Description

A kind of control method of remote switching-off of elevator without machine room and control setup
Technical field
The present invention relates to a kind of control method and control setup of remote switching-off of elevator without machine room, particularly a kind of control method and control setup that uses permagnetic synchronous motor to make the remote switching-off of elevator without machine room of driving.
Background technology
Machine-roomless lift is not owing to there is machine room, when being parked in, Lift out of order, power failure or elevator emergency situation such as can't move in the middle of the floor, or when carrying out necessary special project maintenance, it just unlike organic machine room-free elevator available hand turning gear realize artificial mobile car.At present, to machine-roomless lift, the mechanical types that adopt towing machine manufacturer to provide are opened a sluice gate system more, it need open band-type brake by force by specific steel wire rope yarn personnel selection worker, though this mode can achieve the goal, but there is sizable deficiency in actual use, as: machinery is opened a sluice gate line and is not allowed too much bending, too much bending can cause the internal resistance of opening a sluice gate line to increase, and the own internal resistance of opening a sluice gate line owing to machinery is very big, it is not in place to cause and open a sluice gate difficulty, reset, and makes drg normally not open or normally to reset, and has very big potential safety hazard; Nor can be to the necessary security state, whether shut etc. as all doors and to detect.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of simple to operate, control method and control setup of opening a sluice gate to be easy to remote switching-off of elevator without machine room, very big manpower was not opened when this control method and control setup did not need mechanical remote to open a sluice gate, and did not need the special locus of opening a sluice gate yet.
For solving the problems of the technologies described above technical scheme of the present invention: a kind of control method of remote switching-off of elevator without machine room.This method adopts the UPS emergency source of electrical power that brake coil is applied power supply, and power supply realizes opening a sluice gate to brake coil, outage realizes closing lock to brake coil by control.
In the control method of above-mentioned remote switching-off of elevator without machine room, to the safety return circuit and the loop of the door lock that detect elevator before the brake coil power supply earlier, only just power supply realizes opening a sluice gate to brake coil under the safety return circuit of elevator and the normal condition of loop of the door lock.
A kind of remote switching-off of elevator without machine room control setup.Comprise emergency source of electrical power UPS, control loop, brake coil, described control loop comprises emergency starting key switch SM1, the emergent button SM2 that opens a sluice gate, and emergency source of electrical power UPS opens a sluice gate button SM2 by meeting an urgent need and is connected with brake coil with emergency starting key switch SM1.
In the above-mentioned remote switching-off of elevator without machine room control setup, also comprise the safety door latch testing circuit, this safety door latch testing circuit is connected with described control loop.
In the aforesaid remote switching-off of elevator without machine room control setup, described safety door latch testing circuit comprises that safety return circuit, loop of the door lock and safety door latch detect contactless switch KM5; Safety return circuit connects loop of the door lock, and loop of the door lock attachment security door lock detects contactless switch KM5.
In the aforesaid remote switching-off of elevator without machine room control setup, also comprising emergent starting contactor KM4 and the dislocation phase relay of opening a sluice gate, this is emergent opens a sluice gate starting contactor KM4 and is connected with described control loop with the dislocation phase relay.
In the aforesaid remote switching-off of elevator without machine room control setup, also comprise emergency door district switch and rescue position indicator, this emergency door district switch is connected with described control loop with the rescue position indicator.
Beneficial effect: compared with prior art, UPS emergency source of electrical power remote switching-off of the present invention is different from mechanical remote opens a sluice gate, it adopts the power supply of UPS emergency source of electrical power, detecting under the necessary security requirement prerequisite, by special emergency starting key switch and the emergent button of opening a sluice gate, realize opening a sluice gate for the brake coil supply regular power by control, outage realizes closing lock to brake coil, simple to operate, open a sluice gate easily, very big manpower is not opened when not needing mechanical remote to open a sluice gate, do not need the special locus of opening a sluice gate yet, and do not exist because the mechanical internal resistance of opening a sluice gate line causes yet and open a sluice gate difficulty, it is not in place to reset, make the drg drg of can not normally opening or normally reset, thereby cause bigger potential safety hazard.UPS emergency source of electrical power single step of releasing electric energy supports the continuous working of conventional brake device more than 15 minutes, can satisfy car fully and move time requirement when the largest floor spacing.
For preventing that lay man from operating or by maloperation, the present invention is provided with special emergency starting key switch, for full-time staff's keeping, only open the emergency starting key switch, the as prescribed procedure operation could start the emergency relief function.For guaranteeing the person, the equipment property safety in the emergency relief process, the present invention is provided with emergency relief necessary security condition and detects, when disconnecting total power switch, when starting the power supply of UPS emergency source of electrical power, whether the safety return circuit and the loop of the door lock that at first detect elevator be normal, after satisfying above condition, could start next step and open a sluice gate salvage work, guaranteed the person, equipment property safety in the emergency relief process.After satisfying above condition, as long as press the emergent button of opening a sluice gate undetermined, drg promptly is opened.The present invention also is provided with the deixis that puts in place in the car moving process, when car moves to can carry out safety rescue position the time, can light red rescue position indicator in the cabinet, reminds operating personal to close drg, enters next step rescue operation.The invention enables rescue operation in control housing, directly to finish, in cabinet, be provided with the deixis that puts in place in the car moving process, and by monitoring that indicator lamp obtains car position information, made things convenient for the intuitive in daily attention, emergency relief operation and the debug process, the safe condition of rescue process be can also detect simultaneously automatically, the person, equipment and property safety in the emergency relief process guaranteed.The present invention is primarily aimed at and uses permagnetic synchronous motor to make the machine-roomless lift that drives.
