Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction, and particularly to a welding auxiliary mechanism for electric power construction. Background Art

[0002] In the field of electric power construction, especially in the construction links of high and low voltage power supply, cutting and welding of brackets, pipelines, etc. are extremely common operations. With the continuous expansion of the scale of electric power facility construction and the increasing improvement of construction requirements, efficient and safe welding operations have become the key to ensuring construction quality and progress.

[0003] However, during welding, smoke and dust, arc light and spatter are generated. These generated smoke and dust will not only seriously affect the respiratory health of welders, and long-term inhalation may cause occupational diseases such as pneumoconiosis, but also the smoke and dust will pollute the working environment, and the spatter is also likely to cause injuries to welders.

[0004] In view of this, research and improvement are carried out on the existing problems, and a welding auxiliary mechanism for electric power construction is provided, aiming to solve the problems and improve the practical value through this technology. Summary of the Invention

[0005] The purpose of the present invention is to solve the disadvantages existing in the prior art, and a welding auxiliary mechanism for electric power construction is proposed. The present invention generates negative pressure through a suction pump, and the suction head efficiently collects smoke and dust into the collection box. The purified gas forms an air curtain to block the diffusion of smoke and dust and welding slag, purify the air and isolate the welding area. The suction force of the suction pump can also drive the vibration mechanism, and the vibration rod is knocked against the pipe fittings by the fan blade, cam, etc., to improve the welding quality and facilitate the collection of welding slag. In addition, the heat conduction of the welding head causes the gas in the gas storage pipe to expand, automatically adjusting the suction force of the suction pipe and the frequency of the vibration rod, improving the welding quality and efficiency, and eliminating the need for manual frequent parameter adjustment.

[0009] Preferably: A protective cover is sleeved on the outer wall of the welding head.

[0010] Preferably: The air curtain mechanism includes air guide rings installed at both ends of the shell. The collection box and the air guide rings are connected through an air delivery pipe A. A connecting pipe is communicated with the side wall of the air guide ring. A ring spray frame is communicated with one side of the connecting pipe. An air vent plate is installed inside the ring spray frame.

[0011] Preferably: The driving component includes a sleeve installed on the side wall of the shell. A piston slides inside the sleeve. The air storage pipe and the sleeve are connected through an air delivery pipe B. A moving rod is fixedly connected to the bottom end of the piston. A rack is installed at the bottom end of the moving rod. A valve rod is installed on the outer wall of the regulating valve. A gear B meshing with the rack is installed at one end of the valve rod.

[0012] Preferably: A spring A is arranged inside the sleeve. The top end of the spring A is fixedly connected to the bottom end of the piston. The bottom end of the spring A is fixedly connected to the inner wall of the sleeve.

[0013] Preferably: A support frame is installed on the inner wall of the cylinder body. A fan blade is rotatably installed on one side of the support frame. One end of the rotating shaft is fixedly connected to one side of the fan blade.

[0014] Preferably: A fixed frame is fixedly connected to the top end of the workbench. The vibration rod is rotatably installed inside the fixed frame.

[0015] Preferably: The air vent plate is provided with uniformly distributed air vents, and the aperture of the air vent holes gradually becomes smaller from the side close to the connecting pipe to the side far from the connecting pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. After the fume gas generated by welding is collected and transported to the collection box by the suction pump in the present invention, the fume gas is filtered and purified in the collection box. The purified gas is transmitted into the inner part of the air guide ring through the connecting pipe. The gas enters the ring spray rack from the side wall of the air guide ring through the connecting pipe. Since the aperture of the ventilation holes on the ventilation plate gradually becomes smaller from the side close to the connecting pipe to the side far from the connecting pipe, when the gas passes through the ventilation plate, it can be ejected in a relatively uniform and stable manner, so as to form an air curtain around the welding area. Thus, the air curtain can effectively block the fume and welding slag generated during welding from spreading to the surrounding environment, further purifying the air in the working area and creating a healthier and safer working environment for the operators. At the same time, the air curtain plays a certain role in isolating and protecting the welding area, reducing the interference of external air flow on the welding process and helping to improve the stability of welding quality.

