Description

Technical Field

[0001] This invention relates to the field of steel plate stud welding technology, specifically to a welding device and construction method for profiled steel plate studs used in the construction of metallurgical plants. Background Technology

[0002] Profiled steel sheets are formed by cold-bending coated or plated steel sheets into a corrugated cross-section along their width using roll forming. When used as roofing or wall panels in industrial plants, profiled steel sheets typically consume approximately 5–11 kg of steel per square meter without insulation requirements. For applications requiring insulation, mineral wool boards, glass wool, or foam plastics can be used as insulation materials. Combining profiled steel sheets with concrete to create composite floor slabs eliminates the need for wooden formwork and can also serve as a load-bearing structure.

[0003] When welding existing profiled steel sheets to steel beams, the profiled steel sheet needs to be placed on top of the steel beam, and a sliding plate is pulled to one side to make the sliding plate slide. The spring is compressed and clamps the profiled steel sheet. Then, the welding studs to be welded to the profiled steel sheet and the steel beam are placed inside the limiting groove. At the same time, two clamping blocks are used to clamp the welding studs between the two clamping blocks. However, when clamping the profiled steel sheet, there will be some dust and small particles on its surface, which reduces the friction between the steel sheet and the clamping plate, thus reducing the clamping effect. Summary of the Invention

[0004] The purpose of this invention is to provide a stud welding device for profiled steel sheet roofing in metallurgical plant construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The top of the bracket is provided with an auxiliary positioning mechanism; the auxiliary positioning mechanism includes a feeding unit and a clamping unit.

[0008] The clamping unit includes an installation platform, a hydraulic cylinder, a clamping plate one, a clamping plate two, a clamping block one, and a clamping block two. The installation platform is fixedly installed on the side of the column, the hydraulic cylinder is installed on the top of the installation platform, the clamping plate one is connected to the output end of the hydraulic cylinder, the clamping plate two is fixedly connected to one side of the clamping plate one, and the clamping block one and the clamping block two are both disposed inside the clamping plate two.

[0009] Preferably, the clamping plate 2 has a cavity 1 and a cavity 2 opened in sequence inside, the clamping block 1 is slidably connected to the inside of cavity 1, and the clamping block 2 is slidably connected to the inside of cavity 2.

[0010] Preferably, a groove is provided on one side of the inner wall of the cavity, and a slider is slidably connected inside the groove. A telescopic spring is fixedly connected to one side of the clamping block. After welding is completed, the hydraulic cylinder is released, and under the action of the telescopic spring's own restoring force, the clamping block will be pushed to reset and slide.

[0011] Preferably, the clamping block one has a connecting pipe inside, and a suction cup is fixedly connected to one side of the clamping block one. A small gap is opened in the center of the suction cup. The interior of the cavity two is connected to the outside through the connecting pipe and the gap in the center of the suction cup. After the air is ejected through the gap in the center of the suction cup, the space inside the cavity one is completely compressed. At this time, the suction cup will firmly adhere to the surface of the profiled steel plate due to the negative pressure.

[0012] Preferably, the interior of the clamping plate two is provided with a ventilation channel, the cavity one and the cavity two are connected through the ventilation channel, a fixed magnetic block is fixedly installed inside the clamping plate two, and a sliding magnetic block is fixedly connected to one side of the interior of the clamping block two, and the fixed magnetic block and the sliding magnetic block attract each other on the side that are close to each other.

[0013] Preferably, one side of the clamping block two has an exhaust hole with a diameter smaller than the width of the clamping block two, so air will be quickly ejected from the exhaust hole, blowing off the dust and small particles attached to the surface of the profiled steel sheet.

[0014] Preferably, the feeding unit includes a support base, a slide rail, a sliding block, a load-bearing plate, a telescopic hose, a strong magnetic block, and a magnetic plate. The support base is fixedly connected to both sides of the bracket, the slide rail is fixedly connected to the top of the support base, the sliding block is slidably connected to the upper surface of the slide rail, the load-bearing plate is fixedly connected to the side of the sliding block, the telescopic hose is fixedly connected to the back of the load-bearing plate, the strong magnetic block is fixedly connected to the end of the telescopic hose away from the load-bearing plate, and the magnetic plate is fixedly connected to the top of the bracket.

