Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction, and particularly relates to a welding device for electric power construction and its intelligent welding system. Background Technique

[0002] In the construction of electric power projects, MPP (modified polypropylene) electric power pipes are widely used in the protection and laying of electric power cables due to their excellent insulation performance, corrosion resistance, and relatively high mechanical strength. Especially in the fields of urban underground power grid transformation, high-voltage transmission line laying, etc., as an important infrastructure material, the connection quality of MPP electric power pipes is directly related to the safety and stability of the entire electric power system.

[0003] However, when the existing devices weld electric power pipes, welding slag, sparks, and welding fumes will be generated. These splashing welding slag and sparks are likely to splash onto the surrounding workers, thus endangering the physical safety of the workers. Moreover, the generated welding fumes are directly discharged to the outside, which will cause pollution to the surrounding environment.

[0004] In view of this, research and improvement are carried out on the existing problems, and a welding device for electric power construction and its intelligent welding system are provided.

In the present invention, water is transported by a water pump through a water delivery pipe to a ring pipe, and a protective water curtain is formed by spraying from nozzle A to block welding sparks, etc., reducing risks. The baffle makes the water flow gather and enhances the blocking effect of the water curtain. Motor B drives the lead screw to make the grinding block fit the weld seam. Motor A is adjusted to rotate the pipe fitting to achieve all-round grinding. At the same time, compressed air flips the baffle to guide the water flow to cool down, wash away debris, and reduce friction. The pipe fitting is placed in the mounting seat, cylinder B drives the clamping plate to clamp, the electric push rod makes the pipe fitting centered, and motor A drives the pipe fitting to rotate to achieve automatic welding, improving quality and efficiency.

[0014] Preferably: Multiple spray nozzles B are installed on the inner wall of the annular pipe, and the spray nozzles B are set to be flat.

[0015] An intelligent welding system for electric power construction, and its welding system includes the following steps: S1: Place the pipe fitting to be welded on the mounting seat. Drive the clamping plate to clamp the pipe fitting from multiple directions through the cylinder B, and then drive the mounting seat to move towards each other by the electric push rod to achieve the centering of the pipe fitting; S2: After completing the fixing and centering of the pipe fitting, start the motor A. The gear at its output end meshes with the toothed ring, driving the toothed ring to rotate around the mounting seat, causing the clamped pipe fitting to rotate synchronously, and using the welding head to uniformly weld the circumference of the pipe fitting; S3: Synchronously start the water pump, transport the water in the water tank to the annular pipe through the water delivery pipe, form a protective water curtain around the welding area through nozzle A, the water flows through the baffle for diversion to form a continuous water curtain curtain, and the water received by the water curtain flows back to the water tank through the water receiving tray; S4: After the welding process is completed, start motor B to drive the lead screw, drive the support rod to make the grinding block fit the weld seam, realize the rotary grinding of the pipe fitting, the movement of the support rod drives the cross bar to compress the gas storage pipe, and send the compressed air to the sleeve through the air delivery pipe, drive the pressure rod to drive the baffle to rotate, and guide the water flow of nozzle A to the weld seam.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By starting the water pump inside the water tank, the present invention transports the water in the water tank to the annular pipe through the water delivery pipe. After the water enters the annular pipe, under the action of water pressure, it sprays out from nozzle A at a high speed. The sprayed water flows towards the periphery of the welding area to form a protective water curtain. The water curtain can surround the welding head and the pipe fitting inside it, thereby effectively blocking the high-temperature sparks and spatter generated during welding, reducing the risk of fire caused by sparks or scalding operators, and providing a reliable guarantee for construction safety. At the same time, the water flow sprayed out from nozzle A above the annular pipe slides along the inner surface of the baffle. The baffle forces the water flow sprayed out from the nozzle to impact its inner surface, and the water flow will flow downward along the inner wall of the baffle and finally spray out from the lower edge of the baffle, making the water flow guide and gather together to form a more concentrated, thicker and more continuous water curtain curtain, enhancing the effect of the water curtain as a physical barrier, and thus being able to more effectively block welding spatter and strong arc radiation.

