本发明公开一种防止干熄焦提升机滑罐的控制系统,包括:干熄焦提升机滑罐检测及控制单元由功能块GTWBC01~GTWBC06、GTWBC12~GTWBC14、GTWBC50~GTWBC53、GTWBC58~GTWBC64、GTWBC69以及GTWBC70构成,在提升机焦罐下滑至距提升机焦罐高位存储值Sref.stored设定距离Ⅰ时,选择一组升降电机为提升机减速机低速传动组,并将所选升降电机传动逆变器的电机速度给定值设为抑制焦罐下滑而设定的低速上升速度值,并释放升降电机传动逆变器的运行使能信号,直到提升机焦罐上升至距提升机焦罐高位存储值Sref.stored的间距小于设定间距Ⅱ,将升降电机传动逆变器的电机速度给定值设为零,同时封锁所选升降电机传动逆变器运行使能信号,在无需增设制动抱闸机构的情况下也避免因提升机传动电机抱闸失灵而导致提升机高位滑罐事故。

    The invention discloses a control system for preventing a dry quenching hoister from sliding. The control system comprises a dry quenching hoister sliding detection and control unit, the dry quenching hoister sliding detection and control unit is composed of functional blocks GTWBC01-GTWBC06, GTWBC12-GTWBC14, GTWBC50-GTWBC53, GTWBC58-GTWBC64, GTWBC69 and GTWBC70, when a hoister coke tank slides down to a set distance I from a high-position storage value Sref.stored of the hoister coke tank, one group of lifting motor is selected as a hoister speed reducer low-speed transmission group, a motor speed given value of the selected lifting motor transmission inverter is set as a low-speed rising speed value set for inhibiting the coke tank from sliding down, and an operation enable signal of the lifting motor transmission inverter is released until the distance to the hoister coke tank high-position storage value Sref.stored is smaller than a set distance II; the motor speed given value of the lifting motor transmission inverter is set to be zero, meanwhile, the operation enabling signal of the lifting motor transmission inverter is blocked, and the high-position tank sliding accident of the hoister caused by the brake failure of the lifting motor transmission motor is avoided under the condition that a brake mechanism does not need to be additionally arranged.
