[0002] In the process of building a steel pipe tower, it is necessary to weld short sections of steel pipes and assemble them through flanges, bolts and other fixing structures and components.

[0003] For example, a welding device for splicing seams of a steel pipe tower with announcement number CN219152023U can drive the welded steel pipe to rotate through the clamping rotating parts on both sides, and the limiting structure and anti-drop ring can keep the steel pipe in a stable stress state to avoid weld breakage during rotation. At the same time, the limiting structure can cope with different steel pipe diameters, and its contact area is small, the friction resistance is small, and it is easy to adjust, so that it has a wider applicable diameter range, which is convenient for cooperating with the welding machine to complete 360-degree welding operations. However, in actual use, the steel pipe is positioned by the limiting top plate and the limiting side plate. Although the steel pipe can be positioned and clamped, when the steel pipe is rotated to adjust the welding position, the limiting top plate and the limiting side plate will generate friction with the steel pipe, affecting the rotation of the steel pipe, and due to the existence of the limiting top plate and the limiting side plate, it is not convenient to place and remove the steel pipe, and it is not convenient to use, and there are certain defects in use.

[0028] By adopting the above technical solution, it is convenient to adjust the positions of the two steel pipes and to butt the steel pipes.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: the steel pipe jointing device provided with the alignment adjustment mechanism is provided with a positioning assembly above the base, which is convenient for users to adjust the positions of the two steel pipes, facilitate the alignment adjustment of the steel pipes, and facilitate the placement and removal of the steel pipes, and can stably position the steel pipes to avoid displacement caused by the rotation of the steel pipes, thereby improving the quality of steel pipe welding;

[0030] 1. A positioning assembly is provided above the base. When welding the two steel pipes, the two steel pipes are placed in two sets of positioning seats respectively, so that the steel pipes are in contact with the rotating wheel. The gravity of the steel pipes can drive the supporting wheel to descend, so that the movable rod moves up and down on the fixed frame and stretches the telescopic spring, so that the fixed block can be driven to move. After the fixed block moves, the first mounting rod can be pulled to rotate by the connecting rope. After the first mounting rod rotates, the connecting rod can be driven to rotate between the supporting frames. After the connecting rod rotates, the second mounting rod is driven to rotate. The length of the second mounting rod is much larger than the first mounting rod. When the first mounting rod and the second mounting rod rotate at the same angle, the swing amplitude of the second mounting rod is much larger than the first mounting rod. The rotation of the second mounting rod can pull the pull rope to move. If the steel pipe is lighter, although the movable rod moves a small displacement, the swing amplitude of the second mounting rod can be guaranteed, and then the movable block is driven to move by the pull rope. After the movable block moves, the compression spring can be compressed, and the sliding rod can be pushed to move, so that the stabilizing wheel can be pushed to move, so that the stabilizing wheel contacts the upper side of the steel pipe, and downward pressure can be provided to the steel pipe to avoid the occurrence of channeling during the rotation of the steel pipe. The movable block can be moved to avoid affecting the welding quality of the steel pipe. If the fixed block moves down and continues to pull the first mounting rod to rotate after the stabilizing wheel contacts the steel pipe, the movable block can be continued to be pulled to move, so that the movable block slides on the sliding rod to stretch the adaptive spring, which is suitable for fixing steel pipes of different sizes, and thus the steel pipe can be reliably positioned, and the stability of the steel pipe can be guaranteed during the rotation process. The bidirectional screw rod can be driven to rotate by starting the rotating motor, and after the bidirectional screw rod rotates, the two sets of positioning seats can be driven to approach each other, and the spacing between the two steel pipes can be adjusted, which is convenient for aligning the steel pipes. When adjusting the welding position of the steel pipe joint, the driving motor is started to drive the rotating shaft on one side to rotate, and after the rotating shaft on one side rotates, the rotating rod can be driven to rotate through the cooperation of the connecting groove and the connecting shaft, and after the rotating rod rotates, the rotating shaft on the other side can be driven to rotate, so that the two sets of rotating wheels can be rotated, and then the steel pipe can be driven to rotate, and the welding position of the steel pipe can be adjusted. The positioning assembly is convenient for users to adjust the position of the two steel pipes, which is convenient for adjusting the alignment of the steel pipe, and is convenient for placing and removing the steel pipe, and the steel pipe can be stably positioned to avoid displacement during the rotation of the steel pipe, thereby improving the quality of steel pipe welding.

