Description
Technical field
The invention belongs to environmental dredging field more particularly to a kind of high-power tugboats to be raked device with heavy type.
Background technique
The prior art and defect:
It is harrowed from boat and inhales ship in dredging work, due to being influenced by factors, height always occurs in the seabed dredged
Uneven ridge and ditch, these ridges and ditch can be always with construction overall process, so that forming obstinate shallow area in blocks to the engineering later period
Or the shallow point in part.Using the drag head that rake inhales ship clear away these shallow areas and the production efficiency shallowly put it is very low under, it is time-consuming and laborious.Cause
This sweeps in shallow construction actual, the use of device of raking is very necessary.
Device of raking is saving cost, and it is quite apparent for shortening the construction period in effect.Rake device can with auxiliary ship station into
Row sweeps shallow leveling, therefore, sweeps and is shallowly not necessarily arranged in the engineering later period, may be implemented and harrows and inhale ship cooperation alternately construction, to save
The duration is saved, avoids sweeping shallow power dissipation and big ship holding time using rake suction ship.In addition, the acting surface for device of raking is wide, sweep shallow
Area is big, accurate positioning, construction flexibly, can large area sweep shallowly, can also for part shallowly put targetedly put down.
Existing device specification of raking is all less than normal, can be used only on middle-size and small-size tugboat, there is no the device of raking for large-scale tugboat, small
Type is raked, and device is of less demanding to the rigidity of structure, and structure is simple, and sweeping shallow efficiency will rake device well below large size.
Solve the difficulty and meaning of above-mentioned technical problem:
Therefore, these problems are based on, it is big to provide a kind of transverse width, increases work surface width, improves and sweep shallow efficiency；
By optimizing structural shape, the overall stiffness of heavy device of raking is improved, front end is avoided and blocks up that mud and spatula are passively sagging to ask
The heavy device of raking of the high-power tugboat of topic is with important realistic meaning.
Summary of the invention
It is big present invention aims at a kind of transverse width is provided to solve technical problem present in well-known technique, it increases
Work surface width, improves and sweeps shallow efficiency；By optimizing structural shape, the overall stiffness of heavy device of raking is improved, is avoided
Front end blocks up the high-power tugboat of the problem that mud and spatula passively sink and is raked device with heavy type.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that
A kind of high-power tugboat is raked device with heavy type, and the high-power tugboat is frame-type with the rake main structure of device of heavy type
Structure, the tower structure are separated into several cavitys by several midfeathers, and being equipped in each cavity has

Enter next course line set to continue to sweep shallowly.
As an example, in the present invention, the hoist cable on the side gallows of tugboat connects the lifting lug for device of raking by playing cat chain
On 10, hoist cable is driven by tugboat main winch.Traction rope via traction anchor chain connection rake device hawser hole 9 on, traction rope it is another
One end is connected on the bollard of tugboat front end.
In use, hoist cable on tugboat is transferred by the A type bracket device that will rake to dredging plane, tugboat is along pre-determined route
Navigation, traction rope drag device sweeping in dredging plane of raking and are higher by under traction power and the collective effect of front end bilayer cutter
The shallow point in dredging face can be scabbled, and deep point of backbreaking then is swept by the spatula of rear end.When completing after sweeping shallow of pre-determined route,
The hoist cable device that will rake lifts, tugboat u-turn, continues to sweep into next course line set shallow.
In conclusion increasing work surface width the present invention can provide a kind of transverse width is big, improves and sweep shallow efficiency；
By optimizing structural shape, the overall stiffness of heavy device of raking is improved, front end is avoided and blocks up that mud and spatula are passively sagging to ask
The high-power tugboat of topic is raked device with heavy type.
Above embodiments describe the invention in detail, but content is only the preferred embodiment of the present invention, no
It can be believed to be used to limit the scope of the invention.Any changes and modifications in accordance with the scope of the present application,
It should still fall within the scope of the patent of the present invention.
