Detailed description of the invention
As shown in Figure 1, a kind of numerical control hydraulic mute type home lift, car 18 is connected with single acting oil cylinder 10 by steel rope 14; The concrete hydraulic circuit structure be connected with single acting oil cylinder 10 is: servomotor 4 connecting fluid press pump 3, and the lower end oil inlet and outlet of Hydraulic Pump 3 is connected with fuel tank 1, and the upper end oil inlet and outlet passing ratio flow-controlling gate 6 of Hydraulic Pump 3 connects the hydraulic fluid port of single acting oil cylinder 10; Oil circuit between single acting oil cylinder 10 and operated proportional flow control valve 6 is arranged hydraulic pressure master cock 7.
Described Hydraulic Pump 3 is connected by filter 2 with between fuel tank 1.
The upper end oil inlet and outlet of described Hydraulic Pump 3 also connects safety overflow valve 5, and safety overflow valve 5 end connects fuel tank 1.
Oil circuit between described single acting oil cylinder 10 and operated proportional flow control valve 6 is provided with the compression indicator 9 with pressure meter switch 8.
Described single acting oil cylinder 10 is fixed in hoistway frame 20, and the lower end of single acting oil cylinder 10 is provided with fixed pulley group 19, and hydraulic stem 11 end above single acting oil cylinder 10 connects running block 12; In hoistway, be provided with two track adjusting wheels 13, steel rope initiating terminal 16 is fixed in hoistway, and after walking around running block 12 and fixed pulley group 19 successively, walks around be connected with car 18 from the upper end of two track adjusting wheels 13.
The control method of numerical control hydraulic mute type home lift, comprises the following steps:
1) when elevator receives climb command, servomotor 4 hydraulic control pump 3 forward accelerates to rotate gradually, operated proportional flow control valve 6 is opened, hydraulic oil enters in single acting oil cylinder 10, hydraulic stem 11 upwards accelerates to rise gradually, drive car 18 to rise by steel rope 14, ascending velocity change is controlled by servomotor 4; If because operated proportional flow control valve 6 relative servomotor 4 delayed unlatching can be set when returning heavy phenomenon instantaneously when oil pump is let out for 3 times and made car produce and open and apply the suitable change in electric of operated proportional flow control valve 6, until the comfort level of car 18 lifting process is satisfied;
2) elevator be raised to pre-off-position put before time, servomotor 4 is decelerated to gradually and stops operating, operated proportional flow control valve 6 oil circuit control close, car 18 stop motion; If close in advance and apply the suitable change in electric of operated proportional flow control valve 6 because operated proportional flow control valve 6 relative servomotor 4 can be set when producing back heavy phenomenon when oil pump is let out for 3 times and made car 18 stop instantaneously, until the comfort level of car 18 lifting process is satisfied;
3) when elevator receives decline instruction, operated proportional flow control valve 6 is opened, oil circuit is in logical state, servomotor 4 rotates for oppositely accelerating gradually, car makes the hydraulic stem 11 of single acting oil cylinder 10 accelerate retraction gradually under gravity, hydraulic oil is return through former road, and descending speed change is controlled by servomotor 4; If open and apply the suitable change in electric of operated proportional flow control valve 6 because operated proportional flow control valve 6 relative servomotor 4 can be set when producing and return heavy phenomenon instantaneously when oil pump is let out for 3 times and made car 18 decline and open, until the comfort level of car 18 lifting process is satisfied simultaneously;
4) elevator drop to pre-off-position put before time, servomotor 4 is decelerated to gradually and stops operating, operated proportional flow control valve 6 oil circuit control close, car 18 stop motion; If close and apply the suitable change in electric of operated proportional flow control valve 6 because operated proportional flow control valve 6 relative servomotor 4 can be set when oil pump is let out for 3 times and made car 18 stop not soft phenomenon to produce, until the comfort level of car 18 lifting process is satisfied simultaneously;
5) let out phenomenon for 3 times due to oil pump to exist, when when rotating speed is very slow, theoretical instant discharge capacity is less than instant spillage, car 18 inevitable sedimentation under gravity, affects the mildness that car 18 opens, stops, affects the comfort level that in lifting process, people feels; Let out for 3 times comfort degree situation in car 18 lifting process according to oil pump, the relative servomotor 4 of passing ratio flow-controlling gate 6 opens and closes in advance or the delayed change control flowrate variation applying electric signal with passing ratio flow-controlling gate 6 that opens and closes is revised comfort level in car 18 lifting process;
6) when overloading and when oil pressure exceedes the setting value of hydraulic pressure master cock 7, hydraulic pressure master cock 7 sends signal control servomotor 4 and can not work, operated proportional flow control valve 6 can not be opened, only need load reduce, when oil pressure is retracted into below the setting value of hydraulic pressure master cock 7, servomotor 4 just can work, operated proportional flow control valve 6 could be opened, and plays limit for tonnage effect.
Its working process is: Hydraulic Pump 3 is under servomotor 4 drives, and hydraulic oil is inhaled into Hydraulic Pump 3 end interfaces through filter 2 from fuel tank 1, and discharges from Hydraulic Pump 3 upper port.When pressure exceedes setting value, safety valve 5 is opened hydraulic oil and is let out oil sump tank 1, within making pressure be limited to setting value, plays safety control effect.Operated proportional flow control valve 6 and servomotor 4 are controlled by control system, when servomotor 4 forward revolves, operated proportional flow control valve 6 is opened, hydraulic oil from Hydraulic Pump 3 upper port through operated proportional flow control valve 6, enter oil out port through single acting oil cylinder 10 lower end and enter single acting oil cylinder 10, promote hydraulic stem 11 and the rising of 12 groups, movable pulley.Steel rope 14 drives car 18 by running block 12, fixed pulley group 19 and two track adjusting wheels 13, and rises in the speed of hydraulic stem 11 with the integral multiple of 2.When servomotor 4 stops, operated proportional flow control valve 6 is closed, and car 18 stops, and is in closed condition thus prevents car 18 from letting out generation sedimentation deformation phenomenon because hydraulic oil returns, ensure the running precision of elevator and normal use due to operated proportional flow control valve 6.When servomotor 4 contrarotation, operated proportional flow control valve 6 is opened, and car 18 makes hydraulic stem 11 bounce back under gravity, and the former road of hydraulic oil is return, and car 18 declines.The change of the ascending, descending speed of car 18 jointly controls realization by servomotor 4 hydraulic control pump 3 fuel feeding or recirculating oil quantity change and operated proportional flow control valve 6.Interface oil circuit connecting fluid pressure pressure master cock 7 on operated proportional flow control valve 6, when when car 18 overloads, namely when oil pressure exceedes the setup pressure value of hydraulic pressure master cock 7, hydraulic pressure master cock 7 sends signal control operated proportional flow control valve 6 and is in closed condition, and must not open and control servomotor 4 must not rotate.Only have after how overload is laid down, when oil pressure returns to below the setup pressure value of hydraulic pressure master cock 7, operated proportional flow control valve 6 could be opened, servomotor 4 just can work.Opened by pressure meter switch 8 when needs display oil pressure, compression indicator 9 shows pressure.
Let out phenomenon there is car certainty sedimentation under gravity when the theoretical discharge capacity immediately when rotating speed is very slow is less than instant spillage because oil pump returns, affect the comfort level in car lifting process.Returning according to oil pump lets out comfort degree situation in car lifting process, and the relative servomotor 4 of passing ratio flow-controlling gate 6 opens and closes in advance or the delayed change control flowrate variation applying electric signal with passing ratio flow-controlling gate 6 that opens and closes is revised comfort level in car 18 lifting process.
