[摘 要]针对莱芜电厂火车来煤翻卸过程中由机械、电气联锁与液压系统故障引起的设备对位精度不足、设备禁运停运与设备掉落碰撞等问题,制定了一系列硬件与软件设备的改造方案,并提出利用MapleSim软件完成对液压系统故障的诊断。同时,针对人工摘钩脱钩导致的翻车效率低、人工劳动力浪费的现状,设计了自动摘钩装置,为实现翻车系统的自动化作业提供了技术基础。

[Abstract]Aiming at the problems of insufficient equipment alignment accuracy, equipment embargo shutdown and equipment drop collision caused by mechanical, electrical interlocking and hydraulic system faults in the process of train coal unloading in Laiwu power plant, a series of transformation schemes of hardware and software equipment are formulated, and the use of MapleSim software to complete the fault diagnosis of hydraulic system is proposed. At the same time, in view of the current situation of low overturning efficiency and waste of manual labor caused by manual uncoupling and uncoupling, an automatic uncoupling device is designed, which provides a technical basis for the automatic operation of the overturning system.

翻車机系统是燃煤电厂用于翻卸由铁路敞车运输来的燃煤散料的大型卸车系统,该系统主要通过翻车机与调车系统中的重车拨车机、空车推车机以及迁车台等设备的机械或电气联锁完成火车来煤的卸料。其系统中各独立设备可根据作业运行要求完成独立作业,也可根据生产工艺要求进行联锁作业,例如:翻车机本体可独立进行准确的车辆定位、压车、靠车、回转、喷雾以及起振等操作,同时翻车机还可以与重车拨车机实现联锁,以保证翻车机在完成重车就位—拨车机离开翻车机回转范围—大臂抬起等操作后运行,其系统工艺繁杂、故障点繁多。
现阶段,为保证翻车机系统在整个翻车卸料进程中有序化、安全化进行,其在翻车机控制室与调车系统中的各设备间设置有声光报警、启停信号、紧急停机按钮、事故信号以及预告信号装置。同时,被……
