Step 1: first the superconducting magnet of NMR protected will be needed to be mounted on protective frame (6) inside, during installation wheel seat (19) Internal pulley (21) faces the annular groove that superconducting magnet of NMR both ends open up, and drives followed by external PLC controller It moves all air pumps (15) to start, first drives the second Pneumatic extension bar (27) to extend using air pump (15), it is pneumatic using second The elongation of telescopic rod (27) come drive locating rack (16) adjust position, press from both sides superconducting magnet of NMR by six locating racks (16) Gu it is internal in protective frame (6), superconducting magnet of NMR is disposed and is protected using protective frame (6)；

Step 2: when the superconducting magnet of NMR after installation needs according to the actual situation and actual demand adjusts the angle, lead to Crossing air pump (15) drives the first Pneumatic extension bar (18), the second Pneumatic extension bar (27) flexible, first controls the first Pneumatic extension bar (18) annular groove for extending to drive wheel seat (19) from the internal both ends for ejecting and accessing superconducting magnet of NMR of accommodating groove (17) Inside, then control the position that the second Pneumatic extension bar (27) shrinks that locating rack (16) is driven no longer to fix superconducting magnet of NMR It sets, entire superconducting magnet of NMR rotates inside protective frame (6) by the rotation of six pulleys (21) at this time, works as adjustment After complete angle, air pump (15) are controlled to drive two second Pneumatic extension bars (27) to reset, PLC controller is recycled to control air pump (15) come drive the first Pneumatic extension bar (18) reset, superconducting magnet of NMR can be retightened；

Step 3: superconducting magnet of NMR first passes through PLC controller control hydraulic pump when needing significantly to adjust the angle (3) start, drive two hydraulically extensible mandrils (11) to shrink using hydraulic pump (3), be pressed against hydraulically extensible mandril (11) no longer Protective frame (6) drives transmission shaft using driving motor (23) at this time again by PLC controller control driving motor (23) starting (22) it rotates, so that driving wheel (8) be driven to rotate, driving wheel (8) drives four transmission wheels (4) to rotate using conveyer chain (10), To drive protective frame (6) to rotate together, auxiliary wheel (7) assists its rotation to protective frame (6) in the course of rotation, to complete Significantly adjustment to superconducting magnet of NMR angle drives hydraulically extensible mandril using hydraulic pump (3) after completing adjustment (11) it resets, so that protective frame (6) position is fixed.
