Describe the present invention now with reference to the accompanying drawings in detail:
Fig. 1 illustrates according to the device for the safe operation lifting mechanism of the present invention.
Fig. 2 illustrates the zones of different of lifting mechanism motion.
Fig. 3 illustrates another embodiment according to device of the present invention.
The specific embodiment
Fig. 1 illustrates for the essential parts of the safe operation of lifting mechanism.Two drive motor 1 all drive an axle, are provided with a for example flake down tube at described axle.Be installed in for these two motors on the both ends of axle, wherein, structural form and transmission type depend on corresponding space requirement.For clarity sake, the connection structure of two drive motor is not shown in figures.
Other according to embodiments of the invention in, may (utilizations) such structural change for lifting mechanism is moved also in mode according to the present invention: in described structural change two drive motor 1 by directly be installed in successively comprise the flake down tube spool a side on.
Two drive motor 1 are equipped with a drg 2 respectively.Described drg is normal in service as shutting down drg.Especially when being in, drive motor 1 activates described shutdown drg in the time of maybe should remaining static.
Drive motor 1 and coupled drg 2 are designed to form the system of a redundancy.Each drive motor-brake unit is designed to, and irrespectively lifting mechanism is remained on (current) height and position together with present load with other drive motor-brake unit in the time of can enough engaging/work (einfallen) at drg.
The electromechanical transducer 3 that is installed in respectively on the drive motor 1 for example is absolute value transducer, and described absolute value transducer can be determined revolution and rotor-position with fine resolution.
Drive motor 1 is concurrently by public frequency converter 4 feeds.Another according to embodiments of the invention in, frequency converter 4 is equipped with braking resistor 5.Normally in service, the B.P. that produces when load descends can be transfused to braking resistor 5.
Carry out adjusting to drive motor 1 by the signal of the electromechanical transducer 3 of at least one drive motor, described signal is transferred to frequency converter 4 by electromechanical transducer circuit 18.
Also be connected with contactless switch 7 between frequency converter 4 and drive motor 1 respectively, described contactless switch 7 can cut off each drive motor 1 individually.
Control by 12 pairs of lifting mechanisms of controller, described controller 12 is connected with frequency converter 4 by communication line 17.
Two drive motor 1 are designed to aspect big or small at power and structure together with drg 2 and corresponding frequency converter 4, and feasible only drive motor 1 its corresponding drg 2 just is enough to move lifting mechanism.Redundancy is the key character of safe operation lifting mechanism.Frequency converter 4 is designed so that can be at least to two drive motor feeds by described frequency converter 4.
In order to improve safety, the function to the drg 2 of drive motor 1 detects at regular intervals.Employed drg 2 is a kind of spring pressure drgs, and it engages under no current state.When connecting drive motor 1, electromagnet is energized in the drg 2, makes drg 2 form air gap.For drg 2 is carried out function test, drg 2 is engaged, connect braking driving controller 9 by relay 10 for this reason.Controller 12 is responsible for the coordination of function test, and described controller 12 is connected with described relay 10 by control path 16.Lifting mechanism is brought into operation.
Utilize two electromechanical transducers 3, be that angular-motion transducer detects two drive motor 1 angular transposition separately, try to achieve corresponding rotating speed thus.In two electromechanical transducers 3 one is connected with frequency converter 4 by electromechanical transducer circuit 18, in order to provide the adjusting actuating device required feedback signal.The electromechanical transducer signal is transferred to monitor module 6 to carry out other analysis by frequency converter 4.Another electromechanical transducer 3 directly is connected with monitor module 6 by electromechanical transducer circuit 18.
Analog signal with two electromechanical transducers 3 in monitor module 6 compares mutually, thereby can intervene system when departing from the anticipated value of setting.
Normally in service, lifting mechanism can move between a upper terminal position and a lower terminal position, and this upper terminal position provides by limit switch 11, and this lower terminal position is predetermined and obtained by the signal of electromechanical transducer 3 by higher controller 12.
In another embodiment, two terminal locations, be that upper terminal position and lower terminal position all pass through limit switch 11 regulations.
