本発明は俯仰式ジブクレーンを有する起重機船に関する
もので、特に大型起重機船に適するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hoist ship having an elevating jib crane, and is particularly suitable for a large hoist ship.

ヂ仝の操作によって俯仰自（［にしである。q (Figures 1 and 2 show an example of a conventional hoist ship. In the figure, 1 is the hull, 2 is a jib whose base is pivoted to the bow, and 3 is a ship on the hull l behind the jib 2. A fixed back tower, 4 is a winch installed behind the back tower 3, a pulley 6 pivots the cable 5 of this winch 4 to the top of the back tower 8, and a pulley installed at the tip of the jib 2. 7,
Then, the jib 2 is moved to the win by swinging it over the pulley 8 provided at the top of the back tower 8 and fixing the cable end.
It is possible to look down and look down by the operation.

より、フック９、ｌＯが昇降するようになっている。9 and 10 are hooks suspended from the tip of the jib 2 via pulley devices 11 and 12, respectively; 18.1
Reference numeral 4 indicates ropes of pulley devices 11 and 12, which are respectively wound around winches 15 and 16 installed inside the hull 1. Therefore, by operating these winches 15 and 16, the hooks 9 and 10 are raised and lowered.
しかしてこのような起重機船を回航する場合に、橋梁下

の従来の起重機船では、バックタワー３の頂部の高さが
起重機船の最大高さとなる。しかして従来の大型起重機
船ではこの高さが四十故米以上もあったため、これを三
十米以下にしたい要望がある。However, when such a hoist ship needs to pass under a bridge, the overall height of the hoist ship becomes a problem. In this case, the height of the jib 2 can be made considerably lower by folding the jib 2, but in a conventional hoist ship with a fixed bank tower 3, the height of the top of the back tower 3 is the maximum height of the hoist ship. However, since conventional large crane ships had a height of more than 40 meters, there is a desire to reduce this height to less than 30 meters.
本発明はこのような要望を満足させるためになされたも

ることを目的とするものである。The present invention was made to satisfy these demands, and by making the back tower of a hoist ship foldable, the overall height of the hoist and ship during voyage can be lowered, making it possible to construct bridges that were previously impossible. By making it possible to pass underneath, the purpose is to expand the range of use of the hoist ship, and also to lower the center of gravity of the hoist ship when turning, thereby improving the stability of the ship.

In this embodiment, two sets of jibs 2 are shown arranged side by side, but since the left and right sides have the same structure, only one side will be explained.

ィンチで、甲板ｌａ上に設置しである。As shown in detail in FIGS. 6 and 7, the present invention connects the lower end of the front leg 81 of the back tower 3 to the bracket 32 protruding from the deck ial by a pin 33, and the rear leg
The two-part link 34 and the lower link 35 are formed to be bendable by a connecting pin 36, and the upper end of the upper link 84 is connected to the upper part of the front leg 31 by a pin 37.
The lower end of the lower link 86 is connected by a pin 89 to a bracket 88 protruding from the deck la, and a vehicle device +40 is provided at 7 between the upper part of the lower link 86 and the stern deck 18. 40a is a pulley pivoted on the lower link 35 side, and 4ob is a pulley pivoted on the deck la side? 17 wheels, 4oc are these pulleys ΦOa, 4
The cable 41 that was stretched over the cable 0b is a winch that wound the cable 400, and was installed on the deck la.
つぎに上述のように構成した本発明起重機船の作用を説
明する。Next, the operation of the hoist ship of the present invention constructed as described above will be explained.
すなわちこの起重機船を回航したり、または荒天時等に
際して船の安定を高める場合、特に橋桁の高さが十分で
ない橋梁下を通過する時には、ジブ２を水平に近く倒す
と共に、バックタワー８を折りたたむ。In other words, when turning this hoist ship or increasing the stability of the ship during stormy weather, especially when passing under a bridge whose girder is not high enough, the jib 2 should be brought down nearly horizontally, and the back tower 8 should be folded down. .

、橋梁下、の通過を容易にすることができる。To fold the bank tower 3, the winch 4 shown in FIG. 6 is operated to let out the entire cable 5, and the pulley device 4.0 is shortened by winding the cable 400 with the winch 41, thereby forming the back tower 3. Each component profit 81
, 84.35 are displaced and folded low as shown by two-dot chain lines 31', 84', and 35'. Therefore, by shifting in this manner, the overall height of the hoist ship can be further reduced, making it easier to pass under the bridge.

いうすぐれた効果が得られる。As described above, the present invention makes the back tower of the hoist ship foldable. Accordingly, when turning or in rough weather, the back tower can be folded to lower the overall height of the hoist ship. It is said that it is possible to pass under bridges that could not be passed in the past, expanding the scope of use of hoist ships, and at the same time, by lowering the rlt center of the hoist ship when turning, it is possible to improve the stability of the ship. Excellent results can be obtained.
