Description

Technical Field

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

[0002] In the field of power construction, especially in the specialized construction of high and low voltage power supplies, cutting and welding of supports, pipes, and other components are extremely common operations. With the continuous expansion of power facility construction and the increasing demands of construction, efficient and safe welding operations have become crucial to ensuring construction quality and progress.

[0003] Then, smoke, arc and spatter will be generated during welding.

[0014] Preferably: the drive assembly includes a sleeve installed on the side wall of the shell, a piston slides inside the sleeve, the gas storage pipe and the sleeve are connected through an air supply pipe B, the bottom end of the piston is fixedly connected to a moving rod, the bottom end of the moving rod is installed with a rack, the outer wall of the regulating valve is installed with a valve stem, and one end of the valve stem is installed with a gear B meshing with the rack.

[0015] Preferably, a spring A is provided inside the sleeve, the top end of the spring A is fixedly connected to the bottom end of the piston, and the bottom end of the spring A is fixedly connected to the inner wall of the sleeve.

[0016] Preferably, a support frame is installed on the inner wall of the cylinder, a fan blade is rotatably installed on one side of the support frame, and one end of the rotating shaft is fixedly connected to one side of the fan blade.

[0017] Preferably, the top of the workbench is fixedly connected to a fixing frame, and the vibration rod is rotatably installed inside the fixing frame.

[0018] Preferably, the ventilation plate is provided with evenly distributed ventilation, and the aperture of the ventilation holes gradually decreases from the side close to the connecting pipe to the side away from the connecting pipe.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention collects the smoke gas generated by welding through a suction pump and transports it to a collection box, where the smoke gas is filtered and purified. The purified gas is transported to the inside of the air guide ring through a connecting pipe, and 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 air holes on the ventilation plate gradually decreases from the side close to the connecting pipe to the side away from the connecting pipe, the gas can be ejected in a relatively uniform and stable manner when passing through the ventilation plate, thereby forming an air curtain around the welding area. The air curtain can effectively block the smoke and welding slag generated during the welding process from diffusing 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 airflow on the welding process, and helping to improve the stability of welding quality.

[0021] 2. The present invention uses a suction pump to generate negative pressure, and then uses a suction head to promptly transmit the smoke generated during the welding process through the suction pipe A to the interior of the collection box for collection, thereby quickly and efficiently collecting the smoke generated during the welding process, greatly reducing the concentration of smoke in the working area, creating a relatively clean working environment for construction workers, reducing damage to the respiratory system caused by long-term inhalation of smoke, and ensuring the health of construction workers.

[0022] 3. The present invention generates negative pressure through a suction pump, which generates a strong suction force in the suction pipe A. Since the suction pipe A is connected to the suction pipe B, under the action of negative pressure, the external airflow will enter the cylinder, and the airflow entering the cylinder will impact the fan blades, causing the fan blades to start rotating around the rotating connection of the support frame, thereby causing the fan blades to drive the rotating shaft to rotate, and the rotating shaft drives the cam to rotate synchronously, so that the cam applies a downward thrust to the movable plate. When the raised part of the cam rotates away from the movable plate, the elastic force of the spring B will reset the movable plate upward, so that the continuous rotation of the cam causes the movable plate to move back and forth up and down on the telescopic rod, so that the movable plate synchronously drives the vibrating rod to swing synchronously around the fixed frame, thereby using the vibrating rod to continuously knock on the outer wall of the welded pipe fitting, and using vibration to make the liquid metal in the molten pool flow, breaking the surface oxide film, allowing gas to escape more easily, reducing defects such as pores, and improving the density and strength of the welding. At the same time, vibration can loosen and fall off the welding slag attached to the surface of the pipe fitting and near the weld, thereby facilitating the collection mechanism to efficiently collect the welding slag.

