[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, columns, trusses, and other components made of shaped steel and steel plates. These components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, and high-rise buildings. However, steel structure components often require pre-processing operations such as drilling, welding, or riveting during fabrication. Existing methods typically use cranes for tilting and fixing. When components are lifted and rotated in the air, they are prone to swaying and tilting, posing a risk of falling. This is detrimental to both fixing and pre-processing.

The other end of the lead screw 5 is drively connected to a first motor 6, which is fixedly connected to the platform 1. Installation grooves are respectively provided on opposite side walls of the sliding groove 3, and a lifting assembly is fixedly installed in the installation groove. The lifting assembly is detachably connected to the bottom surface of the component 7.

[0033] This invention uses a laterally movable pushing unit to push component 7 into a flipping unit, thus fixing component 7 and facilitating its processing. Simultaneously, to facilitate the flipping of component 7, one side of the lifting assembly, fixedly connected within the mounting slot, is used for axial flipping. Furthermore, individual lifting assemblies on different sides can be used to achieve flipping in different directions. Moreover, the pushing unit can simultaneously use two lifting assemblies to upright component 7, facilitating upright processing.

The hydraulic cylinder 10 can be used to position one end of the component 7 in the fixed frame 8.

[0035] Further optimization of the scheme: the pressing assembly includes a pressing plate 11, one end of which is rotatably connected to one side of the fixed frame 8. Sliding columns 12 are symmetrically fixedly connected to both sides of the pressing plate 11. First springs 13 are fixedly connected to both sides of the sliding columns 12.

[0036] Furthermore, the buffer block 14 is made of elastic rubber, polyurethane, or silicone, which can both relieve the pressure on the component 7 through the first spring 13 and limit the sliding column 12 by utilizing the compression limit of the buffer block 14.

[0037] Further optimize the plan, by Figure 3 As shown, the flipping unit includes a restraint frame 15, which is a C-shaped frame structure similar in shape to the fixed frame 8. Screw holes are provided on opposite sidewalls of the restraint frame 15, and side-top components are screwed into these holes. The side-top components are detachably connected to the side of component 7. A cover plate 16 is rotatably connected to the top surface of the restraint frame 15 via a hinge. The hinge is an elastic hinge, capable of providing a certain rebound force to drive the cover plate 16 when closed. The bottom surface of the cover plate 16 is detachably connected to the top surface of the restraint frame 15. A clearance hole is provided on one side of the restraint frame 15, and a side-push component is fixedly installed within the clearance hole. The side-push component is detachably connected to component 7. A rotating component is fixedly connected to the bottom surface of the restraint frame 15, and a lifting block 17 is fixedly connected to the bottom surface of the rotating component. A lifting component is fixedly connected to the side of the lifting block 17, and the lifting component is fixedly connected to the bottom surface of the platform 1. The lifting component allows the restraint frame 15 to slide into the adjustment hole 2, achieving vertical fixation of component 7.

[0038] Furthermore, a clearance clearance is provided at one end of the bottom surface of platform 1 near the lifting block 17. The adjustment hole 2, the lifting block 17 and the lifting component are all located at the clearance clearance position on the bottom surface of platform 1, which facilitates the operation of the overall structure.

[0039] Furthermore, the lifting component is a hydraulic cylinder, an electric cylinder, or a pneumatic cylinder, which are existing technologies and will not be described in detail here.

[0040] Further optimize the plan, by Figure 6 As shown, the side-top assembly includes a screw cylinder 18, which is open at both ends. One end of the screw cylinder 18 is fixedly connected to an annular plate 19. The inner wall of the annular plate 19 has several square holes spaced at equal intervals. The side wall of the screw hole also has snap-fit ​​holes that match the square holes. A snap-fit ​​assembly is fixedly connected to each square hole. One end of the snap-fit ​​assembly extends out of the side of the annular plate 19 and is detachably connected to the snap-fit ​​hole on the side wall of the screw hole, thus stopping the side-top assembly. The other end of the snap-fit ​​assembly slides in contact with a slide rod 20. One end of the slide rod 20 is fixedly connected to a screw cap 21, which is screwed to the inner wall of the screw hole.

