Be connected on the side pawl, second body of rod is hinged on second sliding block, second body of rod and first sliding block it
Between be equipped with second connecting rod, second sliding block relative to first sliding block move when, pass through the second connecting rod and drive the side
Pawl is rotated relative to the pawl arm in the pawl arm rotation direction.
When pawl arm opens release rubbish, rubbish easily is clamped since side pawl collapses, rubbish, which is remained on pawl arm, to be influenced just
Often release, therefore by setting split type sliding block, the first sliding block and the second sliding block produce opposite move when moving up sliding block
It is dynamic, so as to pull side pawl to rotate by second connecting rod, side pawl is staggered with pawl arm, avoid clamping rubbish between the two.
Preferably, the pawl arm is equipped with rotation seat, the rotation seat is rotatably installed on the pawl arm, the side pawl
Rotate on the rotation seat, the pivot center pawl arm opposite with the rotation seat of the relatively described rotation seat of side pawl
Pivot center is vertical, the relatively described rotation seat of the side pawl is driven the side to the pawl arm lateral rotation, the rotation seat
Pawl is rotated relative to the pawl arm to the pawl arm rotation direction.
Preferably, the bearing includes first support and second support, the first support and the second support are in
It is horizontally disposed up and down, and the relatively described first support of the second support moves left and right, the movable pulley is installed on described first
On stent, the pawl arm is installed in the second support.
Preferably, second support is connected between the first support and the 3rd stent, the second support
Upper end is hinged in the first support, its lower end is hinged on the 3rd stent, the first support, the second support
Parallelogram sturcutre is formed with the 3rd stent.
Beneficial effects of the present invention：The present invention opens side pawl when capturing rubbish, increases pawl by the side pawl of setting activity
The crawl area of arm, improves grab bucket crawl amount；Side pawl is collapsed when discharging rubbish, realizes quick release rubbish, and will not incite somebody to action
Rubbish is remained on pawl arm；And fixed pulley mechanism is employed between grab bucket and lifting reel, the moiety by weight of grab bucket is disperseed
In moving cart, steel wire rope is born the weight of bigger, increase the cargo dead-weight of crane, reduce the work of lifting reel
The rate of doing work, improves rubbish cleaning efficiency.
