Description

Technical Field

[0001] This utility model relates to the field of lubrication technology, and in particular to a wire rope lubrication sleeve. Background Technology

[0002] Steel wire rope is a helical bundle of steel wires twisted together according to certain rules. It features high strength, high toughness, wear resistance, and impact resistance, and is widely used in hoisting, transportation, construction, mining, shipbuilding, fisheries, power, communications, and military fields. Frequent use leads to rapid wear of steel wire ropes, thus requiring long-term lubrication and maintenance. However, traditional steel wire rope lubrication methods rely primarily on manual application, which can result in uneven grease thickness. An excessively thick outer layer can attract dust, and high-altitude and deep-well operations require repeated climbing, leading to high labor costs and significant risks. Utility Model Content

[0020] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0021] Furthermore, it should be noted that the directional terms such as left, right, up, and down used in the embodiments of this utility model are only relative concepts or references to the normal use of the product, and should not be considered restrictive. The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] As attached Figure 1-3 The diagram shows a wire rope lubrication sleeve according to this utility model, comprising a housing 1, an oil inlet chamber 2 within the housing 1, oil collection chambers 3 forming at both ends of the oil inlet chamber 2 along its length, and an inlet / outlet chamber 4 extending to the surface of the housing 1 at the end of the oil collection chamber 3 away from the oil inlet chamber 2. The oil inlet chamber 2, oil collection chamber 3, and inlet / outlet chamber 4 are sequentially connected to each other to allow the wire rope to pass through. The centerlines of the oil inlet chamber 2, oil collection chamber 3, and inlet / outlet chamber 4 are located on the same straight line, facilitating the movement of the wire rope and reducing jamming.

[0023] The surface of the housing 1 has an oil inlet 5 communicating with the oil inlet chamber 2 and an oil outlet 6 communicating with the oil collection chamber 3. The oil inlet is connected to the automatic lubricator via an oil pipe, and the oil outlet 6 is connected to a waste grease collection bottle via an oil pipe. After the automatic lubricator is started, oil is injected into the oil inlet chamber 2 through the oil pipe from the oil inlet 5 until the oil storage volume of the oil inlet chamber 2 is 1 / 2 to 2 / 3 of its volume. After the oil storage volume of the oil inlet chamber 2 is sufficient, the wire rope can move up and down reciprocally. The part of the wire rope passing through the oil inlet chamber 2 will be coated with grease, and some grease will be scraped off and stored in the oil collection chamber 3 when passing through it. A spring brush 10 is installed in the inlet / outlet chamber 4. The wire rope passes through the center of the spring brush 10. If there are areas on the wire rope where the grease is not sufficiently coated, the spring brush 10 can evenly coat the area and scrape off some lumps of grease, making the grease distribution on the surface of the wire rope more uniform and improving the lubrication effect.

[0024] The side of the housing 1 has a viewing hole 7 that communicates with the oil inlet chamber 2 and the oil accumulation chamber 3 respectively. The viewing hole 7 is used to observe the amount of oil in the oil inlet chamber 2 and the oil accumulation chamber 3. A transparent viewing window 8 is installed on the surface of the housing 1 to cover the viewing hole 7. An O-ring 9 that is embedded in the housing 1 and surrounds the viewing hole 7 is installed between the viewing window 8 and the housing 1 to enhance the sealing performance and prevent grease leakage.

[0025] An oil drain channel is provided between the oil drain port 6 and the oil collection chamber 3. The oil drain channel includes a junction port 11 that communicates with the oil collection chamber 3. The junction port 11 is located at half the volume of the oil collection chamber 3, and the oil drain port 6 is lower than the junction port 11. When the wire rope moves up and down repeatedly for a long time, the grease in the oil collection chamber 3 will continuously accumulate. When the grease volume reaches nearly half the volume of the oil collection chamber 3, the grease will be discharged through the oil drain channel to the oil drain port 6, and finally enter the waste grease collection bottle for storage.

[0026] In this embodiment, the housing 1 includes a left half-shell and a right half-shell that fit together. The left half-shell and the right half-shell are connected by fasteners. Both ends of the left half-shell and the right half-shell are fitted with annular locking members 13 to keep them tightly fitted. A lifting ring 14 is installed on one side of the housing 1. A cavity is formed between the left half-shell and the right half-shell. Sealing rings 12 are installed at intervals in the cavity, dividing the cavity into an oil inlet cavity 2 and an oil collection cavity 3. The center of the sealing ring 12 has a sealing ring through hole 121. After the steel wire rope passes through the oil inlet cavity 2 and gets wrapped with grease, it passes through the sealing ring 12 to scrape off the grease. The scraped grease is stored in the oil collection cavity 3. More specifically, both the left and right halves of the shell include a shell body and spring brush halves connected to both ends of the shell body. The spring brush halves are connected to the shell body by fasteners. When the left and right halves of the shell are snapped together, the spring brush halves on the two shell bodies are also pressed tightly against each other. The inlet and outlet cavity 4 for placing the spring brush 10 is formed between the two pressed spring brush halves. The locking member 13 clamps the two spring brush halves together to prevent cracking.

[0027] As attached Figure 4 As shown, the sealing ring 12 is cylindrical, and a sealing ring groove 122 surrounding the sealing ring through hole 121 is formed on one end face of the sealing ring 12. The sealing ring groove 122 faces the oil inlet cavity 2. The width of the sealing ring groove 122 gradually decreases from the groove opening to the groove bottom, so that the part surrounding the sealing ring through hole 121 forms a conical structure. When the wire rope passes through the sealing ring through hole 121, the sealing ring groove 122 deforms slightly, and the sealing ring through hole 121 comes into contact with the wire rope, scraping off the oil on the surface of the wire rope. The structure of the sealing ring groove 122 allows the sealing ring through hole 121 to maintain a certain elasticity even after it is gradually worn, maintaining the oil scraping function and extending the service life. In addition, the presence of the sealing ring groove 122 increases the volume of the oil accumulation cavity 3 and enhances the oil storage function.

[0028] This utility model discloses a wire rope lubrication sleeve that moves the wire rope up and down repeatedly in the lubrication sleeve. This allows the wire rope to be coated with grease in the oil inlet chamber, some grease to be scraped off when passing through the oil collection chamber, and then evenly coated again when passing through the spring brush. This ensures that the grease is evenly applied to all parts of the wire rope, achieving sufficient lubrication and improving the lubrication effect.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
