Abstract
The utility model relates to an elevator band-type brake electricity blackout protection device. An electricity blackout protection relay (YB) in parallel connection is connected onto the circuit of band-type brake coil (L), and the relay (YB) is provided with two protecting diodes (D1, D2). The normally open contact (YB1) of the electricity blackout protection relay (YB) is connected onto the PC circuit. Each elevator is provided with feedback signal of the band-type brake relay; the elevator can stop working quickly if the control microcomputer does not receive the band-type brake feedback signal in the process of running, then the elevator is detected repeatedly, and can restart if the detection is normal. The elevator can not be started and is in protection state when the number of the failure, without band-type brake feedback signal, is up to a certain value during a certain time. Then the elevator is restarted only by providing with electricity again or clearing the failure. Thus abrasion is eliminated, and damage or burning of the brake shoe is avoided, therefore guaranteeing the safety of passengers and elevator devices.
Description
(1) technical field:
The utility model relates to elevator band-type brake loss protecting device.
(2) background technology:
Existing elevator does not all have the function of band-type brake loss protecting; when band-type brake is not opened owing to dead electricity; when mill band-type brake fault takes place; generally can only determine elevator band-type brake existing problems by indirect mode (hot protection, velocity feedback, overcurrent); tend to like this wear and tear; and after damaging or burning brake rubber block, brake rubber block and burn, elevator very easily take place to dash or pier at the bottom of serious accident out of control, lift facility and passenger safety are constituted higher threat.
(3) utility model content:
Technical problem to be solved in the utility model is at the problem that exists in the background technology, and a kind of elevator band-type brake loss protecting device is provided.
The invention for solving the technical problem can reach by following technical solution: loss protecting relay in parallel on the circuit of band-type brake coil connects two protection diodes on this relay; On the PC circuit, connect the open contact of loss protecting relay.
In such scheme, every elevator all has the feedback signal of band-type brake relay, when elevator in when operation, if the control microcomputer does not receive the band-type brake feedback signal, elevator will stop ladder at once, and detects again, as detects normally and will restart.Within a certain period of time, when the number of stoppages that no band-type brake feedback signal takes place ran up to certain value, elevator just can not restarted, and enters guard mode.Have only and send electricity again or remove fault, elevator just can restart.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: every elevator all has the feedback signal of band-type brake relay, when elevator in when operation, if the control microcomputer does not receive the band-type brake feedback signal, elevator will stop ladder at once, and detect again, as detect normally and will restart.Within a certain period of time, when the number of stoppages that no band-type brake feedback signal takes place ran up to certain value, elevator just can not restarted, and enters guard mode.Have only and send electricity again or remove fault, elevator just can restart.So just, can eliminate wearing and tearing, thereby avoid damaging or burning brake rubber block, lift facility and passenger safety are protected.
(4) description of drawings:
Accompanying drawing 1 band-type brake protective circuit figure;
Accompanying drawing 2 is the band-type brake protection feedback principle figure of loss protecting relay YB open contact YB1 in the map interlinking 1.
(5) specific embodiment:
Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:
In conjunction with shown in Figure 2, loss protecting relay YB in parallel on the circuit of band-type brake coil L meets two protection diode (D on this relay YB by Fig. 1
1, D
2); On the PC circuit, meet the open contact YB of loss protecting relay YB
1
In such scheme, as can be known from Fig. 1, behind the MB coil losing electricity, not adhesive of YB, then among Fig. 2, PC does not receive feedback signal, and elevator can not the band-type brake operation.
Claims (1)
1, a kind of elevator band-type brake loss protecting device that relates to contains the open contact (MB that is connected to the band-type brake relay on the circuit of band-type brake coil (L)
3), be connected to the open contact (MB of band-type brake relay on the PC circuit
1, MB
2), it is characterized in that: loss protecting relay in parallel (YB) on the circuit of band-type brake coil (L) meets two protection diode (D on this relay (YB)
1, D
2); On the PC circuit, meet the open contact (YB of loss protecting relay (YB)
1).
