It hits, experiment lamps and lanterns are located at below solenoid valve.
The radio remote control circuit control apparatus for impact testing of the embodiment of the present invention carries out the electricity of shock-testing to lamp outer casing
The road course of work is as follows:
Before test, as shown in the schematic device of Fig. 5, lamps and lanterns are placed on percussion mechanism in the following, guarantee shock surface with
Direction be hit vertically (power is avoided to decompose), device is given to be powered, inputs 220V AC voltage, voltage is dropped by transformer T1
Pressure obtains AC12V voltage, is rectified using BD bridge heap, is filtered using C1, exported surely by voltage stabilizing chip 7812
Fixed direct current DC12V voltage carries out absorption peak voltage using C2, and an electric current has flowed to PT2272 and received control module electricity
Here, PT2272, which is powered, to start to work, as long as there is transmitting infrared signal to arrive, Q2 infrared receiver tube receives signal, Q3 tri- on road
Pole pipe amplifies the signal of Q2, is input to inside PT2272 chip by C3 and R3, and PT2272 handles received signal,
It goes forward side by side the comparison of row address code, if address code then exists to that must go up (address code of PT2272 and PT2262 module on)
Corresponding data output end D0, D1, D2 export high level.
When needing to adsorb the operation of impact hammer by the reversed unwrapping wire of motor, then the SW2 of emission control module is pressed, emitted
This operation trigger signal is input to PT2262 by control module, and the D1 foot of PT2262 turns on, and the signal is carried out address volume
Code, address code A11A10A9 are 010, convert the signal into wireless signal and are emitted, and in receiving control module, by this
Wireless signal is converted to electric signal and amplifies, and is input in PT2272, and the address code of signal is compared PT2272, so
High level is just exported to Q5 in corresponding D1 foot afterwards, and the grid of Q5 is high level conducting, while the normally opened K2-1 of relay K2
It is connected to rotating backward for motor, so motor starts to carry out rotation unwrapping wire by relay, unwrapping wire can be with until electromagnet
Impact hammer is sucked, then decontrols SW2 switch, PT2262 stops transmitting wire size, while the D1 foot of PT2272 stops output high level,
Make the grid low level of Q5, Q5 is in an off state, while relay K2 being made to lose electricity, and the opened point of relay K2-1 is just broken
It opens, motor M stops operating.
When needing to rotate forward the high speed operation of adjustment jump bit by motor, then opening in emission control module is pressed
SW3 is closed, this operation trigger signal is input to PT2262 by emission control module, and the D2 foot of PT2262 turns on, and by the signal
Address code is carried out, address code A11A10A9 is 001, it converts the signal into wireless signal and is emitted, and controlled receiving
In module, this wireless signal is converted into electric signal and is amplified, is input in PT2272, PT2272 is by the address code of signal
It being compared, then just exports high level to Q6 in corresponding D2 foot, the grid of Q6 is high level conducting, while relay K3
Normally opened K3-1 is connected to rotating forward for motor, so motor starts to carry out rotation bracing wire by relay, adjustment is hit
The height of hammer, rising maximum eminence has travel switch to control motor power, needs the height set not stop if reached, then
It is further continued for rising to withstand travel switch SQ1 and disconnecting motor power and stop, playing and avoid motor is past always from pulling up wirerope
Breaking phenomenon.
After everything in readiness, when carrying out release jump bit operation, then SW1 switch, emission control module are pressed
This operation trigger signal is input to PT2262, the D0 foot of PT2262 turns on, and the signal is carried out address code, address code
A11A10A9 is 100, converts the signal into wireless signal and is emitted, and in receiving control module, by this wireless signal
It is converted to electric signal and amplifies, be input in PT2272, the address code of signal is compared PT2272, then corresponding
D0 foot just export high level to Q4, the grid of Q4 is high level conducting, while the normally closed point of relay K1 is connected to electromagnet
On, the normally closed point K1-2 of relay K1 is just disconnected, so that electromagnet loses electricity, magnetic force disappears, and jump bit moment freely falls,
When falling by between LED1 and RL photo resistance, LED sending illumination is mapped to the photo-electric switch of RL by jump bit, keeps RL resistance rapid
Upper height, while the voltage got on RL is higher than R17, LM358 exports more by force the grid that high level reaches Q7 at this time, carries out Q7
Conducting, while SMC solenoid valve must also establish lock by cable, along on falling impacts to lamps and lanterns among SMC valve, jump bit falls jump bit
Afterwards, the light that LED is issued is irradiated on RL again, is reduced rapidly the resistance value of RL, and the voltage got on R17 is higher than RL, LM358 output
Low level, Q7 grid are also low level, and Q7 ends, and jump bit is restricted to prevent secondary rebounce in casing by SMC barrier gate,
To complete outer cover intensity impact test.
During entirely control jump bit is freely fallen, tester may be located remotely from 1-20 meters of test device, avoid rushing
Hammer, which surprisingly goes offline, injures people by a crashing object.
Radio remote control circuit structure of the invention is simple, can far distance control apparatus for impact testing, to lamp outer casing into
Accommodating efficient shock-testing, promotes the safety of test process, while reducing the fatigue strength of manual operation.
The above disclosure is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore equivalent changes made in accordance with the claims of the present invention, is still within the scope of the present invention.