[0023] 4. The present invention utilizes the heat generated by the welding head. This heat is conducted to the inside of the gas storage pipe through the heat-conducting rod. After the gas in the gas storage pipe is heated, the expanded air enters the inside of the casing through the gas transmission pipe B, and the gas pushes the piston to move downward. The movement of the piston synchronously drives the rack to move, so that the movement of the rack drives the gear B to rotate, and the rotation of the gear B drives the valve stem to rotate. The rotation of the valve stem causes the adjustment valve core to move, thereby reducing the flow area inside the suction pipe A, thereby increasing the suction force of the suction pipe B. The increased suction force promotes the increase of the airflow entering the cylinder, pushing the fan blade to rotate faster. The fan blade drives the shaft and the cam sleeved thereon to increase the speed, so that the vibration frequency of the vibrating rod on the pipe becomes larger, so that the swing frequency of the vibrating rod can be adaptively adjusted according to the power of the welding head. The enhanced vibration frequency promotes the gas in the molten pool to escape more easily, so that the bubbles can leave the molten pool more quickly, thereby improving the quality of pipe welding, and eliminating the need for frequent manual adjustment of equipment parameters, saving time and labor costs, and thus improving the overall efficiency of power construction welding work.

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 invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See Figures 1 to 9 As shown, the present invention provides a welding auxiliary mechanism for electric power construction, comprising a workbench 1, a mounting frame 2 is mounted on the top of the workbench 1, a cylinder A3 is mounted on the top of the mounting frame 2, a welding head 4 is mounted on the output end of the cylinder A3, and a housing 5 is provided on the top of the workbench 1;

[0037] See Figures 1 to 5 As shown, a collection mechanism 13 for collecting smoke and dust is provided on one side of the housing 5. The collection mechanism 13 includes a suction pump 1301. An air suction pipe A1303 is installed on the side wall of the suction pump 1301. One end of the air suction pipe A1303 is connected to multiple groups of air suction heads 1304. The bottom end of the suction pump 1301 is connected to a collection box 1305. A protective air curtain mechanism 14 is provided inside the housing 5.

[0038] It should be noted that when the welding head 4 is working, the suction pump 1301 is started to generate negative pressure, and then the suction head 1304 is used to promptly transmit the smoke generated during the welding process through the suction pipe A1303 to the interior of the collection box 1305 for collection, thereby being able to quickly and efficiently collect the smoke generated during the welding process, greatly reducing the concentration of smoke in the working area, creating a relatively clean working environment for construction workers, reducing the damage to the respiratory system caused by long-term inhalation of smoke, and ensuring the health of construction workers.

[0039] See Figures 4 to 7 As shown, the outer wall of the suction pipe A1303 is provided with an adjustment mechanism 15 for adjusting the suction force. The adjustment mechanism 15 includes a regulating valve 1501. A heat-conducting rod 1502 is installed on the outer wall of the welding head 4. An air storage pipe 1503 is installed at one end of the heat-conducting rod 1502. A driving component for controlling the opening and closing of the regulating valve 1501 is provided between the regulating valve 1501 and the air storage pipe 1503.

[0040] See Figures 7 and 8 As shown, both sides of the collecting box 1305 are connected with a vibrating mechanism 16 of a vibrating pipe fitting, the vibrating mechanism 16 includes a cylinder 1601, a rotating shaft 1604 is rotated inside the cylinder 1601, the outer wall of the rotating shaft 1604 is provided with a cam 1605, a telescopic rod 1606 is installed on the top of the workbench 1, a movable plate 1607 is installed on the top of the telescopic rod 1606, the outer wall of the telescopic rod 1606 is provided with a spring B1608, and vibrating rods 1609 are hinged on both sides of the movable plate 1607, and the cylinder 1601 and the collecting box 1305 are connected through an air intake pipe B1611.

