in aforementioned Emergency power supply unit, described power-switching circuit ZH comprises relay J 1 and relay J 2; In relay J 1, be provided with coil, normally opened contact, normally-closed contact and common port; The coil of relay J 1 is connected with charger CD through K switch 2, the normally opened contact of relay J 1 is connected with the coil of relay J 3, the normally-closed contact of relay J 1 is connected with normally opened contact one end with the coil of relay J 2, and the normally opened contact other end of relay J 2 is connected with the coil of relay J 4.
in aforementioned Emergency power supply unit, described load FZ front end is provided with fuse RD.
in aforementioned Emergency power supply unit, the illumination that described load FZ is operation site and working electromagnet valve.
compared with prior art, the utility model has increased by a group storage battery E in the electric power system of electronic steel grasping machine, in the main controller ZK of electronic steel grasping machine, increased a set of charger CD simultaneously, when supply line is normal, charger CD is storage battery E charging, after storage battery E is saturated, main controller ZK controls charger CD and automatically stops storage battery E to charge; When external power source has a power failure, can be switched to by the diverter switch in driver's cabin storage battery E and power, and disconnect being connected of storage battery and main electrical control cubicles, the electric current that prevents storage battery is become owner of electrical control cubicles and is damaged electric component.The utility model is due to the supply power mode of use storage battery E as stand-by power supply, the supply that realizes emergency power supply that can be quick and easy.Have simple in structurely, install, easy to operate feature, can eliminate the potential safety hazard that unexpected power failure causes.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
Embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
an Emergency power supply unit for electronic steel grasping machine, as shown in Figure 1.Comprise main controller ZK, in main controller ZK, be provided with charger CD and voltage regulator TY; Charger CD is connected with storage battery E through K switch 1; Voltage regulator TY is connected with load FZ through the normally opened contact of relay J 4; Charger CD is connected with load FZ through the normally opened contact of relay J 3; The coil of relay J 3 and relay J 4 is connected with power-switching circuit ZH.Power-switching circuit ZH comprises relay J 1 and relay J 2; In relay J 1, be provided with coil, normally opened contact, normally-closed contact and common port; The coil of relay J 1 is connected with charger CD through K switch 2, the normally opened contact of relay J 1 is connected with the coil of relay J 3, the normally-closed contact of relay J 1 is connected with normally opened contact one end with the coil of relay J 2, and the normally opened contact other end of relay J 2 is connected with the coil of relay J 4.Described load FZ front end is provided with fuse RD.Load FZ is illumination and the working electromagnet valve of operation site.
the course of work of the present utility model and principle
as shown in Figure 1, the K switch 2 in Fig. 1 is transfer switches, during disconnection, by the voltage regulator TY in main controller ZK, is load supplying, when closed, by storage battery E, is load supplying.When interchange 380V external power is normal, K switch 2 is in off-state, now, the output of charger CD is the coil power supply of relay J 2 through the normally-closed contact of relay J 1, the normally opened contact of relay J 2 is closure state, and the coil of relay J 4 obtains electric, and the normally opened contact of relay J 4 is closed.Voltage regulator TY output 24V direct voltage in main controller ZK is each electromagnetically operated valve and illumination (electromagnetically operated valve and illumination are loads of the present invention) normal power supply on electronic steel grasping machine by the normally opened contact of relay J 4.The charger CD output 27～28V direct voltage in main controller ZK simultaneously, charges for storage battery E by K switch 1, and K switch 1 is hand switch, is in on-state under normal circumstances, does not generally disconnect.When main controller ZK power supply is normal, can be automatically to storage battery E charging, after storage battery E is saturated, main controller ZK can stop storage battery E to charge automatically.After external power has a power failure, the operating personnel of electronic steel grasping machine can open K switch 2(, and now K switch 1 should be in on-state), the electric current of storage battery E is by the coil of relay J 1, often opening and normally-closed contact generation redirect of relay J 1, storage battery E electric current is the coil power supply of relay J 3 through relay J 1 normally opened contact, make closed connection of normally opened contact of relay J 3, making the electric current of storage battery E is load FZ power supply through normally opened contact and the fuse of relay J 3.In closed connection of normally opened contact of relay J 3, the normally-closed contact redirect of relay J 3 is off-state, make the coil blackout of relay J 2, the normally opened contact of relay J 2 is in off-state, make the coil blackout of relay J 4, the normally opened contact of relay J 4 is in off-state, and cutting-off pressure-regulating device TY is connected with load, prevents that the electric current of storage battery E from entering main controller damage electric component.
