The operating principle of the present utility model and the course of work are as follows: in the time will removing contamination to the dirt in the grid, the utility model is pressed following order work:

(1) location.After starting this machine, the motor reduction gearing mechanism 25 in the walking mechanism drives driving shaft 26 ground-engaging wheels 27, and road wheel 27 drives the utility model and walks on guide rail 10, and it is moved to the job position that need drag for clearly, realizes the location.

(2) drag for work cycle clearly.When dragging for clearly, motor in the mechanism of the starting elevation angle, screw mandrel 171 forwards (or oppositely) that drive in the motor reduction gearing mechanism 18 driving leading screw and nut mechanisms 17 rotate, thereby drive the connecting rod rising (or decline) on the nut 16 and drive crank 15 risings (or decline), thereby make revoliving arm 28 (or the downwards) angle of swing upwards in the double telescopic mechanism 2, drive two telescopic arms 11 and on tipping bucket 5 outwards show (or inwardly pendulum advance), to adjust telescopic arm 11 and to treat to drag for clearly relative position between the grid of dirt, mutually in good time until both, close the motor in the mechanism of the elevation angle, with this relative position locking.Start hoist engine in the hoisting mechanism 4 this moment, loosens wire rope 13, then two telescopic arms 11 in multistage connecting rod and tipping bucket 5 descending by conducting oneself with dignity, until when needs drag for the position clearly, close hoist engine, locking steel wire rope 13.Start motor in the mechanism of the elevation angle this moment, and elevation angle mechanism is resetted, angle of tipping bucket 5 turning anticlockwises then, and in its turning course, the anterior rake teeth of tipping bucket is fitted with the grizzly bar of grid, and dirt is placed in the tipping bucket, and realization is dragged for clearly.Start hoist engine this moment, reclaim wire rope 13, then multistage connecting rod and the tipping bucket 5 in two telescopic arms 11 is up by rope traction, multistage connecting rod is shunk in telescopic arm 11 by the effect of steel cable pulling force, the dihedral fork 21 that drives in the tipping bucket is up, when multistage connecting rod goes upward to second side rod of dihedral fork 21 and push rod on the telescopic arm 11 contacts, dihedral fork 21 begins action, pin joint revolution around its bight 33, first side rod begins 24 application of forces of the internal conflict in the tipping bucket 5, with its extrapolation, because this moment, multistage connecting rod continued to shrink in telescopic arm 11, this first side rod will continue 24 application of forces of the internal conflict in the tipping bucket 5, with its continuous extrapolation, in telescopic arm 11, to shrink when putting in place until multistage connecting rod, the internal conflict 24 in the tipping bucket 5 has been turned round an enough big angle (referring to Fig. 5) around strand 32, the dirt of conflicting internally this moment in 24 is toppled over out owing to be subjected to the effect of gravity, pours in the dirt car 9.But stay cord 21 was had an effect to hold and was conflicted internally 24 this moment, made its not overturning downwards.Because multistage connecting rod shrinks when putting in place in telescopic arm 11, spring 20 is subjected to the second side rod gyroscopic action of dihedral fork and tension, after the dirt in the internal conflict 24 is poured out, start hoist engine this moment, loosen steel cable 13, multistage connecting rod is subjected to the deadweight effect descending, dihedral fork 21 has the trend that is separated with push rod 19, but is subjected to the effect of spring 20, and dihedral fork 21 also keeps contacting with push rod, produce clockwise backswing action simultaneously, when being returned to Fig. 4 position, because the pulling function that produced with dihedral fork 21 returns by stay cord 22, internal conflict 24 is pulled, when its center of gravity surmounts hingedly 32 the time left, conflicting internally 24 will reset under its deadweight effect.So just finished the process of removing contamination, below removed contamination the repetition said process.

The utility model is provided with anti-dumping mechanism, when it mentions dirt when overweight, machine gravity has bigger displacement, for preventing to tumble, being fixed on the inboard projection that is provided with in lower end of the support 35 on the frame 7 or the gap 37 between the I-shaped guide rail 10 under roller 36 and the road wheel will reduce, make this projection or roller hook the upper limb of guide rail 10, thereby complete machine is fastened on the guide rail 10 unlikely tumbling.

The utility model to grid before the dirt at different depth of waters place drag for clearly, only need control that the overhang of level connecting rod gets final product more than the telescopic arm bottom.The progression of multistage connecting rod depends on the installation site at the remove contamination on-the-spot depth of water and this machine and the scene of removing contamination, and suitably chooses its parameter, also can realize dragging for clearly the dirt of pressing close to the bottom.And it does not have specific (special) requirements to operation field, is suitable in adverse circumstances, seriously piling up under the situation of dirt using.