[0017] 2. In the present invention, through the suction pump, negative pressure is generated by the suction pump. Then, the suction head is used to timely transport the fume generated during welding to the inside of the collection box through the suction pipe A for collection, so as to quickly and efficiently collect the fume generated during welding, greatly reducing the concentration of fume in the working area, creating a relatively clean working environment for the construction workers, reducing the damage to the respiratory system and the like caused by long-term inhalation of fume, and ensuring the physical health of the construction workers.

[0018] 3. In the present invention, negative pressure is generated by the suction pump, so that a strong suction force is generated in the suction pipe A. Since the suction pipe A is communicated with the suction pipe B, under the action of negative pressure, the external air flow will enter the cylinder body. The air flow entering the cylinder body will impact the fan blade, causing the fan blade to start rotating around the rotating connection of the support frame. Then, the fan blade drives the rotating shaft to rotate, and the rotating shaft drives the cam to rotate synchronously, so that the cam exerts a downward thrust on the movable plate. When the convex part of the cam turns away from the movable plate, the elastic force of the spring B will make the movable plate reset upward. Thus, the continuous rotation of the cam makes the movable plate move up and down reciprocally on the telescopic rod, so that the movable plate synchronously drives the vibrating rod to swing synchronously inside the fixed frame. Therefore, the vibrating rod is used to continuously knock the outer wall of the welded pipe fitting, and the vibration is used to make the liquid metal in the molten pool flow, break the surface oxide film, make the gas more likely to escape, reduce defects such as pores, and improve the density and strength of the welding. At the same time, the vibration can loosen and fall off the welding slag attached to the surface of the pipe fitting and near the weld, so as to facilitate the efficient collection of the welding slag by the collection mechanism.

[0019] 4. The present invention utilizes the heat generated by the welding head. This heat is conducted through the heat-conducting rod to the interior of the gas storage pipe. After the gas in the gas storage pipe is heated, the expanded air enters the interior of the sleeve through the air delivery pipe B. The gas pushes the piston to move downward, and the movement of the piston synchronously drives the movement of the rack, causing the movement of the rack to drive the rotation of gear B. The rotation of gear B drives the rotation of the valve stem, and the rotation of the valve stem causes the regulating valve core to move, thereby reducing the flow area inside the air intake pipe A, increasing the suction force of the air intake pipe B. The increased suction force prompts the airflow entering the cylinder to strengthen, pushing the fan blade to rotate faster. The fan blade drives the rotation speed of the rotating shaft and the cam sleeved thereon to increase, causing the vibration frequency of the vibrating rod on the pipe fitting to become larger. Thus, the swinging frequency of the vibrating rod can be adaptively adjusted according to the power of the welding head. By enhancing the vibration frequency, it is easier for the gas in the molten pool to escape, enabling the bubbles to break away from the molten pool more quickly, thereby improving the welding quality of the pipe fitting. And there is no need to frequently adjust the equipment parameters manually, saving time and labor costs, and further improving the overall efficiency of the welding work in electric power construction.

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. 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.

[0023] Refer to Figures 1 to 9 As shown, the present invention provides a welding auxiliary mechanism for electric power construction, including a workbench 1. A mounting frame 2 is installed at the top end of the workbench 1. A cylinder A 3 is installed at the top end of the mounting frame 2. A welding head 4 is installed at the output end of the cylinder A 3. A housing 5 is arranged at the top end of the workbench 1; Refer to Figures 1 to 5 As shown, a collection mechanism 13 for collecting welding fumes is arranged on one side of the housing 5. The collection mechanism 13 includes a suction pump 1301. A suction pipe A 1303 is installed on the side wall of the suction pump 1301. One end of the suction pipe A 1303 communicates with a plurality of suction heads 1304. The bottom end of the suction pump 1301 communicates with a collection box 1305. An air curtain mechanism 14 for protection is arranged inside the housing 5; It should be noted that when the welding head 4 is working, the suction pump 1301 is started to generate negative pressure in the suction pump 1301. Then, the suction head 1304 is used to timely transfer the fumes generated during the welding process through the suction pipe A1303 to the inside of the collection box 1305 for collection. Thus, the fumes generated during the welding process can be collected quickly and efficiently, greatly reducing the concentration of fumes in the working area, creating a relatively clean working environment for the construction workers, reducing the damage to the respiratory system and the like caused by long-term inhalation of fumes, and ensuring the physical health of the construction workers.

