Description
Technical field
The present invention relates to elevator accessory technical field more particularly to a kind of cage door lock devices.
Background technology
Cabin elevator in the long-term use, inevitably will appear various failures, wherein improper stop transport is cabin elevator
In common one of failure, degeneration accident, existing elevator are caused to prevent passenger from opening car door without authorization when elevator is stopped transport
It is typically provided cage door lock, needs to meet according to the design for being directed to cage door lock in standard GB/T 7588-2003 claimed below：
" when elevator is parked in leveling zone because of failure, trapped person has the ability to implement and save oneself in sedan-chair, by pushing gate aside, makes car door lock and layer
Door-lock opening is completed to save oneself；For elevator because failure is parked in non-leveling zone, car door lock locks gate, avoids trapped person in sedan-chair logical
It crosses and pushs gate aside and fall hoistway.”.The realization of the above effect need to depend on cage door lock that can automatically be locked when car door is closed
Tightly, while the closed state for utilizing switch detector to detect cage door lock is needed, however existing switch detector is susceptible to
Accidentally the case where tactile or poor contact, identification of the control system to cage door lock closed state is influenced, there are security risks.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of structure novel stabilizations, and can precisely examine
Survey the cage door lock device of detection door lock closed state.
In order to achieve the goal above, the technical solution adopted in the present invention is：
A kind of cage door lock device includes the fixing lock and active lock of interlock fit, further includes being useful for detection door lock to close shape
The switch detector of state, wherein the fixing lock includes fixed hanging plate, connects with the fixed hanging plate composition horizontal direction sliding
The slide that connects is rotationally connected with the positive latch hook of the slide, and the active lock is formed with the latch portion of cooperation, the switch inspection
It includes jack assemblies and pin component to survey device, and the jack assemblies and pin component are respectively arranged in fixing lock and active lock,
When fixing lock and active lock lock, the jack assemblies and pin component are mutually inserted.
The beneficial effects of the invention are as follows：The cage door lock device of the present invention, passes through latch hook between fixing lock and active lock
With latch portion carry out phase interlocking hook to car door carry out locking prevent passenger from pulling open car door manually without authorization, avoid therefore and
Caused by degenerate accident.In addition, the switch detector used in the present invention is made of jack assemblies and pin component and pacifies respectively
Loaded in fixing lock and active lock, when fixing lock and active lock lock, the jack assemblies and pin component are mutually inserted
To connect, the signal that door lock is turned off finally is sent to the control system of elevator, otherwise jack assemblies and pin component detach
The control system of coherent signal interruption elevator judges that door lock has been opened afterwards；Since jack assemblies and pin component must be accurately aimed at
It is not easy to loosen after grafting and grafting can just be completed, therefore can avoid sending asking for error signal caused by accidentally tactile or poor contact
Condition.
Further, the slide back-welding shape of the fixing lock has horizontal-extending sliding axle, the fixed hanging plate to be formed with
Coordinate the axle sleeve of the sliding axle, and relative level slides between sliding axle and axle sleeve.The present invention with the above structure, utilizes
Relative level sliding is to realize between fixed hanging plate and slide being slidably connected in the horizontal direction between sliding axle and axle sleeve,
Simultaneously using matching both bootable smooth sliding between sliding axle and axle sleeve.
Further, at least two groups of the quantity of the sliding axle and axle sleeve, and at least one set of sliding outer shaft sleeve
There is resetting spring.Structural stability had both can be improved prevented also from sliding axle and axle sleeve at least two groups of the quantity of sliding axle and axle sleeve
Between relatively rotate and provide installation site for resetting spring, slide can be driven to automatically reset using resetting spring.
Further, the slide is formed with postive stop baffle in corresponding active lock side, and anticollision is provided on the active lock
Bolt and threaded block with the threaded connection of the anticollision bolt, the anticollision bolt be horizontally placed on and with the limiting block
Plate is opposite.Cooperated hitting of both being limited and be buffered to active lock when closing using postive stop baffle and anticollision bolt
It hits, additionally due to anticollision bolt thread is connected to the threaded block of active lock, the extension elongation of anticollision bolt is adjusted to adjust
Relative position between active lock and fixing lock between phase interlocking hook rear socket component and pin component.
Further, it is provided with guide groove on the latch hook, while the cooperation guide groove is fixedly connected in the slide front
Axis pin, the axis pin and guide groove relative swing.When latch hook is swung, also relative swing simultaneously, and profit between axis pin and guide groove
The swing angle of latch hook is limited with axis pin and guide groove.
Further, the fixing lock is fixedly installed on car doorframe, and the active lock is installed on car door and with sedan-chair
Compartment door level of synchronization sliding.
Further, the latch hook front is also rotatably connected to directive wheel.Lock can be driven in Elevator landing using directive wheel
Hook swings unlock.
