Underwater orthogonal swinging type neutral cable synchronous conveying mechanism

Abstract

The invention provides an underwater orthogonal swinging type neutral cable synchronous conveying mechanism. The mechanism comprises a swinging frame; the swinging frame consists of two support plates; a big driving wheel is arranged in the swinging frame; the mechanism further comprises a guide cable channel arranged at a cable inlet and a cable outlet on the swinging frame; the cable outlet and the position just facing the cable outlet on the swinging frame are fixedly connected with an external support through a bearing seat and a bearing to form a swinging frame rotary shaft; a cable laying mechanism is arranged on the swinging frame through a through slot on the swinging frame; an intermediate shaft is arranged at the right side of the swinging frame; a small driving wheel support swinging arm is detachably sleeved on the intermediate shaft; the small driving wheel is arranged in the internal side of the other end of the small driving wheel support swinging arm; the big and small driving wheels are driven by one hydraulic motor, and are rotated oppositely through a reversing device on the swing frame; and neutral cable pressure adjusting mechanisms are arranged between the two support plates of the swinging frame and the small driving wheel support swinging arm. The mechanism provided by the invention effectively ensures the power and synchronization of the neutral cable conveying; the neutral cable can be arranged and taken up orderly on a winding drum, thus, the accuracy and reliability for conveying the neutral cable are improved.

Description

technical field [0001] The invention relates to the technical field of underwater operation devices, in particular to underwater operation devices applied to underwater moving bodies such as deep-sea remote control robots, single-person atmospheric pressure diving equipment, deep-sea space stations, and submarines, especially to underwater operation devices applied to single-person atmospheric pressure diving The neutral cable in the system relay station is retracted and released synchronously with the conveying mechanism. Background technique [0002] The single-person atmospheric diving system is mainly composed of three parts: the single-person atmospheric diving suit (ADS), the relay station (TMS) and the surface deployment recovery system (LARS). Among them, the single-person atmospheric pressure diving suit is a humanoid underwater operation system, which can enter some specific areas and can complete some complicated underwater operations that only divers can complete...

Problems solved by technology

[0008] 1. The synchronous conveying mechanism is driven by a single driving wheel, and the surrounding small rollers (or pressure wheels) are passive wheels. Due to the initial release friction of the neutral cable and the positive pressure and friction coefficient of the pressure wheel, and the neutral cable It is related to the wrap angle on the driving wheel, and the positive pressure of the pressure wheel is limited by the optical fiber cable inside the neutral cable, so the conveying force is limited, and it is easy to cause the neutral cable to slip during the conveying process, resulting in the final failure due to insufficient conveying force. Unable to transport neutral cable;

[0009] 2. The steering wheel of the neutral cable in the conveying mechanism is required to swing back and forth along the axis of the reel due to the need for cable discharge, so that during the cable discharge process, there will be a working state where the neutral cable is not perpendicular to the axis of the reel , especially at the two ends of the reel, it will cause the arrangement of the neutral cables to be large or small, irregular, and even jump cables, trap cables, and disordered cables;

[0010] 3. Since the minimum radius of the steering wheel of the neutral cable in the conveying mechanism is greater than or equal to the minimum dynamic bending radius of the neutral cable, the size of the steering wheel is relatively large, and due to the need for cable arrangement, the steering wheel has to swing in space, resulting in synchronization The volume of the conveying mechanism increases, thus occupying a larger space on the relay station, which affects the overall layout of the relay station, especially the larger size of the relay station in the height direction
