Description

Technical Field

[0001] The present invention relates to the technical field of welding, and specifically to a welding device for water conservancy construction pipelines. Background Technique

[0002] Water conservancy projects are crucial for controlling and allocating surface water and groundwater in nature, and can achieve the purpose of eliminating disasters and bringing benefits, meeting the needs of people's lives and production for water resources. In the construction of water conservancy projects, a large number of pipelines are often required to achieve functions such as water transportation and distribution. Due to limitations in equipment technology and space during the production and manufacturing of pipelines, their lengths often cannot meet the actual requirements of water conservancy construction. Therefore, welding equipment is needed to weld the pipelines to extend their lengths and meet the requirements of water conservancy projects.

[0003] In the prior art, the construction areas of water conservancy construction are usually in areas by rivers or with high groundwater levels. In such areas, pipelines are prone to being affected by moisture. The moisture on the surface of the affected pipelines will quickly evaporate into water vapor under the action of the high temperature of the electric arc. After these water vapors enter the molten pool, if they cannot escape in time, pores will be formed in the weld. The existence of pores will weaken the effective cross-sectional area of the weld, reduce the strength and tightness of the weld, and cause problems such as easy leakage when the weld bears pressure. Therefore, welding on the surface of moisture-affected pipelines will affect the welding quality.

[0004] Therefore, we propose a welding device for water conservancy construction pipelines to facilitate solving the problems raised above. Summary of the Invention

[0009] Preferably, the outer surfaces of the two bag nets are fixedly connected with a feeding port, and the feeding port is used to add desiccant filling material to the interior of the bag net.

[0010] Preferably, the support assembly includes a support base plate, four support columns are fixedly connected to the top of the support base plate, a support slide rod is fixedly connected between the outer surfaces of each two support columns, and a mounting plate is fixedly connected between two opposing support columns.

[0012] Preferably, an adjusting rod is fixedly connected to the outer side of the mounting block, and the two limiting arcs are fixedly mounted on one side of the two arc-shaped positioning plates respectively, and the two limiting arcs are symmetrically arranged.

[0013] Preferably, a positioning assembly is provided on the top of the supporting base plate, and the positioning assembly includes a hydraulic cylinder, the top end of the hydraulic cylinder is fixedly connected to a connecting plate, both ends of the connecting plate are fixedly connected to connecting rods, both ends of the two connecting rods are fixedly connected to fixed blocks, a movable hole is provided on the outer surface of each fixed block, a movable shaft is movably connected to the inner wall of each movable hole, and an adjusting rod is fixedly connected between the two ends of each movable shaft.

[0014] Preferably, the middle of each adjusting rod is rotatably connected to a supporting shaft, and each supporting shaft is fixedly mounted on the outer surface of each supporting column.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. During use, by placing a desiccant filler inside the scoop net, when the scoop net is in close contact with the pipe body, the desiccant filler will absorb the moist water at the joint of the pipe body. The desiccant filler used is silica gel desiccant. When the silica gel desiccant is in close contact with the surface of the pipe body and comes into contact with the moist water, the moist water molecules will move to the surface of the silica gel. It does not chemically react with the material of the pipe body and the welding material used in the welding process, and will not have an adverse impact on the pipe and welding quality, solving the problem that the welding quality will be affected when welding the surface of the existing water conservancy construction pipe after it gets damp. The scoop net is a mesh structure with strong water absorption, which has the advantage of assisting in water absorption. After the surface of the pipe body is dried, the welding torch body is then moved to the joint of the two pipe bodies to weld the dry joint, avoiding the occurrence of cracks, bubbles, etc. after welding.

[0018] 2. During use, by starting the forward and reverse motor, the bidirectional lead screw rotates, and then the two arc-shaped positioning plates can be combined into a circular ring, which is wrapped around the joint of the two pipe bodies to achieve drying treatment. Next, drive the bidirectional lead screw to rotate in the reverse direction again to make the two arc-shaped positioning plates unfold. Then, start the hydraulic cylinder to make it extend. During the extension process, the two limiting arcs will be pushed towards the pipe joint. Then, drive the bidirectional lead screw to rotate again to make the two arc-shaped positioning plates approach and combine again until the two limiting arcs form a circular ring track. By sliding the movable clamp outside the limiting arc in advance, the two limiting arcs can form a circular movable track of the movable clamp when forming a circular ring. During welding, power on and turn on the welding torch body, and by holding the adjusting rod, the movable clamp can be moved, so that the welding torch body does not shake during the welding of the two pipe bodies, ensuring the accuracy of the welding position.

