Embodiment
Reference picture 1, Fig. 2, the present invention are a kind of cutter suction dredger with reamer support lift device, including the He of hull 1
Reamer support 5, hull 1 include deck 11 and bottom plate 12, and the stem of reamer support 5 is installed with reamer first 6, in addition to reamer branch
The lifting device 2 of frame, the bottom of lifting device 2 are fixedly connected with bottom plate 12, and the top of lifting device 2 rotates with the afterbody of reamer support 5
Connect, the retractor device 21 that can lift the afterbody of reamer support 5, the stem of reamer support 5 are provided between the top and bottom of lifting device 2
Outstanding to lie in the one end of a steel wire rope 3, the other end of steel wire rope 3 is connected with winch 4.
Winch 4 drives steel wire rope 3, and the stem that steel wire rope 3 draws reamer support 5 rotates around its afterbody, in certain operating angle
Vertical circular motion is carried out in the range of degree.When cutter suction dredger is in normal/cruise or non-mud prune job, at reamer support 5
In S1 positions, higher than the water surface；When reamer support 5 is in S2 positions, reamer first 6 is in most shallow cut mud depth, most shallow cut mud depth
For h1；When reamer support 5 is in S3 positions, reamer first 6 is dredged depth in maximum, and maximum depth of dredging is h2, then twists to inhale and dig
The mud cleaning effective operation depth of mud ship is h2-h1.When reamer support 5 is in S2 positions, when the retractor device of lifting device 2
21 elongations upwards, the afterbody of reamer support 5 is lifted certain height and reaches S4 positions, makes reamer first 6 concordant with the water surface, most
Shallow cut mud depth is improved to the water surface, you can mud more than cleaning h1 depth.Pass through retractor device 21 and winch 4 and steel wire rope 3
The height of the afterbody of reamer support 5 and stem is controlled respectively, so as to expand the vertical job area of cutter suction dredger.
As the preferred embodiment of the present invention, retractor device 21 includes cylinder body 211 and may compress into flexible in cylinder body 211
Bar 212, cylinder body 211 are embedded in hull 1, and the bottom of cylinder body 211 by installing plate and sets mounting hole on a mounting board and bottom
Plate 12 is fixedly connected, and the top of cylinder body 211 is concordant with deck 11, and the length of expansion link 212 is less than the length of cylinder body 211.
As the preferred embodiment of the present invention, retractor device 2 is hydraulic jack, and cylinder body 211 is cylinder body of hydraulic oil cylinder, is stretched
Contracting bar 212 is hydraulic cylinder piston rod.
As the preferred embodiment of the present invention, the top of lifting device 2 is provided with supporting plate 22, and supporting plate 22 is provided with support
Seat 221, support base 221 are provided with the mounting hole 222 with the rotation connection of the afterbody of reamer support 5.Reamer support 5 and mounting hole 222
Connected by a rotating shaft.
When reamer support 5 works between S2 positions and S3 positions, retractor device 21 is not at working condition and not lifted
The afterbody of reamer support 5, because the length of expansion link 212 is less than the length of cylinder body 211, expansion link 212 can be reduced to cylinder body completely
In 211, and the top of cylinder body 211 is concordant with deck 11, and supporting plate 22 is fallen on deck 11, is supported by deck 11, as shown in figure 3,
Now expansion link 212 does not provide support force to supporting plate 22, it is ensured that stability of the reamer support 5 when higher depth works.
As the preferred embodiment of the present invention, lifting device 2 also includes guide rod 25, and guide rod 25 and expansion link 21 are flat
Row is simultaneously fixedly connected with bottom plate 12 and deck 11, and the top of guide rod 25 passes through supporting plate 22, and supporting plate 22 is slided on guide rod 25
It is dynamic.
Guide rod 25 ensures that supporting plate 22 and reamer support 5 move up and down in vertical direction, prevents reamer support 5 from offseting
It is unstable.Connected between supporting plate 22 and guide rod 25 using cod, reduce sliding-frictional resistance.
As the preferred embodiment of the present invention, the quantity of guide rod 25 is two, and is symmetrically arranged in 23 liang of support base
Side.
As the preferred embodiment of the present invention, the quantity of retractor device 21 is two, and is symmetrically arranged in support base 23
Both sides.
The quantity of guide rod 25 and retractor device 21 is two and is arranged symmetrically, and ensure that whole lifting device 2 is being lifted
With stability during bloster hinge knife support 5.
As the preferred embodiment of the present invention, the stroke of the detection collapsing length of retractor device 21 is additionally provided with supporting plate 22
Sensor 223.
As the preferred embodiment of the present invention, retaining mechanism is provided between supporting plate 22 and hull 1.Retaining mechanism is being stretched
Compression apparatus 21 is locked at supporting plate 22 on hull 1 when not lifting reamer 5 afterbody of support, prevents supporting plate 22 in reamer support 5
Produce vibration at work with reamer first 6.
The operating procedure now to the present invention with the cutter suction dredger of reamer support lift device is described as follows：
A. the retaining mechanism between hull 1 and supporting plate 22) is released, supporting plate 22 is in movable state；
B.) under the effect of outside hydraulic control system, high pressure liquid force feed is synchronously flowed into two cylinder body of hydraulic oil cylinder 211
It is interior, make the synchronous motion upwards of two hydraulic cylinder piston rods 212, promote the afterbody of reamer support 5 to move upwards；
C. when the stroke sensor 223) being installed in supporting plate 22 produces signal, supporting plate 22 rises to correct position,
Fuel cut-off, hydraulic cylinder piston rod 212 stop moving upwards；
D.) winch 4 discharges steel wire rope, the stem of reamer support 5 is moved downwardly to the water surface under outside control action, this
When reamer support 5 and the water surface angle in the angular range of reamer normal work, cutter suction dredger carries out mud prune job,
Now to being cleared up away from the mud in the range of water surface depth h1；
E. after) cutter suction dredger cleans out to depth h1 mud, under the effect of outside hydraulic control system, hydraulic oil
Flow out cylinder body of hydraulic oil cylinder 211；Supporting plate 22 moves downward touch hull 1 after, hull 1 be reamer support 5 provide support force,
Hydraulic cylinder piston rod 212 no longer provides support force for reamer support 5；
F. retaining mechanism is in locking state, prevent supporting plate 22 from being slided relative to hull.Cutter suction dredger starts pair
The mud of depth carries out prune job most between shallow cut depth and maximum dredging depth.
Certainly, the invention is not limited to above-mentioned embodiment, and those skilled in the art are without prejudice to originally
Equivalent variations or replacement can be also made on the premise of spirit, these equivalent modifications or replacement are all contained in the application right
It is required that in limited range.
