The wire rope on the drum is used for oil injection.

The oil pump is a miniature adjustable plunger pump with a flow range of 0.15ml/min-500ml/min.

The designed oil supply time of the controller is once every two hours, and the oil supply amount is 2ml/h.

The connection method is welding or bonding.

The number of the several fuel injection nozzles is 16; the positions of the 16 fuel injection nozzles are adapted to the 16 circular grooves of the wire rope coiled on the drum of the CDQ hoist.

The working principle of the utility model is as follows: the controller circuit with the encoder is connected to the oil pump, and then the encoder designs the oil supply program (oil supply time and oil supply amount of the wire rope) to control the oil pump operation, and extract the oil tank during the design time period. The lubricating oil is sent to the fuel injection main pipe and the fuel injection nozzle through the oil pipeline, and the wire rope coiled on the hoist drum is sprayed with oil.

Beneficial effects of the utility model: The advantage of the utility model is that in the long-term high-load production of the CDQ hoist, the oil supply amount and oil supply time of the wire rope during the operation of the hoisting system are ensured by automatic oil supply, and the lubrication effect of the wire rope is ensured. , avoiding the uncertainty of manual refueling by operators, and realizing the purpose of stable operation of the CDQ lifting system.
