Description
Technical field
The utility model belongs to a kind of braking performance test technical field, is specifically related to a kind ofly be applicable to the intelligent apparatus that electromagnetic brake under multi-load operating mode carries out braking moment detection.Apply this device and on the basis not changing any parts, the brake function test to different size detent can be realized.
Background technology
According to relevant regulation, one or more detent should be at least installed in elevator, the Main Function of detent is, when preventing elevator in unexpected power-off or occur abnormal suddenly, can brake elevator, ensure the safe handling of elevator, need during detent installation to carry out detecting and debug, make the braking moment size of detent reach corresponding requirement.
Utility model content
The purpose of this utility model is to provide a kind of convenient test, the electromagnetic brake high-velocity zone of use safety carries braking moment test platform under operating mode.
The utility model comprises supporting frame, variable-frequency motor, moment output shaft, torque and speed sensors, moment brake axle, electromagnetic brake, at least one flywheel gear, at least one switching device, described moment output shaft and described moment brake axle are supported on support frame as described above body by support level, described variable-frequency motor is connected by shaft coupling one end with described moment output shaft, one end of described torque and speed sensors is connected to the other end of described moment output shaft by shaft coupling, another end of described torque and speed sensors is connected with described moment brake axle by shaft coupling, be connected between described electromagnetic brake and described moment brake axle, described variable-frequency motor, torque and speed sensors is connected on support frame as described above body respectively by support, each described switching device is separately fixed on same described moment output shaft, each described flywheel gear difference clearance fit is on described moment output shaft, described flywheel gear, switching device respectively mutual one_to_one corresponding coordinate, and in the below of each described switching device, correspondence arranges administration of power supply respectively.
Administration of power supply described in the utility model is made up of carbon brush, air cylinder device, and each described air cylinder device is separately fixed on support frame as described above body, and each described carbon brush is separately fixed at the free end of described cylinder.
For being nested with mode between flywheel gear described in the utility model and described moment output shaft.
The operation of the utility model variable-frequency motor and air cylinder device is all controlled by PLC device; Switching device is fixed on moment output shaft, and flywheel gear then coordinates with moment output shaft clearance, and can control moving axially of flywheel by switching device, to realize being separated and joint of switching device and flywheel gear; Administration of power supply is made up of carbon brush and air cylinder device, wherein the carbon brush of corresponding sequence number is fixedly connected with air cylinder device, when air cylinder device is up, carbon brush just can contact with switching device and be that it is powered, now switching device just manipulates flywheel gear and moves axially thus make both compact siro spinning technology, realizes the synchronous axial system of flywheel gear and moment output shaft.
For the disc brake of a certain specification, corresponding flywheel load is selected by PLC, it is up that PLC just can control one or more air cylinder device, carbon brush corresponding under the promotion of air cylinder device just contacts with switching device and provides electric energy, switching device and flywheel gear become engagement state from released state, flywheel load is just successfully applied on moment output shaft, thus realizes the simulation of different loads operating mode.For the detent of different size, the rotating speed under its actual condition is also not quite similar, and now can simulate its high-speed cruising state by the running frequency changing variable-frequency motor.After the simulation realizing load and speed conditions, electromagnetic brake and variable-frequency motor power-off is simultaneously controlled by PLC device, now variable-frequency motor just becomes free rotation state from high-speed cruising state, electromagnetic brake just becomes on-position from release conditions, on this basis, the braking moment of detent in braking procedure relation over time is successfully detected by torque and speed sensors.After having tested, just control cylinder device is descending for PLC, and carbon brush is separated with switching device, and switching device and flywheel gear become released state again from engagement state.
The utility model technology, rational in infrastructure, simple, performance safety is reliable, intelligence degree is high, easy to use, and there is certain flexibility, avoid different braking device all needs to change flywheel at every turn situation when carrying out braking performance test, improve production efficiency, alleviate labor strength.
