[0038] The welding part comprises a welding gun fixedly connected to the bottom of the adjusting rod, and a slag discharge window is provided at the bottom of the mounting platform.

[0039] The method for using the steel welding device for construction engineering includes the following steps:

[0040] 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;

[0041] 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;

[0042] 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.

[0043] Step 4: Adjust the welding. By rotating the adjustment turntable on the adjustment member, the adjustment rod is driven to slide up and down along the fixed frame. At this time, the adjustment rod drives the welding torch to slide up and down along the weld. This setting is beneficial to adjusting the distance between the welding torch and the weld.

[0044] The present invention has the following beneficial effects:

[0045] (1). In the present invention, when using the device, first place the steel pipe to be welded inside the support trough. At this time, start the driving motor. The output end of the driving motor rotates to drive the output rotating shaft to rotate. The output rotating shaft rotates to drive the pushing plate to slide along the output rotating shaft. At this time, the pushing plate squeezes the pressure spring along the output rotating shaft. The pushing plate slides along the middle part of the docking part of the limiting rod. The pushing plate drives the pushing base at one end of the pulling telescopic rod to slide inward along the support trough. The pushing base drives the steel pipe body on the support trough to slide inward along the support trough. When the welding ends of the two steel pipe bodies come into contact, the pushing plate continues to slide toward the middle of the limiting rod. This setting is beneficial to improving the stability of the sliding of the pushing plate. The pushing plate drives the pulling telescopic rod to stretch. At this time, the pulling spring is stretched and becomes longer. The pulling force of the pulling spring on the pushing base increases. At this time, the extrusion force of the pushing base on the steel pipe body on the support trough increases. This setting is beneficial to increasing the extrusion force at the welding ends of the two steel pipe bodies, thereby reducing the weld between the two steel pipes and improving the welding stability.

[0046] (2). In the present invention, by setting the fixing part, when the welding ends of the two steel pipe bodies come into contact, the pushing plate continues to slide toward the middle of the limiting rod. At this time, the pushing plate squeezes the sliding sleeve on the limiting rod. The sliding sleeve is squeezed to drive the moving rod to squeeze the return spring. At this time, the moving rod slides along the moving groove. The moving rod drives the extrusion ring directly above to slide toward the end close to the weld along the limiting column. The extrusion ring slides along the inner walls of the welding cover and the top cover. The movement of the extrusion ring drives the locking pieces at one end of several locking telescopic rods to move toward the side wall of the steel pipe body and generate extrusion. At this time, the locking telescopic rods are squeezed and contracted. The locking spring contracts to increase the clamping force of the locking piece on the side wall of the steel pipe body. This setting is beneficial to keeping the steel pipe body stable during welding. On the other hand, the output rotating shaft rotates to drive the first gear to rotate. The first gear drives the second gear to rotate along the inner walls of the welding cover and the top cover. The second gear drives the extrusion member to rotate. With the extrusion action of the extrusion member, the extrusion member drives the steel pipe body inside the fixing part to rotate. This setting 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 member drives the steel pipe body to rotate stably, and thus improving the welding quality of the weld of the steel pipe body.

[0047] (3). In the present invention, by providing a support portion, when the steel pipe body is placed inside 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 squeeze the compression spring downward along the sliding rod. When the pushing plate squeezes against the sliding sleeve on the limiting rod, 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 upward sliding of the auxiliary ring generates extrusion with the compression spring. This setting is beneficial to increasing the extrusion force of the rolling members on the bottom of the steel pipe body, so that the end of the steel pipe body far from the welding end rotates stably, which is beneficial to the stable rotation of the steel pipe body, and thus ensures the welding quality of the weld of the steel pipe body.

