Cable reel electric scraper device is a crucial component design , it might drag the cable in the ground being broken , not only will increase production costs , but also affect the safety of operations. This topic is developed transverse electric scraper research follow-up studies , mainly on how to improve the electric cable scraper device volume work focuses on performance . In this paper a comprehensive analysis of the traditional type ( mechanical , hydraulic and electric type ) cable device works volume , control strategy and work performance, analysis, synthesis , based on the proposed new CNC roll cable device strategy developed the volume of new cable device control program. In the new CNC program implementation, working for electric scraper forward and backward conditions, carried out on the kinetics of the cable reel , through the motor armature current and the cable reel angular acceleration measured directly , according to the work cable reel case the equilibrium equations , the conditions obtained indirectly cable tension in the cable reel shaft torque value generated dynamically . Then through the design of the control system controls the motor armature voltage and electromagnetic brake operation , adjust the volume cable, the cable release rate, to achieve walking mechanism during operation of the volume scraper speed synchronization cable means . Since the synchronous control method for numerical control system response speed than the conventional fast , adjustment quickly , so that the numerical control apparatus of cabling performance than the conventional synchronization control method has been greatly improved. In addition, due to the synchronization performance improvement, but also to avoid the work process interrupt cable, unreeling , rejection of the cable , and enhanced the safety of the equipment . This thesis is based on the control program and works to CYE-2 electric scraper as the research object , modular programming method, independent design and development of a microcontroller as the controller of synchronous control system . CNC roll through cable device simulation experiment to verify the electric cable reel LHD CNC device control strategy is correct.
