Embodiment
As shown in the figure, the motor going out aluminium hook lifting part of multifunctional electrolytic machine group, motor top center axle extends tens centimetres, and puts screw thread, rotates and detects the center pit that there is corresponding size in disk center, have internal thread.By rotating disk by being threaded into, then rotating disc set screw cap R is screwed into fixing rotation detection dish.Then a fixed screw cap S is screwed into, by optoelectronic switch location-plate centrally hole A be inserted in, center pit A place is without internal thread, be screwed into a fixed screw cap T again, the position of adjustment two fixed screw caps, adjust to till optoelectronic switch can detect the signal rotating detection dish, allow location-plate lean on gravity naturally to dangle, angle steel D and angle steel E is clipped along optoelectronic switch location-plate edge and is welded in out on aluminium dolly floor.Be coated with inside center pit A and spread lubricating oil, be beneficial to slide.
When motor rotates, rotate detection dish to rotate with motor in synchrony, rotating speed is identical, location-plate does not have internal thread, can not rotate, the relative displacement that material is thus formed location-plate and rotate between detection dish, optoelectronic switch periodically detects signal and signal is sent to processor in continuous relative displacement, the data phase product of the distance that processor runs with each signal period equipment measured in advance according to total number of the pulse signal obtained obtains current equipment in the distance length that this side up has run, allow compared with the total stroke length run again with these data and equipment, if gone beyond the scope, processor will send signal to topworks's arrestment continuation operation, direction change is there is when equipment runs in way, processor will recalculate signal summation zeros data, recalculate the range ability on new direction.And the range ability calculated just can be calculated travelling speed at that time divided by receiving the temporal summation of these signals.It is poor that simultaneous processor also can calculate the signal time that two optoelectronic switches send, because the installation of two optoelectronic switches is in a straight line, but be staggered and width is equal at the punch position rotating corresponding two switches respectively on detection dish, this just causes two switches in each sense cycle, have a bit of time is signal detected simultaneously, but rotate because one in two switches must be caused first to leave surveyed area for detect aperture staggering towards a direction along with rotating detection dish and can't detect signal, and another does not still also depart within a detection region, along with continuation second switch rotated also can leave surveyed area and loss signal, but there is successively property because two switches detect loss signal, comparing the mistiming when processor receives two signals just can to calculate in this sense cycle motor easily towards just or reverse direction operation, thus judge traffic direction, calculating can each cycle judge first power to.The width in non-detection signal district be greater than surveyed area non-superimposed zone length and a detector switch width and to ensure that two switches have the region of loss signal simultaneously.Processor by above-mentioned calculate correlation values after make testing result compared with the speed inputted during operation, direction and length of stroke value, once detect that fault occurs, the disjunction contactor KM1 sending a signal to control gear is cut off out the electrical source of power supply of aluminium hook by processor, and send signal at stop braking brake KM2, send a signal long bright to point out maintainer to overhaul in time to warning lamp P on the beam of Multi-function equipments simultaneously.
Monitor disk center height is overhead 400MM, the diameter going out aluminium hook lifting drum is 650MM, and monitor disk radius 385MM is 2250MM according to can be calculated girth, W as shown in the figure in monitor disk, X, Y partial width is the width of 9MM, Z is 18MM, W, X, Y, Z tetra-part be a complete monitoring periods width, summation is 45MM, to can be calculated can get 50 holes with girth 2250 divided by one-period width 45, and namely monitor disk is often turned around and can be carried out 50 monitorings.
Going out aluminium hook drum diameter is 650MM, be 2041MM by can be calculated girth, because the wire rope quick pushing manipulation going out aluminium hook show that drum often rotates 1 meter, hook is elevated 1/4 meter, this just show that drum revolves the hook that turns around and will be elevated 508MM, also just show that each monitoring periods hook of hook can be elevated 10.16MM, both hook be often elevated 1.016 centimetres will be once monitored, neglect the actual approximately hook of very little mantissa to be often elevated 1 centimetre and will to monitor once, 1 centimetre of one scope detected meets the monitoring of the lifting action of the large gib head of 32 tons of dead weight capacity 1 meter high completely.
The monitoring switch of the NBN8-18GM50-E0 model extraordinarily lied prostrate, monitoring distance is 12MM, and the screw thread of afterbody Adjustable Range is that 50MM is long, and can adjust the position of switch to suitable position in front and back, implement very easy, the diameter of switch is 18MM.
Be understandable that, above about specific descriptions of the present invention, the technical scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
