Description

Technical Field

[0001] This utility model relates to the field of advanced manufacturing and automation technology, specifically to a wire rope lubrication device for lifting machinery. Background Technology

[0002] Lifting machinery uses a lifting hook or other lifting device to lift or move heavy objects. The working process of lifting machinery generally includes steps such as lifting, running, lowering and returning to the original position. The lifting mechanism lifts the heavy object from the lifting location through the lifting device, moves the heavy object through the running, slewing or luffing mechanism, lowers the heavy object to the designated location and then returns to the original position.

[0003] In the field of lifting machinery, wire ropes are key components for bearing and transmitting weight, and their performance stability and durability directly affect the safety and efficiency of lifting operations. However, during use, wire ropes can experience performance degradation due to factors such as friction, wear, and corrosion, potentially leading to safety accidents. Therefore, regular lubrication and maintenance of wire ropes are of paramount importance.

[0004] Traditional wire rope lubrication methods mostly involve manually applying or spraying lubricant. This method is not only inefficient, but also makes it difficult to ensure that the lubricant is evenly applied to the wire rope, thus affecting the lubrication effect. At the same time, manual lubrication also poses safety hazards, because the wire rope is usually in a high-speed state when the lifting machinery is working, and it is very easy to cause accidents when a person approaches to perform lubrication. Therefore, it is necessary to design a wire rope lubrication device for lifting machinery. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1:

[0026] A preferred embodiment of the wire rope lubrication device for lifting machinery provided by this utility model is, for example... Figure 1-5 As shown: A wire rope lubrication device for lifting machinery includes a base 1, a protective box 2 fixedly installed on the top of the base 1, an installation hole on the outer wall of the protective box 2, and an observation transparent window 3 fixedly installed on the inner wall of the installation hole, a controller 4 fixedly installed on one side of the outer wall of the protective box 2, a rope inlet 5 on one side of the outer wall of the protective box 2, and a rope outlet 6 on the other side of the outer wall of the protective box 2; a limiting lubrication assembly 7, which is disposed inside and outside the protective box 2; the limiting lubrication assembly 7 includes: a limiting part 71, which is disposed on the outside of the protective box 2; and a lubrication part 72, which is disposed inside the protective box 2 and on one side of the limiting part 71.

[0027] The limiting part 71 includes: a ring groove 711, which is formed on the outer wall of the protective box 2; a ring bar 712 is slidably connected inside the ring groove 711, and a rotating disk 713 is fixedly installed on the outer wall of the ring bar 712. Arc-shaped grooves 714 are equidistantly formed on the outer circumference of the rotating disk 713.

[0028] The arc-shaped slide groove 714 is internally connected to a connecting rod 715, and the other end of the connecting rod 715 is fixedly connected to an installation block 716. The outer wall of the installation block 716 is fixedly installed with a limit clamping block 717.

[0029] Furthermore, this embodiment provides a stable and flexible sliding track for the rotating disc 713 and its arc-shaped sliding groove 714 by setting an annular sliding groove 711 and an annular bar 712. This allows the connecting rod 715, mounting block 716, and limiting clamping block 717 to move smoothly along the arc-shaped sliding groove 714. Driven by the telescopic cylinder 718, the wire rope is precisely limited and clamped, ensuring the stability of the wire rope during the lubrication process and enabling the limiting of wire ropes of different diameters.

[0030] Example 2:

[0031] Based on Embodiment 1, a preferred embodiment of the wire rope lubrication device for lifting machinery provided by this utility model is as follows: Figure 1-5 As shown: the lubrication part 72 includes: a mounting plate 721, which is fixedly installed on the inner wall of one side of the protective box 2, and there are four sets of the mounting plate 721; the outer wall of the mounting plate 721 is provided with a sliding hole 722, and an L-shaped sliding plate 723 is slidably connected inside the sliding hole 722; an arc-shaped plate 724 is fixedly installed on the outer wall of the L-shaped sliding plate 723, and there are four sets of the arc-shaped plate 724.

[0032] The bottom of the arc-shaped long plate 724 is provided with an installation groove 725. The interior of the installation groove 725 is provided with a rotating wheel 726 through a connecting shaft. The other outer wall of the arc-shaped long plate 724 is fixedly connected to an installation plate 727, and the installation plate 727 is fixedly installed on the other inner wall of the protective box 2.

