Description

Technical Field

[0001] This invention relates to the field of steel structure assembly technology, specifically to a vertical steel structure assembly device. Background Technology

[0002] In steel structure construction, steel structure assembly is a crucial step. Traditional steel structure assembly often employs a flat-laying method, where steel structural components are laid flat on the ground and assembled. However, this method has several drawbacks. Firstly, flat-laying assembly occupies a significant amount of space, especially in large-scale steel structure projects where the required site area is extremely limited. Secondly, after flat-laying assembly, the assembled structure needs to be erected upright, a process that is not only complex but also requires large lifting equipment, increasing construction costs and safety risks.

[0003] During the vertical assembly of steel structures, insufficient positioning accuracy, coupled with swaying during lifting and docking, can easily lead to deviations in the connection of upper and lower components. In addition, after the upper and lower steel structures are assembled and welded, residual weld slag may cover welding defects such as porosity, cracks, and incomplete penetration. These defects weaken the effective load-bearing area of ​​the weld and reduce the connection strength of the steel structure. Moreover, the local high temperature generated during welding can lead to welding stress after cooling, which may not only cause defects such as cracks and deformation of the welded parts, but also affect the structural performance. To address these issues, we propose a vertical steel structure assembly device. Summary of the Invention

The gear meshes with the rack.

[0011] Preferably, the U-shaped frame is equipped with a slag removal unit for removing weld slag from the joint of the two I-beams. The slag removal unit includes a T-shaped plate fixed to the top of the U-shaped frame, square plates fixed to one side of each of the two wing plates, racks fixed to one side of each of the two square plates, two rotating rods rotatably connected to one side of the T-shaped plate, gears fixed to one end of each of the two rotating rods, both gears meshing with racks, and gears fixed to the other end of each of the two rotating rods.

Beneficial effects

[0014] This invention provides a vertical assembly device for steel structures. Compared with the prior art, it has the following advantages:

[0015] (1) By setting up the fine-tuning alignment splicing mechanism, the bonding plate and wing plate automatically bond and contact with the two I-beams, so that the upper and lower I-beams can be automatically fine-tuned and corrected, and finally the joint of the two I-beams is aligned, reducing the error caused by manual alignment. The degree of automation is high. This precise adjustment capability can effectively avoid quality problems caused by the accumulation of splicing errors and improve the overall assembly quality of the steel structure.

[0016] (2) By setting up the slag removal unit, during the back-to-back movement of the bonding plate and the wing plate, the wing plate synchronously drives the slag removal sleeve to move downward, so that the slag removal sleeve slides over the joint of the two I-beams, thereby quickly removing the hot welding slag after welding. This allows defects such as porosity, cracks, and incomplete penetration that may occur during the welding process to be exposed, and the staff can repair these defects in time to avoid the effective bearing area of ​​the weld being weakened due to the defects being covered up, and further improve the assembly quality.

[0017] (3) By setting the intermittent hammering component, while the slag removal unit is working, the hammer can intermittently and repeatedly strike the I-beam. The hammering can not only make the weld and the surrounding metal vibrate, making the slag easier to fall off the weld, thus facilitating the subsequent slag removal mechanism to remove the slag more efficiently, but also the intermittent hammering can cause plastic deformation in the weld and the surrounding area, which helps to release the stress accumulated during the welding process, reduce the adverse effects of welding stress on the structural performance, and reduce the possibility of defects such as cracks and deformation in the weldment.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The present invention provides three technical solutions, specifically including the following embodiments:

[0029] Example 1

[0030] Please see Figure 1 and Figure 3 A steel structure vertical assembly device includes a base plate 1, a U-shaped frame 2 fixed to the top of the base plate 1, the U-shaped frame 2 providing support for the placement of I-beams 3, and two longitudinally spliced ​​I-beams 3 placed on the top of the U-shaped frame 2, such as... Figure 1 As shown, vertical assembly is performed, and the top of the base plate 1 is equipped with a fine-tuning alignment mechanism 4 that aligns the joints of the two I-beams 3.

