Embodiment Construction

[0065] The present invention is mainly a method adopted for the installation of a 3MW wind power generating set. The present invention will be further described below in conjunction with accompanying drawing.

[0066] The main parameters of the 3MW fan equipment are as follows:

[0067]

[0068] The main steps and installation requirements of the 3MW wind turbine installation method of the present invention are as follows:

[0069] 1. Main crane selection

[0070] From the above table, it can be seen that the tonnage and volume of the 3MW fan unit equipment are much larger than that of the 2.5MW and below fan unit equipment. The weight of the cabin has reached 120t, and the size parameters (length, width, height) Reached 12.3m x 5m x 6.5m. When the main crane is hoisting the unit equipment, not only the load of the main crane must be considered, but also whether the hoisted unit equipment will collide with the boom of the main crane during construction to avoid dangerous...

Abstract

The invention discloses a method for installation of a 3 MW wind generating set. The method includes the steps that a main crane is selected; a tower is installed; a cabin is installed; an impeller is installed; vane bolts are tightened through torque; the tower, the cabin and impeller bolts are fastened through torque; and cables are laid and installed. Main crane selection includes the steps that a 630 t crawler belt crane is adopted as the main crane, a working condition of tower type superlift with a 72m main arm and a 36m auxiliary arm is adopted, the auxiliary arm is hinged to the top end of the main arm, and an arm rod of the main crane is formed in a combined mode; and when the cabin is lifted, the main arm, the auxiliary arm and the cabin ascend in a trapezoid shape, and therefore the smallest distance between the cabin and the arm rod is larger than or equal to 5m. By means of the method, the cabin can be prevented from colliding with the arm rod, the impeller and the cabin are in stable butt joint, and the vane bolts are tightened. Construction safety is better guaranteed, the construction progress is accelerated, and construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of wind power generating set installation. Background technique [0002] In recent years, with the promotion of green and clean energy, the wind power industry has sprung up and developed rapidly. At the same time, with the rapid development of wind turbine research and manufacturing technology and the continuous improvement of unit performance, the single unit capacity of land-based units has grown from 750kW wind turbines to relatively mature 3MW wind turbines, and the tonnage and volume of unit equipment have changed accordingly. Larger, which requires higher construction technology and quality for the installation of unit equipment. Such as figure 1 As shown, when the existing 650-ton crawler crane (full main arm working condition) lifts the nacelle to the highest position, the safe distance between the nacelle and the boom is only 0.5m. During the installation of 3MW wind turbine equipment, it is nec...
