[0039] Through the above configuration, when cleaning is performed, the crane lubrication maintenance equipment is provided with the power required for cleaning by the motor 604, and the active pulley 602 and the driven pulley 603 cooperate with each other to drive the grinding belt 601 to rotate, so that the lower surface of the grinding belt 601 contacts the crane wire rope, thereby cleaning the rust spots on the surface of the crane wire rope. At the same time, the operator can use the control valve 104 to conduct the connecting pipe 2 to open the nozzle 301 under the grinding belt 601 to spray lubricant on the cleaned surface of the wire rope.

[0040] In a preferred embodiment of the present invention, the mounting frame 501 is a rectangular frame structure. The mounting frame 501 is made of steel, so that the mounting frame 501 can provide sufficient support to ensure the stability of the cleaning assembly 6 during operation.

[0041] In a preferred embodiment of the utility model, the lubrication maintenance equipment for the crane further includes an adjusting rod 102 and a transmission frame 103.

One end of the transmission frame 103 is rotatably connected to the end of the adjusting rod 102, for example, the one end of the transmission frame 103 is rotatably connected to the end (for example, the front end) of the adjusting rod 102 through a pin. The other end of the transmission frame 103 is rotatably connected to the control valve 104, for example, the other end of the transmission frame 103 is rotatably connected to the control valve 104 through a pin. The lubricant storage tank 1 is filled with a wire rope lubricant (wire rope lubricant). The wire rope lubricant can be a conventional wire rope lubricant, for example, the wire rope lubricant can mainly include synthetic oil or mineral oil, a thickener, a high lubricity nanomaterial, and a variety of additives. When the lubricant is sprayed with the nozzle 301, the adjustment lever 102 is manually pressed, and the transmission frame 103 drives the control valve 104 to be in an open state, so that the wire rope lubricant reaches the installation pipe 3 through the connecting pipe 2, and is sprayed out by the nozzle 301 to adhere to the surface of the wire rope of the crane.

[0042] In a preferred embodiment of the present invention, a base 101 is fixedly mounted on the bottom of the lubricant storage tank 1 to enhance the stability of the overall structure of the device.
