Abstract
A kind of method and structure for controlling to grab bucket, one end of upper and lower grab bucket and dipper are connected into coaxial articulated structure, upper and lower grab bucket is connected by quadric chain with dipper respectively, upper cylinder, lower oil cylinder are connected between quadric chain one end of upper and lower grab bucket connection and dipper, motion of grabbing bucket is driven by upper cylinder, lower oil cylinder drives lower grab bucket motion, upper cylinder, lower oil cylinder are controlled by each independent oil circuit control respectively so that upper and lower grab bucket acts and realizes being opened and closed action and the adjustment of grab bucket position respectively.Its advantage is that, because upper and lower grab bucket is controlled by two independent oil circuits respectively, therefore grab bucket rotational angle is big, can be to the gripping of the multiple angles of material, the flexibility of increased grab bucket.
Description
Technical field
The present invention relates to field of engineering technology, more particularly to a kind of control being controlled suitable for excavator grab bucket
The method and structure of grab bucket.
Background technology
Grab bucket is that excavator uses more common one kind in numerous accessories, in forestry, paper-making industry, oil industry, steel industry, is built
Industry, traffic etc. key areas are built for gripping the effect of material, storehouse material, placement material.Grab bucket generally includes grab bucket
With lower grab bucket, the closure of grab bucket is realized by the rotation of grab bucket in control and lower grab bucket.
When current excavator accessory is clam(shell) bucket, mainly there are two kinds of control methods：
Method one：Integrated two oil cylinders in grab bucket, by the flexible of special fluid pressure line control cylinder, to reach in control
Around the rotation of axle, so as to realize the opening and closing of grab bucket, the method oil cylinder is integrated into grab bucket so that grab bucket is very heavy, influences whole for lower grab bucket
Machine stability, while be greatly improved the price of grab bucket, not only high cost, the material of crawl is also limited every time.
Method two：A bearing is welded with below dipper, lower grab bucket is fixed on bearing.Lower grab bucket is fixed with dipper,
The opening and closing of grab bucket can only by upper grab bucket around rotation realize.The method is succinct much compared to method one, it is not necessary to
Special hydraulic control circuit, grab bucket weight is significantly reduced, but shortcoming is also evident from, because only upper grab bucket can turn
Dynamic, the opening and closing of grab bucket receives influence, and grab bucket has significant limitation.
The content of the invention
It is an object of the invention to provide a kind of method and structure of simple, practical control grab bucket.
Solution of the invention is such：
A kind of method for controlling grab bucket, coaxial articulated structure, upper and lower grab bucket point are connected into by one end of upper and lower grab bucket and dipper
Not Tong Guo quadric chain be connected with dipper, it is upper and lower grab bucket connection quadric chain one end and dipper between connect respectively
There are upper cylinder, lower oil cylinder, motion of grabbing bucket is driven by upper cylinder, lower oil cylinder drives lower grab bucket motion, upper cylinder, lower oil cylinder difference
It is controlled by each independent oil circuit control so that upper and lower grab bucket acts and realizes being opened and closed action and grab bucket position respectively
The adjustment put.
A kind of structure for controlling to grab bucket, one end of upper and lower grab bucket is coaxially articulated with dipper, and upper and lower grab bucket passes through four respectively
Linkage connects into the symmetrical structure with dipper as symmetry axis with dipper, in quadric chain one end of upper and lower grab bucket connection
Upper cylinder, lower oil cylinder are connected between dipper, upper and lower oil cylinder is controlled respectively by each independent oil circuit control
System.
It is an advantage of the invention that because upper and lower grab bucket is controlled by two independent oil circuits respectively, therefore grab bucket is rotated
Angle is big, can be to the gripping of the multiple angles of material, the flexibility of increased grab bucket.
Brief description of the drawings
Fig. 1 is that grab bucket oil cylinder is full reduced up and down for the present invention, and structural representation during maximum is opened in grab bucket.
Fig. 2 is full reduced oil cylinder of grabbing bucket under the present invention, and the structural representation of the closure of grab bucket is realized by the elongation of upper grab bucket.
Fig. 3 is that oil cylinder of grabbing bucket under the present invention is stretched entirely, and the structural representation of the closure of grab bucket is realized by the elongation of upper grab bucket.
Specific embodiment
A kind of method for controlling grab bucket, coaxial articulated structure is connected into by one end of upper and lower grab bucket and dipper, upper and lower to grab
Bucket connects into the symmetrical structure with dipper as symmetry axis by quadric chain and dipper respectively, in the double leval jib of upper and lower grab bucket
Upper cylinder, lower oil cylinder are connected between mechanism one end and dipper, motion of grabbing bucket are driven by upper cylinder, under lower oil cylinder drives
Grab bucket motion, upper cylinder, lower oil cylinder are controlled by each independent oil circuit control respectively so that upper and lower grab bucket is acted respectively
And realize being opened and closed action and the adjustment of grab bucket position.
Realize the structure of above-mentioned grab bucket method as shown in Figure 1, 2, 3, upper grab bucket 1, one end of lower grab bucket 2 are coaxially articulated with bucket
Bar 4, upper grab bucket 1, lower grab bucket 2 are connected into symmetrical with the axis of dipper 4 as symmetry axis by quadric chain and dipper 4 respectively
Structure, is connected to upper cylinder 5, lower oil cylinder 3, by each between quadric chain one end of upper and lower grab bucket connection and dipper 4
Upper and lower oil cylinder is controlled respectively from independent oil circuit control so that upper and lower grab bucket can include realizing shown in Fig. 1,2,3
Working condition, grab bucket rotational angle is big, can be to the gripping of the multiple angles of material, the flexibility of increased grab bucket.
Claims (2)
1. a kind of method that control is grabbed bucket, it is characterised in that：One end of upper and lower grab bucket and dipper are connected into and coaxial is hinged knot
Structure, upper and lower grab bucket is connected by quadric chain with dipper respectively, in quadric chain one end of upper and lower grab bucket connection and bucket
Upper cylinder, lower oil cylinder are connected between bar, motion of grabbing bucket is driven by upper cylinder, lower oil cylinder drives lower grab bucket motion, on
Oil cylinder, lower oil cylinder are controlled by each independent oil circuit control respectively so that upper and lower grab bucket is acted and realized out respectively
Close action and the adjustment of grab bucket position.
2. a kind of grab bucket for realizing claim 1 methods described, it is characterised in that：One end of upper and lower grab bucket is coaxially hinged
