莱州鲁中矿业有限公司幸台矿区设计年产原铁矿9.9万 t,采用 GKT2×2×1-20型提升机单罐配平衡锤提升。矿区井下共有三个中段,分别为-50中段、-90中段及-130中段。由于提升信号系统中存在多种信号功能不全,造成操作工无法依据该信号系统进行正常提升操作。为此,根据生产实际需要,对原信号系统进行相应的改造。1 原信号系统存在的问题
Laizhou Luzhong Mining Co., Ltd. Yutai mining area designed annual output of 99,000 tons of raw iron, the use of GKT2 × 2 × 1-20 hoist single tank with counterbalance lifting. There are three middle sections in the mine, which are the middle section of -50, the middle section of -90 and the middle section of -130 respectively. Due to the incomplete function of various signals in the lifting signal system, the operator can not perform the normal lifting operation according to the signal system. To this end, according to the actual production needs, the original signal system to make the appropriate transformation. 1 original signal system problems