[0019] 3. During use, by starting the hydraulic cylinder, the adjusting rod rotates around the supporting rotating shaft, the fixed block drives the movable shaft to be lifted obliquely upward, and one end connected to the fixed shaft is pressed obliquely downward. The two symmetric positioning clamping plates in the same group form a circular whole, and the pipe body will be tightly positioned under the clamping of the positioning clamping plates. After the two pipe bodies are clamped and positioned, their two ends are in an aligned state, accurately clamping and positioning the two pipe bodies at one time, avoiding the situation of frequently adjusting the position of the pipe body during the welding process. During water conservancy construction, there is no need to spend a lot of time repeatedly aligning the pipes, thus saving time and improving the efficiency of the welding work. And when drying and welding operations are carried out on the surface of the pipe body, there is no need to change the clamping position, improving the stability of the pipe body during welding. Since the position of the pipe body is fixed, the stability of the arc during welding is good, and the shape and size of the molten pool are also relatively stable, which is beneficial to obtaining a uniform and beautiful weld formation.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0031] Embodiment 1: Refer to Figures 1-8 As shown, the present invention provides a technical solution: a welding device for a water conservancy construction pipeline, including a support assembly 1, a drying assembly 3, and two pipeline bodies 5. A welding assembly 4 is arranged on the outer surface of the drying assembly 3. The drying assembly 3 includes two arc-shaped positioning plates 303. Sieve nets 306 are pasted on the opposite inner walls of the two arc-shaped positioning plates 303. Desiccant fillers 307 are placed inside the two sieve nets 306, and the material of the desiccant fillers 307 is silica gel desiccant, which is used to remove the moisture on the surface of the water conservancy construction pipeline; the welding assembly 4 includes two limiting arcs 401. A movable clamp 402 is movably connected to the outer surface of the two limiting arcs 401. A mounting block 403 is fixedly connected to the outer surface of the movable clamp 402. A welding torch body 404 is arranged inside the mounting block 403. The drying assembly 3 further includes a moving seat 302. A multi-stage electric push rod 301 is arranged on one side of the moving seat 302. Support sliding frames 304 are fixedly connected to the outer surfaces on both sides of the moving seat 302. A limiting rod 305 is fixedly connected between the opposite inner walls of the moving seat 302. One end of the limiting rod 305 slides through the two arc-shaped positioning plates 303 to the outside. A positive and negative motor 309 is arranged on one side of the moving seat 302 through a support plate. An output shaft of the positive and negative motor 309 is fixedly connected to a bidirectional lead screw 310. One end of the bidirectional lead screw 310 threadedly penetrates through the two arc-shaped positioning plates 303 to the outside, and both ends of the bidirectional lead screw 310 rotate on the opposite inner walls of the moving seat 302. Feeding ports 308 are fixedly communicated with the outer surfaces of the two sieve nets 306, and the feeding ports 308 are used to supplement the desiccant fillers 307 into the sieve nets 306. A positioning assembly 2 is arranged on the top of the support bottom plate 101.

