Hoisting and recovering system and hoisting and recovering method for underwater robot

Abstract

The invention discloses a hoisting and recovering system and a hoisting and recovering method for an underwater robot. The system comprises a shell, a locking cover is installed at the top end of the shell, a fixing ring is installed below the locking cover, and the fixing ring, the shell and the locking cover form an open type recycling device; a buoyancy ball is installed between the shell and the fixing ring, the upper end of the buoyancy ball is connected with a pull rod, and the pull rod penetrates through the locking cover. The lower end of the buoyancy ball is connected with one end of a connecting rod, the connecting rod penetrates by the locking cover to be connected with a locking block, the locking block is installed in the shell through a pin, and a connecting device of the underwater robot is placed in the shell. According to the invention, lifting and recovery of various types and levels of underwater equipment are realized, so that the purposes of high interchangeability and standardization are realized, and the manufacturing and maintenance cost is reduced.

Description

Technical field: [0001] The invention relates to the technical field of robots, in particular to an underwater robot hoisting and recovery system and a hoisting and recovery method. Background technique: [0002] The traditional underwater robot hoisting and recovery has the following operation modes: [0003] (1) The whole process of human participation: during hoisting work, on the platform or the mother ship, the operator connects and locks the hoisting device (or hook) to the underwater equipment, and hoists the underwater equipment to the In the working area, the diving operator enters the water and moves to the vicinity of the underwater equipment to manually unlock and set the equipment and hook; [0004] During the recovery work, the underwater equipment floats near the mother ship or platform, and the diving operator enters the water, moves to the vicinity of the underwater equipment, manually connects and locks the underwater equipment and hooks, and lifts the und...

AI Technical Summary

Problems solved by technology

[0011] When the spring lock hook is used, the lock hook decoupling device relying on the combination of the spring and the slider is unstable in the working process, and the spring decoupling and failure (loss of elasticity, breakage, deformation, etc.) are very easy to occur, which brings difficulties to the hanging recovery process. Hidden danger

[0012] When the buoyancy block hook is used, this solution can only hoist and recover light underwater equipment, because the buoyancy material itself is powder-molded, its own strength, hardness, and rigidity are poor, and it cannot be hoisted for medium-sized or even heavy-duty underwater equipment
