10. A method for hanging a wind tunnel body component is characterized by comprising the following steps: the method comprises the following steps:
s1, mounting the connecting platform (201), the adjustable suspension pull rod (101) and the wind tunnel body component on a reference platform into a whole, temporarily placing the connecting platform on an auxiliary mounting bracket, adjusting the central line of the connecting platform (201) to be parallel to the central line of the wind tunnel body component, and ensuring that the distances from the upper surfaces of the two pairs of connecting platforms (201) to the central line are equal;
s2, marking on the upper surface of the connecting platform (201), wherein a line is parallel to the central line of the wind tunnel body component, and a line is vertical to the central line of the wind tunnel body component, and the end part of the adjustable suspension pull rod (101) is connected to the sliding seat (103) of the portal frame (104);
s3, solidifying the horizontal plane passing through the center line of the wind tunnel body into a laboratory workshop, adjusting the laser theodolite reference to the horizontal and vertical symmetrical reference planes of the wind tunnel body, and recording the reading;
and S4, placing height gauges on the connecting platform (201) by taking scribed lines as references, respectively measuring the positions and readings of the height gauges placed on the two suspension hoop platforms by using a laser theodolite to perform position calibration, and adjusting the lengths of the coarse thread pull rod (302) and the fine thread pull rod (304) of the adjustable suspension pull rod system to realize the position adjustment of the wind tunnel body component.
