[0031] Embodiment

[0032] The present invention provides a steel member 1 correction device, as Figures 1-8 shown, including a frame 17. The frame 17 is a steel frame structure, which is used to carry the overall structure and maintain sufficient rigidity. Two pairs of support structures are respectively installed on the opposite sides of the frame 17. The support structures have the same structure. Each support structure includes at least three support arms 4 and a mounting base 2. The mounting base 2 is fixed to the side wall of the frame 17 by bolts or welding. At least three support arms 4 are arranged around the outer side wall of the mounting base 2. The support arms 4 are all installed on the outer side wall of the mounting base 2 by bolts or axles and lugs. Two adjusting mechanisms respectively corresponding to the two groups of support structures are arranged in the frame 17. The adjusting mechanism is used to control the synchronous movement of several support arms 4 in the same support structure; to ensure that the steel member 1 is evenly stressed under the support of at least three support arms 4 and avoid local deformation.

[0033] A limit piece 5 for assembling the steel component 1 is installed on the free end of the support arm 4, and a locking piece for locking the steel component 1 is installed in the "匚"-shaped area of ​​the limit piece 5; the limit piece 5 is designed by a rotating mounting frame 6 and a limit screw 25, and the angle of the "匚"-shaped area can be adjusted to adapt to steel components 1 with different cross-sectional shapes (such as H-shaped steel, I-shaped steel).

[0034] A positioning mechanism is provided on the side wall of the frame 17. When the two steel members 1 are connected to each other, the positioning mechanism is used to locate the installation position of the two steel members 1. The limit groove and the sliding structure 22 of the positioning frame 9 allow the support arm 4 to fine-tune the position; the level 21 monitors the levelness in real time to ensure that the butt joint surface is flush.

[0035] In some technical solutions of the present invention, the adjustment mechanism includes a guide frame 3, and the specific structure of the guide frame 3 includes at least three guide rods 15 and two limit platforms. The three guide rods 15 are installed in the two limit platforms in a herringbone shape, and the three guide rods 15 are fixedly connected to the limit platforms by welding or threaded connection. The guide rod 15 is an optical axis, and one of the limit platforms in the guide frame 3 is fixed to the side wall of the mounting seat 2 by bolts. An adjustment platform 8 is slidably provided in the guide frame 3, and three guide holes adapted to the guide rods 15 are opened on the side wall of the adjustment platform 8, and the guide rods 15 extend outward after passing through the guide holes. A plurality of adjustment arms 7 corresponding to the support arms 4 are provided on the adjustment platform 8 through the rotation of the shaft rod; the adjustment arm 7 is connected to the corresponding support arm 4 through the rotation of the shaft rod. A screw rod 12 is provided in the guide frame 3 through a bearing, and the screw rod 12 is threadedly connected with an internal threaded hole provided in the middle of the adjustment platform 8; the screw rod 12 passes through the mounting seat 2 and is placed in the frame 17; that is, the free end of the screw rod 12 is rotatably arranged in the frame 17. The adjustment platform 8 is driven to move by the screw rod 12, and the multiple groups of adjustment arms 7 are driven to move in linkage, so that the support arms 4 are synchronously extended and retracted, ensuring that the steel member 1 is evenly stressed and local deformation is avoided.

[0036] A drive structure is installed in the frame 17, and the drive structure is connected in transmission with the screw rods 12 located in the two adjusting mechanisms. The two screw rods 12 can be moved synchronously or independently in one direction by the drive structure.

[0037] In some technical solutions of the present invention, the driving structure includes a first driving motor 16, which is installed in a frame 17; driving gears 18 are installed on the outer walls of the two screw rods 12, one of which is connected to the driving motor in a transmission manner, and a transmission shaft 14 is passed through the frame 17, and driven gears 13 meshing with the driving gear 18 are installed at both ends of the transmission shaft 14. The above structure realizes the transmission connection of the two screw rods 12 respectively located in the adjustment mechanism through the gears and the transmission shaft 14, and can correct the two sides of the two mutually spliced ​​steel structures at the same time, ensuring that when the steel structure is corrected by this structure, the part of the steel structure to be corrected can be deflected in a predetermined direction by a fixed angle, and ensuring that when the steel structure is corrected in this structure, its correction points remain parallel to each other, thereby improving the correction effect.

[0038] In some technical solutions of the present invention, the driving structure includes two second driving motors 24, and the two second driving motors 24 are respectively connected to the two screw rods 12. The working states of the two supporting structures in different working environments can be adjusted respectively, that is, one of the supporting structures is fixed on the calibrated steel structure, and the other supporting structure is used to support the steel structure connected to the supporting structure, so as to perform alignment operation on the two mutually spliced ​​steel structures, which is convenient for supporting the steel structures, and the two independent moving supporting structures can independently support the two steel structures and independently adjust the two unconnected steel structures, thereby improving the correction efficiency and quality of the steel structure adjustment of the present structure. The adjusting platform 8 is driven to move by the screw rod 12, which drives the linkage of multiple groups of adjusting arms 7, realizes the synchronous extension and retraction of the supporting arms 4, ensures that the steel member 1 is evenly stressed, avoids local deformation, and can also achieve the purpose of self-locking.

