Referring to FIG. 2, a handle 7 is formed at an upper portion of the bogie body 1, and a cable hanger 4 is installed at the rear of the handle 7.

Referring back to FIG. 1, a rail groove 10 in which the rails 9 are accommodated is formed in the lower portion of the bogie body 1 in front and rear.

3 and 4, the bogie body of the present invention is shown in front and side views, and the bogie body 1 consists of two left and right bodies 11 and 12.

A guideway 13 is attached to the left body 11 and a guideway guide 14 is installed on the right body 12 so that the guideway 13 is guided left and right from the guideway guide 14.

On the other hand, the clutch handle 15 is located in the upper center of the balance body (1). The clutch handle 15 is configured to open the left and right bodies 11 and 12 when pulled up and the left and right bodies 11 and 12 to be lowered.

Referring to FIG. 5, rollers 16 are installed at both sides of the rail groove 10 so that the rollers 16 support both sides of the rail when the truck moves.

Referring to FIG. 6, a driving motor 17 is installed at the center of the bogie body 1, and a gear 19 is extended through the gearbox 18 at the side of the motor 17.

The gear 19 meshes with the wheel 20 shown in FIG. 7 and the wheel 20 drives on the rail to cause the bogie body 1 to move.

Referring to FIG. 7, the wheel 20 has a clutch 21 and the clutch 21 is operated by the operation of the clutch handle 22.

The clutch handle 22 is used to operate the clutch 21 when the motor is under load.

8 shows a control panel of the twin automatic trolley of the present invention, the left panel 31 is provided with a power on / off switch 30, a power lamp 33 and a welding / non-welding switch 34 of the torch 1. do.

The right panel 32 is provided with a welding start button 35, a traveling speed knob 36, a welding stop button 37, a traveling direction toggle switch 38, and a welding / non-welding switch 39 of the torch 2. .

9 shows an electric circuit diagram of the twin automatic trolley of the present invention. When the power switch S1 is turned on, the power supplied to 2, 4 of the housing socket CH3 is rectified by the bridge diodes BD 1,2 and the housing socket ( The power supplied to 2 of CH3) is applied to the capacitor C2 and the resistor R6.

The DC power rectified by the bridge diode BD1 is applied to the ferrite transformer 40. The output of the transformer 40 obtains constant voltages of 24 VDC and 12 VDC. The 24 VDC is used to turn on the power lamp and as a relay operating power, and the 12 VDC is used as the operating power of the IC 41. Another output of the transformer 40 is used for pulse control of the travel motor 17.

When the start switch S2 is turned on, the photo coupler PH3 is operated by a power source connected to the input start switch contact point 4 of the housing socket CH3.

The transistor Q2 is turned on by the operation of the photo coupler PH3 so that the relays RY1 and RY2 operate. The magnetic holding and the torch 1 are turned on by the relay RY1 to start welding, and the traveling motor 17 starts running.

Torch 2 is turned on by the relay RY3 to start welding.

The running speed adjustment is 5, 6, 7 of the housing socket CH3, and the driving speed setting value is input to the IC 41 through the variable resistor VR1, and the FET is obtained through the IC 41 so that the motor speed is controlled. .

When the stop switch S3 is turned on, the power of 3 and 4 of the housing socket CH3 is turned off to stop the driving.

The C potential of the transistor Q2 becomes + 24V, the photo coupler PH3 is turned off, and the relay RY2 is delayed by the charging value of the capacitor C14.

Due to the parallel contact of the relay RY2, the entire process is interrupted by the welding interruption of the torch 1,2 after the creator operation.

Twin automatic bogie of the present invention as described above is used by clamping the torch 1, 2 on the bogie after mounting the rail on the vertical reinforcement.

The distance between the leading and trailing torch is set at 100 to 150 mm intervals and the torch is set to the weld line.

First, the preceding torch and the traveling switch are turned on, and the trailing torch operates the trailing torch at the time of the preceding welding.

During welding, check for blockage of tip, welding condition and running of feeder bogie.

After the welding of the preceding torch is stopped by the limit switch of the welding end point, the welding and the balance driving of the trailing torch are stopped by the setting time and the welding is finished.

The twin automatic trolley of the present invention configured as described above is equipped with one-touch on the rail installed on the vertical reinforcement and performs two-sided automatic welding with two torches, thereby improving the productivity and improving the welding quality.
