[0002] Building construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a selected location. During the building construction process, steel structures often need to be welded, which requires the use of steel structure welding equipment.

[0003] A steel structure welding device for building construction, with announcement number CN114952141B, includes a supporting base plate, a supporting top plate on one side of the supporting base plate, and supporting side plates at both ends of the supporting base plate for fixing the supporting top plate.

[0007] According to the above technical solution, the mounting base and the L-shaped mounting bracket are fixedly connected, and the telescopic rod and the telescopic shell are slidably connected.

[0008] According to the above technical solution, a tooth is provided on the right side of the movable plate, and the tooth meshes with the hollow gear. A second tooth is provided inside the hollow gear.

[0009] According to the above technical solution, the bottom of the piston housing is provided with an opening, and the second connecting rod is located at the bottom of the left side of the connecting plate.

[0010] According to the above technical solution, the left side of the L-shaped moving rod is equipped with a protective device for protecting the weld.

[0011] According to the above technical solution, the protective device includes an L-shaped movable rod fixedly installed on the left side of the L-shaped movable rod and an installation rod fixedly installed on the left side of the L-shaped mounting bracket. A top rod is fixedly installed at the bottom of the L-shaped movable rod. A spring three is fixedly installed on the right side of the installation rod. A triangular movable plate is fixedly installed at the end of the spring three away from the installation rod. An L-shaped connecting rod is fixedly installed at the bottom of the triangular movable plate. A pad one is fixedly connected to the right side of the L-shaped connecting rod.

A rotating rod is rotatably installed on the right side of the installation block. A rotating gear is assembled on the left side of the rotating rod, and a rolling wheel is assembled on the right side of the rotating rod.

[0012] According to the above technical solution, the rolling wheel and the top of the support base are in rolling engagement, and the rotating gear and the rack mesh with each other.

[0013] According to the above technical solution, the top of the connecting plate is equipped with an absorption device for absorbing impurities after grinding at the weld.

[0014] According to the above technical solution, the absorption device includes a mounting plate 1 fixedly installed on the right side of the connecting plate, an absorption fan set on the top of the connecting plate, a connecting pipe 1 connected to the left side of the absorption fan, a collection chamber connected to the end of the connecting pipe 1 away from the absorption fan, a connecting pipe 2 connected to the output end of the absorption fan, an absorption frame fixedly connected to the end of the connecting pipe 2 away from the absorption fan, a mounting plate 2 fixedly installed on the right side of the mounting plate 1, a rotating shaft 1 rotatably connected through and to the right side of the mounting plate 2, a friction wheel mounted on the right side of the rotating shaft 1, a transmission gear 1 mounted on the left side of the rotating shaft 1, a rotating shaft 2 rotatably installed on the right side of the mounting plate 2, a transmission gear 2 mounted on the right side of the rotating shaft 2, and a grinding wheel mounted on the left side of the rotating shaft 2.

[0015] According to the above technical solution, the grinding wheel is disposed inside the absorption frame, and the first transmission gear and the second transmission gear mesh with each other.

[0016] The advantages of this application are: (1) This application sets up a flipping device, which uses the connecting plate to drive the connecting rod 2 and the L-shaped moving rod to move downward when the connecting plate is pressed down, so that the piston block exhausts gas downward in the piston shell. After welding is completed, the spring 1 releases elastic potential energy to drive the movable plate to move upward. Through the tooth meshing transmission between the movable plate and the hollow gear, as well as the action of the piston rod, piston block and piston shell, the rotating rod and clamping frame are driven to rotate slowly, so as to realize the automatic flipping of the workpiece without manual intervention, avoiding damage to the welded parts caused by manual flipping, and greatly improving welding efficiency and safety.

[0017] (2) By setting up a protective device, when the L-shaped moving rod moves the L-shaped movable rod, the top rod pushes the triangular moving plate to squeeze the inclined surface. The triangular moving plate moves and then drives the rotating gear to drive the rolling wheel to roll and cooperate with the support base, so that the first pad and the second pad are tightly attached to the bottom of the weld. This effectively prevents the welded workpiece from being penetrated by the molten pool under the action of the high temperature molten pool, avoids the formation of back "weld bead" or direct "burn-through", and ensures the internal quality and appearance of the weld.