[0041] It should be noted that when the suction pump 1301 is started, negative pressure begins to be generated, which generates 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, the external air flow will enter the cylinder 1601, and the air flow entering the cylinder 1601 will impact the fan blades 1603, causing the fan blades 1603 to start rotating around the rotating connection of the support frame 1602, and then the fan blades 1603 drive the rotating shaft 1604 to rotate synchronously. As the rotating shaft 1604 rotates, the cam 1605 mounted on the outer wall of the rotating shaft 1604 rotates synchronously, and the raised part of the cam 1605 contacts the movable plate 1607, so that the cam 1605 applies a downward thrust to the movable plate 1607, so that the movable plate 1607 overcomes the elastic force of the spring B1608, so that the movable plate 1607 The movable plate 1607 moves downward along the telescopic rod 1606. When the raised part of the cam 1605 rotates away from the movable plate 1607, the elastic force of the spring B1608 will reset the movable plate 1607 upward, so that the continuous rotation of the cam 1605 causes the movable plate 1607 to move back and forth up and down on the telescopic rod 1606, so that the movable plate 1607 synchronously drives the vibration rod 1609 to swing synchronously around the fixed frame 1610, so that the vibration rod 1609 is used to continuously knock on 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 it easier for the gas 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, thereby facilitating the collection mechanism 13 to efficiently collect the welding slag.

[0042] See Figures 1 to 3 As shown, two groups of symmetrically arranged slide grooves are provided at the top of the workbench 1, an electric push rod 6 is installed inside the slide groove, a mounting plate 7 is slidingly provided 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, and a gear A12 meshing with the gear ring 8 is installed at the output end of the motor 11.

[0043] See Figure 2 As shown, the inner wall of the gear ring 8 is fixedly connected to multiple groups of cylinders B9, and the output ends of the multiple groups of cylinders B9 are installed with clamping plates 10.

[0044] It should be noted that when pipes need to be butt-welded, the pipes are first placed inside the mounting plate 7, and then the cylinder A3 is started, so that the cylinder A3 drives the clamping plate 10 to fix the pipes, thereby avoiding shaking or displacement of the pipes during the welding process, thereby improving the stability of the welding process. After the pipes are butt-welded, the welding head 4 is started 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 ring gear 8, the rotational force of the gear A12 is transmitted to the ring gear 8, which in turn drives the ring gear 8 to rotate at a uniform speed around its own axis, so that the rotation of the ring gear 8 can drive the pipes to rotate synchronously and at a uniform speed. When the welding head 4 remains in a fixed position, the uniform rotation of the pipe enables the welding part to pass through the welding head 4 evenly, thereby realizing continuous welding of the entire circumferential weld.

[0045] See Figure 1 As shown, the outer wall of the welding head 4 is provided with a protective cover 1302 .

[0046] See Figure 6 As shown, the air curtain mechanism 14 includes an air guide ring 1401 installed at both ends of the shell 5, the collection box 1305 and the air guide ring 1401 are connected through the air supply pipe A1402, the side wall of the air guide ring 1401 is connected to the connecting pipe 1403, one side of the connecting pipe 1403 is connected to the ring spray frame 1404, and the interior of the ring spray frame 1404 is installed with a ventilation plate 1405.

[0047] It should be noted that when the collection mechanism 13 is operating, the suction pump 1301 collects the smoke gas generated by welding and transports it to the collection box 1305, and the smoke gas is filtered and purified in the collection box 1305. The purified gas is transmitted to the inside of the air guide ring 1401 through the connecting pipe 1403, and the gas enters the ring spray rack 1404 from the side wall of the air guide ring 1401 through the connecting pipe 1403. Since the aperture of the air holes on the air vent plate 1405 gradually decreases from the side close to the connecting pipe 1403 to the side away from the connecting pipe 1403, the gas can be ejected in a relatively uniform and stable manner when passing through the air vent plate 1405, thereby forming an air curtain around the welding area, so that the air curtain can effectively prevent the smoke and welding slag generated during the welding process from diffusing 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 isolation and protection role for the welding area, reduces the interference of external airflow on the welding process, and helps to improve the stability of welding quality.

[0048] In addition, the gas outlet of the ring spray rack 1404 is set at an angle, so that the ejected gas can be blown along the surface of the pipe toward the welding molten pool, thereby using the airflow to cool the weld, which can quickly cool the molten pool area, accelerate the solidification speed of the weld metal, and reduce the possibility of defects such as pores and cracks in the weld.

