Embodiment
To combine accompanying drawing that the utility model is described further below.
Like Fig. 1, Fig. 2 and shown in Figure 3; The utility model comprises switching-over control section and locking control section; The switching-over part comprises reversing handle 1, reversing switch fanning strip 2 and isolates reversing switch 3 that latch portion comprises latch buttons 4, locking location-plate 5 and control auxilliary point 6 that said reversing handle 1 is fixedly connected with fanning strip 2; Reversing handle 1 is connected with isolation reversing switch 3; Latch buttons 4 is fixedly connected with locking location-plate 5, and latch buttons 4 connects the auxilliary point 6 of control, and positioning stud 7 is fixed on cabinet door 8 outsides; Latch buttons 4 is electrically connected PLC module and power supply, isolates reversing switch 3 and connects discharge resistance; Said reversing handle 1 is fixedly connected by welding with fanning strip 2; Said reversing handle 1 is connected with isolation reversing switch 3 through connecting bolt; Said latch buttons 4 is fixedly connected by welding with locking location-plate 5; Be that morpheme through reversing switch fanning strip 2 and locking location-plate 5 is connected between said switching-over control section and the latch portion.
The mechanically actuated operation process of the utility model: make locking location-plate 5 break away from reversing switch fanning strip 2 through depressing latch buttons 4, the turn reversing handle 1 then, and after the adjustment angle, just removable positioning stud 7 reaches the purpose at open and close Qianmen.
Electric loop is connected process: press the button GH1, it often opens auxilliary point 3., 4. closed or normally closed auxilliary point 1., 2. break off sends signal for last level power supply, also the switching value signal is input in the PLC module.To isolate reversing switch GK1 again and rotate to certain angle, then the contact of GK1 is 1. ~ 6. closed, and electric loop is connected.
Electric loop breaks off process: press the button GH1, it often opens auxilliary point 3., 4. closed or normally closed auxilliary point 1., 2. break off sends signal for last level power supply, also the switching value signal is input in the PLC module.To isolate reversing switch GK1 again and rotate to initial angle, then 1. ~ 6. the contact of GK1 is broken off, and electric loop breaks off.
The course of work of this locking device is divided into two states:
System is by power-up state during to off-position: press latch buttons 4 (GH1), it often opens auxilliary point 3., 4. closed or normally closed auxilliary point 1., 2. break off sends power-off signal for last level power supply, also the switching value signal is input in the PLC module.At this moment locking location-plate 5 breaks away from reversing switch fanning strip 2, will isolate reversing switch 3 (GK1) again and rotate to certain angle, be i.e. location hole aligned double-screw bolt 7 on the reversing handle 1; This moment, the contact of GK1 was 1. ~ 6. closed, and electric loop CT+, CT0, CT-connected discharge resistance R31, R32, through several seconds; System discharge finishes; Turn 7 positioning studs are opened cabinet door 8, can guarantee safety.
System is by off-position during to power-up state: press latch buttons 4 (GH1), it often opens auxilliary point 3., 4. closed or normally closed auxilliary point 1., 2. break off sends power on signal for last level power supply, also the switching value signal is input in the PLC module.At this moment locking location-plate 5 breaks away from reversing switch fanning strip 2, will isolate reversing switch 3 (GK1) again and rotate to initial angle, and 1. ~ 6. the contact of GK1 is broken off, and electric loop CT+, CT0, CT-disconnect discharge resistance R31, R32, can the cabinet door be closed.Be not screwed into the exact position if in this process, isolate reversing switch 3,1. ~ 6. the contact of GK1 then can not be broken off, and can't power on this moment, explains that cabinet Men Wei fastens.
In system's charging operation process, 1. ~ 6. the contact of GK1 is in off-state all the time.
