Wind turbine base flip installation device

Abstract

The invention discloses a device for overturning and installing a base of a wind driven generator and belongs to the field of wind driven generator manufacturing assisting equipment. An L-shaped overturning frame is hinged to the middle of a main support and comprises a first underbed and a second underbed which are connected into an L shape, a first lifting table and a second lifting table are connected to the first underbed and the second underbed through lifting mechanisms respectively, and an oil cylinder push plate is arranged on the outer side of the position where the first underbed is connected with the second underbed; an oil cylinder is hinged to the inner side of the rear end, corresponding to the first underbed, of the main support, the stretching-out end of a piston rod of the oil cylinder is hinged to the oil cylinder push plate, movable working tables are arranged on at least one side of the front end, corresponding to the second underbed, of the main support, and the movable working tables can rotate and can also move to the upper side of the second underbed. When the device works, the overturning frame overturns the whole base by 90 degrees and then moves the base to the movable working tables for installation. When the device is used for overturning and moving the base of the large wind driven generator, impact is avoided, the base can not be damaged, and working efficiency and safety performance are improved remarkably.

Description

technical field [0001] The invention relates to a manufacturing auxiliary equipment of a wind power generator, in particular to a base installation auxiliary device of a large wind power generator. Background technique [0002] In the prior art, there are many technical difficulties in the assembly of large-scale wind generators with a single capacity of 1.5MW or more, one of which is the installation of the base of the generator. The base of this large-scale wind generator has two mounting surfaces. One is the installation surface connected to the main engine of the generator, and the other is the installation surface connected to the top of the tower. The angle between the two installation surfaces varies with different installed capacities, and is roughly 83°~87° °, during factory production, components such as yaw bearings, brake discs and brakes need to be installed on the installation surface in advance. More than two truss trucks lift the base, and then switch the li...

Problems solved by technology

Its disadvantages are: due to the irregular shape of the generator base itself, it is not only heavy, but also the center of gravity is on one side. The impact of the truss car is large, it is difficult to control, and it is easy to cause accidents. In addition, this method of turning over the generator base has low production efficiency. During the turning process, it is easy to damage the installation parts and the base itself.
