The control system comprises two groups of contracting brake circuit which are connected with the electromagnetic brake and connect by concatenation with each other, wherein a first contracting brake circuit is made up of a first protection diode and a first brake coil which are connected in parallel, a second contracting brake circuit comprises a second protection diode and a second brake coil which are connected in parallel, the structure is characterized in that a capacitance and a resistance are fixed in parallel connection on the both ends of the second brake coil, and a forward connection diode is connected in series on an input end of the circuitof the control system. The utility model has the advantages of decelerating the elevator and the escalator to stop at relatively-stationary speed.
Description
Technical field
The utility model relates to a kind of magnet stopper time-delay band-type brake control system, and it is used for the towing machine of elevator and escalator.
Background technology
Magnet stopper in existing elevator and the escalator towing machine is made up of two groups of band-type brake circuit, and the band-type brake circuit is formed in parallel by diode and restraining coil.When stopping the outage of ladder or external power supply, two groups of band-type brake circuit move simultaneously, elevator and escalator are decelerated to stop, but the lock torque of braking simultaneously owing to two groups of band-type brake circuit is bigger, therefore can produce very large acceleration/accel, occur the accident that personnel fall down easily.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of elevator that can make and is decelerated to the magnet stopper time-delay band-type brake control system of stopping ladder with relative pulsation-free speed with escalator.
The technical scheme in the invention for solving the above technical problem is: this control system comprises two groups of band-type brake circuit that link to each other with magnet stopper; two groups of band-type brake circuit are connected mutually; wherein the first band-type brake circuit is formed in parallel by the first protection diode and first restraining coil; the second band-type brake circuit comprises the second protection diode and second restraining coil in parallel; its constructional feature is also to be parallel with electric capacity and resistance at the two ends of described second restraining coil, and at the circuit input end of the control system forward bonded assembly diode of connecting.
Electric capacity described in the utility model is connected with resistance afterwards and the second restraining coil reverse parallel connection; The first protection diode and the second protection diode are reverse bonded assembly diode.
The utility model compared with prior art, have following beneficial effect: this system is tank circuit that is in series by electric capacity and resistance in parallel in one group of band-type brake circuit therein, like this when elevator and escalator stop ladder or external power supply outage, one group of band-type brake circuit normal brake application, another group is parallel with the band-type brake circuit delay braking of tank circuit, stop ladder thereby elevator is decelerated to relative pulsation-free speed with escalator, and can come the control lag time by the capacity of adjustment electric capacity and the resistance of resistance.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model.
The specific embodiment
Referring to Fig. 1, present embodiment is made up of the first band-type brake circuit I that links to each other with magnet stopper, the second band-type brake circuit I I and diode 1, and the first band-type brake circuit I is formed in parallel by the first protection diode 7 and first restraining coil 2; The second band-type brake circuit I I comprises the second protection diode 6 and second restraining coil 5 in parallel, and also is parallel with electric capacity 3 and resistance 4 at the two ends of second restraining coil 5, and electric capacity 3 is connected with resistance 4 afterwards and second restraining coil, 5 reverse parallel connections.The first band-type brake circuit I and second band-type brake circuit I I series connection, and at the circuit input end of the control system forward bonded assembly diode 1 of connecting.The first protection diode 7 and the second protection diode 6 are reverse bonded assembly diode.
During work, the effect of diode 1 mainly is to prevent that electric capacity 3 from partly turning back to electric energy in the electrical network in discharge process.
The effect of the first protection diode 7 and the second protection diode 6 is to cut off the power supply moment when restraining coil, and the coil two ends produce inverse electromotive force (being equivalent to electrical generator), by the first protection diode 7 and the second protection diode 6 this voltage is discharged.
The effect of the second band-type brake circuit I I is as tank circuit, when the 5 energising work of second restraining coil, power supply gives electric capacity 3 chargings, after down circuitry, the first band-type brake circuit I normal brake application, electric capacity 3 stored voltage then continue to be carried in second restraining coil, 5 two ends among the second band-type brake circuit I I, slowly discharge by second restraining coil 5, when second restraining coil, 5 both end voltage less than after keeping voltage, second restraining coil, 5 band-type brakes stop ladder thereby elevator is decelerated to relative pulsation-free speed with escalator.In addition, select the appearance value of different electric capacity and the resistance of resistance, can select discharge time constant neatly, promptly selected delay time.
