[0001] GIRDER TYPE SWITCHING APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a girder type branching machine, and more particularly, to a girder type branching machine applied to a magnetic levitation train or a monorail.

The girder type branching machine is applied to a magnetic levitation train or a monorail, and has a running surface of a train integrally provided in the girder, and a catenary line for supplying electric power to the train is provided on a side surface of the girder.

For example, the girder-type splitter is configured so that the moving girder can be pivoted in the train height direction axis (S in Fig. 9) to selectively connect one fixed girder to the other two fixed girders. According to the turning operation of the moving girder, one side fixing girder, the moving girder and the other side fixing girder are sequentially connected to enable the running of the train selectively.

FIG. 3, the side surfaces of the moving catenary line 31 and the side surfaces of the first and second fixed catenary lines 32 and 33 extend continuously in the train traveling direction (x-axis direction) with a height set in the z-axis direction . The set height enables stable contact with the current collecting shoe 42 when the train 41 travels.

The side surfaces of the moving electric wire 31 and the side surfaces of the fixed electric wire (which will be referred to as a first fixed electric wire for convenience) 32 always make contact with the current collecting shoe 42 continuously. Therefore, the current collecting shoes 42 can stably supply electric power to the train 41 while sliding the plane formed on the side surfaces of the moving and fixed electric wire lines 31, 32.

Also, the moving catenary line 31 and the first fixedtotal line 32 are in surface contact with each other at least in the z-axis direction. In other words, since the movable catenary line 31 is lowered from the upper side of the first fixed catenary line 32, it can be more closely contacted by the load acting in the gravity direction.

The moving electric cable 31 includes a fixed portion 311 fixed to the side surface of the moving girder 10, a rotation portion 312 coupled to the fixed portion 311 by a rotation axis 313 arranged in the train width direction (y- And a motor 314 installed on the side of the moving girder 10 and connected to the rotating shaft 333 to rotate the rotating part 312 about the y axis.

The moving girder 10 is installed so as to pivot around the axis 11 in the train height direction (z direction) in the xy plane. Therefore, as the movable electric wire 31 rotates around the axis 11 of the moving girder 10 in the train height direction (z direction), the fixed portion 311 and the rotating portion 312 rotate integrally. The rotation unit 312 can further rotate in the vertical direction about the y-axis in the fixing unit 311 by the rotation shaft 313. [

The rotation part 312 of the moving catenary 31 which is rotated about the rotation axis 313 in the fixing part 311 is connected to the first fixedtotal line 32. The moving catenary line 31 has the downward inclined plane 301 inclined toward the lower side of the z-axis and the x-axis direction on the rotating portion 312. [ The first fixed electric wire (32) has an upward inclined plane (302) at an end portion (321) which is inclined to face the downward inclined surface.

The side surface of the end portion 321 of the first fixed electric wire 32 and the rotation portion 312 of the mobile electric wire 31 forms a continuous continuous plane. The sides of the fixed portion 311 and the rotation portion 312 of the moving catenary line 31 and the side surfaces of the end portion 321 and the side surface of the first fixed electric wire 32 are continuously formed.

Since the side surface of the moving electric cable 31 and the side surfaces of the first and second fixed electric wire lines 32 and 33 are continuously connected to each other as described above, when the train 41 travels, the moving electric cable 31 and the first and second fixed electric cable 32, and 33 can be ensured by continuous wetting of the current collecting shoe 42.

Therefore, the noise due to impact and vibration is reduced at the connecting portion of the moving catenary line 31 and the first and second fixed toothed lines 32 and 33 and the current collecting shoe 42 is prevented from being damaged, 1 and the first and second support members 51, 52, 53 supporting the second fixed electric wire lines 32, 33 can be prevented from being damaged.
