Multifunctional hydraulic manupulator

The utility model relates to a hydraulic manipulator which consists of a manipulator and a hydraulic control box. The manipulator comprises a pedestal, a rotating body, a post arm, a front arm, a paw and a support oil cylinder. A hydraulic motor and a transmission mechanism are positioned inside the pedestal; the rotating body driven by a transmission mechanism is positioned on the top of the pedestal; the post arm articulated with the rotating body is supported and driven by a cylinder arranged between the rotating body and the transmission mechanism; the front arm articulated with the post arm is driven by the cylinder arranged between the transmission mechanism and the post arm; the paw articulated with the front arm is driven by the cylinder arranged between the transmission mechanism and the front arm; the support cylinder is fixed on the pedestal. The manipulator has the advantages of small volume, reasonable structure, being capable of meeting requirements for special working environment in mine because that firstly, the manipulator can be used as an auxiliary equipment of coal getting machinery to realize fast, effectively undercut and open gap at dead areas of coal mining, bringing coal mining machinery into full play; secondly, the manipulator can be used as mechanic appliance to recover the preset I-shaped steel sheds positioned at passageway of the working face end, recover single hydraulic pillar, clean passageway float coal and rock residue, etc.