[0015] Preferably, the welding device includes a connecting plate, a first cylinder, a lifting platform, a second cylinder, a connecting arm, and a welding head. The connecting plate is fixedly connected to the side of the column, the first cylinder is fixedly installed on the top of the connecting plate, the lifting platform is connected to the output end of the first cylinder, the second cylinder is fixedly installed on the top of the lifting platform, the connecting arm is connected to the output end of the second cylinder, and the welding head is installed on the end of the connecting arm away from the second cylinder.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The profiled steel sheet stud welding device used in the construction of waterproof roofing in this metallurgical plant has a cavity in which a portion of the air inside enters the interior of the connecting pipe. The air is then ejected from the interior of the connecting pipe through the gap in the center of the suction cup. Because the diameter of the gap in the center of the suction cup is much smaller than the diameter of the connecting pipe, the air is ejected at a certain speed, which can blow off the dust and small particles attached to the surface of the profiled steel sheet, thereby improving the cleanliness of the profiled steel sheet surface and making the clamping block pair firmly clamp the profiled steel sheet.

[0018] 2. The profiled steel sheet stud welding device for waterproof roofing construction in this metallurgical plant has another part of the air inside the cavity one enters the ventilation channel through the slide groove and enters the interior of the clamping block two under the compression of the subsequent air. Because the clamping block two has an exhaust hole with a diameter smaller than the width of the clamping block two on one side, the air will be sprayed out quickly from the exhaust hole, blowing off the dust and small particles attached to the surface of the profiled steel sheet, further improving the cleanliness of the surface of the profiled steel sheet, and making the clamping block one clamp the profiled steel sheet more firmly.

[0019] 3. The roofing profiled steel sheet stud welding device used in the waterproofing construction of the metallurgical plant's profiled roof has another part of the air inside the cavity one entering the ventilation channel through the slide groove and then entering the cavity two under the compression of the subsequent air. Driven by the air, the clamping block two slides inside the cavity two. After the clamping block two slides out of the cavity two, it will contact the surface of the profiled steel sheet, thereby increasing the contact area and making the clamping of the profiled steel sheet more secure, further improving the clamping effect.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides a technical solution: such as Figures 1-9 As shown in Embodiment 1: A welding device for profiled steel sheet roofing of a metallurgical plant includes a column 1 and a base 2 fixedly installed at the bottom of the column 1. A bracket 4 is fixedly connected to the front of the column 1, and a welding device is provided on the side of the column 1.

[0033] An auxiliary positioning mechanism is provided on the top of the bracket 4; the auxiliary positioning mechanism includes a feeding unit and a clamping unit;

[0034] The clamping unit includes an installation platform 5, a hydraulic cylinder 501, a first clamping plate 502, a second clamping plate 503, and a first clamping block 504. The installation platform 5 is fixedly installed on the side of the column 1. The hydraulic cylinder 501 is installed on the top of the installation platform 5. The first clamping plate 502 is connected to the output end of the hydraulic cylinder 501. The second clamping plate 503 is fixedly connected to one side of the first clamping plate 502. The first clamping block 504 is disposed inside the second clamping plate 503.

[0035] The interior of clamping plate 2 503 is provided with cavity 1 5031 and cavity 2 5051 in sequence. Clamping block 1 504 is slidably connected to the interior of cavity 1 5031. Clamping block 2 505 is slidably connected to the interior of cavity 2 5051. The interior of clamping block 2 505 is hollow. One side of clamping block 2 505 is provided with an exhaust hole with a diameter smaller than the width of clamping block 2 505.

[0036] A groove 5034 is provided on one side of the inner wall of cavity 5031. A slider 5032 is slidably connected inside the groove 5034. A telescopic spring 5033 is fixedly connected to one side of clamping block 504. When clamping, clamping block 504 slides inside cavity 5031, which pushes slider 5032 to slide inside groove 5034. The telescopic spring 5033 is compressed to its maximum compression by clamping block 504. After welding is completed, hydraulic cylinder 501 is released, and under the action of the self-restoring force of telescopic spring 5033, clamping block 504 is pushed to reset and slide, allowing outside air to enter cavity 5031.

[0037] The clamping block 504 has a connecting pipe 5042 inside. A suction cup 5041 is fixedly connected to one side of the clamping block 504. A small gap is opened in the center of the suction cup 5041. The interior of the cavity 5051 is connected to the outside through the connecting pipe 5042 and the gap in the center of the suction cup 5041. The clamping plate 503 has a ventilation channel 5035 inside. The cavity 5031 and the cavity 5051 are connected through the ventilation channel 5035, and the ventilation channel 5035 is connected to the interior of the clamping block 505. After the air is ejected through the gap in the center of the suction cup 5041, the space inside the cavity 5031 is completely compressed. At this time, the suction cup 5041 will firmly adhere to the surface of the profiled steel plate due to the negative pressure, thereby improving the clamping effect of the clamping block 504 on the profiled steel plate.

