【摘要】：芬兰汤姆洛克(TAMROCK)公司生产的TORO-1400E型电动铲运机2005年2月开始在铜陵有色金属集团公司冬瓜山铜矿使用,它是矿山的主力铲出矿设备。国外厂家知识产权保护意识强,它们只供操作、保养和维修的基础技术支持,对TORO-1400E型电动铲运机的其它重要方面,如独特的漏电保护器件原理及连锁控制、尤其是卷缆控制系统不涉及,这给卷缆控制系统故障查找和排除带来许多困难。 电动铲运机卷缆压力控制过程是个滞后、非线性的过程,压力变化的机理非常复杂,不易用数学推理方法建立被控过程的数学模型,本文作者在多年实际应用和不断总结的基础上,从硬件选型和软件设计两方面,对TORO-1400E型电动铲运机卷缆控制系统进行了研究,详细分析了卷缆系统的基本组成、基本要求和工作模式,从液压系统的众多参数中,选择卷缆马达进口的压力作为卷缆液压系统被控参数,根据卷缆压力的控制要求,确定控制检测器件,重点以油门位置传感器A301为例,详细分析它的控制算法设计,研究了它的动态响应,从理论上揭示了卷缆系统控制原理和方法,探究了影响卷缆控制系统性能的因素,阐述了卷缆系统的调试、保养和维修的重要性、主要故障的原因及处理方法,这些工作对卷缆控制系统故障排查及以后的国产化,具有很大的研究意义和推广价值。
[Abstract]:The TORO- 1400E electric scraper produced by Tomlock (TAMROCK), Finland, was used in Dongguashan Copper Mine of Tongling Nonferrous Metals Group Company in February 2005. It is the main mining equipment of the mine. Foreign manufacturers have a strong awareness of intellectual property protection, they are only for operation, maintenance and repair of the basic technical support, other important aspects of the TORO- 1400E electric shovel, such as unique leakage protection device principle and chain control, Especially, the winding cable control system is not involved, which brings many difficulties to the fault detection and troubleshooting of the winding cable control system. The pressure control process of electric shovel coiling cable is a lag, nonlinear process, the mechanism of pressure change is very complex, and it is difficult to establish the mathematical model of controlled process by mathematical reasoning method. On the basis of many years' practical application and continuous summary, the author has studied the cable winding control system of TORO- 1400E electric shovel from the aspects of hardware selection and software design, and analyzed the basic composition of the winding system in detail. Basic requirements and working mode, from the hydraulic system of many parameters, select the coil motor inlet pressure as the control parameter of the coil cable hydraulic system, according to the control requirements of the coil cable pressure, determine the control detection device, Taking the throttle position sensor A301 as an example, the control algorithm design of A301 is analyzed in detail, its dynamic response is studied, the control principle and method of coil cable system are revealed theoretically, and the factors affecting the performance of coil cable control system are discussed. This paper expounds the importance of commissioning, maintenance and repair of the winding cable system, the causes of the main faults and the treatment methods. These work have great research significance and popularization value to the troubleshooting of the winding cable control system and the localization of the cable control system in the future.