[0018] (3) By setting up an absorption device and a grinding wheel, when the welding equipment is moving, the friction wheel and the support base rub against each other and drive the transmission gear one and transmission gear two to rotate, driving the grinding wheel to grind the weld in real time. At the same time, the absorption fan promptly pumps the metal dust and impurities generated by grinding to the collection bin for centralized collection through the connecting pipe one, connecting pipe two and absorption frame, effectively preventing dust from entering the air and polluting the environment, protecting the health of the operators, ensuring the cleanliness of the work area, and improving the efficiency of subsequent processes.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0022] Example 1, as Figures 1-6As shown, an automatic steel structure welding device for building construction includes a support base 100, a support side plate 200 fixedly installed on the top of the support base 100, and a support top plate 300 fixedly installed on the top of the support side plate 200, thus forming a stable top frame. An electric push rod 400 is provided at the bottom of the support top plate 300, an electric push rod 500 is assembled at the middle of the output end of the electric push rod 400, a connecting plate 600 is fixedly installed at the output end of the electric push rod 500, a welding head 700 is provided at the bottom of the connecting plate 600, a clamping mounting plate 800 is fixedly installed on the top of the support base 100, and a flipping device 900 is assembled on the top of the support base 100. The flipping device 900 includes a rotating mounting plate... The rotating rod 916 on the left side of the clamping mounting plate 800, the hollow gear 910 rotatably mounted on the right side of the clamping mounting plate 800, and the L-shaped mounting bracket 901 fixedly mounted on the top left side of the support base 100 provide support and guidance. A clamping bracket 917 is fitted in the middle of the rotating rod 916. An electric push rod 918 is installed at the top of the clamping bracket 917, which can firmly and stably clamp steel structure workpieces of different sizes. A clamping block 919 is fixedly mounted at the bottom of the clamping bracket 917. A telescopic shell 907 is fitted on the outer side of the rotating rod 916. A spring 902 is fixedly mounted at the bottom of the L-shaped mounting bracket 901. A connecting rod 903 is fixedly mounted at the end of the spring 902 away from the L-shaped mounting bracket 901. The right end of the connecting rod 903... A second connecting rod 904 is fixedly installed on the side, located at the bottom left side of the connecting plate 600. An L-shaped moving rod 905 is fixedly installed at the bottom of the first connecting rod 903. A movable plate 906 is fixedly installed on the right side of the L-shaped moving rod 905. A tooth 1 is provided on the right side of the movable plate 906, meshing with a hollow gear 910. A second tooth 2 is provided inside the hollow gear 910. A second spring 908 is fixedly installed on the top of the inner wall of the telescopic shell 907. A telescopic rod 909 is fixedly installed at the end of the second spring 908 away from the telescopic shell 907. The telescopic rod 909 is slidably connected to the telescopic shell 907. Under the action of the second spring 908, the telescopic rod 909 contacts the second tooth 2 inside the hollow gear 910. When the hollow gear 910 rotates clockwise, the second tooth contacts the telescopic rod 909, causing the rotating rod 916 to rotate. When the hollow gear 910 rotates counterclockwise, the telescopic rod 909 retracts under the action of the second tooth, preventing it from rotating the rotating rod 916. A piston rod 913 is fixedly installed at the bottom of the L-shaped moving rod 905. A piston block 914 is fixedly installed at the bottom of the piston rod 913. A piston housing 912 is slidably connected to the outer side of the bottom of the piston rod 913. An opening is provided at the bottom of the piston housing 912. An installation base 911 is fixedly installed at the bottom of the piston housing 912. The installation base 911 is fixedly connected to the L-shaped mounting bracket 901. A one-way valve 915 is provided on the right side of the piston housing 912 to control the unidirectional flow of gas.This application utilizes a flipping device 900. When the connecting plate 600 is pressed down, it drives the connecting rod 904 and the L-shaped moving rod 905 to move downward, causing the piston block 914 to exhaust air downward within the piston shell 912. After welding is completed, the spring 902 releases its elastic potential energy, causing the movable plate 906 to move upward. Through the meshing transmission between the movable plate 906 and the hollow gear 910, and the action of the piston rod 913, piston block 914, and piston shell 912, the rotating rod 916 and the clamping frame 917 are driven to rotate slowly, achieving automatic flipping of the workpiece without manual intervention. This avoids damage to the welded parts caused by manual flipping and significantly improves welding efficiency and safety.

