Description

Technical Field

[0001] This invention relates to the field of steel structure column welding technology, and in particular to a welding equipment for processing steel structure columns. Background Technology

[0002] Steel structure buildings are structures constructed using structural steel to form a load-bearing structure. They typically consist of beams, columns, trusses, and other load-bearing components made of shaped steel, steel plates, and steel pipes. These, along with the roof, floors, and walls, together form the building's structural envelope. The components are usually connected by welds, bolts, or rivets. Due to their light weight and ease of construction, they are widely used in large factories, stadiums, and high-rise buildings. Steel structure columns are a type of steel structure component, and welding equipment is required for their welded connections.

[0003] A search revealed that existing technology CN118455915B discloses a welding equipment for processing steel structure columns. Addressing the issues of low automation, large size requiring manual loading and unloading, cumbersome operation, and inconvenience for rotary welding, the following solution is proposed: a base; a support column rotatably mounted on top of the base; a placement plate movably connected to the top of the support column; four symmetrically arranged wedge-shaped blocks fixedly mounted on the top of the placement plate; and multiple I-beam support frames fixedly mounted on the top of the base. This facilitates automatic loading and unloading of steel structures, automatic clamping and fixing of the steel structures, and welding operations at different angles and positions, making it user-friendly. However, the following problems remain: The robotic arm rotates to drive the steel structure to complete welding work at different angles and positions. However, when welding different shapes, such as H-beams, the robotic arm needs to frequently adjust its position to make it contact the welding position while the steel structure is rotating, which is inconvenient.

[0004] To address the aforementioned issues, we propose a welding device for processing steel structure columns. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing a welding device for processing steel structure columns.

[0007] In the above-mentioned welding equipment for processing steel structure columns, a column three is also fixed to the outer wall of the end of the splicing guide rail two. The end of the column three is provided with a fixing port. A groove is provided on the upper surface of the support base. An electric push rod is fixed in the groove. A clamping rod matching the fixing port is fixed to the driving end of the electric push rod.

[0008] In the above-mentioned welding equipment for processing steel structure columns, the bearing and fixing mechanism includes a sliding groove opened on the support base, a bearing plate slidably arranged in the sliding groove, bearing grooves of different shapes opened on the bearing plate, a sliding plate fixed on the outer wall of the bearing plate, an adjustment groove opened at the connection between the support base and the sliding plate, a serration evenly arranged in the transverse direction on the upper side wall of the sliding plate, a motor fixed on the support base, and a gear meshing with the serration fixed on the drive end of the motor; Hydraulic cylinders are fixedly installed at the upper ends of the two columns, and the driving ends of the two hydraulic cylinders are fixedly connected to a fixing plate. Two clamps are fixedly installed on the lower side wall of the fixing plate.

[0009] In the above-mentioned welding equipment for processing steel structure columns, a vertical plate is fixedly connected to the upper side wall of the slider one, and an air suction hood facing the welding gun is fixed to the upper end of the vertical plate. A cooling tank is fixed to the outer wall of the vertical plate, and a heat-conducting plate and a filter element tank are fixedly inserted on the cooling tank. An air suction pump is connected to one end of the filter element tank located outside the cooling tank. A cavity is opened in the heat-conducting plate. A water storage tank is also fixed to the outer wall of the vertical plate. A drain outlet is opened on the lower side wall of the water storage tank. A valve is installed on the drain outlet. A heat-conducting groove is opened on the upper side wall of the heat-conducting plate. A collection tank is fixed to the end of the heat-conducting plate. A drain outlet communicating with the collection tank is opened on the bottom wall of the heat-conducting groove. An airflow pipe is connected between the air suction hood and the heat-conducting plate. An exhaust port is opened on the lower side wall of the heat-conducting plate.

[0010] In the above-mentioned welding equipment for processing steel structure columns, a piston plate is slidably arranged inside the collection tank, a connecting rod is fixedly connected to the lower side wall of the piston plate, a filter screen is fixed to the end of the filter element tank, one end of the connecting rod extends through the lower side wall of the cooling tank into its interior and is fixedly connected to a scraper that contacts the outer wall of the filter screen, and a telescopic spring is sleeved on the outer wall of the end of the connecting rod, and the two ends of the telescopic spring are fixedly connected to the lower end of the collection tank and the outer wall of the connecting rod, respectively.

[0011] In the welding equipment for processing steel structure columns described above, the bottom wall of the heat conduction tank is provided with a flow guiding slope, and the lowest end of the flow guiding slope is located on one side of the collection tank.