[0039] In some technical solutions of the present invention, the correction mechanism includes a correction frame 9, which is installed between two support arms 4 arranged opposite to each other in two support structures, and both ends of the correction frame 9 are provided with limit grooves adapted to the support arms 4, and sliding structures 22 are installed in the limit grooves, and the sliding surfaces of the sliding structures 22 are on the side walls of the support arms 4. On the sliding structures 22, a level 21 is installed on the side walls of the correction frame 9 along the extension direction thereof. The limit grooves and the sliding structures 22 of the correction frame 9 allow the support arms 4 to fine-tune their positions; the level 21 monitors the levelness in real time to ensure that the docking surfaces are flush, and improve the accuracy of docking and correction.

[0040] In some technical solutions of the present invention, a mounting bracket 6 is installed on the free end of the support arm 4. The limiting member 5 has a "C"-shaped frame structure, and the limiting member 5 is rotatably arranged in the mounting bracket 6. An internal threaded hole is provided on the side wall of the limiting member 5, and a limiting screw rod 25 threadedly connected thereto is arranged in the internal threaded hole. The limiting screw rod 25 is rotatably connected to the outer side wall of the limiting member 5 through a load-bearing bearing. By designing the limiting screw rod 25, the angle of the "C"-shaped area of the limiting member 5 can be adjusted to adapt to steel members 1 with different cross-sectional shapes (such as H-shaped steel and I-shaped steel).

[0041] Preferably, a limiting plate 26 is fixedly installed on the limiting screw rod 25. It is used to increase the contact area between the above structure and the steel member 1.

[0043] In some technical solutions of the present invention, a guide groove 23 is opened on the side wall of the alignment frame 9 along its extending direction. Two sliding seats 19 are slidably arranged in the guide groove 23, and the two sliding seats 19 are respectively connected to the body of the first hydraulic cylinder 10. The first hydraulic cylinder 10 arranged in this way can correct a part of the steel structure to be corrected along the extending direction of the alignment frame 9, improving the correction range of this structure.

[0044] In some technical solutions of the present invention, a locking mechanism is arranged in the alignment frame 9. The locking mechanism is detachably connected to the two support arms 4. The locking structure includes a two-way push rod 20 installed in the alignment frame 9. Locking rods are slidably arranged on both sides of the alignment frame 9. A number of locking holes adapted to the locking rods are opened on the outer side wall of the support arm 4 along its extending direction. An electromagnetic lock is installed at the end of the locking rod. The two-way push rod 20 drives the locking rod to engage with the locking hole of the support arm 4, and the electromagnetic lock further fixes it to prevent deviation during the docking process, affecting the correction accuracy of this structure for the steel structure.

[0045] In some technical solutions of the present invention, the number of alignment mechanisms is several groups, and several groups of alignment mechanisms are arranged around the support structure. The alignment frames 9 are arranged in multiple directions (such as orthogonal or circular layout) to correct complex angular deviations (such as space truss nodes).

[0046] The correction process of this structure for the steel member:

[0047] Place the steel member 1 to be corrected in the "C"-shaped area of the limiting member 5, rotate the limiting screw rod 25 to clamp it, and fix it through the bolts arranged in the locking member and the limiting plate 26.

[0048] Adjust the position of the support arm 4: the drive motor drives the screw 12 through gear transmission or directly drives the adjustment platform 8 to move along the guide rod 15, and pushes the adjustment arm 7 to make the support arm 4 extend synchronously to fit the contour of the steel component 1.

[0049] Angle and position correction stage

[0051] Height adjustment: The first hydraulic cylinder lifts the support platform 11 to a predetermined height, and the sliding seat 19 is positioned along the guide groove 23 to ensure that the butt end faces of the steel member 1 are flush, and to perform fine adjustments on the two mutually spliced ​​steel structures.

[0052] Rigid locking: The bidirectional push rod 20 is inserted into the locking hole of the support arm 4, and the electromagnetic lock is energized and fixed to prevent displacement during the docking process.

[0053] Docking operation phase

[0054] Synchronous correction (single motor solution): The driving motor synchronously rotates the screws 12 on both sides through the transmission shaft 14 to align the end faces of the two steel components 1.

[0055] Independent correction (dual motor solution): Control the displacement of the support arms 4 on both sides respectively, adjust the angle of the steel member 1 on one side, and is suitable for the correction of asymmetric splicing.

[0056] Correction is completed: the locking mechanism is released, the correction frame 9 is moved out, and the welding or riveting process is started.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
