Stabilizing structure of floater salvaging device

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.
