Description

Technical Field

[0001] The invention relates to the technical field of steel structure butt welding, and more specifically to a steel structure butt welding adjustment device and method. Background Art

[0002] As a high-strength, corrosion-resistant and easy-to-process metal material, steel pipes are used in construction, machinery manufacturing and industry, energy industry, transportation, and furniture and decoration.

[0003] Chinese patent application number CN202310703922.8 discloses a pipeline welding machine, comprising: a base, on which two support frames on the top are respectively fitted with corresponding rotating rings, a limit ring is fixedly installed on the ring surface of the rotating ring, the two are coaxially arranged, and the limit ring is embedded in the side wall of the support frame of the base to form a rotation limit structure, and the two rotating rings are coaxially arranged; it also includes: a clamping plate, which has three clamping plates distributed at equal angles around the axis of the rotating ring, the clamping plate and the tube body are located on the inner side of the rotating ring, and the tube body and the rotating ring are coaxially arranged, and the three clamping plates are tightly fitted on the outer wall of the tube body to form a fixed clamping structure, and the output end of the first electric cylinder is fixedly and vertically installed at the center of one side of the clamping plate away from the tube body.

[0004] In the above technical scheme, pipes of different diameters can be quickly fixed, and the device is provided with an automatic grinding structure for the pipe welding part, which does not require manual grinding by workers, thereby improving work efficiency. However, the three clamping plates are tightly fitted on the outer wall of the pipe body to form a fixed clamping structure. Since the clamping plates are rectangular plates, the fixation of the two steel pipes by the rectangular plates is not stable. In addition, the three retractors cannot be guaranteed to be extended without error, resulting in positional displacement of the two steel pipes. The two steel pipes are not aligned, resulting in the two steel pipes after welding not being on the same central axis, affecting the welding quality of the pipeline by the welding equipment. Moreover, in the process of welding the steel pipe by most welding equipment, the steel pipe is aligned and clamped and fixed, and the welding device welds along the weld surface of the steel pipe. The above scheme adopts a welding device for fixing, and the steel pipe is rotated for welding. Since the temperature at the welding place is high, a local molten pool will be generated. The centrifugal force generated by the rotation of the steel pipe may affect the metal flow in the welding molten pool, thereby affecting the welding quality of the steel pipe by the welding device.

During the process of clamping and fixing the two steel pipes, the clamps move synchronously to clamp and fix the steel pipes at the center line position of the first insert pipe and the second insert pipe.

[0016] By adopting the above technical scheme, during the process of inserting the steel pipe into the first insert pipe and the second insert pipe and fixing it, the end surface of the steel pipe will squeeze the rotating guard plate, and the rotating guard plate rotates and contacts the surface of the steel pipe under the action of the spring shaft, and the position where the rotating guard plate contacts the surface of the steel pipe is located on both sides of the welding position of the two steel pipes. As the two steel pipes are clamped, the steel pipe moves toward the center line position of the first insert pipe and the second insert pipe. At this time, the steel pipe squeezes the rotating guard plate and moves the lifting rod upward to squeeze the second spring. At this time, the rotating guard plate fits the surface of the steel pipe under the action of the second spring, and the welding head rotates with the rotating frame, the lifting rod also moves with the rotating frame, and the rotating guard plate rotates with the welding head to prevent welding slag generated during the welding of the welding head from splashing onto the surface of the steel pipe, thereby ensuring the cleanliness of the surface of the steel pipe, and reducing the later grinding of the steel pipe surface, thereby ensuring the neat appearance of the steel pipe.

