A kind of self-stabilization type hydraulic grab mechanism
Technical field
The present invention relates to grab and put forward machinery manufacturing technology field, particularly to a kind of self-stabilization type hydraulic grab mechanism.
Background technology
Grab bucket is that a kind of folding mainly by two, left and right combination bucket or multiple jaw captures and draw off the suspender of bulk material, grab bucket
Can be divided into fluid pressure type grab bucket and mechanical type grab bucket two big classes by type of drive, fluid pressure type grab bucket itself, equipped with opening-closing structure, is typically used
Hydraulic jack drives, and hydraulic grab Application comparison in hydraulic pressure class special equipment is extensive, such as hydraulic crawler excavator, Hydraulic for lifting load tower etc.;
And mechanical type grab bucket itself is configured without opening-closing structure, is generally driven by rope or connecting rod external force, duplex type can be divided into by operating feature
Grab bucket and single rope grab, be most commonly used that twin rope grab.
Although existing grabbing arrangement kind is various various, but can be frequently seen in daily life and much grab bucket in material grasping process
In, causing grab bucket that the phenomenon that shake material drops occurs owing to the length of material and weight differ, the most often occurring
Junk material injures the phenomenon of workman by a crashing object, existing grabbing arrangement also exist in the course of the work poor stability, material grasping jitter serious and
The inferior defect of inefficiency, and there is potential safety hazard.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of self-stabilization type hydraulic grab mechanism, it is possible to achieve steadily the grabbing of non-jitter
Material function, has that stability is good, material grasping jitter is little, security performance good and work efficiency advantages of higher.
To achieve these goals, the present invention realizes by the following technical solutions: a kind of self-stabilization type hydraulic grab mechanism, including
Moving frame and material grasping side chain, described material grasping side chain is welded on the lower end of moving frame.
