The technical scheme that provides according to the utility model; Three or the four multiplying power operation current mechanisms of grabbing bucket mainly comprise deck beam, through beam, strut, bucket body, switching rope, guide wheel, top sheave group and downslide wheels; Said deck beam and strut upper end are articulated and connected, and strut lower end and bucket body side are articulated and connected.Said bucket body upper end is articulated and connected with through beam.
Be provided with the top sheave group in the said deck beam, comprise the top sheave that two left-right symmetric distribute in the top sheave group, two top sheaves are set on the upper pin.Be provided with the downslide wheels in the said through beam, comprise the lower sheave that four left-right symmetric distribute in the downslide wheels, four lower sheaves are set on the lower bearing pin.Said deck beam upper end connects guide wheel.
In deck beam, be provided with the deck beam cover of wedge, be provided with the through beam cover of wedge in the through beam.
Connect the up-down rope on the said deck beam, connect the switching rope on the guide wheel of deck beam.
Three multiplying power operation windings of grab bucket are to open and close rope to get into a lower sheave in the downslide wheels through guide wheel, and then get into top sheave, are connected at last on the through beam cover of wedge.Four multiplying power operation windings of grab bucket are to open and close rope to get into a lower sheave in the downslide wheels through guide wheel, and then get into another lower sheave in the downslide wheels through top sheave, are connected at last on the deck beam cover of wedge.
Compared with present technology the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Can when grasping different material, obtain grip preferably, can improve the work efficiency of grab bucket again, satisfy three or four multiplying power job requirements simultaneously; Easy to operate, reduced the cost of equipment.

The specific embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
Shown in Fig. 1 ~ 2; The utility model mainly comprises deck beam 1, through beam 2, strut 3, bucket body 4, opens and closes rope 6, guide wheel 7, top sheave group 8 and downslide wheels 9; Said deck beam 1 is articulated and connected with strut 3 upper ends, and strut 3 lower ends and bucket body 4 sides are articulated and connected.Said bucket body 4 upper ends and through beam 2 are articulated and connected.
Be provided with top sheave group 8 in the said deck beam 1, comprise in the top sheave group 8 that 14, two top sheaves 14 of top sheave that two left-right symmetric distribute are set on the upper pin 12.Be provided with downslide wheels 9 in the said through beam 2, comprise in the downslide wheels 9 that 15, four lower sheaves 15 of lower sheave that four left-right symmetric distribute are set on the lower bearing pin 13.Said deck beam 1 upper end connects guide wheel 7.
Shown in Fig. 3 ~ 4, in deck beam 1, be provided with deck beam cover of wedge 10, be provided with through beam cover of wedge 11 in the through beam 2.
Connect up-down rope 5 on the said deck beam 1, connect switching rope 6 on the guide wheel 7 of deck beam 1.
Shown in Fig. 5 ~ 6, three multiplying power operation windings of grab bucket are to open and close the lower sheave 15 that rope 6 gets in the downslide wheels 9 through guide wheel 7, and then get into top sheave 14, are connected at last on the through beam cover of wedge 11.Four multiplying power operation windings of grab bucket are to open and close the lower sheave 15 that rope 6 gets in the downslide wheels 9 through guide wheel 7, and then through another lower sheave 15 that top sheave 14 gets in the downslide wheels 9, are connected at last on the deck beam cover of wedge 10.
The principle of work of the utility model is: in use, if the material ratio that grasps is easier to grasp, need the grab bucket efficiency operation, then take three multiplying power operation windings.Every opens and closes the lower sheave 15 that rope 6 gets in the downslide wheels 9 through guide wheel 7, and then gets into top sheave 14, is connected at last on the through beam cover of wedge 11, and two other lower sheave 15 in the downslide wheels 9 is inoperative.Grab bucket just can realize the high-efficiency homework of three multiplying powers when operation.If during the difficult extracting of the material that grasps, just need take four multiplying power operation windings.Every opens and closes the lower sheave 15 that rope 6 gets in the downslide wheels 9 through guide wheel 7, and then through another top sheave 14 that top sheave 14 gets in the downslide wheels 9, is connected at last on the deck beam cover of wedge 10.After taking four multiplying power operation windings, the closing force of grab bucket is enough, and closing period is also longer, and grip is better.
In same grab bucket, realize three or four multiplying power operations, can when grasping different material, obtain grip preferably, can improve the work efficiency of grab bucket again, easy to operate, reduced the cost of equipment.
