Embodiment one
See accompanying drawing 1, in the anti-torsion control method of the elevating mechanism of the embodiment of the present invention one offer, elevating mechanism bag
Include the first frequency conversion motor, the second frequency conversion motor;
The anti-torsion control method of elevating mechanism comprises the following steps:
Step 101: described first frequency conversion motor, the second frequency conversion motor receive startup order simultaneously;
Step 102: in described first frequency conversion motor, the second frequency conversion motor running, described in Real-time Collection, first becomes
Frequently the angle-data α of motor1, the angle-data α of the second frequency conversion motor2;
Step 103: obtain | α1-α2| numerical value;
Step 104: control described | α1-α2| the span of numerical value so that the output shaft of described first frequency conversion motor,
The output shaft of the second frequency conversion motor is on same straight line.In the anti-torsion control method of the elevating mechanism of present invention offer,
Elevating mechanism includes the first frequency conversion motor, the second frequency conversion motor.In this case, it is possible to the sharing of load being loaded thing is arrived
First frequency conversion motor, the second frequency conversion motor, now, be able to by the load of the first frequency conversion motor and the second frequency conversion motor alone bear
Reduce, even if the weight being loaded thing is the biggest, it is also possible to ensure the first frequency conversion motor, the second frequency conversion motor alone bear as far as possible
Load.
Additionally, in the anti-torsion control method of elevating mechanism that provides of the present invention and device, be also directed to the first frequency conversion motor
Angle-data α1, the angle-data α of the second frequency conversion motor2Obtain | α1-α2| numerical value, control described | α1-α2| numerical value

α1-α2| numerical value≤first threshold, continuous service the first frequency conversion motor, the second frequency conversion motor.This situation represents, it is possible to use
The traction action of connecting shaft self, and control command makes this | α1-α2| numerical value again revert to first threshold in the range of, this
In embodiment, Second Threshold could be arranged to 8 °.
Wherein, as | α1-α2| numerical value > Second Threshold time, simultaneously send control to the first frequency conversion motor, the second frequency conversion motor
System order, makes the control circuit dead electricity simultaneously of the control circuit of the first frequency conversion motor, the second frequency conversion motor.In this case,
The torsion being considered the first frequency conversion motor and/or the second frequency conversion motor is broken down, continue to run with down final result just
It is that the pulling force causing connecting shaft to be born exceedes its tolerance range and ruptures.Accordingly, it would be desirable to make the control circuit of the first frequency conversion motor,
The control circuit of the second frequency conversion motor dead electricity simultaneously, stops it and continues to run with.
Wherein, | α1-α2| numerical value > Second Threshold time, trigger alarm device send alarm.In this case, phase is worked as
After pass staff perceives associated alarm, it is possible to the first frequency conversion motor and/or the second frequency conversion motor are sent out by the scene of arriving in the very nick of time
Raw fault processes such that it is able to fix a breakdown in the short period of time.The feelings of failure are particularly issued in control command
Under condition, the control circuit dead electricity simultaneously of the control circuit of the first frequency conversion motor, the second frequency conversion motor can be controlled artificially.
Wherein, alarm one in buzzer, flashing lamp, qq message, SMS, wechat message, speech message
Or it is several.
