Assembly and Welding Line

1. Panel assembly station

Equipped with a set of steel plate splicing devices (including plate thickness difference adjustment device and steel plate surface alignment process facilities) and steel plate conveying positioning adjustment device. On the steel platform, the surface of the steel plate after positioning adjustment is manually aligned and pressed, and then spot welded and spliced. If the steel plates that need to be spot welded are two steel plates with different thicknesses, the plate thickness difference adjustment device can adjust the height to ensure that the upper surfaces of the steel plates are aligned during spot welding, and then manual spot welding is performed.

2. Single-sided welding station

Equip two mobile FCB equipment to perform single-sided and double-sided forming welding on two welds at the same time until all welds are completed. The chain conveyor system transports the welded steel plates to the "marking, inspection, repair and cutting stations".

3. Marking, inspection, repair and cutting stations

The steel plate undergoes necessary inspection and repair at the inspection pit, and the arc starting plate and arc closing plate are cut off.

4. Longitudinal bone vertical conveying station

The roller conveying method is used to transport the pallet filled with longitudinal frames laterally from the span of the factory building C to the span B of the factory. The empty pallet rack can be transported through the above-mentioned

The path is reversely transported back to the longitudinal conveyor belt of span C of the factory building.

5. Longitudinal frame assembly positioning welding station

At the front end of the longitudinal frame installation station, after the steel plate is in place, the pallet containing the longitudinal frame is transported to this station. The driving vehicle takes out the longitudinal frame from the material tray and transports the longitudinal frame to the position that needs to be assembled. Then the assembly mast presses the longitudinal frame onto the steel plate (if necessary, the steel plate is pulled up through the steel plate pulling device to make it align with the longitudinal frame). Better fit), spot welding with a spot welding system on the mast. After spot welding, the mast begins to assemble the next longitudinal frame. The chain conveyor system transports the sections with longitudinal frames to the "longitudinal fillet welding station".

6. Longitudinal fillet welding station

It is equipped with a longitudinal fillet welding machine with 24 electrodes (welding heads), which can weld 6 longitudinal bones at the same time. The segments that have completed longitudinal fillet welding are transported to the floor and girder installation station by a segment transport trolley, or to the transverse shift station and then transferred out to other lines.

7. Floor and longitudinal girder assembly station

Each line is equipped with two spot-welded portal frames with longitudinal ribs and girders. After the sections are in place, the floors and girders that need to be installed are transported to the installation spot welding position by driving vehicles. Each mast is equipped with 6 CO2 welding equipment to spot weld the floor plates and longitudinal steel plates together to complete the basic installation. Spot welding work. The sections that have completed spot welding of floor plates and longitudinal girders are transported to the next floor plate and longitudinal girder welding station by a section transport trolley.

8. Floor and longitudinal girder welding station

Each line is equipped with three floor and longitudinal girder welding gantry, which is mainly used for welding floor plates and girders. Each gantry is equipped with 12 CO2 welding machines. The wire feeders and welding guns of all 12 welding equipment are hung on the electric chain hoist hanging structure under the main beam. After the welding is completed, the segmented transport trolley will transport the segments to the next work station.

9. Move out of the workstation in sections

After completing the above work, the sections are transported to the shipping station by the section handling trolley. At the transport station, the sections are lifted up to a height of 2.5m above the ground by the section lifting device. The hydraulic flatbed truck then drives under the segment. The lifting device places the sections on the supports of the flatbed truck. The segments are transported out of the segment production workshop by hydraulic flatbed trucks.

10. Segmented transport trolley

After the segments are welded at the longitudinal frame welding station, the segments are transported to all subsequent stations using the segment transport trolley.
