Description

Technical Field

[0001] The invention relates to the technical field of steel structure welding, in particular to steel structure welding equipment used in building construction projects. Background Art

[0002] Steel structure is a structure made of steel materials. It is one of the main types of building structures. The structure is mainly composed of beams, steel columns, steel trusses and other components made of steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Welds, bolts or rivets are usually used to connect the components or parts. Among them, there are many types of steel, such as U-shaped steel, C-shaped steel, arc-shaped steel, and channel steel. The characteristics of steel are high strength, light weight, good overall rigidity, and strong resistance to deformation. Therefore, it is particularly suitable for building large-span, ultra-high, and ultra-heavy buildings. The material has good homogeneity and isotropy, and is an ideal elastic body, which best meets the basic assumptions of general engineering mechanics. The material has good plasticity and toughness, can have large deformation, can withstand dynamic loads well, and has a short construction period; it has a high degree of industrialization and can be produced with a high degree of mechanization. Specialized production, due to its light weight and simple construction, is widely used in large factories, venues, super high-rise buildings and other fields. Steel structures are prone to rust. Generally, steel structures need to be derusted, galvanized or painted, and maintained regularly.

Under the action of the first threaded rod 3, the movable column 2 can move along the first guide rod. The distance between the two movable columns 2 can be adjusted to adapt to cross arms of different lengths.

[0040] The support assembly also includes a support column 5, which is arranged on the top of the movable column 2 in a liftable manner. This can be achieved through a driving assembly. The driving assembly can be directly driven by an electric push rod or by a motor. A threaded rod is fixed on the output shaft of the motor to connect the threaded rod to the support column 5. The support column 5 is limited and guided to achieve up and down movement of the support column 5.

[0041] Specifically, the positioning assembly includes a support member 6 and two rotatable tilting members 7 arranged at both ends of the support member 6.

[0042] In this embodiment, the positioning assembly includes a support member 6 and two tilting members 7 arranged at both ends of the support member 6.

The tilting members 7 are arranged to be rotatable in order to enable the positioning assembly to adapt to arc steels with different curvatures. The tilting members 7 are rotated to a suitable angle and then locked to adapt to arc steels with different curvatures.

[0043] Specifically, the support member 6 is retractable, and the support member 6 includes a fixed block 601 and a movable block 602 arranged on both sides of the fixed block 601, both ends of the fixed block 601 are fixedly connected with the second threaded rod 12, the two movable blocks 602 are respectively threadedly connected to the surfaces of the two second threaded rods 12, both ends of the fixed block 601 are fixedly connected with the limit rod 13, and the limit rod 13 is movably plugged into the movable block 602; the surfaces of the two movable blocks 602 are rotatably connected with the internal threaded ring 14, the internal threaded ring 14 is threadedly connected to the second threaded rod 12, and the two movable blocks 602 are respectively rotatably connected to the two tilting members 7.

[0044] The tilting member 7 includes a connecting block 701 and an extension block 702. The connecting block 701 is movably hinged at the end of the support member 6. A third threaded rod 15 is hinged at the bottom of the connecting block 701. An internal threaded tube 16 is threadedly sleeved on the surface of the third threaded rod 15. One end of the internal threaded tube 16 is hinged to the support member 6. The tilting member 7 is telescopic, and the extension block 702 is movably connected to the connecting block 701 through a telescopic structure.

[0045] The telescopic structure includes a rectangular tube 17 and a rectangular rod 18. The rectangular tube 17 is fixedly connected to the surface of the extension block 702. A rectangular groove 19 is provided on the surface of the connecting block 701. The surface of the rectangular tube 17 is movably connected to the inner wall of the rectangular groove 19. The rectangular rod 18 is fixedly connected to the inner wall of the rectangular groove 19. The surface of the rectangular rod 18 is movably connected to the inner wall of the rectangular tube 17. The surface of the connecting block 701 is movably connected to a first cam clamp 20 through a rotating shaft. The first cam clamp 20 passes through the connecting block 701 and abuts against the surface of the rectangular tube 17. The surface of the rectangular tube 17 is movably connected to a second cam clamp 21 through a short shaft. The second cam clamp 21 can pass through the rectangular tube 17 and abut against the surface of the rectangular rod 18. The surfaces of the connecting block 701 and the extension block 702 are both rotatably connected to a baffle 22. The surface of the baffle 22 is movably connected to a roller 23. The baffle 22 is fixed to the connecting block 701 and the extension block 702 by screws.

