Folding and unfolding mechanism of back-unfolding stabilizing fin device

Abstract

A back-retraction fin stabilizer retracting and extending mechanism is mainly used for solving the technical problems of anti-rolling performance improvement. The back-retraction fin stabilizer retracting and extending mechanism is characterized in that an adjusting plate with an adjustable thickness is assembled on a front vertical plate of a fin box; the adjusting plate is correspondingly sleeved on one end of a guide sleeve and is in contact with one end of a slide sleeve in the working position of the fin; another adjusting plate with an adjustable thickness is assembled on the rear vertical plate of the fin box on the other end of the guide sleeve and is in contact with the other end of the slide sleeve in the fin retracting position; and a radical spherical plain bearing is arranged on a retracting and extending connection rod; a rotating arm has a combination structure; and a split-type dustproof ring is adopted. The back-retraction fin stabilizer retracting and extending mechanism is suitable for various back-retraction fin stabilizers.

Description

Technical field:

[0001] The present invention relates to an apparatus for reducing roll of a vessel, and more particularly to an apparatus for reducing the motion of the vessel using hydrofoil action on the surrounding water. Background technique:

[0002] When a ship is navigating in the ocean, it will produce rolling motion under the action of wind and waves. The rolling of the ship will reduce the seaworthiness, damage the hull structure, affect the normal operation of equipment and instruments, and cause the cargo to shift or be damaged by impact. Passengers and crew members are dizzy, severe rolling may also cause danger, and may affect or even lose combat effectiveness on combat ships. In order to reduce ship rolling, the industry adopts various methods, such as bilge keels, anti-rolling water tanks, anti-rolling gyro, anti-rolling Anti-rolling equipment such as heavy hammers and fin stabilizers; with the advancement of technology and the increasing number of high-spee...

Embodiment Construction

[0013] Referring to Figures 1 and 2, the retractable mechanism of the rear retractable fin stabilizer includes a retractable oil cylinder 1, a fin box 2, a sliding sleeve 3, a retractable connecting rod 4, a guide sleeve 5, a rotating body 6 and a locking mechanism.

[0014] The retractable oil cylinder 1 is installed on the front and rear vertical plates of the fin box 2 to drive the movement of the retractable mechanism. The piston rod of the retractable oil cylinder 1 is connected with the sliding sleeve 3 through two push-pull rods, and the retractable oil cylinder 1 is set on the guide sleeve. within 5.

[0015] The fin box 2 is the supporting member of the retractable mechanism. The box body of the fin box 2 and the front and rear vertical plates 20, 20 ′ are welded together with the hull plate to form a closed structure. The front and rear vertical plates 20, 20 Between ', the fixed guide sleeve 5 is stretched, and the insides of the front and rear vertical plates 20, 2...
