Description
Technical field
The utility model is related to a kind of escalator fault simulation and fault pre-alarming device.Specifically, one kind is designed to enter
The device of row escalator fault simulation and fault pre-alarming.
Background technology
The multistage chain drive of escalator collection, its complex structure.Because escalator is often in high capacity, long-time
Operation, easily causes the damage of some parts of staircase, leaves potential safety hazard.But nowadays escalator fault pre-alarming device development
Compare delayed.Today in many cases, most of escalator apparatus cannot accomplish fault pre-alarming, can only occur in failure
Just go to save afterwards, it is impossible to accomplish to prevent trouble before it happens, cause great life and property loss.Escalator belongs to buried device,
Its part is numerous, cannot determine that escalator whether there is failure only by range estimation, it is impossible to find and exclude in time, cause very
Big potential safety hazard.And the utility model device can realize the fault simulation and fault pre-alarming function of escalator.Remote
The display screen at process control center can at any time observe staircase operation conditions, check whether there is failure.Once it was found that escalator
There is failure, alarm at once.
Utility model content
The purpose of this utility model is：The problem of fault pre-alarming can not be realized for existing escalator apparatus, is designed
A kind of device that can realize escalator fault simulation and fault pre-alarming.The device is automatic by fault simulation experimental simulation
The failure that staircase is likely to occur in real work.When there is failure to escalator testing stand, the device can be examined in time
Escalator is measured to break down and alarm at once.
A kind of escalator fault simulation and fault pre-alarming device, it is characterised in that：Controller connects motor by wire
And magnetic loader, the start and stop of controlled motor and the applying load of magnetic loader 7.Motor output shaft connects drive chain 4, drives
Dynamic chain 4 is connected by connecting shaft with two-stage chain bar；Two-stage chain bar is step chain 5, and two-stage chain bar passes through loading axis and handrail
Band 6 is connected.Magnetic loader, applying is carried on loading axis.A number acceleration transducer 3 is set in connecting shaft；Motor is provided with
No. three acceleration transducers 9；Loading axis is provided with No. two acceleration transducers 8；Acceleration transducer collection testing stand is believed in real time
Number, signal is sent to data acquisition unit through sensor, and signal is transmitted to display screen through data acquisition unit again afterwards.
Further, motor used is integral type reducing motor.
Main four parts such as including staircase experimental bench, acceleration transducer, data acquisition unit, display screen of the device.
Escalator testing stand include integral type reducing motor, controller, drive chain, step chain, handrail chain,
The parts such as simulative loader.
Reducing motor provides power for staircase；Controller is used to control the start and stop and magnetic loader of staircase normal work
Simulation loading；
Drive chain is that step chain transmits driving force；The operation of step chain guiding step reciprocation cycle (drive chain with
Step chain is driven by axle of the two ends containing sprocket wheel)；Handrail is firmly grasped to stablize body (step chain and handrail band chain for passenger
Bar is driven by loading axis of the two ends containing sprocket wheel).Simulative loader applies load on step chain rivet, under simulation actual environment
Passenger load.
All it is actual escalator institute part in addition to simulative loader.Testing stand is used to simulate escalator reality
The failure being likely to occur under the working condition of border.
Acceleration transducer is arranged on escalator experimental bench bearing and motor foundation bolt, for obtaining testing stand reality
When signal and transmit a signal to data acquisition unit；
Data acquisition unit receives sensor signal by wire, and the acquisition process for signal is simultaneously transmitted to display screen；
Display screen is used for the display of experimental bench live signal, so that staff checks.

Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein
Described specific embodiment is merely to illustrate and explains the utility model, is not limited to the utility model.
Specifically arrangement is as shown in Figure 1 for experimental bench.Escalator fault simulation and motor used by fault pre-alarming experimental bench are one
Body formula reducing motor.
Controller connects motor and magnetic loader, the start and stop of controlled motor and the applying of magnetic loader 7 by wire
Load.
Motor output shaft connects drive chain 4, and drive chain 4 is connected by connecting shaft with two-stage chain bar；Two-stage chain bar is
Step chain 5, two-stage chain bar is connected by loading axis with handrail 6.Magnetic loader, applying is carried on loading axis.Connecting shaft
A number acceleration transducer 3 of upper setting；Motor is provided with No. three acceleration transducers 9；Loading axis is provided with No. two acceleration and passes
Sensor 8；Acceleration transducer gathers testing stand live signal, and signal is sent to data acquisition unit through sensor, and signal is again afterwards
Transmitted to display screen through data acquisition unit.
Motor used is integral type reducing motor.
The covering device structure is as shown in Figure 2.The utility model device include escalator experimental bench, acceleration transducer,
The part of data acquisition unit, display screen etc. four.
Motor switch is opened, testing stand is opened.It is simulation escalator real work state after testing stand is opened, uses
Simulative loader is slowly increased to be fully loaded with to testing stand loading, and slow reduction is loaded to no-load running again afterwards.It is negative increasing
While load, the sensor collection testing stand live signal on testing stand, signal is sent to data acquisition unit through sensor, afterwards
Signal is transmitted to display screen through data acquisition unit again.Display screen shows the real-time working situation of each part of testing stand.
Test to Failure is simulated to escalator experimental bench, the examinations such as bearing fault, the loosening of reduction box lower margin can be simulated
Test.If escalator experimental bench certain part existing defects, then display screen will show the component vibration exception, exist therefore
Hinder and alarmed；, whereas if all parts of experimental bench are in normal operating conditions, alarm would not be triggered.
