Description

[Detailed description of the invention] The present invention relates to a detachment storage device for a small ship such as a rescue boat or a work boat. The purpose is to allow it to be stored on board the ship.

Conventionally, a boat is detached from or stowed away from a ship by unhooking it from a hook at the tip of a cable attached to a crane or davit on the side deck, but boats floating on the sea surface are easily moved by waves. While it constantly moves up and down,
Since the hook for hanging the davit or crane is in a substantially fixed position (the movement of the ship due to wave motion is extremely small compared to the movement of the boat), it is extremely difficult to unhook the hook from the boat. Assembling work is unstable and extremely dangerous due to collisions with hooks, etc.

With this in mind, the present invention is designed to facilitate the work of detaching and storing the boat by allowing the boat support part to move up and down following the movement of the boat due to wave motion. However, a suspension frame equipped with a paper support that supports and releases the boat by expanding and contracting is pivoted to the free end of an arm that is vertically swingably attached to one side of a davit installed on the upper side of the deck, and the other A rescue boat that is suspended from a davit by a cable, one end of which is fixed to a gate frame by bypassing a detour trochanter at one end of a cylinder that follows wave motion, and the other end is wound around a winch. etc., in a detachable storage device.

To explain in detail the embodiment shown in the figure, 1 in the figure is a follower side davit, 2 is an arm support side davit, and a cylinder 5 is placed on the ship's side deck 3 in a direction perpendicular to the side, guided by a rail 4. , 5' are arranged in parallel so as to be driven and moved by.

Reference numeral 6 denotes a paper support, with gripping arms 7 and 7' facing each other at an interval of at least the width of the boat, the base end of which is connected and supported to a support box 8 in which an expansion/contraction hydraulic cylinder Z- is housed, and is also gripped. arm 7,7
' have side support arms 9, 9' and boat bottom support parts 10, 10'.
The paper support 6 is housed in a similar manner within a gate frame 11, and a support box 8 is attached to a horizontal beam of the gate frame.

Reference numeral 12 denotes a support arm, one end of which is pivotally attached to the arm support side davit 2 so as to be vertically swingable, and the other end of which is attached to the gate frame 11.
It is pivoted to.

13 is a follower cylinder, which is fixed to the support column 14 of the follower davit 1.

15 is a suspension cable, one end of which is fixed to the gate frame 11;
The other end is wound around the winch 17 by bypassing the trochanter and the bypass trochanter 16 of the follower cylinder 13.

In the figure, 18 is a boat, 19 is a buffer material, and 20 is a wave detection tube.

The device of the present invention configured as described above is normally stored on the ship's side deck, and when used, it is
', the following side davit 1 and the arm support side davit 2
Move the boat toward the side to position the boat facing the sea surface.

After that, loosen the suspension rope 15 wound around the winch 17,
The boat 18 is lowered onto the sea surface.

When the boat 18 is floating at its lowest point above the sea surface, the winch 17 is fixed and the following cylinder 13 is put into operation.

The tracking cylinder 13 expands and contracts by a hydraulic pump driven by a signal sent to the hydraulic pump from a wave detection tube 20 that detects the pressure inside the pipe that fluctuates due to wave motion, and comes to follow the wave motion of the sea surface.

Since the boat that has been lowered onto the sea surface is gripped by the paper support 6, the expansion/contraction cylinder part B of the paper support is then driven to expand the gripping arms 7, 7' and release the boat 1B. .

If you want to store the other parts, do the reverse of the above.

That is, after manipulating the boat to position it within the paper support 6 that moves up and down on the sea surface in addition to the wave motion, the expansion/contraction cylinder part 8 is driven and gripped, and the suspension rope is wound up with a winch. The boat is hoisted up and both davits are moved away from the side to complete storage.

In addition, the means for horizontally moving both davits include rack and pinion, rope tension, etc., and the means for detecting wave motion include:
There are methods that use phototubes and floats.

As mentioned above, since the paper support is suspended from the davit in a state that follows the wave motion, the paper support follows and synchronizes with the movement of the boat that moves up and down due to the wave motion, and the relative relationship between the boat and the paper support is adjusted. To eliminate target movement and to quickly and safely remove and store a boat without causing dangers such as collisions with paper supports by workers, rescuers, and rescued persons on board the boat.

Also, by following, rescue operations can be carried out in any weather.

Claims (1)

[Scope of utility model registration request] A vertically swingable arm is attached to one side of a davit installed so that it can slide horizontally on the upper side of the ship's deck, and a poor-quality gate-shaped suspension frame equipped with a wave detection tube is pivoted to the free end of the arm. The inferior suspension frame is suspended from the other davit by a cable, and the cable is wound up by a winch via a follower cylinder that operates by following the waves in response to a signal from the wave detection tube. , a detachment and storage device for a rescue boat, etc., in which a paper support to be supported and released is supported by an expanding and contracting cylindrical frame within a poor-quality hanging frame.
