mining cable

1 Carrying Principles and Functions of coalmine overhead passenger carrier Driven devices produces power to operate driving wheel and steel cable to carry workers through installation of steel cables to driving wheel.supporting wheel shaft,pressing wheel shaft,and detour wheel as well as tension device,which aims at saving time and conserving energy of Miners. 2 Features of Overhead Passenger Carrier in Coalmines 2.1 Intelligent Control Function of Operation Including selection of operating mode,parameter adjustment,starting control,failure reset 2.2 Intelligent Display Function of Information display of operating mode:displaying "continuous mode","discontinuous mode","maintenance mode","debugging mode" display of operating state:displaying high-speed and low-speed damper brake and unfastening state,emergency stop staring prevention display of failure types:displaying types of personal safetu protection and facility security protection of failure types:displaying types of personal safety protection and facility security protection display of operting data:displaying data ,time,emergency parking erea,current and voltage,temperature 2.3 Intelligent Communication Function language alarm,whistle alarm,flashing alarm 2.4 Intelligent communication Function communication function between head and tail calling function with automatic receiving and program control.The manipulator of monkey vehicle will automatically imitate picking machine and telecast the phone to head,tail or the whole laneway (when there is broadcasting device) if no one answers the off-side phone after it rings three times 2.5 Remote Control Function Providing remote control port and remote control technology of monkey vehicle 2.6 Personal protection (without PLC automatic control system) 2.6.1 Personal safety protection :11 cases(obligatory) Superoinferior offside Emergency stop Overly high speed driving Lower speed slipping Broken rope on slope Prevention the breaking of rope Protection against pendulum Lower positive stop of heavy hammer Rope breaking and emergency stop Electrostatic prevention 2.6.2 Equipment protection :5 cases (matching ) Protection of motor's temperature Protection against efficiency loss of brake Protection of motor,current,and voltage Protection of reducer's temperature Protection of Signal interruption between head and tail(obligatory) When any program occurs.PLC program will inspect signal automatically and passenger carriar will stop at once,sending sound and light alarm and displaying safety program on screen,Thr system will restart as long as obstacle is removed.
