8. The installation shield apparatus for a nuclear magnetic resonance superconducting magnet according to claim 1, wherein the method of using the installation shield apparatus comprises the following steps:

the method comprises the following steps: firstly, a nuclear magnetic resonance superconducting magnet to be protected is installed in a protection frame (6), when the nuclear magnetic resonance superconducting magnet is installed, a pulley (21) in a wheel seat (19) faces to annular grooves formed in two ends of the nuclear magnetic resonance superconducting magnet, then an external PLC is used for driving all air pumps (15) to be started, the air pumps (15) are used for driving a second pneumatic telescopic rod (27) to extend, the second pneumatic telescopic rod (27) is used for extending to drive a positioning frame (16) to adjust the position, the nuclear magnetic resonance superconducting magnet is clamped and fixed in the protection frame (6) by six positioning frames (16), and the protection frame (6) is used for arranging and protecting the nuclear magnetic resonance superconducting magnet;

step two: when the installed nuclear magnetic resonance superconducting magnet needs to adjust the angle according to actual conditions and actual requirements, the air pump (15) is used for driving the first pneumatic telescopic rod (18) and the second pneumatic telescopic rod (27) to stretch, the first pneumatic telescopic rod (18) is controlled to extend to drive the wheel seat (19) to eject from the inside of the accommodating groove (17) and enter the annular grooves at two ends of the nuclear magnetic resonance superconducting magnet, the second pneumatic telescopic rod (27) is controlled to contract to drive the positioning frame (16) to not fix the position of the nuclear magnetic resonance superconducting magnet any more, at the moment, the whole nuclear magnetic resonance superconducting magnet rotates in the protection frame (6) by the rotation of six pulleys (21), after the angle is adjusted, the air pump (15) is controlled to drive the two second pneumatic telescopic rods (27) to reset, the PLC controller is used for controlling the air pump (15) to drive the first pneumatic telescopic rod (18) to reset, the nuclear magnetic resonance superconducting magnet can be fixed again;

step three: when the angle of the nuclear magnetic resonance superconducting magnet needs to be adjusted greatly, the PLC controller is used for controlling the hydraulic pump (3) to start, the hydraulic pump (3) is used for driving the two hydraulic telescopic ejector rods (11) to contract, so that the hydraulic telescopic ejector rods (11) do not abut against the protective frame (6), the PLC controller is used for controlling the driving motor (23) to start at the moment, the driving motor (23) is used for driving the transmission shaft (22) to rotate, thereby driving the driving wheel (8) to rotate, the driving wheel (8) drives the four conveying wheels (4) to rotate by utilizing the conveying chain (10), thereby driving the protective frame (6) to rotate together, the auxiliary wheel (7) assists the protective frame (6) to rotate in the rotating process, therefore, the angle of the nuclear magnetic resonance superconducting magnet is greatly adjusted, and the hydraulic telescopic ejector rod (11) is driven to reset by the hydraulic pump (3) after the adjustment is finished, so that the position of the protective frame (6) is fixed.
