Ship hoisting device

Abstract

The invention discloses a ship hoisting device. The ship hoisting device comprises a device base and a cross beam, wherein a steel column is fixedly arranged on the upper surface close to the cross beam of the device base; a bottom plate is arranged on the top of the outer wall of one side of the steel column; angle steel is fixedly arranged at a position far away from the bottom plate between thesteel column and the cross beam; the lower surface close to the angle steel of the cross beam is provided with a first fixed pulley; the upper surface of the device base is provided with a copper core motor and a limiting frame; a rotation rod is movably arranged at one end passing through the limiting frame of the copper core motor; the outer surface of the rotation rod is sleeved with a coilingsleeve; the upper surface of the bottom plate is provided with a positive-negative rotation motor; a threaded rod is arranged at a position at which the cross beam passes through one side wall. The hoisting device is more convenient for pulling out and withdrawing a traction line, and the moving range of the coiling sleeve is fixed. Meanwhile, ship hoisting operation under different distances canbe realized. The ship hoisting device is novel in structure, and has very high practicability.

Description

technical field [0001] The invention relates to the technical field of ship engineering, in particular to a ship hoisting device. Background technique [0002] After the hull structure is pre-assembled to form sections or general sections, it needs to be transported to the berth with a hoisting device and then assembled and welded to form the entire hull, that is, the general assembly of the hull, also known as large closing. On the basis of assembly and welding, general section assembly and welding, outfitting and painting, the overall assembly and welding of the ship and the process of outfitting and painting are completed on the berth, which is directly related to ensuring the quality of ship construction and shortening the construction period of ships. , when the traditional hoisting device is in use, when the ship is hoisted with the traction rope, the range of motion of the coil sleeve is not limited, which brings inconvenience to the use of the device. At the same tim...

[0002] After the hull structure is pre-assembled to form sections or general sections, it needs to be transported to the berth with a hoisting device and then assembled and welded to form the entire hull, that is, the general assembly of the hull, also known as large closing. On the basis of assembly and welding, general section assembly and welding, outfitting and painting, the overall assembly and welding of the ship and the process of outfitting and painting are completed on the berth, which is directly related to ensuring the quality of ship construction and shortening the construction period of ships. , when the traditional hoisting device is in use, when the ship is hoisted with the traction rope, the range of motion of the coil sleeve is not limited, which brings inconvenience to the use of the device. At the same time, the position of the hoisting parts of the device is fixed, which cannot meet the requirements Hoisting requirements of ships at different distances
