After the welded pipe is compressed, the welded pipe is continued to be conveyed forward, and the joints of the slightly bent welded pipes can be corrected. The welded pipe is conveyed until the joints of the two welded pipes are aligned, and then a welding gun is used to weld the joints for splicing.

[0013] A positioning method for a processing positioning device of a steel structure welded pipe comprises the following steps:

[0014] S1: Start the motor to rotate, drive the rotating rod on the right side to rotate, and make the conveyor wheel rotate. The rotating rod on the right side will also drive the pulley to rotate, and then the pulley on the left side will rotate through the belt transmission;

[0015] S2: driving the rotating rod 2 to rotate, causing the gear 1 to rotate, thereby driving the gear 2 to rotate, causing the rotating rod 1 on the left to rotate, and driving the conveying wheel on the left to rotate;

[0016] S3: Start the electric telescopic rod to extend, so that the compression sleeve at the top descends close to the compression sleeve at the bottom. The descent of the compression sleeve at the top drives the sliding rod to descend, and the descent of the sliding rod drives the compression sleeve on the left side to descend through the connecting rod.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention utilizes the force of the motor rotation to drive the right rotating rod 1 to rotate, so that the conveying wheel rotates. The rotation of the right rotating rod 1 also drives the pulley to rotate, and then drives the pulley on the left side to rotate through the belt transmission, drives the rotating rod 2 to rotate, so that the gear 1 rotates, thereby drives the gear 2 to rotate, so that the rotating rod 1 on the left side rotates, drives the conveying wheel on the left side to rotate, so that the conveying wheels on both sides rotate in opposite directions, so that the conveyed welding pipes are close to each other, and then the electric telescopic rod is started to extend, so that the compression sleeve at the top is lowered and close to the compression sleeve at the bottom. The descent of the compression sleeve at the top drives the sliding rod to descend. The descent of the sliding rod drives the compression sleeve on the left side to descend through the connecting rod 1, and can also drive the rotating rod 1 at the top to descend through the connecting rod 2, so that the two conveying wheels squeeze the welding pipe to prevent the welding pipe from slipping during transportation. When the welding pipe is conveyed When it enters the compression sleeve, the two compression sleeves cooperate with each other to compress the welded pipe. The welded pipe will first contact the elastic sleeve, causing the elastic sleeve to be squeezed and displaced. When the elastic sleeve moves, it will drive the connecting rod to move, causing the extrusion ring to squeeze the compressed spring and accumulate elastic potential energy until the welded pipe is compressed. After the welded pipe is compressed, the welded pipe is continued to be transported forward, and the joints of the slightly bent welded pipes can be corrected. The welded pipe is transported until the joints of the two welded pipes are aligned, and then a welding gun is used to weld the joints for splicing. The elastic supporting force applied to the welded pipe correction through the elastic sleeve helps the welded pipe to be subjected to a more balanced force during the extrusion process, reducing the possibility of local deformation, thereby helping the welded pipe to gradually become straighter. The corrected welded pipe is also easier to align to avoid dislocation, and can complete rapid positioning, which is conducive to batch splicing and processing of welded pipes.

[0019] (2) The present invention utilizes the downward force of the sliding rod to drive the elastic rod to descend, so that the elastic rod moves in the U-shaped sleeve, and the other side rises to lift the lifting frame. The rising of the lifting frame will drive the piston rod to rise, squeeze the gas inside the compressor, and transport the squeezed gas to the connecting cylinder through the compressor, and then discharge the gas to the surface of the elastic sleeve through the gas pipe, thereby accelerating the decrease in the surface temperature of the elastic sleeve. This solves the problem that when batches of welded pipes are spliced, the heat received by the welded pipes during welding is conducted to the elastic sleeve, resulting in an increase in the temperature of the elastic sleeve. By accelerating the temperature drop of the elastic sleeve, the temperature of the elastic sleeve is prevented from being too high, which increases the friction when contacting the welded pipe, and requires a greater clamping force to transport the welded pipe, resulting in a greater possibility of deformation of the welded pipe, which helps to maintain a good correction effect.

