Abstract

The invention relates to a movable automatic lifting device for an insulating box for an LNG ship. The automatic lifting device comprises a bottom plate, a control box, a lifting arm, pulleys, a steelwire rope and a lifting hook, wherein one end of the lifting arm is fixedly installed at the upper end of the bottom plate at one side of a cabin; one end of the steel wire rope is connected with a motor, and the other end of the steel wire rope penetrates through the pulleys to be connected with the lifting hook; and a top fixing head is arranged at the other end of the lifting arm; the top fixing head comprises a first top column, a second top column and a top plate; the first top column is fixedly installed at one end of the lifting arm; one end of the second top column is fixedly connected with the center of the top plate, and the other end of the second top column is hinged into one end of the first top column; and the top fixing head can adjust the angle according to the shape of abulkhead. Through the automatic lifting device provided by the invention, the insulating box can be hoisted in the cabin, so that rapid carrying of the insulating box is achieved in the construction process of a liquid cargo tank enclosure system of the LNG ship, the manual carrying amount is effectively reduced, and damage in the manual carrying process is prevented.

Description

technical field [0001] The invention relates to the field of shipbuilding equipment, in particular to an automatic lifting device for a movable insulating box of an LNG ship. Background technique [0002] In the construction process of the liquid cargo tank of the membrane type LNG ship, the construction of the liquid cargo containment system is the main work. Keep the pressure to prevent the liquid natural gas inside from absorbing heat from the cargo tank and keep the liquid natural gas stable. The main work of the liquid cargo containment system is the installation of the insulation box. The insulation box coated with epoxy resin needs to be installed on the hull. In order to realize the construction of the liquid cargo containment system, there is a scaffolding platform in the cabin, which is about 8 floors , before the insulation box is installed, the corresponding insulation box needs to be moved to the corresponding scaffold level. [0003] In the prior art, the ele...
