[0002] Wire rope is the traction rope used by cranes to lift heavy objects. Wire rope is a spiral bundle of steel wires twisted together according to certain rules. When the crane lifts heavy objects, the wire rope is subjected to tensile stress, and the compressive stress will squeeze out some grease. After a period of use, sludge will form on the surface of the wire rope, and at the same time, some wear debris produced by the wear of the wire rope will adhere to it, causing the wire rope to rust and aggravate the wear of the wire rope.

DETAILED DESCRIPTION

[0014] The following is a more detailed description of the steel wire rope lubrication mechanism for a gantry crane of the utility model in conjunction with the accompanying drawings and through specific implementation methods.

[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0016] See also Figure 1 The present embodiment is a wire rope lubrication mechanism for a gantry crane. The cleaning device uses a cleaning nozzle and a drying nozzle to rinse and dry the casting respectively. The wire rope lubrication mechanism uses an adjustable pulley block to adjust the height of the front end of the wire rope relative to the guide sleeve to facilitate scraping off dust on the wire rope. The oil brushes that rotate in opposite directions cooperate with the guide sleeve at the rear end of the wire rope to make the lubricant more evenly applied. It mainly includes a pulley block 3 and an oiling unit, and the pulley block 3 and the oiling unit are both arranged on the base plate 1.

[0017] One end of the pulley block 3 is hinged on the bracket 2, and the bracket 2 is fixedly connected to the end of the base 1. The other end is connected to the base plate 1 through an adjustment component. The adjustment component includes a sleeve 6, a screw 7 and an adjustment motor 8. The upper end of the sleeve 6 is hinged to the connecting frame 5 fixed on the pulley block 3, and the screw 7 is threadedly connected to the lower part of the sleeve 6. The screw 7 is powered by the adjustment motor 8. The lower end of the adjustment motor 8 is hinged on the base plate 1 to adjust the inclination angle of the pulley block.

[0018] The oiling unit includes an oil tank 9, an oil brush 11 and a driving assembly. A guide sleeve for the wire rope 20 is arranged on the side wall of the oil tank 9. The diameter of the guide sleeve is larger than the diameter of the wire rope 20. A soft pad is installed on the guide sleeve away from the pulley block 3. A cleaning cotton ring is arranged on the inner side of the soft pad to scrape off excess lubricating liquid on the wire rope. The oil brush 11 is arranged on both sides of the wire rope 20 and contacts the wire rope 20. The lower part of the oil brush 11 is immersed in the lubricating liquid 10 in the oil tank 9. The oil brush 11 is powered by the driving assembly.

[0019] The driving assembly includes a driving motor and a gear set, the gear set includes two mutually meshing first gears 18 and second gears 19, the oil brush 11 is a soft-bristle brush and its side contacts the upper part and the side of the wire rope 20, the oil brush 11 is installed on the rotating shaft, and the first pulley 12 and the second pulley 13 are respectively provided at the ends of the two rotating shafts, the first pulley 12 and the second pulley 13 are respectively connected to the third pulley 14 and the fourth pulley 15 through the first belt 16 and the second belt 17, the third pulley 14 is coaxial with the first gear 18 and is driven by the driving motor, and the fourth pulley 15 is coaxial with the second gear 19.

[0020] When in use, the wire rope passes around the pulley block and then passes through the front and rear guide sleeves in turn. At this time, the wire rope has not come into contact with the lubricating liquid in the oil tank. First, adjust the inclination angle of the pulley block using the adjusting motor according to the actual situation, start the driving motor, and drive the two sets of oil brushes to rotate from both sides to the middle to fully brush the lubricating liquid on the wire rope. The front guide sleeve is used to scrape off the dust attached to the wire rope, and the rear guide sleeve is used to scrape off the excess lubricating liquid on the wire rope, so that the lubricating liquid on the wire rope is applied more evenly.
