Description
Technical field
The present invention relates to a kind of elevator control system, more particularly to a kind of synchronous control system of double traction machine brakes.
Background technology
Current all elevators are all made of 1 traction machine to promote car, and the nominal load capacity of elevator is limited to traction machine
The parameters such as axle load and power of motor make the nominal load capacity of elevator that can not further increase.
Invention content
The present invention be directed to the problems that 1 traction machine load capacity is limited, it is proposed that a kind of double traction machine brakes it is same
Control system is walked, using 2 traction machines come Synchronous lifting car, the nominal load capacity of elevator can be made to promote 1 times, thus met
Some need the market demand of big load elevator, and when promoting car using double traction machines, the brake of double traction machines is necessary
Keep declutching and band-type brake and having high reliability for absolute synchronization.
The technical scheme is that：A kind of synchronous control system of double traction machine brakes, by 1 program controller PLC
Device, operation contactor, safety relay, band-type brake relay, band-type brake swash by force relay, maintenance voltage resistance, backward voltage and absorb
Resistance, diode, 2 traction machine brakes and 4 brake switch constitute brake coil circuit and control loop；
Brake coil circuit：Power supply by concatenated operation contactor normally opened contact, safety relay normally opened contact, embrace
Lock relay normally open contact, band-type brake swash by force relay normally open contact to 2 concatenated traction machine brake coil power supplies, and band-type brake is strong
Swash relay normally open contact both ends parallel connection maintenance voltage resistance, backward voltage absorption resistance and is connected in 2 with after Diode series
Only concatenated traction machine brake coil both ends, absorbing coil reverse induction electromotive force；
Control loop：The brake switch of 2 linkages of each traction machine brake band, brake switch signal is input to can
Sequence controller is programmed, programmable controller outputs a control signal to operation contactor, band-type brake relay, band-type brake and swashs relay by force
Device, elevator safety loop output a control signal to safety relay.
The power supply is DC power supply, and 2 concatenated traction machine brakes are with model same parameter brake.
The beneficial effects of the present invention are：The synchronous control system of double traction machine brakes of the invention, using 2 traction machines
Carry out Synchronous lifting car, while so that the load capacity of elevator is promoted, solves double traction machine brakes and synchronize and declutch and band-type brake
The problem of, there is high reliability.
Description of the drawings
Fig. 1 is the synchronous control system structure chart of the double traction machine brakes of the present invention；
Fig. 2 is the synchronous control system schematic diagram of the double traction machine brakes of the present invention.
Specific implementation mode
The synchronous control system structure chart and schematic diagram of double traction machine brakes as depicted in figs. 1 and 2, system include 1
Programmable controller, 1 contactor, 3 relays, 2 resistance, 1 diode, 2 traction machine brakes and 4 brakings
Device switchs.3 relays are respectively safety relay（K1 in Fig. 2）, band-type brake relay（K5 in Fig. 2）, band-type brake by force swash relay
（K6 in Fig. 2）, 1 contactor is operation contactor（KM1 in Fig. 2）.Resistance 1 is maintenance voltage resistance RZ1, and resistance 2 is reversed
Voltage absorption resistance RZ2 is attempted by after connecting with diode D1 on brake coil YB1, YB2, is absorbing coil reverse induction electricity
Used in kinetic potential.The normally opened contact of 3 relays and 1 contactor is series among brake coil circuit.Wherein band-type brake swashs by force
Relay K6 normally opened contacts and maintenance voltage resistance RZ1 simultaneously connect.2 traction machine brake coils YB1, YB2 are serially connected.Every
Traction machine matches 2 brake switch respectively（SZD1, SZD2, SZD3, SZD4 in Fig. 2）, brake switch signal, which is input to, to be compiled
Range controller, for monitoring brake opening, closed state.
When elevator safety loop normal condition, safety relay K1 is attracted；When elevator enters operating status, programmable control
Device output signal processed makes operation contactor KM1 be attracted, and output signal makes band-type brake relay K5, band-type brake swash relay by force again after being slightly delayed
Device K6 is attracted, and direct current 220V power supplys add to 2 traction machine brake coils by the normally opened contact of above-mentioned relay, contactor,
Since the electric parameter of 2 brake coils is identical, specified pick-up voltage is direct current 110V, therefore direct current 220V is through partial pressure
The voltage at every brake coil both ends is direct current 110V afterwards, brake obtain it is electric declutch, the action of 4 brake switch, action
Signal is input to programmable controller.After brake declutches 1.5 seconds or so, programmable controller discharges band-type brake and swashs relay by force
K6, normally opened contact disconnect, make direct current 220V power supplys after maintenance voltage resistance RZ1 again to 2 brake coil YB1 and
YB2, thus the voltage at 2 brake coil both ends is reduced.
Since 2 brake coils using same group of power supply and use the mode that is connected in series with, and the machinery of 2 brakes,
Electric parameter is identical, thus can ensure 2 brakes synchronize declutch, band-type brake；If furthermore 1 brake coil damage is (disconnected
Road), then another 1 brake coil can not obtain electric, can also make 2 brakes that can not all declutch；In addition programmable controller pair 2
The declutching of brake, band-type brake situation is monitored in real time, if 2 brakes since failure cause causes 1 brake to declutch, separately
When 1 band-type brake or asynchronous 2 actions, programmable controller can cut off the output signal of band-type brake relay immediately, make 2
Brake band-type brake immediately, avoids the generation of dangerous situation.
