The present invention relates to a tungsten toe contact holding device, and in particular, a tungsten toe contact maintaining device for a contact point which is completely locked to the basic rail of the point and locked at the same time as it is locked after being released so that the tongue is not released before the release signal. It is about.

In general, a railroad system using rails as a basic means of transportation has used a diverter as a device for converting the direction of a running railway vehicle on a track.

Such a diverter is converting a track by operating a tungsten rail whose relative displacement can be varied by an external force such as a manpower or an electric motor or a shared pressure cylinder with respect to a basic rail constituting the basis of a railway.

Conventional tapers are provided with a tongue rail with respect to the basic rail, and by connecting and detaching the tongue rail with respect to the basic rail, the wheel of the railway vehicle connecting the inner raceway surface of the rail is moved along the rail to convert the track. .

Therefore, as a moving means for changing the pair of the tungsten rails with respect to the basic rail, the connection between the pairs of the tungsten rails is simultaneously operated to connect and detach the tungsten rails on the side of the line change direction with respect to the basic rails. The connection between the lines is performed by manual operation such as a lever or automatic operation by an electric motor and a shared pressure cylinder.

Such a conventional turnout is an important function in addition to the purpose of converting railways, but the rail must be connected to or separated from the main rail by the main rail. If, for some reason, the connection between the simultaneous driving of a pair of the rail is cut or broken, If the tongue rails connected for the change direction are not firmly connected to the basic rails, the distance between the wheels of the tongue rails and other basic rails extends beyond the distance between the standard wheels of the railway car and derails the vehicle or the traveling speed of the vehicle. There is a big risk of breaking as a moment due to the lock and wheel restraint.

In particular, this problem is a very important design point in the case of high-speed railway.

Conventionally, various methods are used as locking means for firmly fixing at the operating position of the tungsten rail connected to the basic rail for changing the track, but the conventional locking device for the basic rail of the tungsten rail is a means such as a hook. The configuration of locking a pair of tow rails was large, with the size of the device being large and the installation cost also significant.

In addition, since the stroke for the locking operation is long, there are many exposed parts of the installation part, and there was a possibility of failure caused by repeated progress and driving shock.

More importantly, since most of the locking devices are exposed on railroad tracks, there is a high risk of corrosion and breakage, and if a breakage between the connections is caused by such an impact, the locking state is released, which can cause enormous damage to the running railway vehicle.

In addition, there is a problem that there is always a concern that the vehicle derails due to a change in the range of movement of the toe rail when the toe rail moves by a train, and thus the toe rail cannot be closely adhered to the basic rail.

Therefore, the present invention has been devised to solve the problems described above, for ensuring the stability of the point portion according to the improvement of the speed of the branching, for the branching machine to prevent the departure of the wheel by closely contacting the tongue rail to the basic rail It is an object of the present invention to provide a tongue rail contact holding device.

Toner rail close contact holding device for a branch according to the present invention for achieving the above object is a basic rail is installed on the left and right at regular intervals; In the splitter consisting of a pair of tongue rails which are installed to be in close contact with or separated from the side of the respective basic rails, located in the lower portion of the basic rail and the tongue rail, has a predetermined length, has a constant diameter in the center A through hole is formed and a switch rod having a bolt hole formed at both ends of the through hole; A bracket to which a pin is coupled to the basic rail at the same time that the switch rod is inserted and is formed through the inside thereof; A locking rod having one side inserted into the bracket such as a switch rod and the other side engaged with the switch rod; It is characterized by consisting of a connecting rod formed on both sides of the fork shape so that the pin is coupled to the bolt hole of the switch rod.
