Abstract
The utility model relates to a kind of large crawl and grabs bucket than mechanical type six lobe, and bucket lobe is connected with strut bottom, and strut top realizes being rotationally connected by hinge and deck beam, and equalizing bar is arranged on deck beam, deck beam is provided with top sheave group; Top and the through beam of bucket lobe are hinged, through beam are provided with downslide wheels; Connected by steel rope between upper and lower assembly pulley; The corresponding strut of each bucket lobe is connected with deck beam, and each bucket lobe is connected with through beam.This grab bucket is applicable to port crane, and have larger crawl ratio, safety performance is good.Bucket lobe all adopts high-strength abrasion-proof board making, and strut part adopts high-strength structure board making, and pulley is that High molecular material makes, and reduces deadweight, improves and captures ratio.Arc vertical sectional shape in bucket lobe is approximate ellipsoidal, is flat bottom shape bottom C type gusset, and center of gravity reduces, safety and steady.Structure is simple, and reasonable in design, performance safety is reliable.
Description
Technical field
The utility model relates to a kind of grab bucket, relates in particular to a kind of mechanical type six lobe grab bucket of large crawl ratio, is mainly used in capturing block, powdery bulk material.
Background technology
The grab bucket of mechanical type six lobe uses comparatively general bulk handling instrument in port and pier, and it is made up of bucket lobe, deck beam, through beam, assembly pulley, strut, equalizing bar, guide rope device, steel rope, chain etc.The open and close of grab bucket is realized by pulley by steel rope.
Used six lobes grab buckets in harbour handling, with similar bivalve grab bucket by comparison, deadweight is comparatively large, generally captures than little from weighing about 3 tons, affect loading and unloading operation efficiency, also becomes harbour production problems faced.Existing orange-peel bucket, bottom arc is comparatively large, and center of gravity is higher, and less stable when placing at ordinary times, the phenomenon occurring wind or topple under the External Force Acting that other is less, exists potential safety hazard.
Therefore, providing the orange-peel bucket that a kind of structure is simple, reasonable in design, is the problem that these those skilled in the art need solve.
Utility model content
Technical problem to be solved in the utility model is, provide a kind of large crawl to grab bucket than mechanical type six lobe, it has crawl ratio
Larger, safety performance more failure-free feature.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme:
A kind of large crawl is grabbed bucket than mechanical type six lobe, and comprise equalizing bar, the below of described equalizing bar is provided with deck beam, and the below of deck beam is provided with through beam, deck beam is provided with top sheave group, through beam is provided with downslide wheels; On described deck beam, circumference has been evenly arranged six groups of upper ear seats, and on through beam, circumference has been evenly arranged six groups of lower ear bases; Also comprise the strut of six structural steel and iron forms, the upper end of strut is connected on upper ear seat correspondingly by hinge, and lower end connects the middle part of six bucket lobes correspondingly by hinge; The upper end of bucket lobe is connected on lower ear base correspondingly by hinge; It is characterized in that: the arc that described bucket lobe comprises wear-resisting steel plate material and the C type gusset of wear-resisting steel plate material be fixedly connected with arc.
Pulley in described top sheave group and downslide wheels is the pulley of macromolecule material.
The cross-sectional plane of described arc is approximate ellipsoidal.
Described C type gusset portion is flat bottom shape.
The beneficial effects of the utility model: the lobe that the first, struggles against all adopts high-strength abrasion-proof board making, strut part adopts high-strength structure board making, pulley is that High molecular material makes, when satisfied grab bucket intensity and rigidity, the more traditional orange-peel bucket of deadweight of this kind of grab bucket reduces by 3 tons, captures than increase 0.5.The second, approximate ellipsoidal bucket lobe (cross-sectional plane is for circular) compares with tradition bucket lobe (cross-sectional plane is equilateral polygon) when weight is identical, and area of contact is minimum, and volume is maximum, and center of gravity is low, and in operation process, grab bucket is not easy to topple over.Three, be flat bottom shape bottom the lobe C type that struggles against gusset, with contact area of ground greatly, stability is high, avoids to topple over phenomenon under non-operating condition, eliminates potential safety hazard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model; Fig. 2 is the front elevation of the utility model bucket lobe; The birds-eye view of Fig. 3 the utility model bucket lobe.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
As shown in Figure 1, a kind of large crawl is grabbed bucket than mechanical type six lobe, and this grab bucket comprises equalizing bar 1, and the below of described equalizing bar 1 is provided with deck beam 2, and be provided with hinge with on the bearing of deck beam 2 one, described hinge is through in equalizing bar 1.The below of deck beam 2 is provided with through beam 5.Deck beam 2 is provided with top sheave group 3, through beam 5 is provided with downslide wheels 6, be connected to each other by steel rope between top sheave group 3 and downslide wheels 6.
On described deck beam 2, circumference has been evenly arranged six groups of upper ear seats, and on through beam 5, circumference has been evenly arranged six groups of lower ear bases.
Also comprise six struts 4, the upper end of strut 4 is connected on upper ear seat correspondingly by hinge, and lower end connects the middle part of six bucket lobes 7 correspondingly by hinge.The upper end of bucket lobe 7 is connected on lower ear base correspondingly by hinge.
As shown in Figure 2,3, the C type gusset 9 that described bucket lobe 7 comprises arc 8 and is fixedly connected with arc 8.
Described bucket lobe 7 all adopts high-strength abrasion-proof steel plate to make.
Described strut 4 structure division all adopts high strength structure plate to make.
Pulley in described top sheave group 3, downslide wheels 6 all adopts High molecular material to make.
Described arc 8 adopts repeatedly flow forming and molding process, and centre needs to carry out stress relief annealing; Owing to creating plastic deformation, the rigidity of arc 8 is compared with the shaping increase of usual pressure.
Cross-sectional plane after described arc 8 is shaping is approximate ellipsoidal, and this shape face is amassed little, and volume is large, and material is very easy to be full of, and has extraordinary Grabbing properties; This structural focus is low, not easily topples in operation process.
Be flat bottom shape bottom described C type gusset 9, large with contact area of ground, stability is high, has stopped to topple over phenomenon under non-operating condition, eliminates potential safety hazard.
Above the utility model is described in detail.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification sheets; under the prerequisite not departing from the utility model spirit and scope, also have various changes and modifications, these changes and improvements all fall in claimed scope of the present utility model.Protection domain of the present utility model is defined by appending claims and coordinator thereof.
