Description

Lifting type boat folding and unfolding device

Technical Field

The utility model relates to the technical field of ship body lifting devices, in particular to a lifting type boat folding and unfolding device.

Background

At present, the skiff collecting and releasing device of domestic active service boats and ships configuration has two major types, and one type adopts slide formula collecting and releasing device, and this type of device needs the skiff navigating mate through observing and adjusting and the relative position with the stern portion slide, then needs the crew to hand the terminal couple of traction rope and establishes reliable connection with the skiff, leads the skiff to the ship completely through traction rope, and whole recovery process is discontinuous, and operating efficiency is low, and personnel pull the couple operation and have the safety risk to operating the crew. When the boat is released, after the hook is released, the boat enters water under the action of self weight, the sliding speed can be gradually increased, the boat can have large impact force when entering the water, and the whole process is not stable.

The other type is a hoisting type retraction device, a boat is hoisted by a deck crane on the boat, the boat is transported to the water surface in a rotating way, and then a steel wire rope is released to vertically release the boat to the water surface. During recovery, the boat is lifted by a lifting hook of the deck crane, and the boat is transported to the deck surface in a rotating way. Whether the boat is released or recovered, the whole process is easily influenced by strong wind and sea waves, so that the boat swings in the air, and is damaged by collision and the like.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a lifting type boat collecting and releasing device which is simple in structure, stable and safe.

The technical scheme adopted by the utility model is as follows: the ship comprises a ship body, a supporting platform, two groups of slide rails, pulleys and a winch, wherein the supporting platform is arranged on one side of the ship body, the two groups of slide rails are arranged on a ship board of the ship body, the supporting platform is connected with the two groups of slide rails in a sliding mode, the pulleys are arranged on the ship body, the winch is fixedly connected with the ship body, and a steel wire is drawn out by the winch to wind the pulleys and drive the supporting platform to slide up and down.

Furthermore, a first limiting part and a second limiting part are arranged on the slide rail, the first limiting part is arranged at the lower end of the slide rail, the second limiting part is arranged at the middle part of the slide rail, and the supporting platform slides between the first limiting part and the second limiting part.

Further, the winch is provided with a motor drive.

Further, the supporting platform is of a net structure.

Furthermore, a reserved groove is formed in the sliding rail, and a protruding block matched with the reserved groove is arranged on the supporting platform.

Furthermore, the middle part of the pulley is provided with a groove matched with the steel wire.

The utility model has the beneficial effects that: the utility model adopts a lifting design, comprises a supporting platform, a sliding rail and a winch, vertically lifts when the boat is recovered, has simple structure and convenient assembly, reduces the cost of daily maintenance, and adds a pulley structure to perform steering operation on the steel wire, thereby avoiding direct contact between the steel wire and the boat body and prolonging the service life.

Detailed Description

As shown in fig. 1 to 5, in this embodiment, the present invention includes a hull 1, a supporting platform 2, two sets of slide rails 3, pulleys 4, and a winch 5, where the supporting platform 2 is disposed on one side of the hull 1, the two sets of slide rails 3 are disposed on a side of the hull 1, the supporting platform 2 is slidably connected to the two sets of slide rails 3, the pulleys 4 are disposed on the hull 1, the winch 5 is fixedly connected to the hull 1, the winch 5 draws out a steel wire to wind the pulleys 4 and drive the supporting platform 2 to slide up and down, and a relief opening adapted to the supporting platform 2 is disposed on the hull 1. Adopt over-and-under type design, including supporting platform 2, slide rail 3 and capstan winch 5, vertical lift when the skiff is retrieved, simple structure equipment is convenient, reduces the cost of routine maintenance to add 4 structures of pulley and turn to the operation to the steel wire, avoid the direct contact between steel wire and the hull 1, increase of service life.

In this embodiment, the slide rail 3 is provided with a first limiting member 6 and a second limiting member 7, the first limiting member 6 is disposed at the lower end of the slide rail 3, the second limiting member 7 is disposed at the middle portion of the slide rail 3, the supporting platform 2 slides between the first limiting member 6 and the second limiting member 7, and the first limiting member 6 and the second limiting member 7 are both plate-type structures. The first limiting part 6 and the second limiting part 7 are added to limit the up-and-down sliding position of the supporting platform 2, so that the effect of folding and unfolding the boat due to the influence of the excessive displacement of the supporting platform 2 is avoided.

In this embodiment, the winch 5 is provided with a motor drive. The design of the motor-driven winch 5 is adopted, the cost of manual recovery is reduced, and the retraction efficiency is improved.

In this embodiment, the support platform 2 is a net structure. The boat is supported by adopting drainage, so that the resistance of water in the folding and unfolding processes is reduced, and the running efficiency is improved.

In this embodiment, a preformed groove is provided in the slide rail 3, and the supporting platform 2 is provided with a projection adapted to the preformed groove.

In this embodiment, the middle of the pulley 4 is provided with a groove matched with the steel wire. The groove design is added into the pulley 4, so that the steel wire can smoothly run under the guiding action, and the steel wire is prevented from directly contacting the ship body 1.
