Background technology
Along with the raising of people's living standard, elevator has become convenient tool indispensable in people's daily life, but
When passenger takes elevator, elevator door is surprisingly opened the accident caused again and again send out due to apparatus for controlling elevator fault or mechanical breakdown
Raw, make people that elevator to produce a kind of feared state of mind.
Summary of the invention
The technical problem to be solved is to provide a kind of simple in construction, convenient for installation and maintenance, it is to avoid because of elevator control
The system failure processed or mechanical breakdown and the elevator cage door and the layer door that cause surprisingly are opened, protection car passenger and stop passenger safety
Prevent the controlling organization that elevator surprisingly opens the door.
The technical scheme is that a kind of controlling organization preventing elevator from surprisingly opening the door,
Including car, hoistway, door electromechanics machine controller, door cutter electric machine controller, door electromechanics machine, door cutter motor and power supply, described car
It is positioned at described hoistway；Described door electromechanics machine controller, door cutter electric machine controller, door electromechanics machine, door cutter motor and power supply are the most solid
Surely being arranged on described car top, described door electromechanics machine controller is by door electromechanics machine described in connection, described door cutter motor
Controller passes through connection door cutter motor, and described door electromechanics machine controller and door cutter electric machine controller are connected by lines in parallel
It is connected with described power supply by circuit afterwards, the described door cutter motor each fan by hoistway described in described door cutter motor controller controls
Layer door folding, described door electromechanics machine is by the folding of the gate of car described in described door machine motor controller controls；
Also include elastic component, door electromechanics brake, door cutter electromotor brake, contact switch and with described contact switch pair
The switch answered connects sheet, and described car top is fixedly installed fixing seat A, described car top and in described fixing seat A and institute
State and be provided with travel(l)ing rest between the gate of car；Described travel(l)ing rest can be along the gate of described fixing seat A and described car
The direction of vertical join line is horizontal-extending to reciprocatingly slide, and one end of described elastic component and described fixing seat A are fixing to be connected, the other end and
Described travel(l)ing rest is fixing to be connected；
Described door electromechanics brake and door cutter electromotor brake are fixing with the two ends of described travel(l)ing rest respectively to be connected, institute
State a dynamo-electric brake and brake or depart from described door electromechanics machine with the shift reciprocately of described travel(l)ing rest, described door cutter motor
