Explanation and introduction.
For the electric motor-trolley with two cover gearings.Motor side shaft coupling sensor and deceleration pusher side shaft coupling sensor (this example all adopts common proximity switch or magnetic switch SQ1 and SQ2) are arranged in adjustable installing bracket, motor side shaft coupling trigger element and deceleration pusher side shaft coupling trigger element (common iron block or magnetic patch) are arranged on motor side shaft coupling and deceleration pusher side shaft coupling respectively, shaft coupling often turns around, can trigger sensor SQ1 and SQ2 once, installation requirement is when shaft coupling runs well, and the trigger pip of sensor SQ1 and SQ2 of its both sides sends simultaneously and disappears simultaneously.
When shaft coupling runs well, proximity switch or magnetic switch SQ1 and SQ2 connect simultaneously or disconnect (see figure 3) simultaneously, with reference to the electric control loop schematic diagram shown in Fig. 2, the timing relay KT on known 3rd branch road cannot be energized adhesive, namely cannot transmit fault-signal.
When shaft coupling ruptures, because motor side shaft coupling velocity of rotation is no longer the same with deceleration pusher side shaft coupling velocity of rotation (especially in the speed regulation process accelerated and slow down, see Fig. 4), cause that SQ1 and SQ2 is closed or trip time is different, make the timing relay KT energising adhesive on the 3rd branch road, after arriving the time that guidance panel sets, time delay turn on-switch KT will close, power transfer relay KA3 is energized, malfunction indicator lamp HL energising simultaneously on guidance panel brightens, K switch A3 closes, power transfer relay KA3 is energized self-insurance, until reset button SB is pressed after Failure elimination.
The effect of time delay engage relay KT is the fault false triggering that the slight asynchronous signal preventing proximity switch or magnetic switch SQ1 and SQ2 from producing causes, and delay time is set by the time relay setting knob on guidance panel.After fault-signal occurs, malfunction indicator lamp HL is energized always and brightens, only after shaft coupling fracture defect is eliminated, again adjusted the position of proximity switch or magnetic switch SQ1 and SQ2 by adjustable installing bracket 7, after pressing failure reset button SB, malfunction indicator lamp just can power-off restoration.
Because fault-signal is transmitted by relay, therefore the switching value fault-signal that produces of this device is by the externally electric loop transmission of the terminal block in control box, for in the logic control of other electric control loop, with other electric control loop, there is good compatibility.