[0017] 2. By starting motor B to drive the lead screw to rotate, the present invention drives two groups of symmetric support rods to move towards each other along the slide rail, so that the grinding block accurately fits the weld seam of the pipe fitting. The operator manually adjusts the rotation speed of motor A to make the pipe fitting rotate at a high speed in the clamped state, and cooperates with the fixed grinding block to realize all-round weld grinding and improve the welding quality. In addition, when the support rod moves towards the pipe fitting, it drives the cross bar to slide in the gas storage pipe to compress the air. The compressed air reaches the sleeve through the air delivery pipe to increase the air pressure. The pressure rod moves downward overcoming the spring resistance, and the elastic piece deforms to drive the baffle to rotate around the fulcrum. After the baffle flips, it guides the water flow of nozzle A on the annular pipe to flow along its inner wall and spray to the weld seam of the pipe fitting, playing a role in cooling, avoiding secondary oxidation or hardening layer on the surface of the weld seam due to overheating, and at the same time, the formed stable scouring force can scour the metal debris generated by grinding, and the water flow as a lubricant can reduce the frictional resistance between the grinding block and the surface of the pipe fitting, reducing the wear rate of the grinding block.

[0018] 3. In the present invention, the pipe fitting is placed in the mounting seat, and the air cylinder B is started. The output end thereof drives the clamping plate to tighten towards the outer wall of the pipe fitting. Multiple groups of clamping plates apply clamping forces to the pipe fitting from different directions to achieve stable clamping of the pipe fitting. Moreover, the electric push rod drives the two mounting seats to move towards each other, accurately aligning the two pipe fittings to be welded, thereby effectively eliminating the welding deviation caused by the misalignment or shaking of the pipe fittings, avoiding the reduction of the welding quality due to the displacement of the pipe fittings during the welding process. The motor A drives the gear to mesh with the gear ring, and the gear ring rotates around the mounting seat. The rotation of the gear ring drives the clamped pipe fitting to rotate synchronously, enabling the welding head to uniformly weld the circumference of the pipe fitting, realizing automatic rotational welding, reducing manual operation, improving the welding efficiency, ensuring the uniformity and consistency of the weld seam, and effectively enhancing the overall quality and stability of the pipe fitting welding.

[0021] 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 detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed 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 fall within the scope of protection of the present invention.

[0022] Referring to Figures 1 to 8 as shown, the present invention provides a welding device for electric power construction and its intelligent welding system, including a platform 1. Above the platform 1, there is a welding mechanism 2 for welding pipe fittings, and on the surface of the platform 1, there is a fixing mechanism 3 for clamping pipe fittings; Above the platform 1, there is a water curtain mechanism 4. The water curtain mechanism 4 includes a water tank 41 installed at the bottom end of the platform 1. At the top end of the platform 1, there is a water receiving tray 42. On both sides of the water receiving tray 42, there are connecting rods 43 welded. At one end of the connecting rod 43, there is an annular pipe 44 welded. On one side of the annular pipe 44, there are multiple groups of nozzles A45 installed. A water delivery pipe 47 is connected and communicated between the water tank 41 and the annular pipe 44; On the surface of the annular pipe 44, there are two groups of elastic sheets 7 welded. At one end of the two groups of elastic sheets 7, there is a baffle 8 installed; It should be noted that when the welding operation starts, the water pump inside the water tank 41 is started, and the water in the water tank 41 is conveyed to the annular pipe 44 through the water delivery pipe 47 by the water pump. After the water enters the annular pipe 44, under the action of water pressure, it sprays out from the nozzles A45 at a high speed. The sprayed water flows towards the periphery of the welding area, forming a protective water curtain. The water curtain can surround the welding head 23 and the pipe fittings inside it, thereby effectively blocking the high-temperature sparks and spatter generated by welding, reducing the risk of fire caused by sparks or scalding operators, and providing reliable guarantee for construction safety; At the same time, the water flow sprayed out from the nozzles A45 above the annular pipe 44 slides along the inner surface of the baffle 8. The baffle 8 forces the water flow sprayed out by the nozzles to impact its inner surface. Since the elastic deformation threshold of the elastic sheet 7 is greater than the impact force of the water flow, when the water flow impacts the inner wall of the baffle 8, the baffle 8 will not be flipped. Therefore, the water flow will flow downward along the inner wall of the baffle 8 and finally spray out from the lower edge of the baffle 8, making the water flow guide and gather together to form a more concentrated, thicker, and more continuous water curtain, enhancing the effect of the water curtain as a physical barrier, and thus being able to more effectively block welding spatter and strong arc light radiation; In addition, after the water curtain receives the sparks and heat, it will fall into the water receiving tray 42 at the top end of the platform 1. The water collected by the water receiving tray 42 flows back to the water tank 41 through the water trough opened at the top end of the platform 1 and the through hole communicating with the water tank 41, realizing the recycling of water resources.

