In addition, the rotational force of the gas line drum motor 220 and the cable drum motor 320 is preferably connected to each drum (210,310) by a power transmission means such as gears, chains, belts.

In addition, the manual handle (H) may be further installed on their axes in case the gas line drum 210 and the cable drum 310 are not automatically driven by a motor.

Further, guide brackets 230 and 330 are formed on both sides of the open front sides of the gas line housing 200 and the cable housing 300, and the gas lines GL and the cables CA are formed on the guide brackets 230 and 330, respectively. The guide rolls 240 and 340 are rotated so that they can be smoothly moved while being in contact with the clouds.

In this case, it is more preferable that the guide rolls 240 and 340 are respectively provided with a pair of upper and lower sides, and the gas line GL and the cable CA pass through the upper and lower pairs, respectively.

In addition, the open upper and rear surfaces of the gas line housing 200 and the cable housing 300 are sealed by the cover 400.

In this case, the cover 400 has a sunshade that extends to a portion where the guide brackets 230 and 330 are installed, so that the rain is not affected by rain even when the gas line GL and the cable CA are released or wound. It can also be installed to work.

In addition, one side of the cover 400 is provided with operation buttons (B1, B2) for driving the device gas line drum motor 220 and the cable drum motor 320 of the present invention, respectively.

Meanwhile, a power box 350 is installed on one side of the cable housing 300, and the power box 350 includes a 440V and 220V conversion transformer including a reverse phase relay, which is a reverse phase protector 352 as shown in FIG. 6. 354, forward rotation operation MC 356, reverse rotation operation MC 358, and cable power supply NFB 360.

Here, the reverse phase preventer 352 is a kind of sensor for detecting a reverse phase, and is a means for sensing whether the power is reversed or normal and controlling the forward / reverse rotation MCs 356 and 358 accordingly.

In addition, the transformer 354 is a means used to step down 440V to 220V because the anti-phase prevention device 352 operates at 220V.

In addition, the forward rotation operation MC 356 is an MC for operating the motor described above in the forward rotation when the phase of the switchboard normally enters, the reverse rotation operation MC 358 operates the motor in the forward rotation when the phase of the switchboard is reversed. MC to make.

In addition, as shown in Figure 7, the switchboard 500 is provided for each workplace, the switchboard 500 is provided with a power outlet 510 for driving the lug welding robot.

In addition, although not shown in the drawings, each workshop is provided with a gas line for supplying gas and air to the apparatus of the present invention, like the switchboard 500.
