[0014] The method for using the steel welding device for construction engineering includes the following steps: Step 1: The steel pipe welds are butt-jointed, and the push plate continues to slide toward the middle of the limit rod. This arrangement is conducive to improving the sliding stability of the push plate. The push plate drives the telescopic rod to stretch. At this time, the pulling spring is stretched and becomes longer, and the pulling force of the pulling spring on the push base increases. At this time, the extrusion force of the push base on the steel pipe body on the supporting trough increases; Step 2: The welding end of the steel pipe is fixed. When the welding ends of the two steel pipe bodies are in contact, the push plate continues to slide toward the middle of the limit rod. At this time, the push plate and the sliding sleeve on the limit rod are squeezed. The sliding sleeve is squeezed and drives the moving rod to squeeze the reset spring. At this time, the moving rod slides along the moving groove, and the moving rod drives the extrusion ring directly above to slide along the limit column toward the end close to the weld. The extrusion ring slides along the inner wall of the welding cover and the top cover. The movement of the extrusion ring drives the locking pieces at one end of the several locking telescopic rods to move toward the side wall of the steel pipe body and generate extrusion. At this time, the locking telescopic rod is squeezed and contracted, and the locking spring contracts to increase the clamping force of the locking piece on the side wall of the steel pipe body; Step 3: The auxiliary steel pipe rotates. When the steel pipe body is placed in the support slot, the gravity of the support slot drives the support base on the roller to slide downward, and the support base drives the connecting rod to press the extrusion spring downward along the sliding rod. When the push plate and the sliding sleeve on the limit rod are squeezed, the sliding sleeve drives the auxiliary ring at one end of the linkage rod to slide upward along the sliding rod. At this time, the auxiliary ring slides upward and squeezes the extrusion spring. Step 4: Adjust the welding process. Rotate the adjusting dial on the adjusting part to drive the adjusting rod to slide up and down along the fixed frame. At this time, the adjusting rod drives the welding gun to slide up and down along the weld. This setting is conducive to adjusting the distance between the welding gun and the weld.

[0015] The present invention has the following beneficial effects: (1) According to the present invention, when the device is used, the steel pipe to be welded is first placed in the support groove body, and then the driving motor is started. The output end of the driving motor rotates to drive the output shaft to rotate, and the output shaft rotates to drive the push plate to slide along the output shaft. At this time, the push plate squeezes the pressure spring along the output shaft, and the push plate slides along the middle of the joint part of the limit rod. The push plate drives the push base at one end of the telescopic rod to slide inward along the support groove body, and the push base drives the steel pipe body on the support groove body to slide inward along the support groove body. When the welding ends of the two steel pipe bodies are in contact, the push plate continues to slide toward the middle of the limit rod. This arrangement is conducive to improving the stability of the sliding of the push plate. The push plate drives the telescopic rod to be stretched. At this time, the pulling spring is stretched and lengthened, and the pulling force of the pulling spring on the push base is increased. At this time, the squeezing force of the push base on the steel pipe body on the support groove body is increased. This arrangement is conducive to increasing the squeezing force of the welding ends of the two steel pipe bodies, thereby reducing the weld between the two steel pipes and improving the stability of welding.

[0016] (2) The present invention provides a fixing portion. When the welding ends of the two steel pipe bodies are in contact, the push plate continues to slide toward the middle of the limit rod. At this time, the push plate and the sliding sleeve on the limit rod are squeezed. The sliding sleeve is squeezed and drives the moving rod to squeeze the reset spring. At this time, the moving rod slides along the moving groove. The moving rod drives the extrusion ring directly above to slide along the limit column toward the end close to the weld. The extrusion ring slides along the inner wall of the welding cover and the top cover. The movement of the extrusion ring drives the locking pieces at one end of the several locking telescopic rods to move toward the side wall of the steel pipe body and generate extrusion. At this time, the locking telescopic rod is squeezed and contracted. The locking spring contracts to cause the locking piece to press against the side wall of the steel pipe body. The clamping force is increased, and such an arrangement is beneficial to keeping the steel pipe body stable during welding. On the other hand, the rotation of the output shaft drives gear one to rotate, and gear one drives gear two to rotate along the inner walls of the welding cover and the top cover, and gear two drives the extrusion piece to rotate. Cooperating with the extrusion effect of the extrusion piece, the extrusion piece drives the steel pipe body inside the fixed part to rotate. Such an arrangement is beneficial to the closed-loop welding of the weld of the steel pipe body; when the moving rod drives the extrusion ring to slide along the inner walls of the welding cover and the top cover, the extrusion ring is beneficial to cleaning the welding slag on the inner walls of the welding cover and the top cover and discharging it along the moving groove, thereby ensuring that the rotating piece drives the steel pipe body to rotate stably, thereby improving the welding quality of the weld of the steel pipe body.