[0012] Compared with existing technologies, the advantages of the welding equipment used for processing steel structure columns are: 1. An openable annular guide rail is provided. When the annular guide rail is open, it is convenient to place the steel structure workpiece to be welded into the annular guide rail, and the clamps can lift and press down to clamp and fix the upper and lower steel structure workpieces. After the steel structure workpiece is fixed, the motor drives the splicing guide rail two to rotate and connect with the splicing guide rail one to form a complete annular guide rail, allowing the welding torch to move in a circle. For irregular columns such as H-beams, the welding surface can be switched by rotating 90°. The linear guide rail drives the welding torch to move in a straight line, avoiding frequent adjustment of the welding torch position and significantly improving welding efficiency. 2. The bearing plate is equipped with bearing grooves of various cross sections (suitable for round, H-beam steel, etc.). The workpiece is accurately translated by the motor driving the gear to rotate and meshing with the saw teeth, and automatically aligns with the center of the circular guide rail. 3. During the welding process, the fumes enter the heat-conducting plate cavity through the suction hood and airflow pipe. Cooling water flows out continuously along the guide slope to absorb the heat of the heat-conducting plate, achieving rapid cooling of the heat-conducting plate and fumes. The filtered low-temperature fumes are purified a second time through the filter cartridge canister to avoid high-temperature damage to the filter cartridge. After absorbing heat, the cooling water is collected in the collection tank, pushing the piston plate down. The connecting rod drives the scraper to remove impurities from the filter screen, realizing continuous automatic operation of fume cooling and filter screen cleaning. In summary, this invention, by setting up annular and linear guide rails, is suitable for welding steel structure workpieces of different shapes, avoiding frequent adjustments to the welding torch position and significantly improving welding efficiency. During the welding process, the fumes are discharged, cooled, and filtered for purification, thus completing the fume treatment and preventing high-temperature damage to the filter element.

Detailed Implementation

[0015] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0016] Reference Figures 1-7A welding device for processing steel structure columns includes a support base 1, an annular guide rail on the upper side of the support base 1, a slider 23 slidably disposed within the annular guide rail, the annular guide rail being divided into a splicing guide rail 3 and a splicing guide rail 2 5, a column 3 6 fixed to the outer wall of the end of the splicing guide rail 2 5, a fixing port 9 opened at the end of the column 3 6, a groove opened on the upper surface of the support base 1, an electric push rod 7 fixed within the groove, a clamping rod 8 matching the fixing port 9 fixed to the driving end of the electric push rod 7, initially, the splicing guide rail 2 5 and the splicing guide rail 3 are separated, the upper steel structure to be welded is placed into the corresponding shaped bearing groove, the motor 12 is started to drive the gear 13 to rotate, the gear 13 meshing with the saw teeth to drive the sliding plate. 14 and the bearing plate 11 move to make the center of the steel structure coincide with the center of the annular guide rail. The hydraulic cylinder 16 drives the clamp 18 to move down and contact the edge of the steel structure. The clamp completes the clamping of the steel structure. Then, the hydraulic cylinder 16 is started to move the steel structure up. The motor 12 drives the bearing plate 11 to move outward and put the lower steel structure to be welded into the corresponding bearing groove. Then, the bearing plate 11 is moved inward until the center of the steel structure coincides with the center of the annular guide rail 3. This ensures that the centers of the upper and lower steel structures are consistent and coincident. The drive end of the hydraulic cylinder 16 retracts and moves the upper steel structure down to contact and align with the lower steel structure, avoiding welding deviation. The clamp 18 presses the workpiece and the bearing groove limits the bearing, ensuring the stability of the workpiece to be welded. After the upper and lower steel structures are connected, the motor 4 is started to drive the column 3 6 and the splicing guide rail 2 5 to rotate until the splicing guide rail 2 5 and the splicing guide rail 1 3 are connected to form a complete ring guide rail. The electric push rod 7 is started to make the clamping rod 8 lock into the fixing port 9, which completes the limit of the column 3 6, prevents the column 3 6 from shaking, and ensures the stability of the ring guide rail after splicing.

[0017] The support base 1 is fixed with two columns 1 2. A splicing guide rail 1 3 is fixed between the two columns 1 2. A motor 4 is fixed on the support base 1. A second column is fixed to the drive end of the motor 4. A second splicing guide rail 2 5 is fixed to the outer wall of the second column. The splicing of the first and second splicing guide rails 1 3 and 2 5 is completed by the rotation of the second column. A linear guide rail 20 is fixed on a slider 2 23. A slider 1 21 is slidably mounted on the linear guide rail 20. A robotic arm is fixed on the slider 1 21. A welding torch 19 is fixed to the end of the robotic arm. When performing... When welding circular steel pipes, the robotic arm adjusts the welding torch 19 to contact the connection point of the steel structure, and the slider 23 drives the linear guide rail and the welding torch 19 to make circular motion, so that the welding torch 19 completes the welding at the joint. When welding rectangular steel structures such as H-beams, the robotic arm drives the welding torch to contact the joint, and the slider 21 moves along the linear guide rail to complete the welding work on one side. When welding the other side, the annular guide rail drives the linear guide rail and the welding torch to rotate 90°, so that the welding work at the joint on the other side can be carried out. In summary, by setting up annular and linear guide rails 20 to drive the welding torch 19 to make circular and linear movements, the welding work at the joint of circular steel pipes and H-beams can be completed. Furthermore, the sliders 21 and 23 on the annular and linear guide rails 20 can be moved by using servo motors combined with pinions, and by setting gear rings and gear plates on the annular and linear guide rails 20 to mesh with the pinions. Alternatively, they can be moved by using common methods such as driving a drive motor to rotate a roller along its guide rail. The method of sliders 21 and 23 moving on the guide rail is more common and will not be elaborated here.

