Hoisting overturning device for concrete tower drum and hoisting overturning method

Abstract

The invention provides a hoisting overturning device for a concrete tower drum and a hoisting overturning method. The hoisting overturning device comprises a hoisting frame body, a pair of tower drum hoisting cables, a first chain block and a second chain block, wherein an upper suspension point connected with a hoisting device is arranged at the upper part of the hoisting frame body; four lower suspension points connected to the concrete tower drum are symmetrically arranged on the lower part of the hoisting frame body; the four lower suspension points include a pair of main suspension points and a pair of secondary suspension points, the main suspension points and the secondary suspension points are symmetrically arranged relative to the upper suspension point; the upper ends of the tower drum hoisting cables are correspondingly connected to the main suspension points, and the lower ends of the tower drum hoisting cables are connected to side lifting lugs in the outer circumferential surface of the concrete tower drum; the side lifting lugs are positioned on the outer circumferential surface of the concrete tower drum along the radial direction of the concrete tower drum; the upper ends of the first chain block and the second chain block are correspondingly arranged on the secondary suspension points, and the lower ends of the first chain block and the second chain block are correspondingly connected to an upper lifting lug at the upper end of the concrete tower drum and the lower lifting lug at the lower end of the concrete tower drum.

Description

technical field [0001] The invention relates to the hoisting of concrete towers, in particular to a hoisting and turning device and a hoisting and turning method for concrete towers. Background technique [0002] At present, with the continuous development of the wind power industry, in order to solve the characteristics of wind power such as low wind speed, high wind shear, large turbulence, and transportation difficulties in the central, eastern and southern regions of China, in view of the prestressed reinforced concrete wind power tower has good stability and resistance Strong corrosion performance, low maintenance cost, saving steel and convenient on-site processing, etc., and with the development trend of wind turbines with large capacity and high towers, prestressed reinforced concrete towers will have a broader prospect. [0003] However, in the actual construction process, since the concrete tower is self-heavy and the tower on the top of the concrete tower adopts a...
