Description

Technical Field

[0001] The present invention relates to the technical field of steel structure assembly, and specifically to an upright assembly device for steel structures. Background Art

[0002] In the construction of steel structure projects, the assembly of steel structures is an important link. For traditional steel structure assembly, a flat laying assembly method is mostly adopted, that is, steel structure components are laid flat on the ground for splicing. However, this method has many defects. On the one hand, the flat laying assembly occupies a large amount of site space, especially in large-scale steel structure projects, which requires a very large site area; on the other hand, after the flat laying assembly is completed, the assembled structure needs to be erected as a whole. This process is not only complex in operation, but also requires the cooperation of large lifting equipment, increasing the construction cost and safety risks.

[0003] During the vertical assembly process of steel structures, due to insufficient positioning accuracy and the shaking during lifting and docking, it is easy to cause deviations in the docking of upper and lower components during the splicing process. In addition, after the upper and lower steel structures are assembled and welded, the remaining welding slag may cover welding defects such as pores, cracks, and incomplete penetration. These defects will weaken the effective bearing area of the weld seam, reduce the connection strength of the steel structure, and the local high temperature generated during the welding process will cause welding stress after cooling, which may not only cause defects such as cracks and deformation of the welded parts, affecting the structural performance. For this reason, we propose an upright assembly device for steel structures to solve the above problems. Summary of the Invention

[0014] The present invention provides a steel structure upright assembling device. Compared with the prior art, the following beneficial effects are achieved:

[0015] (1) Through the setting of the fine adjustment and alignment of the joint mechanism, the fitting plate and the flange plate are automatically brought into contact with the two I-beams, so that the upper and lower two I-beams are automatically fine-adjusted and corrected, and finally the joints of the two I-beams are aligned, reducing the error generated by manual alignment. The degree of automatic assembly is high. This precise adjustment ability can effectively avoid quality problems caused by the accumulation of splicing errors and improve the overall assembly quality of the steel structure.

[0016] (2) Through the setting of the welding slag removal unit, during the process of the fitting plate and the wing plate moving away from each other, the wing plate synchronously drives the slag removal sleeve to move downward, making the slag removal sleeve slide over the joint of the two I-beams, thereby quickly removing the hot welding slag after welding. This enables defects such as pores, cracks, and incomplete penetration that may occur during the welding process to be exposed, allowing workers to repair these defects in a timely manner, avoiding the weakening of the effective load-bearing area of the weld due to the concealment of defects, and further improving the assembly quality.

[0017] (3) Through the setting of the intermittent knocking component, while the welding slag removal unit is working, the knocking hammer can intermittently reciprocally knock the I-beam. The knocking can not only make the metal around the weld and the weld vibrate, making the welding slag easier to fall off from the weld, thus facilitating the subsequent welding slag removal mechanism to remove the welding slag more efficiently, but also the intermittent knocking can cause plastic deformation in the weld and its nearby areas, helping to release the stress accumulated during the welding process, reducing the adverse effects of welding stress on the structural performance, and reducing the possibility of defects such as cracks and deformations in the welded parts.

Detailed implementation manners

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

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

[0029] Embodiment 1

[0030] Please refer to Figure 1 and Figure 3 , a vertical assembly device for steel structures, including a bottom plate 1. A U-shaped frame 2 is fixed on the top of the bottom plate 1. The U-shaped frame 2 provides support for the placement of I-beams 3. Two longitudinally spliced I-beams 3 are placed on the top of the U-shaped frame 2. The I-beams 3 are vertically assembled as shown in Figure 1 . A fine-tuning alignment and joint mechanism 4 for aligning the joints of the two I-beams 3 is provided on the top of the bottom plate 1;

[0031] The fine-tuning alignment and seam splicing mechanism 4 includes L-shaped plates 41 arranged on both sides of the I-beam 3. On one side of each of the two L-shaped plates 41, there is a fitting plate 42 fixed. When the fitting plates 42 contact the side surfaces of the two I-beams 3, the side surfaces of the I-beams 3 can be aligned. On each of the two fitting plates 42, there are four wing plates 43 fixed. When the wing plates 43 contact the front and rear surfaces of the two I-beams 3, the front and rear surfaces of the I-beams 3 are aligned. When welding is required, the fitting plates 42 are separated from the I-beams 3 by a certain distance to reserve space for welding. The two L-shaped plates 41 are controlled by the driving assembly 44 to move towards or away from each other. When the two L-shaped plates 41 move towards each other, they drive the fitting plates 42 and the wing plates 43 to contact and fit with the two I-beams 3, and the I-beams 3 are finely adjusted and moved to be aligned.

