Description

Technical Field

[0001] The present invention relates to an auxiliary erection and welding tool for box columns. Background Art

[0002] The steel structure box column is an important steel structure component. The manufacturing steps in the factory usually include first placing the bottom plate forming the box column on the jig, then installing the inner partition or the process partition, then installing the webs on both sides, and finally installing the top plate.

[0003] The existing inner partition erection of box columns is generally carried out manually, and there are many partitions. Erection welding requires ensuring accuracy, and it is difficult to achieve automated erection welding.

[0004] Moreover, in the existing automated erection process, the webs on both sides are assembled first and then the inner partitions are assembled. The assembly is not standardized, resulting in hidden defects in the steel structure, and the internal stress formed thereby is difficult to remove by means of flame baking.

[0005] Most box columns are relatively heavy. During the welding process, they need to be turned over multiple times to achieve multi-layer and multi-pass welding, in order to reduce heat input and balance the deformation generated by welding. The manual turning-over efficiency is low. Summary of the Invention

It can meet the requirements of multiple turnovers during the welding process of the box-shaped column, realizing multi-layer and multi-pass welding, and greatly improving the welding quality.

[0058] When the present invention is actually working, first, the data model of the box-shaped column is imported into the controller. The controller analyzes the model and extracts the theoretical positions of the inner partitions in the model. When the moving gantry 5 travels, the distance sensor 7 measures the position of the distance points in real time and compares them with the theoretical positions to control the starting and stopping positions of the moving gantry 5.

[0059] The steel plates lifted by an external overhead crane are placed between the clamping and positioning units 15. The clamping and positioning units 15 act.

The transfer manipulator of the inner partition stocking assembly 9 acts to move the inner partition and place it on the steel plate. The flattening assembly 6 cooperates to press down the inner partition so that the bottom of the inner partition abuts against the bottom steel plate. Through the action of the first welding robot 4, the inner partition is welded to the bottom plate together.

[0060] The external overhead crane hoists and installs the web plate between the bottom plate and the clamping and positioning unit 15. The clamping and positioning unit 15 operates again to press the web plate against the inner partition plate. After both side web plates are placed, the flattening assembly 6 operates to press and fit the inner partition plate and the web plate, and then the first welding robot 4 welds the inner partition plate and the web plate. When installing the top plate, the external overhead crane moves the top plate between the two clamping and positioning units 15. After the two clamping and positioning units 15 retract, they abut against the side of the box column. After adjusting the top plate to the designed position and the flattening assembly 6 presses the top plate, the first welding robot 4 positions and welds the top plate and the web plate.

[0061] Place the assembled box column on the fixed bench 10. When there is no box column being processed on the first rotating frame 11 and the second rotating frame 12, use the overhead crane to hoist the box column on the fixed bench 10 to the first rotating frame 11 and the second rotating frame 12. Clamp and position the box column through the telescopic clamping devices 20 on the first rotating frame 11 and the second rotating frame 12, and continuously weld the box column by the second welding robot 13 and the third welding robot 14. Flip the box column according to the welding angle until the entire box column is welded.
