Description

Technical Field

[0001] The utility model belongs to the technical field of shipbuilding, and more specifically relates to a special-shaped steel hoisting device for shipbuilding. Background Art

[0002] The marine bulb flat steel is the most important type of marine special-shaped steel. It is composed of a spherical ball head and a flat web, and is an asymmetric steel. It is mainly used for ship structural reinforcement. According to the requirements of the hull structure strength design, many areas of the entire ship hull are reinforced in the form of bulb flat steel. Bulb flat steel, one of the marine steel sections, has an irregular ball head due to its special shape structure. There are difficulties in matching the clamping chuck of the hoist during the lifting process. Combined with the current status of existing hoists and lifting methods, a multifunctional bulb flat steel clamping hoist is studied and designed. The hoist structure is explained, the action principle is introduced, and the strength of the hoist is checked. The hoist will realize the rapid lifting of bulb flat steel and can meet various installation direction requirements of bulb flat steel, accurately and efficiently, and reduce manpower. The lifting of bulb flat steel, so far, the existing technology still mainly adopts the traditional lifting method, using an upright steel plate clamp to clamp the lower end of the bulb flat steel, with the ball head of the bulb flat steel facing down, and lifting it to the installation position. Because it cannot be positioned directly on the steel plate, a simple tooling is required for manual turning and positioning. The structure of the simple tooling is mainly a round tube with a round plate installed at one end. The round plate has an open groove for clamping the ball head of the flat steel. When in use, the open groove clamps the ball head of the flat steel, and pressure is applied to the round tube to flip the flat steel and stand it up for positioning. When using such a structure, time and manpower are wasted, the labor intensity is high, and the tooling efficiency is not high.

[0003] There is a technology named "hoisting mechanism and ship" and publication number "CN117326447A" in the prior art, which belongs to the field of vehicle hoisting technology and discloses a hoisting mechanism and a ship. The hoisting mechanism includes a mounting seat, an outer hook, an inner hook and a driving assembly. The mounting seat is used to be fixedly connected to the deck; the outer hook is rotatably connected to the mounting seat, and the outer hook is used to lift heavy objects; the inner hook is rotatably connected to the mounting seat, and the outer hook has an opening, and the inner hook can move relative to the outer hook to open or close the opening; the driving assembly is used to drive the outer hook to rotate relative to the mounting seat, and at the same time drive the inner hook to rotate relative to the mounting seat, and the rotation direction of the outer hook is opposite to the rotation direction of the inner hook, so that the driving assembly can simultaneously drive the outer hook and the inner hook to rotate in opposite directions relative to the mounting seat, so that the inner hook can cooperate with the outer hook to open or close the opening, and when the opening is opened, heavy objects can be loaded and unloaded; when the opening is closed, the heavy objects can be prevented from falling off, and the disassembly and assembly operations are simple.
