AI Technical Summary

Technical Problem

Existing deep well and underwater salvage equipment suffers from problems such as rigid rods being prone to jamming, resonance fatigue, lack of directional support in purely flexible ropes, easy collapse of ordinary flat steel strips, and poor power supply reliability, resulting in insufficient operational stability and accuracy.

Method used

The system employs a multi-stage flexible coiling belt retrieval system, which combines a multi-stage belt arm with a joint reversing mechanism to achieve flexible coiling and directional rigid extension. It is equipped with paired end effectors and a hook-type clamping mechanism, and relies on attitude adjustment and control components to achieve multi-dimensional precise attitude adjustment and stable locking.

Benefits of technology

It improves the stability and precision of deep well and underwater salvage operations, adapts to the needs of narrow spaces, reduces equipment risks, and increases operational efficiency and success rate.

Abstract

This invention relates to the field of deep well operation and underwater salvage equipment technology, and discloses a multi-stage flexible coiling belt salvage execution system, including a flexible moving component, an end effector, a hook-type clamping mechanism, and a control component. The multi-stage strip-shaped arms of the flexible moving component are connected by a joint reversing mechanism. The end effectors are arranged in pairs and connected to the flexible moving component via an attitude adjustment component. Their multi-stage auxiliary arms are connected in series through a hinge mechanism. The hook-type clamping mechanism is connected to the end of the end effector via a coiling belt mechanism. During operation, they hook together to form a cross-shaped hook assembly, which surrounds the end effector to form a clamping cavity. Each core mechanism is electrically connected to the control component. This system combines flexible coiling and directional rigid extension characteristics, solving the problems of jamming and lack of directional support in traditional equipment. It can achieve multi-dimensional precise attitude adjustment and target alignment, stable clamping and locking, and synchronized and precise actions of each mechanism, greatly improving the stability, adaptability, and efficiency of salvage operations in narrow spaces.