[0046] In this embodiment, since the length and curvature of the arc-shaped steel are variable, as shown in the figure, the support member 6 and the tilting member 7 are both retractable, and the length adjustment of the positioning component and the curvature adjustment of the bending can be realized, thereby adapting to arc-shaped steels of different curvatures and lengths, as well as straight plates of different lengths.

[0047] Specifically, the perforated mounting plate 9 is rotatably connected to the support column 5, and a rotating rod 24 is fixedly connected to the surface of the perforated mounting plate 9. The rotating rod 24 is movably connected to the support column 5. A limiting groove 25 is provided on the surface of the rotating rod 24, and the inner side wall of the limiting groove 25 is movably connected to the surface of the limiting plate 26. The two sides of the limiting plate 26 are movably connected to the surface of the support column 5 through the clamping blocks 27.

[0048] In this embodiment, all-round welding between the arc steel and the cross arm can be achieved by rotation, thereby preventing the occurrence of welding corners, which may cause the weld to break easily.

[0049] Specifically, the cross arm fixing component includes a placement piece 28 and a clamping plate 29, screws 30 are provided on both sides of the placement piece 28, and the two clamping plates 29 are respectively arranged on both sides of the placement piece 28 through the screws 30, and nuts for fixing the clamping plates 29 are threadedly connected to the screws 30; the bottom of the placement piece 28 is movably connected to a connecting plate 31 through bolts, and the bottom of the connecting plate 31 is fixedly connected to an insertion rod 32, and the surface of the insertion rod 32 is movably sleeved with an insertion tube 33, and one end of the insertion tube 33 is fixedly connected to a rotating piece 34, and the rotating piece 34 is hinged to the base 1.

[0050] A support rod 35 is connected to the surface of the placement member 28 . The support rod 35 is used to overlap the top surface of the arc steel or the straight steel. A connection spring 36 is fixedly connected between the connection plate 31 and the rotating member 34 .

[0051] The surface of the placement piece 28 is movably connected with a fourth threaded rod 37, and the surface of the fourth threaded rod 37 is threadedly connected with an abutment piece 38. The surface of the placement piece 28 is also fixedly connected with a positioning rod 39, which movably passes through the abutment piece 38, and the support rod 35 is movably connected to the abutment piece 38.

[0052] In this embodiment, when it is necessary to weld cross arms at other positions of the arc steel, it is only necessary to rotate the placement piece 28. The placement piece 28 is connected to the connecting plate 31 by bolts and can be rotated so that all the support rods 35 are in contact with the top surface of the arc plate, thereby ensuring that the cross arms are vertical to the top and bottom surfaces of the arc steel and no welding offset occurs.

[0053] When the arc steel and the cross arm need to be welded and fixed, the relatively movable support assembly is first adjusted so that the distance between the screw support assemblies can adapt to the length of the cross arm. The arc steel can be positioned on the positioning assembly and the cross arm can be positioned on the cross arm fixing component by fixing them with the first mounting position on the positioning assembly and the cross arm can be positioned on the cross arm fixing component, thereby enabling the welding gun to weld the arc steel and the cross arm.

