Variable stiffness laying and recycling device carried on ship

Abstract

The invention discloses a variable stiffness laying and recycling device carried on a ship. The tail of a fixed frame is connected with a lifting arm of a crane through a bolt, a pulley tight pressingdevice comprises four small pulleys capable of sliding in the radial direction, spring damping provides pressing force, a high-pressure air pipe passing through is subjected to air leakage, an air pipe without passing through is subjected to pressure maintaining, a first fixing position is provided, the tail end (close to a lifting hook) of the high-pressure air pipe communicates with an air inlet and outlet device, constant air pressure of the high-pressure air pipe is achieved, certain rigidity of the high-pressure air pipe wrapping a mooring rope is kept, meanwhile, a pulley and track combined device is matched with a spring damping device, a pulley and a track generate a second fixing position below the pulley tight pressing device, and the swing angle of the whole mooring rope is reduced.

Description

technical field [0001] The invention relates to the technical field of deploying and recovering marine hull cranes, in particular to a deploying and recovering device with variable stiffness mounted on a hull. Background technique [0002] With the continuous development of modern science and technology, the exploration of the ocean continues to deepen, and the exploration equipment is constantly updated. Among them, unmanned boats are particularly outstanding as ocean exploration tools. However, there are still many problems in the process of deploying and recovering heavy objects such as unmanned boats at sea. Under the influence of the impact, it is easy to collide with the side of the mother ship and cause damage to the unmanned boat. It’s not just that heavy objects shake when working at sea. Even on flat land, when the crane is hoisting or lowering heavy objects, it is inevitable that the heavy objects will sway in the air due to the influence of wind. Contents of ...

However, there are still many problems in the deployment and recovery of heavy objects such as unmanned boats at sea. Under the influence of the ship, it is easy to collide with the side of the mother ship and cause damage to the unmanned boat

It’s not just that heavy objects shake when working at sea, even on flat land, when the crane is hoisting or lowering heavy objects, it is unavoidable to be affected by the wind, causing the heavy objects to sway in the air