[0031] The fine-tuning alignment seam mechanism 4 includes L-shaped plates 41 set on both sides of the I-beam 3. Each of the two L-shaped plates 41 has a bonding plate 42 fixed on one side. When the bonding plate 42 contacts the sides of the two I-beams 3, it can align the sides of the I-beams 3. Each of the two bonding plates 42 has four wing plates 43 fixed on it. When the wing plates 43 contact the front and back of the two I-beams 3, they align the front and back of the I-beams 3. When welding is required, the bonding plate 42 is separated from the I-beam 3 by a certain distance to reserve space for welding. The two L-shaped plates 41 are controlled by the drive assembly 44 to move in opposite directions or back directions. When the two L-shaped plates 41 move in opposite directions, they drive the bonding plate 42 and the wing plates 43 to contact and bond with the two I-beams 3, thus fine-tuning and aligning the I-beams 3.

[0032] The drive assembly 44 includes a mounting plate 441 fixed to the top of the base plate 1. A rotating plate 443 is rotatably connected to the top of the mounting plate 441 via a rotating shaft 442. Two rotating arms 444 are rotatably connected to the rotating plate 443 via pins. Two horizontal bars 445 are fixed to the top of the mounting plate 441. Two slide rails 446 are fixed to each of the two horizontal bars 445. Two movable plates 447 are arranged above the horizontal bars 445. Two slide blocks 448 are fixed to the bottom of each of the two movable plates 447.

[0033] The slide block 448 slides on the slide rail 446. Specifically, the slide block 448 slides horizontally left and right on the slide rail 446. One end of each of the two rotating arms 444 is rotatably connected to the moving plate 447 via a pin. Two mounting seats 449 are fixed on the top of the mounting plate 441. A cylinder 4410 is fixed on each of the two mounting seats 449. The cylinder 4410 is controlled by an external switch and is electrically connected to an external power supply. The output ends of the two cylinders 4410 are fixed to one side of the moving plate 447. An L-shaped frame 4411 is fixed on each of the two moving plates 447. The tops of the two L-shaped frames 4411 are fixed to the bottom of the L-shaped plate 41.

[0034] By setting up the fine-tuning alignment splicing mechanism 4, the bonding plate 42 and the wing plate 43 automatically bond and contact with the two I-beams 3, so that the upper and lower I-beams 3 can be automatically fine-tuned and corrected, and finally the joint of the two I-beams 3 is aligned. This reduces the error caused by manual alignment and has a high degree of automation. This precise adjustment capability can effectively avoid quality problems caused by the accumulation of splicing errors and improve the overall assembly quality of the steel structure.

[0035] Example 2

[0036] Based on Example 1, see Figure 7 and Figure 8As shown, the top of the base plate 1 is provided with a feeding assembly 5 for assembling the I-beams 3. The feeding assembly 5 includes a vertical plate 51 fixed to the top of the base plate 1. Two U-shaped rails 52 are fixed to one side of the vertical plate 51. A feeding seat 53 is slidably connected between the inner surfaces of the two U-shaped rails 52. The size of the feeding seat 53 is adapted to the U-shaped rails 52. A through groove 54 is provided through the top of the feeding seat 53. The through groove 54 allows the I-beams 3 to pass through, so that the upper I-beam 3 falls down and assembles with the lower I-beam 3. A cylinder 2 55 is fixed to one side of the vertical plate 51. The cylinder 2 55 is controlled by an external switch and electrically connected to an external power source. The output end of the cylinder 2 55 is fixed to one side of the feeding seat 53.

