion 320 and the other end of which is coupled to the chainring arm 310.

The locking guide 122 is attached to the rail locking bracket 121 through a fitting hole formed as a long hole and guides the locking cam 212 to form a guide bar at the center of the side surface so as to rotate along the round shape at both ends.

The rail securing bracket 121 is formed with a mounting hole formed as a long hole on its side and allows the stationary cam 310 and the stationary cam 212 to reciprocate therein and allows the stationary cam 310 to move left and right And the locking guide 122 is fixed.

A locking guide 122 for horizontal sliding movement of the locking cam 212 is formed on the side of the rail locking bracket 121 and a pair of rail locking brackets 121 are coupled to both sides of the insulating holding portion 220.

The line switching operation section 352 is coupled to the connection plate 351 to move the rail locking operation section 320 coupled to the connection plate 351 according to the horizontal or vertical movement of the line switching operation section 352, This allows the chain lock arm 310 and the chain lock cam 212 connected to the rail locking operation 320 to perform the horizontal sliding movement while riding the locking guide 122 and to make the horizontal locking movement of the half- 212 and the end of the linear locking guide 122 are fully engaged and mechanically locked.

When the chain stop cam 212 slides horizontally, the chain lock arm 310 is coupled to a semicircular groove at the center of the chain stop cam 212. As the rail chain stop motion 320 moves, The movable rail bracket 311 is horizontally moved to connect the base rail 10 and the movable rail 20 to each other.

At this time, the chain cam 212 is moved horizontally by the rail securing operation 320 by the locking guide 122 and is rotated about the chain lock arm 310 at the end of the locking guide 122, A part of the fixed cam 212 and the end of the locking guide 122 are fully engaged.

The knuckle joint 350 is a part for adjusting the length of the rail fastener driving part 320 by adjusting the distance between the movable rails 20 and is formed in a shape of elliptical or iron and is coupled to the connecting plate 351.

As shown in FIG. 3, in step (a), the locking cam 212 starts to move along the locking guide 122 coupled to the side of the rail locking bracket 121.

In step (b), the break cam 212 is horizontally slid by the rail lock operation 320 moving horizontally by the line switch 100.

In step (c) and step (d), the breakable cam 212 rotates along both end round forms of the locking guide 122 and stops its operation.