[0041] Furthermore, a wrench assembly is required to rotate the screw barrel 18 and the screw cap 21. Two grooves are symmetrically provided about the center of the screw barrel 18 at the end away from the ring plate 19. At the same time, two wrench holes and two clearance holes are symmetrically provided about the center of the end face of the screw cap 21. The wrench assembly includes levers that fit into the grooves and wrench holes respectively. One end of all levers is fixedly connected to a handle. The side top assembly can be turned by using the different depths of the lever insertion.

[0042] Further optimizing the design, the snap-fit ​​assembly includes a snap-fit ​​block 22 and a drive block 23. A fixing rod 24 is fixedly connected between the snap-fit ​​block 22 and the drive block 23. A second spring 25 is sleeved on the outer side of the fixing rod 24. A gap is provided between one end of the second spring 25 and the snap-fit ​​block 22, increasing the extension and retraction distance of the snap-fit ​​block 22 and preventing interference. One end of the second spring 25 is fixedly connected to the side wall of the square hole, and the second spring 25 provides a restoring force to the snap-fit ​​block 22, facilitating the snap-fit ​​block 22 to disengage from the snap-fit ​​hole. The end of the slide rod 20 away from the screw cap 21 has a tapered inclined surface, and the side of the drive block 23 away from the snap-fit ​​block 22 has an arc-shaped driving surface that matches and slides in contact with the inclined surface. The slide rod 20 presses against the drive block 23 to push the snap-fit ​​block 22 into the snap-fit ​​hole.

[0043] Furthermore, the sides of the drive block 23 and the snap-fit ​​block 22 are slidably connected to the inner wall of the square hole to prevent the drive block 23 and the snap-fit ​​block 22 from rotating.

[0044] Further optimize the plan, by Figure 8 As shown, the side-pushing assembly includes a push plate 26. One side of the push plate 26 is detachably connected to the component 7. The side of the push plate 26 is slidably connected to the inner wall of the restraint frame 15. A telescopic rod 27 is fixedly connected to the other side of the push plate 26. A fixing plate 28 is fixedly connected to one end of the telescopic rod 27. The fixing plate 28 is fixedly connected to the side wall of the clearance hole. By using the telescopic rod 27 to push the push plate 26, the position of one end of the component 7 within the restraint frame 15 can be adjusted.

[0045] Furthermore, the telescopic rod can be a hydraulic cylinder, an electric cylinder, or a pneumatic cylinder, which are existing technologies and will not be described in detail here.

[0046] Further optimize the plan, by Figure 5 As shown, the rotating assembly includes a base 29 with a blind hole on its bottom surface. The bottom surface of the base 29 is rotatably connected to the top surface of the supporting block 17. A gear 30 is fixedly connected to the top surface of the inner cavity of the base 29, and the gear 30 meshes with a drive wheel 31. The diameter of the drive wheel 31 is smaller than the diameter of the gear 30. Preferably, the diameter of the drive wheel 31 is 0.2-0.5 times that of the gear 30 to facilitate the adjustment of the rotation speed of the base 29. A second motor 32 is driven by the drive wheel 31 and is embedded in the top surface of the supporting block 17 and fixedly connected to the supporting block 17.

[0047] The design is further optimized so that the outer contour of the restraint frame 15 is square. The adjustment hole 2 is adapted to the outer side of the restraint frame 15 and is slidably connected to the outer side of the restraint frame 15. Several corner grooves 33 are equally spaced on the side of the adjustment hole 2, which are adapted to the corners of the restraint frame 15 and are slidably connected. By using the corner grooves 33 to slide with the corners of the restraint frame 15, both the vertical guidance of the restraint frame 15 and the lateral support and fixation of the restraint frame 15 are realized.

[0048] The design is further optimized so that the lifting assembly includes a lifting block 34. The side of the lifting block 34 slides in contact with the side of the mounting groove. Electric cylinders 35 are fixedly connected to both sides of the lifting block 34. The electric cylinders 35 are fixedly connected to the side wall of the mounting groove. A guide angle is provided on the top surface of the lifting block 34 near the pushing unit. The top surface of the lifting block 34 is detachably connected to the bottom surface of the component 7. The lifting assembly can realize the function of flipping and standing the component 7 by using the individual lifting and combined lifting of the electric cylinders 35.

