Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one: shown in Figure 1, a kind of elevator friction factor type approval test system, comprise bracing frame 12, be located at the platform between bracing frame, be located at the test module on platform and control module 1, described test module comprises stepper motor 8 and speed reduction unit 11, described stepper motor is connected by shaft coupling 9 with speed reduction unit, described speed reduction unit is provided with driven wheel 10, described driven wheel is engaged with semicircle follower gear 4, the straight flange of described follower gear is fixed with channel-section steel 5, described semicircle follower gear is that gear wheel is cut into half, middle semicircle molten iron casting is filled up and welds together with channel-section steel, described channel-section steel is fixed with test platform 3, described test platform both sides are with the test platform center line axle vertical with test platform for axis of symmetry is arranged with, on support frame as described above, the position of respective shaft is provided with bearing, clinometer rule is provided with bottom described test platform, the head fall of described test platform is 0 ° ~ 45 °, described control module comprises the operating terminal 2 connected successively, controller 6, driver 7 and the photoelectric sensor be located on driver, described driver is connected to stepper motor.
In the present embodiment, described operating terminal is touch-screen, and described controller is programmable logic controller (PLC) (PLC).
The long 2000mm of described test platform, wide 600mm.
The described driven wheel number of teeth is 15, and the described follower gear number of teeth is 100, and the ratio of gear of described speed reduction unit is 60:1, segmentation setting 400 pulse/turn, then
Driven wheel rotates 1 ° of umber of pulse needed
;
Follower gear rotates 1 °, and driven wheel rotates
°;
Follower gear rotates 45 °, and the umber of pulse that driven wheel needs send is
=20000;
Therefore, by segmentation be set as 400 pulses/turn, follower gear rotate angle of inclination be 45 ° of calculating, Programmable Logic Controller needs transmission 20000 pulses.
Shown in Figure 2, the control of the present invention to stepper motor adopts three sections of fast modes, is accelerating sections from A point to B point, and B point is at the uniform velocity section to C point, and C point is braking section to D point.If the frequency numeral corresponding to A, D is too low, motor and load motion beginning and at the end of may swing or tremble.If numerical value is too high, motor can start time pulse-losing, and load attempt stop time can make Motor Over Speed.
Achieved the control of friction speed and different angles by PLC program, in these three sections of speed, the control of the anglec of rotation of proving installation can be realized by changing BC section pulse number.The control of the speed of proving installation can be changed by the frequency changing the pulse of BC section.
Shown in Figure 3, PLC and driver adopt common cathode to be connected, and PLC sends to the signal of driver to have pulse signal PLS, direction signal DIR and enable signal ENA.
Collide to prevent the anglec of rotation excessive, the present invention has also carried out amplitude limit to the umber of pulse of input on the touchscreen, and arranges the rotational speed of system, and set 5 gears, 1 grade fastest, and 5 grades of speed are the slowest.
In order to reach the real-time measurement and display to the test platform anglec of rotation, need high counter (HSC) function utilizing PLC, by the input port of the output Puled input of PLC to PLC, number of pulses is carried out converting and is just obtained real-time angular value.
