Centralizing device for integral dismantling and hoisting of single-point sleeve and base plate

Abstract

The invention discloses a centralizing device for integral dismantling and hoisting of a single-point sleeve and a base plate, which comprises a centralizing lantern ring, a centralizing sleeve, a hoisting device, a hoisting device and a hoisting device, and the centralizing lantern ring is movably connected to the outer wall of the single-point sleeve in a sleeving manner; one end of the lower lifting rope is connected to the corner end of the centralizing lantern ring, and the other end of the lower lifting rope is connected to the corner end of the base disc; the floating crane lifting hook is arranged right above the single-point sleeve; one end of the upper lifting rope is connected to the corner end of the centralizing lantern ring, and the other end of the upper lifting rope is connected to the floating crane lifting hook. According to the method, the single-point sleeve and the base plate are integrally dismounted and hoisted by utilizing the existing leveling hoisting points of the base plate, so that the single-point sleeve and the base plate are prevented from overturning in the integral dismounting and hoisting process, new design and installation of the hoisting points are avoided, hanging and unbuckling of a sling are easy to realize, and the hoisting efficiency is improved. Therefore, the purposes of reducing the construction difficulty and improving the construction efficiency for the project are achieved.

Description

technical field [0001] The invention relates to the technical field of sleeve hoisting, in particular to a centralizing device used for integral removal and hoisting of a single-point sleeve and a base plate. Background technique [0002] At present, domestic dismantling and hoisting schemes for the sleeve and the base plate all adopt a new design at the top of the sleeve and install a lifting point to dismantle the sleeve and the base plate as a whole. This hoisting scheme has the following technical problems: 1. The existing leveling lifting points on the base plate are not used, but the lifting points are newly designed and installed, and these lifting points cannot be reused, which wastes material and labor costs; 2. The lifting points can only be installed on the top of the sleeve , and the installation location is mostly located in the splash area, it is difficult to guarantee the welding progress and welding quality of the lifting point; It is very difficult to remov...

[0002] At present, domestic dismantling and hoisting schemes for the sleeve and the base plate all adopt a new design at the top of the sleeve and install a lifting point to dismantle the sleeve and the base plate as a whole. This hoisting scheme has the following technical problems: 1. The existing leveling lifting points on the base plate are not used, but the lifting points are newly designed and installed, and these lifting points cannot be reused, which wastes material and labor costs; 2. The lifting points can only be installed on the top of the sleeve , and the installation location is mostly located in the splash area, it is difficult to guarantee the welding progress and welding quality of the lifting point; It is very difficult to remove the buckle of the tool, and it is usually necessary to build a scaffold tens of meters high to complete the removal. Therefore, the construction ship of this hoisting scheme is long, and the construction risk and cost are relatively high.

Although there are leveling and lifting points on the base plate, since the leveling and lifting points of the base plate are located below the overall center of gravity of the sleeve and the base plate, if only the conventional hoisting scheme is followed, it will be affected by wind, waves and currents during the hoisting process. , it is very easy to cause the overall overturning of the sleeve and the base plate
