Abstract
A totally enclosed grab bucket. At present, the upper parts of double jaw bucket bodies of bridge type grab ship unloaders are both open, and coal scattering and dust raising phenomena are easy to occur in the process of unloading for non-closed transportation. The utility model discloses the constitution includes: double jaw lamella bucket body (8) that constitute by two symmetrical bucket lamella (12) on left and right sides, the bucket lamella adjacent one side be connected through middle round pin axle (9) with bolster (10) down, the opposite side of bucket lamella be connected through vaulting pole round pin axle (7) with the lower extreme of vaulting pole (4), the upper end and the last bolster (2) of vaulting pole articulated, the front and back side of bucket lamella upper end on weld respectively trapezoidal curb plate (6), two trapezoidal curb plate between the welding have apron (5). The utility model is used for totally enclosed grab bucket.
Description
The technical field is as follows:
the utility model relates to a totally enclosed grab bucket.
Background art:
at present, the upper parts of double jaw bucket bodies of bridge type grab ship unloaders are both open, and coal scattering and dust raising phenomena are easy to occur in the process of unloading for non-closed transportation.
The utility model has the following contents:
the utility model aims at solving current bridge type grab bucket ship unloader's double jaw lamella bucket body upper portion all is the open-type, easily appears spilling the problem of coal, raise dust at the in-process of unloading, provides one kind and has effectively reduced bridge type grab bucket ship unloader spill coal, raise dust phenomenon at the in-process of unloading, the totally enclosed grab bucket that the feature of environmental protection is good.
The above purpose is realized by the following technical scheme:
the utility model provides a totally enclosed grab bucket, this kind of totally enclosed grab bucket includes the double jaw lamella bucket body that two left and right symmetrical fill lamellas constitute, the adjacent one side of fill lamella and bolster pass through middle round pin hub connection down, the opposite side of fill lamella pass through the strut pin hub connection with the lower extreme of strut, the upper end and the last bolster of strut articulated, the front and back side of fill lamella upper end on weld trapezoidal curb plate respectively, two trapezoidal curb plate between the welding have the apron.
The fully-closed grab bucket is characterized in that an upper pulley of the upper bearer is connected with a lower pulley of the lower bearer through a steel wire rope.
Has the advantages that:
1. the utility model discloses a both sides all weld trapezoidal curb plate around the upper end of bucket lamella, and trapezoidal curb plate welding is between vaulting pole round pin axle and middle round pin axle, and the welded cover plate forms totally enclosed double jaw lamella bucket body between two trapezoidal curb plates, has effectively reduced the coal, the raise dust phenomenon of spilling of bridge type grab ship unloader at the in-process of unloading, and the feature of environmental protection is good.
The utility model discloses set up the structure of trapezoidal curb plate, can effectively enlarge the volume of grab bucket, prevent that the phenomenon of transshipping from appearing in the closed in-process of grab bucket.
Description of the drawings:
FIG. 1 is a front view of the present invention;
fig. 2 is a side view of the present invention;
in the figure: 1. a hoisting chain; 2. an upper bolster; 3. an upper pulley; 4. a stay bar; 5. a cover plate; 6. a trapezoidal side plate; 7. a stay pin shaft; 8. a double jaw bucket body; 9. a middle pin shaft; 10. a lower bolster; 11. a lower pulley; 12. a bucket petal.
The specific implementation mode is as follows:
example 1:
the utility model provides a totally enclosed grab bucket, this kind of totally enclosed grab bucket includes the double jaw lamella bucket body 8 that two left and right symmetrical fill lamella 12 constitute, the lock is in the same place in the middle of two fill lamellas, the adjacent one side of fill lamella be connected through middle round pin axle 9 with lower bolster 10, the opposite side of fill lamella pass through vaulting pole round pin axle 7 with the lower extreme of vaulting pole 4 and be connected, the upper end of vaulting pole articulated with upper bolster 2, the front and back side of fill lamella upper end on weld trapezoidal curb plate 6 respectively, two trapezoidal curb plate between the welding have apron 5.
Example 2:
according to the totally enclosed grab bucket of embodiment 1, the upper pulley 3 of the upper bolster is connected with the lower pulley 11 of the lower bolster through a steel wire rope.
The bridge type grab ship unloader lifts the whole device through the hoisting chain 1 during hoisting, the upper pulley is connected with the lower pulley through a steel wire rope, power equipment is arranged on the upper pulley, the upper pulley is controlled by the power equipment to rotate so as to realize that the steel wire rope is wound on the upper pulley and is wound out of the upper pulley, thus the change of the distance between the upper pulley and the lower pulley can be realized, and the opening and the grabbing action between two bucket petals can be realized.
Claims (2)
1. A totally enclosed grab bucket is characterized in that: the fully-closed grab bucket comprises a double-jaw bucket body formed by two symmetrical left and right bucket flaps, wherein one side of each bucket flap adjacent to the lower bolster is connected with the lower bolster through a middle pin shaft, the other side of each bucket flap is connected with the lower end of a support rod through a support rod pin shaft, the upper end of each support rod is hinged with the upper bolster, trapezoidal side plates are welded on the front side and the rear side of the upper end of each bucket flap respectively, and a cover plate is welded between the trapezoidal side plates.
2. The fully enclosed grab bucket of claim 1, wherein: the upper pulley of the upper bearing beam is connected with the lower pulley of the lower bearing beam through a steel wire rope.