[0049] See Figure 7 As shown, the drive assembly includes a sleeve 1504 installed on the side wall of the shell 5, a piston 1505 slides inside the sleeve 1504, the air storage pipe 1503 and the sleeve 1504 are connected through the air supply pipe B1506, the bottom end of the piston 1505 is fixedly connected to the moving rod 1507, the bottom end of the moving rod 1507 is installed with a rack 1508, the outer wall of the regulating valve 1501 is installed with a valve stem 1509, and one end of the valve stem 1509 is installed with a gear B1510 meshing with the rack 1508.

[0050] It should be noted that according to the difference in wall thickness of different pipe fittings, the power of the welding head 4 will change accordingly during welding, which will cause different heat generated by the welding head 4. When the wall thickness of the pipe fitting is thicker, the welding head 4 will generate more heat when working. This heat is conducted to the inside of the gas storage pipe 1503 through the heat-conducting rod 1502. After the gas in the gas storage pipe 1503 is heated, the volume of the gas continues to expand. The expanded air enters the inside of the sleeve 1504 through the gas pipe B1506. The gas pushes the piston 1505 to move downward. The movement of the piston 1505 synchronously drives the rack 1508 to move. Since the rack 1508 is engaged 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 stem 1509 to rotate. The rotation of the valve stem 1509 will cause the adjustment The valve core of the section moves, thereby reducing the flow area inside the suction pipe A1303, increasing the suction force of the gas, and further increasing the suction force of the suction pipe B1611. The increased suction force causes the airflow entering the cylinder 1601 to be enhanced, pushing the fan blade 1603 to rotate faster, and the fan blade 1603 drives the rotating shaft 1604 and the cam 1605 mounted thereon to increase the rotation speed, so that the vibration frequency of the vibration rod 1609 on the pipe fitting becomes larger, so that the swing frequency of the vibration rod 1609 can be adaptively adjusted according to the power of the welding head 4. The enhanced vibration frequency promotes the gas in the molten pool to escape more easily, and the bubbles can be separated from the molten pool more quickly, thereby improving the quality of pipe welding, and there is no need for manual frequent adjustment of equipment parameters, saving time and labor costs, and thus improving the overall efficiency of power construction welding work.

[0051] See Figure 7 As shown, a spring A1511 is provided 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 .

[0052] See Figure 9 As shown, a support frame 1602 is installed on the inner wall of the cylinder 1601 , a fan blade 1603 is rotatably installed on one side of the support frame 1602 , and one end of the rotating shaft 1604 is fixedly connected to one side of the fan blade 1603 .

[0053] See Figure 9 As shown, the top of the workbench 1 is fixedly connected to a fixing frame 1610 , and the vibration rod 1609 is rotatably installed inside the fixing frame 1610 .

[0054] See Figure 6 As shown, the ventilation plate 1405 is provided with evenly distributed ventilation, and the aperture of the ventilation holes gradually decreases from the side close to the connecting pipe 1403 to the side away from the connecting pipe 1403.

[0055] Working principle: When pipes need to be butt-welded, first place the pipes inside the mounting plate 7, then start the cylinder A3, so that the cylinder A3 drives the clamping plate 10 to fix the pipes, thereby avoiding shaking or displacement of the pipes during the welding process, thereby improving the stability of the welding process. After the pipes are butt-welded, 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 ring gear 8, the rotational force of the gear A12 is transmitted to the ring gear 8, thereby driving the ring gear 8 to rotate at a uniform speed around its own axis, so that the rotation of the ring gear 8 can drive the pipes to rotate synchronously at a uniform speed. When the welding head 4 remains in a fixed position, the uniform rotation of the pipes enables the welding part to pass through the welding head 4 evenly, thereby realizing continuous welding of the entire circumferential weld.

[0056] When the welding head 4 is working, the suction pump 1301 is started to generate negative pressure, and then the smoke generated during the welding process is promptly transferred to the interior of the collection box 1305 through the suction pipe A1303 by the suction head 1304 for collection. In this way, the smoke generated during the welding process can be collected quickly and efficiently, greatly reducing the concentration of smoke in the working area, creating a relatively clean working environment for the construction workers, reducing the damage to the respiratory system caused by long-term inhalation of smoke, and protecting the health of the construction workers.

