Embodiment
As illustrated, the motor for going out aluminium hook lifting part of multifunctional electrolytic machine group, motor top center axle extends tens
Centimetre, and screw thread is put, there is correspondingly sized centre bore in rotation detection disk center, there is internal thread.By rotating disk by being threaded into, then
Rotating disk set screw cap R is screwed into and rotates detection plate with fixed.Then a fixed screw cap S is screwed into, optoelectronic switch is determined
Position plate is inserted in along centre bore A, without internal thread at centre bore A, then is screwed into a fixed screw cap T, adjusts two fixed screw caps
Position, be adjusted to optoelectronic switch can detect rotation detection plate signal untill, allow location-plate to be dangled naturally by gravity, by angle
Steel D and angle steel E is clipped along optoelectronic switch location-plate edge and is welded in out on aluminium dolly floor.Applied on the inside of centre bore A and spread lubrication
Machine oil, in favor of sliding.
When motor rotates, rotation detection plate can be with motor synchronous axial system, and rotating speed is identical, and location-plate does not have internal thread, no
It can rotate, material is thus formed the relative displacement between location-plate and rotation detection plate, optoelectronic switch is in continuous relative displacement
Periodically detect signal and send a signal to processor, processor according to the total number of obtained pulse signal with advance
The data phase product of the distance of each signal period equipment operation measured obtains current equipment and run this side up
Distance length, then allowed with this data and equipment compared with the total stroke length of operation, if the processor that goes beyond the scope will be sent out
Go out signal to continue to run with to executing agency's arrestment, run when equipment and direction change occurs in way, processor will be clear data
Zero recalculates signal summation, recalculates the range ability on new direction.And the range ability calculated divided by
The temporal summation can for receiving these signals calculates the speed of service at that time.Simultaneous processor can also calculate two photoelectricity and hold
It is poor to close the signal time sent, because the installation of two optoelectronic switches is in a straight line, but divides in rotation detection plate
Not Dui Ying two switch punch positions be staggeredly and width it is equal, this result in two switch in each detection cycle
It is to be detected simultaneously by signal to have a bit of time, but as rotation detection plate is towards a direction rotation because detection hole is interlocked
Property necessarily cause one in two switches first to leave detection zone and can't detect signal, and another is still in detection zone
Without departing from as the switch of continuation second of rotation can also leave detection zone and losing signal, but due to two switches in domain
Detection loses signal and priority be present, and time difference can is compared when processor receives two signals and is easily calculated
Motor is towards just or reverse direction operation in this detection cycle, and so as to judge traffic direction, calculating can be
Each cycle judges a direction.The width in non-detection signal area is greater than detection zone non-superimposed zone length and a detection
Switching width and to ensure that two switches have while lose the region of signal.Processor by it is above-mentioned calculate after correlation values with
Speed, direction and the haul distance value inputted during operation compares and makes testing result, the generation once detection is out of order, processor
The disjunction contactor KM1 that will send signals to controlling organization cuts the electrical source of power supply of aluminium hook, and sends signal-off system
Dynamic band-type brake KM2, it is bright to prompt maintainer to examine in time to warning lamp P length on the beam of Multi-function equipments to be simultaneously emitted by a signal
Repair.