[0048] (4). In the present invention, by providing a welding portion, the adjustment turntable on the rotation adjustment member drives the adjustment rod to slide up and down along the fixed frame. At this time, the adjustment rod drives the welding torch to slide up and down along the weld. This setting is beneficial to adjusting the distance between the welding torch and the weld, which is beneficial to the device adapting to the welding of steel pipe bodies with different pipe diameters, improving the practicability of the welding device. In addition, through the sliding of the extrusion ring in the extrusion member, 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, and the welding slag is then discharged from the slag discharge window at the bottom of the installation table of the device.

[0049] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

The function of this component is that by setting the fixing part 3, when the welding ends of the two steel pipe bodies come into contact, the pushing plate 131 continuously slides towards the middle of the limiting rod 135. At this time, the pushing plate 131 squeezes the sliding sleeve 321 on the limiting rod 135. The sliding sleeve 321 is squeezed and drives the moving rod 323 to squeeze the return spring 322. At this time, the moving rod 323 slides along the moving groove 324. The moving rod 323 drives the extrusion ring 326 directly above it to slide along the limiting column 325 towards the end close to the weld. The extrusion ring 326 slides along the inner walls 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 a number of locking telescopic rods 332 to move towards the side wall of the steel pipe body and generate extrusion. At this time, the locking telescopic rods 332 are squeezed and contracted, and the locking springs 333 contract to increase the clamping force of the locking pieces 334 on the side wall of the steel pipe body. Such a setting is beneficial to keeping the steel pipe body stable during welding. On the other hand, the output rotating shaft 122 rotates to drive the first gear 313 to rotate. The first gear 313 drives the second gear 314 to rotate along the inner walls of the welding cover 311 and the top cover 312. The second gear 314 drives the extrusion part 32 to rotate. With the extrusion action of the extrusion part 32, the extrusion part 32 drives the steel pipe body inside the fixing part 3 to rotate. Such a setting is beneficial 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 beneficial 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, so as to ensure that the rotating part 31 drives the steel pipe body to rotate stably, thereby improving the welding quality of the weld of the steel pipe body.

[0091] The welding part 4 includes:

[0092] The adjusting part 41, the adjusting part 41 is installed directly above the installation table 111, and the adjusting part 41 is used to adjust the welding distance;

[0093] The welding part 42, the welding part 42 is arranged directly below the adjusting part 41, and the welding part 42 is used to weld the weld of the steel pipe body;

[0094] Among them, the adjusting part 41 is used to adjust the distance between the welding part 42 and the weld of the steel pipe body.

[0095] The adjusting part 41, the adjusting part 41 includes a fixing frame 411 fixedly connected to the top of the installation table 111. The top of the fixing frame 411 is fixedly connected with a limiting frame 412. A adjusting rod 413 is slidably connected to the limiting frame 412. An adjusting turntable 414 is arranged inside the limiting frame 412. The adjusting turntable 414 is rotationally connected to the thread on the adjusting rod 413;

[0096] 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.

[0097] The method for using the steel welding device for construction engineering includes the following steps:

[0098] 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;

[0099] 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.

[0100] Step 3: Assist the steel pipe to rotate. When the steel pipe body is placed inside the support groove 114, the gravity of the support groove 114 drives the support base 222 on the roller 223 to slide downward. The support base 222 drives the connecting rod 221 to squeeze the compression spring 212 downward along the sliding rod 211. When the push plate 131 squeezes the sliding sleeve 321 on the limiting rod 135, 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 compression spring 212;

[0101] Step 4: Adjust the welding. By rotating the adjustment turntable 414 on the adjusting member 41, the adjusting rod 413 is driven to slide up and down along the fixed frame 411. At this time, the adjusting rod 413 drives the welding torch 421 to slide up and down along the weld seam. Such a setting is beneficial to adjusting the distance between the welding torch 421 and the weld seam.

