Stabilizing structure of floater salvaging device

Abstract

Disclosed is a stabilizing structure of a floater salvaging device. A long hoist arm transversely extending outside of a ship body is arranged on one side of a salvage ship, a support plate is fixed at the extended end of the hoist arm, a clamp support is suspended on the front side and the rear side of the support plate in hinge connection via two oblique hinge rods, an oblique hydraulic oil cylinder is hinged on the left side and / or the right side of the clamp support, the upper end of the hydraulic oil cylinder is hinged to the support plate, and the salvage ship is provided with an angle sensor which controls stretching of a piston rod in the hydraulic cylinder via a control circuit. Since floaters are salvaged on one salvage ship side, the stabilizing structure of the floater salvaging device is applicable to salvage work in high sea conditions. Swaying of a grab is controlled by the oil cylinder, a swaying angle between the clamp support and the salvage ship is tracked in real time, so that swaying of the floater salvaging device can be prevented dynamically.

Description

technical field [0001] The invention relates to the field of salvage at sea, in particular to an anti-shake structure of a floating object salvage device. Background technique [0002] At present, for salvaging floating objects in the sea, salvage ships can usually only salvage close-range salvage, or salvage by auxiliary work ships under low sea conditions with good sea surface climate conditions. However, under high sea conditions with strong winds and waves, and severe weather conditions on the sea surface that may be accompanied by thunderstorms, if the salvage personnel or working boats leave the mother ship and go to sea, the salvage work will become quite dangerous, and it may even be impossible to salvage. Operation. At this time, for some objects that need to be salvaged on board in time, such as rescuing people who fell into the water, salvaging objects that affect the marine environment or objects that are of great value to the owner, the best salvage time will b...

AI Technical Summary

Problems solved by technology

[0008] 1. Since the swing of the four-claw positioning structure is controlled manually by controlling the windlass to retract and release the steel rope, the anti-sway mechanism can only be carried out under the condition that the swing is not too intense. Personnel and fixed floating objects in the four-claw positioning structure bring potential safety hazards;

[0009] 2. When the gantry swings inward and outward, the four-claw positioning structure is prevented from swinging by retracting and releasing the steel rope. The swing is more intense and the swing frequency is higher, the anti-sway effect of this structure is not ideal;

[0010] 3. The side salvage and stern hoisting methods are adopted, and the connection structure between the four-claw positioning structure and the mast is used to limit the lateral swing of the floating object. However, in actual operation, the salvage ship will swing violently under severe sea conditions. , so the force of the connection structure will be relatively bad, and there will be certain safety hazards
