The utility model relates to a steel wire rope cleaning and lubricating device, which comprises a support. An oil cavity and a sealing cavity are arranged in the support, a steel wire rope penetrates through the oil cavity and the sealing cavity, a sealing bush matching with the steel wire rope is disposed in the sealing cavity, the oil cavity is connected with a high-pressure oil pump via a pipeline, when the steel wire rope penetrates through the oil cavity, lubricating oil in the oil cavity not only can lubricate the surface of the steel wire rope, but also can permeate into the steel wire rope under action of pressure so as to lubricate the inside of the steel wire rope, and is fine in lubricating effect, oil supply quantity of the lubricating oil in the sealed oil cavity can be controlled according to needs, leakage of the lubricating oil can be avoided, environmental pollution and waste of the lubricating oil are avoided, and guiding bushings are respectively arranged on a steel wire rope inlet side and a steel wire rope outlet side of the support and can limit movement trace of the steel wire rope, so that the steel wire rope and the sealing bush are squeezed together and located at ideal positions. The steel wire rope cleaning and lubricating device is fine in sealing effect, and the service life of the sealing bush can be prolonged.
