在安装调试新新煤矿落地式多绳提升机电控设备的过程中发现,该提升机的 JKMK/J—A_2—11□Ⅰ型电控设备存在不受井口把钩工信号控制等五个不符合《煤矿安全规程》第358条规定的问题。本文介绍了用修改原电控设备电路的方法解决这五个问题的经验。经过多次试验改进和一年多的试验运行,修改后的电路解决了存在的五个问题并完全达到了《煤矿安全规程》第358条的规定要求,通过了矿方组织的设计院等有关专家的验收和认证。 During the installation and commissioning of the new coal mine floor-standing multi-hoist electric control equipment, it was found that the JKMK / J-A_2-11 □ Ⅰ electric control equipment of the hoist was not controlled by the wellhead hook signal and so on. Meet the “Coal Mine Safety Regulations” Article 358 of the provisions of the problem. This article describes the use of modified circuit of the original electronic control equipment to solve these five problems experience. After many trial improvements and more than one year of trial operation, the modified circuit solves the five existing problems and fully meets the requirements of Article 358 of the “Coal Mine Safety Regulations” and has passed the design institutes and so on of the coal mine organization Expert acceptance and certification.
