Description

Technical Field

[0001] This utility model relates to the field of steel structure straightening technology, and more specifically to a straightening device for steel structure columns and beams. Background Technology

[0002] In the field of steel structure fabrication and installation, the straightness of columns and beams is a core indicator for ensuring the structural load-bearing capacity and stability. Because steel structure columns and beams are susceptible to stress during rolling, welding, and handling, deformations such as localized bending and excessive overall deflection often occur. Straightening devices must be used for correction to meet engineering quality requirements.

[0003] Current steel structure column and beam straightening devices generally suffer from inconvenient rotation and adjustment when dealing with workpieces requiring straightening in multiple directions and at multiple locations. For columns and beams with multiple bends, traditional devices often struggle to achieve flexible rotation. If operators want to straighten the bends on different sides of the column and beam, they need to disassemble, flip, and re-fix the column and beam multiple times. This process is not only time-consuming and labor-intensive, but also significantly extends the straightening operation cycle. Utility Model Content

[0004] The purpose of this invention is to provide a straightening device for steel structure columns and beams that can straighten curved parts on different sides without repeated disassembly and flipping, thereby improving straightening efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A straightening device for steel structure columns and beams includes a workbench with a mounting frame. The mounting frame has a movable seat and a transverse moving mechanism for driving the movable seat to move horizontally. A straightening hydraulic cylinder is mounted on the movable seat and is driven by a straightening pressure plate. Lifting mechanisms are provided at both ends of the workbench, and lifting plates are driven by the lifting mechanisms. Column and beam placement assemblies are provided at both ends of the lifting plates, and a column and beam rotation mechanism is provided at one end of each column and beam placement assembly.

[0007] Furthermore, the lateral movement mechanism includes a horizontal lead screw that is rotatably mounted on the mounting frame, a displacement drive motor that drives the horizontal lead screw to rotate is mounted on the mounting frame, and the moving seat is threadedly connected to the horizontal lead screw.

[0008] Furthermore, the lifting mechanism includes two vertical frames disposed at both ends of the worktable. One vertical frame is provided with a lifting screw and a lifting motor for driving the lifting screw to rotate. One end of the lifting plate is threadedly connected to the lifting screw. A guide rod is vertically fixedly connected to the other vertical frame. The guide rod is arranged parallel to the lifting screw. The other end of the lifting plate is slidably sleeved on the guide rod.

[0009] Furthermore, the column beam placement assembly includes a first mounting plate and a second mounting plate respectively fixedly connected to both ends of the lifting plate. The second mounting plate has a through hole, and a turntable is rotatably arranged at the through hole. The turntable has a square through groove.

[0010] Furthermore, the column-beam rotation mechanism includes a placement block rotatably mounted on the first mounting plate. The placement block has a square placement groove on the side facing the second mounting plate. The square placement groove is correspondingly arranged with the square through groove. A rotary motor for driving the placement block to rotate is mounted on the first mounting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This application provides lifting plates driven by a lifting mechanism at both ends of the workbench. The lifting plates are equipped with column beam placement components and column beam rotation mechanisms.

[0016] like Figure 1 and Figure 2 As shown, a straightening device for steel structure columns and beams includes a workbench 1, a mounting frame 2 on the workbench 1, a movable seat 3 on the mounting frame 2 and a transverse moving mechanism for driving the movable seat 3 to move horizontally, a straightening hydraulic cylinder 4 mounted on the movable seat 3, a straightening pressure plate 5 driven by the straightening hydraulic cylinder 4, lifting mechanisms at both ends of the workbench 1, lifting plates 6 driven by the lifting mechanisms, column and beam placement assemblies at both ends of the lifting plates 6, and a column and beam rotation mechanism at one end of the column and beam placement assembly.

[0017] The lateral movement mechanism includes a horizontal lead screw 7 that is rotatably mounted on the mounting frame 2. A displacement drive motor 8 that drives the horizontal lead screw 7 to rotate is mounted on the mounting frame 2. The moving seat 3 is threadedly connected to the horizontal lead screw 7.

[0018] The lifting mechanism includes two vertical frames 9 disposed at both ends of the workbench 1. One vertical frame 9 is provided with a lifting screw 10 and a lifting motor 11 for driving the lifting screw 10 to rotate. One end of the lifting plate 6 is threadedly connected to the lifting screw 10. A guide rod 12 is vertically fixedly connected to the other vertical frame 9. The guide rod 12 is arranged parallel to the lifting screw 10. The other end of the lifting plate 6 is slidably sleeved on the guide rod 12.

[0019] The column and beam placement assembly includes a first mounting plate 13 and a second mounting plate 14 that are fixedly connected to both ends of the lifting plate 6. The second mounting plate 14 has a through hole 15, and a turntable 16 is rotatably disposed at the through hole 15. The turntable 16 has a square through groove 17.

[0020] The column-beam rotation mechanism includes a placement block 18 rotatably mounted on the first mounting plate 13. The placement block 18 has a square placement groove 19 on the side facing the second mounting plate 14. The square placement groove 19 is correspondingly arranged with the square through groove 17. A rotary motor 20 for driving the placement block 18 to rotate is mounted on the first mounting plate 13.

[0021] Working principle:

[0022] Place both ends of the column beam to be straightened on the column beam placement assembly of the lifting plate 6. One end is embedded in the square placement slot 19 of the placement block 18 on the first mounting plate 13, and the other end passes through the square through slot 17 of the turntable 16 on the second mounting plate 14 to ensure stable placement. Start the lifting motor 11, which drives the lifting plate 6 to descend via the lifting screw 10. The guide rod 12 assists in guiding the column beam to be placed on the worktable 1. Stop lifting after placement. Start the displacement drive motor 8, which drives the transverse screw 7 to rotate, causing the moving seat 3 and the straightening hydraulic cylinder 4 to move laterally, so that the straightening pressure plate 5 is aligned with the bent part of the column beam. Start the straightening hydraulic cylinder 4 to apply pressure for correction.

[0023] When straightening other sides of the column beam is required, start the lifting motor 11, which drives the lifting plate 6 to rise via the lifting screw 10, raising the column beam to a safe height above the worktable 1 to avoid collision with the worktable 1 during subsequent rotation. After raising to the correct position, stop lifting and start the rotary motor 20 to drive the placement block 18 to rotate, causing the column beam to rotate synchronously, and the turntable 16 to rotate with the column beam. After rotating to the target angle, drive the lifting plate 6 to descend via the lifting screw 10, with the guide rod 12 assisting in guidance, and place the column beam on the worktable 1. Then repeat the alignment and operation steps until all bent parts are corrected.

[0024] This utility model features automated lifting, rotation, and straightening position adjustment, reducing manual intervention. The column and beam rotation does not require disassembly. Combined with precise mechanism control, it shortens the operation cycle and improves overall efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
