Description

Technical Field

[0001] The present invention belongs to the technical field of welding devices, and specifically relates to a multi-functional welding head adaptation device for ship welding and its working method. Background Art

[0002] A multi-functional welding head is an advanced welding device that integrates multiple welding processes, intelligent control, and adaptive functions. It is widely used in fields such as shipbuilding, aerospace, and energy equipment to improve welding efficiency, adapt to complex working conditions, and reduce manual intervention. In view of the fact that multiple processes such as MIG (high-efficiency filling), TIG (high-quality seal welding), and laser-arc hybrid welding (deep penetration of thick plates) must be alternately used in ship welding operations, a single multi-functional welding head is difficult to adapt to all scenarios. Therefore, an adaptation device must be used to expand its functions to meet the high complexity and high reliability requirements of ship welding. After retrieval, for example, in the patent: CN219234355U, an orbital vertical straight seam welding cart with swing, including a support mechanism. The support mechanism includes two oppositely arranged support rods, and a moving track is provided inside the two support rods; a swing mechanism is provided at the top of the first extension plate, and a welding torch clamping mechanism is installed at the top of the second extension plate. This orbital vertical straight seam welding cart with swing clamps the welding torch through the welding torch clamping mechanism, then changes the welding angle of the welding torch by adjusting the fixing ring, controls the track motor through the control of the console, and realizes the rapid movement of the welding range in the horizontal and vertical directions without moving the cart. Then, through the swing mechanism, the welding torch is continuously adjusted in the horizontal direction during welding, and the weld seam is welded by the welding torch, thereby reducing the labor intensity of the staff and improving the welding accuracy of the equipment. The current welding adaptation device adjusts the position, height, and angle of the welding torch to adapt to various welding requirements. However, during the welding process, a large amount of dust containing metal particles (such as manganese, iron, and aluminum oxides) and harmful gases will be generated. These pollutants will not only pollute the air but may also directly affect the quality of the weld seam. Therefore, effective dust suction measures are crucial for environmental protection and safety. In addition, during the welding process, the welding head device itself will also generate heat (especially when working in a confined space). If not dissipated in time, it will not only accelerate the aging of the equipment, reduce its service life, but also lead to unstable welding parameters, thereby affecting the quality of the weld seam. Summary of the Invention

A dust suction pump is installed at the bottom end of the first connecting pipe. The output end of the dust suction pump is connected with an air outlet pipe. A filter cavity is arranged at the end of the air outlet pipe away from the dust suction pump. The filter cavity is opened inside the mounting seat. Exhaust pipes are evenly installed on both sides of the filter cavity. One end of each exhaust pipe is fixedly connected with a second connecting pipe. The top end of each second connecting pipe is fixedly connected with a blowing pipe.

[0005] As a further technical solution of the present invention, a filter plate is arranged inside the filter cavity, and the filter plate is slidably connected with the filter cavity through a moving component.

[0006] As a further technical solution of the present invention, the moving component includes a reciprocating lead screw embedded in the top of the filter plate. One end of the reciprocating lead screw is fixedly connected with a first gear. A second gear is meshed at the bottom end of the first gear. A turbine blade is fixedly installed inside the inner wall of the second gear. The turbine blade is arranged inside the air outlet pipe.

[0007] As a further technical solution of the present invention, the inner wall diameter of the first gear is ten N times the inner wall diameter of the second gear, and N is a positive integer.

[0008] As a further technical solution of the present invention, the second gear is rotatably installed on the outer wall of the air outlet pipe.

[0009] As a further technical solution of the present invention, a water-absorbing cotton is embedded inside the second connecting pipe, and the top end of the water-absorbing cotton is fixedly connected with the inner wall of the second connecting pipe.

[0010] As a further technical solution of the present invention, the bottom end of the water-absorbing cotton is fixedly connected with a mounting plate.

[0012] As a further technical solution of the present invention, a drain pipe is fixedly connected to the bottom end of the second connecting pipe, and a check valve is installed on the outer wall of the drain pipe.

