Detailed description of the invention
As Figure 1-3, this utility model is a kind of elevator governor digital test instrument, including Magnet 1, magnetic force induction Device 2, power speed measuring device 3, described power speed measuring device 3 is arranged in fixing device 4, and described fixing device 4 includes support 401 And the fixture 402 being arranged on support 401, described fixture 402 grips power speed measuring device 3, and described power tests the speed dress Put 3 and include that accelerator 301, wiring board process circuit 303, display screen 304, at described accelerator 301, be provided with velocity sensor 302, described velocity sensor 302, display screen 304 all process circuit 303 with wiring board and are connected, and described wiring board processes circuit 303 inside carry algorithm, all speed datas can be calculated and arrange out, and described display screen 304 is made up of LED, described magnetic Ferrum 1 is arranged on the driving wheel edge of elevator governor 5, and described magnetic force induction device 2 is arranged on elevator governor 5 edge covers, And described magnetic force induction device 2 is corresponding with Magnet 1, the two is on same straight line, and described Magnet 1 and magnetic force induction device 2 phase Being optimum distance within 20mm, described magnetic force induction device 2 processes circuit 303 with wiring board and is connected.
During use, being fixed by the fixture 401 of fixing device 4 by power speed measuring device 3, magnetic force induction device 2 is by connecing The wiring board of line and power speed measuring device 3 processes circuit 303 and connects, and is now ready to by elevator governor 5 to be measured, Magnet 1 Magnetic force induction device 2, on the driving wheel edge of elevator governor 5, is then fixed on elevator governor 5 edge covers by absorption, Point-blank, and Magnet 1 and magnetic force induction device 2 optimum distance are maintained in the position that Magnet 1 and magnetic force induction device 2 are put Within 20mm, then power speed measuring device 3 and fixing device 4 entirety are placed near elevator governor 5 to be measured, finally adjust and test the speed Device 3 and fixing device 4 integral position make accelerator 301 lean against on the driving wheel of elevator governor 5, at power speed measuring device 3 Display screen 304 on set the pitch diameter of elevator governor 5, wait to be measured.
During work, accelerator 301 switch of the speed measuring device 3 that turns on the power allows it rotate, due to the accelerator of speed measuring device 3 On 301 driving wheels abutting against elevator governor 5, the driving wheel of elevator governor 5 also concomitant rotation simultaneously, and elevator governor The driving wheel of 5 often rotates a cycle, and Magnet 1 also can rotate a cycle, when Magnet 1 and magnetic force induction device 2 turned position exist Time on straight line, magnetic force induction device 2 can receive the magnetic strength frequency signal of Magnet 1 and be delivered to the circuit of power speed measuring device 3 Plate processes in circuit 303, and wiring board processes after circuit 303 receives signal and calculates girth, show that current elevator governor 5 moves Making speed, now the velocity sensor 302 of power speed measuring device 3 collects the rate signal of accelerator 301, draws and works as preacceleration The speed of device 301, when the driving wheel of elevator governor 5 turns to a certain speed, the mechanical action device of elevator governor 5 is opened Beginning work makes the driving wheel stop of elevator governor 5, now due to Magnet 1 adsorb elevator governor 5 driving wheel edge On, the driving wheel stop of elevator governor 5 Magnet 1 also stop therewith, magnetic force induction device 2 senses the magnetic strength frequency less than Magnet 1 Signal, and obtain the ongoing frequency maximum of elevator governor 5, now maximum magnetic strength frequency signal is passed by magnetic force induction device 2 Being delivered to wiring board and process in circuit 303, wiring board processes circuit 303 and collects the magnetic strength frequency signal of maximum, calculates current The rotation girth of elevator governor 5, thus calculate present speed, it is mechanical action speed V1 of current elevator governor 5, by Process circuit 303 in display screen 304 and wiring board to connect, finally reading speed V1 from display screen 304, simultaneously because elevator limit The mechanical action device of speed device 5 makes the driving wheel stop of elevator governor 5, and the accelerator 301 of power speed measuring device 3 is due to stop Effect of inertia can slow down, and the velocity sensor 302 of the 3 of power speed measuring device can collect the maximal rate signal of accelerator 301, Draw maximal rate V2 of current accelerator 301, equally can from display screen 304 reading speed V2, speed V1 of above-mentioned test For the mechanical action speed of elevator governor 5, speed V2 is elevator governor 5 edge maximum speed of driving wheel when mechanical action Degree.