[0019] A steel structure butt welding adjustment method, the steps are as follows: S1: First, two steel pipes to be welded are inserted from one end of the first insert pipe and the second insert pipe respectively. When the parts to be welded of the two steel pipes are located below the welding head, the two steel pipes are stopped from being inserted into the first insert pipe and the second insert pipe. At this time, the second motor rotates in the opposite direction to rotate the shaft, so that the two missing gears rotate and the two rotating teeth rotate inside the ring frame. The two rotating teeth rotate at the same time to rotate the multiple slope blocks to squeeze the guide rods. In the process, the first spring is stretched. At this time, the multiple guide rods move synchronously to move the clamping plate to lift the steel pipes. As the rotating teeth continue to rotate at the same time, the clamping plate clamps and fixes the steel pipes at the center line position of the first insert pipe and the second insert pipe, ensuring that the two bare pipes are aligned before welding; S2: The welding head extends to a distance adapted to the position of the steel pipe to be welded, the first motor rotates to drive the gear wheel to rotate, the gear wheel rotates to drive the gear ring to rotate in the ring groove, the gear ring rotates to drive the rotating frame to rotate, so that the welding head rotates with the rotating frame, and the welding head works during the rotation, and the welding head performs one-time welding around the position of the steel pipe to be welded; S3: After welding is completed, the welding head stops working and moves to reset. At this time, the second motor rotates forward and drives the rotating shaft to rotate, so that the two missing gears rotate and drive the two rotating teeth to rotate inside the ring frame. At this time, the slope block is reset under the action of the rotation of the rotating teeth. At this time, the guide rod is reset under the action of the first spring and drives the clamping plate to reset, thereby releasing the clamping of the welded steel pipe, and then the welded steel pipe is pulled out from one end of the first insertion tube.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 1) When the steel structure butt welding adjustment device is in use, the two missing gears rotate and drive the two rotating teeth to rotate inside the ring frame. The two rotating teeth rotate at the same time and drive multiple slope blocks to rotate and squeeze the guide rod. At this time, multiple guide rods move synchronously and drive the clamping plate to lift the steel pipe. As the rotating teeth continue to rotate simultaneously, the clamping plate clamps and fixes the steel pipe at the center line position of the first plug and the second plug, ensuring the alignment of the two bare pipes before welding. The geared wheel rotates and drives the gear ring to rotate in the ring groove. The gear ring rotates and drives the rotating frame to rotate, so that the welding head rotates with the rotating frame. The welding head works during the rotation process, and the welding head performs one-time welding around the steel pipe to be welded position. Compared with the traditional welding device, during the process of the two steel pipes being clamped and fixed, the clamping plate moves synchronously to clamp and fix the steel pipe at the center line position of the first plug and the second plug, ensuring the alignment before welding of the steel pipes, and the welding head rotates around the steel pipe to be welded position for one-time welding, which prevents the centrifugal force generated by the rotation of the steel pipe from affecting the metal flow of the welding molten pool, which not only improves the welding speed of the welding device for the steel pipe, but also improves the welding quality of the welding device for the steel pipe.

[0021] 2) When the steel structure butt welding adjustment device is in use, during the process of the steel pipe being inserted into the first insert tube and the second insert tube and being fixed, the end surface of the steel pipe will squeeze the rotating guard plate, and the rotating guard plate rotates and contacts the surface of the steel pipe under the action of the spring shaft, and the position where the rotating guard plate contacts the surface of the steel pipe is located on both sides of the welding position of the two steel pipes. As the two steel pipes are clamped, the steel pipe moves toward the center line position of the first insert tube and the second insert tube. At this time, the steel pipe squeezes the rotating guard plate to move upward with the lifting rod to squeeze the second spring. At this time, the rotating guard plate fits the surface of the steel pipe under the action of the second spring, and during the process of the welding head following the rotation of the rotating frame, the lifting rod also follows the movement of the rotating frame, and the rotating guard plate rotates with the welding head to prevent welding slag generated during the welding of the welding head from splashing onto the surface of the steel pipe, thereby ensuring the cleanliness of the surface of the steel pipe, and reducing the later grinding of the steel pipe surface, thereby ensuring the neat appearance of the steel pipe.

[0022] 3) When the steel structure butt welding adjustment device is in use, the two rotating teeth rotate simultaneously and drive the multiple slope blocks to rotate to squeeze the guide rod. At this time, the multiple guide rods move synchronously and drive the clamping plate to lift the steel pipe. As the rotating teeth continue to rotate simultaneously, the clamping plate clamps the steel pipe and fixes it at the center line position of the first plug pipe and the second plug pipe, so as to achieve butt welding of steel pipes of different diameters and increase the practicality of the welding device.

