Abstract

The invention belongs to the technical field of hydraulic equipment, discloses a hydraulic cylinder detection device, and aims to solve the problem that oil in a hydraulic cylinder can leak off when the conventional detection device, which cannot comprehensively detect the hydraulic cylinder, is adopted. The hydraulic cylinder detection device comprises a rack, wherein a driving motor is arranged on the rack; the output shaft of the driving motor is connected with a hydraulic pump which is communicated with a hydraulic oil tank; the hydraulic pump is connected with a main control valve; a first oil outlet and a second oil outlet are formed in the main control valve; the first oil outlet is connected with a first oil delivery pipe; the first oil delivery pipe is communicated with the hydraulic oil inlet and outlet of the hydraulic cylinder; the second oil outlet is connected with an oil storage cylinder; an outlet is formed in the oil storage cylinder; a pressure release valve is arranged at the outlet; the pressure release valve is communicated with a one-way valve; the one-way valve is communicated with a hydraulic cylinder inlet / outlet of the hydraulic cylinder.

Description

technical field [0001] The invention relates to the technical field of hydraulic equipment, and in particular relates to a hydraulic cylinder detection device. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has the characteristics of simple structure and reliable operation. When the hydraulic cylinder is used to realize the 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, a piston rod and a sealing device. [0003] For example, the invention patent with the application number 2012...