[0038] The feeding unit includes a support base 401, a slide rail 402, a sliding block 403, a load-bearing plate 404, a telescopic hose 405, a strong magnetic block 406, and a magnetic plate 407. The support base 401 is fixedly connected to both sides of the bracket 4. The slide rail 402 is fixedly connected to the top of the support base 401. The sliding block 403 is slidably connected to the upper surface of the slide rail 402. The load-bearing plate 404 is fixedly connected to the side of the sliding block 403. The telescopic hose 405 is fixedly connected to the back of the load-bearing plate 404. The strong magnetic block 406 is fixedly connected to the end of the telescopic hose 405 away from the load-bearing plate 404. The magnetic plate 407 is fixedly connected to the top of the bracket 4. The strong magnetic block 406 and the magnetic plate 407 attract each other on their closest sides. When the strong magnetic block 406 and the magnetic plate 407 are attracted, they will pull the telescopic hose 405 to extend. The slide rail 402 is provided with two symmetrical rows. Both sides of the load-bearing plate 404 are slidably connected to the sliding block 403.

[0039] The welding device includes a connecting plate 3, a first cylinder 301, a lifting platform 302, a second cylinder 303, a connecting arm 304, and a welding head 305. The connecting plate 3 is fixedly connected to the side of the column 1. The first cylinder 301 is fixedly installed on the top of the connecting plate 3. The lifting platform 302 is connected to the output end of the first cylinder 301. The second cylinder 303 is fixedly installed on the top of the lifting platform 302. The connecting arm 304 is connected to the output end of the second cylinder 303. The welding head 305 is installed on the end of the connecting arm 304 away from the second cylinder 303. This welding device is existing technology, and its principle will not be described in detail here.

[0040] Example 2: The interior of clamping block 505 is a solid structure, and no vent is opened on one side. A fixed magnetic block 5053 is fixedly installed inside clamping plate 503. A sliding magnetic block 5052 is fixedly connected to one side of the interior of clamping block 505. The fixed magnetic block 5053 and the sliding magnetic block 5052 attract each other on the side closest to each other. Another part of the air inside cavity 5031 will enter the ventilation channel 5035 from the slide groove 5034 and enter the interior of cavity 5051 under the compression of the subsequent air. Because there is a certain distance between the fixed magnetic block 5053 and the sliding magnetic block 5052, the attraction between them is weakened. Therefore, under the push of the air, clamping block 505 slides inside cavity 5051. After clamping block 505 slides out of the interior of cavity 5051, it will contact the surface of the profiled steel plate, thereby increasing the contact area and making the clamping of the profiled steel plate more secure, further improving the clamping effect.

[0041] When welding the profiled steel sheet to the steel beam, the profiled steel sheet is first placed on top of the load-bearing plate 404. Then, the load-bearing plate 404 is pushed to drive the two sliding blocks 403 to slide on the upper surface of the slide rail 402, pushing the profiled steel sheet to the position to be welded. At this time, the strong magnetic block 406 and the magnetic plate 407 attract each other on the side that is close to each other. The magnetic plate 407 will attract the strong magnetic block 406 to move towards the magnetic plate 407 and be attracted together, thereby fixing the load-bearing plate 404 and the sliding block 403.

[0042] Then, the hydraulic cylinder 501 is activated, causing clamping plates 502 and 503 to move closer to one side of the hydraulic cylinder 501. Before clamping plate 503 contacts the side of the profiled steel sheet, clamping block 504 will first contact the profiled steel sheet. The profiled steel sheet squeezes clamping block 504 to slide inside cavity 5031. Some of the air inside cavity 5031 will enter the inside of connecting pipe 5042. The air is ejected from the inside of connecting pipe 5042 through the gap in the center of suction cup 5041. Because the diameter of the gap in the center of suction cup 5041 is much smaller than the diameter of connecting pipe 5042, the air will have a certain speed when it is ejected. This can blow off the dust and small particles attached to the surface of the profiled steel sheet covered by suction cup 5041, thereby improving the cleanliness of the profiled steel sheet surface and making clamping block 504 firmly clamp the profiled steel sheet.

[0043] Another portion of the air inside cavity 5031 enters the ventilation channel 5035 through the slide 5034 and enters the interior of clamping block 505 under the compression of subsequent air. Because clamping block 505 has an exhaust hole with a diameter smaller than the width of clamping block 505 on one side, air will be quickly ejected from the exhaust hole, blowing off the dust and small particles attached to the surface of the profiled steel sheet, further improving the cleanliness of the profiled steel sheet surface, making clamping block 504 clamp the profiled steel sheet more firmly. After clamping the profiled steel sheet, the welding stud is placed in the position to be welded. By starting cylinder 301 and cylinder 303, the position of connecting arm 304 and welding head 305 is changed, so that welding head 305 contacts the profiled steel sheet and welding stud for welding.