[0013] A working method of a multi-functional welding head adapter device for ship welding includes the following steps: S1: During ship welding operations, the dust suction pump can be controlled to start by the PLC. When the dust suction pump starts, it is connected to the dust suction pipe through the first connecting pipe, causing the dust suction pipe to generate negative pressure to suck away the fume gas during welding operations, and guiding it into the outlet pipe through the outlet pipe for filtration; S2: When the gas flows in the outlet pipe, it drives the turbine blade to rotate. The rotation of the turbine blade drives the rotation of the second gear, the rotation of the second gear drives the rotation of the first gear, the rotation of the first gear drives the rotation of the reciprocating lead screw, and the rotation of the reciprocating lead screw drives the filter plate to reciprocate inside the filter chamber, reducing water flow turbulence; S3: The filtered gas is introduced into the second connecting pipe through the exhaust pipe, and then the moisture in the gas is absorbed by the absorbent cotton; S4: When the filter plate moves inside the filter chamber and contacts the inclined surface of the moving plate, it forces the moving plate to slide into the mounting seat. The movement of the moving plate drives the movement of the rack plate, the movement of the rack plate drives the rotation of the third gear, the rotation of the third gear drives the rotation of the rotating shaft, the rotation of the rotating shaft drives the rotation of the mounting plate, and the rotation of the mounting plate drives the rotation of the absorbent cotton, causing the absorbent cotton to twist itself to drain the internal moisture, and the water is re-drained into the filter chamber through the drain pipe; S5: When the filter plate moves and contacts the moving plate to drive the rotation of the rotating shaft, the coil spring is deformed under force to store elastic potential energy. When the filter plate moves away from the moving plate, the elastic potential energy is released by the coil spring to reverse the rotation of the rotating shaft, thereby reversing the absorbent cotton to reset; S6: The gas after filtration and moisture absorption finally exits from the second connecting pipe and is sprayed to both sides of the welding equipment to cool it down.

[0014] The beneficial effects of the present invention are as follows: Through the setting of the dust suction component, during ship welding operations, the dust suction pump can be controlled to start by the PLC. When the dust suction pump starts, it is connected to the dust suction pipe through the first connecting pipe, causing the dust suction pipe to generate negative pressure to suck the fume gas during welding operations into the filter chamber. The purified gas is guided through the exhaust pipe and the second connecting pipe and finally sprayed from the blow pipe to both sides of the welding equipment to cool it down. Through the above cooperation of dust suction and cooling methods, not only the problem of welding fume pollution is solved, but also the problem of overheating of the welding equipment is improved, enabling the welding equipment to be adapted to welding operations in different environments, and further improving the adaptability of the device.

[0015] In the present invention, through the arrangement of the moving components, during operation, the gas flows in the air outlet pipe to drive the turbine blades to rotate. The rotation of the turbine blades drives the rotation of the second gear, the rotation of the second gear drives the rotation of the first gear, the rotation of the first gear drives the rotation of the reciprocating lead screw, and the rotation of the reciprocating lead screw drives the filter plate to reciprocate inside the filter chamber, which helps to evenly distribute the soot particles, increase the filtration area, and thus improve the filtration efficiency.

[0016] In the present invention, through the arrangement of wringing the water out of the absorbent cotton, when the filter plate moves inside the filter chamber, the contact between the filter plate and the inclined surface of the moving plate forces the moving plate to slide into the mounting seat.

DETAILED DESCRIPTION OF THE INVENTION

[0018] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figures 1 to 8 shown, in the embodiment of the present invention, a multi-functional welding head adapter device for ship welding includes a base 1, an adjustment seat 2 and a mounting seat 3. The adjustment seat 2 is installed inside the base 1, the mounting seat 3 is fixedly installed on one side of the adjustment seat 2, a fixing plate 4 is slidably connected inside the mounting seat 3, a threaded rod 5 is threadedly connected to the inner wall on one side of the fixing plate 4, the threaded rod 5 is rotatably installed inside the mounting seat 3, a rotating block 6 is fixedly installed at the top of the threaded rod 5, and a dust suction component is arranged inside the mounting seat 3; The dust suction component includes a dust suction pipe 7 arranged inside the mounting seat 3. A plurality of dust suction pipes 7 are evenly arranged. One end of each dust suction pipe 7 is fixedly connected through a first connecting pipe 8. A dust suction pump 9 is installed at the bottom end of the first connecting pipe 8. The output end of the dust suction pump 9 is connected to an air outlet pipe 10. A filter cavity 11 is arranged at the end of the air outlet pipe 10 away from the dust suction pump 9. The filter cavity 11 is opened inside the mounting seat 3. Exhaust pipes 13 are evenly installed on both sides of the filter cavity 11. One end of each exhaust pipe 13 is fixedly connected to a second connecting pipe 12. The top end of each second connecting pipe 12 is fixedly connected to a blowing pipe 14.

