Abstract

The invention discloses a method for hoisting an annular block of a fishery scientific investigation ship into dock. The method comprises the following steps that a plane supporting steel pier and a slope supporting steel pier are arranged, a guide sliding groove is formed in the side, deviating from a ship body, of the plane supporting steel pier, and a steel pier guide wheel is arranged on the side, deviating from the ship body, of the slope supporting steel pier; the plane supporting steel pier and the slope supporting steel pier are connected through a supporting tubular column, two gantrycranes are selected for joint hoisting, hooks of the gantry cranes are connected with self-balancing hanging rows respectively, four lower fixed pulleys are arranged at the lower ends of the self-balancing hanging rows and connected in series through lower transition steel wire ropes, and three annular hanging points are formed on each lower transition steel wire rope; upper middle transition pulleys are arranged in the annular hanging points and connected with lower middle transition pulleys respectively; an annular hanging belt sequentially penetrates through the steel pier guide wheel andthe guide sliding groove; and the gantry cranes hoist the annular block in place. The carrying efficiency can be improved, and the influence caused by the dead weight of the tool when the block is hoisted through a traditional process is reduced.

Description

technical field [0001] The invention belongs to the technical field of ship building, and in particular relates to a method for hoisting and docking an annular general section of a fishery scientific research ship. Background technique [0002] Carrying in the ship building process refers to the process of combining the hull into a whole ship by sections or general sections. The fishery scientific research ship is different from the conventional ship type. The ship has the characteristics of thin board, weak structure and complex and dense equipment. When docking, it is necessary to fully consider its structural deformation and protection measures for embedded equipment. Therefore traditional hoisting method is to adopt rigid bracket as platform, put supporting steel pier and wedge-shaped pier wooden hull annular general section its top general assembly on the bracket. There are hoisting rings on both sides of the bracket, and the total section is hoisted by connecting the ...