[0023] At the top of platform 1, there is a grinding mechanism 5 for grinding pipe fittings. The grinding mechanism 5 includes a slide rail 51 installed at the top of platform 1. Two sets of symmetric support rods 54 slide inside the slide rail 51, and a grinding block 55 is installed at one end of the support rod 54. On one side of the baffle 8, there is an adjusting mechanism 6 for adjusting the angle of the baffle 8. The adjusting mechanism 6 includes a U-shaped frame 61 installed at the top of platform 1. A sleeve 64 is installed through the inside of the U-shaped frame 61. A pressure rod 65 slides inside the sleeve 64. Above the slide rail 51, there is an air storage pipe 62. Two cross bars 63 slide inside the air storage pipe 62. One end of the cross bar 63 is fixedly connected to one side of the grinding block 55. A gas transmission pipe 67 is connected between the air storage pipe 62 and the sleeve 64.

[0024] It should be noted that after the welding process is completed, start motor B53 to drive the lead screw 52 to rotate. The lead screw 52 adopts a double-thread design. When it rotates, it drives two sets of symmetric support rods 54 to move towards each other along the slide rail 51, so that the support rods 54 drive the grinding block 55 to accurately fit the weld of the pipe fitting. And the operator manually adjusts the rotation speed of motor A36 to increase the rotation speed of the pipe fitting, so that the pipe fitting rotates at a high speed in the clamped state, and cooperates with the grinding block 55 at a fixed position to achieve all-round weld grinding, improving the welding quality of the pipe fitting. At the same time, when the support rod 54 moves towards the pipe fitting, the connected cross bar 63 slides synchronously inside the air storage pipe 62, compressing the air inside the air storage pipe 62. The compressed air is transported to the inside of the sleeve 64 through the gas transmission pipe 67, increasing the air pressure inside the sleeve 64. Under the action of the air pressure, the pressure rod 65 can not only overcome the resistance of the spring 66 and move downward, but also the downward pressure generated by the pressure rod 65 is greater than the elastic deformation threshold of the elastic piece 7 and the impact force of the water flow. Therefore, the elastic piece 7 connected to the bottom end of the pressure rod 65 and the baffle 8 can undergo elastic deformation. Thus, the pressure rod 65 can drive the baffle 8 to rotate a certain angle around the fulcrum. When the baffle 8 flips, the water flow sprayed by the nozzle A45 on the annular pipe 44 flows along the inner wall of the baffle 8, so that the water flow sprays onto the weld of the pipe fitting along the inclined surface of the baffle 8. Thereby, the water flow is used to cool the grinding area, avoiding secondary oxidation or hardening layer on the surface of the weld due to overheating. And the baffle 8 directs the water flow to form a stable scouring force, so that the metal chips generated during the grinding process can be washed away, avoiding the chips from embedding into the surface of the pipe fitting and affecting the quality. At the same time, the water flow as a lubricant can reduce the frictional resistance between the grinding block 55 and the surface of the pipe fitting, making the grinding process smoother and reducing the wear rate of the grinding block 55.