[0023] In practical use, the steel structure workpiece to be welded is placed on the clamping frame 917 on the support base 100, positioning the workpiece between the electric push rod 918 and the clamping block 919. The output end of the electric push rod 918 extends to clamp and fix the steel structure workpiece, ensuring that the workpiece will not loosen or shift during subsequent welding and flipping. After the workpiece is clamped and fixed, the electric push rod 400 is activated, and its output end extends, causing the electric push rod 500 to move. The movement of the electric push rod 500 drives the connecting plate 600 and the welding head 700 to move. When the welding head 700 moves to the appropriate position for welding the workpiece, the electric push rod 500 is activated, its output end extends, and pushes the connecting plate 600 downward. The welding head 700 descends synchronously with the connecting plate 600 until it reaches a welding position close to the workpiece surface. The distance between the welding nozzle of the welding head 700 and the weld seam on the workpiece reaches the preset welding distance. The welding head 700 then initiates welding operations on the front weld seam of the workpiece. During the descent of the connecting plate 600, it contacts the connecting rod 904. The descent of the connecting rod 904 causes the connecting rod 903 to move downwards. The downward movement of the connecting rod 903 causes the L-shaped moving rod 905 to move downwards simultaneously. The spring 902 is stretched, and the downward movement of the L-shaped moving rod 905 causes the piston rod 913 to move downwards. The downward movement of the piston rod 913 causes the piston block 914 to slide downwards within the piston housing 912. During downward movement, the gas inside the piston housing 912 is discharged through the one-way valve 915. Simultaneously, the L-shaped moving rod 905 moves downward, causing the movable plate 906 to move downward. The movable plate 906's downward movement drives the hollow gear 910 to rotate. The internal teeth of the hollow gear 910 rotate, preventing them from engaging with the telescopic rod 909. After welding, the output end of the electric push rod 500 moves upward, causing the connecting plate 600 to move upward. The connecting plate 600 no longer compresses the connecting rod 904, and the spring 902 releases its elastic potential energy, pulling the connecting rod 903 upward. The upward movement of the connecting rod 903 drives the L-shaped moving rod 905 upward. The L-shaped moving rod 905 moves upward... The upward movement of rod 905 causes piston rod 913 and piston block 914 to move upward. Piston rod 913 then moves piston block 914 upward within piston housing 912. As piston block 914 moves upward, a negative pressure is created within piston housing 912, drawing in external air through the bottom opening. This causes piston rod 913 and piston block 914 to slowly move upward. Simultaneously, the upward movement of L-shaped moving rod 905 causes movable plate 906 to slowly move upward. Movable plate 906 then rotates hollow gear 910. When hollow gear 910 rotates, its teeth engage with telescopic rod 909, causing rotating rod 916 to rotate. Rotating rod 916 slowly rotates, flipping the clamped workpiece. Then, electric push rod 400 and welding head 700 are activated again.Welding is performed on the exposed weld seams after the workpiece is flipped. After all welding is completed, electric push rod 2 (500) retracts, causing welding head 700 to rise and reset. Electric push rod 3 (918) releases its grip on the workpiece, allowing the operator to remove the welded workpiece from the device. This process enables welding and flipping of steel structure workpieces, significantly improving welding efficiency and quality while avoiding potential damage to welded areas caused by manual flipping.

[0024] Example 2, as Figures 7-9 As shown, based on Embodiment 1, a protective device 1000 for protecting the weld is assembled on the left side of the L-shaped movable rod 905. The protective device 1000 includes an L-shaped movable rod 1001 fixedly installed on the left side of the L-shaped movable rod 905 and a mounting rod 1003 fixedly installed on the left side of the L-shaped mounting bracket 901. A top rod 1002 is fixedly installed at the bottom of the L-shaped movable rod 1001. A spring 1004 is fixedly installed on the right side of the mounting rod 1003. A triangular movable plate 1005 is fixedly installed at the end of the spring 1004 away from the mounting rod 1003. The triangular movable plate 1005 can have a reset capability under the action of the spring 1004. The top rod 1002 will move accordingly and push the inclined surface of the triangular movable plate 1005, forcing the triangular movable plate... 1005 generates horizontal displacement. An L-shaped connecting rod 1006 is fixedly installed at the bottom of the triangular moving plate 1005. A pad 1007 is fixedly connected to the right side of the L-shaped connecting rod 1006. A pad 2 1008 is slidably installed on the top of the pad 1007. A rack 1009 is fixedly installed on the right side of the pad 2 1008. An mounting block 1010 is fixedly connected to the right side of the pad 1007. A rotating rod 1012 is rotatably installed on the right side of the mounting block 1010. A rotating gear 1011 is assembled on the left side of the rotating rod 1012. The rotating gear 1011 meshes with the rack 1009. A rolling wheel 1013 is assembled on the right side of the rotating rod 1012. The rolling wheel 1013 is in rolling engagement with the top of the support base 100 and can roll smoothly on the support base 100. This application, by setting up a protective device 1000, when the L-shaped moving rod 905 drives the L-shaped movable rod 1001 to move, the top rod 1002 pushes the triangular moving plate 1005 to squeeze the inclined surface. The movement of the triangular moving plate 1005 then drives the rotating gear 1011 to drive the rolling wheel 1013 to roll and cooperate with the support base 100, so that the pad 1007 and the pad 2 1008 are tightly attached to the bottom of the weld, effectively preventing the welded workpiece from being penetrated by the molten pool under the action of the high temperature molten pool, avoiding the formation of back "weld beads" or direct "burn-through", and ensuring the internal quality and appearance of the weld.

