[0002] Fusion energy has the advantages of unlimited resources, green and low-carbon, safe and reliable, and is considered to be an effective way to solve the energy crisis of mankind. The magnetic confinement tokamak is currently considered to be the most promising nuclear fusion device for the research and application of controlled nuclear fusion energy. Its principle is to use a certain strong magnetic field to confine and compress high-temperature plasma so that it meets the Lawson criterion, thereby realizing nuclear fusion reaction. Superconducting magnets are one of the core components of the tokamak device, and are generally hoisted in a suitable position through a certain supporting structure. However, during the hoisting process, it is difficult to ensure that the magnets can be installed accurately and there may be a certain angle deviation in the horizontal direction, which will cause some unnecessary troubles in the subsequent operation of the nuclear fusion device.

[0003] Based on the above-mentioned reality, there is an urgent need for a method that can detect the magnet lifting status in real time and level the magnet according to the detection data feedback. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a nuclear fusion armored superconducting magnet hoisting and leveling method and its support system, which ensures that the armored superconducting magnet is stably hoisted on the supporting platform, and controls the height of the magnet in all directions in real time to ensure the balance of the hoisted magnet.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A method for hoisting and leveling a nuclear fusion armored superconducting magnet comprises the following steps:

[0007] S1: Use a gantry truck to pre-lift the magnet to the designated location;

[0008] S2: Power on each laser displacement sensor and each electric hydraulic jack to initialize the electric jack control system;

[0009] The first laser displacement sensor, the second laser displacement sensor, the third laser displacement sensor, and the fourth laser displacement sensor are horizontally installed on the sensor mounting plate along the radial direction of the armored superconducting magnet; four electric hydraulic jacks are respectively installed on the top of the supporting frame, distributed in a cross shape, for hoisting the magnet and regulating the height of the magnet in all directions;

[0010] S3: The first laser displacement sensor emits a laser to measure a first height above the loading ground;

[0011] S4: The second laser displacement sensor emits a laser to measure a second height from the loading ground;

[0021] S14: Operate the No. 4 electric jack to make the boom move in the vertical direction to eliminate the height error;

[0023] Further, the first laser displacement sensor and the second displacement sensor are horizontally mounted on the sensor mounting plate symmetrically about the magnet along the radial direction of the magnet, and the third laser displacement sensor and the fourth displacement sensor are horizontally mounted on the sensor mounting plate symmetrically about the magnet along the radial direction of the magnet.

[0024] Furthermore, the steps S3-S6 are performed synchronously to collect the heights of the magnet from the loading ground in each direction, and measure the first height, the second height, the third height, and the fourth height.

[0025] Furthermore, the steps S7-S10 are performed synchronously to determine whether the positions of the magnets in each direction need to be adjusted.

[0026] Further, in S7-S10, in S7-S10, the difference between the first height H1 and the first set height hset1 is: |H1-hset1|, the difference between the second height H2 and the first set height hset1 is: |H2-hset1|, the difference between the third height H3 and the second set height is: |H3-hset2|, and the difference between the fourth height H4 and the second set height is: |H4-hset2|.
