Description
Technical field
The present invention relates to the dredging works equipment and technology, particularly a kind of cutter suction dredger adjustable reamer dredger.
Background technology
Because of natural or artificial reason, at the many mud of the bottom deposit in rivers, lake and coastal waters.For purify water, renovating environment and dredging channel, people adopt dredging vessel to clear up mud usually.At present, the kind of dredging vessel is a lot, and the cutter suction dredger that is made of reamer and slush pump is widely used.This dredge boat is to rely on reamer self rotation be located at reamer crane span structure front end, swing and dredge pump suction carrying out work, with the earth of designated depth under water loose and by suction to specifying the dumping area.Traditional cutter suction dredger causes dredging water pollution and work plane to be uneven because technology is relatively backward through regular meeting.In recent years, the parties concerned have done unremitting effort in order to improve its deficiency, are 92219536.6 to disclose a kind of " crown formula reamer cover " as the patent No..Crown formula reamer cover is made of end device water baffle cover on reamer back side device water baffle, the reamer.The water baffle cover is connected in back side water baffle by bearing pin, and leading edge adopts circular arc.This reamer cover can not be opened, the obstruction difficulty on cleaning reamer top.The reamer cover is an open architecture, and suction mud concentration is lower; The patent No. is 00264795.8 disclose a kind of " novel environment friendly dredging reamer ", and this reamer is made up of cutter tooth, reamer ringlet, propeller boss, reamer great circle, uses the welding manner moulding between the each several part, and its cutting edge is distributed on the same taper seat.Though this reamer section that digs when certain depth is a plane, when rising and falling the crane span structure change in depth, wave-like can appear in its section that digs, excavate precision and degenerate, and can not excavate hard soils.
Summary of the invention
The objective of the invention is to propose a kind of new dredger at the existing problem of above-mentioned existing dredging technology, this device can not only satisfy the requirement of environmental dredging, and the reamer plugging fault is few, and it is convenient to get rid of, the production efficiency height, applied widely to soil property, desilting quality height.
To achieve these goals, the present invention proposes a kind of cutter suction dredger adjustable reamer dredger.This device by reamer levelling device, protective cover headstock gear, cut the defeated mud device of mud, fluid pressure drive device is formed.
The reamer levelling device is made of bracket component, hydraulic jack, cutter holder assembly, pivot pin.Bracket component and cutter holder assembly connect and compose leverage by pivot pin and hydraulic jack.Under the hydraulic jack effect, cutter holder assembly can rotate around pivot pin, realizes that reamer is at different depth, the different domatic mud that excavates effectively down.
The protective cover headstock gear is made of hydraulic jack, hinge, pivot pin, protective acoustic cover assembly.Protective acoustic cover assembly links to each other with hydraulic jack by pivot pin, oil cylinder, hinge and pivot pin constitute the hinge leverage, effect low protection cover assembly at hydraulic jack can realize that protective cover opens and closes function, is convenient to clear up the obstruction of reamer inner chamber around the hinge through of its end.
Cutting the defeated mud device of mud is made of reamer assembly, dredging tube, protective acoustic cover assembly.The reamer assembly comprises tool arm, spiral slurry conveying machine structure, propeller boss and cutter ring.Tool arm is the spatially spiral structure, and two ends are separately fixed on propeller boss and the cutter ring, and the tool arm cutting edge all is distributed on the same taper seat.Spiral slurry conveying machine structure is installed in the chamber of reamer, is fixedly linked with tool arm, propeller boss.The loose earth of reamer rotation is delivered to the dredging tube mouth by spiral slurry conveying machine structure with it, is siphoned away by dredging tube.
Fluid pressure drive device is made of hydraulic motor, mangler shaft, rolling bearing, underwater sealing assembly, and under the effect of hydraulic pressure energy, hydraulic motor rotates, and drives the mangler shaft rotation;
The present invention has the following advantages:
(1) owing to can adjust attitude at any time, thereby can guarantee that different depth, different cutting edge and bottom mud in lake under domatic develop, effectively remove mud, bottom surface, lake landform is had excellent adaptability at dredging process reamer assembly;
(2) owing to adopted more excellent reamer modular construction, thus stronger to excavating soil property compliance;
(3) owing to have the protective cover headstock gear, in the dredging process, in case stopping up, reamer needs the cleaning obstruction, can pass through hydraulic jack, open the protective acoustic cover assembly of reamer assembly top rapidly, in time remove the obstruction on the reamer, shortened the shut-down clearance time, increase the effective working time, thereby improved operating efficiency;
(4) reamer assembly top is provided with protective acoustic cover assembly, and protective cover is long taper semi-closed state, can stop the mud water body diffusion outside cover in the reamer chamber effectively, prevents secondary pollution; Simultaneously, in suction mud process, stop the outer water body of cover in cover, to replenish, improved the concentration of suction mud, high efficiency;
(5) this device adopts the modular structure design, can exchange with dredge boat standard reamer head and use.That is: when common dredge boat needs environmental dredging, only need to change primary standard reamer head, remake control adjustment then, promptly become an environment-friendly type dredge boat, thereby can shorten the technological transformation cycle, reduce manufacturing cost with this device.
(6) this apparatus structure is simply compact, and flexible and convenient operation is safe and reliable.