[0025] In practical use, when the L-shaped moving rod 905 moves downward, it drives the L-shaped movable rod 1001 downward. The downward movement of the L-shaped movable rod 1001 drives the top rod 1002 downward. As the top rod 1002 moves downward, its end gradually contacts and presses against the inclined surface of the triangular moving plate 1005. As the top rod 1002 continues to move downward, the pressing force of the top rod 1002 on the inclined surface of the triangular moving plate 1005 gradually increases, pushing the triangular moving plate 1005 to overcome the elastic force of the spring 1004 and move to the left. The spring 1004 is compressed, storing elastic potential energy. When the movable plate 1005 moves to the left, it drives the L-shaped connecting rod 1006 to move. The movement of the L-shaped connecting rod 1006 drives the pad 1007 to move. When the pad 1007 moves, it drives the rolling wheel 1013 to contact the top of the support base 100, causing the rolling wheel 1013 to rotate. The rotation of the rolling wheel 1013 drives the rotating rod 1012 to rotate. The rotation of the rotating rod 1012 drives the rotating gear 1011 to rotate. The rotation of the rotating gear 1011 drives the rack 1009 to move. The movement of the rack 1009 drives the pad 2 1008 to move, placing the pad 1007 and the pad 2 1008 on the ground. Placed under the weld seam of the workpiece to be welded, after welding is completed, the L-shaped moving rod 905 moves upward, causing the L-shaped movable rod 1001 to move upward. The L-shaped movable rod 1001 moves upward, causing the top rod 1002 to move upward. The top rod 1002 gradually disengages from the inclined surface of the triangular moving plate 1005. The spring 1004 releases its elastic potential energy, pushing the triangular moving plate 1005 to move to the right. When the triangular moving plate 1005 moves to the right, it causes the L-shaped connecting rod 1006 to move. The movement of the L-shaped connecting rod 1006 causes the pad 1007 to move. When the pad 1007 moves, it causes the rolling wheel 1 to move. 013 contacts the top of the support base 100, and the rolling wheel 1013 rotates. The rolling wheel 1013 drives the rotating rod 1012 to rotate. The rotating rod 1012 drives the rotating gear 1011 to rotate. The rotating gear 1011 drives the rack 1009 to move. The movement of the rack 1009 drives the pad 1008 to move and return to its original position, preparing for the next welding machine. The workpiece is suspended below, which avoids the workpiece from being exposed to the high temperature molten pool under the action of gravity and arc blowing force, resulting in the formation of back weld beads or direct burn-through, which seriously affects the internal quality and appearance of the weld.

