Description
Technical field
The present invention relates to the special engineering equipment that the inland river desilting is dug sand, particularly a kind of well-type grab bucket is dug sand, dredger.
Background technology
The current domestic and international inland river desilting engineering of digging sand extensively adopts " chain-bucket dredge boat ", " pump suction type dredge boat " and " grab type dredge boat " etc. the major technique equipment.These equipments have been brought into play huge usefulness in actual applications, but the technical barrier that also all has limitation to some extent or be difficult to overcome.
1, " chain-bucket dredge boat " is the earliest and a large amount of special uses of using equipment of digging sand.This equipment is applicable to that phytal zone, loose shape granule silt adopts poly-operation.Simultaneously, although be to work continuously, rely on the mechanical energy work done when excavating because of it fully, so usefulness is not high, impact load is big during operation, and hull has obvious vibration, and overall efficiency is poor.
2, " strand suction formula dredge boat " is rivers desilting special purpose ship newly developed in recent years, and the distinguishing feature of this ship is to work continuously, and the usefulness height operates steadily, and also can use in the profundal zone.But, in actual applications, particularly when the operation of profundal zone, decrease in efficiency; Ancillary service is many; Choking phenomenon easily takes place; Oversize rock material and high N silt sand for alluvial are more powerless.
3, " grab type dredge boat " can solve the deficiency of above-mentioned two classes equipment preferably, begins to apply in recent years in industry is dug sand in the rivers desilting.Yet this equipment is limit because of himself structure and principle, and under the production capacity, efficient is not high, and stability of hull is poor, and it is big to shake the width of cloth in length and breadth, unsuitable operation under bad weather.At present, domestic and international similar ship type, two 3000 tons of ships of disposable maximum load can be grabbed and be carried 18 tons/time.
Summary of the invention
The objective of the invention is in order to overcome the defective in the above-mentioned technology, provide that a kind of system architecture advanced person, production capacity well-type grab bucket big, that operate steadily is dug sand, dredger.
Described a kind of well-type grab bucket is dug sand, dredger, comprise hull, power switch room, power and auxiliary storehouse, anchor chain stable car, it is characterized in that: the penetration type vertical shaft is set, built on stilts steel fine strain of millet vertically is set at hull at midship, on built on stilts steel fine strain of millet, rail and pinwheel track are set, dolly hoists, the dolly that hoists is provided with crane parts and grab bucket, and the described dolly that hoists is rotationally connected by rail and pinwheel track and built on stilts girder steel, and the crane parts on the dolly that hoists is connected with grab bucket by wirerope.

Also be provided with pug conveyer belt 23 on hull penetration type vertical shaft 22 limits.In power and the auxiliary storehouse 17 gen-set is set.Central control room 8 for well-type grab bucket is dug sand, between the controlling of dredger normal operation, the electric major loop of the variable-frequency governor of hoisting mechanism, each equipment is concentrated and is arranged in the power switch room 12.
Well-type grab bucket is dug sand, the explanation of dredger workflow:
1, channel cleanout operating mode: the hull anchor lain in needs cleaning place upstream, and according to status of the water area anchor being set is wirerope length, and sludge boat is moored in main ship one side, start main frame, lifting dig sand dolly, adjust belt conveyor and can start working.Dispensing grab bucket, pick up pug, travelling car unloads silt in the silt particle hopper, by conveyor mud is delivered on the sludge boat.Look the excavation situation and adjust the dolly position, under not mobile hull situation, generally excavation scope should be 6 meters * 6 meters.After this place cleaned out, dispensing anchor heaving pile (once dispensing is about 6 meters) moved hull by current, and change place continues to excavate.Slow as water velocity, also can be in mining process slow mobile hull.
2, the operating mode of digging sand: need sand carrier, fortune mudstone ship and ore carrier retinue work when digging sand operating mode.The hull anchor is lain in the upstream, operation area, adjust anchor and be wirerope to appropriate length, mudstone ship and sand carrier are moored in the workboat both sides, and the ore carrier mooring is in the workboat rear portion.Start main frame, lifting dig sand dolly, adjust each conveyer and cargo ship relative position to suitable, can discharge grabs bucket starts working.Dispensing grab bucket, pick up pug, travelling car unloads the sandstone material of picking up to the middle part feed bin, behind sand washing machine washing brush, deliver to hopper, enter sand-stone separator and separate the mudstone after the separation by the both sides bucket conveyor, by gathering-device, belt conveyor, deliver to the mudstone ship; Granule after the separation enters the ore separators screening, and selected ore in sand form is delivered on the ore carrier by afterbody through collection storage device, belt conveyer; The washed ore of screening is delivered on the sand carrier by chain bucket, belt conveyor.
Embodiment: the equipment that the present invention is trial-produceed successfully is installed on 900 tons the depressed place ship, in inner lead (flow velocity is less than 1m/s) actual measurement production capacity: 35 meters of depth of implements, single grab carrying capacity 40 ~ 45 tons/time, per hour grab and carry about 40 times, silt particle and grab about 1000 tons/hour of carrying capacity only.Maximum lift speed 45m/min, maximum lowering velocity 65m/min, machine system is equipped with power 800Kw.Hull is steady during work, and no impact load shakes not obviously in length and breadth, and the busy hour hull sinks only 5 centimetres, and silt particle is grabbed carrying capacity only and can be comprised for 1000 tons/hour: about 250 tons/hour of mudstone amount, about 70 tons/hour of the husky amount of sand, about 600 tons/hour of smart husky amount.With respect to existing similar equipment, has tangible technological precedence advantage.