[0025] As described above, the water pump in the water tank 41 sends water through the water delivery pipe 47 to the annular pipe 44, and sprays out from the nozzle A45 to form a protective water curtain, surrounding the welding head 23 and the pipe fittings, blocking the spark splashes. The water curtain flows along the inner wall of the baffle 8 and then forms a more concentrated water curtain, enhancing the blocking effect. After welding is completed, the motor B53 is started to drive the lead screw 52 to rotate, driving the support rod 54 to move towards each other along the slide rail 51, so that the grinding block 55 fits the weld of the pipe fitting. The operator adjusts the motor A36 to increase the rotation speed of the pipe fitting, and cooperates with the grinding block 55 to achieve all-round grinding. At the same time, the movement of the support rod 54 drives the cross bar 63 to compress the air in the air storage pipe 62. The compressed air reaches the sleeve 64 through the air delivery pipe 67, causing the pressure rod 65 to move downward against the resistance of the spring 66. The deformation of the elastic piece 7 drives the baffle 8 to turn a certain angle, guiding the water flow of the nozzle A45 to the weld to cool down and wash away the metal debris. The water flow can also act as a lubricant to reduce the frictional resistance.

[0026] Refer to Figures 1 to 2 As shown, the welding mechanism 2 includes a mounting frame 21 installed at the top end of the platform 1. A cylinder A22 is installed at the top end of the mounting frame 21, and a welding head 23 is installed at the output end of the cylinder A22.

[0027] Refer to Figures 2 to 3 As shown, the fixing mechanism 3 includes an electric push rod 31 installed at the top end of the platform 1. A mounting seat 32 slides on the surface of the electric push rod 31. A gear ring 33 rotates on the surface of the mounting seat 32. A plurality of groups of cylinders B34 are installed inside the gear ring 33, and a clamping plate 35 is installed at the output end of the cylinder B34.

[0028] Refer to Figure 3 As shown, a motor A36 is installed on one side of the mounting seat 32, and a spring 66 meshed with the gear 37 is installed at the output end of the motor A36.

[0029] It should be noted that when welding the pipe fitting, first, place the pipe fitting in the mounting seat 32, start the cylinder B34, and its output end drives the clamping plate 35 to tighten towards the outer wall of the pipe fitting. The plurality of groups of clamping plates 35 apply clamping forces to the pipe fitting from different directions to achieve stable clamping of the pipe fitting. After clamping, the electric push rod 31 drives the two mounting seats 32 to move towards each other, accurately aligning the two pipe fittings to be welded, thereby effectively eliminating the welding deviation caused by the misalignment or shaking of the pipe fitting, ensuring the accuracy of the welding position, and avoiding reducing the welding quality due to the displacement of the pipe fitting during the welding process. After fixing and alignment are completed, the motor A36 is started, and the gear 37 at its output end meshes with the gear ring 33, driving the gear ring 33 to rotate around the mounting seat 32. The rotation of the gear ring 33 drives the clamped pipe fitting to rotate synchronously, enabling the welding head 23 to uniformly weld the circumference of the pipe fitting, realizing automatic rotational welding, reducing manual operation, improving the welding efficiency, and ensuring the uniformity and consistency of the weld, effectively improving the overall quality and stability of the pipe fitting welding.

[0030] Refer toFigure 4 As shown, the baffle 8 is set to a semi-circular shape and is made of a high-temperature resistant and high-strength metal material, enabling it to maintain structural integrity and performance stability under complex working conditions of long-term high temperature, spark impact, and water flow erosion, and avoiding protection failure caused by material deformation or damage.