[0037] The loading seat 53 is equipped with an automatic opening mechanism 6. After the automatic opening mechanism 6 is opened, the I-beam 3 located in the through groove 54 automatically falls down and splices with the bottom I-beam 3. The automatic opening mechanism 6 includes a motor 61 fixed to the top of the loading seat 53. The motor 61 is a three-phase asynchronous motor that can rotate in both directions. It is controlled by an external switch and electrically connected to an external power supply. A transverse groove 62 is opened on one side of the loading seat 53. A sliding door 63 is slidably connected to the inner surface of the transverse groove 62. After the sliding door 63 is opened, the upper I-beam 3 can fall down. A rack 64 is fixed on one side of the sliding door 63. A gear 65 is fixed to the output end of the motor 61. The gear 65 meshes with the rack 64.

[0038] By setting the feeding component 5, the upper I-beam 3 can be automatically unloaded and the I-beam 3 can be limited to prevent it from swaying and tipping over during assembly.

[0039] Example 3

[0040] Based on Example 2, see Figure 2 , Figure 4 , Figure 5 , Figure 6As shown, the U-shaped frame 2 is equipped with a slag removal unit 7 for removing slag from the joint of the two I-beams 3. The slag removal unit 7 includes a T-shaped plate 71 fixed to the top of the U-shaped frame 2, square plates 72 fixed to one side of each of the two wing plates 43, and racks 73 fixed to one side of each of the two square plates 72. Two rotating rods 74 are rotatably connected to one side of the T-shaped plate 71. Gears 75 are fixed to one end of each of the two rotating rods 74 and mesh with racks 73. Gears 76 are fixed to the other end of each of the two rotating rods 74. Two rotating rods 77 are rotatably connected to one side of the T-shaped plate 71. Gears 78 are fixed to one end of each of the two rotating rods 77 and mesh with gears 78. When gears 76 rotate, they drive gears 78 to rotate in reverse. Gears 78 are fixed to the other end of each of the two rotating rods 77. A slag removal sleeve 710 is slidably connected to the I-beam 3. The slag removal sleeve 710 is adapted to the size of the I-beam 3. When the slag removal sleeve 710 moves up and down through the weld, it can remove the weld slag. Two bent rods 711 are fixed on one side of the slag removal sleeve 710. The bottom end of each of the two bent rods 711 is fixed with a rack 3 712. Both racks 3 712 mesh with gear 59. Connecting plates 713 are fixed on both sides of the slag removal sleeve 710. Vertical rods 714 are fixed on the top of each of the two connecting plates 713. Two vertical pipes 715 are fixed at the bottom of the feeding seat 53. The top ends of the two vertical rods 714 extend into the interior of the vertical pipes 715 and slide in the vertical pipes 715. A limiting plate is fixed to the top end of the vertical rods 714. The limiting plate slides in the vertical pipes 715. The setting of the limiting plate can prevent the vertical rods 714 from sliding out of the vertical pipes 715.

[0041] With the slag removal unit 7 in place, as the bonding plate 42 and the wing plate 43 move in opposite directions, the wing plate 43 simultaneously drives the slag removal sleeve 710 to move downwards, allowing the slag removal sleeve 710 to slide over the joint of the two I-beams 3, thereby quickly removing the hot weld slag after welding. This exposes defects such as porosity, cracks, and incomplete penetration that may occur during the welding process, allowing workers to repair these defects in a timely manner and preventing the effective load-bearing area of ​​the weld from being weakened due to the defects being covered up, thus further improving the assembly quality.

[0042] The rotating rod 77 is equipped with an intermittent striking assembly 8 for intermittently striking the I-beam 3. The intermittent striking assembly 8 includes a rotating wheel 81 fixed on the rotating rod 77, a horizontal plate 82 fixed on one side of the T-shaped plate 71, a swing fork 83 rotatably connected to the top of the horizontal plate 82 via a pin, a triangular arc plate 84 fixed on the rotating wheel 81, and a roller 85 rotatably connected to one end of the swing fork 83. The side surface of the roller 85 contacts the side surface of the triangular arc plate 84. The triangular arc plate 84 allows the rotating wheel 81 to intermittently contact the roller 85 during rotation, thereby driving the swing fork 83 to swing intermittently.