[0017] (3) The present invention provides a support part. When the steel pipe body is placed in the support groove body, the gravity of the support groove body drives the support base on the roller to slide downward, and the support base drives the connecting rod to press the extrusion spring downward along the sliding rod. When the push plate and the sliding sleeve on the limit rod are squeezed, the sliding sleeve drives the auxiliary ring at one end of the linkage rod to slide upward along the sliding rod. At this time, the auxiliary ring slides upward and squeezes the extrusion spring. This arrangement is conducive to increasing the squeezing force of the rolling element on the bottom of the steel pipe body, so that the end of the steel pipe body away from the welding end can rotate stably, which is conducive to the stable rotation of the steel pipe body, thereby ensuring the welding quality of the weld of the steel pipe body.

[0018] (4) The present invention sets a welding part, and drives the adjusting rod to slide up and down along the fixing frame by rotating the adjusting dial on the adjusting part. At this time, the adjusting rod drives the welding gun to slide up and down along the weld. This setting is conducive to adjusting the distance between the welding gun and the weld, so that the device can adapt to the welding of steel pipe bodies with different diameters, thereby improving the practicality of the welding device. In addition, the extrusion ring in the extrusion part slides, and the extrusion ring removes the welding slag on the inner wall of the welding cover and the top cover and discharges it along the moving groove. The welding slag is then discharged from the device through the slag discharge window at the bottom of the mounting table.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The adjusting member 41 includes a fixing frame 411 fixedly connected to the top of the mounting platform 111, a limiting frame 412 fixedly connected to the top of the fixing frame 411, an adjusting rod 413 slidably connected to the limiting frame 412, an adjusting dial 414 is arranged inside the limiting frame 412, and the adjusting dial 414 is rotatably connected to the thread on the adjusting rod 413; The welding part 42 includes a welding gun 421 fixedly connected to the bottom of the adjusting rod 413, and a slag discharge window 422 is provided at the bottom of the mounting platform 111. The function of the component is to set the welding part 4, and to drive the adjusting rod 413 to slide up and down along the fixing frame 411 by rotating the adjusting dial 414 on the adjusting part 41. At this time, the adjusting rod 413 drives the welding gun 421 to slide up and down along the weld. This arrangement is conducive to adjusting the distance between the welding gun 421 and the weld, so that the device can adapt to the welding of steel pipe bodies with different diameters, thereby improving the practicality of the welding device. In addition, the extrusion ring 326 in the extrusion part 32 slides, and the extrusion ring 326 removes the welding slag on the inner wall of the welding cover 311 and the top cover 312 and discharges it along the moving groove 324. The welding slag is then discharged from the device through the slag discharge window 422 at the bottom of the mounting platform 111.

[0033] The method for using the steel welding device for construction engineering includes the following steps: Step 1: The steel pipe welds are butt-jointed, and the push plate 131 continues to slide toward the middle of the limit rod 135. This arrangement is conducive to improving the sliding stability of the push plate 131. The push plate 131 drives the telescopic rod 132 to stretch. At this time, the pulling spring 134 is stretched and lengthened, and the pulling force of the pulling spring 134 on the pushing base 133 increases. At this time, the squeezing force of the pushing base 133 on the steel pipe body on the supporting groove body 114 increases; Step 2: The welding end of the steel pipe is fixed. When the welding ends of the two steel pipe bodies are in contact, the pushing plate 131 continues to slide toward the middle of the limiting rod 135. At this time, the pushing plate 131 is squeezed with the sliding sleeve 321 on the limiting rod 135. The sliding sleeve 321 is squeezed and drives the moving rod 323 to squeeze the reset spring 322. At this time, the moving rod 323 slides along the moving groove 324. The moving rod 323 drives the extrusion ring 326 just above to slide along the limiting column 325 toward the end close to the weld. The extrusion ring 326 slides along the inner wall of the welding cover 311 and the top cover 312. The movement of the extrusion ring 326 drives the locking pieces 334 at one end of the locking telescopic rods 332 to move toward the side wall of the steel pipe body and generate extrusion. At this time, the locking telescopic rod 332 is squeezed and contracted, and the locking spring 333 contracts to increase the clamping force of the locking piece 334 on the side wall of the steel pipe body. Step 3: The auxiliary steel pipe rotates. When the steel pipe body is placed into the support slot 114, the gravity of the support slot 114 drives the support base 222 on the roller 223 to slide downward, and the support base 222 drives the connecting rod 221 to press the extrusion spring 212 downward along the sliding rod 211. When the push plate 131 and the sliding sleeve 321 on the limit rod 135 are squeezed, the sliding sleeve 321 drives the auxiliary ring 342 at one end of the linkage rod 341 to slide upward along the sliding rod 211. At this time, the auxiliary ring 342 slides upward and squeezes the extrusion spring 212. Step 4: Adjust welding. The adjusting dial 414 on the rotating adjusting member 41 drives the adjusting rod 413 to slide up and down along the fixing frame 411. At this time, the adjusting rod 413 drives the welding gun 421 to slide up and down along the weld. This setting is conducive to adjusting the distance between the welding gun 421 and the weld.

