[0033] The lofting and positioning device 10 in this embodiment includes a cantilever beam 13. One end of the cantilever beam 13 is tightly sleeved on the ring-shaped structural body 11 through a sleeve clamping structure 14, and can move circumferentially along the structural body 11 to another circumferential position of the structural body 11 together with the sleeve clamping structure 14 when the sleeve clamping structure 14 is loosened.

[0034] The other end of the cantilever beam 13 is provided with a lofting positioning structure 15, and the lofting positioning structure 15 includes a rotating body 16, a rotating shaft 17, a pressing block 18 and a positioning pin 19; the rotating body 16 is placed on the cantilever beam 13, and a receiving groove 20 formed by concave is provided on the upper end surface of the rotating body 16. The rotating shaft 17 vertically passes through the rotating body 16 and the cantilever beam 13 from the receiving groove 20. The upper end of the rotating shaft 17 has an axially enlarged shaft head 21, and the shaft head 21 is received in the receiving groove 20. A nut 22 is threadedly connected to the lower end of the rotating shaft 17. The nut 22 can be tightened to press the rotating body 16 against the cantilever beam 13 or loosened to allow the rotating body 16 to rotate around the rotating shaft 17; the pressing block 18 is adjustably connected to the rotating body 16, and a slot hole 23 is defined in the horizontal direction between their corresponding surfaces. The positioning pin 19 is horizontally fitted in the slot hole 23, and can be fixedly pressed between the pressing block 18 and the rotating body 16 when the pressing block 18 and the rotating body 16 are tightened relatively, and the length of its telescopic amount can be adjusted when the pressing block 18 and the rotating body 16 are loosened relatively.

[0035] In this embodiment, a semi-cylindrical groove is provided on the lower surface of the pressing block 18, and a semi-cylindrical groove is provided on the upper surface of the rotating body 16. The two semi-cylindrical grooves enclose the slot hole 23 for receiving the positioning pin 19. The pressing block 18 is threadedly connected to the rotating body 16 through a locking screw 25.

[0036] The cantilever beam 13 in this embodiment is composed of a rectangular pipe-shaped steel.
