Detailed Description of the Invention

[0024] The following is a detailed description of a specific embodiment of the present invention in conjunction with the drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0025] Embodiment:

[0026] As Figures 1-4As shown in the figure, an integral hoisting structure and construction method for air ducts provided by an embodiment of the present invention include a guide rail 1 fixed below the roof and a hoisting platform 2 located on one side of the guide rail 1. The guide rail 1 is fixed below the roof by a plurality of expansion bolts 6. A sliding bearing platform 4 is provided on the hoisting platform 2. The sliding bearing platform 4 is used to bear the air duct 3 and can reciprocate along the hoisting platform 2. The hoisting platform 2 can be a lifting platform to facilitate adjusting the installation height of the air duct 3 to match the installation height and facilitate installation alignment. The sliding bearing platform 4 can be selected as a sliding trolley, including a bottom plate and casters. The air duct 3 is borne above the bottom plate. Limit protrusions 21 are provided on both sides of the hoisting platform 2. The limit protrusions 21 are limit blocks to prevent the sliding trolley from moving to the edge. The air duct 3 is limited and fixed by a hanger assembly 5. The hanger assembly 5 is slidably connected to the guide rail 1.

[0027] Specifically, the hanger assembly 5 includes suspension rods 51 on both sides, and an upper cross bar 52 and a lower cross bar 53 located between the suspension rods 51 on both sides. The joints of the upper cross bar 52 and the lower cross bar 53 with the suspension rods 51 are fixedly connected by nuts. The air duct 3 is fixed at the center. The upper ends of the suspension rods 51 on both sides are slidably connected to the guide rail 1. The upper ends of the suspension rods 51 have a "T" - shaped part, and the bottom surface of the guide rail 1 matches the "T" - shaped part.
