Description
Technical field
The invention belongs to elevator technology field, and in particular to a kind of elevator autobalance drive system and elevator.
Background technology
Elevator industry extensively using steel wire rope drag device technology, is characterized in that steel wire rope is partly wound on driving and draged in the world now
On running wheel, its one end is connected to car, and the other end is connected to counterweight, make to traction sheave rotate when steel wire rope and traction sheave between produce
Raw frictional force (traction) is so as to drive car and counterweight to run up and down, and counterweight is to be used to provide traction capacity while subtract
Torque on few traction sheave, so as to the power of less motor, but by elevator technology requirement when shortcoming is the weight of counterbalancing
Set car deadweight again plus rated load 50 percent is that balance system is 0.5 standard value, equal to important more unloaded than car
When weigh 50 percent, and car it is fully loaded be to compare heavy 50 percent, Balance is very big so that is suspended on driving wheel
The quiet pulling force reply car load change of the steel wire rope at both ends is fewer of more than the moment unbalance formed during the quality of counterweight,
Make the potential kinetic energy for rotating tendency, producing free-fall acceleration of traction sheave, its potential rate of acceleration is calculated as follows：
With car deadweight 1400kg, rated load 1000kg；
The quality of counterweight is (1000 × 0.5)+1400=1900kg；
Acceleration (rising) during car zero load is：
The acceleration (decline) of car full load is：
When each starting operation of elevator, motor will provide very big torque go accelerate keep his normal speed until
Complete deceleration to stop flat bed, finally also need to the kinetic energy of a reliable mechanical hatching gate locking traction sheave rotation, force car quiet
It is only motionless；Problem is the brake skin bit wear out failure once mechanical hatching gate, fails to find to change in time, will make car and dash forward
So slip away so that passenger is likely to occur security incident.
Based on technical problem present in above-mentioned existing elevator, there has been no the solution of correlation；Therefore there is an urgent need to seek
Effective scheme is sought to solve the above problems.