[0032] The use steps of the present invention are as follows: when the steel structure butt welding adjustment device is used, firstly, two steel pipes to be welded are respectively inserted from one end of the first insert pipe 1 and the second insert pipe 2. When the parts to be welded of the two steel pipes are located below the welding head 7, the two steel pipes are stopped from continuing to be inserted into the first insert pipe 1 and the second insert pipe 2. At this time, the second motor 25 rotates in the opposite direction to rotate the rotating shaft 23, so that the two missing gears 24 rotate to rotate with the two rotating teeth 16 inside the ring frame 15. The two rotating teeth 16 rotate at the same time to rotate with the multiple slope blocks 17 to squeeze the guide rod 10. In the process, the first spring 12 is stretched.

In the process of the steel pipe being inserted into the first insert tube 1 and the second insert tube 2 and fixed, the end surface of the steel pipe will squeeze the rotation guard plates 30, and the rotation guard plates 30 rotate under the action of the spring shaft 29. The rotating guard plate 30 contacts the surface of the steel pipe, and the position where the rotating guard plate 30 contacts the surface of the steel pipe is located on both sides of the welding position of the two steel pipes. As the two steel pipes are clamped, the steel pipes move toward the center line position of the first insert pipe 1 and the second insert pipe 2. At this time, the steel pipe squeezes the rotating guard plate 30 to move with the lifting rod 26 to move upward to squeeze the second spring 28.

During the rotation of the welding head 7 following the rotating frame 6, the lifting rod 26 also moves with the rotating frame 6, and the rotating guard plate 30 rotates with the welding head 7 to prevent the welding slag generated during the welding process of the welding head 7 from splashing onto the surface of the steel pipe, thereby ensuring the cleanliness of the surface of the steel pipe, and reducing the later grinding of the steel pipe surface, thereby ensuring the neatness of the appearance of the steel pipe.

[0034] A square plate 27 is fixedly installed on the bottom surface of the two lifting rods 26, and a second spring 28 is sleeved on the surface of the two lifting rods 26. One end of the second spring 28 is fixedly connected to the bottom surface of the rotating frame 6, and the other end of the second spring 28 is fixedly connected to the surface of the square plate 27. Under the action of the second spring 28, the rotating guard plate 30 fits with the surface of the steel pipe.

[0035] The use steps of the present invention are as follows: when the steel structure butt welding adjustment device is in use, during the welding process of the welding head 7 to the steel pipe, in order to prevent the welding splashes from reaching the surface of the steel pipe, during the process of the steel pipe being inserted into the first insert pipe 1 and the second insert pipe 2 and fixed, the end surface of the steel pipe will squeeze the rotating guard plate 30, and the rotating guard plate 30 will rotate and contact the surface of the steel pipe under the action of the spring shaft 29, and the position where the rotating guard plate 30 contacts the surface of the steel pipe is located on both sides of the welding position of the two steel pipes. As the two steel pipes are clamped, the steel pipe is moved toward the center of the first insert pipe 1 and the second insert pipe 2. The lifting rod 26 moves along the rotating frame 6, and the rotating guard plate 30 rotates along the welding head 7 to prevent the welding slag generated during the welding of the welding head 7 from splashing onto the surface of the steel pipe, thereby ensuring the cleanliness of the surface of the steel pipe and reducing the need for grinding the surface of the steel pipe in the later stage, thereby ensuring the neatness of the appearance of the steel pipe.

[0036] A steel structure butt welding adjustment method, the steps are as follows: S1: First, two steel pipes to be welded are inserted from one end of the first insert pipe 1 and the second insert pipe 2 respectively. When the parts to be welded of the two steel pipes are located below the welding head 7, the two steel pipes are stopped from being inserted into the first insert pipe 1 and the second insert pipe 2. At this time, the second motor 25 rotates in the opposite direction to drive the rotating shaft 23 to rotate, so that the two missing gears 24 rotate and drive the two rotating teeth 16 to rotate inside the ring frame 15.
