When the base plate 360 is slightly adhered to the bottom of the line, the support bolt 352 is brought into close contact with the bottom of the line to prevent the base plate 360 from shaking. can do.

The support members 362 are provided on both sides of the reference plate 360 so that the reference plates 360 are closely attached to the bottoms of the lines and are detachably supported on the rails of the lines.

The supporting member 362 is formed at both ends of the supporting body 310 and the support body 310 which are rotatably fixed to both sides of the reference plate 360 and extend and retracted in the longitudinal direction, And a clamping piece 320 in the form of a clamp which is fitted and fixed.

The supporting plate 310 is rotated by the reference plate 360 and the supporting plate 320 is fitted and fixed to the side of the rail with the reference plate 360 positioned on the bottom of the rail, It can be fixed in a state of being in close contact with the bottom of the line.

It is preferable that the angle adjusting nut 341 is fixed to the horizontal bar 315 whose both ends are fixed to the main support pipes 311 of the support body 310.

Therefore, when the angle adjusting bolt 343 is screwed to the angle adjusting nut 341 while passing through the base ring 342 while the angle adjusting bolt 343 is passed through the base ring 342, the support body 310 rotates the rotation pin 312 The support body 310 moves away from the reference plate 360 while being rotated in the opposite direction about the rotation pin 312. As a result,

At this time, when the angle adjusting bolts 343 are tightened while the support pieces 320 are fitted to the side ends of the rails, the support body 310 can be firmly held between the reference plate 360 and the rails.

The fixing member 370 fixes the case member 500 to the reference plate 360. The fixing member 370 includes a fixing nut 371 fixed to the reference plate 360 and a fixing bolt 371 fixed to the fixing nut 371 through the case connecting member 510 formed on the case member 500, Gt; 372 < / RTI >

The fixing member 370 further includes a height adjusting block 390 having a hole through which the fixing bolt 372 passes to adjust the height of the case member 500 in the reference plate 360.

The fixing bolt 372 is passed through the case member 500 and the height adjusting block 390 while the height adjusting block 390 is seated on the reference plate 360 and the case member 500 is seated, (371).

Therefore, the case member 500 can be fixed at a height as high as the height of the height adjusting block 390 from the reference plate 360 by the height adjusting block 390. [

The height adjusting block 390 is installed between the reference plate 360 and the case member 500 so that the case member 500 is installed between the reference plate 360 and the case member 500. [ Of the rail can be made close to the top height of the rail, so that information can be easily provided to the train moving at high speed.

The fixing member 370 further includes a cushioning member 330 having a hole through which the fixing bolt 372 penetrates so as to alleviate vibrations transmitted from the reference plate 360 to the case member 500. The buffer member 330 is preferably composed of a rubber pad.

The fixing bolt 372 is passed through the hole of the case member 500 and the hole of the buffer member 330 while the buffer member 330 is positioned between the case member 500 and the reference plate 360 And can be screwed to the fixing nut 371.

That is, when the cushioning member 330 is installed between the reference plate 360 and the case member 500, the vibration generated when the train moves is buffered by the case member 500 through the reference plate 360, It is possible to prevent the member 500 from being burned.

As described above, in the present invention, the case member 500 is fixed to the reference plate 360 while the reference plate 360 is positioned at the bottom of the line. The support bolts 352 screwed to the respective support nuts 351 provided on both sides of the reference plate 360 are tightened or loosened to adjust the height of the reference plate 360 to the left and right sides, To be brought into close contact with the floor.

After the support bodies 310 are rotated on both sides of the reference plate 360 by rotating the support body 310 about the rotation pin 312 fixed to the reference plate 360, And the support piece 320 is fitted to the side end of the rail in a state in which the elastic body is contracted by inserting the sub support pipe 313 into the sub support pipe 313.

At this time, since the contracted elastic body is extended and the sub support pipe 313 protrudes from the main support pipe 311, the reference plate 360 is stably fixed between the rails by the support bodies 310 supported by the rails .

When the angle adjusting bolt 343 is screwed into the angle adjusting nut 341 while passing the angle adjusting bolt 343 through the base ring 342, the supporting body 310 rotates about the rotation pin 312 The support pieces 320 can be firmly supported on the rails since they are about to approach the reference plate 360 while being rotated.

That is, since the support body 310 is firmly supported between the reference plate 360 and the rail, the reference plate 360 can be stably fixed to the line.

Further, in order to install the case member 500 on the line, it is not necessary to carry a separate working tool for drilling the line or for drilling the line.

9, the power supply unit 160 includes a power supply generating unit 166. The power supply generating unit 166 includes a power supply generating unit 166, Failure of power supply may occur. In addition, in the conventional load-sharing type parallel system, when the first system fails, the remaining two systems take charge of the whole load. Therefore, as the load ratio increases instantaneously from 50% to 100%, a large current similar to the startup current is required. The phenomenon of falling below the set value may occur.

In order to solve this problem, the present invention is characterized in that a pair of first power source generation section 166A, a second power source generation section 166B, a pair of first power source generation section 166A and a second power source generation section 166B And a bypass line for a bypass circuit 166d and 166d 'provided in the bypass lines of the pair of first and second power supply generating units 166A and 166B, (166e, 166e ', 166f, 166f'), and a parallel-connected unconnected short-circuiting switching unit 166c (166e, , 166c '.

(166c, 166c ') for parallel connection added to the bypass line output side of the present invention, and the outputs of the first system power generation unit 166A and the second system power generation unit 166B The secondary side of the transformer is connected in series.

In addition, the bypass unconnected short-circuiting switching switches 166f and 166f 'for synchronizing with the solar cells 162c and 162c' for supplying external power are constituted by static switches and filters 166g and 166g ' Can be further connected.

Therefore, when an asymmetrical deviation occurs between the rectification sections 166a and 166a 'and the output voltages of the inverter sections 166b and 166b' of the first and second system power generation sections 166B, only a simple voltage drop occurs, Cause the cause of the fault and shut off the cause of the load system ripple and the power failure of the fault current.

In addition, if a fault occurs during parallel load operation in parallel and the remaining two systems are dedicated to the load, the load current instantaneously rises and an inrush current larger than the inverter rated capacity may be generated. In the present invention, FAIL is generated in the first power supply generation unit, and at the same time, the uninterruptible short-circuiting redundant switch for parallel connection The output power of the 2-phase power generation unit having the normal operating voltage applied thereto is passed through the parallel unconnected unidirectional switching unit for parallel connection to energize the output transformer of the 1-phase power generation unit in the FAIL state so that the normal output voltage is continuously supplied Since the load current hardly changes in impedance on the power source side, It can significantly reduce the inrush current caused by a dedicated load.

Accordingly, the external power source of the present invention may be any one of a piezoelectric element, a solar power, an AC commercial power source, and a DC power source. The power source generating unit considers scalability so that various external power sources can be conveniently used. Piezoelectric elements can be installed between the rail and the road to produce electricity when the train passes. The sunlight can be installed on the track or on the top of the trailer to produce electricity. Also, since the AC commercial power source and the DC power source are supplied in the signal line provided in the conventional line side or the station, they can be input through the power input ports 162b, 162b ', 162c and 162c' and used stably.