[0031] Refer to Figure 2 As shown, a water tank is provided at the top of the platform 1, and through holes communicating with the water tank 41 are penetrated on the surface of the water tank, facilitating the collection of water flow and realizing recycling.

[0032] Refer to Figure 8 As shown, the grinding mechanism 5 further includes a lead screw 52 rotating inside the slide rail 51, and a motor B53 is installed at one end of the lead screw 52.

[0033] Refer to Figures 6 to 7 As shown, a spring 66 is provided inside the sleeve 64, and the spring 66 is sleeved on the outer wall of the pressure rod 65. After the welding and grinding process is completed, the air pressure in the air storage pipe 62 drops, and the spring 66 releases the stored elastic potential energy, driving the pressure rod 65 to reset upward, driving the baffle 8 to return to its initial position, preparing for the next adjustment, and realizing the cyclic use of the mechanism.

[0034] Refer to Figure 4 As shown, multiple groups of nozzles B46 are installed on the inner wall of the annular pipe 44. The nozzles B46 are set to be flat-shaped, and the flat-shaped nozzle structure can spray the water flow in a fan-shaped wide-angle form, forming a large-area, thin and uniform water curtain. The multiple groups of nozzles B46 are evenly distributed along the inner wall of the annular pipe 44 to protect the welding and grinding areas from all directions, prevent it from splashing everywhere, and reduce potential safety hazards.

[0035] An intelligent welding system for electric power construction, and its welding system includes the following steps: S1: Place the pipe fittings to be welded on the mounting seat 32, drive the clamping plate 35 to clamp the pipe fittings from multiple directions through the cylinder B34, and then drive the mounting seat 32 to move towards each other by the electric push rod 31 to achieve pipe fitting alignment; S2: After the pipe fittings are fixed and aligned, start the motor A36. The gear 37 at its output end meshes with the gear ring 33, driving the gear ring 33 to rotate around the mounting seat 32, making the clamped pipe fittings rotate synchronously, and uniformly welding the circumference of the pipe fittings by using the welding head 23; S3: Synchronously start the water pump, transport the water in the water tank 41 to the annular pipe 44 through the water delivery pipe 47, form a protective water curtain around the welding area through the nozzles A45, the water flow forms a continuous water curtain after being guided by the baffle 8, and the water received by the water curtain flows back to the water tank 41 through the water receiving tray 42; S4: After the welding process is completed, start the motor B53 to drive the lead screw 52, drive the support rod 54 to make the grinding block 55 fit the weld seam, realize the rotary grinding of the pipe fitting, the movement of the support rod 54 drives the cross bar 63 to compress the air storage pipe 62, and send the compressed air to the sleeve 64 through the air delivery pipe 67, drive the pressure rod 65 to drive the baffle 8 to rotate, and guide the water flow of the spray head A45 to the weld seam.

