1 to 3, the line converting apparatus 100 according to an embodiment of the present invention includes a rail connecting bar 110, a screw bar 120, a cam 122, a left wing 111, and a right wing. And a close contact block 113.

The rail connection bar 110 connects a movable left rail (not shown) and a right rail (not shown) to each other. Here, the left rail (not shown) and the right rail (not shown) means a track that can move left and right to change the course of the train. That is, by moving the rail connecting bar 114 to the left and right to switch the track by moving the left rail (not shown) and the right rail (not shown).

The screw bar 120 is positioned in parallel with the rail connecting bar 110 and the motor 121 is connected to rotate by the motor 121.

The cam 122 is connected to the screw bar 120, and the cam 122 moves left and right along the screw bar 120 by the rotation of the screw bar 120.

In addition, the left wing 111 is fixed to the rail connecting bar 110 to be rotatable up and down. Protrusions are formed on the upper and lower surfaces of the left wing 111.

In addition, the right wing 112 is located on the right side of the left wing 112. Like the left wing 111, the right wing 112 is fixed to the rail connecting bar 110 to be rotatable up and down, and protrusions are formed on the upper and lower surfaces.

In other words, the left wing 111 and the right wing 112 are located in a symmetrical shape with each other.

In addition, the cam 122 is positioned so that both ends abut the protrusions formed on the lower surface of the left wing and the right wing. Therefore, when the cam 122 moves left and right along the screw bar 120, the rail connecting bar 110 is moved left and right by the left wing 111 and the right wing 112.

In addition, the upper left of the left wing 111 and the right wing 112 is in close contact with the protrusion formed on the upper surface of the left wing 111 and the right wing 112, the left wing 111 and the right wing 112. Close contact block 113 is located to prevent the rotation to the top.

Since the close contact block 113 has the same length as the cam 122, the left wing 111 may rotate upward when the cam 122 moves to the left end, and the cam 122 may rotate upward. When moved to the right end, the right wing 112 can be rotated upwards.

In more detail, when the cam 122 moves to the left side, the cam 122 pushes and moves the protrusion formed on the lower surface of the left blade 111, and thus, the rail connecting bar 110 connected to the left blade 111. Will move to the left.

When the cam 122 moves to a portion where the close contact block 113 ends, the left wing 111 rotates upwards so that the protrusion formed on the upper side of the left wing 111 has a left side of the close contact block 113. In contact with the surface is fixed to the rail connecting bar 110.

In addition, when the cam 122 moves to the right, the cam 122 pushes and moves the protrusion formed on the lower surface of the right wing 112, so that the rail connecting bar 110 connected to the right wing 112 is right. Go to.

When the cam 122 moves to a portion where the close block 113 ends, the right wing 112 rotates upwards, and a protrusion formed on the upper side of the right wing 112 forms a portion of the close block 113. The rail connecting bar 110 is fixed by being in contact with the right side.

By the above configuration, the rail connecting bar 110 may be firmly and reliably fixed by the contact block 113 when the rail connection bar 110 is moved to the left end or the right end. Therefore, even if the train passes after the track is switched, the left and right rails (not shown) connected to the rail connecting bar 110 may maintain the switched state.

By the above configuration, it is possible to significantly reduce the weight and volume of the track switching device, and also to reduce the manufacturing cost and to simplify the maintenance.

In addition, the left side safety connection bar 130 is connected to the left rail (not shown). In the left safety connection bar 130, a linear groove 131 is formed on the rear surface of the left safety connection bar 130 in a vertical direction. The right safety connection bar 140 is connected to the right rail (not shown) and has a linear groove formed vertically in the longitudinal direction as in the left rail (not shown).

In addition, when the cam 122 moves to the left end, the cam 122 moves downward in contact with the bottom surface of the cam 122, and is inserted into the groove 131 of the left safety connection bar 130. When the left fixing device for fixing the 130 and the cam 122 is moved to the right end, it moves to the bottom in contact with the lower surface of the cam 122, the groove 141 of the right safety connecting bar 140 Is inserted into the right fixing device for fixing the right safety connection bar 140 is located.

In more detail, the left fixing device and the right fixing device are 'b' shaped brackets 150 and 160 and the brackets 150 and 160 which rotate in engagement with the cam 122 when the cam 122 moves to the left and right ends. Fixing bar (153,163) to move up and down by the rotation of the fixing bar (153,163) further includes a spring (152,162) for elastically supporting the upper side.

Therefore, when the cam 122 is moved to the left and right ends, the clamps 150 and 160 rotate with the cam 122, and the fixing bars 153 and 163 move downward by the rotating brackets 150 and 160.

The fixing bars 153 and 163 moved downward are inserted into the grooves 131 and 141 formed in the left and right safety connecting bars, and the left and right safety connecting bars 130 and 140 are fixed by the inserted fixing bars 131 and 141.