[0026] Example 3, as Figures 10-11As shown, based on Embodiment 1, the top of the connecting plate 600 is equipped with an absorption device 1100 for absorbing impurities after grinding at the weld. The absorption device 1100 includes a mounting plate 1106 fixedly installed on the right side of the connecting plate 600, an absorption fan 1101 installed on the top of the connecting plate 600, a connecting pipe 1102 connected to the left side of the absorption fan 1101, and a collection chamber 1103 connected to the end of the connecting pipe 1102 away from the absorption fan 1101, thereby constituting the extraction and collection of impurities. The collection channel and the output end of the absorption fan 1101 are connected to a connecting pipe 2 1104. An absorption frame 1105 is fixedly connected to the end of the connecting pipe 2 1104 away from the absorption fan 1101. Impurities are absorbed through the absorption frame 1105 and collected in the collection chamber 1103. A mounting plate 2 1107 is fixedly installed on the right side of mounting plate 1 1106. A rotating shaft 1108 is rotatably connected through the right side of mounting plate 2 1107. A friction wheel 1109 is mounted on the right side of the rotating shaft 1108. When the entire welding... When the connecting equipment moves along the weld seam direction, the friction wheel 1109 rolls accordingly, thereby driving the rotating shaft 1108 to rotate. A transmission gear 1110 is mounted on the left side of the rotating shaft 1108, and a rotating shaft 1112 is rotatably mounted on the right side of the mounting plate 1107. A transmission gear 1111 is mounted on the right side of the rotating shaft 1112. The transmission gears 1110 and 1111 mesh with each other. When the friction wheel 1109 drives the rotating shaft 1108 and the transmission gear 1110 to rotate, power is transmitted through… The meshing gears transmit power to the transmission gear 1111. The left side of the rotating shaft 1112 is equipped with a grinding wheel 1113. The grinding wheel 1113 is located inside the absorption frame 1105, ensuring that while the grinding wheel 1113 is grinding the weld in real time, the metal dust, debris and other impurities it generates can be completely covered by the absorption frame 1105 and immediately drawn away by the negative pressure airflow generated by the absorption fan 1101 through the connecting pipe 1104 and transported to the collection chamber 1103 through the connecting pipe 1102. This application, by setting up an absorption device 1100 and a grinding wheel 1113, allows the friction wheel 1109 to rotate with the support base 100 during welding operations, driving the transmission gear 1110 and transmission gear 2 1111 to operate. This drives the grinding wheel 1113 to perform real-time grinding of the weld. At the same time, the absorption fan 1101, through connecting pipe 1102, connecting pipe 2 1104, and absorption frame 1105, promptly pumps the metal dust and impurities generated during grinding to the collection chamber 1103 for centralized collection. This effectively prevents dust from entering the air and polluting the environment, protects the health of operators, ensures the cleanliness of the work area, and improves the efficiency of subsequent processes.

[0027] In practical use, after welding is completed, the electric push rod 400 continues to operate, driving the electric push rod 500 to move. The movement of the electric push rod 500 causes the connecting plate 600 to move to the right. The mounting plate 1106, fixedly installed on the right side of the connecting plate 600, moves to the right accordingly. The mounting plate 1106 then drives the mounting plate 1107 to move to the right. The rotating shafts 1108 and 1112, rotatably mounted on the mounting plate 1107, also move to the right. During this rightward movement, the friction wheel 1109 mounted on the right side of the rotating shaft 1108... In the process, the friction wheel 1109 rotates due to rolling friction with the top surface of the support base 100. The rotation of the friction wheel 1109 drives the first rotating shaft 1108 to rotate, which in turn drives the first transmission gear 1110. The rotation of the first transmission gear 1110 drives the second transmission gear 1111 to rotate in the opposite direction. The rotation of the second transmission gear 1111 drives the second rotating shaft 1112 to rotate, which in turn drives the grinding wheel 1113 to rotate. The rotating grinding wheel 1113 cleans the weld excess and slag on the surface of the workpiece after welding. Grinding is performed to make the weld surface smooth and eliminate stress concentration and surface defects at the weld. While the grinding wheel 1113 grinds the weld, the absorption fan 1101 is started. After the absorption fan 1101 starts working, it generates negative pressure suction, which is connected to the absorption frame 1105 through the connecting pipe 1104. The absorption frame 1105 is located around the grinding wheel 1113, surrounding it and able to suck in the metal dust and impurity particles generated during the grinding process. The gas containing dust is then... The absorption frame 1105 enters the connecting pipe 2 1104, and then enters the absorption fan 1101 through the connecting pipe 2 1104. Finally, the absorption fan 1101 sends the gas to the collection chamber 1103 through the connecting pipe 1 1102. The collection chamber 1103 centrally collects and settles the incoming dust-laden gas. The dust gradually settles and accumulates in the collection chamber 1103, thus preventing dust from entering the air, effectively avoiding environmental pollution, protecting the health of operators, ensuring the cleanliness of the work area, and improving the efficiency of subsequent processes.