[0032] In this embodiment, during use, the positioning component 2 is used to simultaneously clamp and position the two pipe bodies 5, facilitating high-quality welding between the two pipe bodies 5. During the positioning process, the two arc-shaped positioning plates 303 drive the two limiting arcs 401 to be in an unfolded state, and the pipe body 5 is in the middle position. The bidirectional lead screw 310 is driven to rotate by the forward and reverse motor 309. Since the bottoms of the two arc-shaped positioning plates 303 slide outside the limiting rod 305, the rotation of the bidirectional lead screw 310 can achieve the clamping of the pipe body 5 by the two arc-shaped positioning plates 303. By placing the desiccant filler 307 inside the mesh bag 306, when the mesh bag 306 is in close contact with the pipe body 5, the desiccant filler 307 will absorb the moisture at the joint of the pipe body 5. The desiccant filler 307 uses silica gel desiccant. The main component of the silica gel desiccant is silicon dioxide, and its internal structure is a very fine pore network structure. These pores have strong adsorption ability. When the silica gel desiccant is in close contact with the surface of the pipe body 5 and comes into contact with the moist water, the moist water molecules will move to the surface of the silica gel and be adsorbed in these pores. Moreover, the silica gel desiccant has stable chemical properties and does not react chemically with the material of the pipe body 5 and the welding materials used during the welding process, and will not have an adverse impact on the pipe and the welding quality, solving the problem that the welding quality will be affected when the surface of the existing water conservancy construction pipe is affected by moisture before welding. In addition, by opening the lid of the feeding port 308, the silica gel desiccant can be fed into the mesh bag 306 through the feeding port 308. The mesh bag 306 is a mesh structure with strong water absorption, which has the advantage of assisting in water absorption. After the surface of the pipe body 5 is dried, the welding torch body 404 is then moved to the joint of the two pipe bodies 5, so as to weld the dry joint, avoiding the occurrence of cracks, bubbles, etc. after welding.

[0033] Embodiment Two: Figures 1-8As shown, the drying component 3 further includes a moving seat 302. One side of the moving seat 302 is provided with a multi-stage electric push rod 301. Both outer surfaces of the moving seat 302 are fixedly connected with support sliding frames 304. A limiting rod 305 is fixedly connected between the opposite inner walls of the moving seat 302. One end of the limiting rod 305 slides through the two arc-shaped positioning plates 303 to the outside. A forward and reverse motor 309 is arranged on one side of the moving seat 302 through a support plate. The output shaft of the forward and reverse motor 309 is fixedly connected with a bidirectional lead screw 310. One end of the bidirectional lead screw 310 threadedly penetrates through the two arc-shaped positioning plates 303 to the outside, and both ends of the bidirectional lead screw 310 rotate on the opposite inner walls of the moving seat 302 respectively. The welding component 4 includes two limiting arcs 401. The outer surfaces of the two limiting arcs 401 are movably connected with a movable clamp 402. The outer surface of the movable clamp 402 is fixedly connected with a mounting block 403. A welding torch body 404 is arranged inside the mounting block 403. The support component 1 includes a support bottom plate 101. Four support columns 102 are fixedly connected to the top of the support bottom plate 101. Support sliding rods 104 are fixedly connected between the outer surfaces of every two support columns 102. A mounting plate 103 is fixedly connected between the opposite sides of two of the support columns 102. One end of the multi-stage electric push rod 301 is fixedly connected to the outer surface of the mounting plate 103. The two support sliding frames 304 are slidably sleeved on the outside of the two support sliding rods 104. An adjusting pull rod 405 is fixedly connected to the outside of the mounting block 403. The two limiting arcs 401 are respectively fixedly installed on one side of the two arc-shaped positioning plates 303, and the two limiting arcs 401 are symmetrically arranged.

[0034] In this embodiment, during use, four conical feet for positioning are installed at the bottom of the support base plate 101. Then, when the support base plate 101 is placed on a wet ground, it will not cause slipping. Moreover, the support base plate 101 is elevated to prevent water from flooding the components above the support base plate 101. The support column 102 has a firm and stable structure and is used to support the pipeline main body 5 and the entire equipment. Additionally, by starting the hydraulic cylinder 201 and making it contract until the two arc-shaped positioning plates 303 are located at the joint of the two pipeline main bodies 5, then by starting the forward and reverse motor 309 and making its output shaft rotate, the bidirectional lead screw 310 is driven to rotate, and thus the two arc-shaped positioning plates 303 can be combined into a circular ring to wrap the joint of the two pipeline main bodies 5 for drying treatment. Next, drive the bidirectional lead screw 310 to rotate in the reverse direction again to make the two arc-shaped positioning plates 303 unfold. Then, start the hydraulic cylinder 201 to make it extend. During the extension process, the two limit arcs 401 will be pushed towards the pipeline joint. Then, drive the bidirectional lead screw 310 to rotate again to make the two arc-shaped positioning plates 303 approach and combine again until the two limit arcs 401 form a circular ring track. By pre-sleeving the movable clamp 402 on the outside of the limit arc 401 and sliding it, the two limit arcs 401 can form a circular movable track for the movable clamp 402 when forming a circular ring. The welding torch body 404 is installed inside the mounting block 403. During welding, make the welding torch body 404 energized and turned on, and hold the adjusting pull rod 405 to be able to move the movable clamp 402, so that the welding torch body 404 does not shake during the welding process of the two pipeline main bodies 5, ensuring the accuracy of the welding position.

