The specific embodiment
The utility model has been realized the integrated output with low-voltage direct 24V power supply of band-type brake power supply and elevator, and built-in short circuit, over-current protecting unit, and effectively cost-cutting is saved installing space, and the raising output voltage stability eliminates safe hidden trouble.
As shown in Figure 2, be the scheme drawing of the auxiliary dc driver embodiment of elevator of the present utility model.The auxiliary dc driver of this elevator comprises the rectifying circuit 32 that is used for source of AC is converted to high voltage direct current output, the second source circuit 40 that is used to export first power circuit 41 of low-voltage DC and is used to export the band-type brake voltage signal, wherein the input end of first power circuit 41 and second source circuit 42 is connected respectively to the mouth of rectifying circuit 32, first power circuit 41 comprises first mouth 42 that is used for connecting the apparatus for controlling elevator weak current part, and second source circuit 40 comprises second mouth 39 that connects the brake sticking brake device and the external trigger circuit 33 that connects the band-type brake signal control terminal 39 of apparatus for controlling elevator.
Rectifying circuit 32 is used for the alternating-current voltage/AC voltage of input is converted to direct current output, as the input end of first power circuit 41 and second source circuit 40.The output signal break-make of external trigger circuit 33 control second source circuit 40, when outer triggering signal is effective, band-type brake signal control terminal 39 output actv. band-type brake signals.
The voltage output end of BUCK circuit 36 links to each other with automatic reduction voltage circuit 37, electric voltage observation circuit 38, and reduction voltage circuit 37 is opened the voltage of keeping that keeps required according to the outgoing current variation control band-type brake of BUCK circuit 36 automatically.Electric voltage observation circuit 38 is the size of monitoring output voltage in real time, when being changed by line voltage, output voltage signal feeds back to the BUCK circuit immediately, can effectively avoid exporting the influence that the band-type brake power supply signal is subject to voltage ripple of power network, keep output voltage signal constant.
It is 55%～81% of national regulation that voltage range is kept in the output of restricted voltage-regulating circuit 35 major control second source circuit 40, guarantee that band-type brake is in normal working at any time, avoid elevator towing machine in normal course of operation to be taken place by the phenomenon of locking suddenly, eliminate safe hidden trouble.
In above-mentioned direct current auxiliary actuator, also comprise overcurrent, short-circuit protection unit, can not influence each other between the output signal that guarantees first, second power circuit, can guarantee when promptly arbitrary output overcurrent or short circuit that another road output signal is normal.
As shown in Figure 3, the utility model also offers a kind of elevator drive control setup, and this elevator drive control setup comprises elevator direct current auxiliary actuator and apparatus for controlling elevator as shown in Figure 3.
If safety return circuit control terminal Y, the M of apparatus for controlling elevator are effective, then the relay K closure makes contactless coil BYJ action, the contactless coil BYJ adhesive on the band-type brake power supply output signal loop of control direct current auxiliary actuator.At this moment, when band-type brake signal control terminal Y2, the M2 of apparatus for controlling elevator export when effective, above-mentioned dc driver the first terminal group Y1, M1 are effective, peripheral trigger circuit action, control second source circuit produces required 110V and/or the 220V band-type brake power supply of band-type brake, finishes the process of control band-type brake this moment.Because during the output of band-type brake power supply signal, outgoing current is the process that an oblique line rises, and can relax the action of brake sticking brake device, vibrations of sending when avoiding abrupt release and adhesive and noise, the service life of guaranteeing motor and brake sticking brake device.In addition, the band-type brake power supply is exported when effective, and the contactless coil BYJ on the band-type brake power supply output signal loop has been in attracting state, has avoided electric arcing, thereby but actv. is avoided contactless switch adhesion hidden danger.After this, the brake sticking brake device will be operated in and keep under the voltage and the maintenance release position.
When the band-type brake signal control terminal Y2 of apparatus for controlling elevator, M2 no-output, the first terminal group Y1, M1 can not receive actv. band-type brake power supply and produce signal, the second source circuit is not worked, and the band-type brake voltage of output slowly reduces to 0 by keeping voltage in 0.6s-0.8s.Even safety return circuit conducting this moment, contactless coil BYJ adhesive, the output band-type brake power supply signal of power panel still is 0, can more or not have the hidden danger of contactless switch adhesion to the effect of band-type brake control contactor.
Because band-type brake is required keeps voltage range and is strict controlled in 55%～81% scope that GB requires, in case setting, the user keeps voltage swing, the output voltage monitoring function that cooperates the second source circuit, that can guarantee to export keeps voltage and can not keep constant with voltage ripple of power network, eliminates at elevator towing machine in service suddenly by the potential safety hazard of locking.
The auxiliary dc driver of above-mentioned elevator can directly apply to apparatus for controlling elevator, replaces low-voltage power supply module and band-type brake supply module in the former apparatus for controlling elevator, thereby provides cost savings and volume.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
