Description
Technical field
The present invention relates to technical field of ships, particularly a kind of vertical lifting of all-around mobile reamer arm is dredged from strand suction of navigating
Ship.
Background technology
Existing cutter suction dredger is mainly by main hull, bow piling bar chassis（Main piling bar chassis and auxiliary piling bar chassis）、
The part such as stern crane span structure and superstructure living area forms.Portal structure is connected by connecting shaft with main hull structure, crane span structure
Structure can rotate around connecting shaft relative to main hull.Stern crane span structure end set reamer head, passes through reamer head Rotation Dredging.Digging
When mud boatman makees, stem piling bar chassis is to seabed（River bed）Stretch out piling bar, fixed hull；Crane span structure is according to seabed（River bed）Depth with
Certain angle and sea bed（Riverbed）Contact；Stern casts anchor to both sides, by drawing anchor that dredger can be made to carry out fan-shaped swing；Rotation
Reamer head is dredged.Piling bar chassis can move forward and backward dredger by hydraulic mechanism.
Piling bar chassis equipment volume is huge, influences the sight of dredger driver's cabin, dredger safety is present when navigating by water hidden
Suffer from.Dredger moves forward and backward by piling bar chassis, and movement can not be continuous, influences dredging efficiency.And the equipment of piling bar chassis is made
Valency is costly, directly results in the increasing of dredger construction cost.
Portal structure tilts and sea bed（Riverbed）Contact, so the length of portal structure causes bridge much larger than depth of dredging
The weight of frame structure is very heavy.Portal structure is connected by connecting shaft with main hull, it is desirable to which main hull and portal structure are connecting
Axle surrounding need to design many reinforcements, directly results in the increase of dredger light weight, reduce the operation economy of dredger
Property.
Dredger realizes that the fan-shaped of hull swings by casting anchor, and is weighed again after ship moves forward certain distance, it is necessary to receive anchor
Newly cast anchor.This process not only wastes time and energy, and causes the process of dredging continuous, and dredger can not be whole under prior art
Body transverse shifting.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, there is provided one kind solve existing cutter suction dredger sight it is bad,
Cost is high, it is discontinuous to dredge, can not overall transverse shifting, the problems such as ship light weight is larger, reach and improve ship and dig
Mud efficiency, the vertical lifting of all-around mobile reamer arm of the purpose of shipbuilding cost is reduced from the cutter suction dredger that navigates.
The technical solution adopted by the present invention is：
A kind of vertical lifting of all-around mobile reamer arm is from navigating cutter suction dredger, including main hull and the life for being arranged on main hull
Area, its innovative point are：The intermediate region of the main hull sets moon pool, reamer arm support structure in the moon pool, the strand
Reamer arm movable up and down is set in tool arm supporting construction, and the bow of the main hull is provided with stem sideways-acting propeller, institute
The stern for stating main hull is provided with ship stern all-direction propeller, and the main hull bottom is provided with flexible propeller, and described stretch pushes away
Entering device can be turned round with 360 ° omni-directional.
Further, the living area is arranged in main hull first half.
Further, the reamer arm support structure mechanism containing heave compensation.
Further, the flexible propeller is located on the cross central line of main hull bottom.
Further, the sideways-acting propeller, all-direction propeller and flexible propeller are satisfied by meeting DP3 dynamic positionings
Requirement.
Beneficial effects of the present invention are as follows：
It is of the invention novel in design, safe and reliable.Due to present invention eliminates piling bar chassis, ship moved by propeller and
Positioning, reduces shipbuilding cost, improves the economy of ship.Present invention eliminates the portal structure positioned at ship stern, ship is changed to
The reamer arm of intermediate vertical motion, ship deadweight is alleviated, can reduce the master of ship while dredging efficiency is met
Yardstick, further improve the economic performance of ship.Living area is arranged in main hull first half, improves regarding for ship wheel house
Open country, reduce the probability caused danger during ship's navigation.By propeller movement improve ship can only fan shape moving dredge
Performance, and the continuity dredged is ensure that, improve ship dredging efficiency.The increase of DP3 dynamic positioning functions, make ship can be with
Adapt to more complicated severe sea situation.
Brief description of the drawings
The present invention is described in further details with reference to the accompanying drawings and detailed description.
Fig. 1 is the front view of the present invention；
Fig. 2 is the top view of the present invention.
In figure：1 main hull, 2 living areas, 3 reamer arm support structures, 4 reamer arms, 5 sideways-acting propellers, 6 full circle swingings promote
Device, 7 flexible propellers.
Embodiment
A kind of vertical lifting of all-around mobile reamer arm as shown in Figure 1-2 is from navigating cutter suction dredger, including the He of main hull 1
It is arranged on the living area 2 of main hull, the intermediate region of main hull 1 sets moon pool, reamer arm support structure 3 in moon pool, reamer arm
Reamer arm 4 movable up and down is set in supporting construction 3, and the bow of main hull 1 is provided with stem sideways-acting propeller 5, main hull 1
Stern be provided with ship stern all-direction propeller 6, the bottom of main hull 1 is provided with flexible propeller 7, and stretching propeller 7 can be with 360 °
Comprehensive revolution.It is vertical that the moon pool and reamer arm support structure 3 of the intermediate arrangement of main hull 1 can ensure that reamer arm 4 can be carried out
Motion, while dredging efficiency is ensured, shortens reamer arm configuration length, alleviates hull weight, be arranged in main hull bow
Stern and all kinds of propellers of bottom can not only make dredger carry out all-around mobile, ensure the continuity dredged.
In the present embodiment, living area 2 is arranged in the first half of main hull 1.Living area is arranged in main hull first half, so drives