[0036] Working principle: When in use, first, place the pipe fitting in the mounting seat 32, start the cylinder B34, and its output end drives the clamping plate 35 to tighten towards the outer wall of the pipe fitting, and apply clamping force to the pipe fitting from different directions through multiple groups of clamping plates 35 to realize the stable clamping of the pipe fitting; after clamping, drive the two mounting seats 32 to move towards each other through the electric push rod 31, and accurately align the two pipe fittings to be welded, so as to effectively eliminate the welding deviation caused by the misalignment or shaking of the pipe fittings, ensure the accuracy of the welding position, and avoid reducing the welding quality due to the displacement of the pipe fittings during the welding process; after completing the fixation and alignment, start the motor A36, the gear 37 at its output end meshes with the gear ring 33, drive the gear ring 33 to rotate around the mounting seat 32, and the rotation of the gear ring 33 drives the clamped pipe fitting to rotate synchronously, so that the welding head 23 can uniformly weld the circumference of the pipe fitting, realize automatic rotary welding, reduce manual operation, improve the welding efficiency, and ensure the uniformity and consistency of the weld seam, effectively improving the overall quality and stability of the pipe fitting welding; When the welding operation starts, start the water pump inside the water tank 41, and send the water in the water tank 41 to the annular pipe 44 through the water delivery pipe 47 through the water pump. After the water enters the annular pipe 44, under the action of water pressure, it sprays out from the spray head A45 at a high speed, and the sprayed water flow goes to the periphery of the welding area to form a protective water curtain. The water curtain can surround the welding head 23 and the pipe fitting inside it, so as to effectively block the high-temperature sparks and spatter generated by welding, reduce the risk of fire caused by sparks or scalding operators, and provide a reliable guarantee for construction safety; At the same time, the water flow sprayed out by the spray head A45 above the annular pipe 44 slides along the inner surface of the baffle 8, and the baffle 8 forces the water flow sprayed out by the spray head to impact its inner surface. Since the elastic deformation threshold of the elastic piece 7 is greater than the impact force of the water flow, when the water flow impacts the inner wall of the baffle 8, the baffle 8 will not be turned over. Therefore, the water flow will flow downward along the inner wall of the baffle 8 and finally spray out from the lower edge of the baffle 8, so that the water flow is guided and gathered together to form a more concentrated, thicker and more continuous water curtain, enhancing the effect of the water curtain as a physical barrier, so as to more effectively block the welding spatter and strong arc radiation; In addition, after the water curtain receives the sparks and heat, it will fall into the water receiving tray 42 at the top of the platform 1. The water collected by the water receiving tray 42 returns to the water tank 41 through the water groove opened at the top of the platform 1 and the through hole connecting the water tank 41, realizing the recycling of water resources; After the welding process is completed, start the motor B53 to drive the screw rod 52 to rotate. The screw rod 52 is designed with a double-thread, and when it rotates, it drives two sets of symmetric support rods 54 to move towards each other along the slide rail 51, so that the support rods 54 drive the grinding block 55 to accurately fit the weld of the pipe fitting. And the operator manually adjusts the rotation speed of the motor A36 to increase the rotation speed of the pipe fitting, so that the pipe fitting rotates at a high speed in the clamped state, and cooperates with the grinding block 55 at a fixed position to achieve all-round weld grinding, improving the welding quality of the pipe fitting; At the same time, when the support rod 54 moves towards the pipe fitting, the cross bar 63 connected to it slides synchronously in the air storage pipe 62, compressing the air in the air storage pipe 62. The compressed air is conveyed through the air delivery pipe 67 into the sleeve 64, increasing the air pressure in the sleeve 64. Under the action of the air pressure, the pressure rod 65 can not only move downward overcoming the resistance of the spring 66, but also the downward pressure generated by the pressure rod 65 is greater than the elastic deformation threshold of the elastic piece 7 and the impact force of the water flow. Thus, the elastic piece 7 connected to the bottom end of the pressure rod 65 and the baffle 8 can undergo elastic deformation. Therefore, the pressure rod 65 can drive the baffle 8 to rotate a certain angle around the fulcrum. When the baffle 8 flips, the water flow sprayed from the nozzle A45 on the annular pipe 44 is guided along the inner wall of the baffle 8, so that the water flow is sprayed onto the weld of the pipe fitting along the inclined surface of the baffle 8. Thus, the water flow is used to cool the grinding area, avoiding secondary oxidation or hardening layer on the weld surface due to overheating. And the baffle 8 directs the water flow to form a stable scouring force, which can wash away the metal debris generated during the grinding process, preventing the debris from embedding into the surface of the pipe fitting and affecting the quality; At the same time, the water flow as a lubricant can reduce the frictional resistance between the grinding block 55 and the surface of the pipe fitting, making the grinding process smoother and reducing the wear rate of the grinding block 55.