In another embodiment, the corresponding adjusting all passed through in the controller 12 of two terminal locations determines.At this, the position of lifting mechanism is derived by the motor sensor signal.
Normally in service, carry out the lifting of load with the full functionality that controlled driving can be provided.Therefore different speed slopes can occur and mainly be acceleration/accel slope or deceleration/decel slope.The energy that discharges when braking is derived or is alternatively fed back in the electrical network by braking resistor.
For normal operation, detect the function of two drgs 2 with the time gap of determining.For this reason, one after the other connect two relays 10 in service continuously by controller 12, thereby make drg 2 under currentless situation, engage.When drg 2 engages, the signal of electromechanical transducer 3 and the anticipated value of setting are compared.
In the scope of braking test, also there is such possibility, namely judges between electromechanical transducer signal and the corresponding anticipated value to have deviation.Described deviation for example may cause owing to the deficiency of the brake action of the drg of testing 2.If the departure that obtains from the comparison of electromechanical transducer signal and anticipated value, is thought then that lifting mechanism is dangerous greater than a threshold value of determining and is thought that test is not passed through.In this case, read out instrument shows warning or reports to the police that described warning can be transferred to higher controller by communicator.
Fig. 2 illustrates possible lifting mechanism position 20, and these lifting mechanism positions can be corresponding to work area 21 or can be corresponding to safety zone 22.
If in lifting mechanism 23, implement the braking test, then make lifting mechanism drive in the described safety zone 22 and enforcement braking test.If test is successfully carried out, then lifting mechanism can continue its work, especially enters in the work area 21 to move.For the situation of braking test crash, then load 24 is lowered in the safety zone.Can on this position, keep in repair with the drg of simple, safe mode to et out of order.Subsequently, lifting mechanism 23 can move again after again a braking test.
Fig. 3 illustrates another embodiment according to device of the present invention.The layout of actuating device is identical with the description of Fig. 1 with configuration.
Fig. 3 illustrates the connection line of motor 1 and drg 2, and they directly are not electrically connected with frequency converter 4 or supply line 14. Contactless switch 7,8,9,10,31 shown in the figure, 32 forms a network, and this network forms three aspects of the vital circuit of lifting mechanism.
For connecting the signal that contactless switch 9 needs one are provided by monitor module 6.For this signal is transferred to contactless switch 9, must connect contactless switch 32 by frequency converter 4.If contactless switch 32 is connected, then the signal of monitor module 6 is applied on the contactless switch 10.If contactless switch 10 is connected by controller 12, then it works to connect contactless switch 9, makes drg 2 open/not engage thus.
Guaranteed in the above described manner only under following situation, just can open drg:
-apply power supply voltage,
-in monitor module 6, there is not a failure report,
-frequency converter 4 can move,
-and controller 12 specify opening of drgs.
Therefore this network is suitable for the logic operation of described running state.
By this cascaded structure, compare the safety that existing system has improved system significantly.
Come starter motor 1 according to multi-stage process equally.At first, must be with frequency converter 4 starter motors 1, this is not shown in the accompanying drawings.Insert contactless switch 7 in the supply line of motor, described contactless switch 7 is by contactless switch 31 switches.For this reason, must apply one by 6 pairs of contactless switchs 31 of monitor module is the signal of prerequisite there not to be any safety problem, only could connect contactless switchs 31 by controller 12 under these circumstances, thereby connects contactless switch 7 and can make the motor operation.
Motor only could move under following situation:
-provide power supply voltage by frequency converter,
-in monitor module 6, there is not a failure report,
-controller 12 is exported a connection signal for motor.
Therefore this network is suitable for the logic operation of described running state.
In the present embodiment, possibility by independent each parts of control also realized can be simply, the braking implemented fast tests.In case lifting mechanism drives in the safety zone 22, just engage brake 2 is also passed through frequency converter 4 to motor 1 feed in actuating device.If judge that when breakdown torque/breakdown torque appears in electromechanical transducer 3 non-angular changes, think that then drg is in the following safety of described breakdown torque.
Implement described test serially in all comprise the actuating device of corresponding drg, wherein after tested drg is not opened respectively.
