Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] 1. The method of salvaging submarine boats with energy storage lifting method:

[0035] In this method, a sufficient number of hoisting points are cut, welded or lashed on the sunken ship or submarine, and two winches that are not at the same place are set on the salvage operation ship on the water surface, and the two hoists retract a steel rope and lift it. The point connection is characterized in that in the lifting point of the sunken boat, pulleys are set at two adjacent lifting points, and the steel rope is pulled up and down by the hoist over the two pulleys. When each steel rope moves downward, load 2 The floating box is twice the initial lifting force of the winch, and the steel handle reciprocates once and adds once. When the weight of a floating box attached to a steel fence reaches the specified weight, hang the lock on a floating box attached to ...

Abstract

An energy-accumulating hoisting method for raising sunken ship or hoisting over-weight and over-long object is disclosed. Two hoisters are arranged on a salvage ship. Many lifting points are arranged on the sunken ship. The steel cable of hoister serially passes through the single pulleys of 2 lifting points. When each steel cable runs up and down in round trip mode, multiple float boxes are tied in accumulative mode until all the lifting point has the float boxes. Another method is uses of float boxes and sunk balls. When all lifting points have been tied with float boxes and sunk balls, the sunk balls is removed and the sunken shift is raised by the float boxes.

Description

technical field [0001] The invention relates to a salvage method for a sunken ship, in particular to a method for hoisting super-heavy and super-long objects on a seabed sunken ship by the energy storage lifting method. Background technique [0002] At present, the salvage technology of the sunken ship that is publicly used is that divers dive into the seabed to find the position of the sunken ship, and then make a mark, and then the divers work underwater to dig out the sediment under the sunken ship, and then tie several steel cables under the sunken ship , tie iron air drums at both ends of each steel cable. There is water in the air drums. After the air drums are tied, they will be inflated and drained. The method is that divers have to work underwater for a long time, which is not only hard work, but also dangerous. The divers dig out the sand bit by bit underwater and dig out several through holes through the bottom of the hull. Due to the action of wind and waves, it...
