Flexible ship body connecting mechanism of combined type semi-submerged ship

Abstract

The invention relates to a flexible ship body connecting mechanism of a combined type semi-submerged ship. The flexible ship body connecting mechanism is characterized in that a ship body connecting direction is set as an X axis and a horizontal direction perpendicular to the ship body connecting direction is set as a Y axis; a joint part of two adjacent ship bodies is divided into a first unit body and a second unit body; a plurality of bearing bases (3) are arranged in the Y direction of the first unit body; tapered pins (2) which are in corresponding fit with the bearing bases (3) are arranged on the second unit body, and each tapered pin (2) is driven by a respective hydraulic oil cylinder (1) to be inserted into or pulled away from the corresponding bearing base (3) in the Y direction, so that the connection and the separation of the ship bodies are realized; the first unit body and the second unit body can oppositely rotate around the tapered pins (2); hydraulic oil cavities (4) with buffer springs (4) therein are arranged on the upper and the lower parts of the first unit body or the second unit body; when the two unit bodies are connected, contact buffer is firstly performed through the hydraulic oil cavities (4), and then the tapered pins (2) are driven to be in locking connection through the hydraulic oil cylinders (1).

Description

technical field [0001] The invention relates to a hull connection structure, in particular to a combined semi-submersible flexible hull connection mechanism, which belongs to the technical field of hull connection. Background technique [0002] The current semi-submersible transport ships generally have the problems of insufficient stability and reserve buoyancy during the dive process, so the risk of performing dive operations is relatively high. Due to the use of the integrated rigid hull of the front hull (including the superstructure space and machinery space) and the rear cargo platform (mainly including the ballast tank), the superstructure will dive, heel or trim along with the main hull, and the crew The working environment is relatively bad, it is easy to cause misoperation, and further increase the danger of operation. [0003] The Chinese patent document whose publication number is CN104002923A discloses a new type of combined semi-submersible transport ship. sa...