[0054] The supporting assembly includes a movable column 2, a first threaded rod 3 and a first guide column 4. The first threaded rod 3 is threadedly penetrated through the movable column 2 and is movably connected to the base 1 through a bearing. The first guide column 4 movably penetrates the movable column 2, and both ends of the first guide column 4 are fixedly connected to the surface of the base 1. When the position of the movable column 2 needs to be adjusted, the first threaded rod 3 is rotated. Under the action of the first threaded rod 3, the movable column 2 can move along the first guide rod. The distance between the two movable columns 2 can be adjusted to adapt to crossarms of different lengths.

[0055] Afterwards, the positioning assembly is installed on the support assembly through the first mounting position. The support assembly also includes a support column 5. The support column 5 can be raised and lowered and is arranged on the top of the movable column 2. This can be achieved through a driving assembly. The driving assembly can be directly driven by an electric push rod or by a motor. A threaded rod is fixed on the output shaft of the motor to connect the threaded rod to the support column 5. The support column 5 is limited and guided to achieve the up and down movement of the support column 5. A fixed position corresponding to the first mounting position is provided on the support column 5. The positioning assembly is installed through the first mounting position and the first fixed position to achieve the support of the arc steel by the positioning assembly.

[0056] like Figure 4 As shown, the positioning assembly includes a support member 6 and two tilting members 7 arranged at both ends of the support member 6. The tilting members 7 can rotate relative to the support member 6. The purpose of setting the tilting members 7 to be rotatable is to enable the positioning assembly to adapt to arc steels with different curvatures. The tilting members 7 are rotated to a suitable angle and then locked, so as to adapt to arc steels with different curvatures. Figure 6 As shown, the first mounting position is arranged on the outer side of the support member 6, and a fixing column 8 is fixedly connected at the first mounting position of the support member 6. An external thread can be opened on the fixing column 8, and the first fixing position is arranged on the inner side of the support column 5. A fixing plate with a hole is installed at the first fixing position of the support column 5. During installation, the fixing column 8 is passed through the hole reserved on the fixing plate with a hole, and then a fixing ring is threadedly connected to the fixing column 8 to realize a fixed connection between the fixing column 8 and the fixing plate with a hole, thereby realizing a fixed installation of the support member 6.

[0057] Then, the two arc-shaped steels are placed on two supporting members 6 respectively, and the arc-shaped steels are supported by the supporting members 6 and the tilting members 7. After that, the cross-arm fixing components are used to position and fix the cross-arm to facilitate welding.

[0058] Since the length and curvature of the curved steel can be changed, Figures 6 to 8 and Figures 11 to 12 As shown, the support member 6 and the tilting member 7 are both retractable, wherein the support member 6 includes a fixed block 601 and movable blocks 602 arranged on both sides of the fixed block 601, both ends of the fixed block 601 are fixedly connected to the second threaded rods 12, and the movable block 602 is threadedly connected to the surfaces of the two second threaded rods 12, as shown in FIG. Figure 8 As shown, the surface of the movable block 602 is rotatably connected with an internal threaded ring 14, and the internal threaded ring 14 is connected to the movable block 602 through a bearing and can rotate freely. The internal threaded ring 14 is threadedly connected to the second threaded rod 12. When the internal threaded tube 16 is rotated, it can move linearly on the second threaded rod 12, thereby driving the movable block 602 to move relative to the fixed block 601. During the movement, the limit rod 13 can play a guiding and limiting role to prevent deviation.

[0059] In addition, the tilting member 7 includes a connecting block 701 and an extension block 702. Figure 4 and Figure 6 As shown, the connecting block 701 is movably hinged at the end of the support member 6, and a third threaded rod 15 is hinged at the bottom of the connecting block 701. An internal threaded tube 16 is threadedly sleeved on the surface of the third threaded rod 15. One end of the internal threaded tube 16 is hinged to the support member 6. The internal threaded tube 16 can rotate around the hinge seat there around its axis, and can also rotate around the hinge axis. By rotating the internal threaded tube 16, the third threaded rod 15 can be moved relative to the internal threaded tube 16, thereby realizing the rotation of the tilting member 7 around the support member 6. The extension block 702 is movably connected to the connecting block 701 through a telescopic structure.