[0032] The driving assembly 44 includes a mounting plate 441 fixed to the top of the base plate 1. The top of the mounting plate 441 is rotatably connected to a rotating plate 443 through a rotating shaft 442. On the rotating plate 443, there are two rotating arms 444 rotatably connected through pin shafts. On the top of the mounting plate 441, there are two cross bars 445 fixed. On each of the two cross bars 445, there are two slide rails 446 fixed. Above the cross bars 445, there are two moving plates 447 arranged. On the bottom of each of the two moving plates 447, there are two sliding seats 448 fixed.

[0033] The sliding seats 448 slide on the slide rails 446. Specifically, the sliding seats 448 slide horizontally left and right on the slide rails 446. One end of each of the two rotating arms 444 is rotatably connected to the moving plate 447 through a pin shaft. On the top of the mounting plate 441, there are two mounting seats 449 fixed. On each of the two mounting seats 449, there is a cylinder 4410 fixed. 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. On each of the two moving plates 447, there is an L-shaped frame 4411 fixed. The tops of the two L-shaped frames 4411 are fixed to the bottom of the L-shaped plate 41.

[0034] Through the setting of the fine-tuning alignment and seam splicing mechanism 4, by using the automatic contact and fitting of the fitting plates 42 and the wing plates 43 with the two I-beams 3, the upper and lower two I-beams 3 are automatically finely adjusted and corrected. Finally, the joints of the two I-beams 3 are aligned, reducing the errors generated by manual alignment. The degree of automated assembly is high. This precise adjustment ability can effectively avoid quality problems caused by the accumulation of splicing errors and improve the overall assembly quality of the steel structure.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, refer to Figure 7 and Figure 8As shown in the figure, a feeding component 5 for driving the assembly of the I-beam 3 is arranged on the top of the bottom plate 1. The feeding component 5 includes a vertical plate 51 fixed on the top of the bottom plate 1. Two U-shaped rails 52 are fixed on 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 feeding seat 53 is adapted to the size of the U-shaped rails 52. A through groove 54 is formed through the top of the feeding seat 53. The setting of the through groove 54 allows the I-beam 3 to pass through, so that the upper I-beam 3 can fall and be assembled with the lower I-beam 3. A cylinder two 55 is fixed on one side of the vertical plate 51. The cylinder two 55 is controlled by an external switch and is electrically connected to an external power supply. The output end of the cylinder two 55 is fixed to one side of the feeding seat 53.

[0037] An automatic opening mechanism 6 is arranged inside the feeding seat 53. After the automatic opening mechanism 6 is opened, the I-beam 3 located in the through groove 54 automatically falls and is spliced with the I-beam 3 at the bottom layer. The automatic opening mechanism 6 includes a motor 61 fixed on the top of the feeding seat 53. The motor 61 is a three-phase asynchronous motor that can rotate forward and backward. It is controlled by an external switch and is electrically connected to an external power supply. A horizontal groove 62 is formed on one side inside the feeding seat 53. A moving door 63 is slidably connected to the inner surface of the horizontal groove 62. After the moving door 63 is opened, the upper I-beam 3 can fall. A rack one 64 is fixed on one side of the moving door 63. The output end of the motor 61 is fixed with a gear one 65. The gear one 65 meshes with the rack one 64.

[0038] Through the setting of the feeding component 5, the upper I-beam 3 can be automatically fed, and the I-beam 3 can be limited to prevent the I-beam 3 from swinging and tipping during assembly.

[0039] Embodiment 3

[0040] Based on Embodiment 2, refer to Figure 2 、 Figure 4 、 Figure 5 、 Figure 6As shown in the figure, a slag removal unit 7 for removing the welding slag at the joint of two I-beams 3 is provided on the U-shaped frame 2. The slag removal unit 7 includes a T-shaped plate 71 fixed to the top of the U-shaped frame 2. Square plates 72 are fixed to one side of each of the two wing plates 43. Rack two 73 is fixed to one side of each of the two square plates 72. Two first rotating rods 74 are rotatably connected to one side of the T-shaped plate 71. A second gear 75 is fixed to one end of each of the two first rotating rods 74. Both of the two second gears 75 are engaged with the rack two 73. A third gear 76 is fixed to the other end of each of the two first rotating rods 74. Two second rotating rods 77 are rotatably connected to one side of the T-shaped plate 71. A fourth gear 78 is fixed to one end of each of the two second rotating rods 77. Both of the two third gears 76 are engaged with the fourth gear 78. When the third gear 76 rotates, it drives the fourth gear 78 to rotate in the reverse direction. A fifth gear 79 is fixed to the other end of each of the two second 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 seam, the welding slag can be removed. Two folding rods 711 are fixed to one side of the slag removal sleeve 710. A rack three 712 is fixed to the bottom end of each of the two folding rods 711. Both of the two rack three 712 are engaged with the fifth gear 79. Connecting plates 713 are fixed to both sides of the slag removal sleeve 710. Upright rods 714 are fixed to the top of each of the two connecting plates 713. Two vertical pipes 715 are fixed to the bottom of the loading seat 53. The top ends of the two upright rods 714 extend into the interior of the vertical pipes 715, and the upright rods 714 slide in the vertical pipes 715. A limiting plate is fixed to the top end of the upright rod 714. The limiting plate slides in the vertical pipe 715. The setting of the limiting plate can prevent the upright rod 714 from sliding out of the vertical pipe 715.

