[0033] A regulating frame 39 is fixedly installed at the middle part of the top end of the frame body 1, and the top of the transmission shaft rod 18 movably penetrates and extends into the interior of the regulating frame 39. A regulating shaft rod 40 is rotatably installed in the interior of the regulating frame 39, and both ends of the regulating shaft rod 40 extend to the outside of the regulating frame 39. A regulating block 41 is fixedly installed at one end of the regulating shaft rod 40.

A circular stop block 46 is fixedly installed at the end of the regulating shaft rod 40 away from the regulating block 41. Through the interaction of the regulating thread 44, the locking nut 45 and the circular stop block 46, it can make the regulating and positioning assembly 5 achieve better stability after the positioning operation, so as to ensure that the pipeline can be stably positioned.

[0034] Working principle: During operation, first, install and fix the mounting bracket 2 with mounting bolts that are adapted to the diameter of the mounting hole 3. Then, insert the pipeline into the interior of the frame body 1 and make the pipeline sit on the top interior of the arc-shaped support seat 7. Then, loosen the locking nut 45 to release the positioning of the adjusting shaft rod 40, and then rotate the adjusting block 41 to drive the adjusting shaft rod 40 to rotate. The adjusting shaft rod 40 drives the adjusting bevel gear 42 to rotate, the adjusting bevel gear 42 drives the driving bevel gear 43 to rotate, and the driving bevel gear 43 drives the transmission shaft rod 18 to rotate inside the positioning bearing 28 and the support shaft seat 27, which can ensure better stability when the transmission shaft rod 18 rotates. At the same time, the transmission shaft rod 18 drives the transmission gear 19 to rotate, the transmission gear 19 drives the transmission rack 20 to move, the transmission rack 20 drives the positioning sliding sleeve 29 to slide on the outside of the positioning slide rod 30, and the positioning sliding sleeve 29 drives the positioning slide bar 32 to slide inside the positioning slide groove 33, which can ensure better stability when the transmission rack 20 moves. At the same time, the transmission rack 20 drives the movable seat 21 to move, the movable seat 21 drives the movable shaft 22 to move, the movable shaft 22 drives the movable connecting bar 23 to move, and the movable connecting bar 23 pushes the connecting seat 16 downward through the connecting shaft 24. The connecting seat 16 drives the arc-shaped positioning seat 15 to move downward, and the arc-shaped positioning seat 15 drives the second sliding block 25 to slide inside the second sliding groove 26, which can ensure better stability when the arc-shaped positioning seat 15 moves;

[0035] At the same time, the two ends of the arc-shaped positioning seat 15 slide downward on the outside of the two positioning vertical rods 34 respectively, and the arc-shaped positioning seat 15 drives the movable frame 35 to slide downward on the outside of the positioning vertical rod 34 through the connecting rod 36. The movable frame 35 moves downward to squeeze the return spring 37, causing the return spring 37 to elastically deform. As the arc-shaped positioning seat 15 moves downward, it will contact the top of the pipeline, and then the arc-shaped positioning seat 15 will push the pipeline downward, and the pipeline will push the arc-shaped support seat 7 to move downward. The arc-shaped support seat 7 drives the support rod 8 to slide downward inside the support sleeve 9, and the support rod 8 pushes the support block 12 to move downward. The support block 12 moves downward to squeeze the support spring 11, causing the support spring 11 to elastically deform, and the support spring 11 is deformed. The change generates a rebound force, which acts on the arc-shaped support seat 7 to provide an upward thrust for the positioning of the pipeline, and then cooperates with the downward pressure of the arc-shaped positioning seat 15 to position the pipeline. After the pipeline is positioned, the adjustment block 41 is stopped from rotating, and then the locking nut 45 is tightened to re-position the adjusting shaft 40. When it is necessary to release the positioning of the pipeline, the locking nut 45 is loosened to release the positioning of the adjusting shaft 40. At this time, under the rebound force of the return spring 37, the movable frame 35 is pushed upward, and the movable frame 35 drives the arc-shaped positioning seat 15 to move upward through the connecting rod 36, so that the positioning of the pipeline can be released. In this way, the pipeline support and hanger can quickly position and release the pipeline during use;

[0036] In addition, during the positioning process of the pipeline, the pipeline will expand due to heat under high temperature conditions. The force generated by the expansion will push the arc-shaped support seat 7 downward. The arc-shaped support seat 7 squeezes the support spring 11 through the support rod 8, which can ensure the stability of the pipeline while taking into account displacement compensation. In this way, the pipeline support bracket can achieve the effect of high-temperature adaptive load-bearing during use.
