Abstract
The utility model discloses an elevator hauler band -type brake braking partial pressure control circuit, it includes: band -type brake partial pressure control circuit internal electric source, its negative pole connect in hauler band -type brake coil - ZQ binding post, the positive pole of this band -type brake partial pressure control circuit internal electric source has connected gradually resistance R1, resistance R2, resistance R3, relay K4 and diode D1, diode D1's negative pole connect in hauler band -type brake coil + ZQ binding post, wherein, resistance R1 connects in parallel has relay K1, and resistance R2 connects in parallel has relay K2, resistance R3 connects in parallel has relay K3. This control circuit meets the trouble scram vehicle -hour in can effectual solution elevator operation, and because of band -type brake coil voltage cuts off immediately, the band -type brake arm closes immediately, and the elevator stops immediately, because speed inertia causes the problem of casualties in the ladder.
Description
Technical field
This utility model relates to elevator technology field, especially relates to a kind of elevator traction machine brake sticking brake pressure control circuit.
Background technology
Having parts very crucial in elevator controlling, be then traction machine, wherein normally closed brake (being band-type brake) is one of vitals of composition traction machine.
At present, in elevator industry, when in running process of elevator in case of emergency, apparatus for controlling elevator can stop ladder immediately, way now is turned off band-type brake circuit, make band-type brake immediately with traction machine braked wheel with all strength CONTACT WITH FRICTION, elevator is caused to stop ladder immediately, but because elevator has certain speed in running, when band-type brake produces friction with traction machine braked wheel immediately with all strength, it will produce very big deceleration to elevator, and due to the effect of velocity inertia, personnel and article in ladder can still continue to run with according to present speed, now will certainly to producing in ladder to impact, once elevator jerk and when front ladder speed reaches more than 1.0m/s, then very easily there is personnel casualty accidents in ladder.
Utility model content
The purpose of this utility model is contemplated to solve the problems referred to above, a kind of elevator traction machine brake sticking brake pressure control circuit is provided, when it can solve to meet fault jerk car during elevator runs, because band-type brake coil voltage cuts off immediately, brake arm is closed immediately, elevator stops immediately, owing to velocity inertia causes the problem of casualties in ladder.
To achieve these goals, this utility model adopts the following technical scheme that
Elevator traction machine brake sticking brake pressure control circuit, comprising: band-type brake pressure control circuit internal electric source, its negative pole is connected to the-ZQ binding post of traction machine band-type brake coil, the positive pole of this band-type brake pressure control circuit internal electric source is connected with resistance R1, resistance R2, resistance R3, relay K 4 and diode D1 in turn, the negative pole of described diode D1 is connected to the+ZQ binding post of traction machine band-type brake coil, described resistance R1 is parallel with relay K 1, and resistance R2 is parallel with relay K 2, resistance R3 is parallel with relay K 3.
This invention is when elevator is in running, and because of non-security loop fault during jerk car, the way adopting band-type brake coil voltage dividing potential drop to control, the ascending elevator that realizes stops terraced method with the frictional force of traction machine brake disc to make brake arm.Adopting said method elevator is under non-security loop fault state during jerk car, produced frictional distance between brake arm and traction machine braking dish can be made elongated, thus reaching to increase the displacement of car when elevator emergency stops, reducing the deceleration of car when elevator emergency stops with this, this compares and the personal injury degree of personnel in ladder will be reduced much band-type brake locking immediately when occurring unusual failure in current elevator industry.
Accompanying drawing explanation
Fig. 1 is elevator traction machine brake sticking brake pressure control circuit figure.
Fig. 2 is the annexation figure of elevator traction machine brake sticking brake pressure control circuit and band-type brake coil control part, traction machine band-type brake coil.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with specific embodiment, this utility model is expanded on further.
Referring to Fig. 1, the figure shows elevator traction machine brake sticking brake pressure control circuit principle, include band-type brake pressure control circuit internal electric source, resistance R1 resistance R2, resistance R3, relay K 1, relay K 2, relay K 3, relay K 4, diode D1 in the figure.
Specifically, this utility model circuit is made up of band-type brake pressure control circuit internal electric source, resistance, diode level relay normally open contact, and the positive level of band-type brake pressure control circuit internal electric source and resistance R1 one end, normally opened some one end of relay K 1 electrically connect; The resistance R1 other end and normally opened some other end of relay K 1, resistance R2 one end, normally opened some one end electrical connection of relay K 2; The resistance R2 other end and normally opened some other end of relay K 2, resistance R3 one end, normally opened some one end electrical connection of relay K 3; The resistance R3 other end and normally opened some other end of relay K 3, normally opened some one end electrical connection of relay K 4; Normally opened some other end of relay K 4 and diode D1 positive electrical connect, and diode D1 negative electricity is connected to+ZQ binding post; Band-type brake pressure control circuit internal electric source negative electricity is connected to-ZQ binding post.
Fig. 2 is the annexation figure of elevator traction machine brake sticking brake pressure control circuit and band-type brake coil control part, traction machine band-type brake coil, and concrete connected mode is described above, is not repeated herein.
When elevator is in running, because of non-security loop fault during jerk car, band-type brake coil voltage is carried out dividing potential drop control, namely in regular hour section, by the mode of electric resistance partial pressure, supplying band-type brake coil by successively descending for voltage, until the voltage being added in coil two ends is zero, this circuit methods can make brake arm ascending with the frictional force of traction machine brake disc and be finally reached the purpose that elevator stops. Adopting said method elevator is under non-security loop fault state during non-normal stop; produced frictional distance between brake arm and traction machine braking dish can be increased; thus reach strengthen elevator emergency stop time car displacement, with this reduce elevator emergency stop time car deceleration to protect the personal safety of personnel in ladder.
The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme belonging to this utility model principle belongs to protection domain of the present utility model. For a person skilled in the art, the some improvement carried out under the premise without departing from principle of the present utility model, these improvement also should be regarded as protection domain of the present utility model.
