Description
Technical field
The present invention relates to a kind of elevator components, be specifically related to a kind of asynchronous door cutter with car door lock.The invention still further relates to and a kind ofly there is the elevator door-motor of the asynchronous door cutter of band car door lock and adopt the gate system of this elevator door-motor.
Background technology
In the process that elevator runs up and down, when car and stop flat bed, the layer door linkage croquet generally moving layer reveal by the door knife-band of car side door machine links together, realizes the action of switch elevator door.
Conventional door cutter comprises synchronous door knife and asynchronous door cutter two type.Synchronous door knife is the action first being realized gripping layer door linkage croquet by door cutter, then gate and layer door again together with link; Asynchronous door cutter is then that a cutter and gate move simultaneously, and before gate and layer door linkage, gate generally will get ahead certain stroke.
When the horizontal throw at the edge, nearest doorway of elevator hoistways inside face and car sill, car door framework or sliding door is larger, in the process that elevator runs up and down, to push aside in non-district of unblanking for preventing passenger and fall hoistway behind the door, require that car will be equipped with the car door lock of mechanical interlocking, and locking must by meeting necessarily required electric safety device to detect confirmation.
Asynchronous door cutter is due to before gate and layer door linkage, and gate generally will get ahead certain stroke, and car door lock design has two kinds of major ways.Mode is the suspension member swivel hook of car door lock being arranged on gate, moves and mobile with gate, and stay hook is arranged on a machine crossbeam, and the tripper of car door lock is arranged on the suspension member of layer door, and tripper moves with layer door and mobile.In this kind of mode, gate must with layer door linkage before rely on the tripper of layer door suspension member to open car door lock, otherwise once gate and layer door linkage, gate and layer door now relative velocity are zero, and car door lock again cannot be opened the tripper of tegillum door.This kind of mode is not very convenient on mounting and adjusting, as Chinese invention patent application CN102015510A.
Another kind of mode is arranged on by car door lock swivel hook a machine crossbeam not move with gate and mobile, stay hook is arranged on the suspension member of gate, stay hook is mobile with the movement of gate, and layer door upper sill frame installs tripper, and tripper does not move with layer door and mobile.In this kind of mode, although car door lock need not consider the interlock time of gate and layer door, structure is often complicated, compares again and takies a space for machine crossbeam, also higher on cost.Disclosed in Chinese invention patent application CN101983170A " car door locking apparatus of elevator ".
