Figure 13 surveys schematic diagram for the axle of this constant voltage control hitch device.
25 also are provided with hoisting mechanism 30 on the hull, partly mention with entry by 30 pairs of dredgings that are made of gravel pump, dredging head and pipeline of this hoisting mechanism and operate; Pylon 24, hoisting mechanism 30 and hoisting mechanism 27 can move front and back on the track of square body 25 axis, to satisfy the requirement of different operating modes; The operation (not shown) be holded up and be set level to pylon 24 can with oil cylinder.
During work, at first by handling hoisting mechanism 27, make 14 dives of vibrating type dredging head to appropriate depth, and locking hoisting mechanism 27, adjust the pulling force of oil cylinder 28, make the gravity of dredging part and the support force of water-bed bed mud and the pulling force of oil cylinder 28 reach balance, the motor 5 that starts on gravel pump 20, the dredging head by maneuver control device is worked then, carries out dredging operation.Wherein, dredging head 14 is by orbiting motion shown in Figure 10, the movement locus of dredging head 14 and rigid conduit 15 axis as shown in figure 11, the movement locus schematic diagram of any on the cutting cutterhead during then for vibration shown in Figure 12.
Water-bed bed mud is under the cutting of the vibration of dredging head 14 and dredging head end smear metal cutterhead, and partial liquefaction also forms the mud that has certain clod and sandstone, and soft bed mud can form under the influence of vibration and current and cave in around dredging head; The quarrel slurry that gravel pump 20 forms the dredging head end sucks and flows to its downstream gravel pump 26, and mud is finally drained into the stockyard by gravel pump 26, thereby realizes the dredging operation to the bottom.For more solid bed mud, in dredging head 14 work, by handling the swing mechanism on the hitch 23, make rigidity connecting rod 22 drive gravel pump 20 reciprocal rotary oscillations, and make reciprocal rotary oscillation around the vertical center line of gravel pump 20 by rigid conduit 18,15 drive dredging heads 14.After on the hitch 23 swing mechanism being set, can strengthen the dredging work area of dredging head 14, to improve the production efficiency of dredger, adapt to the bed mud dredging of different compactnesss.Because vibration is violent during dredging head 14 work, like this after between rigid conduit 18 and the rigid conduit 15 and between between rigid conduit 15 and the dredging head 14 flexible coupling being set, can effectively reduce vibration on the dredging head to the transmission of gravel pump, endanger to prevent that vibration from producing gravel pump 20, hitch 23 and hull 25, and energy-conservation.
After applying permanent pulling force upwards on the hitch 23, when hull 25 when fluctuate in the bottom relatively with water level fluctuation, oil cylinder 28 is flexible by its piston rod 28, can adjust in real time the position of hitch 23 relative pylons 24, thereby make dredging head 14 act on constant pressure on the bed mud, to guarantee dredging head 14 stable at water-bed dredging depth.When hull 25 rose, under dredging head 14 actions of gravity, oil cylinder piston bar 28 was protruding, reaches balance until dredging head gravity, bed mud support force, oil cylinder pulling force; When hull 25 descended, the pulling force that dredging head 14 acts on the wire rope 271 diminished, and oil cylinder piston bar 28 is regained, and reaches balance once more until dredging head gravity, bed mud support force, oil cylinder pulling force.
When the dredging part of being made up of gravel pump, dredging head and pipeline thereof need not worked under permanent state of tension, hitch 23 also can reached by hydraulic motor under the driving of the drive unit that is made of gear, tooth bar power train, along moving up and down of described vertical guide rail, wherein the gear in the drive unit, tooth bar power train are arranged between hitch 23 and the frame 24.
The swing mechanism of the setting on the above-mentioned hitch 23 also can be made of hydraulic motor, also can be made of with the drive unit that connecting rod that links to each other and fork constitute hydraulic motor or motor or oil cylinder.
According to the needs to different production capacity, input port, above-mentioned gravel pump 20 lower end place can be connected to, the rigid conduit section 18 of varying numbers such as five, seven.By middle one, the periphery is that square distributes when the quantity of rigid conduit section 18 is five; In the time of seven, be that regular hexagon distributes by one of centre, periphery.