[0033] A connecting bracket 728 is fixedly installed on the outer wall of the mounting plate 727, and the connecting bracket 728 is located above the arc-shaped long plate 724. The top of the connecting bracket 728 has a mounting hole, and a lubricating oil box 729 is fixedly installed on the inner wall of the mounting hole. A replenishment pipe 7210 is connected to the top of the lubricating oil box 729, and the replenishment pipe 7210 movably passes through the top of the protective box 2 and extends to the top of the protective box 2.

[0034] A U-shaped support frame 7211 is fixedly installed at the bottom of the connecting frame 728. An installation groove is opened at the bottom of the inner wall of the U-shaped support frame 7211, and a connecting horizontal pipe 7212 is fixedly installed inside the installation groove. A delivery pump is installed inside the lubricating oil box 729, and a connecting vertical pipe 7213 is connected to one side of the delivery pump. The connecting vertical pipe 7213 movably passes through the bottom of the lubricating oil box 729 and extends into the interior of the connecting horizontal pipe 7212.

[0035] Oil dripping tubes 7214 are evenly and uniformly connected to the bottom of the connecting horizontal tube 7212. An elongated hole 7215 is provided below the oil dripping tube 7214. The elongated hole 7215 is opened at the top of the arc-shaped long plate 724 and extends into the interior of the mounting groove 725.

[0036] Furthermore, this embodiment incorporates an installation plate 721, a sliding hole 722, an L-shaped sliding plate 723, an arc-shaped plate 724, and a rotating wheel 726, ensuring smooth passage of the wire rope. Simultaneously, the connecting shaft within the installation groove 725 ensures flexible rotation of the rotating wheel. Combined with the connecting frame 728, lubricating oil box 729, connecting horizontal pipe 7212, connecting vertical pipe 7213, dripping oil pipe 7214, and elongated hole 7215, the dripping lubricating oil can directly penetrate into the installation groove 725, continuously and evenly adding lubricating oil to the wire rope. This ensures sufficient lubrication even during high-speed operation, thereby extending its service life and reducing wear and malfunctions.

[0037] In use, firstly, the operator turns on the power via controller 4. After the device starts, the steel wire rope enters the protective box 2 through the rope inlet 5. Then, the limiting part 71 starts working, and the telescopic cylinder 718 drives the connecting rod 715 to slide within the arc-shaped groove 714. Since the arc-shaped groove 714 is equidistantly located on the outer circumference of the rotating disc 713, the sliding of the connecting rod 715 will cause the mounting block 716 and its limiting clamping block 717 to move along the arc-shaped path, thereby achieving the movement of the steel wire rope. The clamping and limiting of the wire rope allows the limiting clamping block 717 to adapt to wire ropes of different diameters, ensuring its stability during lubrication. Furthermore, the lubrication unit 72 also begins operation. Lubricating oil in the lubrication oil box 729, under the action of the delivery pump, is transported through the connecting vertical pipe 7213 to the connecting horizontal pipe 7212. The evenly connected dripping capillary 7214 at the bottom of the connecting horizontal pipe 7212 evenly drips the lubricating oil onto the wire rope. Because the dripping capillary 7214 is located below... An elongated hole 7215 is provided, which is located at the top of the arc-shaped long plate 724 and extends into the interior of the mounting groove 725. Therefore, the dripping lubricating oil can directly penetrate into the contact surface between the wire rope and the rotating wheel 726, achieving sufficient lubrication. Furthermore, the sliding connection of the L-shaped sliding plate 723 within the sliding hole 722 allows the arc-shaped long plate 724 and the rotating wheel 726 on it to be finely adjusted as needed to accommodate wire ropes of different diameters. In addition, throughout the lubrication process, the user can observe the lubrication status of the wire rope in real time through the observation window 3, and adjust parameters such as the extension and retraction of the telescopic cylinder 718 and the delivery speed of the delivery pump through the controller 4 as needed to achieve the best lubrication effect. When the lubricating oil in the lubricating oil box 729 is insufficient, the user can add lubricating oil to the lubricating oil box 729 through the replenishment pipe 7210 to ensure the continuous and stable operation of the lubrication system. Finally, the fully lubricated wire rope leaves the protective box 2 from the rope outlet 6.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