[0020] Water is arranged inside the filter cavity 11 for purifying welding fumes; Through the setting of the dust suction component, during ship welding operations, the dust suction pump 9 can be controlled to start by the PLC. When the dust suction pump 9 starts, it is connected to the dust suction pipe 7 through the first connecting pipe 8, so that the dust suction pipe 7 generates negative pressure to suck the fume gas during welding operations into the filter cavity 11. The purified gas is guided through the exhaust pipe 13 and the second connecting pipe 12 and finally sprayed out from the blowing pipe 14 to both sides of the welding equipment to cool it. Through the cooperation of the above dust suction and cooling methods, not only the problem of welding fume pollution is solved, but also the problem of overheating of the welding equipment can be improved, enabling the welding equipment to be adapted to welding operations in different environments and further improving the adaptability of the device.

[0021] As Figure 3 and Figure 4 shown, a filter plate 16 is arranged inside the filter cavity 11. The filter plate 16 is slidably connected to the filter cavity 11 through a moving component.

[0022] It can not only improve the dust filtration efficiency, but also reduce the water flow turbulence and prevent the water mist from being carried out by the air flow (especially during high negative pressure dust suction).

[0023] AsFigure 4 and Figure 5 As shown in Figure 5 , the moving component includes a reciprocating lead screw 17 embedded in the top of the filter plate 16. One end of the reciprocating lead screw 17 is fixedly connected to a first gear 18. The bottom end of the first gear 18 is meshed with a second gear 19. The inner wall of the second gear 19 is fixedly installed with a turbine blade 20. The turbine blade 20 is arranged inside the air outlet pipe 10.

[0024] During operation, the gas flowing in the air outlet pipe 10 drives the turbine blade 20 to rotate. The rotation of the turbine blade 20 drives the rotation of the second gear 19. The rotation of the second gear 19 drives the rotation of the first gear 18. The rotation of the first gear 18 drives the rotation of the reciprocating lead screw 17. The rotation of the reciprocating lead screw 17 drives the filter plate 16 to reciprocate inside the filter cavity 11, which helps to evenly distribute the soot particles, increase the filtration area, and thus improve the filtration efficiency.

[0025] As Figure 4 , Figure 5 and Figure 6 shown, the inner wall diameter of the first gear 18 is ten N times that of the inner wall diameter of the second gear 19, and N is a positive integer.

[0026] The low-speed movement can reduce the collision between the filter plate 16 and the particles in the water, reduce wear, and thus extend the service life; The low-speed movement of the filter plate 16 also helps to stabilize the water flow, thereby enhancing the cooling effect on the welding equipment.

[0027] As Figure 4 , Figure 5 and Figure 6 shown, the second gear 19 is rotatably installed on the outer wall of the air outlet pipe 10.

[0028] As Figure 8 shown, a water-absorbing cotton 15 is embedded inside the second connecting pipe 12. The top end of the water-absorbing cotton 15 is fixedly connected to the inner wall of the second connecting pipe 12.

[0029] It helps to adsorb the residual soot particles in the gas and improve the filtration efficiency; The water-absorbing cotton 15 can absorb the moisture in the gas, reduce the condensation of water vapor, and prevent the water droplets from damaging the welding equipment.

