Problems solved by technology

However, these hoisting methods are all for tower installation from top to bottom. During the construction process, the cost of hoisting machinery and the difficulty of hoisting will increase with the increase of blade height. At the same time, it will be limited by the installation area, and the cost of renting hoisting equipment is expensive.

Embodiment 1

[0048] As shown in the figure, a device for installing a wind power generator and a tower includes a tower foundation 1, a guide rail installation platform foundation 9, a load-bearing support frame foundation 2, a cable anchor foundation 20, and an installation stabilization device 16. The load-bearing support The frame foundation 2 is arranged around the tower foundation 1, and the cable anchor foundation 20 is arranged on the periphery of the load-bearing support frame foundation 2;

[0049] The load-bearing support frame base 2 is provided with a load-bearing support frame 4, the top of the load-bearing support frame 4 is provided with a reinforced connecting beam 3, and the end of the reinforced connecting beam 3 close to the tower foundation 1 is fixedly provided with an anti-tilt. The guiding device 5, the top of the reinforcement connecting beam 3 is provided with a jacking jack 11, the lifting jack is longitudinally provided with a steel strand 8, and the side of the l...

Embodiment 2

[0064] The difference between this embodiment and Embodiment 1 is: the tower 12 is divided into two ends as a whole for jacking and installation, including the following steps:

[0065] 1) The tower as a whole is divided into standard tower sections with a height of 5 meters; when each standard section of the tower is jacked up from the sliding platform 10, the standard section of the tower is lifted to the bottom and is 10 5.1 away from the sliding platform height in meters;

[0066] 2) When the top surface of the standard section of the topmost section tower is lifted to a height of about 5 meters above the load-bearing platform, the lifting and installation of the first section of the tower 12 are completed, and the installation of the fan engine room 14 is carried out; the fan After the installation of the engine room 14 is completed, the jacking and installation of the standard section of the tower continues until the height of the tower 12 reaches the standard.

Embodiment 3

[0068] The difference between this embodiment and Embodiment 2 is that the blades 30 of the fan are installed piece by piece through the chopping rod crane 15, including the following steps:

[0069] 1) After the installation of the fan cabin 14 is completed, two blades 30 are installed above the fan cabin 14; the directions of the two blades 30 are inclined upward;

[0070] 2) When the height of the tower 12 rises to a height just enough to install the third blade 30, install the third blade below the fan nacelle 14, and the direction of the blade 30 is vertically downward.

Abstract

The invention discloses a device for installing a wind power generation fan and a tower drum. The device comprises a load-bearing supporting frame, a reinforcing connecting cross beam is arranged at the top of the load-bearing supporting frame, and a jacking jack is arranged at the top of the load-bearing supporting frame; a sliding platform guide rail is arranged on the tower drum foundation, and a sliding platform is installed on the sliding platform guide rail. The construction method comprises the following steps: 1) foundation construction; 2) mounting and constructing a bearing support frame; (3) installing and constructing a cable anchor, a jacking jack and the like; (4) mounting a tower drum; (5) the carriage beam and the tower drum are jacked; and (6) a fan cabin and blades are installed. The method has the advantages that the problems that in a traditional construction and arrangement method, a tower drum is installed from top to bottom, and the hoisting machine cost and the hoisting difficulty are increased along with the increase of the blade height are solved; the hoisting cost and the labor cost of the tower drum in a traditional construction and arrangement method are saved; the method replaces a traditional construction and arrangement method, and breakthrough in the length of the installed wind turbine generator blades can be achieved.

Description

technical field [0001] The invention relates to the technical field of installation and construction of wind energy generating fans, in particular to a device for installing wind energy generating fans and towers and a construction method thereof. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. Wind turbines are generally composed of wind turbines, generators (including devices), regulators (tails), towers, speed-limiting safety mechanisms, and energy storage devices. [0003] At present, the construction and installation of wind turbines are mainly carried out by the following methods: the direct hoisting and splicing installation method of the crane: the fan and the tower are divided into several parts, and then the large crane is directly used for on-site hoisting and assembly in sequence. Matryoshka type hydraulic synchronous lifting ...