[0031] 2. When adjusting the welding position after aligning the steel pipes, the two steel pipes can be rotated half a circle before welding through the welding gun. During the rotation of the steel pipe, the rotating rod rotates, and the rotating rod drives the fixed ring to rotate. After the fixed ring rotates, it drives the fixed seat to rotate in a circle. The ball on the fixed seat can push the push rod to move. After the push rod moves, it can drive the movable plate to move, so that the grinding block moves. After the movable plate moves, it drives the limit rod to slide on the limit frame, so that the reset spring can be compressed or stretched. After the ball rotates away from the push rod, the movable plate is reset under the action of the reset spring, and then the movable plate can be moved back and forth by continuously rotating the rotating rod, so that the joint welding of the two steel pipes can be polished, and the rust or oil stains on the welding can be removed to avoid affecting the welding quality of the steel pipe;

[0032] 3. The movable plate can drive the moving rod to move back and forth during the reciprocating movement, so that the piston moves back and forth inside the cylinder. When the piston moves to the right, the one-way valve inside the air inlet is closed, and the one-way valve inside the air outlet pipe is opened, so that the internal air of the cylinder can be ejected through the air outlet pipe. When the piston moves to the left, the one-way valve inside the air inlet is opened, and the one-way valve inside the air outlet pipe is closed, so that the outside air is drawn into the cylinder through the air inlet. As the rotating rod rotates, the air outlet pipe can continuously eject air, so that the air inside the cylinder can be ejected. Air is blown at the grinding part of the steel pipe to increase the air flow rate, which can prevent the dust generated by grinding from adhering to the steel pipe and affecting the subsequent welding quality. The movable plate can drive the connecting frame to move back and forth during the reciprocating movement. After the connecting frame moves back and forth, the meshing of the rack and the rotating gear can drive the air outlet pipe to rotate back and forth on the cylinder body, thereby expanding the blowing range of the air outlet pipe, expanding the cleaning range of the steel pipe, improving the cleaning quality, avoiding the smaller blowing range due to reducing the outlet diameter to ensure the flow rate, and improving practicality.

[0055] Embodiment 1: Figure 1-Figure 4 and Fig. 9As shown, a positioning assembly 2 is provided above the base 1. When welding two steel pipes, the two steel pipes are placed in two sets of positioning seats 201 respectively, so that the steel pipes are in contact with the rotating wheel 205. The gravity of the steel pipes can drive the supporting wheel 210 to descend, so that the movable rod 208 moves up and down on the fixing frame 207 and stretches the telescopic spring 211, so that the fixing block 212 can be driven to move.

[0060] A connecting frame 245 is symmetrically installed on the top of the two fixing rods 234, and a rotating gear 247 is fixedly installed on the outer side of the air outlet pipe 243, and a rack 246 is fixedly installed on the side of the connecting frame 245 close to the rotating gear 247, and the rack 246 is meshed and connected with the rotating gear 247.

[0061] Embodiment 3: Figure 6-Figure 7 As shown, the movable plate 230 can drive the movable rod 242 to move back and forth during the reciprocating movement, so that the piston 241 moves back and forth inside the cylinder 239. When the piston 241 moves to the right, the one-way valve inside the air inlet 244 is closed, and the one-way valve inside the air outlet pipe 243 is opened, so that the internal air of the cylinder 239 can be ejected through the air outlet pipe 243. When the piston 241 moves to the left, the one-way valve inside the air inlet 244 is opened, and the one-way valve inside the air outlet pipe 243 is closed, so that the outside air is sucked into the cylinder 239 through the air inlet 244. As the rotating rod 227 rotates, the air outlet pipe 243 can be continuously opened. The jet is jetted, so that the polished part of the steel pipe can be blown, and the air flow rate can be increased, which can prevent the dust generated by the grinding from adhering to the steel pipe and affecting the subsequent welding quality. The movable plate 230 can drive the connecting frame 245 to move back and forth during the reciprocating movement. After the connecting frame 245 moves back and forth, the meshing of the rack 246 and the rotating gear 247 can drive the air outlet pipe 243 to rotate back and forth on the cylinder 239, thereby expanding the blowing range of the air outlet pipe 243, expanding the cleaning range of the steel pipe, improving the cleaning quality, and avoiding the smaller blowing range due to reducing the outlet diameter to ensure the flow rate, thereby improving practicality.

