Description

Technical Field

[0001] This utility model relates to the technical field of suspended platform lifting devices, and in particular to a suspended platform lifting device for water operations. Background Technology

[0002] A floating platform lifting device is a specialized device used in aquatic environments to achieve the vertical lifting and lowering of a platform. It is a key component of floating platform systems, designed to minimize environmental damage, prevent loss of valuable cargo, and ensure maritime safety. Utilizing specialized equipment, it assesses, stabilizes, and recovers assets. With the increase in global shipping activity and the number of vessels on key routes, the demand for marine salvage services is also growing. Environmental concerns and regulations have driven the timely and safe removal of sunken or grounded vessels, promoting market development and technological advancements, particularly in diving technology and marine support vessels, which have improved the efficiency of marine salvage operations.

[0003] A search revealed Chinese patent publication number CN209942206U, which discloses a construction suspended platform lifting device. The device includes a frame body, with a limiting seat fixedly connected to one end. A base is fixedly connected to the end of the frame body away from the limiting seat. A counterweight is fixedly connected to the top of the base, and a winch is fixedly connected to the top of the counterweight. A steel wire rope is fixedly connected to the outer wall of the winch, and a waterproof cover is provided on the outer wall of the winch. The waterproof cover covers the winch, and a limiting pulley is fixedly connected to the outer wall of the waterproof cover. When workers are performing high-altitude operations, the steel wire rope is passed through a collection... The collection trough is secured by clamps on the wire rope. In the event of falling objects from a height, the collection trough can block the falling objects, preventing them from injuring workers. It can also collect the falling objects, preventing them from falling back down and injuring workers on the ground. However, due to the swaying of the water surface and the influence of water flow, it is difficult for the suspended platform lifting device to accurately position the platform to the target location. Its positioning accuracy is much lower, making it impossible to accurately stop the platform at the location requiring maintenance. Repeated adjustments are needed, increasing the operation time and difficulty. It has a weak ability to cope with complex working conditions, making the operation of the suspended platform lifting device even more difficult. Utility Model Content
