Detailed description of the invention
As Figure 1-4, this hydraulic pressure spring operating mechanism includes operational module 1-1, power plant module 1-2, monitoring module 1-
3, energy-storage module 1-4, control module 1-5；Working cylinder 2-1, combined floodgate side set 2-2, combined floodgate cushion collar 2-3, piston rod 2-4, separating brake
Cushion collar 2-5, separating brake side set 2-6；Separating brake electromagnetic valve 3-1, combined floodgate electromagnetic valve 3-2, spool 3-3, valve body 3-4；Loaded cylinder 41
With disc spring 42；Manual lever 5-1, relief valve 5-2, travel switch 5-3.
The working cylinder 2-1 of power plant module provides the connecting interface with other module, and operational module 1-1 passes through separating brake electromagnetic valve
The folding of 3-1 and combined floodgate electromagnetic valve 3-2 controls the piston rod 2-4 of power plant module 1-2, the piston rod 2-4 of power plant module 1-2 and
Combined floodgate cushion collar 2-3 constitutes integrated type multi-stage buffer system.
Control module 1-5 is made up of with secondary valve one-step valve, and one-step valve is 2 separating brake electromagnetic valve 3-1 and 1 combined floodgate electromagnetism
Valve 3-2, secondary valve is made up of valve body and the spool that can realize commutation function.
Energy-storage module is made up of loaded cylinder 41 and disc spring 42,3 loaded cylinders 41 in 120 ° with working cylinder 2-1 phase
Even.
Its operation principle is: when closing operation, combined floodgate electromagnetic valve 3-2 energising action, and two grades of reversal valves are made at hydraulic oil
It is transformed into closing position under with, hydraulic oil is injected into below the piston of working cylinder 2-1, at the work of piston upper and lower both sides differential force
With lower promotion piston upwards and drive chopper to turn to closing position.
When sub-switching operation, separating brake electromagnetic valve separating brake electromagnetic valve 3-1 energising action, two grades of reversal valves are under hydraulic oil effect
Being transformed into open position, below the piston of working cylinder 2-1, hydraulic oil is injected into low-pressure reservoir, at piston upper and lower both sides differential force
Effect is lower promotes piston to move downward and drive chopper to turn to open position.
When declining due to the breaking-closing operating build-up of pressure of mechanism and change disk spring compress variation, in monitoring module
Under the effect of limit switch, motor pump is suppressed automatically, makes oil pressure in high-voltage oil cavity raise, when reaching MTP, and motor
Oil pump pump trip.