[0043] An arc-shaped rack 86 is fixed on the triangular arc plate 84. A connecting seat 87 is fixed on one side of the T-shaped plate 71. A groove 88 is provided on the top of the connecting seat 87. A moving block 89 is slidably connected inside the groove 88. A straight rack 810 is fixed on one side of the moving block 89. The straight rack 810 meshes with the arc-shaped rack 86. A spring 811 is fixed between one side of the moving block 89 and the inner wall of the groove 88. The spring 811 is used to drive the moving block 89 to reset. An L-shaped rod 812 is fixed on the top of the moving block 89. One side of the L-shaped rod 812 rotates... The moving connection has a connecting column 813, which can be rotated manually. The friction between the connecting column 813 and the L-shaped rod 812 is relatively large. After the connecting column 813 rotates, it can remain stable and stationary, keeping the striking hammer 815 horizontal and rotating without being affected by the weight of the striking hammer 815. When the striking hammer 815 is not in use, it can be rotated to a vertical position and put away. When it is needed, it can be rotated to a horizontal position. A swing rod 814 is fixed on the connecting column 813. The striking hammer 815 is fixed to one end of the swing rod 814. The striking hammer 815 can intermittently strike the I-beam 3.

[0044] By setting the intermittent striking component 8, while the slag removal unit 7 is working, the striking hammer 815 can intermittently reciprocate striking the I-beam 3. The striking not only causes vibration in the weld and the surrounding metal, making it easier for the slag to fall off the weld and thus facilitating more efficient removal of the slag by the subsequent slag removal mechanism, but also causes plastic deformation in the weld and the surrounding area, which helps to release the stress accumulated during the welding process, reduce the adverse effects of welding stress on structural performance, and reduce the possibility of defects such as cracks and deformation in the weldment.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0046] During operation, one I-beam 3 is placed on top of the U-shaped frame 2, and another I-beam 3 is hoisted into the through channel 54 using hoisting equipment. At this time, the sliding door 63 is closed. Cylinder 2 55 is activated, pushing the loading seat 53 to move above the I-beam 3. Then, motor 61 is activated, which drives gear 1 65 to rotate. Gear 1 65 drives rack 1 64 to move, and rack 1 64 drives the sliding door 63 to open, allowing the upper I-beam 3 to fall onto the top of the lower I-beam 3 for assembly. Activating cylinders 4410 causes them to retract, moving the movable plate 447, which in turn rotates and retracts the rotating arm 444, causing the rotating plate 443 to rotate, which in turn moves the other movable plate 447. This causes the two bonding plates 42 and multiple flanges 43 to retract and move, bringing them closer to the two I-beams 3. This allows for fine-tuning and alignment of the joints of the I-beams 3, facilitating the next step of welding and assembly. After welding at the joint of part 3, the two cylinders 4410 are activated to open the joint, which in turn drives the bonding plate 42 and multiple wing plates 43 to move in opposite directions. The wing plates 43 then drive the rack 73 to move, which in turn drives the gear 75 to rotate. The gear 75 drives the gears 76 and 78 to rotate, which in turn drives the gear 79 to rotate in the opposite direction. The gear 79 then drives the rack 712, the bending rod 711, and the slag removal sleeve 710 to move downwards, thus allowing the slag removal sleeve 710 to weld. The welding slag is removed. When the rotating rod 77 rotates, it drives the rotating wheel 81 to rotate. Then the rotating wheel 81 drives the triangular arc plate 84 to intermittently contact the roller 85, which in turn drives the swing fork 83 to swing intermittently around the pin shaft. Then the arc rack 86 drives the straight rack 810 and the moving block 89 to move intermittently. Then the swing hammer 815 intermittently reciprocates to strike the I-beam 3. After the strike, it helps to release the stress accumulated during the welding process and reduce the adverse effects of welding stress on the structural performance.

[0047] The embodiments of the invention have been described in detail above, but the content described is only a preferred embodiment of the invention and should not be considered as limiting the scope of the invention. All equivalent changes and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