[0018] The support base 1 is also provided with a bearing fixing mechanism for supporting and fixing the steel structure. The bearing fixing mechanism includes a slide groove 10 opened on the support base 1, a bearing plate 11 slidably arranged in the slide groove 10, bearing grooves of different shapes opened on the bearing plate 11, a sliding plate 14 fixed on the outer wall of the bearing plate 11, an adjustment groove 15 opened at the connection between the support base 1 and the sliding plate 14, and a serration evenly arranged in the transverse direction on the upper side wall of the sliding plate 14. A motor 12 is fixed on the support base 1, and a gear 13 that meshes with the serration is fixed at the drive end of the motor 12. Hydraulic cylinders 16 are fixedly installed on the upper ends of the two columns 12. The driving ends of the two hydraulic cylinders 16 are fixedly connected to a fixing plate 17. Two clamps 18 are fixedly installed on the lower side wall of the fixing plate 17.

[0019] A vertical plate 22 is fixedly connected to the upper side wall of slider 21. An air suction hood 26 facing the welding torch 19 is fixed to the upper end of the vertical plate 22. A cooling tank 24 is fixed to the outer wall of the vertical plate 22. A heat-conducting plate 28 and a filter cartridge 27 are fixedly inserted into the cooling tank 24. An air suction pump is connected to one end of the filter cartridge 27 located outside the cooling tank 24. A cavity is formed inside the heat-conducting plate 28. A water storage tank 29 is also fixed to the outer wall of the vertical plate 22. A drain outlet with a valve is formed on the lower side wall of the water storage tank 29. A heat-conducting groove is formed on the upper side wall of the heat-conducting plate 28. A collection tank 30 is fixed to the end of the heat-conducting plate 28. A flow-guiding slope is formed on the bottom wall of the heat-conducting groove, with the lowest point of the flow-guiding slope located on one side of the collection tank 30. A drain outlet communicating with the collection tank 30 is formed on the bottom wall of the heat-conducting groove. An airflow is connected between the air suction hood 26 and the heat-conducting plate 28. The lower side wall of the tube 25 and the heat-conducting plate 28 is provided with an exhaust port. A piston plate is slidably arranged in the collection tank 30. A connecting rod 31 is fixedly connected to the lower side wall of the piston plate. A filter screen 33 is fixed to the end of the filter element tank 27. During the welding process, the suction pump is started. The suction pump captures the welding fumes through the suction hood 26 and introduces them into the cavity of the heat-conducting plate 28 through the airflow tube 25. The heat on the fumes is conducted to the heat-conducting plate 28. The cooling water in the water storage tank 29 is discharged through the drain port. The cooling water flows along the guide slope, adsorbs the heat on the heat-conducting plate 28, and the heat on the heat-conducting plate 28 is reduced rapidly. The cooled water after absorbing heat flows down automatically and is discharged from the drain port into the collection tank 30 for collection. The fumes after absorbing heat continue to flow into the filter element tank 27 and large particulate impurities in the fumes are removed by the filter screen 33.

[0020] One end of the connecting rod 31 extends through the lower side wall of the cooling tank 24 and is fixedly connected to a scraper 34 that contacts the outer wall of the filter screen 33. A telescopic spring 32 is sleeved on the outer wall of the end of the connecting rod 31. The two ends of the telescopic spring 32 are fixedly connected to the lower end of the collection tank 30 and the outer wall of the connecting rod 31, respectively. As the cooling water in the collection tank 30 increases, it continuously squeezes the piston plate, connecting rod 31, and scraper 34 downwards. The scraper 34 moves downwards along the surface of the filter screen 33, scraping away the impurities accumulated on its surface to prevent impurities from affecting the normal flow of air. Furthermore, the collection tank 30 and the water storage tank 29 can be connected by a liquid pump. The connection allows for the collection of a certain amount of cooling water in the collection tank 30, or for the water temperature to drop. The cooling water can then be pumped back to the storage tank 29 for repeated use via a liquid pump. After the cooling water is pumped back, the connecting rod 31 and the scraper 34 move upwards to reset under the reverse force of the extension spring 32. This process repeats, achieving the cooling of the flue gas and preventing damage to the filter element in the filter element tank 27 due to excessively high flue gas temperature. After cooling, the flue gas can be filtered and purified normally. During the process of cooling the flue gas by the flow of cooling water, the scraper 34 moves by collecting the cooling water, automatically cleaning large particles of impurities accumulated on the surface of the filter screen 33 and preventing clogging.
