At this time, the inner ring wheel 1005 is clamped in the annular groove 903 and rolls along the inner wall of the annular ring 901, so that the welding seat 10 cannot be separated from the welding ring 9 due to gravity.
The upper end of the welding seat shell 1002 is also provided with an automatic welding machine head 1003, and the welding seat shell 1002 is connected with the automatic welding machine head 1003 in a clamping mode, so that the automatic welding machine head 1003 can be replaced and maintained conveniently.
When the butt joint mechanism is used for butt joint of pipelines, firstly, the handle 310 rotates for a certain number of teeth to adjust the distance between the two fixed rollers 313 at the two ends of the butt joint mechanism, so that the outer surfaces of the two fixed rollers 313 at the two ends can be tangent to the outer surface of the butt joint pipe 6. And then the two fixing rollers 313 are lifted to the position tangent to the outer surface of the installed butt joint pipe through the first lifting mechanism 2 at one end of the butt joint mechanism, and the clamping fixing component 4 is adjusted to fix one end of the butt joint mechanism on the installed butt joint pipe. Then, the fixed roller 313 arranged at the other end of the docking mechanism is adjusted by the hand crank 310 to the same distance, and then a docking pipe 6 to be docked is hung at the other end of the docking mechanism, and the first lifting mechanism 2 at the other end of the docking mechanism is adjusted at the same time, so that the first lifting mechanisms 2 at the two ends of the docking mechanism are on the same horizontal line. Then, the two sets of first motors 204 are driven to adjust the clamping and fixing assemblies 4 at the two ends of the butting mechanism, so that the two sets of clamping and fixing assemblies 4 clamp the butting pipe 6. The other end of the docking mechanism is then driven by the second motor 205 to move the docking assembly moving seat 301 carrying the undocked docking tube 6 towards the fixed end of the docking mechanism until the nozzles of the docking tubes are fully fitted. Finally, by driving the third motor 1009, the soldering nest 10 makes a circular motion on the soldering ring 9 by the engagement of the fourth gear 1001 and the gear ring 901. At this time, the automatic welding machine head 1003 installed on the welding seat 10 can weld the joint of two butted joint pipes 6 when the welding seat 10 performs circular motion on the welding ring 9, and after the welding is finished, the clamping and fixing assembly 4 is loosened, the height of the first lifting mechanism 2 is adjusted, so that the butting mechanism is released from fixing and is fixed on the butted joint pipes again. The butt joint mechanism can repeat the steps to weld the joint of the butt joint pipe at the next section.
The butt joint mechanism has the advantages that the butt joint step is simple, the precision during butt joint is guaranteed, after the butt joint is finished, the butt joint assembly does not need to be repeatedly disassembled and assembled, the next section of butt joint pipe can be continuously butted, the working efficiency is improved, and a large amount of manpower is saved.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
