Embodiment
As shown in Figure 1, a kind of aircraft wheel belt rotation control apparatus, is provided with controller in electrical control cabinet, and the touch-screen that controller is cashier's office in a shop arranged with electrical control respectively and control knob are connected; The output of controller is connected with frequency converter, and frequency converter connects drive motor, driving belt successively, is finally connected with driving wheel, connects aircraft wheel in the excircle contact of driving wheel; Arrange rotary encoder at the excircle of driving wheel, arrange photoelectric sensor at the excircle of aircraft wheel, rotary encoder is connected with controller respectively with photoelectric sensor.
Described controller is connected with pilot lamp, and pilot lamp is arranged on electrical control cashier's office in a shop.
Be provided with well heater in described electrical control cabinet, well heater is connected with controller.
Its principle of work: control device is divided into control and detects two parts, and control section is controlled frequency converter by controller, and then controls drive motor, drive motor drives driving wheel to rotate by driving belt, and driving wheel drive aircraft wheel rotates.By controller to Frequency Converter Control, the frequency of real-time change frequency converter, reaches the speeds control to drive motor, thus adjusts the speed of aircraft wheel.Detection is divided into driving wheel and aircraft wheel velocity measuring, driving wheel velocity measuring adopts rotary encoder mode, be connected with live axle by mechanical installation mode by rotary encoder, driving wheel rotates and drives rotary encoder to rotate, and utilizes rotary encoder to the velocity measuring of driving wheel.It is sticky reflective tape mode on aircraft wheel during the detection of aircraft wheel speed, and coordinate photoelectric sensor to detect, in photo-sensor signal will access controller, utilize controller to the output pulse signal collection of photoelectric sensor, the photoelectric sensor gathered by controller exports the number of turns that a count pulse counting number rotates, be the number of turns that aircraft wheel rotates, and the parameter informations such as second-mission aircraft wheel diameter, girth, finally calculate the actual speed of aircraft wheel, on the touchscreen rotary speed data is shown.
As shown in Figure 2, operation steps is as follows: 1) joining machine wheel belt rotation control apparatus three-phase alternating current 380V power supply, and switch board power source pilot lamp is bright, and touch-screen normally shows; 2) different according to the subjects of aircraft wheel to be tested, corresponding test speed parameter is set on the touchscreen; 3) reflective tape is pasted and tested airplane wheel surface, photoelectric sensor is aligned reflective tape place circumference; 4) turn to according to driving wheel, press touch-screen forward or reverse start button, run indicator is bright, is regulated the speed by touch-screen, and driving wheel starts to rotate; 5) make driving wheel contact with tested aircraft wheel and compress, drive tested aircraft wheel to rotate to testing requirements speed, carry out band and turn test; 6), after having tested, disconnect driving wheel and be connected with tested aircraft wheel, stop drive motor simultaneously, and sever supply power supply.
