Abstract

The invention relates to the technical field of hydraulic control equipment, in particular to a structure-adjustable lifting arm oil cylinder which comprises a cylinder barrel assembly, a magnetic control valve, a piston located in the cylinder barrel assembly and a piston rod assembly fixed to the left side of the piston. According to the lifting arm oil cylinder with the adjustable structure, the top end of the right side of the piston rod assembly is coaxially connected with the angle-adjustable top assembling arm in a sleeving mode, and by adjusting the angle of the top assembling arm, the application range of the lifting arm oil cylinder can be widened; a magnetic control valve is fixed to the opening position of a pressure guide flow channel on the left side of a piston to control guiding of internal oil pressure, so that a first internal telescopic adjusting rod and a second internal telescopic adjusting rod which are located at the top end of a piston rod assembly are controlled to stretch out and draw back, and therefore the angle of a top assembly arm is adjusted; the operation is simple, an additional driving unit is not needed, and meanwhile the overall structure after adjustment is more stable.

Description

technical field [0001] The invention relates to the technical field of hydraulic control equipment, in particular to a structurally adjustable arm lifting cylinder. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. Buffers and exhausts are application specific and others are...
