Embodiment
The technical solution of the utility model is further illustrated below in conjunction with specific embodiment.
A kind of equipment bimanualness safety system involved by the utility model comprises start button SB1, start button SB2, reset button SB3, change over switch SB4, indicator light L, buzzer P, very first time relay, second time relay, auxiliary relay and mains switch QS; As shown in Figure 1, described start button SB1, start button SB2, reset button SB3, change over switch SB4, indicator light L, buzzer P, mains switch QS are arranged on electronic-control box 1 outer surface, it is inner that very first time relay, second time relay, auxiliary relay are encapsulated in electronic-control box 1, and described electronic-control box 1 lower end is provided with support 2.
Start button SB1 comprises normally opened contact SB1.1 and normally-closed contact SB1.2,
Start button SB2 comprises normally opened contact SB2.1 and normally-closed contact SB2.2,
Reset button SB3 comprises normally-closed contact SB3.1,
Change over switch SB4 comprises normally opened contact SB4.1 and normally-closed contact SB4.2,
Very first time relay comprises normally-closed contact KT1.1 and coil KT1,
Second time relay comprises normally-closed contact KT2.1, normally opened contact KT2.2 and coil KT2,
Auxiliary relay comprises normally opened contact KA1.1 and coil KA;
Described equipment bimanualness safety system comprises double startup self-lock of button/crawl loop, abnormal alarm loop and system mode instruction loop, arrange change over switch SB4 in double startup self-lock of button/crawl loop, the function being realized self-locking/crawl by change over switch SB4 is switched.
As shown in Figure 2, the circuit connecting relation of described equipment bimanualness safety system is: QS, SB1.1, SB2.1, KT2.1, KT1.1, KA are in series into loop, and after KA1.1, SB4.2, SB3.1 series connection, be connected in parallel on the two ends of SB1.1 and SB2.1, and be connected in parallel on the two ends of KA after SB4.1, KT1 series connection; Double startup self-lock of button/crawl loop is connected and composed by above circuit;
QS, SB1.1, SB2.2, SB3.1, KT2 are in series into loop, and SB2.1 and SB1.1 is in parallel, and SB1.2 and SB2.2 is in parallel, and buzzer P and KT2 is in parallel, and KT2.2 is connected in parallel on the two ends of SB1.1 and SB2.2; Abnormal alarm loop is connected and composed by above circuit;
QS, KT2.1, L are connected into loop, construction system state instruction loop.
Below the circuit operation method of the utility model equipment bimanualness safety system:
After closed electrical source switch QS, both hands are started by press button SB1 and SB2 simultaneously, the normally opened contact SB2.1 of normally opened contact SB1.1 and SB2 of SB1 is closed simultaneously, at this moment electric current makes the coil KA of auxiliary relay obtain electric through the normally-closed contact KT2.1 of SB1.1, SB2.1, second time relay and the normally-closed contact KT1.1 of very first time relay, KA obtains the electric normally opened contact KA1.1 of auxiliary relay that makes and closes, thus making KA1.1, SB4.2, SB3.1 line conduction be in parallel with SB1.1 and SB2.1 complete self-locking, control appliance reaches " operating continuously ".
Press reset button SB3 during stopping, the normally-closed contact SB3.1 of SB3 is disconnected, thus makes the coil KA dead electricity of auxiliary relay, KA resets and the normally opened contact KA1.1 of auxiliary relay is disconnected), control appliance shuts down.
When controlled equipment need carry out " crawl " operate time, rotate change over switch SB4, the normally-closed contact SB4.2 of the change over switch SB4 in the circuit that is now in parallel with SB1.1 and SB2.1 (i.e. KA1.1, SB4.2, SB3.1 form circuit) is in off-state, at this moment latching circuit is disconnected, cannot self-locking during auxiliary relay action; When SB1.1 and SB2.1 is simultaneously closed, electric current flows through the running of SB1.1, SB2.1, KT2.1, KT1.1, SB4.1 (SB4.1 is in closure state) control appliance, the coil KT1 energized action trigger timing of very first time relay simultaneously, when after the delay time exceeding very first time relay setting, the normally-closed contact KT1.1 of very first time relay disconnects, control appliance shuts down, thus reaches the object of both hands crawl.By adjusting the delay time of very first time relay, can time of control appliance crawl.
When system is by abnormal operation, namely both hands do not have at the appointed time started by press button SB1 and SB2 simultaneously, as only started by press button SB1, SB1.1 in abnormal alarm loop, SB2.2 conducting, the coil KT2 energized action trigger timing of second time relay, when after the time exceeding the second time relay setting, the normally opened contact KT2.2 of second time relay is closed forms self-locking, buzzer P conducting in abnormal alarm loop is given the alarm, normally-closed contact KT2.1 disconnects and makes system mode indicate " system is normal " indicator light L in loop to extinguish simultaneously, normally-closed contact KT2.1 disconnects and double startup self-lock of button loop and double startup button crawl loop is disconnected simultaneously.In like manner, as only started by press button SB2, SB2.1 in abnormal alarm loop, SB1.2 conducting, the coil KT2 energized action trigger timing of second time relay, when after the time exceeding the second time relay setting, the normally opened contact KT2.2 of second time relay is closed forms self-locking, buzzer P conducting in abnormal alarm loop is given the alarm, normally-closed contact KT2.1 disconnects and makes system mode indicate " system is normal " indicator light L in loop to extinguish simultaneously, normally-closed contact KT2.1 disconnects and double startup self-lock of button loop and double startup button crawl loop is disconnected simultaneously.
Above exemplary description is done to the utility model; should be noted that; when not departing from core of the present utility model, any simple distortion, amendment or other those skilled in the art can not spend the equivalent replacement of creative work all to fall into protection range of the present utility model.
