【摘要】：近年,随着煤炭相关工业的快速发展,煤炭的需求量快速增加且高位运行。在煤炭开采过程中,巷道掘进成为制约煤炭开采的一个难点,通过借鉴国内外相关资料,结合显德汪矿现有掘进机使用过程中的情况,即在生产中出现的故障情况,以及维护维修实际,对现有型号为EBZ100型掘进机进行电控系统改造,实现其安全高效运行。在本课题中,由于掘进机改造类似于坦克的升级改造,设备本身较重都在30吨以上,造价在300万元以上,不能随意淘汰。而多数掘进机的落后都表现在电控系统上,所以改造电控系统就成为一种必然,而且改造电控系统成本较低。显德汪矿经过两年对掘进机的论证,决定对电控系统进行全面改造。通过实际工作调研总结出:掘进机在工作过程中会遇到多种情况影响掘进速度,例如电机温度检测元件损坏、保护故障无法启车、电气元件由于振动无法检测电压电流等,这些情况多为电气方面保护的不可靠和掘进机电控系统元件参差不齐所致。通过研究显德汪矿掘进机的使用情况,依据7台掘进机在使用过程中出现故障点等问题,此次改造主要对电控系统信号的采集、处理、转换和输出做了更改,增加了精度的检测器件,主要体现在硬件方面,相关软件由石家庄煤机厂完成。改造方案主要体现在:采用触摸显示屏和BH9综合保护器,替换原有的数码显示管和电机综合保护器,实现了电控系统的集约化,显示直观保护全面;采用FX2N-4AD模块来转换电压电流信号,提高了电控系统的可靠性和控制精度,满足了显德汪矿对掘进机使用的要求。
[Abstract]:In recent years, with the rapid development of coal related industries, the rapid increase and high demand for coal. In the process of coal mining, tunneling becomes a difficulty of coal mining, by referring to relevant information at home and abroad, combined with the Xiandewang mine in the process of using the existing roadheader, which appeared in the fault, repair and maintenance of existing practice, model for the EBZ100 type roadheader electric control system transformation, achieve the safe and efficient operation. In this paper, the upgrading transformation of roadheader is similar to the tank, the equipment itself is heavy in more than 30 tons, cost more than 3 million yuan, can not be eliminated. The most boring machine behind the performance in the electronic control system, so the improvement of electric control system has become a necessity, but also the improvement of electric control system of low cost. Xiandewang after two years of boring machine demonstration, never Set in a comprehensive transformation of the electronic control system. Through the actual research work concluded: roadheader will encounter a variety of impact driving speed in the work process, such as the motor temperature detection element damage protection fault cannot drive, electrical components due to vibration can not detect the voltage and current, these conditions for electrical protection is not reliable and boring machine control system. The use of components caused by uneven Xiandewang mine roadheader through research, on the basis of the 7 roadheader fault point and other issues in the process of using, the transformation of the main acquisition, the electric control system of signal processing, the conversion and output changes, increase the accuracy of the detection device, mainly reflected in the hardware, software is completed by the Shijiazhuang coal machine factory. The reconstruction scheme is mainly reflected in: the touch screen and BH9 protector, to replace the original digital display tube and The motor comprehensive protector realizes the intensification of the electric control system, displays the visual protection completely, uses the FX2N-4AD module to transform the voltage and current signals, improves the reliability and the control accuracy of the electric control system, and meets the requirements of the application of the TD Wang mine to the roadheader.
