Description

Technical Field

[0001] The present invention relates to a method for assisting the erection and welding of box columns. Background Art

[0002] The internal diaphragm of a steel structure box column is an important component of the box column, which has an important impact on the mechanical properties of the steel structure column. The quality of the internal diaphragm often affects the mechanical properties of the column itself and thus affects the safety of the entire building.

[0003] The existing erection of the internal diaphragm of the box column is generally carried out manually, and there are many diaphragms. It is necessary to ensure the accuracy during erection and welding, and it is difficult to carry out automatic erection and welding.

[0004] Moreover, in the existing automatic erection process, the two side webs are assembled first and then the internal diaphragm is 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 flame baking.

[0005] Most box columns are relatively heavy and need to be turned over multiple times during the welding process 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, which greatly reduces the processing efficiency of the box column. Summary of the Invention

[0006] The purpose of the present invention is to provide a technical solution for the method of assisting the erection and welding of box columns in view of the deficiencies of the existing technology. The steps of this erection and welding method are simple. It can not only realize the automatic erection and welding of box columns, but also meet the requirement of turning over multiple times during the welding process to achieve multi-layer and multi-pass welding, improving the quality and accuracy of the erection and welding of box columns.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] The method for assisting the erection and welding of box columns is characterized by including the following steps:

[0009] S1. Import the data model of the box column into the controller, parse the model by the controller and mark the theoretical position of the internal diaphragm, compare the position of the distance sensor measured in real time when the moving gantry of the erection tooling walks with the theoretical position at the distance point (0, 0), and control the start and stop of the moving gantry;

[0010] S2. Lift and install the bottom plate of the box column by a crane and place it between the clamping and positioning units. The clamping and positioning units act. After adjusting the bottom plate to be parallel to the ground rail, reset one side of the clamping and positioning units, and keep the other side of the clamping and positioning units stationary;

[0011] S3. The mobile gantry moves along the ground rail to a specified position, the inner partition stocking component operates, the inner partition is moved and placed on the bottom plate, and the flattening component cooperates to press down the inner partition so that the bottom of the inner partition abuts tightly against the bottom plate. The first welding robot operates to weld the inner partition and the bottom plate.

[0012] S4. The overhead crane hoists the web plate between the bottom plate and the clamping and positioning unit. The clamping and positioning unit operates again to press the web plate tightly against the inner partition. When installing the other side web plate, the corresponding clamping and positioning unit retracts, and the flattening component retracts. After placing the web plate, the clamping and positioning unit presses tightly against the corresponding web plate. At the same time, the flattening component operates to press the inner partition and the web plate together, and then the first welding robot welds the inner partition and the web plate.

[0013] S5. After the required inner partitions and web plates are installed, the overhead crane hoists the top plate between the clamping and positioning units. After the clamping and positioning unit retracts, it abuts tightly against the side of the box column, and the top plate is adjusted to the designed position. The flattening component presses the top plate tightly, and the first welding robot positions and welds the top plate and the web plate to complete the erection of the box column.

[0014] S6. The erected box column is hoisted to the fixed gantry by the truss crane. After the box column on the welding fixture is welded, it is hoisted to the welding fixture by the truss crane again. The telescopic clamping device of the welding fixture clamps the box column to be welded, and the second welding robot and the third welding robot weld the box column. During the welding process, the rotating mechanism of the welding fixture drives the telescopic clamping device to rotate to achieve the overall welding of the box column.

[0015] This erection and welding method has simple steps. It can not only achieve the automatic erection and welding of the box column, but also meet the requirement of multiple turnovers during the welding process to realize multi-layer and multi-pass welding, improving the quality and accuracy of the erection and welding of the box column.

By driving the second frame body and the first telescopic rod to move back and forth along the slide rail by the second motor, the box column can be tightened by the tightening head, improving the stability and reliability during the erection of the box column. The first frame body improves the stability and reliability of the installation of the entire clamping and positioning unit.

[0018] Further, the flattening component in step S2 includes an L-shaped plate, a lifting plate, a flattening strip, and a cylinder. The cylinder is arranged on the L-shaped plate.

The ends of the two first guide rods are connected by a balance rod. A second guide rod is movably connected to the lifting plate. The second guide rod is connected to the flattening strip through a boosting plate. A shock-absorbing spring is sleeved on the second guide rod. The shock-absorbing spring is located between the lifting plate and the boosting plate. By cooperating with the flattening component to press down the inner partition board, the bottom of the inner partition board can be tightly pressed against the bottom steel plate. The L-shaped plate improves the stability and reliability of the cylinder installation. The cylinder can drive the lifting plate to move up and down through the piston rod via the connecting block. Furthermore, the boosting plate can be driven to drive the flattening strip to move, so as to press tightly against the inner partition board, improving the assembly efficiency of the box column. The sleeves and the balance rod improve the stability and reliability of the first guide rod during movement. The first guide rod improves the stability and reliability of the lifting plate during movement. The second guide rod and the shock-absorbing spring perform shock absorption and buffering on the boosting plate and the flattening strip.

[0019] Further, the inner partition board stocking component in step S3 includes a first housing and a transfer manipulator. The first housing is provided with a guide groove.