[0060] like Figures 11 to 12As shown, the telescopic structure includes a rectangular tube 17 and a rectangular rod 18, the rectangular tube 17 is fixedly connected to the surface of the extension block 702, a rectangular groove 19 is provided on the surface of the connecting block 701, the rectangular tube 17 can be inserted into the interior of the rectangular groove 19, the rectangular rod 18 is fixedly connected to the inner side wall of the rectangular groove 19, the rectangular rod 18 can be inserted into the interior of the rectangular tube 17, the surface of the connecting block 701 is movably connected with a first cam clamp 20 through a rotating shaft, in a locked state, the first cam clamp 20 passes through the connecting block 701 and abuts against the surface of the rectangular tube 17, the surface of the rectangular tube 17 is movably connected with a second cam clamp 21 through a short shaft, in a locked state, the second cam clamp 21 can pass through the rectangular tube 17 and abut against the surface of the rectangular rod 18, as shown in FIG. Figures 11 to 13 As shown, the first cam clamp 20 and the second cam clamp 21 have the same structure and can be locked and unlocked by rotation, thereby realizing the position adjustment of the connecting block 701 and the extension block 702. Based on the above scheme, the length adjustment of the positioning assembly and the curvature adjustment of the bending can be realized, thereby realizing adaptation to arc steels of different curvatures and lengths, as well as straight plates of different lengths.

[0061] In addition, baffles 22 are provided on the surfaces of the connecting block 701 and the extension block 702. The baffles 22 are movably connected to the connecting block 701 and the extension block 702 respectively through circular shafts. Reserved holes are opened on the baffles 22, and reserved screw holes are also provided on the surfaces of the connecting block 701 and the extension block 702. After the baffles 22 are rotated to contact the surface of the arc steel, the holes and the screw holes are connected by screws to fix the baffles 22, so that the baffles 22 can limit the arc steel. Under the extrusion of the moving column 2 and the supporting column 5, the baffles 22 can extrude the arc steel, thereby realizing the extrusion of the arc steel on the cross arm to prevent it from falling off easily.

[0062] The crossarm fixing component includes a placement piece 28 and a clamping plate 29. Screws 30 are provided on both sides of the placement piece 28. The clamping plate 29 is movably sleeved on the surface of the screw 30. After the crossarm is placed on the placement piece 28, the clamping plate 29 is moved so that the surface of the clamping plate 29 contacts the surface of the crossarm, and then fixed by a nut to achieve clamping and fixing of the crossarm. Then, the position of the moving column 2 is moved by the first threaded rod 3 to perform fine adjustments so that the surface of the arc steel contacts the end surface of the crossarm to achieve abutment to prevent false welding or excessive welds.

[0063] In addition, a connecting plate 31 is detachably installed at the bottom of the placement piece 28 by bolts, and an insertion rod 32 is fixedly connected to the bottom of the connecting plate 31. An insertion tube 33 is movably sleeved on the surface of the insertion rod 32, and one end of the insertion tube 33 is fixedly connected to the rotating piece 34 and can be rotated. By setting the insertion tube 33 and the insertion rod 32, the height of the placement piece 28 can be adjusted, so that the cross arm can be butted in height with the position to be welded to the arc steel. After the butt connection is completed, the arc steel can clamp the cross arm under the squeezing action of the two movable columns 2 and the support column 5, thereby achieving positioning and fixation, and then welding can be started to achieve fixation between the arc steel and the cross arm.

