[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] Embodiment 1:

[0029] Please refer to the attached Figure 1 - attached Figure 8 , the embodiment of the present invention provides a welding device for steel pipe materials in construction engineering, including a mobile chassis 1. A mounting frame 2 is fixedly connected to the top of the mobile chassis 1. The mounting frame 2 is used to provide a mounting position. A mounting frame 3 is fixedly connected to the top of the mounting frame 2. A rotating mechanism 4 is arranged on the top of the mounting frame 3. The mounting frame 3 is used to fix the rotating mechanism 4. A positioning mechanism 5 is arranged inside the rotating mechanism 4. A welding and grinding mechanism 6 is arranged outside the positioning mechanism 5. The positioning mechanism 5 can fix the device on the steel pipe, and the rotating mechanism 4 can drive the positioning mechanism 5 to rotate, so that the welding and grinding mechanism 6 can be used to weld the steel pipe and grind the weld flat at the same time.

[0030] The rotating mechanism 4 includes a liquid storage tank 401 which can provide a water storage space. The bottom of the liquid storage tank 401 is fixedly connected to the top of the mobile chassis 1. The top of the liquid storage tank 401 is fixedly connected with a water pump 402 which can provide power for the flow of the liquid. The input end of the water pump 402 is fixedly connected with a water suction pipe 403 which plays a connecting role. The output end of the water pump 402 is fixedly connected with a water outlet hose 404 which can also play a connecting role. The top of the installation frame 3 is fixedly connected with a fixing ring 405 which provides an installation space and can also provide a temporary water storage space after water flows into the fixing ring 405. The inside of the fixing ring 405 is rotatably connected with an impeller ring 406 which can rotate under the action of water flow. The inner side of the impeller ring 406 is fixedly connected with a rotating installation ring 407 which can provide an installation position and can be driven to rotate by the impeller ring 406. The outside of the rotating installation ring 407 is rotatably connected to the inside of the fixing ring 405. The outside of the liquid storage tank 401 is fixedly connected with a water collecting tank 408 which can realize a water receiving space and the repeated utilization of water flow. A filter plate 409 is arranged between the water collecting tank 408 and the liquid storage tank 401. The bottom of the water suction pipe 403 is arranged inside the liquid storage tank 401. One end of the water outlet hose 404 far away from the water pump 402 is fixedly connected to the outside of the fixing ring 405. When welding and grinding are carried out, the water pump 402 is started. The water pump 402 sucks out the liquid in the liquid storage tank 401 through the water suction pipe 403 and allows the water flow to enter the inside of the fixing ring 405 through the water outlet hose 404. At this time, under the action of the high-pressure water flow, the impeller ring 406 can be driven to rotate. After the impeller ring 406 rotates, it drives the rotating installation ring 407 to rotate, and then can drive the positioning mechanism 5 to rotate. At the same time, the water flow generated during grinding will fall into the water collecting tank 408, and the water falling into the water collecting tank 408 is filtered by the filter plate 409, thus facilitating the repeated use of the liquid.

[0031] The positioning mechanism 5 includes a mounting ring 501. The mounting ring 501 can be installed inside the rotating mounting ring 407, and then can drive the mounting ring 501 to rotate when the rotating mounting ring 407 rotates. The outside of the mounting ring 501 is fixedly connected to the inside of the rotating mounting ring 407. A rotating frame 502 is rotatably connected to the outside of the mounting ring 501. A plurality of rotating sliding sleeves 503 are rotatably connected to the middle of the rotating frame 502. A clamping arm 504 is slidably connected to the inside of the rotating sliding sleeve 503. When the rotating frame 502 rotates, it can drive the rotating sliding sleeve 503 to rotate, so as to drive the clamping arm 504 to rotate. A clamping disc 505 is rotatably connected to the inside of the clamping arm 504. The clamping disc 505 can clamp the outer wall of the steel pipe. A hydraulic cylinder 506 is rotatably connected to the outside of the rotating mounting ring 407. The hydraulic cylinder 506 can provide power for the rotation of the rotating frame 502. The output end of the hydraulic cylinder 506 is rotatably connected to the inside of the rotating frame 502. An anti-slip sleeve is sleeved outside the clamping disc 505. One side of the clamping arm 504 away from the clamping disc 505 is rotatably connected to the outside of the rotating mounting ring 407. When welding the steel pipe material, first put the mounting ring 501 on the steel pipe, align the welding and grinding mechanism 6 with the welding position of the steel pipe, start the hydraulic cylinder 506, the output end of the hydraulic cylinder 506 extends, driving the rotating frame 502 to rotate. After the rotating frame 502 rotates, it drives the rotating sliding sleeve 503 to rotate, and then can force the clamping arm 504 to rotate while moving the clamping disc 505 towards the middle through rotation, so as to clamp the steel pipe. At this time, the stability of the welding device on the steel pipe is maintained.

