Abstract
The present invention relates to a method using a permanent magnet synchronous motor to drive escalators and moving pavements to achieve braking distance. An acceleration flywheel is arranged and a service brake is used for braking moment so as to meet the requirement of braking distance. When an auxiliary brake is configured, the action of the auxiliary brake lags behind the service brake. When speed exceeds a set value (smaller than 1.4 times of the rated speed) or the defined movement direction is changed by stairs, pedals or rubber belts, the auxiliary brake can act immediately.
Description
Technical field
The present invention relates to a kind ofly drive escalator and moving sidewalk with permagnetic synchronous motor and realize in the safety standard (for example EN115 " manufacturing of escalator and moving sidewalk with safety standard is installed ") method about the stop required distance.
Background technology
Asynchronous motor is all adopted in driving in escalator and the moving sidewalk at present, and by its drive system of component set-ups such as retarder, drg.This system is because parts are more, and therefore work capacity is bigger in manufacturing and fitting process.The synchronous speed of asynchronous motor is higher, generally all at 1500rpm or 1000rpm, to realize in the safety standard unloaded and have the stop distance of carrying operation downwards require more convenient.Because the intrinsic inertia of system of escalator and moving sidewalk has when carrying relatively, particularly the inertia of at full load is less, therefore to satisfy in the safety standard downwards the stop distance range of operation (for example among the EN115 during regulation command speed 0.5m/s stop distance be 0.20～1.00m, the stop distance is 0.30～1.30m during command speed 0.65m/s, the stop distance is 0.35～1.50m) during command speed 0.75m/s, the general method that adds flywheel at motor reel that adopts differs the inertia of sky at full load escalator and moving sidewalk and is not very big.Thereby can satisfy stop required distance under the empty full load conditions with a kind of service brake lock torque, even dispose additional brake, the stop required distance in the time of also satisfying additional brake and service brake and move simultaneously.
When adopting permagnetic synchronous motor to drive escalator and moving sidewalk, can save retarder, not only the fitting work amount is low, and noise is low, efficient is high.But when adopting permagnetic synchronous motor to drive, because its rotating speed is lower, generally about 100rpm, rotating speed far below asynchronous motor, the intrinsic inertia of escalator and the Travelator system inertia of converting brake operating shaft and passenger's load are converted the inertia of brake operating shaft ratio are less mutually so, so the unloaded and total inertia of fully loaded differs greatly.Under the situation that does not dispose very big mass flywheel, distance meets the demands if certain lock torque can make the fully loaded stop, can make unloaded stop distance less than specified value so; If instead certain lock torque can make unloaded stop distance meet the demands, will make fully loaded stop distance so greater than specified value; That is to say that same lock torque can not make the stop distance of sky at full load satisfy the scope of safety standard requirements specified value simultaneously.
When the configuration additional brake, because the lock torque of additional brake requires at least the moment greater than fully loaded passenger load, work simultaneously so work as additional brake and service brake, will can not guarantee the requirement that makes unloaded escalator and moving sidewalk satisfy the stop distance more.
Summary of the invention
The technical problem to be solved in the present invention provides the method that a kind of permagnetic synchronous motor drives escalator and moving sidewalk realization stop required distance, satisfies the requirement of safety standard.
For solving the problems of the technologies described above, permagnetic synchronous motor of the present invention drives escalator and moving sidewalk realizes that the method for stop required distance is: in permagnetic synchronous motor drives a speedup flywheel is set, by chain gear, increase the flywheel rotating speed, improve its influence degree, realize the requirement of stop distance with a kind of service brake lock torque total inertia.
When the configuration additional brake, the action of additional brake lags behind the action of service brake, be dead electricity time-delay braking, but surpass setting value (less than 1.4 times of command speves) or step, pedal in speed, additional brake moved immediately when adhesive tape changed its regulation service direction.
