Description
Technical field
The utility model relates to a kind of crane in bridge type magnetic chuck power failure protector magnetic device, belongs to magnetic separation control technology field.
Background technology
Magnetic chuck is a kind of machine tool accessories product utilizing electromagnetic principle.During use, Inside coil energising produces magnetic force, contact is tightly held at the workpiece of panel surface by magnetic conduction panel, and during coil blackout, magnetic force disappears, and magnetic conduction panel demagnetizes, and workpiece departs from panel.In practical operation, driving handling magnetic chuck is often adopted to carry out Mobile material sucking blowing.Sucker crane is when hanging thing operation, often there is maintenance below, refers to hang, Yu Gang cuts the cross-operation such as personnel and vehicle, and the power supply sky of sucker rectifier cabinet opens occasional appearance tripping operation circut breaking, now just continue power supply by power failure protector magnetic cabinet, the workpiece maintained on sucker does not drop, so that scene withdrawn by commanding, vehicle etc. at short notice.Hoisting crane electromagnet power failure magnet keeper is the safe-guard system at work of electromagnet scene, it can carry out automatic charging to backup power (battery pack) while lifting electromagnet work, when electromagnet is in suction state, if when meeting logical grid power blackout or other faults, the in-put of spare power supply that can automatically switch is powered, ensure that the material that electromagnet picks up can not fall, thus ensure the safety of operation field personnel and miscellaneous equipment.
The components and parts such as magnetic chuck, spring spool, cable and cable connector of driving, by the impact of high temperature, electric conductivity dust and the factors such as operation, repair quality, often there will be over the ground or the phenomenon of phase fault.In suction material process, there are again personnel and vehicle cross-operation in ground.During operation when magnetic chuck rectifier cabinet break down by power failure protector magnetic cabinet power emergent maintenance time, if protect magnetic cabinet also because circuit, components and parts etc. occur over the ground or phase fault, be then difficult to Timeliness coverage process.Because power failure protector magnetic cabinet just uses under emergency conditions, repair and maintenance personnel seldom get on when equipment is no problem inspection at ordinary times, if power failure protector magnetic cabinet goes wrong, are then difficult to Timeliness coverage.So when rectifier cabinet goes wrong and needs guarantor's magnetic cabinet to power, cannot work if protect magnetic cabinet fault, cause personnel and vehicle injures and deaths possibly, cause severe safety accident.
Utility model content
The purpose of this utility model is: for above-mentioned prior art Problems existing, a kind of crane in bridge type magnetic chuck power failure protector magnetic device is proposed, when protecting the fuse blows in magnetic device, turn off and inhale blowing switch, then annunciator is still reported to the police, and then remind staff's process in time, effectively avoid dangerous situation to occur.
In order to reach above object, the technical solution adopted in the utility model is as follows: a kind of crane in bridge type magnetic chuck power failure protector magnetic device, described guarantor's magnetic device comprises rectifier, power failure protector magnetic controller, current transformer, battery pack, piezoelectric detector, current probe, described rectifier and described power failure protector magnetic controller are electrically connected, described power failure protector magnetic controller and described current transformer, described battery pack, described piezoelectric detector, described current probe is electrically connected, described battery pack and circuit breaker, fuse, described power failure protector magnetic controller, contactless switch, relay forms trigger circuit, the contact switch of described relay is in parallel with contactless switch, the coil of described relay is in parallel with fuse.
Preferably, the mouth of described rectifier is connected with the input end of magnetic chuck coil.The two ends of described magnetic chuck coil are provided with volt meter.
The utility model beneficial effect is: when protecting the fuse blows in magnetic device, and turn off and inhale blowing switch, then annunciator is still reported to the police, and reminds staff's process.Compared to prior art, adopt this device can know the fault of protecting magnetic device in time, effectively avoid dangerous situation to occur.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is prior art circuits figure;
Fig. 2 is that the utility model embodiment one protects magnetic device circuit diagram.
Detailed description of the invention
Embodiment one
Fig. 1 is the circuit diagram of prior art, and Fig. 2 is this device circuit figure after improving, compared to Fig. 1 at a FU13 place parallel connection relay K A coil, at the contact switch of contactless switch KM place relay K A in parallel.As shown in Figure 2, a kind of crane in bridge type magnetic chuck power failure protector magnetic device, comprises rectifier, power failure protector magnetic controller TBK, current transformer TA2, battery pack GB, piezoelectric detector PV3, PV4, current probe PA3, PA4.Rectifier and power failure protector magnetic controller TBK are electrically connected, power failure protector magnetic controller TBK and current transformer TA2, battery pack GB, piezoelectric detector PV3, PV4, current probe PA3, PA4 are electrically connected, and battery pack GB and circuit breaker Q F3, fuse FU13, resistance R, electric whistle DD, contactless switch KM, fuse FU14 form trigger circuit.The contact switch of relay K A is in parallel with contactless switch KM, and the coil of relay K A is in parallel with fuse FU13.
Guarantor's magnetic principle of work of prior art is: the normal suction work of magnetic chuck, and during source of AC power-off unexpected because of other reason, now contactless switch KM closes automatically, and standby battery group starts power supply, and keep magnetic chuck suction state, electric whistle DD sends warning simultaneously.By operator's compartment buzzer, chaufeur of now driving a vehicle notifies that scene withdrawn by relevant operating personnel on production site and vehicle immediately, after personnel, vehicle are withdrawn and guaranteed safety, turn off and inhale blowing switch blowing, at this moment electric whistle DD also no longer reports to the police.If now occur, above situation needs use protects magnetic device and powers, and protect magnetic device also occur simultaneously alternate, to earth fault time, just cannot carry out guarantor's magnetic to magnetic chuck, may danger be caused thus.
The principle of work of the present embodiment is: when the normal suction of magnetic chuck works, if short circuit phenomenon appears in cable, spring spool and cable connector etc., and protect magnetic device and occur to protect magnetic action, electric whistle DD sends warning.If once just separately, fuse FU13 can not fuse in the components and parts short circuits such as cable, now turn off after inhaling blowing switch, electric whistle DD no longer reports to the police.If the short circuit phenomenon such as cable and components and parts still exists, then fuse FU13 can fuse, at this moment turn off and inhale blowing switch, the contact switch of relay K A closes, electric whistle DD still continues to report to the police, its signal sent can remind driving chaufeur to report process to the relevant personnel very first time, effectively avoids the generation of Peril Incident.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
