Step 203, the inspection installing condition of super lifting device and the state of each proximity switch, and return step 201;
Step 204, super lifting device continue to launch;
Step 205, judge proximity switch B whether conducting, if non-conducting, then perform step 204; If conducting, then signal passes in controller by proximity switch B, now can carry out 10 ° of angle operating mode operations or perform step 206;
Step 206, super lifting device continue to launch;
Step 207, judge proximity switch C whether conducting, if non-conducting, then perform step 206; If conducting, then signal passes in controller by proximity switch C, now can carry out the operation of 45° angle operating mode.
So just steady failure-free achieves the detection of super lifting device opening angle and the selection of each operating mode.And super lifting device to close up process contrary with the process of opening, i.e. the conducting successively of C, B, A proximity switch, final realize having surpassed close up, just repeated no more here.
As can be seen from above-mentioned flow process, the control logic of super lifting device opening angle checking system of the present invention is easy to realize, and reliability is very high, is enough to the needs met under each operating mode of super lifting device.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope of request of the present invention protection.
