Background technique
Elevator wire rope is suspended on the traction sheave of traction machine, and traction sheave drives wirerope to move by frictional force, traction
Lift car is run up and down.The frictional force of traction sheave and wire rope gearing is exactly traction, elevator at runtime, especially in height
When fast overload direction is run, the traction sheave and wirerope of elevator can be produced relative sliding, and form slipping phenomenon.
Excessive skidding displacement is the hypodynamic embodiment of elevator traction, and traction deficiency will cause great elevator thing
Therefore.In actual use, due to the abrasion of wirerope and traction sheave, the traction of elevator device can continue to decline elevator, when reaching
It, just must more change steel rope or traction sheave when to certain abrasion loss.And in practical operation, the experience of maintenance staff can only be relied on
The maintenance handbook provided with manufacturer judges whether to be replaced, and there are certain artificial error in judgement risks, reduces
The safety coefficient that elevator uses.
Currently, elevator position is determined by rotary encoder umber of pulse on traction sheave, traction sheave for each revolution, compile by rotation
Code device provides fixed umber of pulse, by conversion, can calculate the range ability of lift car.Elevator needs pair before operating normally
Floor position carries out self study operation, by the output pulse of rotary encoder, record each floor gap every number of pulses,
The layer that just can be converted into each floor is high.The each dock floor of elevator can install leveling induction magnetic isolation plate, elevator in hoistway
After car top leveling inductor enters magnetic isolation plate, control system is known that elevator reaches level position.Pass through leveling inductor signal
With floor layer high impulse data, elevator controls Elevator landing at runtime, by encoder pulse data, if going out in purpose stop
Leveling or deficient leveling phenomenon are now crossed, by the position deviation for recording current stop position and practical leveling magnetic isolation plate, so that it may
The amount of slip of elevator out.
But the amount of slip of elevator is obtained by the above method, has the disadvantage that (1) passes through traction sheave rotary encoder arteries and veins
The car position that punching output obtains is relative position, inevitably there is the case where erroneous judgement；(2) because slipping phenomenon can not be kept away
Exempt from, for the accuracy for improving leveling, control system can be by carrying out aligning when leveling magnetic isolation plate, which can shadow
Ring the judgement of slipping phenomenon；(3) it after there is slight slip phenomenon, can be obtained new by relearning floor layer high impulse number
Floor pulse data, adapt to the variation of traction, influence to the hypodynamic judgement of traction.
