5)The output signal of electronic control panel 8 control enabling relay 23 opens elevator door, when detection switch 6 in place of opening the door After detecting that elevator door is opened completely, elevator door is out of service.
Compared with prior art, above-mentioned three kinds of mode elevators are to leave leveling zone in normal driving process and break down to be stranded After people, passenger carries out emergency self-saving function according to the voice message of the Audio Players 15 in elevator inside car, should Passenger inside function guarantee car after elevator is made in the case of being perfectly safe with slow running to leveling zone, put by automatic door opening Go out stranded passenger, stop the maintenance mans such as all operations after door-opened elevator to repair and fix a breakdown.The present apparatus is simple to operate, efficiency Height, consuming time are short, can fast and safely release the passenger inside stranded elevator, eliminate because of the fear of the stranded passengers of long-time Psychology, and avoid rescue personnel from causing unnecessary damage to elevator in rescue operations.
This specific embodiment disclose a kind of elevator faults it is oppressive after saved oneself by three kinds of methods to realize.Wherein, first Kind of method is to provide to open band-type brake power supply and reach flat bed region by coaster mode to traction machine brake gear 3, then individually to Door machine, which provides enabling signal, makes an opening, trapped personnel is released, suitable for layer door interlock switch, car door lock switch, elevator control Device fuse, governor switch, expansion tightening wheel switch, buffer switch, limit inferior switchs, limit inferior switch and phase sequence processed Failure caused by switch contact problem.
Second method is to input maintenance signal to elevator control gear 2 and run up signal, and elevator is by examining at a slow speed Upward running method reaches flat bed region, and then individually providing enabling signal to door machine makes an opening, releases trapped personnel, is applicable In failure caused by safety gear switch contact problems.
The third method is to the He of electronic control panel 8 after outer network source 18 has a power failure by declutch battery 20 or inverter The band-type brake coil of traction machine brake gear 3 provides power supply, opens band-type brake power supply and reaches flat bed region by coaster mode, then Individually providing enabling signal to door machine makes an opening, releases trapped personnel, causes suitable for the outer power-off switch problem of network source 18 Failure.
Wherein, in this specific embodiment, the effect of the inspecting state detection switch 11 is when elevator is in running In input detection when leaving leveling zone action, the switching signal obtains in elevator operation contactor normally closed contact;Safety tongs acts The effect of detection relay 26 is to provide maintenance conversion and to up to elevator control gear 2 after the reception signal of electronic control panel 8 The signal sailed, when elevator reaches flat bed region, then individually providing enabling signal to door machine makes an opening;Safety return circuit detection is opened The effect for closing 12 is when limit inferior switchs, limit inferior switch, pit buffer switch, expansion tightening wheel switch, governor switch, up When overspeed switch any one acts, the signal that declutches is inputted to electronic control panel 8;The effect of door-closing in-place detection switch 5 is elevator Whether detection door is closed mode when being parked among floor, and the switching signal is that independent switch is arranged on the position that shuts up the door carefully On;The effect for the detection switch 6 in place of opening the door is when elevator opens the door in leveling zone, and whether switch detection door is out to use up State, the switching signal are present apparatus independent switches, are mounted in and hold successfully on a position;The effect of jerk detection switch 13 is to work as Elevator when jerk, car top jerk, computer room scram action, will artificially be prohibited in pit jerk, car after the reception signal of electronic control panel 8 Only other all signal outputs of electronic control panel 8;The effect of button 14 of saving oneself is, it is necessary to people when elevator is parked in non-leveling zone Inputted for operation, declutch signal or maintenance and upward signal are provided to band-type brake after the reception signal of electronic control panel 8.
Wherein, the effect of leveling zone detection switch 7 in place be when the car of elevator is parked in leveling opening region, should Switch input signal provides the signal of enabling relay 23, opens elevator door to electronic control panel 8, electronic control panel 8;Door lock break-make The effect of detection switch 10 be when elevator in normal operation because gate interlock disconnect caused by it is out of service when, to electronic control panel 8 Input signal, the reception signal of electronic control panel 8 contactor 21 that declutches backward provide signal and power supply;Blowout detects relay The effect of device 27 is when the fuse of elevator control gear 2 is surprisingly burnt up, to the input signal of electronic control panel 8, electronics control The reception signal of making sheet 8 contactor 21 that declutches backward provides signal and power supply;The effect of control transformer 9 is when elevator faults are backward Electronic control panel 8 and the contactor 21 that declutches are powered;The effect of battery 20 of declutching is when elevator outer network source in the process of running When 18 power down mode, powered to electronic control panel 8 and the contactor 21 that declutches.
Wherein, the effect of contactor 21 of declutching is when the band-type brake of elevator faults backward traction machine brake gear out of service carries For opening band-type brake power supply, make elevator coaster to flat bed region after opening band-type brake;The effect for sealing star contactor 22 is to work as elevator traction Elevator envelope star function is released while the band-type brake of machine brake gear 3 is opened 1-2 seconds and then resetted;The effect of enabling relay 23 It is to provide enabling signal to door opening machine for elevator after elevator reaches flat bed region, opens elevator door;Troubleshooting relay 24 Effect be when electronic control panel 8 receive the signal of safety tongs motion detection relay 26 input when, troubleshooting relay Device 24 exports short circuit emergency loop and door lock, overhauling elevator speed is driven to leveling zone;Power off the effect of output relay 17 Be when electronic control panel 8 receive the arbitrary signal input of signal OR gate lock break-make detection switch 10 of operation detecting switch 16 when Wait, power-off output relay 17 cuts off elevator controlling power supply 4.
Wherein, inspecting state detection switch 11 has two kinds of functions, and the first function is when elevator control gear 2 is in maintenance All output signals of action cut-out electronic control panel 8 during state;Second of function is moved when electronic control panel 8 receives safety tongs When making the signal input of detection relay 26, inspecting state detection switch 11 outputs signal to elevator control gear turn 2 and changes maintenance Signal.The effect for running up output relay 25 is to provide to run up letter to electronic control panel 8 when overhauling elevator is run Number.
In addition, in this specific embodiment, electronic control panel 8 must receive the input letter of door-closing in-place detection switch 5 After number, the contactor 21 that declutches, envelope star contactor 22, enabling relay 23, troubleshooting relay 24, power-off output relay 17th, inspecting state detection switch 11 or run up output relay 25 and can have ready conditions action.
Embodiment of above is only that preferred embodiment of the present utility model is described, not to the utility model Scope be defined, on the premise of the utility model design spirit is not departed from, this area ordinary skill technical staff to this The various modifications and improvement that the technical scheme of utility model is made, the guarantor that claims of the present utility model determine all should be fallen into In the range of shield.
