Abstract

PURPOSE:To improve safety for transshipment between a ship and a small boat, by installing a crew boarding-alighting frame free of movement from the ship via a link mechanism while controlling this frame so as to follow up motions of the small boat. CONSTITUTION:A stanchion 2 is erected on a deck of a ship 1 by a turning mechanism free of rotation around the shaft. A crew boarding-alighting frame 5 is connected to this stanchion 2 via links 3 and 4. Each of these links 3 and 4 and the frame 5 are made to rotate around each of pivoting points 3b-5b by each of hydraulic cylinders 3a-5a. In addition, a light source 11 is erected on a small boat 10, while a light receiving part 15 is set up on the frame 5. And, the light receiving part 15 receives light out of the light source 11 whereby each hydraulic cylinder is controlled so as to cause the frame 5 to follow up motions of the small boat 10.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Sedentary Occupational Use) The present invention relates to a device for boarding and disembarking passengers on the hulls of ships and other marine structures.

(Conventional technology 1 problem) When a ship is away from the quay in a port or is stopped on the ocean outside the bay, or when a crew member or the like boards or disembarks the ship due to a change of duties in the hull of each Kaji Kaihai structure on the ocean. In such cases, a small boat is used between the hull and land, and a side ladder (g) is installed on the hull (g) as shown in Figure 5.
A) is installed, and boarding and disembarkation between the small boat (C1 and the hull (α) is carried out by ascending and descending the ship's side ladder (A) and transferring between the two. However, if the waves are large, the small boat (C1
There is a problem in that the passengers may be unable to get on or off the ship due to the large amount of movement, making it extremely dangerous to transfer to and from the ship's side ladder (b).

(Means for Solving Problem 1 of the Invention) The present invention has been developed in view of the above-mentioned circumstances, and includes a pillar installed on the deck of a ship that can be rotated, and a pillar that can be rotated. a link mechanism that is pivotally connected to and extends from the top and is operated vertically and telescopically; a pedestal for boarding and disembarking passengers that is pivotally connected to the tip of the link mechanism and swings; and a frame that receives light emitted from a small boat. The boat is characterized by a configuration including a pedestal control mechanism that outputs a positional deviation signal with respect to the pedestal and controls at least the vertical and telescopic mechanisms of the link mechanism and the swinging mechanism of the pedestal to control the pedestal to follow the small boat. A platform for passengers to board and disembark is movable from the hull via a support and a link mechanism, and the platform is controlled to follow the small boat using light emitted from the small boat, thereby making it possible to transfer between the hull and the small boat. The object of the present invention is to provide a boat boarding and disembarking device that significantly improves safety and eliminates the above-mentioned problems.

(Embodiment of the invention) An embodiment of the present invention is shown in FIGS. 1 to 4,
In Fig. 1, (1) is the hull, and a pillar (2) is erected on the deck of the hull (1), and the pillar (2) is equipped with an appropriate rotation mechanism (electrically controlled motor) (2 cL ) so that it can be rotated around the vertical axis,
The first link (3) of the column (2) K is pivoted (3b) so as to be able to rise and fall freely, and a hydraulic cylinder (3α) is connected between the column (2) and the first link (3). A second link (4) is pivotally attached (4b) to the tip of the 11th J link (3) in a vertically undulating manner, and a hydraulic cylinder (4b) is connected between the first link (3) and the second link (4). 4α) is connected to the second link (4), and a frame (5) for passengers to get on and off is swingably pivoted to the tip of the second link (4) via a projecting arm.
5b), a hydraulic cylinder C3 (L) is connected between the second link (4) and the pedestal (5), and the first rotation mechanism (2α)
When the pillar (2) is rotated by the link mechanism (3)
, 4), the pedestal (5) can be moved in a horizontal plane;
Hydraulic cylinder (3g) (link mechanism (3,
4) is composed of a vertical and telescopic mechanism (3cL, 4α) that vertically and vertically extends and retracts the hull (1) K, and a hydraulic cylinder (5α) that swings the mount (5) in response to the movement of the link mechanism. It is configured with a swinging operation mechanism (5α) that always holds it vertically.

Furthermore, a light source aυ is installed upright on the small (traffic) boat ull, and a light receiving part a9 is arranged on the mount (5), and as shown in Figure 2, the light source of the small boat uni is installed. The projected light (11α) emitted from Ql) is imaged as a point image (11') on the light receiving element (15b) via the condensing lens (15cL) of the light receiving part a9, and the point image (11') is formed on the light receiving element (15b). (11') and the optical axis (1SC) is detected using positive and negative minute voltages, and the deviation detection signal (15j) is amplified by an amplifier, and the position between the small boat (1G and the mount (5) The configuration is such that it is output as a deviation signal (23α).

Further, the hydraulic cylinders (3α), (44) and (5

By switching with the control-like mechanism, the column, the link mechanism, and the pedestal are operated, and the pedestal is moved to a desired position on the hull or on the sea surface.

(Operations and Effects of the Invention) As described above, in the present invention, the manual operation mechanism rotates the support column, moves the link mechanism up and down and expands and contracts, and swings the pedestal, so that the pedestal can be moved to the deck of the ship. It can be operated upwards or on the sea surface near small boats, and
When the cradle control mechanism is activated, it is possible to have the cradle follow the small boat up and down under at least automatic control, and automatic control in the horizontal plane is also possible, making transfer between the hull and the small boat extremely safe and quick.
