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 using 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 being equipped with on dredge boat is not the flat grab bucket of digging, after excavating, on riverbed, can stay grab less than little point, this is unfavorable for the planarization in riverbed.In theory, realize flat digging and can realize by the folding and unfolding of controlling wire rope, this just needs to control very accurately, but, the big machineries such as dredge boat grab bucket quality used is large, and motor used be high-power, in reality, realize accurately control very difficult.
Summary of the invention
Technical problem to be solved by this invention is just to provide that a kind of parallel-moving type is flat digs grab bucket, can utilize guide chute to realize the translation of jaw crown, thereby evade the difficulty of accurate control, and whole device uses simple and well realized the planarization excavating.
For solving the problems of the technologies described above, a kind of parallel-moving type provided by the invention is put down and is dug grab bucket, comprise grab bucket pedestal and a pair of jaw, a pair of jaw is hinged with grab bucket pedestal respectively, realize and excavate action for the folding by between jaw, its special feature is: described grab bucket pedestal side level has four guide chutes, and four guide chutes are arranged up and down between two and be symmetrical, in each guide chute, are equipped with scroll wheel; Described a pair of jaw is hinged with adjacent upper and lower scroll wheel respectively, for by scroll wheel along guide chute translation.
In technique scheme, described a pair of jaw is connected with driving mechanism, for driving opening and closing of a pair of jaw.
Further, described driving mechanism comprises a pair of bucket wire rope and at least one flexible member of closing; The described a pair of upper end of closing bucket wire rope connects outside retractable equipment, lower end and is turned to and be connected with a pair of jaw respectively afterwards by fixed pulley; Described flexible member is also connected with a pair of jaw respectively between a pair of jaw, for the reset of jaw.
Further, the tie point that closes bucket wire rope lower end and jaw described in is the hinge of jaw and lower scroll wheel; Described fixed pulley is one, is positioned on the axis of symmetry of four guide chutes.。
In technique scheme, on described grab bucket pedestal, be connected with hoist rope, for the lifting of the pedestal of grabbing bucket.
Beneficial effect of the present invention is: the setting of guide chute on grab bucket pedestal, make the jaw can be by the scroll wheel in guide chute all the time along guide chute translation, compared with in traditional approach with accurately control realize put down dig easy, cost is also cheaper; Meanwhile, the structure of guide chute is reliable, safe, the very suitable operation that waits complex environment under water.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
In figure: 1-jaw, 2-lower scroll wheel, 3-upper scroll wheel, 4-hoist rope, 5-fixed pulley, 6-close bucket wire rope, 7-guide chute, 8-grab bucket pedestal, 9-flexible member.
The specific embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention are described in further detail.
As shown in Figure 1, a kind of parallel-moving type of the present invention is flat digs grab bucket, comprises grab bucket pedestal 8 and a pair of jaw 1.Have that 7, four guide chutes 7 of four guide chutes are arranged between two up and down and symmetrical in grab bucket pedestal 8 side levels, in each guide chute 7, be equipped with scroll wheel, go up each two of scroll wheel 3 and lower scroll wheel 2.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 by scroll wheel along guide chute 7 translations.
Excavate action for the folding realizing between jaw 1 to complete, 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 after outside retractable equipment, lower end transfer horizontal direction to by fixed pulley 5 and is connected with a pair of jaw 1 respectively, the preferred jaw 1 of tie point of the two and the hinge of lower scroll wheel 2.Above-mentioned flexible member 9 is also connected with a pair of jaw 1 respectively between a pair of jaw 1, for the reset of jaw 1.For realizing the lifting 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 while being drawn high under the effect of bucket wire rope 6 at outside retractable equipment, its lower end drives a pair of jaw 1 along guide chute 7 to the 8 inner side translations of grab bucket pedestal, realize closing of a pair of jaw 1, close in process, jaw 1 remains translation, meanwhile, flexible member 9 pressurized accumulation of energys.When 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.Hoisting and declining of whole grab bucket realizes by the folding and unfolding of hoist rope 4.
Core of the present invention be the to grab bucket setting of guide chute 7 on pedestal 8, makes the jaw 1 can be by the scroll wheel in guide chute 7 all the time along guide chute 7 translations, convenient, realized the flat operation of digging reliably.So its protection domain is not limited to above-described embodiment.Obviously, those skilled in the art can carry out various changes and distortion and 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, it is also feasible adopting conventional type of drive such as hydraulic cylinder etc.; Similarly, grab bucket pedestal 8 is also not limited to adopt hoist rope 4 to realize lifting; If any sufficient space, fixed pulley 5 also can adopt two, is respectively used to two and closes turning to of bucket wire rope 6 etc.If these changes and distortion belong in the scope of the claims in the present invention and equivalent technologies thereof, the present invention is also intended to comprise these changes and is out of shape interior.