[0020] (3) The present invention utilizes the force of the piston rod 1 rising. Since the side of the piston rod 2 close to the piston rod 1 is an inclined surface, when the piston rod 1 rises, it will smoothly push the piston rod 2 to move, compressing the gas inside the compressed air pipe. The movement of the piston rod 2 will stretch the tension spring 1, so that the tension spring 1 accumulates resilience. The compressed gas is transported through the compressed air pipe and then collected through the gas collecting pipe, so that the gas enters the arc-shaped air bag, causing the arc-shaped air bag to expand, driving the friction plate to move close to the welding pipe. Relying on the expansion of the arc-shaped air bag, the friction plate can fit tightly with the welding pipe. When the welding pipe is transported, the friction plate removes dust on the surface of the welding pipe to avoid frequent contact between the elastic sleeve and the welding pipe, resulting in too much dust accumulating on the surface of the elastic sleeve. The dust distribution must be uneven, which affects the elastic sleeve when correcting the welding pipe. The extrusion force is uneven, affecting the correction of the welding pipe.

[0021] (4) The present invention utilizes the force of the expansion of the arc-shaped airbag to push the connecting shaft 1 to move, thereby driving the connecting block to move. The movement of the connecting block will stretch the stretching spring 2, so that the stretching spring 2 accumulates rebound force. The movement of the connecting block will also drive the connecting shaft 2 to move. The movement of the connecting shaft 2 separates the cleaning plate from the friction plate, thereby avoiding affecting the cleaning dust of the friction plate. When the piston rod 1 descends, the squeezing force on the piston rod 2 disappears, and the piston rod 2 is reset by the rebound force of the stretching spring 1, so that the gas in the arc-shaped airbag is discharged and reset. The rebound force of the stretching spring 2 is used to reset the connecting block, thereby driving the cleaning plate to scrape and clean the dust adhered to the surface of the friction plate and drop it into the collection box. By cleaning the dust adhered to the friction plate, the service life of the friction plate can be extended, and a good friction effect can be maintained. The dust cleaning effect on the welded pipe can be maintained, thereby avoiding frequent replacement of the friction plate and affecting the efficiency of batch processing of welded pipes.

[0040] For example 2, please refer to Figure 4 - Fig. 9The present invention is a processing and positioning device for a steel structure welded pipe. On the basis of the first embodiment, the correction mechanism 2 also includes a plurality of fixed cylinders 204 fixedly connected to the outer wall of the compression sleeve 202. The parts contained in the plurality of fixed cylinders 204 are the same. A connecting rod 206 is slidably connected to the inner wall of the fixed cylinder 204. The side wall of the connecting rod 206 is fixedly connected to the outer wall of the elastic sleeve 203. An extrusion ring 205 is slidably connected to the inner wall of the fixed cylinder 204. The inner wall of the extrusion ring 205 is fixedly connected to the outer wall of the connecting rod 206. The connecting rod 206 is fixedly connected, and a compression spring 207 is sleeved on the outer wall of the connecting rod 206. The electric telescopic rod 114 is started to extend, so that the compression sleeve 202 at the top is lowered close to the compression sleeve 202 at the bottom.

The rotation of the rotating rod 105 on the right side also drives the pulley 107 to rotate, and then the pulley 107 on the left side rotates through the belt 108;

[0046] S2: driving the second rotating rod 109 to rotate, so that the gear 110 rotates, thereby driving the second gear 111 to rotate, so that the rotating rod 105 on the left side rotates, and driving the conveying wheel 106 on the left side to rotate;

[0047] S3: Start the electric telescopic rod 114 to extend, so that the compression sleeve 202 at the top descends close to the compression sleeve 202 at the bottom. The descent of the compression sleeve 202 at the top drives the sliding rod 115 to descend, and the descent of the sliding rod 115 drives the compression sleeve 202 on the left side to descend through the connecting rod 116.

