Abstract
A machine room-free elevator electric brake loosening device comprises a brake power supply box; a UPS (uninterrupted power supply) is arranged at the outer part of a brake control cabinet; a brake loosening switch and a brake loosening button are arranged between the UPS and the brake power supply box; a contactor is arranged on a braking loop for cutting off the power of an external power grid of the brake power supply box during electric brake loosening operation; the contactor is connected with the UPS for supplying power for the brake power supply box and a brake coil. The machine room-free elevator electric brake loosening device is simple in structure, convenient to operate and low in cost.
Description
Technical field
The utility model relates to a kind of elevator control gear, particularly a kind of electric brake releasing device of elevator without machine room.
Background technology
Elevator internal contracting brake is in static and motor, to prevent elevator mobile electromechanical device again when lift car under power failure state.In conventional lift, when the elevator band-type brake that breaks down, do the used time, need band-type brake be opened by manpower, make elevator toward the operation of load-carrying direction, thereby trapped personnel is emitted.Development along with modem elevator technology, energy-saving and environmental protection and joint space-efficient permanent-magnet synchronous machine-roomless lift are more and more subject to client's favor, but because machine-roomless lift is compact to design, space is little, convenient unlike having machine room elevator in operation, grid power blackout or other in emergency circumstances can not promptly be emitted trapped personnel by the manual band-type brake that unclamps as having machine room elevator outside.
Utility model content
In order to solve in prior art, machine-roomless lift can not be as having machine room elevator manual technical matters of unclamping band-type brake, the purpose of this utility model is to provide a kind of electric brake releasing device of elevator without machine room, this device has UPS in band-type brake control housing outer setting, when appearring in elevator in operational process, unforeseen circumstances band-type brake does the used time, UPS powers to band-type brake power pack by declutch switch and the button that declutches, thereby realize, declutches.
To achieve these goals, the utility model has adopted following technical scheme:
Electric brake releasing device of elevator without machine room, comprises band-type brake power pack, in band-type brake control housing outer setting, has UPS, is provided with declutch switch and the button that declutches between UPS and band-type brake power pack;
At brake circuit, be provided with contactless switch, for the electronic external power grid power supply of cutting off band-type brake power pack while opening a sluice gate to operate, and connect UPS and power to band-type brake power pack and band-type brake coil.
The beneficial effects of the utility model are:
Electric brake releasing device of elevator without machine room of the present utility model has UPS in band-type brake control housing outer setting, when unforeseen circumstances band-type brake appears in elevator in operational process, does the used time, and UPS powers to band-type brake power pack by declutch switch and the button that declutches, thereby realize, declutches.This apparatus structure is simple, easy to operate, and cost is low.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further details.
As shown in Figure 1, electric brake releasing device of elevator without machine room of the present utility model, comprises band-type brake power pack, in band-type brake control housing outer setting, has UPS, is provided with declutch switch and the button that declutches between UPS and band-type brake power pack; At brake circuit, be provided with contactless switch, for the electronic external power grid power supply of cutting off band-type brake power pack while opening a sluice gate to operate, and connect UPS and power to band-type brake power pack and band-type brake coil.Because band-type brake power pack can be adjusted output voltage grade, as DC200V or DC110V, therefore electric brake releasing device of elevator without machine room of the present utility model does not need to increase in addition voltage transformer, simple in structure.
In running process of elevator, when external power grid has a power failure or has other emergency situations, band-type brake effect, elevator stops.In this case, first need to press the switch that declutches, then press the button that declutches, UPS connects, and power supply is to band-type brake power pack and band-type brake coil.Traction machine brake obtains after electric and opens, and after this elevator can slowly move to the large side of weight.In this process, by band-type brake control housing observation window, check the flat bed mark of elevator, when elevator runs to after level position, unclamp the button that declutches, and recover to declutch switch, cut off ups power, band-type brake effect, elevator stops, and finally elevator door is opened and emitted trapped personnel.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