[0024] Refer to Figures 4 to 7 As shown, an adjusting mechanism 15 for adjusting the suction force is provided on the outer wall of the suction pipe A1303. The adjusting mechanism 15 includes a regulating valve 1501. A heat-conducting rod 1502 is installed on the outer wall of the welding head 4, and a gas storage pipe 1503 is installed at one end of the heat-conducting rod 1502. A driving assembly for controlling the opening and closing of the regulating valve 1501 is provided between the regulating valve 1501 and the gas storage pipe 1503; Refer to Figures 7 to 8 As shown, a vibrating mechanism 16 of a vibrating pipe fitting is communicated on both sides of the collection box 1305. The vibrating mechanism 16 includes a cylinder body 1601. A rotating shaft 1604 is rotated inside the cylinder body 1601. A cam 1605 is sleeved on the outer wall of the rotating shaft 1604. A telescopic rod 1606 is installed at the top end of the workbench 1. A movable plate 1607 is installed at the top end of the telescopic rod 1606. A spring B1608 is sleeved on the outer wall of the telescopic rod 1606. Vibrating rods 1609 are hinged on both sides of the movable plate 1607. The cylinder body 1601 and the collection box 1305 are communicated through a suction pipe B1611.

[0025] It should be noted that after the suction pump 1301 is started, negative pressure is generated, resulting in a strong suction force in the suction pipe A1303. Since the suction pipe A1303 is connected to the suction pipe B1611, under the action of negative pressure, external air flow will enter the cylinder body 1601. The air flow entering the cylinder body 1601 will impact the fan blade 1603, causing the fan blade 1603 to start rotating around the rotation connection of the support frame 1602. Furthermore, the fan blade 1603 drives the rotating shaft 1604 to rotate synchronously. As the rotating shaft 1604 rotates, the cam 1605 sleeved on the outer wall of the rotating shaft 1604 rotates synchronously. The protruding part of the cam 1605 contacts the movable plate 1607, applying a downward thrust to the movable plate 1607, causing the movable plate 1607 to overcome the elastic force of the spring B1608 and move downward along the telescopic rod 1606. When the protruding part of the cam 1605 rotates away from the movable plate 1607, the elastic force of the spring B1608 will cause the movable plate 1607 to reset upward. Thus, the continuous rotation of the cam 1605 causes the movable plate 1607 to reciprocate up and down on the telescopic rod 1606, causing the movable plate 1607 to drive the vibrating rod 1609 to swing synchronously within the fixed frame 1610. Thereby, the vibrating rod 1609 continuously knocks on the outer wall of the welded pipe fitting, using vibration to make the liquid metal in the molten pool flow, break the surface oxide film, make it easier for gas to escape, reduce defects such as pores, and improve the density and strength of the welding. At the same time, vibration can loosen and detach the welding slag adhering to the surface of the pipe fitting and near the weld, facilitating the efficient collection of the welding slag by the collection mechanism 13.

[0026] Refer to Figures 1 to 3 As shown, two groups of symmetrically arranged chutes are opened at the top of the workbench 1. An electric push rod 6 is installed inside the chute. A mounting plate 7 slides on the outer wall of the electric push rod 6. A gear ring 8 is rotatably installed inside the mounting plate 7. A motor 11 is installed on one side of the mounting plate 7. The output end of the motor 11 is installed with a gear A12 meshing with the gear ring 8.

[0027] Refer to Figure 2 As shown, a plurality of cylinder B9s are fixedly connected to the inner wall of the gear ring 8. The output ends of the plurality of cylinder B9s are installed with clamping plates 10.

