The electromagnet of both sides constitutes double electromagnet, in the middle of latching device is positioned at, forms this center lock button electromagnetic switch.
Wherein, electromagnet can be sucked type electromagnet or cylindricality electromagnet or push-pull electromagnet or towed electromagnet etc.
Latching device has the snap close and the lock pin of mutual correspondence, snap close to be arranged on the moving crane span structure, and lock pin is arranged on the dropout armature, and dropout armature is arranged on the bearing pin, is provided with stage clip between dropout armature and the base, the corresponding release magnet that is provided with dropout armature.
Equally, release magnet also can be sucked type electromagnet, cylindricality electromagnet, push-pull electromagnet or towed electromagnet etc., can and moving crane span structure and base between electromagnet identical or different, not simultaneously, form the hybrid combining behaviour in service.
Release magnet can be horizontally disposed with, and is fixed on the corresponding snap close base that is provided with.Release magnet also can vertically be provided with, and sets up the turnover pressing plate on the dropout armature, and the turnover pressing plate is corresponding with release magnet, and release magnet is fixed on the snap close base.
Base and snap close base can be fixed as one.
The present invention compared with prior art has following beneficial effect:
The present invention is simple and compact for structure, rationally, sucked type electromagnet or cylindricality electromagnet or push-pull electromagnet or towed electromagnet have been selected on the one hand for use, dwindled volume greatly, improved performance, on the other hand latching device is installed in the middle part between moving crane span structure and the base, form center lock button structure, the pressure that has guaranteed three contacts is even, avoided the inclined to one side phase problem of side snap close (three contact pressure differences), switch performance is improved greatly, and because switching mechanism combines mechanical caging, working stability, dependable performance, the operating state that has thoroughly solved pure electromagnetic switch be subjected to voltage ripple of power network influence existence defective (the voltage height easily burn solenoid; Voltage is low easily to be kept incessantly, also can cause burning contact because of the contact pressure reduction simultaneously).Be applied in the control of supply line or electric equipment, as, can directly be applied in motor protecter and the earth leakage protective device, make motor protecter and earth leakage protective device improve upgrading.
