Description
Technical field
The present invention relates to a kind of hydraulic cylinder more particularly to a kind of major-minor hydraulic oil of the tight boosting hydraulic cylinder of servo-actuated self-locking
Cylinder force-increasing mechanism.
Background technique
The desired thrust that increases of hydraulic cylinder generallys use increase fuel feeding hydraulic system working pressure or increases hydraulic at present
The cylinder diameter of oil cylinder does work thrust to obtain bigger output.
But all there are some problems in both modes:
1, increase the workmanship thrust of hydraulic cylinder using fuel feeding hydraulic system working pressure is increased, will increase oil pump and electricity in this way
The load of machine increases the load of each hydraulic valve and pipeline, and the abrasion that will increase each motion parts in this way increases energy consumption and is unfavorable for saving
Can be environmentally friendly, if increasing hydraulic system working pressure simply will cause the damage of motor and oil pump and hydraulic valve and pipeline, cause
Operator's safety accident and equipment damage.
2, bigger output acting thrust is obtained using the cylinder diameter for increasing hydraulic cylinder, is had in this way in certain installation dimensions
It is required that occasion will will affect use, the cylinder diameter for increasing hydraulic cylinder will cause the waste of raw material resources, increase difficulty of processing
And processing cost, and uneconomical environmental protection.
Therefore, it is badly in need of a kind of technology to improve problem of the existing technology.
Summary of the invention
The case where in view of current hydraulic cylinder reinforcement Shortcomings, the present invention provide a kind of major-minor oil cylinder while increase of doing work
A kind of major-minor hydraulic cylinder force-increasing mechanism of the tight boosting hydraulic cylinder of servo-actuated self-locking of oil cylinder acting thrust.
To solve the above problems, the present invention adopts the following technical scheme that:
A kind of major-minor hydraulic cylinder force-increasing mechanism of the tight boosting hydraulic cylinder of servo-actuated self-locking of the invention, the major-minor hydraulic cylinder
Force-increasing mechanism includes main hydraulic cylinder and the opposition pair hydraulic cylinder being built in main hydraulic cylinder.Pass through increase
The secondary hydraulic cylinder of opposition, major and minor hydraulic cylinder does work simultaneously to be increased main hydraulic cylinder acting thrust and reaches reinforcement
Purpose.This is different from the prior art, bigger to obtain by increasing the cylinder diameter of hydraulic cylinder or improving hydraulic system working pressure
Output do work thrust.
Further, the main hydraulic cylinder includes main hydraulic cylinder cylinder barrel, main hydraulic cylinder piston rod, main hydraulic cylinder
Cylinder head after guide sleeve and main hydraulic cylinder, the front and back position of the main hydraulic cylinder cylinder barrel respectively with main guide sleeve for hydraulic oil cylinder and
Cylinder head connects after main hydraulic cylinder, and the main hydraulic cylinder piston rod is located in main hydraulic cylinder cylinder barrel.
Further, the secondary hydraulic cylinder includes that secondary hydraulic cylinder piston rod, secondary guide sleeve for hydraulic oil cylinder and pair are hydraulic
Oil cylinder piston, the front end of the pair hydraulic cylinder piston rod are cased with secondary guide sleeve for hydraulic oil cylinder, the pair hydraulic cylinder piston rod
Rear end secondary hydraulic cylinder piston is installed.
Further, the inner hole of the main hydraulic cylinder piston rod is secondary hydraulic cylinder cylinder barrel, the pair hydraulic cylinder
Guide sleeve is screwed with main hydraulic cylinder piston rod by screw thread, and the pair hydraulic cylinder piston rod passes through with secondary hydraulic cylinder piston
Screw thread screws.
Compared with prior art, beneficial effects of the present invention:Major-minor hydraulic cylinder force-increasing mechanism is built in main hydraulic cylinder
One opposition pair hydraulic cylinder, major-minor hydraulic cylinder does work simultaneously increases main hydraulic cylinder thrust, is not increasing hydraulic pressure system
System operating pressure and under the premise of not increasing hydraulic cylinder bore size, greatly increases the acting thrust of main hydraulic cylinder, economy
Environmental Safety is reliable.