[0062] Working principle: When using the steel pipe jointing device with a positioning adjustment mechanism, first, according to Figure 1-Figure 9As shown, when welding two steel pipes, the two steel pipes are placed in two sets of positioning seats 201 respectively, so that the steel pipes are in contact with the rotating wheel 205, and the gravity of the steel pipes can drive the supporting wheel 210 to descend, so that the movable rod 208 moves up and down on the fixing frame 207 and stretches the telescopic spring 211, so that the fixing block 212 can be driven to move, and after the fixing block 212 moves, the first installation rod 216 can be pulled to rotate through the connecting rope 213, and after the first installation rod 216 rotates, it can drive the connecting rod 215 to rotate between the supporting frames 214, and after the connecting rod 215 rotates, it drives the second installation rod 217 to rotate, and the length of the second installation rod 217 is much greater than that of the first installation rod 216. When the first mounting rod 216 and the second mounting rod 217 rotate at the same angle, the swing amplitude of the second mounting rod 217 is much greater than that of the first mounting rod 216. The rotation of the second mounting rod 217 can pull the pull rope 223 to move. If the steel pipe is light, although the movable rod 208 moves at a small displacement, the swing amplitude of the second mounting rod 217 can be guaranteed, and then the movable block 2202 can be driven to move through the pull rope 223. After the movable block 2202 moves, the compression spring 2201 can be compressed, and the sliding rod 220 can be pushed to move, so that the stabilizing wheel 222 can be pushed to move, so that the stabilizing wheel 222 contacts the upper side of the steel pipe, which can provide downward pressure on the steel pipe. To avoid the steel pipe from moving during rotation and affecting the welding quality of the steel pipe, if the fixed block 212 moves down and continues to pull the first mounting rod 216 to rotate after the stabilizing wheel 222 contacts the steel pipe, the movable block 2202 can continue to move, so that the movable block 2202 slides on the sliding rod 220 to stretch the adaptive spring 224, which is suitable for fixing steel pipes of different sizes, and thus the steel pipe can be reliably positioned, and the stability of the steel pipe can be guaranteed during the rotation process. By starting the rotating motor 302, the bidirectional screw rod 303 can be driven to rotate. After the bidirectional screw rod 303 rotates, the two sets of positioning seats 201 can be driven to approach each other, so that the distance between the two steel pipes can be adjusted, which is convenient for aligning the steel pipes. The pipes are aligned, and when adjusting the welding position of the steel pipe joint, the driving motor 206 is started to drive the rotating shaft 204 on one side to rotate. After the rotating shaft 204 on one side rotates, the connecting groove 229 and the connecting shaft 228 can drive the rotating rod 227 to rotate. After the rotating rod 227 rotates, the rotating shaft 204 on the other side can be driven to rotate, so that the two sets of rotating wheels 205 rotate, and then the steel pipe can be driven to rotate, and the welding position of the steel pipe can be adjusted. The positioning assembly 2 is convenient for users to adjust the positions of the two steel pipes, and it is convenient to adjust the position of the steel pipe, and it is convenient to place and remove the steel pipe. The steel pipe can be stably positioned to avoid displacement of the steel pipe during rotation, thereby improving the quality of steel pipe welding;

[0063] When adjusting the welding position after aligning the steel pipes, the two steel pipes can be rotated half a circle before welding by the welding gun. During the rotation of the steel pipes, the rotating rod 227 rotates, and the rotating rod 227 drives the fixing ring 236 to rotate. After the fixing ring 236 rotates, it drives the fixing seat 237 to rotate in a circle. The ball 238 on the fixing seat 237 can push the push rod 235 to move. After the push rod 235 moves, it can drive the movable plate 230 to move, so that the grinding block 231 moves. After the movable plate 230 moves, it drives the limit rod 233 to slide on the limit frame 232, so that The return spring 2331 can be compressed or stretched. After the ball 238 rotates away from the push rod 235, the movable plate 230 is reset under the action of the return spring 2331. Then, the movable plate 230 can be moved back and forth by continuously rotating the rotating rod 227, so that the joint welding part of the two steel pipes can be polished, and the rust or oil stain on the welding part can be removed to avoid affecting the welding quality of the steel pipe. During the reciprocating movement, the movable plate 230 can drive the moving rod 242 to move back and forth, so that the piston 241 can be moved in the cylinder 239. When the piston 241 moves back and forth inside, when the piston 241 moves to the right, the one-way valve inside the air inlet 244 is closed, and the one-way valve inside the air outlet pipe 243 is opened, so that the internal air of the cylinder 239 can be ejected through the air outlet pipe 243. When the piston 241 moves to the left, the one-way valve inside the air inlet 244 is opened, and the one-way valve inside the air outlet pipe 243 is closed, so that the outside air is sucked into the cylinder 239 through the air inlet 244. With the rotation of the rotating rod 227, the air outlet pipe 243 can continuously eject air, so that the polished part of the steel pipe can be blown, thereby increasing the pressure. Increasing the air flow rate can prevent the dust generated by grinding from adhering to the steel pipe and affecting the subsequent welding quality. The movable plate 230 can drive the connecting frame 245 to move back and forth during the reciprocating movement. After the connecting frame 245 moves back and forth, the meshing of the rack 246 and the rotating gear 247 can drive the air outlet pipe 243 to rotate back and forth on the cylinder 239, thereby expanding the blowing range of the air outlet pipe 243, expanding the cleaning range of the steel pipe, improving the cleaning quality, avoiding the smaller blowing range due to reducing the outlet diameter to ensure the flow rate, and improving practicality.
