The present invention relates to a track switching device used to change the course of a railway vehicle.

In general, the track switching device is a device that changes the course so that a railroad car traveling on a railroad can enter a desired direction. Such a track switching device uses a manual or mechanical train (rail switching device) provided on the outside of the track to move the tungsten rail installed inside the basic rail to the left or right to move the tungsten rail to any one of the basic rails of the pair of basic rails. By closely adhering, the course of the railway vehicle can be changed.

Conventional track switching device is provided on the outer side of the basic rail 20, as shown in Figure 1, the electric rail (10) for switching the track by moving the tongue rail (21); It is interposed between the memory (38a) (38b), the memory (38a) (38b), which are coupled to the tongue rail 21 to face each other, the cutting edge (36) capable of close or chain adjustment of the tongue rail (21) ), The tongue rail connecting portion 30 having a connecting member 37 for connecting the tip 36 and the memory 38b, and a screw jaw 31 for connecting the tip 36 and the memory 38a. ; A connection section 13 connecting the tongue rail connecting portion 30 and the electric train 10; It is provided on the upstream side of the tongue rail connecting portion 30 to connect a pair of tongue rails 21, it is composed of a means 40 for moving the tongue rail 21 is connected to the train 10 by the operation. .

Accordingly, the tongue rail 21 is in close contact with the basic rail 20 so that the course of the railroad track can be changed to change the course of the railway vehicle.

However, according to the conventional track switching device, since one end of the connection is connected to the center of the tip, the worker is working on the railroad in order to perform the close adjustment or the lock adjustment of the tongue rail. It may occur. In addition, when performing the adjustment control operation between the tips, the operation is performed while checking the lock operation part of the train, and the distance between the tip operation and the lock operation part of the train machine is very inconvenient to carry out the adjustment control operation alone, and thus many The maintenance cost will increase according to the number of workers.

In addition, since the tip is protruded upward than the sleeper, when the worker walks on the track or works on the track, there is a possibility that a safety accident may occur due to the foot being caught in the tongue connecting part, especially during the night work. There was a problem that the maintenance cost increases because parts installed in the lower part or the lower part of the railroad car collide with the tiptooth when passing through the tipping point which has been projected upward, and the part of the track switching device and the railroad car is damaged.

Accordingly, the present invention was made to solve the above problems,

It is an object of the present invention to enable the operator to perform a close adjustment or lock adjustment operation on the outside of the railroad to prevent safety accidents due to the railway vehicle that can occur during the operation on the railroad as well as the operator's chain It is to provide a line switching device capable of adjusting the adjustment at a distance close to the direct operating part.

Another object of the present invention is to ensure that the tip tip is provided at a lower position than the sleeper to prevent a safety accident from occurring when the worker walks on the track or works on the track, especially when the tip is caught between the tips during the night work. Even if the railroad car passes through the tip of the railroad, the parts installed on the lower part or the lower part of the railroad car do not collide with the tip of the rail, so there is no risk of breaking the track switching device and a part of the railroad car. It is to provide a switching device.
