Abstract

Riešenie sa týká stabilizačného závěsu lodnej nástavby pozóstávajúcej aspoň z dvoch konzol. Každou konzolou prechádza nejmenej jedno zvislé tiahlo, ktoré je na hornom konci opatřené závitom a maticou pre výškové nastavenie polohy nástavby a na spodnom konci opatřené osadením s pružinou, nasunutou na tiahlo. Na horný koniec pružiny dosadá opěrný výčnelok, ktorý je upevnený k lodnej nástavbě. Opěrné výčnělky sú upevněné k nástavbě nad rovinou jej ťažiskaThe solution concerns the stabilizing hinge of a ship's superstructure consisting of at least two consoles. At least one vertical rod passes through each bracket, which is equipped at the upper end with a thread and a nut for height adjustment of the superstructure and at the lower end equipped with a fitting with a spring, pushed onto the rod. A support protrusion rests on the upper end of the spring, which is fixed to the ship's superstructure. The supporting protrusions are fixed to the superstructure above the plane of its center of gravity

Description

The solution relates to a stabilizer suspension of a superstructure consisting of at least two consoles. At least one vertical rod extends through each bracket and is threaded at the upper end and a body positioning nut is provided at the lower end and a spring-loaded shoulder is provided at the lower end. At the upper end of the spring there is a support projection which is fixed to the ship superstructure. The support projections are fixed to the superstructure above the plane of its center of gravity.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stabilizer hinge for a superstructure comprising at least two brackets, wherein each bracket extends at least one vertical rod which is threaded at the upper end and a nut for sliding the rod in the bracket, the lower end of the rod being provided with a shoulder the spring is pushed onto the rod, where the upper end of the spring abuts the support projection which is fixed to the ship superstructure.

Boat superstructures are often mounted on spring washers or spring blocks. The aim is to eliminate the transmission of vibrations and structural noise into the body space. Solutions are known with flexible blocks placed under the superstructure floor structure. The limitation of vibration transmission is d, sF, using flexible blocks of low stiffness and large stroke. The tilt of the ship then leads to additional tilt of the superstructure. The superstructure must be fixed to the hull by a massive securing mechanism that transfers vibrations to the body from the hull. Additional tilt and vibration transfer reduce the effect of flexible mounting of the superstructure.

The aforementioned drawbacks are eliminated by the stabilizing suspension of the ship superstructure according to the invention, the principle of which is that the support projections are fixed to the superstructure above the plane of its center of gravity.

The solution makes it possible to use a spring of very low stiffness and to achieve a practical exclusion of the transmission of vibrations and noise through these springs from the hull to the superstructure.

The solution makes it possible to exclude the massive stabilizing mechanism of the superstructure, which would transmit noise and vibration from the hull to the superstructure.

With a sufficient height of the support projections above the body center of gravity plane as well as 6 β when the weight distribution of the superstructure changes due to the transition of the axles or the relocation of the stock, said advantages are not lost. The result is a radical reduction in vibration and noise compared to the known cases where the flexible blocks are located below the superstructure floor. An exemplary embodiment of the stabilizer hinge of the superstructure of the invention is shown in the drawing, wherein FIG. 1 shows a side view of the stabilizer hinge and FIG. 2 is a cross-sectional view of the stabilizer hinge when the ship is tilted.

The superstructure stabilizing hinge 6 consisting of at least two brackets 1 with apertures. At least one vertical rod 2 extends through each bracket 1, having a threaded upper end and a nut 3 for positioning the superstructure position B. The lower end of the rod 2 is provided with a shoulder 8 on which the spring 4 is pushed onto the rod 2, where the upper the end of the spring 4 abuts a support projection 5 which is fixed to the ship superstructure 6, characterized in that the support projections 5 are fixed to the ship superstructure 6 such that the weight of the superstructure 7 is below a plane folded over the support projections 5.

In the tilt of the hull, the hung S is tilted less than the hull. The springs 4, which can carry the superstructure more than ten times lower than the resilient blocks located under the floor of the body C. In fact, the frequency of the oscillations can be substantially lower than the vibrations of the mechanisms in the hull, which is virtually impossible to carry into the body. . It is therefore a vibration separation of the superstructure 8.
