step 4, when the Christmas tree pipeline is maintained, the bayonet lock (512) is lifted upwards, and the bayonet lock (512) is separated from the positioning groove;
step 4-1, moving the position of the support rod (56) on the guide rail (511) according to the position of the maintained Christmas tree pipeline;
step 4-2, after the supporting rod (56) moves to the designated position, the bayonet lock (512) is put down, and the lower end of the bayonet lock (512) is clamped into the positioning groove again under the action of gravity;
step 4-3, the maintenance personnel sit on the stool (52), pull out the locking pin (551), and press the stool (52) by the buttocks;
step 4-4, the stool (52) is pressed downwards to drive the hollow pipe (53) to move downwards, the hollow pipe (53) moves downwards to drive the tension spring (57) to stretch, the stool (52) is pressed downwards to the designated sitting posture height and is inserted into the locking pin (551) again, the locking pin (551) is inserted into the clamping groove on the adjusting tooth, the supporting rod (56) is locked relative to the hollow pipe (53), and the stool (52) is locked;
step 5, after the Christmas tree pipeline is maintained, the locking pin (551) is pulled out again, the hollow pipe (53) moves upwards to reset under the action of the tension spring (57), and the stool (52) resets;
step 6, then rotating the adjusting bolt (21) on the adjusting plate (22) again until the level meter (23) displays level;
step 7, when the Christmas tree pipeline is disassembled, the hoop on the pipeline is separated from the mounting plate (33), and the pipeline is carefully placed on the guide wheel (43);
7-1, electrifying the linear motor (45) again, driving a rotor of the linear motor (45) to drive the hydraulic telescopic arm (42) to move along the guide groove (41) until the pipeline position is completely staggered with the mounting plate (33), and stopping the linear motor (45) after power failure;
and 7-2, introducing a hydraulic source into the hydraulic telescopic arm (42), contracting the hydraulic telescopic arm (42), driving the pipeline to descend until the pipeline reaches the lowest end, stopping the hydraulic telescopic arm (42), and moving the pipeline away through an external transfer device.
