Embodiment 2
When retarder is worm reducer, Fig. 1 a and 1b is depicted as band brake worm reduction gear.
Building hoist band brake reductor, it comprises retarder and magnet stopper, retarder and magnet stopper are connected to one, worm reducer input shaft 14 overcoat has motor tie-plate 15, motor tie-plate 15 is connected with motor, oil sealing 12 is provided with outside worm reducer 13 input shaft, magnet stopper comprises electromagnet 5, armature 7, fixing brake disc 9, brake disc 8 and retarding spring 4, fixing brake disc 9 is fixed on drg tie-plate 11, brake disc 8 is between armature 7 and fixing brake disc 9, the hexagonal that brake disc 8 overlaps 10 with hexagonal engages, armature 7 and electromagnet 5 are by backstopping device 6, bonnet 1, a suitable gap set up by adjusting sleeve 3 and retarding spring 4, manual releasing handle 2 is arranged on bonnet 1 back and is fixed on electromagnet 5 through bonnet 1.
In above-described embodiment, with the reductor of drg, exactly between motor and retarder or worm reducer speed end afterbody add one group there is the spring pressurization magnet stopper of safety protection function or common spring pressurization magnet stopper.And motor carries spring pressurization magnet stopper is traditional band gap automatic tracking and compensating spring pressurization magnet stopper or the spring pressurization magnet stopper with safety protection function.
The above-mentioned said spring pressurization electromagnetism magnet stopper with safety protection function is by the magnet stopper of DC power supply; Above-mentioned electromagnet is the interior special soft-magnetic material framing member having one group of magnet coil; Above-mentioned said brake strip, by corrosion-resistant steel or aluminum alloy body and special friction material bond form there is the peculiar part that great friction coefficient and low specific wearability can transmit design torque.
Above-mentioned fixing brake disc is fixed on brake strip side, actionless friction pair part, armature is the friction pair part be arranged between electromagnet and brake strip that floats, and electromagnet is provided with one group or two groups of micro-switch mechano-electronic signal conversion element (micro-switch) of setting up with armature and contacting distance.
In the utility model, spring pressurization magnet stopper has and is different from the unexistent performance of conventional belt gap automatic tracking and compensating (common) magnet stopper.Its principle is: spring pressurization magnet stopper has two friction surfaces, when magnet coil power-off, the masterpiece that spring produces is used on armature, is tightly clipped between armature and fixing brake disc by the friction brake disk of half a coupler driven rotary, thus produces lock torque.Now, a gap can be produced between armature and electromagnet, when needs loosen the brake, magnet coil connects direct current (DC), and the magnetic field suction armature produced moves to electromagnet, and drives micro-switch striker corresponding actions, send automatically controlled signal, Compress Spring when armature moves, now friction brake disk is released, brake release.
As motor electromagnetic brake malfunctions, the spring pressurization magnet stopper of band safety protection function still effectively can take on braking role, avoids gliding, falling and safety misadventure.
When magnet coil occur connect fault, armature fails to move to electromagnet, and the striker of micro-switch is not operating, does not send automatically controlled signal, and motor can not be activated, and automatically controlled light or (with) buzzer phone response under, send failure message.By the embodiment of this function, solve the hidden danger of building hoist brake fault well, reduce transmission device wear-out failure, aggravation failure is frequent.
By automatically controlled setting, certain delays time to control is carried out to the action of primary auxiliary brake (magnet stopper of motor self) and two stage braking device (the spring pressurization magnet stopper namely with safety protection function or common spring pressurization magnet stopper), what transmission device obtained that control system sends start or stop specify instantaneous, overcome system inertia and braking force accelerates to design speed from zero-speed is instantaneous or reduces to the process of zero-speed from design speed is instantaneous, adding shock damping action thus making to add (subtracting) speed controls at reasonable interval, effectively eliminate the brute force attack opening braking, by the embodiment of this function, efficiently solve building hoist and open braking stationarity, affect the problems that occupant is comfortable.