[0028] It should be noted that when welding pipe fittings, first place the pipe fittings inside the mounting plate 7, and then start the cylinder A3, so that the cylinder A3 drives the clamping plate 10 to fix the pipe fittings, thereby avoiding the situation of shaking or displacement of the pipe fittings during the welding process, improving the stability of the welding process. After the butt joint of the pipe fittings is completed, start the welding head 4 to start the welding operation. At the same time, the motor 11 is also turned on synchronously, so that the motor 11 drives the gear A12 to rotate. Due to the meshing transmission relationship between the gear A12 and the gear ring 8, the rotational force of the gear A12 is transmitted to the gear ring 8, thereby driving the gear ring 8 to rotate uniformly around its own axis, so that the rotation of the gear ring 8 can drive the pipe fittings to rotate synchronously and uniformly. With the welding head 4 maintaining a fixed position, the uniform rotation of the pipe fittings enables the welding part to pass through the welding head 4 evenly, thereby realizing the continuous welding of the entire circumferential weld.

[0029] Refer to Figure 1 As shown, a protective cover 1302 is sleeved on the outer wall of the welding head 4.

[0030] Refer to Figure 6 As shown, the air curtain mechanism 14 includes air guide rings 1401 installed at both ends of the housing 5. The collection box 1305 is communicated with the air guide ring 1401 through an air delivery pipe A1402. A connecting pipe 1403 is communicated with the side wall of the air guide ring 1401. One side of the connecting pipe 1403 is communicated with an annular spray frame 1404, and an air vent plate 1405 is installed inside the annular spray frame 1404.

[0031] It should be noted that when the collection mechanism 13 operates, the suction pump 1301 collects and conveys the fume gas generated by welding to the collection box 1305. After that, the fume gas in the collection box 1305 is filtered and purified. The purified gas is transmitted to the inside of the air guide ring 1401 through the connecting pipe 1403. The gas enters the annular spray frame 1404 from the side wall of the air guide ring 1401 through the connecting pipe 1403. Since the aperture of the air vent holes on the air vent plate 1405 gradually becomes smaller from the side close to the connecting pipe 1403 to the side far from the connecting pipe 1403, when the gas passes through the air vent plate 1405, it can be ejected in a relatively uniform and stable manner, thereby forming an air curtain around the welding area. Thus, the air curtain can effectively block the fume and welding slag generated during the welding process from spreading to the surrounding environment, further purifying the air in the working area and creating a healthier and safer working environment for the operators. At the same time, the air curtain plays a certain role in isolating and protecting the welding area, reducing the interference of external air flow on the welding process and helping to improve the stability of the welding quality.

[0032] In addition, the air outlet of the annular spray rack 1404 is inclined, so that the sprayed gas can blow along the surface of the pipe fitting towards the welded molten pool, thereby using the air flow to cool the weld, enabling the molten pool area to cool rapidly, accelerating the solidification speed of the weld metal, and reducing the possibility of defects such as pores and cracks in the weld.

[0033] Refer to Figure 7 As shown, the driving assembly includes a sleeve 1504 installed on the side wall of the housing 5. A piston 1505 slides inside the sleeve 1504. The gas storage pipe 1503 is communicated with the sleeve 1504 through an air delivery pipe B1506. A moving rod 1507 is fixedly connected to the bottom end of the piston 1505. A rack 1508 is installed at the bottom end of the moving rod 1507. A valve rod 1509 is installed on the outer wall of the regulating valve 1501. A gear B1510 meshing with the rack 1508 is installed at one end of the valve rod 1509.

