Stability Of The Jack-up Equipment And Safe Protection Systematic Application Study

Comparing with safe performance of foreign advanced engineering machinery product, ours is bad in performance, low in automation intelligent degree and high rate in crash accident. So crane is selected as an reseearch object to reasearch its safe system and automation intelligence, which is used largely in construction. Firstly , Through to influencing the analysis of its stability factor and consulting foreign advanced technology ,the paper has carried on the discussion to the overall scheme of the safe protection system of the moment limiter that is equipped on the domestic crane , confirm that adopts the control method of digital simulation taking one-chip computer as the core;Secondly, the paper has designed and done the detailed argumentation on the systematic hardware, including to the before passway,the behind passway, the mininmum system and its periphery expand, guard the gate dog, etc, including their circuits and parameters . the software function of the moment limiter has designed and in order to improve systematic anti-interference, the corresponding measure was taken in;The paper on crane balance regulation systematic improvement before working has made discussion also, a simple structure and performance reliable balancing judging device has beeb designed, a balance and judging the regulator has been designed also;Thirdly the electric shock protection system finally has been preliminary discussed in the paper; End in this text, moment limiter system, balancing regulation systemm before working and The electric shock protection system have been made an integrated system ,which have not only improved the systematic performance of whole safe protection but also simplified the organization, easy to operate and control. It can popularize and apply to other engineering machinery to revise slightly the reaserch of crane safe protection system.
