Abstract

PURPOSE:To unnecessitate to provide on an upper deck any mast that interferes with cargo handling operations, by slidably fitting a rigging boom to a crane boom. CONSTITUTION:The rigging boom 3 is fitted to the crane boom 13, is maintained to be upright by a holder 15, and a lifting rope 14 is reeledup in accordance with the cargo handling operation of a crane 12 so that the rigging boom 3 is lifted up to furl sails 32a-32c. When unfurling the sails, the lifting rope 14 of the crane 12 is reeled out to move the rigging boom 3 so as to unfurl the sails, the holder 15 is released, the crane boom 13 is tilted by the crane 12, and the rigging boom 3 is stored on a storing table. Accordingly, since the sails are furled and unfurled by the cargo handling device and the rigging boom is stored at such a place as not to interfere with the cargo handling operation when handling the cargo, it is unnecessitated to provide on the upper deck any mast that interferes with the cargo handling operations, and the construction cost can be saved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a sailing device for a ship propelled by a sail or a sail and an engine.

Sailing ships, which are propelled by wind power through sailing equipment consisting of masts and sails, declined with the advent of steam engines and internal combustion engines, and at one time were hardly ever put into practical use, but recently there has been a demand for energy conservation. Sailing ships that were propelled only by sails or motorized sailing ships that used a combination of sails and engines were once again in the spotlight.

However, as is well known, sailing ships or mechanical sailing ships have a large number of masts erected on the upper deck. Since the sail is expanded and retracted using the mast and a yard or pool attached to it, it not only increases construction costs, but also requires the mast and sailing equipment, which are not required at all while at anchor, to perform cargo handling. @O There are problems such as problems.

The present invention was made in order to solve these problems.The present invention has been made in order to solve these problems.
li! Another purpose is to reduce construction costs and eliminate obstacles during cargo handling by storing the sailing boom in a place where it will not get in the way during cargo handling.

In order to achieve the above-mentioned object, the present invention provides a crane boot five KJ
It has a sailing boom that is movably attached, and @Takichichi attaches a sailing boom to the crane boom, raises the sailing boom vertically, and extends and retracts the sailing boom with a crane to handle cargo. 4cJr provides a sailing device using a cargo handling device characterized in that the sailing boom is configured to be detachable from a crane boom. The present invention will be explained below using the wJ plane.

Figure #11 is a plan view of the embodiment of the present invention, and Figure #12 is its ll.
There are 11 views C. In both figures, 1 consists of a cargo handling station *@c' provided on the upper deck 2 of the ship, a crane post 11, a crane 12, a crane boom 16, a towing cable 14, etc. 3 is a sailing boom C1 consisting of several booms 31 formed in an arc shape, sails 32 etc. installed between each boom (see Figure 1R4 and Figure 6 1b), and the topmost boom 51d. is provided with a retaining portion (not shown) for a hook provided on the tugging cable 14. Each of these booms 31a
~31d is the support arm 56&~3 as shown in FIG.
3d, each of which is slidably attached to the crane boom 16 via a 3d. In addition, the crane boom 13 is J11
As shown in FIG. 3, the range in which the sailing boom 3 moves is formed in parallel.

The support arm 33.33m of each boom 61 is provided with a boom 31mK1111 section 64 as shown in FIG.
It is attached so that it can rotate by 0 at 6.

To attach the sailing boom 5 to the crane boom 13, the stepped portion 64 of the support arm 36 is brought into contact with one surface of the end of the crane boom 13, and the clamp arm 55 is moved to attach the end of the crane boom 16. After contacting the other side of the lock pin 5, the lock pin 5 locks. As a result, the support arms 35, 53a and the crane boom 13 are attached, and the sailing boom 5 can slide up and down along the crane boom 16. Wear. Note that 4 is a storage platform C for the sail boom 3 provided on the upper deck 2.

A detailed explanation of the present invention constructed as described above is as follows.

In the case of exhibition sails (1) Attach the sailing boom 3 to the crane boom 16.

(21 As shown in FIG. 6 fat, the crane boom 13 is raised by the crane 12 and held vertically by the holding device 15. This holding device 15 is, for example, a component fixed to the crane 12 as shown in FIG. 7. 1 in 16 letter-shaped fixing members
engaging the retaining member 17 fixed to the crane boom 13;
The lock bin 18r is integrally connected to the lock bin 18r.

13+ @ Support arm 34 installed on the lower boom 51a
A defining bin 68 is installed between the stepped portion 64 of the crane 33& and the clamp arm 35, and the boom 51m is fixed to the crane boom 13 (see FIG. 5).

(4) Engage the hook set at the tip of the hoisting cable 14 of the crane 12 with the retaining part provided on the boom 51d of the first JLR.

15J Crane 12 cargo handling 14 according to the work
The sails 32a to 62C are expanded by hoisting the tube and pulling up the sailing boom 3.

(6) The angle of the sailing pool 30 relative to the wind is adjusted using the swinging function of the crane 12.

(7) When sailing with the sails retracted during strong winds, the lower boom 31aj9, the next stage, the third stage, and the pooms 31-31d are lowered as appropriate and fixed to the crane boom 13 with the fixing pin 38.

In the case of sailing and cargo handling work (1) When the crane 12 is hoisted, the cable 14 is let out and the sailing boom 3 is sailed as shown in Figure 6, Figure 1.

+23 Release the holding device 15 and lower the crane boom 16 using the crane 12.

(31 Pull out the fixing bin 68, remove the lock bin 67, rotate the clamp arm 65 to the position IC indicated by the two-dot chain line as shown in FIG. Then, the sailing boom 6 is stored in the storage platform 4.

(4) From this K, cargo handling equipment/11 is used for the original cargo handling work,
1 can be done.

In the above explanation, the case where the sailing boom storage platform is provided on the upper deck adjacent to the cargo handling equipment is shown, but it may be provided in other locations. In addition, embodiments of the mounting mechanism and fixing mechanism of the sailing boom to the crane boom, the vertical holding device of the clay/boom, etc. have been shown, but these mechanisms are not limited to this embodiment, and are not limited to the gist of the present invention. Various mechanisms can be applied without departing from the above. In addition, as is clear from the fact that the sails installed between each boom are soft sails and steel piles, both C are ↓ and 0 or more, the present invention is able to mount the sails using cargo handling equipment that is not used during the voyage. In addition to installing a boom and expanding and retracting the sails from the IK, the sail boom was stored in a place where it would not get in the way of cargo handling operations, so the upper deck would not get in the way of cargo handling operations. There is no need to provide a second strike, and the cost of construction can be reduced, so implementation will have a great effect.
