Technical field
The present invention relates to anti-fall devices, and in particular to the device of a kind of combination advertisement and the anti-fall prompt of elevator.
Background technique
Now, with the continuous development of urban construction, skyscraper is increasing, and elevator has extensively in real life
Utilization.Elevator has irreplaceable role, but elevator in real life as running tool vertical in skyscraper
The phenomenon that falling happens occasionally.
Elevator anti-fall device in the prior art, mostly uses greatly photoelectric eye, once discovery elevator overspeed decline.Limit
Fast device can allow driving motor to shut down first, if driving motor does not still stop, limiter of speed, which will promote safety tongs, to be made
Its grip track forces carriage to be stuck on guide rail, once but any part failure of braking system or failure, elevator will be straight
Pendant is connect to elevator shaft bottom, though shaft bottom is equipped with buffer unit and still may cause electricity when elevator falls by higher floor
The injures and deaths of personnel in ladder.In order to avoid the generation of above-mentioned used during elevator falling accident, the hair of number of patent application CN201610473593.2
Bright patent discloses a kind of anti-fall mechanism of the elevator with buffer unit, by the way that block is arranged on the borehole wall and is connected with spring
Locking sliding block is arranged in float plate on the top of the car, and beating for Manual operation mechanism messenger industry control lockmaking limited slip block is arranged in carriage
It opens and elevator is made to stop tenesmus.Although foregoing invention can prevent falling for elevator, it does not have at anti-misoperation setting and elevator
Do not have suggesting effect when dangerous situation, is easy the best opportunity that measure is saved oneself in panic-stricken passenger.
Summary of the invention
The purpose of the present invention is to provide one kind to have effectively buffering, and can be manually operated in used during elevator falling prevents elevator
Fall and combine the device of advertisement and the anti-fall prompt of elevator.
To achieve the goals above, the present invention provides the device of a kind of combination advertisement and the anti-fall prompt of elevator, including carriage,
Guide rail, stop slider, block, centrifugal clutch, safe pull rope, safety box, display system, car top top is equipped with and guide rail
The rolling guide shoe of connection is rolled, car roof face is symmetrically arranged with the sliding slot being fixedly connected with carriage, and stop slider is arranged in sliding slot

Urgent prompt video is implanted in display system, when switching switch triggering, display system is switched to the urgent prompt video of broadcasting, gear
Block is arranged on the borehole wall, and buffer spring is provided on block.
The principle of base case of the present invention is:
When elevator operates normally, the rolling guide shoe revolving speed on lift car is lower, be fixedly connected with rolling guide shoe from
The drive end revolving speed of centrifugal clutch is relatively low, at this point, the centrifugation body being slidably connected on centrifugal clutch drive end is due to centrifugation
Power it is too small and can not be with the driven end in contact of centrifugal clutch, the drive end of centrifugal clutch and driven end are in discrete state,
Transmission shaft does not rotate, and the lever of stop slider front end stretches out under the active force of tension spring into sliding slot, keeps off before stop slider
End, stop slider can not be protruding, and pressure spring is in confined state, at this time the contents such as display system normal play advertisement, peace
Full box is sheltered from by box cover, and the passenger in carriage can not contact and control pull ring.When elevator acceleration out of control is fallen downwards, this
When the rolling guide shoe faster rotational speed that is in rolling contact with guide rail, the faster rotational speed of centrifugal clutch drive end, centrifugal clutch is actively
End is in closed state with driven end, and the transmission shaft connecting with driven end and then rotates, and is wrapped in the drawstring lower end on transmission shaft
It is moving upward, the box cover upward sliding connecting with drawstring lower end keeps the pull ring in safety box exposed, and the passenger in carriage can
Pull ring is contacted, switching switch is touched when the box cover of upward sliding and switching switch contact, display system plays urgent prompt view
Frequently, it prompts the passenger in carriage that pull ring is pulled to carry out emergency braking and is connected to drawing when the passenger in carriage pulls downward on pull ring
Safe pull rope on ring is acted on by the commutation of pulley, is lifted up the safe pull rope for being connected to arresting lever upper end, is mentioned upwards
The safe pull rope risen makes arresting lever upward sliding leave sliding slot, and under the thrust of pressure spring, stop slider is stretched out horizontally outward, stop
The free end of sliding block rides on the buffer spring on block, prevents carriage from falling downwards by buffer spring buffering backstop.
The beneficial effect that this programme generates is:
One, this programme is provided with anti-misoperation apparatus, and the passenger when elevator operates normally in carriage can not touch pull ring,
Prevent passenger's maloperation from carrying out emergency braking.
Two, be provided in carriage and play urgent prompt video in car speeding tenesmus, first time prompt passengers into
Row emergency braking improves the safety coefficient of carriage.
Further, the optimization as basic scheme, the stop slider are cylindrical bodies, and the sliding slot is round sliding slot, side
Just processing and assembly.
Further, the optimization as basic scheme is provided with gag lever post in the safety box, and the pull ring, which is hung up, to be limited
On bar, prevent the elevator operated normally the inertia that pull ring generates when uplink starts or downlink stops from lever is surprisingly drawn
It is dynamic.
Further, the optimization as basic scheme is connected with contact plate on the buffer spring so that when stop slider with
Buffer spring uniform force when buffer spring contacts improves buffering effect.
Further, the optimization as basic scheme, on the borehole wall, the position of link stopper to work as sedan-chair the block vertical distribution
When compartment is forced to stop, the elevator door of car door face corridor, convenient for succouring the passenger in carriage.
Further, the optimization as basic scheme, the box cover are made of transparent organic glass, have transparent visual and prevent
Quick-fried performance.
