Brake sticking mechanism for detachable saddle of deep sea carrying platform

Abstract

The invention relates to a brake sticking mechanism for a detachable saddle of a deep sea carrying platform. The brake sticking mechanism comprises the saddle, and a pressure-resistant shell is arranged at the bottom of the saddle. Plate belts are symmetrically arranged on the two sides of the outer circumferential face of the pressure-resistant shell, and the tops of the two plate belts are hinged to the saddle. The bottoms of the two plate belts are connected through an elastic connecting assembly. A check block is further arranged in the middle of the bottom of the pressure-resistant shell,and the elastic connecting assembly is connected with the check block. Guide blocks are hinged to the two ends of the saddle correspondingly, guider rods are hinged to the outer sides of the upper portions of the plate belts, guide grooves are formed in the guide rods, and the guide blocks freely slide in the guide grooves. Brake shoe assemblies are evenly distributed on the inner sides of the plate belts at equal intervals, one end of each brake shoe assembly is hinged to the inner side of the corresponding plate belt, and the other end of each brake shoe assembly abuts against the outer circumferential face of the pressure-resistant shell. The brake sticking mechanism is stable and reliable in work.

Description

technical field [0001] The invention relates to the technical field of marine carrying platforms and deep-diving equipment, in particular to a brake mechanism for detachable saddles of deep-sea carrying platforms. Background technique [0002] The deep-sea carrier platform (or non-self-propelled deep-submersible structure) is an important means of ocean development and research. According to different tasks, the deep-sea carrier platform will carry different mission modules. The detachable saddle is used to carry the operating system or equipment on the saddle. [0003] In order to fix the saddle structure, it is usually to form an embrace with the upper saddle by means of a semi-circular bottom hoop, and the bottom hoop and the detachable saddle are pre-tightened by bolts. This structure is simple, easy to install, and low in cost. However, at extreme depths, the pressure shell of the deep-sea carrier platform is subjected to radial shrinkage and deformation under the acti...

AI Technical Summary

Problems solved by technology

This structure is simple, easy to install, and low in cost. However, at extreme depths, the pressure shell of the deep-sea carrier platform is subjected to radial shrinkage and deformation under the action of hydrostatic loads. The bottom moves in an overall translation along the tightening direction. Theoretically, it only touches the local areas of the highest point and the lowest point of the pressure shell. There will be gaps in the remaining larger areas, causing the saddle to loosen, which is likely to have adverse effects on underwater operations.