[0064] The rotating member 34 is hinged to the base 1 through a connecting shaft, so the rotating member 34 can rotate. The rotating member 34 is set to rotate in order to realize the positioning of the cross arm at different positions of the arc steel. A connecting spring 36 is arranged between the connecting plate 31 and the rotating member 34. When the connecting plate 31 moves upward, the connecting spring 36 is stretched, and the surface of the placing member 28 is movably connected to the fourth threaded rod 37, and the surface of the fourth threaded rod 37 is threadedly connected to the abutment 38. The surface of the placing member 28 is also fixedly connected to a positioning rod 39, and the positioning rod 39 movably penetrates the abutment 38. The support rod 35 is movably connected to the abutment 38. When positioning the cross arm, the support member 6 is first moved upward, such as Figure 1 As shown, the support rod 35 passes through the abutment 38 and contacts the top surface of the positioned arc steel, so that the placement piece 28 can be positioned. Under the action of the connecting spring 36 and the support rod 35, the cross arm can be easily docked with the arc steel. Then, the fourth threaded rod 37 is rotated to make the abutment 38 move toward the direction close to the arc steel and abut against the surface of the arc steel. There is space between the abutment position of the abutment 38 and the welding position of the cross arm and the arc steel, and welding is not hindered.

[0065] Based on the above scheme, when it is necessary to weld crossarms at other positions of the arc steel, it is only necessary to rotate the placement piece 28. The placement piece 28 and the connecting plate 31 are connected by bolts and can be rotated so that all the support rods 35 are in contact with the top surface of the arc plate, which can ensure that the crossarm is in a vertical state with the top and bottom surfaces of the arc steel, and no welding offset will occur.

[0066] In the above technical solution, it is convenient to weld the three locations where the arc steel and the cross arm are connected, but it is difficult to weld the bottom, so it is necessary to flip the arc steel and the cross arm after the three locations have been welded.

[0067] First, remove the bolts between the placement member 28 and the connecting plate 31 to separate the placement member 28 from the connecting plate 31. Figures 3 to 5As shown, in the present embodiment, the fixed plate with holes can be rotated, and a rotating rod 24 is fixedly connected to the surface of the driving fixed plate, and the rotating rod 24 is movably connected to the supporting column 5, and a limiting groove 25 is provided on the surface of the rotating rod 24. When rotation is required, the limiting plate 26 inserted in the limiting groove 25 is pulled out, and the rotating rod 24 is rotated, so that the rotating rod 24 drives the fixed plate with holes to rotate, thereby realizing the rotation of the supporting member 6, and then realizing the rotation of the arc steel and the cross arm. After rotating to a suitable angle, the limiting plate 26 is inserted into the inside of the limiting groove 25 to limit the rotating rod 24. The two sides of the limiting plate 26 are fixedly connected with a clamping block 27, which can fit with the two side surfaces of the supporting column 5, so as to realize the limiting of the limiting plate 26, and then prevent the supporting member 6 from rotating, and finally welding can be performed.

[0068] The support member 6 is also provided with a second mounting position, on which a connecting column 10 identical to the fixing column is provided. The support column 5 is provided with a second fixing position, and the second fixing position is fixedly connected to the fixing column 10. Figures 1 to 3 The perforated support shell 11 shown is installed by docking the connecting column 10 with the opening on the perforated support shell 11, and can be fixed by a fixing ring. Based on the above scheme, the positioning assembly includes a support member 6 and a tilting member 7. At this time, the tilting member 7 is located above the support member 6. The internal threaded tube 16 is rotated to keep the tilting member 7 and the support member 6 perpendicular to each other. By adjusting the distance between the movable block 602 and the fixed block 601, the two tilting members 7 can be moved closer to or farther away from each other, so that round tube steels of different diameters can be clamped to achieve welding between two round tube steels. In addition, by adjusting the distance between the extension block 702 and the connecting block 701, round tube steels of different diameters can be better adapted. In addition, the support of the round tube steel can be achieved by the cross arm fixing component, and welding between three round tubes can be achieved to a certain extent. Further, the above-mentioned screw holes are as follows Figures 11 to 12 As shown, the baffle 22 is rotated to drive the roller 23 thereon to rotate, and then the baffle 22 is fixed by screws. The roller 23 can be used to contact the round tube, so that the round tube can be rotated after being fixed, which is convenient for circumferential welding.