[0048] A specific application of this embodiment is as follows: when the present invention is used, the welded pipes to be spliced ​​are passed through between the conveying wheels 106 on both sides, and then the motor 104 is started to drive the rotating rod 105 on the right side to rotate, so that the conveying wheel 106 rotates. The rotation of the rotating rod 105 on the right side also drives the pulley 107 to rotate, and then the belt 108 drives the pulley 107 on the left side to rotate, and drives the rotating rod 2 109 to rotate, so that the gear 110 rotates, thereby driving the gear 2 111 to rotate, so that the rotating rod 105 on the left side rotates, and drives the conveying wheel 106 on the left side to rotate, so that the conveying wheels 106 on both sides rotate in opposite directions, so that the conveyed welded pipes are close to each other, and then the electric telescopic rod 114 is started to extend, so that The compression sleeve 202 at the top descends to approach the compression sleeve 202 at the bottom. The descent of the compression sleeve 202 at the top will drive the sliding rod 115 to descend. The descent of the sliding rod 115 drives the compression sleeve 202 on the left side to descend through the connecting rod 116, and can also drive the rotating rod 105 at the top to descend through the connecting rod 117, so that the two conveying wheels 106 squeeze the welded pipe to prevent the welded pipe from slipping during transportation. When the welded pipe is conveyed into the compression sleeve 202, the two compression sleeves 202 cooperate with each other to compress the welded pipe. The welded pipe will first contact the elastic sleeve 203, so that the elastic sleeve 203 is squeezed and displaced. When the elastic sleeve 203 moves, it will drive the connecting rod 206 to move, so that the extrusion ring 205 squeezes the compressed spring 207, accumulating The elastic potential energy is used until the welded pipe is pressed tightly. After the welded pipe is pressed tightly, the welded pipe is continued to be conveyed forward. The joints of the welded pipes that are slightly bent can be corrected. The welded pipe is conveyed until the joints of the two welded pipes are aligned. Then the welding gun 102 is used to weld the joints for splicing. The elastic supporting force applied to the welded pipe correction through the elastic sleeve 203 helps the welded pipe to be subjected to a more balanced force during the extrusion process, reducing the possibility of local deformation, thereby helping the welded pipe to gradually become straighter. The corrected welded pipe is also easier to align and avoid misalignment. Rapid positioning can be completed, which is helpful for batch splicing of welded pipes. The downward force of the sliding rod 115 is used to drive the elastic rod 211 to descend, so that the elastic rod 211 moves in the U-shaped sleeve 210, so that the other side Lift the lifting frame 209, and the lifting of the lifting frame 209 will drive the piston rod 212 to rise, squeeze the gas inside the air cylinder 208, and transmit the squeezed gas to the connecting air cylinder 213 through the air cylinder 208, and then discharge the gas to the surface of the elastic sleeve 203 through the air pipe 214, so as to accelerate the decrease of the surface temperature of the elastic sleeve 203, solve the problem that when batches of welded pipes are spliced, the heat received by the welded pipes during welding is conducted to the elastic sleeve 203, resulting in an increase in the temperature of the elastic sleeve 203, and accelerate the temperature drop of the elastic sleeve 203 to avoid the temperature of the elastic sleeve 203 being too high, increase the friction when contacting with the welded pipe, need to apply a greater pressing force to transport the welded pipe, resulting in a greater possibility of deformation of the welded pipe, which helps to maintain a good correction effect;

[0049] Using the force of the piston rod 1 212 rising, since the side of the piston rod 2 303 close to the piston rod 1 212 is an inclined surface, when the piston rod 1 212 rises, it will smoothly push the piston rod 2 303 to move, compressing the gas inside the compressed air pipe 301. The movement of the piston rod 2 303 will stretch the tension spring 1 304, so that the tension spring 1 304 accumulates resilience. The compressed gas is transported through the compressed air pipe 301 and then collected by the gas collecting pipe 305, so that the gas enters the arc-shaped airbag 307, making the arc-shaped airbag 307 The airbag 307 expands, driving the friction plate 308 to move closer to the weld pipe. The arc-shaped airbag 307 expands, so that the friction plate 308 can fit closely with the weld pipe. When the weld pipe is transported, the friction plate 308 removes dust on the surface of the weld pipe to avoid frequent contact between the elastic sleeve 203 and the weld pipe, which causes too much dust to accumulate on the surface of the elastic sleeve 203. The dust distribution must be uneven, which affects the elastic sleeve 203 when correcting the weld pipe. The squeezing force is uneven, which affects the correction of the weld pipe. The arc-shaped airbag 307 expands. The expansion force pushes the connecting shaft 1 310 to move, driving the connecting block 311 to move. The movement of the connecting block 311 will stretch the stretch spring 2 312, so that the stretch spring 2 312 accumulates resilience. The movement of the connecting block 311 will also drive the connecting shaft 2 313 to move. The movement of the connecting shaft 2 313 separates the cleaning plate 309 from the friction plate 308 to avoid affecting the cleaning of the friction plate 308. When the piston rod 1 212 descends, the squeezing force on the piston rod 2 303 disappears, and the stretch spring 1 304 The rebound force of the second piston rod 303 resets the piston rod, discharges the gas in the arc-shaped airbag 307, and resets it. The rebound force of the second tension spring 312 resets the connecting block 311, drives the cleaning plate 309 to scrape and clean the dust adhering to the surface of the friction plate 308, and the dust falls into the collection box 118. By cleaning the dust adhering to the friction plate 308, the service life of the friction plate 308 can be extended, and a good friction effect can be maintained, thereby avoiding frequent replacement of the friction plate 308, which affects the efficiency of batch processing of welded pipes.