[0057] When the collecting mechanism 13 is in operation, the suction pump 1301 collects the smoke gas generated by welding and transports it to the collecting box 1305. The smoke gas is filtered and purified in the collecting box 1305, and the purified gas is transported to the inside of the air guide ring 1401 through the connecting pipe 1403. The gas enters the ring spray rack 1404 from the side wall of the air guide ring 1401 through the connecting pipe 1403. Since the aperture of the air holes on the air vent plate 1405 gradually decreases from the side close to the connecting pipe 1403 to the side away from the connecting pipe 1403, the gas can be ejected in a relatively uniform and stable manner when passing through the air vent plate 1405, thereby forming an air curtain around the welding area. The air curtain can effectively prevent the smoke and welding slag generated during the welding process from diffusing 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 airflow on the welding process, and helping to improve the stability of welding quality.

[0058] At the same time, when the suction pump 1301 is started, negative pressure begins to be generated, which generates 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, the external air flow will enter the cylinder 1601, and the air flow entering the cylinder 1601 will impact the fan blades 1603, causing the fan blades 1603 to start rotating around the rotating connection of the support frame 1602, and then the fan blades 1603 drive the rotating shaft 1604 to rotate synchronously. As the rotating shaft 1604 rotates, the cam 1605 mounted on the outer wall of the rotating shaft 1604 rotates synchronously, and the raised part of the cam 1605 contacts the movable plate 1607, so that the cam 1605 applies a downward thrust to the movable plate 1607, so that the movable plate 1607 overcomes the elastic force of the spring B1608, so that the movable plate 1607 moves downward along the telescopic rod 1606. When the raised part of the cam 1605 rotates away from the movable plate 1607, the elastic force of the spring B1608 will reset the movable plate 1607 upward, so that the continuous rotation of the cam 1605 causes the movable plate 1607 to move back and forth up and down on the telescopic rod 1606, so that the movable plate 1607 synchronously drives the vibration rod 1609 to swing synchronously around the fixed frame 1610, so that the vibration rod 1609 is used to continuously knock on 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 it easier for the gas 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 that the collection mechanism 13 can collect the welding slag efficiently.

[0059] In addition, according to the difference in wall thickness of different pipe fittings, the power of the welding head 4 will change accordingly during welding, thereby causing the heat generated by the welding head 4 to be different. When the wall thickness of the pipe fitting is thicker, the welding head 4 will generate more heat when working. This heat is conducted to the inside of the gas storage pipe 1503 through the heat-conducting rod 1502. After the gas in the gas storage pipe 1503 is heated, the volume of the gas continues to expand. The expanded air enters the inside of the sleeve 1504 through the gas pipe B1506. The gas pushes the piston 1505 to move downward. The movement of the piston 1505 synchronously drives the rack 1508 to move. Since the rack 1508 is engaged 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 stem 1509 to rotate. The rotation of the valve stem 1509 will adjust the The valve core moves, thereby reducing the flow area inside the suction pipe A1303, increasing the suction force of the gas, and further increasing the suction force of the suction pipe B1611. The increased suction force causes the airflow entering the cylinder 1601 to be enhanced, pushing the fan blade 1603 to rotate faster, and the fan blade 1603 drives the rotating shaft 1604 and the cam 1605 mounted thereon to increase the rotation speed, so that the vibration frequency of the vibration rod 1609 on the pipe fitting becomes larger, so that the swing frequency of the vibration rod 1609 can be adaptively adjusted according to the power of the welding head 4. The enhanced vibration frequency makes it easier for the gas in the molten pool to escape, and the bubbles can be separated from the molten pool more quickly, thereby improving the quality of pipe welding, and eliminating the need for frequent manual adjustment of equipment parameters, saving time and labor costs, and thereby improving the overall efficiency of power construction welding work.
