Detailed Description

The technical scheme of the hoisting operation platform of the wind driven generator precast concrete tower tube shell section of the present invention is further described in detail with reference to the drawings and the specific embodiments.

As shown in fig. 1 to 6, in the embodiment, the modularly assembled multi-stage work platform includes:

the first-stage central platform 1 can be hoisted in a C-section shell ring with the smallest shell diameter in the multistage reducing precast concrete tower barrel and comprises a central platform main body in a C-shaped structure;

the second-stage segmented platform 2 is assembled with the first-stage central platform and then can be hung in a B-stage shell ring with the diameter larger than that of the C-stage shell ring in the multistage reducing precast concrete tower cylinder, and comprises a plurality of second-stage platform units, and the plurality of second-stage platform units are assembled with each other and then are surrounded outside the central platform main body in a C-shaped structure;

and the three-stage segmented platform 3 can be hung in the section A shell ring with the largest shell diameter in the multistage reducing precast concrete tower cylinder after being assembled with the two-stage segmented platform, and comprises a plurality of three-stage platform units, and the inner side of each three-stage platform unit is connected to the outer part of the two-stage segmented platform in a surrounding mode through an assembling piece.

As the utility model discloses a technical scheme's a preferred embodiment, be equipped with the frame construction that installation electric block and material were used on the platform of one-level center, in this embodiment, frame construction is the steel frame who sets up in platform center department of one-level center.