[0030] As Figure 8 shown, the bottom end of the water-absorbing cotton 15 is fixedly connected to a mounting plate 23. The bottom end of the mounting plate 23 is fixedly connected to a rotating shaft 24. The bottom end of the rotating shaft 24 is fixedly installed with a third gear 25. One side of the third gear 25 is meshed with a rack plate 26. The bottom end of the rack plate 26 is fixedly installed with a moving plate 27. The moving plate 27 is arranged on one side of the filter plate 16.

[0031] Both sides of the moving plate 27 are inclined; When the filter plate 16 moves inside the filter chamber 11, the contact between the filter plate 16 and the inclined surface of the moving plate 27 forces the moving plate 27 to slide into the mounting seat 3. The movement of the moving plate 27 drives the movement of the rack plate 26, the movement of the rack plate 26 drives the rotation of the third gear 25, the rotation of the third gear 25 drives the rotation of the rotating shaft 24, the rotation of the rotating shaft 24 drives the rotation of the mounting plate 23, and the rotation of the mounting plate 23 drives the rotation of the water-absorbing cotton 15, so that the water-absorbing cotton 15 twists itself to facilitate the discharge of internal moisture and prevent water absorption saturation.

[0032] As Figure 8 shown, a torsion spring 28 is installed on the outer wall of the rotating shaft 24.

[0033] When the filter plate 16 moves and contacts the moving plate 27 to drive the rotation of the rotating shaft 24, the torsion spring 28 is deformed by force to store elastic potential energy; After the filter plate 16 moves and separates from the moving plate 27, the elastic potential energy is released by the torsion spring 28 to reverse the rotation of the rotating shaft 24, so that the water-absorbing cotton 15 is reversed to reset.

[0034] As Figure 7 shown, a drain pipe 21 is fixedly connected to the bottom end of the second connecting pipe 12, and a check valve 22 is installed on the outer wall of the drain pipe 21.

[0035] The water is re-discharged into the filter chamber 11 through the drain pipe 21.

[0036] A working method of a multi-functional welding head adaptation device for ship welding includes the following steps: S1: During ship welding operations, the dust suction pump 9 can be controlled by the PLC to start. When the dust suction pump 9 starts, it is connected to the dust suction pipe 7 through the first connecting pipe 8, so that the dust suction pipe 7 generates negative pressure to suck away the fume gas during welding operations, and is connected to the outlet pipe 10 through the outlet pipe 10 for filtration; S2: When the gas flows in the outlet pipe 10, it drives the rotation of the turbine blade 20. The rotation of the turbine blade 20 drives the rotation of the second gear 19. The rotation of the second gear 19 drives the rotation of the first gear 18. The rotation of the first gear 18 drives the rotation of the reciprocating lead screw 17. The rotation of the reciprocating lead screw 17 drives the filter plate 16 to reciprocate inside the filter chamber 11 to reduce water flow turbulence; S3: The filtered gas is introduced into the second connecting pipe 12 through the exhaust pipe 13, and then the water-absorbing cotton 15 absorbs the moisture in the gas; S4: When the filter plate 16 moves inside the filter chamber 11, the contact between the filter plate 16 and the inclined surface of the moving plate 27 forces the moving plate 27 to slide into the mounting seat 3. The movement of the moving plate 27 drives the movement of the rack plate 26, the movement of the rack plate 26 drives the rotation of the third gear 25, the rotation of the third gear 25 drives the rotation of the rotating shaft 24, the rotation of the rotating shaft 24 drives the rotation of the mounting plate 23, and the rotation of the mounting plate 23 drives the rotation of the water-absorbing cotton 15, causing the water-absorbing cotton 15 to twist itself to drain the internal moisture, and the water is re-drained into the filter chamber 11 through the drain pipe 21; S5: When the filter plate 16 moves into contact with the moving plate 27 and drives the rotating shaft 24 to rotate, the coil spring 28 is deformed by force to store elastic potential energy. When the filter plate 16 moves away from the moving plate 27, the elastic potential energy is released by the coil spring 28 to reverse the rotation of the rotating shaft 24, thereby reversing the water-absorbing cotton 15 to reset; S6: The gas after filtration and moisture absorption finally discharges from the second connecting pipe 12 and sprays to both sides of the welding equipment to cool it down.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
