Abstract
The invention relates to a translation-type flat-digging grab bucket, in particular to a grab bucket used in the digging fields such as the field of dredgers. The translation-type flat-digging grab bucket comprises a grab bucket base and a pair of jaw plates, wherein the pair of jaw plates are respectively articulated with the grab bucket base, and the digging action can be realized by the opening and closing of the jaw plates; the translation-type flat-digging grab bucket is characterized in that four guide sliding grooves are horizontally arranged at the side of the grab bucket base, are arranged up and down in pairs and are in bilateral symmetry; each guide sliding groove is internally provided with a roller wheel; and the pair of jaw plates are respectively articulated with the two adjacent upper and lower roller wheels so as to do translation along the guide sliding grooves by virtue of the roller wheels. Due to the arrangement of the guide sliding grooves on the grab bucket base, the jaw plates can always do translation along the guide sliding grooves by virtue of the roller wheels arranged in the guide sliding grooves, and the translation-type flat-digging grab bucket is simpler, more convenient and lower in cost compared with the traditional way in which accurate control is used to realize flat digging; furthermore, a structure of the guide sliding grooves is reliable in running and high in safety, so that the translation-type flat-digging grab bucket is suitable for operation underwater and in other complicated environments.
Description
Technical field
The present invention relates to the grab bucket used in the excavation applications such as dredge boat, refer to particularly that a kind of parallel-moving type is flat to dig grab bucket.
Background technology
Current, the grab bucket that is equipped with on the dredge boat is not the flat grab bucket of digging, after excavating, can stay on the riverbed grab less than little point, this is unfavorable for the planarization in riverbed.In theory, realize putting down and dig and can realize through the folding and unfolding of control wire rope, this just needs control very accurately; Yet; The used grab bucket quality of big machineries such as dredge boat is big, and used motor is high-power, in reality, realize very difficulty of accurately control.
Summary of the invention
Technical problem to be solved by this invention just provides that a kind of parallel-moving type is flat to dig grab bucket, can utilize guide chute to realize the translation of jaw crown, thus the difficulty of having evaded accurate control, and whole device uses simple and has well realized the planarization that excavates.
For solving the problems of the technologies described above; A kind of parallel-moving type provided by the invention is flat to dig grab bucket, comprises grab bucket pedestal and a pair of jaw, and a pair of jaw is hinged with the grab bucket pedestal respectively; Be used for realizing excavating action through the folding between the jaw; Its special feature is: said grab bucket pedestal side level has four guide chutes, and four guide chutes are arranged up and down and bilateral symmetry in twos, are equipped with scroll wheel in each guide chute; Said a pair of jaw is hinged with adjacent upper and lower scroll wheel respectively, is used for through scroll wheel along the guide chute translation.
In the technique scheme, said a pair of jaw is connected with driving mechanism, is used to drive opening and closing of a pair of jaw.
Further, said driving mechanism comprises a pair of bucket wire rope and at least one flexible member of closing; The said a pair of upper end of closing the bucket wire rope connects and is connected with a pair of jaw respectively after outside retractable equipment, lower end turn to through fixed pulley; Said flexible member also links to each other with a pair of jaw respectively between a pair of jaw, is used for resetting of jaw.
Further, the said tie point that closes struggle against wire rope lower end and jaw is the hinge of jaw and following scroll wheel; Said fixed pulley is one, is positioned on the axis of symmetry of four guide chutes.。
In the technique scheme, be connected with hoist rope on the said grab bucket pedestal, the up-down of the pedestal that is used to grab bucket.
Beneficial effect of the present invention is: the setting of guide chute on the grab bucket pedestal, make that jaw can be through the scroll wheel in the guide chute all the time along the guide chute translation, than in the traditional approach with accurate control realize putting down dig easy, cost is also cheaper; Simultaneously, the structure of guide chute is reliable, safe, the very suitable operation that waits complex environment under water.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Among the figure: 1-jaw, 2-following scroll wheel, 3-go up scroll wheel, 4-hoist rope, 5-fixed pulley, 6-close the bucket wire rope, 7-guide chute, 8-grab bucket pedestal, 9-flexible member.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the present invention is done further to describe in detail.
As shown in Figure 1, a kind of parallel-moving type of the present invention is flat to dig grab bucket, comprises grab bucket pedestal 8 and a pair of jaw 1.Have 7, four guide chutes 7 of four guide chutes in grab bucket pedestal 8 side levels and arrange up and down in twos and bilateral symmetry, be equipped with scroll wheel in each guide chute 7, promptly go up scroll wheel 3 and following scroll wheel 2 each two.A pair of jaw 1 is hinged with the right and left, adjacent upper and lower scroll wheel 3,2 respectively, so jaw 1 can be through scroll wheel along guide chute 7 translations.
Excavate action for the folding between the realization jaw 1 to accomplish, a pair of jaw 1 is connected with driving mechanism, and the driving mechanism in the present embodiment comprises a pair of bucket wire rope 6 and at least one flexible member 9 of closing.The a pair of upper end of closing bucket wire rope 6 connects and is connected with a pair of jaw 1 respectively after outside retractable equipment, lower end transfer horizontal direction to through fixed pulley 5, the hinge of preferred jaw 1 of the tie point of the two and following scroll wheel 2.Above-mentioned flexible member 9 also links to each other with a pair of jaw 1 respectively between a pair of jaw 1, is used for resetting of jaw 1.For realizing the up-down of grab bucket pedestal 8, grab bucket pedestal 8 upper ends are connected with hoist rope 4.
The operating principle of the present invention grab bucket is: when closing bucket wire rope 6 externally the effect of retractable equipment is drawn high down; Its lower end drive a pair of jaw 1 along guide chute 7 to grab bucket pedestal 8 inboard translations; Realize closing of a pair of jaw 1, close in the process that jaw 1 remains translation; Simultaneously, flexible member 9 pressurized accumulation of energys.During the grab bucket unloading, loosen and close bucket wire rope 6, a pair of jaw 1 is open under the active force of flexible member 9, realizes opening of a pair of jaw 1.The folding and unfolding that hoists and descend through hoist rope 4 of whole grab bucket realizes.
Core of the present invention be the to grab bucket setting of guide chute 7 on the pedestal 8 makes that jaw 1 can be through the scroll wheel in the guide chute 7 all the time along guide chute 7 translations, and is convenient, realized the flat operation of digging reliably.So its protection domain is not limited to the foregoing description.Obviously; Those skilled in the art can carry out various changes and distortion and do not depart from the scope of the present invention and spirit the present invention; For example: the driving mechanism of jaw 1 is not limited to close the structure of bucket wire rope 6 and flexible member 9, and conventional type of drive such as employing hydraulic cylinder etc. also are feasible; Similarly, grab bucket pedestal 8 also is not limited to adopt hoist rope 4 to realize; If any enough spaces, fixed pulley 5 also can adopt two, is respectively applied for two and closes turning to of bucket wire rope 6 etc.If these changes and distortion belong in the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and is out of shape interior.