[0035] Embodiment 3: Figures 1-8 As shown in the figure, the support assembly 1 includes a support base plate 101. Four support columns 102 are fixedly connected to the top of the support base plate 101. A positioning assembly 2 is arranged on the top of the support base plate 101. The positioning assembly 2 includes a hydraulic cylinder 201. The top end of the hydraulic cylinder 201 is fixedly connected to a connecting plate 202. Connecting rods 203 are fixedly connected to both ends of the connecting plate 202. Fixed blocks 204 are fixedly connected to both ends of the two connecting rods 203. An activity hole 205 is formed on the outer surface of each fixed block 204. An activity shaft 206 is movably connected to the inner wall of each activity hole 205. A regulating rod 207 is fixedly connected between both ends of each activity shaft 206. A support rotating shaft 208 is rotatably connected to the middle of each regulating rod 207. Each support rotating shaft 208 is fixedly installed on the outer surface of each support column 102. A fixed shaft 209 is rotatably connected to the top end of each regulating rod 207. A positioning clamping plate 210 is fixedly connected to the outer surface of each fixed shaft 209. Every two positioning clamping plates 210 are symmetrically arranged, and the positioning clamping plate 210 is used for clamping the pipeline main body 5.

[0036] In this embodiment, during use, the two pipeline bodies 5 to be welded are respectively inserted between two groups of positioning clamping plates 210, so that the end faces of the two pipeline bodies 5 are aligned and closely attached. At this time, by starting the hydraulic cylinder 201 to make it extend, the connecting plate 202 is driven to rise. At the same time, the connecting rods 203 at both ends of the connecting plate 202 move upward simultaneously. The adjusting rod 207 rotates around the supporting rotating shaft 208, so that the fixing block 204 drives the movable shaft 206 to be lifted obliquely upward. Using the lever principle, the end of the adjusting rod 207 connected to the fixed shaft 209 will be pressed obliquely downward. Two symmetric positioning clamping plates 210 in the same group form a circular whole, and the pipeline body 5 will be tightly positioned under the clamping of the positioning clamping plates 210. After the two pipeline bodies 5 are clamped and positioned, their two ends are in an aligned state, and the two pipeline bodies 5 are accurately clamped and positioned at one time, avoiding the situation of frequently adjusting the position of the pipeline body 5 during the welding process. During water conservancy construction, there is no need to spend a lot of time repeatedly aligning the pipelines, thus saving time and improving the efficiency of the welding work. And when drying and welding operations are carried out on the surface of the pipeline body 5, there is no need to change the clamping position, so that the stability of the pipeline body 5 during welding is improved. Since the position of the pipeline body 5 is fixed, the stability of the arc during welding is good, and the shape and size of the molten pool are also relatively stable, which is conducive to obtaining a uniform and beautiful weld formation.

