A flexible control device for a hydraulic valve

Abstract

The invention relates to a flexible manipulating device for a hydraulic valve. The manipulating device comprises a control end, a high-pressure oil pipe and an execution end; the control end comprises a handle, a manipulating rod, a support A, a pin and a connecting plate, the handle is hinged to one end of the connecting plate through the manipulating rod, and the pin penetrates through the manipulating rod to be fixedly connected with the support A; the high-pressure oil pipe comprises a high-pressure hose, and the two ends of the high-pressure hose are each provided with a piston cylinder and a piston rod; the execution end comprises a support B and a hydraulic control valve, the other end of the connecting plate of the control end is hinged to the piston rod A at one end of the high-pressure oil pipe, the piston rod B at the other end of the high-pressure oil pipe is hinged to a valve rod of the hydraulic control valve, and the piston cylinder A and the piston cylinder B are fixedly connected with the support A and the support B respectively. The flexible manipulating device for the hydraulic valve has the advantages that by means of the manipulating device, the hydraulic control valve is not limited by the operating position, the layout structure of a whole machine can be more flexible, implementation is easy, the cost is low, the structure is simple, the performance is stable, and force feedback is achieved.

Description

technical field [0001] The invention relates to a hydraulic valve control device, in particular to a hydraulic valve flexible control device. Background technique [0002] Construction machinery mostly uses various hydraulic control valves to control the loading, lifting, walking and other actions of goods. [0003] Such as Figure 5 As shown, the operation of the general hydraulic control valve is connected with the hydraulic control valve 3 through the joystick 1 and the connecting rod 2 to control the hydraulic oil circuit. In this control method, the positions of the joystick 1, the connecting rod 2, and the hydraulic control valve 3 are correspondingly limited due to the limitation of the operator and driver's hand positions, thereby limiting the layout and structural design of the entire construction machine. [0004] At present, there are also electro-hydraulic proportional control valves on the market, which control hydraulic valves through solenoid valves, but they...
