Kemei teaches you how to effectively prevent oil rope from getting out of the groove
Someone asked what to do when the oil wire rope is out of the groove when using the stage electric hoist with oil wire rope. Today, let me talk to you about this issue.
The small malfunction often encountered in the use of oil wire rope stage electric hoists is that the rope is out of groove, resulting in disorderly rope and other phenomena. So far, in order to avoid such problems and faults, most methods used are to install limit devices. The oil wire rope anti groove limit device of stage electric hoists is installed on the lifting hoist, and the fixing plate is connected to the side plate of the electric hoist drum; The two ends of the roller and roller shaped structure are connected to the fixed plate through a connecting rod, opposite to the drum and against the oil wire rope of the drum; One end of the spring is respectively connected to the two connecting rods, and the other end is fixed on the fixing plate;
The working contacts of the limit switch are fixed on the fixed plate, corresponding to the two connecting rods, and connected to the control circuit of the electric hoist through wires. They are connected in series to the up and down contactor circuits in the control circuit of the electric hoist, and the power supply of the control circuit is disconnected or closed. This utility model is designed to set a limit switch for the operation of the oil wire rope, in order to control the lifting motor of the electric hoist, and prevent the electric hoist from starting the lifting motor due to the hook head lifting and the oil wire rope not being subjected to force.
