[0002] For the steel wire rope, one of the important parts of cranes and winches, its mechanical properties and geometric dimensions meet the requirements. The steel wire rope is composed of steel wire, rope core and grease. During the production and manufacturing, the steel wire rope will be twisted together into a spiral steel wire bundle according to certain rules. When twisting the strands, grease is sprayed in front of the strands closing point. The combined effect of grease and phosphating film prevents the occurrence of fretting wear of the steel wire rope and prolongs its service life. Therefore, the oiling of the steel wire rope is essential.

[0003] At present, the inventors have found that in the existing technology, the grease coating on the wire rope is usually applied at a single point, and then the wire rope is coated with a brush reciprocatingly. This method makes the manual labor intensity high and easily leads to uneven coating, thereby reducing the coating efficiency.

[0004] Therefore, based on the above problems, we designed a grease coating component. Utility Model Content

[0029] like Figures 1 to 3 As shown, in this embodiment, a pair of wire rope guide wheels 2 are further provided, and the pair of wire rope guide wheels 2 are respectively rotatably provided on the machine rod 11, and a pair of gears 21 meshing together are provided on the back of the machine rod 11, and each gear 21 is respectively connected to each wire rope guide wheel 2;

[0030] Specifically, each wire rope guide wheel 2 is concave in design, and the gear 21 is driven by a servo motor externally mounted on the machine rod 11. The main shaft of the servo motor is connected to one of the gears 21. When installed and used, the wire rope to be coated is introduced into the two upper and lower wire rope guide wheels 2, and then the servo motor drives a pair of gears 21 to rotate, so that a pair of upper and lower distributed wire rope guide wheels 2 rotate in the same direction to guide the wire rope in a limited direction, which can prevent deviation during the coating process and further improve the coating effect.

In addition, it should be noted that the push cylinder 32 and the servo motor are commercially available products of the prior art, and the working principle has been made public. Before implementation, select the appropriate product model for installation. This application document only targets the existing grease coating of the wire rope. The wire rope is often coated with a single point, and then coated with a brush in a reciprocating manner.

[0033] When the wire rope is transmitted, the end of the wire rope is allowed to enter from the port of the coating ring 41 on one side of the coating channel 4, so that the cylinder 32 is pushed to provide power to drive the pressure extrusion piston 33 to move downward, so that the grease in the grease storage tank 3 is squeezed into the grease injection tube 31 under the action of pressure, and then enters the inner cavity 411 of the coating ring 41 through the other end port of the grease injection tube 31, and then is introduced into the wire rope to be coated from several grease outlets 412, so as to achieve comprehensive coating of the wire rope. At this time, it is scraped and flattened by the scraper ring 42 on the other side of the coating channel 4 and then transported out, so that excess grease is scraped off and left in the coating channel 4, which is convenient for cleaning after removing the coating ring 41 and the scraper ring 42 later. The design of the utility model does not require manual reciprocating coating, reduces the labor intensity burden of manual labor, and allows the grease to be applied more evenly, thereby improving the coating efficiency.
