JPS6285796A - Sail equipping device serving also as derick post - Google Patents

Abstract

PURPOSE:To save ship space and reduce cost by utilizing a sailing post serving also as a derick post for cargo work to utilize the sailing post for sailing post itself in sailing and for derick post during the cargo work in anchorage. CONSTITUTION:An approximate laminar flow type hard sail 5 is cut out partially on both left and right upper portion of rectangular sail so that a topping wire 10 at the fixed position does not contact and damage the hard sail 5 operated when a derick boom 9 is fixed. The topping wire 10 passes through pulleys 6, 7 in an out-trigger 8 on the top of a sail post 4 and is introduced in the interior of the sail post therefrom and then from the base 2 of sail past, to a derick winch 12 provided outside the sail post. And the wire is wound and unwound by this winch 12 so that the vertical inclination of the boom 9 is changed to carry out cargo work. Also, in sailing, the sail post 4 is turned left and right about 90 deg. by a turning deice 3 so that the hard sail 5 expands as shown by 5' to help propulsion when getting proper wind.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sail system that uses the mast of a sail system installed on a cargo ship as a support for a derrick post and as part of cargo handling equipment while at anchor.

The mast upper part 4 turns about 90 degrees to the left and right through a turning device 118 attached to the upper deck 1 of the cargo ship in FIG. 1 near the upper end of the mast base 2. Approximately laminar sail 5 is attached to the upper part of the mast 4, and when the wind advances, it is controlled by a 6ζ computer so that it expands like 5' to provide propulsion, helping propel the ship. Helps save energy.

During strong winds, this hard sail 5 is retracted in parallel to the shape shown in Figure 2, reducing wind resistance and improving the stability of the ship, and also retracted as shown in Figure 2 during cargo handling at berth. ,
Turn it 90' and fix it so that it does not interfere with cargo handling. When moored, the mast doubles as a derrick post and is used as part of the derrick equipment.

There is a pulley 6.7 mounted on the top of the mast 4.

The derrick wire 10, whose tip is attached to the derrick boom 9, passes through a pulley 6.7 in the outrigger 8, is guided into the mast 4, is guided to the derrick winch 12 near the mast base 2, and is hoisted and hoisted. At the same time, the derrick boom is rotated to perform cargo handling work.

The hard sail 5 has a topping wire IO when the tip of the derrick boom 9 is fixed on the deck during sailing.
Since this will impede the turning of the hard sail 5, the part that corresponds to the wire 1O should be cut off diagonally like the upper part fpH.

15 is a guy winch, 14 is a guy post, and 16 is a cargo winch.

In this way, the mast installed on a ship serves as a support for the sail system, supporting sail expansion and retraction, and also converts the wind force acting on the sail into propulsive force and transmits it through the ship's hull. . This mast is used to double as a derrick post for cargo handling operations, and is used as a mast during voyage and as a derrick post during cargo handling at anchor.

The shape of the hard sail is such that the upper part of the rectangular sail is partially cut out on both the left and right sides so that the topping wire is not damaged when the derrick boom is fixed due to contact when the sail is operating. The topping wire passes through a swing pulley at the top of the mast, passes through the inside of the mast from the top of the mast, and is led out of the mast from the base of the mast.The wire is wound and unwound using a winch installed outside the mast, allowing the boom to tilt up and down. Since it is a cargo-handling type sail equipment that performs cargo handling work, it saves space on ships and reduces costs, and its effects are very large without losing the original energy-saving effect of the sail equipment.

Claims (1)

[Scope of Claims] A mast installed on a ship serves as a support for a sail device, supports the sail expansion and retraction, and has the function of converting the wind force acting on the sail into propulsive force and transmitting it to the ship's hull. This mast is used to double as a derrick post for cargo handling operations, and is used as a mast during voyage and as a derrick post during cargo handling at anchor. The shape of the hard sail is such that the upper part of the rectangular sail is partially cut out on both the left and right sides so that the topping wire will not be damaged by contact with the fixed position when the derrick boom is fixed when the sail is operated. The topping wire passes through a swing pulley at the top of the mast, passes through the inside of the mast from the top of the mast, and is led out of the mast from the base of the mast.The wire is wound up and unwound using a winch installed outside the mast, allowing the wire to be raised and lowered. A cargo-handling type sail equipment that changes the slope and performs cargo-handling work.