[0034] It should be noted that according to the wall thickness differences of different pipe fittings, the power of the welding head 4 will change accordingly during welding, and thus the heat generated by the welding head 4 will be different. When the wall thickness of the pipe fitting is relatively thick, the welding head 4 will generate more heat during operation. These heats are conducted through the heat conducting rod 1502 into the interior of the gas storage pipe 1503. After the gas in the gas storage pipe 1503 is heated, the volume of the gas continuously expands. The expanded air enters the interior of the sleeve 1504 through the air delivery pipe B1506. The gas pushes the piston 1505 to move downward. The movement of the piston 1505 drives the rack 1508 to move synchronously. Since the rack 1508 meshes with the gear B1510, the movement of the rack 1508 drives the gear B1510 to rotate. The rotation of the gear B1510 drives the valve rod 1509 to rotate. The rotation of the valve rod 1509 will cause the valve core of the regulator to move, thereby reducing the flow area inside the air suction pipe A1303, increasing the suction of the gas, further increasing the suction of the air suction pipe B1611. The increased suction prompts the air flow entering the cylinder 1601 to strengthen, pushing the fan blade 1603 to rotate faster. The fan blade 1603 drives the rotating speed of the rotating shaft 1604 and the cam 1605 sleeved thereon to increase, making the vibration frequency of the vibrating rod 1609 on the pipe fitting larger. Thus, the swinging frequency of the vibrating rod 1609 can be adaptively adjusted according to the power of the welding head 4. By enhancing the vibration frequency, it is easier for the gas in the molten pool to escape, enabling the bubbles to break away from the molten pool more quickly, thereby improving the welding quality of the pipe fitting, and there is no need to manually adjust the equipment parameters frequently, saving time and labor costs, and further improving the overall efficiency of the electric power construction welding work.

[0035] Refer to Figure 7 As shown, a spring A1511 is arranged inside the sleeve 1504. The top end of the spring A1511 is fixedly connected to the bottom end of the piston 1505, and the bottom end of the spring A1511 is fixedly connected to the inner wall of the sleeve 1504.

[0036] Refer to Figure 9 As shown, a support frame 1602 is installed on the inner wall of the cylinder body 1601. A fan blade 1603 is rotatably installed on one side of the support frame 1602. One end of a rotating shaft 1604 is fixedly connected to one side of the fan blade 1603.

[0037] Refer to Figure 9 As shown, a fixed frame 1610 is fixedly connected to the top end of the workbench 1. A vibrating rod 1609 is rotatably installed inside the fixed frame 1610.

[0038] Refer to Figure 6 As shown, the ventilation plate 1405 is provided with uniformly distributed ventilation holes, and the aperture of the ventilation holes gradually becomes smaller from the side close to the connecting pipe 1403 to the side far from the connecting pipe 1403.

