The cylinder body of left and right hydraulic jack is hinged by the cylinder shaft that oils with the lower house respectively, the piston rod of the left and right hydraulic jack
It is hinged respectively by the middle part of lower oil cylinder axle and the left and right gripper, the left and right hydraulic jack is provided with safety equalising valve,
The safety equalising valve is connected with swivel joint, and the swivel joint is arranged on the inside of the pivoting support；The upper shell
On be additionally provided with hydraulic control valve for controlling hydraulic motor, left and right hydraulic jack.
The beneficial effects of the utility model are：Hydraulic motor coordinates pivoting support to realize 360 degree of rotations of gripper, captures thing
Expect it is more flexible, it is faster；Safety equalising valve on hydraulic jack has the function that pressurize, avoids under oil circuit damage, crack conditions
Gripper loses support force suddenly, forms grievous injury to operating personnel and article, improves the security performance for grabbing stone implement；With brake
The hydraulic motor of balance weight, strengthen the life-span of hydraulic motor, the security performance of stone implement is grabbed in increase, and hydraulic control valve is by excavator control
Room processed, which moves on to, is grabbed on stone implement, it is only necessary to which the power source of excavator is led to hydraulic control valve by two in-line, oil return line oil pipes, so
Hydraulic control valve delivers power to hydraulic jack by swivel joint and imparts power to hydraulic motor afterwards, without a plurality of oil
The oil pump for routeing excavator control room is led to by being bundled in working arm and grabbed on stone implement, simplifies hydraulic circuit, hydraulic circuit failure
Rate is low, extends hydraulic circuit service life length, maintains easily.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement.
Further, the top of the upper shell is provided with the axle that picks for being used for being connected with working arm of excavating machine.
Beneficial effect using above-mentioned further scheme is that convenience is connected with the working arm of excavator or and quick-replaceable
Connector connects, convenient for installation and maintenance quick.
Further, the inwall of the left and right gripper is provided with rough heel teeth.
Beneficial effect using above-mentioned further scheme is that increase gripper connects with captured material such as marble, steel
Contacting surface is accumulated, and grasping stability avoids sliding, and improves crawl efficiency.
Further, the heel teeth is made using abrasion-resistant stee.
Beneficial effect using above-mentioned further scheme is to increase the wear-resisting intensity of heel teeth, extends the service life of heel teeth.
