Method and special tool for high-altitude dismantling of ship outer plate lifting ring

Abstract

The invention relates to a method for high-altitude dismantling of a ship outer plate lifting ring, the method comprises the following steps: connecting and fixing the ship planking lifting ring to be cut off by using a first iron chain, lifting the first iron chain through a rocker arm to drive the lifting ring to rise to a deck after the lifting ring is cut off, and then pushing a trolley to move backwards to loosen a second iron chain on the rocker arm, slowly lifting the rear end of the rocker arm to enable the front end of the rocker arm to incline downwards, placing the hanging ring on the deck surface, and completing high-altitude dismounting work of the hanging ring; the invention further relates to a special tool for high-altitude dismantling of ship outer plate lifting ring. The to-be-cut hanging ring is fixedly connected through the first iron chain, the hanging ring is lifted to the deck to be placed through the first iron chain after being cut off, the risk of high-altitude falling after the hanging ring at the outer plate is detached is avoided, operation safety is improved, meanwhile, the dock is prevented from being damaged, the tool is easy to operate, multi-person operation is reduced, and the recovery difficulty is reduced.

Description

technical field [0001] The invention relates to ship building, in particular to a method and special tooling for high-altitude dismantling of ship outer plate suspension rings. Background technique [0002] At present, in the process of ship construction, it is inevitable that the frame surface cannot be installed with lifting rings, so the lifting rings are installed on the outer plate of the segment. However, after installing the lifting rings in this case, it is necessary to turn the segments into Carry out normal loading. After the segmental loading is completed, the lifting ring is at a higher position, and there are also corbels in the segmental outer plate with a large linearity. The lifting rings and corbels must be removed after the loading is completed. [0003] The lifting rings and corbels cannot be fixed during the dismantling process, and the weight of a single lifting ring and corbel is relatively heavy. The existing technology uses direct cutting and letting ...

[0002] At present, in the process of ship construction, it is inevitable that the frame surface cannot be installed with lifting rings, so the lifting rings are installed on the outer plate of the segment. However, after installing the lifting rings in this case, it is necessary to turn the segments into Carry out normal loading. After the segmental loading is completed, the lifting ring is at a higher position, and there are also corbels in the segmental outer plate with a large linearity. The lifting rings and corbels must be removed after the loading is completed.

[0003] The lifting rings and corbels cannot be fixed during the dismantling process, and the weight of a single lifting ring and corbel is relatively heavy. The existing technology uses direct cutting and letting them fall freely to the dock. This method cannot safely place them in a fixed position after dismantling. Recycling It is very difficult, and the falling rings will cause damage to the dock. When cutting off the rings, multiple people are required to work, and the economic benefit is low