[0037] The method of use and working principle of this device: When in use, four conical feet for positioning are installed at the bottom of the support base 101, so when the support base 101 is placed on a wet ground, it will not cause slipping. Moreover, the support base 101 is raised to prevent water from submerging the components above the support base 101. The structure of the support column 102 is firm and stable, and is used to support the pipe body 5 and the equipment as a whole. When in use, the two pipe bodies 5 to be welded are respectively inserted between the two sets of positioning clamps 210 so that the end faces of the two pipe bodies 5 are aligned and close together. At this time, by starting the hydraulic cylinder 201, it is extended, thereby driving the connecting plate 202 to rise. At the same time, the connecting rods 203 at both ends of the connecting plate 202 move upward at the same time. The adjusting rod 207 rotates around the supporting shaft 208, so that the fixed block 204 drives the movable shaft 206 to be lifted obliquely upward. By utilizing the principle of leverage, the adjusting rod 207, which is connected to the end of the fixed shaft 209, is pressed obliquely downward. The two symmetrical positioning clamps 210 of the same group form a circular whole. The pipe body 5 is tightly positioned under the clamping of the positioning clamps 210. After the two pipe bodies 5 are clamped and positioned, their two ends are in an aligned state. The two pipe bodies 5 are accurately clamped and positioned at one time, avoiding the situation of frequent adjustment of the position of the pipe bodies 5 during welding. During water conservancy construction, there is no need to spend a lot of time to repeatedly align the pipes, and there is no need to change the clamps when the surface of the pipe body 5 is dried and welded. The held position improves the stability of the pipe body 5 during welding. Since the position of the pipe body 5 is fixed, the arc is stable during welding, and the shape and size of the molten pool are relatively stable. In addition, by starting the hydraulic cylinder 201, it is contracted until the two arc-shaped positioning plates 303 are located at the joint of the two pipe bodies 5, and then by starting the forward and reverse motors 309 to rotate the output shaft, thereby driving the bidirectional screw rod 310 to rotate, and then the two arc-shaped positioning plates 303 can be merged into a circular ring, which is wrapped around the joint of the two pipe bodies 5 to achieve drying treatment. Next, the bidirectional screw rod 310 is driven to rotate in the opposite direction again to expand the two arc-shaped positioning plates 303. After that, the hydraulic cylinder 201 is started again to extend it. During the extension process, the two limiting plates 303 are The positioning arc 401 is pushed toward the pipe joint, and then the bidirectional screw rod 310 is driven to rotate again, so that the two arc-shaped positioning plates 303 are brought together again until the two limiting arcs 401 form a circular track. By pre-sleeving the movable clamp 402 on the outside of the limiting arc 401 and sliding it, the two limiting arcs 401 can form a circular movable track of the movable clamp 402 when forming a circular ring. The welding gun body 404 is installed inside the mounting block 403. When welding, the welding gun body 404 is powered on and turned on. Holding the adjusting rod 405 can move the movable clamp 402, so that the welding gun body 404 does not shake during the welding of the two pipe bodies 5. When in use, the two pipe bodies 5 are clamped and positioned at the same time by using the positioning assembly 2.For facilitating high-quality welding between two pipe bodies 5, during the positioning process, two arc-shaped positioning plates 303 drive two limiting arcs 401 to be in an unfolded state, and the pipe body 5 is in the middle position. The bidirectional lead screw 310 is driven to rotate by the forward and reverse motor 309. Since the bottoms of the two arc-shaped positioning plates 303 slide outside the limiting rod 305, the rotation of the bidirectional lead screw 310 can realize the clamping of the pipe body 5 by the two arc-shaped positioning plates 303. By placing a desiccant filler 307 inside the net pocket 306, when the net pocket 306 is close to the pipe body 5, the desiccant filler 307 will absorb the moist water at the joint of the pipe body 5. The desiccant filler 307 uses silica gel desiccant. The main component of the silica gel desiccant is silicon dioxide, and its internal is a very fine pore network structure. These pores have a strong adsorption capacity. When the silica gel desiccant is close to the surface of the pipe body 5 and contacts with the moist water, the moist water molecules will move to the surface of the silica gel and be adsorbed in these pores. Moreover, the silica gel desiccant has stable chemical properties and does not chemically react with the material of the pipe body 5 and the welding materials used during the welding process, and will not have an adverse impact on the pipe and the welding quality. In addition, by opening the lid of the feeding port 308, the silica gel desiccant can be fed into the net pocket 306 through the feeding port 308. The net pocket 306 is a mesh structure with strong water absorption and has the advantage of assisting in water absorption. After the surface of the pipe body 5 is dried, the welding torch body 404 is then moved to the joint of the two pipe bodies 5 to weld the dry joint.,

Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the hydraulic cylinder 201, the multi-stage electric push rod 301, and the forward and reverse motor 309 will not be explained in detail.,