[0032] The welding and grinding mechanism 6 includes two mounting plates 601 which can be mounted on the outer wall of the rotating frame 502. Both mounting plates 601 are fixedly connected to the outside of the rotating frame 502. A sliding groove 602 is formed inside the mounting plate 601. A sliding block 603 is slidably connected inside the sliding groove 602 and can slide inside the sliding groove 602. To maintain the stability of the sliding block 603 during sliding, on the side of the mounting plate 601 close to the fixed ring 405, a hydraulic rod 604 is fixedly connected. The output end of the hydraulic rod 604 is fixedly connected to a connecting bent rod 605. On the side of one sliding block 603 away from the mounting plate 601, a laser welding gun 606 is fixedly connected. The connecting bent rod 605 can play a connecting role between the hydraulic rod 604 and the laser welding gun 606. At the same time, the hydraulic rod 604 can drive the laser welding gun 606 to slide. On the side of the other sliding block 603 away from the mounting plate 601, a grinding machine 607 is fixedly connected. The grinding machine 607 can play a grinding role. On the side of the grinding machine 607 away from the mounting plate 601, a water spray gun 608 is fixedly connected. The water spray gun 608 can spray water. A water passing flexible hose 609 is fixedly connected to the outside of the water spray gun 608. The water passing flexible hose 609 can play a connecting role between the fixed ring 405 and the water spray gun 608. On the outside of the grinding machine 607, a mounting bent rod 610 is fixedly connected. The mounting bent rod 610 can provide a mounting space. A pressing spring 611 is fixedly connected inside the mounting bent rod 610. On the side of the pressing spring 611 away from the connecting bent rod 605, a limiting circular block 612 is fixedly connected. On the side of the limiting circular block 612 away from the pressing spring 611, a hexagonal prism 613 is fixedly connected. On the side of the hexagonal prism 613 away from the limiting circular block 612, a water shielding cover 614 is fixedly connected. The pressing spring 611 can use its own reaction force to give a thrust to the limiting circular block 612, and then it can be transmitted to the water shielding cover 614 through the hexagonal prism 613, so that the water shielding cover 614 closely adheres to the outer wall of the steel pipe. The limiting circular block 612 is slidably connected inside the mounting bent rod 610. The outside of the hexagonal prism 613 penetrates through the side of the mounting bent rod 610 away from the connecting bent rod 605. A rubber sleeve is sleeved on the outside of the water shielding cover 614. The side of the water passing flexible hose 609 away from the water spray gun 608 is fixedly connected to the inside of the rotating mounting ring 407. One end of the connecting bent rod 605 away from the mounting plate 601 is fixedly connected to the top of the laser welding gun 606. The other end of the connecting bent rod 605 away from the mounting plate 601 is fixedly connected to the top of the grinding machine 607. The end of the water passing flexible hose 609 away from the water spray gun 608 penetrates through the inside of the impeller ring 406. The bottom of the mounting frame 2 penetrates through the bottom of the water collecting tank 408. When fixing the device on the steel pipe, start the hydraulic rod 604. The output end of the hydraulic rod 604 retracts, so that the laser welding gun 606 and the grinding machine 607 can be driven by the connecting bent rod 605 to move towards the middle, and then the laser welding gun 606 and the grinding machine 607 can be aligned with the welding joint of the steel pipe.At this time, the laser welding torch 606 is started. At the same time, the rotating mechanism 4 is started. After the rotating mechanism 4 is started, it drives the positioning mechanism 5 to rotate, so as to drive the laser welding torch 606 to rotate, and then the laser welding torch 606 can weld the area to be welded of the steel pipe. At the same time, the grinding machine 607 is started. When the positioning mechanism 5 rotates, the grinding machine 607 also rotates, and then the weld of the steel pipe can be ground. When the grinding machine 607 moves towards the middle steel pipe, it drives the installation bent rod 610 to move towards the weld of the steel pipe. When the water shield 614 contacts the steel pipe, since the grinding machine 607 continues to move towards the steel pipe, the hexagonal prism 613 moves into the interior of the installation bent rod 610, and then can drive the limiting round block 612 to compress and press the spring 611. At this time, the water shield 614 closely adheres to the outer wall of the steel pipe. At the same time, after the rotating mechanism 4 is started, the interior of the rotating mechanism 4 is filled with liquid. At this time, the liquid inside the rotating mechanism 4 enters the interior of the water spray gun 608 through the water passing hose 609, so as to be able to spray water through the water spray gun 608 and aim at the grinding area of the grinding machine 607. Therefore, dust reduction and temperature reduction can be achieved during grinding. At the same time, when the laser welding torch 606 rotates to the lower part of the steel pipe, the water flow can be guided out of the welding area through the water shield 614, so as to avoid the influence of the water flow on the welding of the laser welding torch 606.,