[0039] Working principle: When welding pipe fittings, first place the pipe fittings inside the mounting plate 7, and then start the cylinder A3, so that the cylinder A3 drives the clamping plate 10 to fix the pipe fittings, thereby avoiding the situation of shaking or displacement of the pipe fittings during the welding process, improving the stability of the welding process. After the pipe fittings are butted, start the welding head 4 to start the welding operation. At the same time, the motor 11 is also started synchronously, so that the motor 11 drives the gear A12 to rotate. Due to the meshing transmission relationship between the gear A12 and the gear ring 8, the rotational force of the gear A12 is transmitted to the gear ring 8, and then drives the gear ring 8 to rotate uniformly around its own axis, so that the rotation of the gear ring 8 can drive the pipe fittings to rotate synchronously and uniformly. When the welding head 4 remains in a fixed position, the uniform rotation of the pipe fittings enables the welding part to pass through the welding head 4 evenly, thereby realizing continuous welding of the entire circumferential weld; When the welding head 4 is working, start the suction pump 1301, so that the suction pump 1301 generates negative pressure, and then use the suction head 1304 to timely transmit the dust generated during the welding process through the suction pipe A1303 to the inside of the collection box 1305 for collection, so as to quickly and efficiently collect the dust generated during the welding process, greatly reducing the dust concentration in the working area, creating a relatively clean working environment for the construction workers, reducing the damage to the respiratory system and the like caused by long-term inhalation of dust, and protecting the physical health of the construction workers; When the collection mechanism 13 operates, after the suction pump 1301 collects and conveys the fume gas generated by welding to the collection box 1305, the fume gas in the collection box 1305 is filtered and purified. The purified gas is transmitted through the connecting pipe 1403 to the inside of the air guide ring 1401, and the gas enters the annular spray frame 1404 from the side wall of the air guide ring 1401 through the connecting pipe 1403. Since the aperture of the ventilation holes on the ventilation plate 1405 gradually decreases from the side close to the connecting pipe 1403 to the side far from the connecting pipe 1403, when the gas passes through the ventilation plate 1405, it can be ejected in a relatively uniform and stable manner, thereby forming an air curtain around the welding area. Thus, the air curtain can effectively block the fume and welding slag generated during welding from spreading to the surrounding environment, further purifying the air in the working area and creating a healthier and safer working environment for the operator. At the same time, the air curtain plays a certain role in isolating and protecting the welding area, reducing the interference of external airflows on the welding process and helping to improve the stability of welding quality; At the same time, when the suction pump 1301 starts, a negative pressure is generated, resulting in a strong suction force in the suction pipe A 1303. Since the suction pipe A 1303 is connected to the suction pipe B 1611, under the action of the negative pressure, the external airflow will enter the cylinder 1601. The airflow entering the cylinder 1601 will impact the fan blade 1603, causing the fan blade 1603 to start rotating around the rotation connection of the support frame 1602. Then, the fan blade 1603 drives the rotating shaft 1604 to rotate synchronously. As the rotating shaft 1604 rotates, the cam 1605 sleeved on the outer wall of the rotating shaft 1604 rotates synchronously. The convex part of the cam 1605 contacts the movable plate 1607, applying a downward thrust to the movable plate 1607, causing the movable plate 1607 to overcome the elastic force of the spring B 1608 and move downward along the telescopic rod 1606. When the convex part of the cam 1605 turns away from the movable plate 1607, the elastic force of the spring B 1608 will cause the movable plate 1607 to reset upward. Thus, the continuous rotation of the cam 1605 causes the movable plate 1607 to move reciprocally up and down on the telescopic rod 1606, causing the movable plate 1607 to drive the vibrating rod 1609 to swing synchronously within the fixed frame 1610. Thus, the vibrating rod 1609 continuously knocks on the outer wall of the welded pipe fitting, using vibration to make the liquid metal in the molten pool flow, break the surface oxide film, make the gas more likely to escape, reduce defects such as pores, and improve the density and strength of the welding. At the same time, the vibration can loosen and detach the welding slag attached to the surface of the pipe fitting and near the weld, facilitating the efficient collection of the welding slag by the collection mechanism 13.

[0040] In addition, according to the wall thickness differences of different pipe fittings, the power of the welding head 4 will change accordingly during welding, thereby resulting in different amounts of heat generated by the welding head 4. When the wall thickness of the pipe fitting is relatively thick, the welding head 4 will generate more heat during operation. These heats are conducted through the heat conduction rod 1502 to the inside of the gas storage pipe 1503. After the gas in the gas storage pipe 1503 is heated, the volume of the gas continuously expands. The expanded air enters the inside of the sleeve 1504 through the air delivery pipe B1506. The gas pushes the piston 1505 to move downward, and the movement of the piston 1505 synchronously drives the movement of the rack 1508. Since the rack 1508 meshes with the gear B1510, the movement of the rack 1508 drives the rotation of the gear B1510. The rotation of the gear B1510 drives the rotation of the valve rod 1509. The rotation of the valve rod 1509 causes the adjusted valve core to move, thereby reducing the flow area inside the air suction pipe A1303, increasing the suction of the gas, and further increasing the suction of the air suction pipe B1611. The increased suction prompts the airflow entering the cylinder body 1601 to strengthen, pushing the fan blade 1603 to rotate faster. The fan blade 1603 drives the rotation speed of the rotating shaft 1604 and the cam 1605 sleeved thereon to increase, making the vibration frequency of the vibration rod 1609 on the pipe fitting larger. Thus, the swing frequency of the vibration rod 1609 can be adaptively adjusted according to the power of the welding head 4. By enhancing the vibration frequency, it is easier for the gas in the molten pool to escape, enabling the bubbles to break away from the molten pool more quickly, thereby improving the welding quality of the pipe fitting. Moreover, there is no need to manually adjust the equipment parameters frequently, saving time and labor costs, and further improving the overall efficiency of the electric power construction welding work.
