Two groups of above hydraulic telescopic arms of parallel installation on the energy source boat deck, hydraulic telescopic arm stretches out or indentation to the energy source boat both sides in the vertical direction of the effect lower edge of the hydraulic cylinder hull longitudinal axis.
Be connected with sliding shackle on the wire rope, sliding shackle is connected with buoyancy aid by fixing snap close.
Winch navel formula hydraulic drum winch.
The buoyancy that buoyancy aid produces in water is air gun rifle thick stick and following component weight 2-3 times. exists
The below of hydraulic telescopic arm is equipped with the cable arm.
The utility model is compared with existing air-gun array folding and unfolding mode has following characteristics:
Can realize that by mounting buoyancy aid side hangs, pulls the conversion of form of construction work, simple in structure, reliable operation.
The may command array sinking degree of depth, raising excites quality, widens the sea situation scope of can constructing.
The operating efficiency of towing form of construction work has improved 50% than side machine type, and can construct under more abominable sea conditions.
Side is hung working method and is compared with pivoted arm, takies boat deck length and reduces 40%, can effectively reduce ship length, saves a large sum of boatbuilding cost.
When the drag operation mode is constructed, improve operating personnel's working environment effectively.

Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
Shown in Figure 3, the utility model is fixed on energy source boat 7 decks by column 15, the basic framework of component devices.Each 3-6 group hydraulically extensible arm assembly 2 is installed on framework side by side, and its fixed arm 17 is installed on the framework.Hydraulic telescopic arm 18 is under the effect of hydraulic cylinder, and relative fixed arm 17 is extended and indentation along the vertical direction of the hull longitudinal axis.Below fixed arm 17, settle 6-12 platform navel formula hydraulic drum winch 1.The wire rope 8 of winch 1 is connected with air gun rifle thick stick 4 by fixed pulley 16.The buoyancy aid 9 of ship side both sides respectively is connected with wire rope 8 by the sliding shackle on the static line, and snap close can slide along wire rope 8, and the buoyancy that buoyancy aid 9 produces in water is the air gun rifle thick stick 4 and the following weight of attachment 2-3 times.Buoyancy aid and air gun rifle thick stick 4 are connected by depthkeeping rope 10, and when the sinking degree of depth in air gun 5 water reached depthkeeping rope 10 length, the buoyancy that buoyancy aid 9 produces hung air gun rifle thick stick 4.
Like this, the folding and unfolding of the flexible and winch cable 8 by hydraulic telescopic arm 18 has realized about the air-gun array, the inside and outside two dimensional motion of ship side.In the construction operation, require boats and ships fixedly to navigate by water under the speed of a ship or plane always, buoyancy aid 10 and air gun rifle thick stick 4, air gun 5 and annex thereof are subjected to the percussive action of water always, produced relative hull strength backward, folding and unfolding by wire rope 8, can realize air-gun array with respect to the seesawing of hull, thereby realize the three-dimensional motion of air-gun array in specialized range of air gun source ship 7, satisfy the requirement of operation.
Hydraulic telescopic arm 18 adopts overlap joint to arrange, solved the contradiction of beam of hull and telescopic arm stroke, and built-in hydraulically extensible cylinder has solved the marine corrosion problem in the work progress at sea.
Wire rope 8 adopts not decoupling device method, makes that agility, the reliability of array folding and unfolding effectively improve when the severe sea condition condition is constructed, and has expanded the sea conditions of can constructing effectively.
First pair of telescopic arm 18 of stem direction arranged sway brace as array geometry when the towing mode is constructed, can adjust two spacings between the subarray easily according to sea situation, improved the sea situation adaptability of energy source boat.
As shown in Figure 4, the arm outer end installs hydraulic wireline winch 1 additional, under the power drive that hydraulic power unit provides, the folding and unfolding of the flexible and winch cable 8 by telescoping boom 18, realize about lifting object-air-gun array, the inside and outside two dimensional motion of ship side, thereby satisfied air gun source hangs the mode operation in side requirement.
As shown in Figure 5, mount buoyancy aid 9 after, in finishing the lifting construction mode after the operation steps of sinking air-gun array, continue to display array downwards, at this moment depthkeeping rope 10 relies on the buoyancy of buoyancy aids 9 to hold air-gun array, continues to discharge winch cable 8.Because boats and ships are in navigation, under the impact of water, array lay has gradually arrived the rear of hull.Under the support of front stretching arm 18 and umbilical cable arm 6, the hull rear umbilical cable 3 and the array array shape that maintains requirement.When reclaiming array, according to opposite step operation, the array that can finish towing is recovered on the energy source boat deck.Thereby satisfied the requirement of air gun source ship 7 in the operation of towing mode.
