Abstract
The utility model discloses an elevator safety band-type brake loop which comprises a sub circuit formed by connecting in series a door lock relay (1), a band-type brake relay (2), a current-limiting resistor (3) and the input end of a photoelectric coupler (4) in sequence. The output end of the photoelectric coupler (4) is connected with the input end of a voltage-regulating controller (5), and the output end of the voltage-regulating controller (5) is connected with a sub circuit formed by connecting in series an operation contactor (6) and a brake coil (7). According to the elevator safety band-type brake loop, the brake coil and a contact of the operation contactor are separated from the band-type brake loop and are connected in series to the output end of the voltage-regulating controller, and the contact of the operation contactor can not be bonded. The voltage-regulating controller is in a standby state all the time, frequent cold boot of the voltage-regulating controller is avoided, and stability and reliability of the voltage-regulating controller are improved.
Description
Technical field
The utility model relates to a kind of elevator internal contracting brake loop, particularly a kind of elevator safety brake loop.
Background technology
Along with the development of science and technology, elevator technology makes rapid progress.Therefore but drg is as a very important safety component of elevator, and its brake loop is unalterable so far, and in today that other class safety misadventures of elevator significantly reduce, the fault and the shared ratio of accident that are caused by drg progressively rise.
There is following defect in existing elevator brake brake loop: the operation contacts of contactor of (1) brake loop easily sticks together, and causes the drg can't band-type brake; (2) voltage regulator controllers in brake loop, is in the state of frequent cold start-up all the time, causes the stability of voltage regulator controllers and reliability low.
The utility model content
The purpose of this utility model is, a kind of elevator safety brake loop is provided.The operation contacts of contactor that the utility model has overcome existing brake loop easily sticks together and causes defect that drg can't band-type brake and voltage regulator controllers to be in all the time the state of frequent cold start-up and cause stability and the low defect of reliability of voltage regulator controllers.
The technical solution of the utility model: the elevator safety brake loop comprises successively the branch road that the input end by door lock relay, band-type brake relay, current-limiting resistance and photoelectrical coupler is in series; The mouth of described photoelectrical coupler is connected with the input end of voltage regulator controllers, and the mouth of voltage regulator controllers is connected with the branch road that is connected with brake coil by the operation contactless switch.
In aforesaid elevator safety brake loop, described voltage regulator controllers is by ac power supply.
Compared with prior art, the utility model is by brake coil and operation contacts of contactor are separated from brake loop, and the mouth of voltage regulator controllers is received in their series connection, and the operation contacts of contactor can not stick together; Voltage regulator controllers of the present utility model is in readiness for action all the time, has avoided voltage regulator controllers cold start-up continually, has improved stability and the reliability of voltage regulator controllers.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-door lock relay, 2-band-type brake relay, the 3-current-limiting resistance, the 4-photoelectrical coupler, the 5-voltage regulator controllers, 6-moves contactless switch, 7-brake coil, 8-source of AC.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.The elevator safety brake loop, as shown in Figure 1, comprise successively the branch road that the input end by door lock relay 1, band-type brake relay 2, current-limiting resistance 3 and photoelectrical coupler 4 is in series; The mouth of described photoelectrical coupler 4 is connected with the input end of voltage regulator controllers 5, the mouth of voltage regulator controllers 5 with are connected by operation contactless switch 6 branch road that is in series with brake coil and are connected.Described voltage regulator controllers 5 is by source of AC 8 power supplies (effect of source of AC 8 is: make voltage regulator controllers 5 be in readiness for action).
The process that declutches of elevator brake: band-type brake relay 2 closures, the mouth output low level of photoelectrical coupler 4, be subjected to this low level control, and voltage regulator controllers 5 is sent driving voltage to brake coil 7, drives drg and declutches.
The band-type brake process of elevator brake: door lock relay 1 or band-type brake relay 2 disconnect, and the mouth output high level of photoelectrical coupler 4, controlled by this high level, and the output voltage of voltage regulator controllers 5 is zero, drives the drg band-type brake.
Claims (2)
1. elevator safety brake loop is characterized in that: comprise successively the branch road that the input end by door lock relay (1), band-type brake relay (2), current-limiting resistance (3) and photoelectrical coupler (4) is in series; The mouth of described photoelectrical coupler (4) is connected with the input end of voltage regulator controllers (5), the mouth of voltage regulator controllers (5) be connected 7 by operation contactless switch (6) with brake coil) branch road that is in series is connected.
2. elevator safety brake loop according to claim 1, it is characterized in that: described voltage regulator controllers (5) is powered by source of AC (8).
