Problems solved by technology

Such a situation causes the survival craft or the rescue boat to be in a state of violent swinging before the davit flips out and begins to fall. In addition to the discomfort caused by the bumps and swings, it also increases the danger.
In order to reduce the amplitude of the sway, various davit manufacturers have designed some anti-sway structures and devices, whi

Embodiment Construction

[0015] The base 1 is installed on the same deck plane as the boat frame, the base 1 is provided with a first hinge shaft 7 and a second hinge shaft 8 in the vertical direction, and one end of the main link 2 is fixed to the base 1 through the second hinge shaft 8 Link, one end of the auxiliary connecting rod 4 is fixedly linked with the base 1 through the first hinge shaft 7; Respectively linked, base 1 and main connecting rod 2, secondary connecting rod 4, anti-sway bar 5 constitute parallel four-bar linkage like this.

[0016] The first hinge axis 7, the second hinge axis 8, the third hinge axis 9 and the fourth hinge axis 10 form four vertices of a parallelogram, and because the third hinge axis 9 on the base 1, the fourth hinge axis 10 is perpendicular to the deck In the direction, so with the third hinge axis 9, the fourth hinge axis 10 and the main connecting rod 2, the anti-sway bar 5 connected by the secondary connecting rod 4 is just perpendicular to the deck all the ...

Abstract

The invention relates to an anti-swing device of a lifeboat davit, and provides a mechanical-connecting-rod-type anti-swing device applied to the lifeboat davit, aiming to solve the problem that existing anti-swing devices with good effect are high in cost and complex in design while the same with simple structure and low cost are poor in effect. The mechanical-connecting-rod-type anti-swing device comprises a base (1), a main connecting rod (2), an auxiliary connecting rod (4), an anti-swing retaining rod (5) and a drive connecting rod (3). The mechanical-connecting-rod-type anti-swing device is characterized in that the drive connecting rod (3) is connected with the main connecting rod (2), and a parallel four-connecting-rod mechanism is formed by the base (1), the main connecting rod (2), the auxiliary connecting rod (4) and the anti-swing retaining rod (5). A parallel four-connecting-rod principle is applied, a davit body serves as a power source, the mechanical-connecting-rod-type anti-swing device follows the davit passively, and a pushing rod with a rubber board is ensured to cling to a hull at any position during turning-out of the davit, so that the objectives of protecting a lifeboat and reducing swing amplitude are effectively achieved.

Description

technical field [0001] The invention relates to a lifeboat davit, in particular to an anti-sway device for a lifeboat davit. Background technique [0002] According to Chapter VI of the 1974 International Convention for the Safety of Life at Sea (SOLAS), the lifeboat davit equipment should be able to safely land its equipped survival craft or rescue boat under adverse conditions of trim 10° and heel 20°. Capable of providing satisfactory evacuation in Beaufort 6 sea conditions. Such a situation has caused the survival craft or the rescue boat to be in a state of violent swaying before the davit is turned over and before it starts to fall. In addition to the discomfort caused by the turbulence and swaying, it also increases the danger. In order to reduce the amplitude of sway, each davit manufacturer has designed some anti-sway structures and devices. Basically, there are many structures of hydraulic cylinders, and it is represented by designing several cylinders similar to...
