[0014] Beneficial effects of the present invention: 1. The welding auxiliary device for laying natural gas pipelines drives the motors at the positions of gears one and three. Under the action of meshing, the linkage frame and the linkage shaft move synchronously. The gasket will first touch the natural gas pipeline, and can play a buffering effect under the action of the elastic member one. When squeezed to a certain extent, the T seat contacts the switch, and the position of the welding head and the linkage frame stops. On the one hand, it ensures that the natural gas pipeline is in the center of the half hoop one and the half hoop two, and on the other hand, it ensures that the welding head can keep the same distance from the welding point when doing circular motion, so as to improve the welding effect of the natural gas pipeline, and the welding head can move to the corresponding position according to the natural gas pipelines of different diameters for welding; 2. The welding auxiliary device for laying natural gas pipelines introduces the fume generated by welding into the input chamber through the exhaust fan in the drainage bucket. Under the action of the rotor shape, the linkage cylinder and the gyroscopic seat will rotate. Under the action of its slope, the linkage cylinder enables a number of telescopic cylinders to be telescopically moved to different degrees, so as to achieve the control and purification of the fume in turn, ensuring that the corresponding telescopic cylinder is not used in the purification process during the process of removing pollutants on the grille screen 2, thereby ensuring the efficiency of fume purification and improving the effect of fume purification. 3. When the welding auxiliary device for laying natural gas pipelines moves through the telescopic cylinder, the lead screw will be linked to the thread sleeve to rotate. At this time, the dredging strip directly acts on the grid screen 2, so that the pollutants under the surface purification barrier can be removed. In this way, the grid screen 2 can maintain the original effect in the subsequent purification treatment, realize non-stop operation, and improve the purification treatment efficiency of smoke; 4. When the welding auxiliary device for laying natural gas pipelines touches the peak point of the slope of the telescopic cylinder and the linkage cylinder, the smoke enters the telescopic cylinder, and the lower position of the transfer cylinder changes to the position of the grid screen two. The incoming smoke will lead the raised particles and part of the mist to the back position of the grid screen one through the transfer cylinder. Under the action of the grid screen one itself, the mist can be purified and guided out, and the particles will remain on the back of the grid screen one, thereby ensuring the centralized treatment of the removed pollutants.

The transfer tube 315 telescopically moves in the transmission channel 1 330. The transmission channel 2 335 is reserved in the transfer tube 315. The lower position of the transfer tube 315 is forked. The elastic member 336 is arranged between the directional tube 314 and the upper inner edge of the output chamber 307.

[0044] When the peak positions of the slopes of the telescopic cylinder 326 and the linkage cylinder 312 touch each other, the grille screen 2 325 is fully exposed in the output chamber 307, and the lower position of the transfer cylinder 315 changes to the position of the grille screen 2 325. The lowest bending part of the transmission channel 2 335 corresponds to the position of the grille screen 2 325. At this time, the pollutants on the grille screen 2 325 can be transported to the back position of the grille screen 1 306 under the action of the transmission channel 2 335. When the telescopic cylinder 326 separates from the peak point of the slope of the linkage cylinder 312, the telescopic cylinder 326 can be pressed down under the action of the elastic member 336, so that it can always keep in contact with the slope of the linkage cylinder 312.

[0045] Embodiment 3, working principle: test and adjust the initial position of the welding head 208 in advance, connect the side mechanism and the middle mechanism to the natural gas pipeline to be welded, and after the half hoop 2 101 and the half hoop 1 100 are closed, the side mechanism and the middle mechanism form a ring, wherein the side of the half hoop 2 101 can be connected to the plug-in for use in the application environment of the temporary construction site, and the side of the half hoop 2 101 can also be installed with a base for use in the factory. At this time, the motor at the position of the drive gear 1 109 and the gear 3 206, at this time, the gear 1 109 and the gear 3 206 run synchronously, the linkage frame 103 and the linkage shaft 207 move synchronously, the gasket 106 will first touch the natural gas pipeline, and under the action of the elastic member 107, it can play a buffering effect, which can play a buffering effect on the natural gas pipeline When squeezed to a certain extent, the T seat 105 contacts the switch 108, and the position of the welding head 208 and the linkage frame 103 stops at this time. On the one hand, it ensures that the natural gas pipeline is in the center of the half hoop 100 and the half hoop 2 101, and on the other hand, it ensures that the welding head 208 can maintain the same distance from the welding point when doing circular motion, and the welding head 208 can move to the corresponding position according to the natural gas pipeline of different diameters for welding, and under the drive of the gear 205 and the guidance of the guide plate 209, the bearing platform 203 can drive the welding head 208 to do circular motion, and the natural gas pipeline is fully welded at this time. At this time, the half hoop 100, the half hoop 2 101, the folding pad 110, the semicircular stop 1 200 and the semicircular stop 2 201 will be welded. The position is closed, and the exhaust fan in the drainage bucket 302 introduces the smoke generated by welding into the input chamber 308. Under the action of the shape of the rotor 311, the linkage cylinder 312 and the gyroscopic seat 310 will rotate. Under the action of its slope, the linkage cylinder 312 allows a number of telescopic cylinders 326 to be telescopically moved to different degrees. The telescopic cylinder 326 touches the valley point of the linkage cylinder 312. At this position, the grille screen 2 325 on the telescopic cylinder 326 is fully extended into the directional channel 4 313. At this time, the smoke cannot be purified normally through this telescopic cylinder 326. When the linkage cylinder 312 continues to move, the telescopic cylinder 326 will be driven to telescope under the action of the slope of the linkage cylinder 312, so that the grille screen 2 325 is gradually exposed in the output chamber 307. The telescopic cylinder 326 can perform normal smoke purification and treatment work. At this time, the smoke in the input chamber 308 will enter the telescopic cylinder 326 under the action of the guide channel 2 327, and under the action of the grille screen 2 325, the smoke can be purified and reach the output chamber 307. When the telescopic cylinder 326 is telescopic, the lead screw 328 changes its position synchronously. At this time, the wire sleeve 319 will be driven to rotate. Under the action of the bearing column 320 and the linkage disk 317, the dredging strip 318 directly acts on the grille screen 2 325, so as to remove the pollutants under the purification barrier on its surface. When the slope peak position of the telescopic cylinder 326 and the linkage cylinder 312 touches, the grille screen 2 325 is fully exposed in the output chamber 307.At this time, the lower position of the transfer tube 315 changes to the position of the second grille screen 325, and the lowermost bend of the transmission channel 2 335 corresponds to the position of the second grille screen 325. The raised particles and part of the mist are guided to the back of the first grille screen 306 through the transfer tube 315. Under the action of the first grille screen 306 itself, the mist can be purified and guided out, and the particles will remain on the back of the first grille screen 306.
