Description

Technical Field

[0001] The utility model relates to a lifeboat bracket, in particular to a foldable lifeboat bracket for ships. Background Art

[0002] A lifeboat is a special lifeboat installed on a ship to rescue passengers in the event of a shipwreck. It is propelled by rowing, sailing, or a power engine. An air box is often installed in the boat so that the boat still has enough buoyancy after taking on water to ensure the safety of the boat and the people on board. The lifeboat of a seagoing ship is also equipped with a certain amount of fresh water, food, and daily necessities. The davit is a special ship-borne equipment used to load and unload lifeboats or workboats. It is generally located on both sides of the ship's deck. It is usually inside the ship's side and is extended out of the side to lift or lower the boat when in use. According to the different ways in which the davit transfers the boat from the inside to the outside of the side, it is divided into four types: transfer type, tilt type, gravity type, and free fall type. The design and use of free-fall lifeboats greatly simplify the release procedures and steps compared to other types of lifeboats. In times of crisis, distressed crew members can leave the ship more quickly, increasing their chances of survival. This type of lifeboat is mainly arranged at the stern of the ship. Depending on the different boat-holding devices on the davit, it is divided into two types, namely, the pressure plate type and the heavy hammer hook type.

[0003] However, the pressure plate type davit has obvious disadvantages: the boat pressing device is stuck and cannot rotate freely; the control cable of the boat pressing device is missing; the return spring of the boat pressing device fails, etc., which leads to the failure of the boat pressing device. Although the boat pressing device is only a small object on the free-fall lifeboat davit, it is easy to be overlooked in normal times, and because its installation position is usually in a place that is difficult for personnel to reach, it is very difficult to maintain, so various defects on the boat pressing device are often found. Although the boat pressing device is small, if it fails, the hidden dangers should not be underestimated, which will eventually lead to the failure of the free-fall lifeboat to enter the water and the crew to miss the opportunity to escape.

[0004] In view of this, the utility model aims to provide a foldable lifeboat bracket for ships. Utility Model Content

[0005] The main purpose of the utility model is to provide a foldable lifeboat bracket for ships to solve the defects mentioned in the above background technology.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A foldable lifeboat support for ships comprises a lifeboat chassis, wherein one end of the lifeboat chassis with a hook is fixed on the deck through a leg, and the other end of the lifeboat chassis without the hook is connected to the deck through a hinge; the leg is an electric telescopic rod, and the other end is respectively fixed to the two ends of a vertical rod with a hook, and a button is provided on the surface of one leg; the two ends of the vertical rod are respectively fixed to two cross rods, and a plurality of vertical rods are evenly distributed at the bottom of the cross rod; linear slide rails are respectively provided on the cross rod; the hook is fixed to the middle part of the vertical rod at one end, and the hook opening faces the other end of the cross rod.

[0008] As a preferred technical solution of the utility model: a lifeboat hanger is fixedly provided on the front side of the lifeboat chassis, a turntable is provided at the bottom of the lifeboat hanger, one end of the turntable is fixedly connected to the deck, and the other end is fixedly connected to the gravity arm.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The foldable lifeboat support for ships is provided with a hydraulically retractable outrigger, and the angle of the inclination direction of the lifeboat chassis is adjusted by controlling the extension and retraction of the outrigger. When the lifeboat needs to be parked, the outrigger is lowered so that one end with the hook is lower than the other end, and the lifeboat slides toward the hook end along the slide rail under the action of its own weight. When the lifeboat slides to the hook, the hook will jam the slot at the bottom of the lifeboat, stopping the lifeboat from sliding and finally being fixed on the lifeboat chassis; when the lifeboat needs to be lowered, the retractable outrigger is raised, and the lifeboat chassis tilts in the opposite direction. When it tilts to a certain angle, the thrust provided by the lifeboat's own weight is greater than its friction, and the slot at the bottom of the lifeboat automatically disengages from the hook, and the lifeboat moves toward the vertical rod without the hook, slowly disengages from the lifeboat chassis, and continues to rush to the sea under the action of inertia, taking the crew with it to escape.
