Document Type and Number:
WIPO Patent Application WO/2023/082748
Kind Code:
A1
Abstract:
An apparatus for vertically lifting and installing a variable-diameter unbalanced-load device, the apparatus comprising: a track (10) and a track-type transport device (20) mounted on the track (10); and further comprising: a lifting frame (30), comprising a plurality of support columns (31) and, connected at the upper portions of the support columns, a mounting rod (32), wherein the lifting frame (30) is disposed transversely above the track (10); and further comprising: a plurality of groups of lifting centralized-control apparatuses (40) mounted at different orientations on the outer side of the lifting frame (30), wherein the lifting centralized-control apparatuses (40) are used, after the track-type transport device (20) transports a variable-diameter unbalanced-load device into the lifting frame (30), for stably lifting the variable-diameter unbalanced-load device to a mounting position. Additionally disclosed is a method for vertically lifting and installing a variable-diameter unbalanced-load device. The apparatus and the method are highly versatile, reduce installation difficulty, are successful at reducing risks such as severe weather, have a high safety coefficient, can adapt to the requirements of complex lifting working conditions such as variable-diameter tower sections and unbalanced loads, occupy a small amount of space, involve little auxiliary installation work, and are relatively economical in installation.
