The working method of the utility model high power hydraulic spring operating mechanism:

The energy storage course of work: during described high power hydraulic spring operating mechanism energy storage; Motor 125 drives bent axle 130 and rotates; 134 work of bent axle 130 pressure oil pumps; Oil pump 134 pumps the hydraulic oil in the fuel tank 17 from oil pump 134 oil-outs; Pump into time-delay valve opening 141, the working cylinder high pressure oilhole 36 of working cylinder 1 upper surface, flow into working cylinder high-voltage oil cavity 34, loaded cylinder high-pressure chamber 37 and valve pocket high pressure chest 54 through the horizontal high pressure oilhole of cylinder body 91, crescent oil circuit d95, crescent oil circuit e96 again, along with the hydraulic oil in the loaded cylinder high-pressure chamber 37 increase; The annulus table top in the loaded cylinder 6 and the annulus table top of working cylinder 1 cylindrical deviate under the hydraulic oil effect; Loaded cylinder 6 is moved downward, and dish spring group lower flange 11 is fixed on the working cylinder 1 with working cylinder lower flange 12, so dish spring upper flange 5 compact disc spring groups 7 make dish spring group 7 elastic force release and can store.

The combined floodgate course of work: described high power hydraulic spring operating mechanism is in separating brake energy storage state; In the time of need doing closing operation; After the making electromagnet energising, making electromagnet 144 impacts combined floodgate valve rod c67, and combined floodgate valve rod c67 can drive steel ball b66 when moving downward; Ball holder b65; Combined floodgate valve rod b62, steel ball a60 moves downward together, can make combined floodgate valve seat a57; The mesopore of combined floodgate valve seat 63b communicates; The hydraulic oil of loaded cylinder high-pressure chamber 37 and 36 li of working cylinder high pressure oilholes flows into spool signal chambeies 51 from valve pocket high pressure chest 54, a step valve hydraulic oil hole 56, combined floodgate valve seat a oilhole 82, combined floodgate valve seat b63 centre bore, combined floodgate valve seat b cross-drilled hole 147, one-level valve signal oilhole 55 successively, after spool signal chamber 51 is full of hydraulic oil, spool 46 can move upward until spool 46 upper ends and valve pocket 39 near; This moment, the hydraulic oil of 54 li of loaded cylinder high-pressure chamber 37, working cylinder high pressure oilhole 36 and valve pocket high-pressure chambers flowed into valve pocket signal chamber 52, working cylinder signal oil pocket 35 from the Y type centre bore of spool 46; Loaded cylinder high-pressure chamber 37, working cylinder high pressure oilhole 36, valve pocket high-pressure chamber 54, valve pocket signal chamber 52 and working cylinder signal oil pocket 35 all are communicated with the formation high pressure at this moment, after working cylinder signal oil pocket 35 is full of high-pressure and hydraulic oil, piston rod 13 are moved upward fast, and fitting with combined floodgate cushion collar 29 until piston rod 13 is close to; Thereby mechanism is closed a floodgate; After making electromagnet 144 outages, steel ball a60 and steel ball b66 seal the bottom face mesopore of combined floodgate valve seat b63 and combined floodgate valve seat c71 once more under the effect of spring a58 and spring b64, cut off a step valve combined floodgate oil circuit.

