Ship ultrahigh stand column hoisting tool and hoisting method thereof

Abstract

The invention relates to a ship ultrahigh stand column hoisting tool. The ship ultrahigh stand column hoisting tool is composed of a lower hoisting unit, an upper hoisting unit, a force transmission unit and a pulling unit. The lower hoisting unit is composed of a left lifting lug and a right lifting lug which are welded to the large-diameter section of the lower portion of the ultrahigh vertical column of the ship. The upper hoisting unit is composed of a hoisting frame, a left hoisting lug plate and a right hoisting lug plate, wherein the left hoisting lug plate and the right hoisting lug plate are welded to the hoisting frame. And in a formal hoisting state, the hoisting frame is sleeved on the periphery of the small-diameter section at the upper part of the ship ultrahigh stand column. The force transmission unit is composed of a left force transmission steel wire rope connected between the left lifting lug and the left lifting lug plate and a right force transmission steel wire rope connected between the right lifting lug and the right lifting lug plate. And the lifting hook is assisted by the pulling unit to realize the traction of the upper hoisting unit. In this way, the design concept that high-altitude unhooking operation is converted into low-altitude unhooking operation is ingeniously achieved, and the problem that high-altitude unhooking of the ultrahigh vertical column of the ship is difficult is solved. In addition, the invention further relates to a ship ultrahigh stand column hoisting method.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a tool for hoisting a ship's super-high column and a hoisting method thereof. Background technique [0002] The 3200T self-elevating wind power installation vessel of the European shipowner company undertaken by COSCO SHIPPING is specially designed for the integration of transportation, lifting and installation of offshore wind turbines, connectors and foundations. According to the design requirements, multiple columns need to be installed on the deck of the 3200T self-elevating wind power installation ship, some of which are over 15m in height and over 1m in diameter, and can weigh more than ten tons. [0003] According to the conventional design, the lifting lugs are pre-welded on the top of the column in the prefabrication workshop. When actually performing hoisting operations, use the lifting lugs on the top to perform turning over and hoisting operations on the column....

AI Technical Summary

Problems solved by technology

According to the existing hoisting process, when the column is hoisted and the unhooking operation is performed, since the lifting lug is in the sky, especially for the column on the third, fourth or even higher floors of the cabin module, the lifting point (hook head) The height above the ground even exceeds 30m. At this time, it is extremely difficult to perform the unhook operation. It is necessary to use a climbing vehicle to manually send the unhook to the designated height. The entire execution process is laborious and time-consuming, and it will also increase the lifting risk of the column to a certain extent. and cost
