[0032] Embodiment 3:

[0033] This embodiment provides a method for using a device for duct hoisting:

[0034] When in use, the device is assembled as a whole, and after the angle steel 401 and the channel steel 201 are in a horizontally opened state, the angle steel 401 is firmly connected to the flange bolt hole corresponding to the air duct to be hoisted through the bolt groove 402. After the device is firmly connected to the air duct, the hoisting structure (such as a fall chain, a small electric hoist, etc.) set at the highest point of the shaft is firmly fixed to the hoisting ring 101 by a hoisting belt (such as a chain, a wire rope, etc. of the hoisting structure), and then the hoisting structure is started. After the air duct to be installed is lowered to the installation position inside the shaft, the air duct is installed and fixed firmly. Then the hoisting device is disassembled from the air duct flange, and then the third nut 407 and the second nut 405 are loosened to make the angle steel 401 fold in the horizontal direction, and at the same time, the channel steel 201 is folded vertically through the hinge 102, and then the device is lifted for secondary hoisting, and this is repeated to finally complete the hoisting of the entire shaft air duct.

[0035] When the long side and wide side of the duct flange are smaller than the length or width of the existing device in the fully open state, the four sets of channel steels 201 can be retracted inwardly through the hinges 102 to appropriately reduce the outer diameter of the device, and at the same time, the duct flange fixing assembly 4 that matches the duct specifications is replaced, and the round steel 205 and the locking nut 206 are used to adjust the angle between the channel steel 201 and the rotating component 3 so that the angle steel 401 and the duct flange remain in a horizontal state, thereby being able to hoist the duct with smaller specifications.
