Technical field
The present invention relates to the safe operation of elevator, specifically a kind of elevator using electromagnetic induction and function of current design is anti-
Fall device.
Background technology
With the fast development in city, elevator also becomes the indispensable tool of skyscraper traffic, it is our life
Bring convenient also band elevator safety accident.
So just there are many devices for preventing the generation of elevator fall accident, wherein typical device has：
1. the main device of cone of gears cydariform gradual anti-falling safety device composition cone of gears cydariform gradual anti-falling safety device has：Tooth
Wheel, centrifugal speed-limiting device and cone drum brake.
Its operation principle is:When the speed of service of the objective of defense (construction elevator cage) downlink reaches the action speed of calibration
When spending, centrifugal speed-limiting device gets rid of block displacement (suitable pawl), and band mantle drum (suitable ratchet) is moved to brake band, contacted
And braking moment is generated, while disk spring group is compressed, and the size of decrement is measured, and can determine whether its specified braking by calculating
Braking distance when load.
The device advantage is brief and practical, and device is smaller, can facilitate realization anti-drop function.But disadvantage is to limit
Factor processed is more, is easy to happen：It is centrifugal 1. the centrifugal unstable 2. safety integral installation of speed-limiting device movement speed is tested
Speed-limiting device action is normal but cannot brake normal when 3. centrifugal speed-limiting device movement speed calibration, integral installation examination after assembling
When testing, movement speed deviate normal value 4. bore drum brake maximum braking moment do not reach requirement or maximum braking moment not
The problems such as stablizing, the factors such as ponding, long-pending oil, sundries, corrosion are easy for impacting its work, and the shelf-life is short, and one
Year must be replaced primary.
2. elevator safety gear
For the device when elevator speed is more than 1.15 times of normal speeds, elevator governor action passes through speed limiter wire rope
The safety tongs pulling apparatus on car is pulled, the safety tongs of car both sides is made to act, safety tongs tightly vises guide rail, to
Car is set to brake.The device can effectively control elevator, the whereabouts of elevator can effectively be controlled under normal condition, but occasional occurs
Failure event, numerous elevators before fall down from the building tragedy have it is many be exactly therefore caused by.
The miscellaneous elevator anti-fall device of generally existing is gone back on the market, although also favorably being controlled with electromagnetic induction principle
Switch, and the principle for allowing elevator to stop is still common mechanical braking.
The all generally existing safeties of the above product cannot be reached very, it is difficult to overhaul, deceleration of elevator stops
After the problems such as cannot being parked in Stall, and it is also high for the recondition expense of old-fashioned elevator.
Invention content
Elevator anti-fall device is safe and reliable, low cost, be easily installed, be easy to overhaul in order to make by the present invention, and spy proposes a kind of
Utilize the elevator anti-fall device of electromagnetic induction and function of current design.
Thus the technical scheme is that, it is a kind of using electromagnetic induction and the function of current design elevator anti-fall device,
Including lift car, lift car is drawn by motor run along guide rail in the elevator shaft, it is characterised in that：The elevator
Car is aluminum or steel car, and in lift well two sides, vertical uniform intervals are provided with multigroup first electromagnetic coil and more
A velocity sensor, the first electromagnetic coil has control relay and velocity sensor and power supply by connection, wherein controlling
Relay processed is normally open, and when lift car decrease speed is more than setting speed, velocity sensor is by controlling relay
Normally closed that multigroup first electromagnetic coil is made to generate magnetic field, lift car moves in magnetic field at this time, and lift car itself can be made to generate
Induced current makes lift car slowly decline by the effect of Ampere force, the constant speed for preventing lift car from falling.
Further improve is：It is corresponding to be equipped with multigroup second electromagnetic coil in the bottom of lift well, work as lift car
When multigroup second electromagnetic coil fast approaching of bottom and lift well bottom, the effect meeting Lift elevator car in magnetic field makes electricity
Terraced car slowly declines.
Further improve is：It is additionally provided with multigroup spring assembly in the bottom of lift well, which corresponds to electricity
Terraced cage bottom plane.
Advantageous effect：
The present invention when being fallen down from the building suddenly using lift car, when lift car decrease speed is more than setting speed, velocity pick-up
Device makes multigroup first electromagnetic coil generate magnetic field by the way that control relay is normally closed, and lift car moves in magnetic field at this time, can make
Lift car itself generates induced current, by the effect of Ampere force, the constant speed for preventing elevator from falling, makes elevator car
Compartment slowly declines.Lift car itself is aluminum or steel car at this time, is equivalent to a conductor, the cutting magnetic induction in magnetic field
Line, car itself generate vortex by upward Ampere force, gradually slow down, play the first protective effect again.
It is corresponding to be equipped with multigroup second electromagnetic coil in the bottom of lift well, when lift car bottom and lift well bottom
Multigroup second electromagnetic coil fast approaching when, the effect in magnetic field can Lift elevator car, so that lift car is slowly declined.In electricity
Identical as lift well side principle when ladder reaches Stall bottom, the second electromagnetic coil will produce vortex and elevator prevented to decline, and rise
To the second protective effect again.
It is additionally provided with multigroup spring assembly in the bottom of lift well, which corresponds to lift car bottom plane, energy
It is enough that final effective buffer protection, that is, third protective effect again are provided to lift car.