This arrangement is conducive to improving the sliding stability of the pushing plate 131. The pushing plate 131 drives the telescopic rod 132 to stretch. At this time, the pulling spring 134 is stretched and becomes longer. The pulling force of the pulling spring 134 on the pushing base 133 increases. At this time, the squeezing force of the pushing base 133 on the steel pipe body on the supporting groove body 114 increases. This arrangement is conducive to increasing the squeezing force of the welding ends of the two steel pipe bodies, thereby reducing the weld between the two steel pipes and improving the stability of welding. By setting the fixing part 3, when the welding ends of the two steel pipe bodies are in contact, the pushing plate 131 continuously slides toward the middle of the limiting rod 135. At this time, the pushing plate 131 and the limiting rod 135 are in contact. The sliding sleeve 321 on the upper part is squeezed, and the sliding sleeve 321 is squeezed and drives the moving rod 323 to squeeze the reset spring 322. At this time, the moving rod 323 slides along the moving groove 324, and the moving rod 323 drives the extrusion ring 326 just above to slide along the limiting column 325 toward the end close to the weld. The extrusion ring 326 slides along the inner wall of the welding cover 311 and the top cover 312. The movement of the extrusion ring 326 drives the locking pieces 334 at one end of the locking telescopic rods 332 to move toward the side wall of the steel pipe body and produce extrusion. At this time, the locking telescopic rod 332 is squeezed and contracted, and the locking spring 333 contracts to increase the clamping force of the locking piece 334 on the side wall of the steel pipe body. This arrangement is conducive to keeping the steel pipe body stable during welding. On the other hand, the output shaft 122 rotates to drive the gear 1 313 to rotate, and the gear 1 313 drives the gear 2 314 to rotate along the inner walls of the welding cover 311 and the top cover 312, and the gear 2 314 drives the extrusion piece 32 to rotate. With the extrusion effect of the extrusion piece 32, the extrusion piece 32 drives the steel pipe body inside the fixing part 3 to rotate, and this arrangement is conducive to the closed-loop welding of the weld of the steel pipe body; when the moving rod 323 drives the extrusion ring 326 to slide along the inner walls of the welding cover 311 and the top cover 312, the extrusion ring 326 is conducive to cleaning the welding slag on the inner walls of the welding cover 311 and the top cover 312 and discharging it along the moving groove 324, thereby ensuring that the rotating piece 31 drives the steel pipe body to rotate stably, thereby improving the welding quality of the weld of the steel pipe body; By setting the support part 2, when the steel pipe body is placed in the support groove body 114, the gravity of the support groove body 114 drives the support base 222 on the roller 223 to slide downward, and the support base 222 drives the connecting rod 221 to press the extrusion spring 212 downward along the sliding rod 211. When the pushing plate 131 and the sliding sleeve 321 on the limiting rod 135 are squeezed, the sliding sleeve 321 drives the auxiliary ring 342 at one end of the linkage rod 341 to slide upward along the sliding rod 211. At this time, the auxiliary ring 342 slides upward and squeezes the extrusion spring 212. This arrangement is conducive to increasing the squeezing force of the rolling element 22 on the bottom of the steel pipe body, so that the end of the steel pipe body away from the welding end can rotate stably, which is conducive to the steel The pipe body rotates stably, thereby ensuring the welding quality of the weld of the steel pipe body; by setting the welding part 4, the adjusting dial 414 on the rotating adjusting member 41 drives the adjusting rod 413 to slide up and down along the fixing frame 411, and at this time the adjusting rod 413 drives the welding gun 421 to slide up and down along the weld, so that it is beneficial to adjust the distance between the welding gun 421 and the weld, so that the device is suitable for welding steel pipe bodies of different diameters, and the practicality of the welding device is improved.
