The twin-bucket wheel type under water operating principle of mud-suction dredging machine step device is: ship is moved to desilting place, utilize pile frame 32 that guide pile 31 is holded up, unclamp steel cable, guide pile 31 inserts in water-bed mud along the anchor ear 38 falling on pile frame 32 because of self gravitation, and recycling is fallen the latch 36 of pile frame 32 left and right sides and will be fallen pile frame 22 and be fixed on hull 1.In like manner water is put into in other two groups of guide pile unit, form three location.

The loosening steel cable of hoist engine 66 in the middle of starting, the row frame 69 that is connected in hull head by cross connecting piece 65 extend into the bottom under Gravitative Loads, start desilting equipment, drive twin-bucket wheel type desilting 3 to carry out desilting, under the effect of entering the sludge pump that mud Guan Qi connects in two bucket wheels of described twin-bucket wheel type desilting 3, will in the mud suction pipe of cleaning, through sludge pump and mud pipe, be discharged to assigned address.When needs carry out hull 1 left direction desilting, start left hoist engine 62, left hoist engine 62 tightens up steel cable with certain speed, and steel cable pulls row frame 69 to move to the left by the horizontal stake 61 in a left side, and right hoist engine 67 unclasps steel cable with identical speed simultaneously; When needs carry out hull 1 right direction desilting, start right hoist engine 67, right hoist engine 67 tightens up steel cable with certain speed, and steel cable pulls row frame 69 to move to the right by the horizontal stake 68 in the right side, and left hoist engine 62 unclasps steel cable with identical speed simultaneously; In the middle of starting after desilting completes, hoist engine 66 is mentioned row frame 69.

The hoist engine 34 that starts hull 1 two guide pile unit of head, tightens up steel cable, and steel cable pulls reference column 31 to move upward along two anchor ears 38 that fall on pile frame 32 by pulley 33, until travel switch 37 shake-up on guide pile, hoist engine 34 machine stop motions; Extract down the latch 36 of pile frame 32 both sides, the pile frame that will fall rotates rearward to fall down along rotational support body 35, and by the guide pile horizontal positioned of falling on pile frame 32, to hull 1, now hull 1 only has guide pile cell location of afterbody.

Start step device, the trolley body 53 of step device is positioned at the original position of the head of trolley body rail bracket 51, the guide pile 52 of hull 1 afterbody guide pile unit is positioned in water, start the second hoist engine 59, steel cable is led and is pulled back trolley body 53 and move to hull afterbody through pulley 58, because trolley body 53 is fixed on riverbed through guide pile 52, the track 56 of trolley track frame 51 and the relative displacement of the wheel of trolley body 53 55 generations to hull cephalad direction, trolley track frame 51 with hull 1 for being fixedly connected with, drive hull 1 to move forward, when the position switch 57 of the afterbody on trolley track frame 51 touches trolley body 53, hoist engine stops operating, hull completes reach.

Two groups of guide pile unit of hull 1 head are positioned in water again, one group of guide pile unit of hull 1 afterbody is mentioned, the first hoist engine 54 on firing platform car body 53, hoist engine tightens up steel cable, and steel cable is connected in hull, pull trolley body 53 to moving to hull 1 head position with respect to hull 1, until touch position switch 57, the first hoist engines 54 of trolley track frame 51 heads, stop operating, trolley body 53 is got back to initial position, put down the guide pile unit of hull 1 afterbody, complete three location.

The loosening steel cable of hoist engine 66 in the middle of again starting, puts into the bottom by the twin-bucket wheel type desilting of row frame 69 heads 3, carries out horizontal desilting, spoil disposal.

Repeat above-mentioned steps, until desilting completes.
