Abstract

The invention discloses an electro-hydraulic integrated bidirectional locking anti-explosion hydraulic cylinder. The electro-hydraulic integrated bidirectional locking anti-explosion hydraulic cylinder is characterized in that four cavities are formed in a structure part and are a first push cavity, a second push cavity, a third safety cavity and a fourth unlocking cavity correspondingly; a direction valve is switched for locking and unlocking the hydraulic cylinder; the direction valve gains electricity, the hydraulic cylinder is unlocked, a high-pressure oil film is integrated on the fourthunlocking cavity among a cylinder barrel, a left piston and a right piston to form static pressure supporting, the direction valve loses electricity, the hydraulic cylinder is locked, the cylinder barrel and a locking sleeve form strong pressure to be tightly embraced together, meanwhile, hydraulic oil enters the third safety cavity, and hydraulic supporting is formed; and mechanical locking and hydraulic support exist at the same time, the hydraulic cylinder can be safer and more reliable, an unloading read head and a supporting read head can read the pressure of the fourth unlocking cavity and the third safety cavity at any time, the sub-health status of the hydraulic cylinder can be known, and maintenance and updating can be conducted in time.

Description

Technical field: [0001] The invention relates to the technical field of hydraulic cylinder locking methods, in particular to an electro-hydraulic integrated two-way locking explosion-proof hydraulic cylinder. Background technique: [0002] With the popularization of intelligent equipment, the locking of hydraulic cylinders is becoming more and more important. At present, hydraulic cylinders mainly lock the oil cylinders by adding control elements to the control system. The control components include reversing valve locking device, one-way valve locking device, hydraulic control one-way valve locking device, double hydraulic control one-way valve locking device, the above locking devices are all in terms of locking accuracy, locking There are deficiencies in the tight position and locking direction, especially in the direction of the locking position, which cannot meet the design requirements, and there are hidden dangers in terms of safety. Invention content: [0003] In ...
