Description
Technical field
The utility model relates to a kind of safety guard, especially can prevent door-opened elevator slip ladder device.
Background technology
Elevator is a kind of special equipment, there will be fault unavoidably in using.When fault appears at brake system, work the mischief probably can to the personal safety of user.If lift facility in use not enough the or steel rope of elevator braking force after leveling opening with traction sheave skids and drop-gear box turbine broken teeth time, so elevator just there will be enabling and slips terraced phenomenon.(underloading) up slips the phenomenon that car or (being fully loaded with) slide down.On to slip or in downslide process; because firm commencing speed does not reach protection device for over-speed ascending or velocity limiter safety tongs operation condition; now safety component can not available protecting, when now someone stands between Room door and gate, elevator will be caused the shearing accident of personnel.
Utility model content
Slipping the potential safety hazard of ladder to eliminate to open the door, being necessary to provide a kind of door-opened elevator that can prevent to slip the device of ladder.
The utility model relate to a kind of prevent door-opened elevator slip ladder device, comprise and slip terraced inductor, velocity limiter control setup and velocity limiter, describedly slip terraced inductor and comprise elevator switch door detecting device and elevator displacement detector, elevator can be detected whether be moved under door opening state, the terraced inductor that slips is connected with velocity limiter control setup signal, controls velocity limiter stop elevator by this velocity limiter control setup.
The utility model detects slip scalariform state control velocity limiter and brake elevator by slipping terraced inductor; this device can ensure elevator when ladder is slipped in enabling when speed does not reach protection device for over-speed ascending or velocity limiter safety tongs operation condition; first action protection device for over-speed ascending or velocity limiter safety tongs in advance, ensures elevator elevator action when not leaving onlocking zone when ladder is slipped in enabling.

Following detailed description of the invention will further illustrate the utility model in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
As shown in Figure 1, of the present utility model a kind of prevent door-opened elevator slip ladder device 100, comprise and slip terraced inductor 10, velocity limiter control setup 20 and velocity limiter 30, describedly slip terraced inductor 10 and comprise elevator switch door detecting device 11 and elevator displacement detector 12, first elevator switch door detecting device 11 detects the on off state of elevator door, under the state of opening the door, whether elevator displacement detector 12 detects elevator in real time and is moved under door opening state, the terraced inductor 10 that slips is connected with velocity limiter control setup 20 signal, velocity limiter 30 stop elevator is controlled by this velocity limiter control setup 20.
In the embodiment depicted in figure 2, described elevator displacement detector 12 comprises flat bed inductor 121, up inductor 122, descending inductor 123 and the induction pieces 124 that arrange corresponding to it, and described up inductor 122, flat bed inductor 121 and descending inductor 123 set gradually from the bottom to top.Consider that the onlocking zone of door lock is less than 500mm when installing inductor, therefore, described up inductor 122, between flat bed inductor 121 and descending inductor 123, interval is less than 500mm.Descending inductor 123 above responds to the descending action of elevator, sends elevator downgoing signal; Middle flat bed inductor 121 induction door district's action, determines whether elevator arrives flat bed position; Up inductor 122 below responds to the up action of elevator, sends ascending for elevator signal.
Preferably, described up inductor 122, between flat bed inductor 121 and descending inductor 123, interval equals 300mm.As long as make elevator elevator after leveling opening have mobile from flat bed 300mm time, car safety in advance first action will be made.
Preferably, described induction pieces 124 is the magnetic isolation plate of elevator hoistways, and described up inductor 122, flat bed answer device 121 and descending inductor 123 to be YG-1 inductor.
Preferably, described velocity limiter 30 is the fast GBPD velocity limiter that reaches, and described velocity limiter control setup 20 is electromagnet.
Preferred further, described electromagnet is arranged on the both sides of described velocity limiter 30, and when electromagnet obtains electric, adhesive pulls velocity limiter 30 depression bar to make velocity limiter 30 action toward pressing down.The installation of electromagnet utilizes the fast safety tongs axes experimental principle reaching machine room, and the through electromagnet that automatically resets that the present embodiment adopts fastly reaches original-pack supporting electromagnet, so installation site and suction, stroke can meet the requirements.
Concrete control process is as described below: when Elevator landing, flat bed inductor 121 sends flat bed and to put in place signal, and whether elevator switch door detecting device 11 detects elevator door and open and send elevator door opening signal.When two signals meet simultaneously, up inductor 122 and descending inductor 123 start detection, whether induction elevator is subjected to displacement under the state of opening the door, when up inductor 122 detects the up action of elevator, by the electromagnetic actuation of described velocity limiter control setup 20, promote the depression bar action speed limiter 30 of velocity limiter 30 to link safety tongs (bidirectional safety tongs) stop car, when descending inductor 123 detects the descending action of elevator, by the electromagnetic actuation of described velocity limiter control setup 20, promote the depression bar action speed limiter 30 of velocity limiter 30 to link safety tongs (bidirectional safety tongs) stop car.
Be appreciated that those skilled in the art also can do other changes in the utility model spirit, as long as it does not depart from technique effect of the present utility model.These changes done according to the utility model spirit, all should be included within the utility model scope required for protection.
