Description

Locking device of rail tap-off {A LOCKING APPARATUS FOR RAIL TURNOUT}

The present invention improves the stability of the running of the train by fixing the toe rail and the nose rail tip of the point portion and the crossing portion of the rail crossing point in close contact with the basic rail and the wing rail during the turnout section of the railway track. It relates to a rail branching device that can be extended to this, in particular, the locking frame portion which is fixed to the base rail to one side of the basic rail is installed on the point portion and the crossing portion of the track branch, and the rail is installed on one side of the basic rail The locking portion installed on the pivoting bar through a spreader bar spoken with a control motor via a shaft on the tongue rail fixing portion and the tongue rail fixing portion is locked and released to the locking frame so that the tip portion of the tongue rail is the basic rail and Selective close contact with the other basic rail, and the nose rail is fixed to one side of both wing rail fixed to the locking frame The rail fixing part is installed, and the rotating bar is delivered to both sides of the nose rail fixing part so that the locking part installed on the rotating bar locks and releases so that the tip of the nose rail is selectively fixed to the wing rail and the other wing rail. The toe and nose moving rails through the locking frame part, the tongue rail and the nose rail fixing part of the railroad turn-off point are automatically contacted with one side and the other basic rail by the sensor signal and locked. Even in the event of a failure of the control motor, it is locked in a locked state, further improving the driving stability of the train passing through the track diverter, preventing noise and vibration generated when the crossing section is running, and significantly maintaining the branch and the crossing section of the turnout. It relates to a locking device of the rail turner to be reduced.

In the conventionally known railway track diverter section, in the point portion and the crossing portion at which the track intersects, a point portion in which a tongue rail is spoken to the branch portion of the basic rail and is in close contact with the basic rail is provided. In addition, the X-shaped fixed cross section rail is installed to be fixed at the intersection of the railway tracks, and the pendulum clip is fastened to the base rail and the point rail of the point section and the bottom of the cross section rail to support and fix it. Is done.

Accordingly, the tungsten rail and the X-shaped crossing rail installed at one side of the rail branch and the wing rail enter into a gap between the base rail and the tongue rail and the wing rail and the nose rail of the point portion when the train runs. Extreme impact is applied to the wheels of the train, and such a shock causes noise and vibration when driving the branch of the train, resulting in poor riding comfort, and malfunction of the monitoring system during train operation. There is a difficulty in maintenance due to abrasion. Especially, when the control motor or the transfer bar is damaged, the tongue or the nose rail moves without locking, so that the train passing through the turnoff is always exposed to the risk of an accident. This was there.

SUMMARY OF THE INVENTION The present invention has been made to improve the above-mentioned conventional problems, and an object thereof is to provide a rail and nose movable rail through a locking frame portion, a tongue rail and a nose rail fixing portion at a point portion and a crossing portion of a railroad track diverter. It is locked to one side and the other basic rail automatically by the signal of the sensor, so that it can be locked, further improving the running stability of the train passing through the track diverter, and preventing noise and vibration generated when driving the point and crossing parts. An object of the present invention is to provide a rail branch device that can significantly reduce the maintenance of the point portion and the crossing portion while preventing the occurrence of malfunction of the monitoring system during train operation.
