Induction installation 800 comprises: touch sensor 810, position sensor 820 and infrared acquisition machine 830, touch sensor 810 is located at rake teeth 200 and braces 100 junction, position sensor 820 is located at braces 100 and kuppe 400 junction, and the two ends of braces 100 are located at by infrared acquisition machine 830.
The rake teeth part of traditional trailing suction hopper dredger drag head adopts single flat pattern tooth head, flat pattern tooth head has the effect promoting and loosen the soil, but can reaction be started on the contrary for some natively very soft soils, caused the situation of digging, when excavating, angle is fixing simultaneously, cannot carry out adjusting can cause so leakage digging situation.Therefore, often after dredging, also need to carry out sweeping shallow follow-up work, spended time and cost, inefficiency.
The utility model improves in the structure of rake teeth and the mode of excavation.First, the utility model adopt the first rake teeth 230, second rake teeth 240 different with the 3rd rake teeth 250 3 kinds rake teeth to deal with different situations.And from more profound angle, be not only the rake teeth having prepared three kinds of different models, but the structure of these rake teeths is improved.
First rake teeth 230 comprises: blade type tooth head 231, girth member 232, first ratch 233, mud drainage slot 234 and reinforcing groove 235.Blade type tooth head 231 has the effect of cutting, can carry out ratio cutting by a large amount of mud of part, progressively clear up, prevent the situation of digging too.Mud can operationally be discharged by mud drainage slot 234, and preventing mud from lump on rake teeth affects follow-up result of use.Simultaneously in order to increase the firmness of rake teeth, adding and reinforcing groove 235, reinforcing groove 235 is the trench structures on the first ratch 233, and the inside arranges bar shaped girth member 232.In actual motion process, girth member 232 effectively can share pressure, and the life-span reducing rake teeth reduces, and reduces costs.
Second rake teeth 240 comprises: inverted T shape tooth head 241, second ratch 242 and lug boss 243.The effect that inverted T shape tooth head 241 is taken into account cutting simultaneously and loosened the soil, is applicable to the mud situation of more complicated.Simultaneously because the tooth head of T-shaped tooth head 241 is special, therefore reinforcing mode is limited, in order to wananty costs can not increase too high, the way increasing lug boss 243 at the peripheral edge portion of the second ratch 242 is have employed in the utility model, make the outer rim structure of the second ratch 242 as waveform, stressedly obtain dispersion, effectively add the intensity of the second ratch 242.
What the 3rd rake teeth 250 adopted is traditional flat pattern tooth head, and effect is loosening function.By driving wheel 210 and connector 220, make 3 kinds of tooth heads can carry out wheel disc conversion according to actual conditions, and how to judge adopting which kind of tooth head in what situations, the utility model adds multinomial watch-dog, is undertaken receiving and operating by PLC.
The utility model induction installation 800 comprises: touch sensor 810, position sensor 820 and infrared acquisition machine 830.Touch sensor 810 is located at rake teeth 200 and braces 100 junction, be whole machinery foremost, ensure that drag head is close to riverbed all the time, inhale to be in all the time and saturatedly dig real state, efficiency of construction obtains maximum performance.Avoid routine to dredge in the process of digging because riverbed is deep mixed, height is uneven, drag head jumps and forms the problem that " emptying " causes the pump suction inefficiency of construction.
Position sensor 820 is located at braces 100 and kuppe 400 junction, according to the pressure of current and the initial coordinate of initial setting value, the position of drag head and the situation of present position are monitored, guarantee is dug each time can in identical position, avoid the position at every turn dug not identical, cause riverbed rugged, need to carry out sweeping shallow.
The two ends of braces 100 are located at by infrared acquisition machine 830.Radar 700 is fixed on pony sill 300.The Main Function of infrared acquisition machine 830 coordinates radar to the position of dredge boat, and the situation in riverbed carries out seizure feedback.Infrared acquisition machine 830 principle is that both sides transmitting terminal launches infrared-ray to river bed simultaneously, river can not by radiation, just can be reflected back when infrared rays runs into mud, then just can by information feed back to PLC 900 by receiving terminal, make staff can obtain information accurately, conveniently carry out the adjustment of rake teeth angle.
Simultaneously in order to prevent the too small mud that causes of chain type grid 430 from block, or excessively cause excessive machine burden.We have devised butt hook 410 and chute 420 on kuppe 400, and butt hook 410 and chute 420 are slidably connected, and butt hook 410 are connected with chain type grid 430.Then by mobile butt hook 410 on chute 420, the effect of adjustment chain type grid 430 width can be reached by PLC 900.
Be illustrated detailed description of the invention of the present utility model above, but the utility model is not as limit, only otherwise depart from aim of the present utility model, the utility model can also have various change.
