Description

Technical Field

[0001] The utility model is applied to the technical field of steel wire rope lubrication, and particularly relates to an online lubrication device for a hoist steel wire rope. Background Art

[0002] Wire rope is an important equipment in engineering machinery. In the process of industrial production, large equipment is needed to carry and transfer products. During the transportation process, due to the heavy weight of the raw materials of the products, wire ropes with high hardness and strong toughness are usually used to pull the products. During the long-term use of wire ropes, metal fatigue or wear will occur in the wire ropes under different forces and different environments. The general use damage of wire ropes is manifested as wear, fatigue and corrosion of the wire ropes. Especially in ports, mines, coal mines and other areas, wire ropes are in relatively harsh environments with humid air and high dust, which causes corrosion of the wire ropes. At this time, the wire ropes need to be lubricated and maintained to make the force between the steel wires of the wire ropes uniform, increase the service life of the wire ropes, and avoid accidents caused by wire rope jamming or breakage.

[0003] In the prior art, wire ropes are primarily lubricated by hand or by oil spraying. Due to long-term lubrication, wire ropes are prone to breakage, posing a potential risk to construction workers. Furthermore, the oil is unevenly distributed. Traditional lubrication methods involve applying oil to the surface of the wire rope, but this makes it difficult to ensure complete wetting of the interior of the wire rope. Furthermore, the oil easily drips, wasting lubricant and polluting the environment, posing a significant safety hazard. Alternatively, lubricant can be applied by dripping it onto the surface of the wire rope using an oil dripping device. This method can avoid the safety hazards associated with manual lubrication, but the dripping process can lead to issues such as inaccurate dripping locations and uneven dripping amounts. This results in uneven lubricant application on the wire rope, making it more susceptible to wear, fatigue, and corrosion. The aforementioned problems could be addressed by designing an automatic lubricating device for lubricating wire ropes that is simple in structure, easy to install, and capable of completely immersing and evenly coating the lubricant in the lubricant while also being less susceptible to lubricant leakage and contamination.

[0004] For example, Chinese patent publication number CN116639615A discloses an automatic lubrication device for a winch wire rope. The device inserts one end of a steel cable into the inner wall of a lubrication drum, and lubricating oil is added to the inner wall of an oil storage tank. A rotary motor is then activated, causing the rotary motor to rotate a rotating rod and a reel. The reel rotates to release the steel cable wound on the reel. As the steel cable is released, the outer wall of the steel cable continuously passes through the inner wall of the lubrication drum. The cylindrical shape of the lubrication drum facilitates the passage of the steel cable. As the steel cable passes through the inner wall of the lubrication drum, a first valve is rotated to open, allowing the lubricating oil in the oil storage tank to move downward. The degree of opening of the first valve can be adjusted as needed, thereby facilitating control of the amount of lubricating oil that enters the lubrication drum. While this solves the problem of workers manually adding lubricating oil to the steel cable, it is difficult to fully lubricate the steel cable, and the lubrication area of ​​the steel cable is limited.

[0005] Therefore, it is necessary to provide an online lubrication device for hoist wire rope, which has a simple structure, is easy to install, can make the wire rope completely immersed in lubricating grease, achieve uniform coating of the wire rope, and prevent lubricant leakage.

[0024] like Figures 1 to 6As shown, in this embodiment, the utility model includes a guide plate 14, and the guide plate 14 is slidably provided with a slider 15, and the slider 15 is connected to an oiling module 19, and the oiling module 19 includes a first rope clamp 1 and a second rope clamp 2 that are sealed together, and one side of the first rope clamp 1 is hinged to one side of the second rope clamp 2, and the inner side of the first rope clamp 1 and the inner side of the second rope clamp 2 are respectively provided with a first oil storage tank 3 and a second oil storage tank 4, and the side edges of the first oil storage tank 3 and the side edges of the second oil storage tank 4 are both provided with oil scrapers, and the steel wire rope 9 to be lubricated passes through the oil storage tanks and the oil scrapers in turn.

[0025] When the first rope clamp 1 and the second rope clamp 2 are folded, the first oil storage tank 3 and the second oil storage tank 4 form a lubricating oil chamber, and the steel wire rope 9 to be lubricated passes through the seal 6, the brush 5, the lubricating oil chamber, the brush 5, and the seal 6 in sequence. When the hoist reels the steel wire rope 9 to be lubricated, the steel wire rope 9 to be lubricated slides axially, and the lubricating grease in the lubricating oil chamber lubricates and maintains the steel wire rope 9 to be lubricated, ensuring that the steel wire rope 9 to be lubricated can be completely immersed in the lubricating oil chamber. The oil scraper scrapes off excess lubricating grease from the steel wire rope 9 to be lubricated, and the steel wire rope 9 to be lubricated is evenly coated to prevent waste of lubricating grease and avoid leakage of lubricating grease to pollute the environment, thereby realizing automatic cleaning and lubrication of the steel wire rope 9 to be lubricated. The slider 15 is slidably arranged on the guide plate 14, and the position of the slider 15 on the guide plate 14 is adjusted according to the position of the steel wire rope 9 to be lubricated.

[0026] like Figures 1 to 3 As shown, in this embodiment, the oil scraper includes a brush 5 and an inner ring 18, and the brush 5 and the inner ring 18 are symmetrically arranged on the left and right sides of the first oil storage tank 3 and the left and right sides of the second oil storage tank 4, respectively. The through hole of the inner ring 18 is adapted to the outer diameter of the steel wire rope 9 to be lubricated, and the steel wire rope 9 to be lubricated passes through the brush 5, the oil storage tank, and the inner ring 18 in sequence.

[0027] By combining the brush 5 and the inner ring 18, the brush 5 evenly coats the steel wire rope 9 to be lubricated, and the inner ring 18 scrapes off excess grease from the steel wire rope 9 to be lubricated, thereby reducing the amount of oil between strands, and the intercepted grease flows back to the lubricating oil chamber to prevent waste. When the steel wire rope 9 to be lubricated is axially raised or lowered, the grease in the lubricating oil chamber lubricates the steel wire rope 9 to be lubricated, and under the action of the pressure, the brush 5 evenly coats the steel wire rope 9 with the lubricating oil chamber, ensuring that the lubricating oil chamber coats the surface of the steel wire rope 9 to be lubricated and the gaps between strands. The inner ring 18 can completely intercept the excess grease from the steel wire rope 9 to be lubricated, thereby reducing the amount of oil between strands, and the intercepted grease flows back to the lubricating oil chamber to prevent waste.

The handles of the first rope clamp 1 and the second rope clamp 2 are symmetrically arranged. A bracket 16 is connected to the top of the slider 15. Mounting holes 17 are provided at the corners of the first rope clamp 1 and the second rope clamp 2. The bracket 16 is hingedly connected to one of the mounting holes 17. The handles 10 facilitate the opening and closing of the device, the replacement of parts, and the on-site transportation of the wire rope lubricator to be lubricated.

[0036] like Figures 1 to 6 As shown, in this embodiment, U-shaped mounting grooves 11 are formed on both the left and right sides of the handle 10. The U-shaped mounting grooves of the first rope clamp 1 and the second rope clamp 2 are symmetrical in vertical direction.