[0041] Through the setting of the slag removal unit 7, during the process of the fitting plate 42 and the wing plate 43 moving away from each other, the wing plate 43 synchronously drives the slag removal sleeve 710 to move downward, so that the slag removal sleeve 710 slides over the joint of the two I-beams 3, thereby quickly removing the hot welding slag after welding, enabling defects such as pores, cracks, and incomplete penetration that may occur during the welding process to be exposed. The staff can promptly repair these defects to avoid weakening the effective load-bearing area of the weld seam due to the covering of the defects, further improving the assembly quality.

[0042] An intermittent knocking assembly 8 for intermittently knocking the I-beam 3 is provided on the second rotating rod 77. The intermittent knocking assembly 8 includes a runner 81 fixed to the second rotating rod 77. A cross plate 82 is fixed to one side of the T-shaped plate 71. A swing fork 83 is rotatably connected to the top of the cross plate 82 through a pin shaft. A triangular arc plate 84 is fixed to the runner 81. A roller 85 is rotatably connected to one end of the swing fork 83. The side surface of the roller 85 is in contact with the side surface of the triangular arc plate 84. The setting of the triangular arc plate 84 enables the runner 81 to intermittently contact the roller 85 during rotation, thereby driving the swing fork 83 to perform intermittent swinging.

[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 formed in 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 provided to drive the moving block 89 to reset. An L-shaped rod 812 is fixed on the top of the moving block 89. A connecting column 813 is rotatably connected to one side of the L-shaped rod 812. The connecting column 813 can be manually rotated. 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 immovable, so that the hammer 815 remains horizontal and does not rotate under the influence of the gravity of the hammer 815. When the hammer 815 is not in use, it is rotated to the vertical state for storage. When it is needed, it is rotated to the horizontal state. A swing rod 814 is fixed on the connecting column 813. A hammer 815 is fixed at one end of the swing rod 814. The hammer 815 can intermittently strike the I-beam 3.

[0044] Through the setting of the intermittent striking assembly 8, while the slag removal unit 7 is working, the hammer 815 can intermittently and reciprocally strike the I-beam 3. The striking can not only make the metal of the weld and its surrounding vibrate, making the slag easier to fall off from the weld, thus facilitating the subsequent slag removal mechanism to remove the slag more efficiently, but also the intermittent striking can make the weld and its nearby areas produce plastic deformation, 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 deformations in the welded parts.

[0045] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0046] During operation, place an I-beam 3 on the top of the U-shaped frame 2. Lift another I-beam 3 into the through groove 54 by means of a hoisting device. At this time, the moving door 63 is in the closed state. Start the second cylinder 55 to push the feeding seat 53 to move above the I-beam 3. Then start the motor 61. The motor 61 drives the first gear 65 to rotate. The first gear 65 drives the first rack 64 to move. The first rack 64 drives the moving door 63 to open. The upper I-beam 3 falls onto the top of the lower I-beam 3 for assembly. Start the two first cylinders 4410. The contraction of the first cylinders 4410 drives the moving plate 447 to move, thereby driving the rotating arm 444 to rotate and contract, further driving the rotating plate 443 to rotate, further driving the other moving plate 447 to move, and further causing the two fitting plates 42 and multiple wing plates 43 to contract and move. Use the fitting plates 42 and multiple wing plates 43 to fit and approach the two I-beams 3 to finely align the joints of the I-beams 3, facilitating the next welding and assembly process. After welding the joints of the two I-beams 3, start the two first cylinders 4410 to expand, thereby driving the fitting plates 42 and multiple wing plates 43 to move away from each other. Then the wing plates 43 drive the second rack 73 to move. The second rack 73 drives the second gear 75 to rotate. The second gear 75 drives the third gear 76 and the fourth gear 78 to rotate. The fourth gear 78 drives the fifth gear 79 to rotate in the reverse direction. The fifth gear 79 drives the third rack 712, the folding rod 711, and the slag-removing sleeve 710 to move downward. Then the slag-removing sleeve 710 removes the welding slag at the welding joint. When the second 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, thereby driving the swing fork 83 to intermittently swing around the pin shaft. Then the arc-shaped rack 86 drives the straight rack 810 and the moving block 89 to intermittently move. Then the swing hammer 815 intermittently reciprocates to strike the I-beam 3. After the striking, it helps to release the stress accumulated during the welding process and reduce the adverse impact of welding stress on the structural performance.