[0033] Embodiment Two:

[0034] Different from Embodiment One, the present invention can independently drive the laser welding torch 606 to grind the welded area of the steel pipe after welding by separately arranging the hydraulic rods 604 and connecting bent rods 605 on the laser welding torch 606 and the grinding machine 607. At the same time, the outer surface of the steel pipe can also be ground and polished;

[0035] Embodiment Three:

[0036] Different from Embodiment One and Embodiment Two, after welding the steel pipe with the laser welding torch 606, the present invention can weld the imperfect parts again, and grind them again with the grinding machine 607. At the same time, the cracks of the steel pipe can also be welded and ground.

[0037] Working principle: When welding the steel pipe material, first put the installation ring 501 on the steel pipe, align the welding and grinding mechanism 6 with the area to be welded of the steel pipe, start the hydraulic cylinder 506, the output end of the hydraulic cylinder 506 extends, driving the rotating frame 502 to rotate. After the rotating frame 502 rotates, it drives the rotating sliding sleeve 503 to rotate, and then can force the clamping arm 504 to rotate while moving the clamping disc 505 towards the middle through rotation, and then the steel pipe can be clamped. At this time, the stability of the welding device on the steel pipe is maintained;

[0038] When fixing the device on the steel pipe, start the hydraulic rod 604. The output end of the hydraulic rod 604 retracts, so that the laser welding gun 606 and the grinding machine 607 can be driven by the connecting bent rod 605 to move towards the middle, and then the laser welding gun 606 and the grinding machine 607 can be aligned with the welding position of the steel pipe. At this time, start the laser welding gun 606. At the same time, start the rotating mechanism 4. After the rotating mechanism 4 starts, it drives the positioning mechanism 5 to rotate, so that the laser welding gun 606 can be driven to rotate, and then the laser welding gun 606 can weld the area to be welded on the steel pipe. At the same time, start the grinding machine 607. When the positioning mechanism 5 rotates, the grinding machine 607 also rotates, and then the weld of the steel pipe can be ground. When the grinding machine 607 moves towards the middle steel pipe, it drives the installation bent rod 610 to move towards the weld of the steel pipe. When the water shield 614 touches the steel pipe, since the grinding machine 607 continues to move towards the steel pipe, the hexagonal prism 613 moves into the interior of the installation bent rod 610, and then the limiting round block 612 can be driven to compress the abutting spring 611. At this time, the water shield 614 closely adheres to the outer wall of the steel pipe. At the same time, after the rotating mechanism 4 starts, the interior of the rotating mechanism 4 is filled with liquid. At this time, the liquid inside the rotating mechanism 4 enters the interior of the water spray gun 608 through the water passing hose 609, so that the water spray gun 608 can spray water flow and aim at the grinding area of the grinding machine 607. Therefore, dust reduction and temperature reduction can be achieved during grinding. At the same time, when the laser welding gun 606 rotates to the lower part of the steel pipe, the water flow can be guided out of the welding area through the water shield 614, so as to avoid the influence of the water flow on the welding of the laser welding gun 606;

[0039] When performing welding and grinding, start the water pump 402. The input end of the water pump 402 pumps the liquid in the liquid storage tank 401 through the water suction pipe 403, and the water flow is introduced into the interior of the fixed ring 405 through the water outlet hose 404. At this time, under the action of the high-pressure water flow, the impeller ring 406 can be driven to rotate. After the impeller ring 406 rotates, it drives the rotating installation ring 407 to rotate, and then the positioning mechanism 5 can be driven to rotate. At the same time, the water flow generated during grinding will fall into the water collecting tank 408, and the water falling into the water collecting tank 408 is filtered through the filter plate 409, and then the liquid can be conveniently reused.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