The separating brake course of work: described high power hydraulic spring operating mechanism is in the energy storage state that closes a floodgate; In the time of need doing sub-switching operation; Impact separating brake valve rod e81 after tripping electromagnet 145 energisings; Separating brake valve rod e81 presses downwards and drives steel ball d76; Ball holder d75 moves downward together, and the mesopore of separating brake valve seat e79 and separating brake valve seat d73 is communicated, and this moment, spool signal chamber 51 hydraulic oil was got back to 17 li of fuel tanks from one-level valve signal oilhole 55, separating brake valve seat d oilhole 83, separating brake valve seat e79 centre bore, separating brake valve seat e oilhole 85, a step valve low pressure oil hole 72, crescent oil circuit c 94, time-delay valve pocket c oilhole 108, time-delay valve pocket d oilhole 117, time-delay valve pocket d mesopore, time-delay pressure release oilhole 89, working cylinder low pressure oilhole 86 successively at last; Spool signal chamber 51 loses high pressure; Lower stress changes on the spool 46, spool 46 move downward fast until spool 46 and cylinder stifled 44 near, this moment, working cylinder signal oil pocket 35, valve pocket signal chamber 52 and valve pocket low pressure chamber 53 were communicated with; The high-pressure and hydraulic oil that working cylinder signal oil pocket 35, valve pocket signal chamber are 52 li flows into the working cylinder low pressure oilhole 86 last fuel tanks 17 that get into from valve pocket low pressure chamber 53, crescent oil circuit f146; After working cylinder signal oil pocket 35 high-pressure and hydraulics oil flows into fuel tank 17, piston rod 13 is moved downward under the 34 hydraulic oil effects of working cylinder high-voltage oil cavity fast, fitting with splitting lock cushioning cover 38 until piston rod 13 is close to; Thereby make mechanism's separating brake; After tripping electromagnet 145 outages, steel ball d76 seals separating brake valve seat e79 bottom face mesopore once more under the effect of spring d74, cuts off a step valve separating brake oil circuit.

Time-delay process: after the completion of closing a floodgate, give sub-gate signal separating brake immediately immediately even time-lag action is a mechanism, must behind certain hour, just can carry out the separating brake action.The high power hydraulic spring operating mechanism of the utility model uses theory of mechanics to accomplish delay function, promptly controls the closure of a step valve separating brake oil circuit and open-minded.

The hydraulic oil that valve pocket high pressure chest 54, working cylinder high pressure oilhole 36 are full of after mechanism's gate-dividing state energy storage flows into the mesopore of time-delay valve pocket a97 from crescent oil circuit b93 and time-delay valve high pressure oilhole 103; Time-delay spool 101 is moved upward to be close to time-delay valve pocket a97 until time-delay spool 101 tops; Time-delay valve steel ball 111 is at the centre bore of the effect lower seal time-delay valve pocket d118 of time-delay valve spring 113; Thereby close a step valve separating brake oil circuit, can't separating brake.

After mechanism accomplish to close a floodgate during promptly in "on" position; Loaded cylinder high-pressure chamber 37, working cylinder high pressure oilhole 36, valve pocket high-pressure chamber 54, valve pocket signal chamber 52 and working cylinder signal oil pocket 35 all are communicated with the formation high pressure; Hydraulic oil flows into the centre bore of time-delay valve pocket a97 through valve pocket oilhole a40, time-delay valve pocket a oilhole 98; Under the sealing function of time-delay valve pocket a sealing ring 99 and time-delay valve core seal ring a100, time-delay spool 101 is moved downward until time-delay spool 101 bottoms back down time-delay steel ball 111, the required time of this motion process of time-delay spool 101 is exactly delay time; Thereby open a step valve separating brake oil circuit, just can separating brake.

Described delay time is controlled the distance of time-delay valve pocket d118 entering time-delay valve pocket c110 and is controlled through the external screw thread of time-delay valve pocket d118.

After described high power hydraulic spring operating mechanism combined floodgate or the separating brake action; The hydraulic oil that working cylinder high-voltage oil cavity 34, working cylinder high pressure oilhole 36 and loaded cylinder high-voltage oil cavity are 37 li can get into working cylinder signal oil pocket 35 or working cylinder low pressure oilhole 86 flows back to fuel tank 17 again; Make in the loaded cylinder 6 on the annulus table tops and working cylinder 1 outer wall the annulus daylight opening DLO from reducing; Be the loss of dish spring group 7 energy, after energy loss is a certain amount of, need energy storage once more.

Experiment proof: the utility model hydraulic spring grease cup actuating machine; The advantage that it adopts the control valve module to be integrated in the design in the working cylinder 1 has been eradicated the persistent ailment of agent structure in the past; Improve the mechanically stable property and the sealing reliability of high power hydraulic spring operating mechanism comprehensively, improved the stability that product uses.
