Description

Technical Field

[0001] This invention relates to the field of steel cable maintenance technology, specifically to a device for applying grease to the strands of steel cables. Background Technology

[0002] A wire rope is a helical bundle of steel wires that meet specific mechanical and geometric requirements, twisted together according to certain rules. It consists of steel wires, a core, and lubricant. The process involves first twisting multiple layers of steel wires into strands, then winding a certain number of strands around the core to form a helical shape.

[0003] Many shipyards choose manual lubrication for the wire ropes used in their lifting equipment. However, this method of manually brushing grease onto the wire rope surface results in uneven application. Excessive application can cause dripping and falling grease from heights, posing a danger. Large chunks of grease falling as they pass over pulleys can also severely contaminate imported steel plates awaiting processing below the lifting equipment, potentially rendering them unusable. Insufficient lubrication leads to poor maintenance. Some opt for specialized maintenance devices, but these are typically made of rigid nylon or polyurethane materials with a fixed, non-adjustable diameter. This creates significant friction on the wire rope, resulting in poor maintenance and further grease loss. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned technical difficulties and provide a grease application device for steel cable strands that can uniformly apply grease without causing grease dripping and has a better maintenance effect.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: a grease-coating device for steel cable strands, comprising an upper grease injection module body and a lower grease injection module body that cooperate and connect together. Oil cavities are respectively opened on opposite sides of the heads of the upper and lower grease injection module bodies. Cover plates are respectively installed on opposite sides of the heads of the upper and lower grease injection module bodies. Oil inlet holes communicating with the oil cavities are opened on the cover plates. Oil outlet holes are opened on the left inner wall of the oil cavities. A push piston is provided inside the oil cavities. Tile movable grooves communicating with the oil cavities are respectively opened on opposite sides of the heads of the upper and lower grease injection module bodies. The tile movable groove is provided with a silicone-coated tile connected to the push piston on the same side. The upper oil injection module body and the lower oil injection module body are respectively provided with oiling chambers connected to the tile movable groove on opposite sides of the middle part. The front end and rear end of the opposite sides of the upper oil injection module body and the lower oil injection module body are respectively provided with wire rope half holes. The opposite sides of the tail of the upper oil injection module body and the lower oil injection module body are respectively provided with oil return holes. The inner wall of the front part of the oiling chamber is provided with several oiling holes connected to the oil return holes on the same side. The oil return holes are connected to the oil outlet holes on the same side through oil return hoses. The bottom inner wall of the lower oiling chamber is provided with an oil drain hole.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] A device for applying grease to the seams of steel cable strands includes an upper grease injection module body 1 and a lower grease injection module body 2 that are fitted together and connected. The left side of the upper grease injection module body 1 and the left side of the lower grease injection module body 2 are hinged together. Oil chambers 4 are respectively opened on opposite sides of the heads of the upper grease injection module body 1 and the lower grease injection module body 2. Cover plates 13 are respectively installed on opposite sides of the heads of the upper grease injection module body 1 and the lower grease injection module body 2, and are respectively fixed to the upper grease injection module body 1 and the lower grease injection module body 2 by screws. The cover plates 13 have oil inlet holes 3 that communicate with the oil chambers 4. Oil outlet holes 5 are opened on the inner wall of the left side of the oil chambers 4. A push piston 6 is provided in the oil chambers 4. Tile movable grooves 7 that communicate with the oil chambers 4 are respectively opened on opposite sides of the heads of the upper grease injection module body 1 and the lower grease injection module body 2. The tile movable grooves 7 are provided with push pistons 6 on the same side. The connected silicone-coated tiles 8, the upper oil injection module body 1 and the lower oil injection module body 2 respectively have oiling chambers 9 on opposite sides of the middle part, which are connected to the tile movable grooves 7. The front and rear ends of the opposite sides of the upper oil injection module body 1 and the lower oil injection module body 2 respectively have wire rope half holes 10. The two wire rope half holes 10 on the same side cooperate to form a complete wire rope round hole. The radius of the wire rope round hole is relatively large. The radius of the general steel cable is smaller than its radius, so the wire rope round hole can allow steel cables of various specifications to pass through. The opposite sides of the tail of the upper oil injection module body 1 and the lower oil injection module body 2 respectively have oil return holes 11. The inner wall of the front part of the oiling chamber 9 has several oiling holes 12 that are connected to the oil return holes 11 on the same side. The oil return holes 11 are connected to the oil outlet holes 5 on the same side through oil return hoses. The bottom inner wall of the lower oiling chamber 9 has an oil drain hole 14.

[0023] The left front and rear sections of the upper oil injection module body 1 and the left front and rear sections of the lower oil injection module body 2 are hinged together, and the right front and rear sections of the upper oil injection module body 1 and the right front and rear sections of the lower oil injection module body 2 are fastened together. There are three oiling holes 12 within the same oiling cavity 9, evenly distributed around the circumference of the oiling cavity 9. Oil pipe connectors are provided on the oil inlet hole 3, oil outlet hole 5, oil return hole 11, and oil drain hole 14, allowing for faster and more convenient connection to the oil delivery hose.

[0024] In a specific implementation of this invention, the upper oil injection module body 1 and the lower oil injection module body 2 are opened and fitted onto the steel cable, allowing the steel cable to pass through each wire rope half-hole 10 and the oiling chamber 9. Then, oil is injected into the oil chamber 4 through the oil inlet 3. As the amount of oil in the oil chamber 4 increases, the two push pistons 6 will respond to the oil pressure until two silicone rubber sheets 8 are clamped on the steel cable (the silicone rubber sheets 8 have less friction on the steel cable, resulting in better maintenance). Then, the oil in the oil chamber 4 is discharged from the oil outlet 5 and flows back into the oiling chamber 9 through the oil return hole 11 and the oiling hole 12, filling the strand gaps of the steel cable. Then, the steel cable is continuously fed backward, and the oil is continuously filled into the strand gaps of the steel cable. Excess oil will be discharged from the oil drain hole 14.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
