the first step is as follows: through the symmetrical design around the device, make coupling mechanism 4 symmetry exist in the both ends mouth department of steel pipe 2 simultaneously, and carry out horizontal fixed with steel pipe 2 from both ends simultaneously, thereby make the center pin of steel pipe 2 and the well core rod 106 of both sides be in same department, through carrying out horizontal support with steel pipe 2, guarantee the level of steel pipe 2 and settle, thereby can effectually avoid the dislocation in the connection process, fix it from steel pipe 2's both ends in addition, can make the more firm that steel pipe 2 connects, thereby the connection steadiness of device has been improved.
The second step: through the existence of coupling mechanism 4, thereby make four even mortgages of connecting arc board 404 on the coupling mechanism 4 on the inside wall of steel pipe 2, make the center of coupling mechanism 4 and the center of steel pipe 2 remain unanimous all the time like this, thereby through the connection to steel pipe 2, thereby the accurate center that makes steel pipe 2 is in same line with well core rod 106, through such connected mode, thereby make the device when connecting the steel pipe 2 of different grade type, homoenergetic guarantee well core rod 106 and keep unanimous rather than the center, the operation of needing to look for center department in addition has been deleted, thereby make the connection of device and the welding in later stage can both confirm according to steel pipe 2's self, great improvement the flexibility and the accuracy of device.
The third step: through the cooperation of the connecting mechanism 4 and the synchronizing mechanism 5, due to the meshing of the meshing protrusion 506 and the meshing groove 405, when the first synchronizing disk 501 drives the second synchronizing disk 504 to rotate through the clamping column 503, the position between the meshing groove 405 and the meshing protrusion 506 can be controlled, so that the connecting column 403 can adjust the length extending out of the inside of the connecting groove 402, so that the connecting arc plate 404 can be better contacted and abutted against the inner side wall of the steel pipe 2, through the threaded connection of the first synchronizing disk 501 and the central rod 106, so that the rotation of the first synchronizing disk 501 is more accurate, when the first synchronizing disk 501 is rotated to drive the second synchronizing disk 504 to rotate, the connecting mechanism 4 and the steel pipe 2 can be synchronously adjusted to be connected, and the position of the connecting arc plate 404 is connected through synchronous adjustment, so that the length of the connecting column 403 extending out of the connecting groove 402 is the same, and the center of the device and the center of the steel pipe 2 can be always consistent, thereby making the connection of the device faster while assisting in consistent stabilization of the center.
The fourth step: through docking mechanism 7's existence, make the both ends outside that the ring flange 3 is in steel pipe 2 is got to positive clamp 713 clamp, after positive clamp 713 presss from both sides to get the ring flange 3, through not hard up handle 704 in the outside, thereby can make docking mechanism 7 whole through removing cup joint of pipe 701 and center rod 106 remove in the outside of center rod 106, thereby can press from both sides ring flange 3 and confirm ring flange 3 and steel pipe 2's final position through docking mechanism 7 clamp, through the setting of the scale 107 in the center rod 106 outside, thereby can effectually carry out accurate regulation to the position that ring flange 3 located, the bilateral symmetry of cooperation device simultaneously can also make the ring flange 3 position of both sides contrast through the existence of scale 107, thereby make ring flange 3 and steel pipe 2's connection more regularization.
The fifth step: through removing the connection of pipe 701 and center pole 106, thereby can make docking mechanism 7 drive the ring flange 3 and stabilize in the suitable position in steel pipe 2 side as required, thereby make the device can adjust the position of the connection of ring flange 3 and steel pipe 2 as required, simultaneously on coupling mechanism 4 and ring flange 3's connection problem, the device also can stretch out the length in connecting groove 402 through adjusting spliced pole 403 and carry out the fixed between the above-mentioned part, through the reality of device, thereby make the adjustable ability of device promote.
And a sixth step: the centers of the central rod 106 and the flange plate 3 are positioned at the same position through the stabilization of the connecting mechanism 4 and the synchronizing mechanism 5 and the steel pipe 2, then the flange plate 3 is positioned and butted through the butting mechanism 7 at the outer side of the central rod 106, the centers of the flange plate 3 and the steel pipe 2 are positioned at the same position during butting, in addition, the righting clamps 713 are clamped at the outer side of the flange plate 3 through the refining stages of the butting mechanism 7 and the flange plate 3, the righting clamps 713 existing at the periphery are all clamped at the outer side of the flange plate 3, so that the verticality between the flange plate 3 and the centers is ensured, the connection adaptability between the flange plate 3 and the steel pipe 2 is ensured in the butting and connecting processes, the right alignment of the flange plate 3 can be effectively controlled in the connecting process, and the connection right alignment between the flange plate 3 and the steel pipe 2 is improved, the welding quality of the device is improved.
The seventh step: design through heating ring 104, thereby after the location connection is accomplished between ring flange 3 and steel pipe 2, through moving connecting rod 103 in kerve 102, thereby make connecting rod 103 control heating ring 104 move the junction of ring flange 3 and steel pipe 2, thereby carry out the auxiliary heating, help welding between steel pipe 2 and the ring flange 3, and heating ring 104 presents the loop configuration, can be disposable weld the junction of ring flange 3 and steel pipe 2, thereby make supplementary welding effectual, the welding efficiency of device has been improved.
Eighth step: through the design of device with respectively with steel pipe 2 and flange 3's butt joint to make the middle part position space of steel pipe 2 and flange 3 big, thereby in later stage manual operation, make artifical operatable welding space big, make things convenient for the manual work to weld or follow-up operation, provide the space for the cooperation between device and the manual work, improved the use comfort of device.
The ninth step: through the existence of heating ring 104, before the connection of coupling mechanism 4 and steel pipe 2, can settle steel pipe 2 between heating ring 104 earlier, thereby make heating ring 104 play lapped effect, connect steel pipe 2 through follow-up lazytongs 5 and coupling mechanism 4, thereby make the connection of device more convenient, when the welding is accomplished and is dismantled, heating ring 104 plays lapped effect equally behind lazytongs 2 steel pipe at lazytongs 5 and coupling mechanism 4, thereby be convenient for the connection operation of device, make the cooperation degree between the device mechanism inseparable, the linkage of device has been improved.