[0049] The working process of this embodiment is as follows:

[0050] The platform 1 of the present invention is fixedly set on the ground. The component 7 is placed on the slide groove 3 on the top surface of the platform 1 using a lifting tool. One end of the component 7 is inserted into the fixed frame 8, and the other end of the component 7 is aligned with the restraint frame 15. The first motor 6 is started to drive the lead screw 5 to rotate, which in turn drives the slider 4 to move the fixed frame 8 toward the restraint frame 15. The horizontal fixation of the component 7 is achieved by the compression of the restraint frame 15 and the fixed frame 8. At the same time, the push ring plate 19 can be pushed to abut against the side of the component 7 by using the wrench assembly to tighten the screw cylinder 18, which reduces the probability of the component 7 moving randomly.

[0051] In order to pre-process different sides of component 7, any one of the lifting components needs to be activated. The lifting block 34 is pulled up by the pulling force of the electric cylinder 35 and extended out of the top surface of the platform 1. Then, with manual assistance, it is flipped. At the same time, before flipping, the first motor 6 needs to be reversed to disengage the pushing unit from component 7. Then, the side pushing component is used to push component 7 away from the flipping unit.

[0052] Furthermore, in order to reduce interference during the flipping process of component 7, several clearance grooves are opened on the side wall of the slide 3 to avoid the attachments machined on component 7, so as to facilitate the flipping of component 7.

[0053] To ensure that the side surfaces of component 7 are fully exposed, facilitating pre-processing of the peripheral surfaces of component 7 and reducing the frequency of horizontal flipping, one end of component 7 is inserted into the fixed frame 8. The first motor 6 is activated, using the slider 4 to drive the fixed frame 8 to push component 7 towards the restraint frame 15. When one end of component 7 passes the mounting groove, the electric cylinder 35 is activated, and the two lifting blocks 34 simultaneously lift up. At this point, one end of component 7 will tilt upwards, and the tilted component 7 will penetrate into the restraint frame 15 and flip the cover plate 16. The cover plate 16 uses the spring force of the hinge to restrain the component. 7. Provide auxiliary support and continue pushing until component 7 is nearly vertical. At this point, start the hydraulic cylinder 10 to push the bottom of component 7 into the restraint frame 15. Use the wrench assembly to abut the side top assembly against the two sides of component 7 to improve the stability of component 7. Then, use the wrench assembly to tighten the screw cap 21. The screw cap 21 rotates and drives the slide rod 20 to go deeper into one end of the screw barrel 18. The push drive block 23 moves to the periphery of the screw barrel 18, that is, pushes the snap block 22 out of the ring plate 19 and snaps into the snap hole, preventing component 7 from tipping over.

[0054] Then, start the lifting mechanism to move the lifting block 17 down, which will drive the restraint frame 15 down. At the same time, the component 7 set in the restraint frame 15 will also move down. Start the telescopic rod 27 to push the push plate 26 to abut the component 7 against the side wall of the adjustment hole 2, thus achieving a stable fixation of the component 7. At this time, various pre-processing operations can be performed on the side of the component 7.

[0055] After component 7 is processed, the lifting device is activated to lift block 17 upward, which in turn drives the restraint frame 15 upward. At the same time, component 7, which is set inside the restraint frame 15, also moves upward until it returns to its initial state. At this time, the hydraulic cylinder 10 is activated to push the lower end of the vertical component 7, and then the telescopic rod 27 is activated to gradually retract. Then, the cover plate 16 above pushes component 7 under the action of the hinge, realizing the slow tilting of component 7 towards the pushing unit. When one end of component 7 overlaps the top of the fixed frame 8, the first motor 6 is activated to gradually pull the slider 4 back, which will slowly lower component 7 until one end of component 7 lands on the pressure plate 11. The elastic force of the first spring 13 received by the pressure plate 11 is used to buffer the force of component 7, realizing the smooth fall of component 7.

[0056] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