[0102] A specific application of this embodiment is:

[0103] When using this device, first place the steel pipe to be welded inside the support trough 114. At this time, start the driving motor 121. The output end of the driving motor 121 rotates to drive the output rotating shaft 122 to rotate. The rotation of the output rotating shaft 122 drives the pushing plate 131 to slide along the output rotating shaft 122. At this time, the pushing plate 131 squeezes the compression spring 136 along the output rotating shaft 122. The pushing plate 131 slides along the middle part of the docking part 1 of the limiting rod 135. The pushing plate 131 drives the pushing base 133 at one end of the pulling telescopic rod 132 to slide inward along the support trough 114. The pushing base 133 drives the steel pipe body on the support trough 114 to slide inward along the support trough 114. When the welding ends of the two steel pipe bodies come into contact, the pushing plate 131 continues to slide towards the middle of the limiting rod 135. This setting is beneficial to improving the sliding stability of the pushing plate 131. The pushing plate 131 drives the pulling telescopic rod 132 to produce stretching. 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 extrusion force of the pushing base 133 on the steel pipe body on the support trough 114 increases. This setting is beneficial to increasing the extrusion force at the welding ends of the two steel pipe bodies, thereby reducing the weld seam between the two steel pipes and improving the welding stability; by setting the fixing part 3, when the welding ends of the two steel pipe bodies come into contact, the pushing plate 131 continues to slide towards the middle of the limiting rod 135. At this time, the pushing plate 131 squeezes the sliding sleeve 321 on the limiting rod 135. The sliding sleeve 321 is squeezed to drive the moving rod 323 to squeeze the return spring 322. At this time, the moving rod 323 slides along the moving groove 324. The moving rod 323 drives the extrusion ring 326 directly above it to slide towards the end close to the weld along the limiting column 325. The extrusion ring 326 slides along the inner walls 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 a number of locking telescopic rods 332 to move towards the side wall of the steel pipe body and produce extrusion. At this time, the locking telescopic rods 332 are squeezed and contracted. The contraction of the locking spring 333 increases the clamping force of the locking pieces 334 on the side wall of the steel pipe body. This setting is beneficial to keeping the steel pipe body stable during welding. On the other hand, the rotation of the output rotating shaft 122 drives the first gear 313 to rotate. The first gear 313 drives the second gear 314 to rotate along the inner walls of the welding cover 311 and the top cover 312. The second gear 314 drives the extrusion part 32 to rotate. With the extrusion action of the extrusion part 32, the extrusion part 32 drives the steel pipe body inside the fixing part 3 to rotate. This setting is beneficial to the closed-loop welding of the weld seam 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 beneficial 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 the stable rotation of the rotating part 31 driving the steel pipe body, and thus improving the welding quality of the weld seam of the steel pipe body;

[0104] By setting the supporting part 2, when the steel pipe body is placed inside the supporting groove body 114, the gravity of the supporting groove body 114 drives the supporting base 222 on the roller 223 to slide downward. The supporting base 222 drives the connecting rod 221 to squeeze the compression spring 212 downward along the sliding rod 211. When the pushing plate 131 squeezes against the sliding sleeve 321 on the limiting rod 135, 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 upward sliding of the auxiliary ring 342 generates extrusion with the compression spring 212. Such a setting is beneficial to increasing the extrusion force of the rolling member 22 on the bottom of the steel pipe body, so that the end of the steel pipe body far from the welding end rotates stably, which is beneficial to the stable rotation of the steel pipe body, and thus ensures the welding quality of the weld of the steel pipe body; by setting the welding part 4, the adjusting turntable 414 on the rotation adjusting part 41 drives the adjusting rod 413 to slide up and down along the fixed frame 411. At this time, the adjusting rod 413 drives the welding torch 421 to slide up and down along the weld. Such a setting is beneficial to adjusting the distance between the welding torch 421 and the weld, which is beneficial to the device to adapt to the welding of steel pipe bodies with different pipe diameters, improving the practicability of the welding device. In addition, through the sliding of the extrusion ring 326 in the extrusion part 32, the extrusion ring 326 removes the welding slag on the inner walls 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 installation table 111.
