Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary equipment technology for lifting machinery, specifically a wire rope lubrication device for lifting machinery. Background Technology
[0002] Wire rope is a crucial component of lifting machinery. Due to its frequent use, its daily maintenance is extremely important. Regular lubrication not only reduces the coefficient of friction and wear but also prevents performance degradation due to corrosion. Currently, wire rope lubrication is mainly performed manually, using methods such as brushing, spraying, and immersion. Brushing involves operators manually applying lubricant (paste or oil) to the wire rope surface with a brush; this method suffers from low efficiency and uneven application. Spraying involves operators using a spray bottle or spraying equipment to spray oily lubricant onto the wire rope surface; this method suffers from poor penetration and waste. Immersion involves disassembling the wire rope and immersing it in lubricant to allow for full absorption; this method is time-consuming, labor-intensive, and can disrupt construction progress.
[0003] Based on this, a lubrication device for wire ropes of lifting machinery is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0022] In one embodiment, such as Figure 1 and Figure 2 As shown, a wire rope lubrication device for lifting machinery includes a base 1 fitted onto the wire rope 11 to be lubricated. The base 1 is assembled from two semi-circular structures. Connecting components are provided at both ends of the base 1, and a fixing ear plate 10 is provided at one end of the base 1. Four lubrication components 5 are symmetrically arranged inside the base 1. The lubrication components 5 are rotatably installed inside the base 1. An adjusting component is provided at the lower end of the lubrication component 5, and a locking component is provided on one side of the lubrication component 5. In use, the base 1 is installed on the wire rope 11 to be lubricated and fixed by the connecting components. Then, the base 1 is fixed to the crane by the fixing ear plate 10. Next, the adjusting component is used to make the lubrication component 5 fit against the surface of the wire rope 11 to be lubricated, and then it is locked by the locking component. Then, the crane is controlled to rewind the wire rope 11 to be lubricated, so that the wire rope passes through the lubrication component 5, thereby making the lubricating oil evenly applied to the surface of the wire rope.
[0023] In one embodiment, such as Figure 2 As shown, the adjustment assembly includes a gear ring 2 rotatably connected to the inner side of the base 1 and a gear 3 disposed at the lower end of the lubrication assembly 5. The gear 3 is provided with a rotating shaft 4, the lower end of which is rotatably connected to the base 1. The gear 3 meshes with the gear ring 2. In use, by rotating the gear ring 2, the lubrication assembly 5 is driven to rotate through the gear 3, thereby causing the oil outlet of the lubrication assembly 5 to come into contact with the surface of the wire rope 11 to be lubricated.
[0024] In one embodiment, such as Figure 2 As shown, the locking assembly includes a screw 6 that penetrates the side wall of the base 1. One end of the screw 6 is provided with a first locking nut 7, which is rotatably connected to the base 1. When the lubrication assembly 5 is adjusted to a suitable position, the screw 6 applies pressure to the lubrication assembly 5 by tightening the first locking nut 7, thereby fixing the lubrication assembly 5 in the current position and preventing position displacement due to external force during lubrication, thus ensuring the stability and uniformity of lubrication.
[0025] In one embodiment, such as Figure 2 As shown, the connecting assembly includes a locking bolt 8 and a second locking nut 9. Both the locking bolt 8 and the second locking nut 9 are located at both ends of the base 1. During installation, the two semi-circular bases 1 are installed on the steel wire rope 11 to be lubricated, and then fixedly connected by the locking bolt 8 and the second locking nut 9.
[0026] In one embodiment, such as Figure 3As shown, the lubrication assembly 5 includes an oil tank 52, an installation hole 51 on one side of the oil tank 52, an oil tank cover 53 at the upper end of the oil tank 52, an oil inlet 54 on the oil tank cover 53, an oil delivery tube 55 on one side of the oil tank 52, and an application assembly on one side of the oil delivery tube 55. Lubricating oil is added into the oil tank 52 through the oil inlet 54, and then transported to the application assembly through the oil delivery tube 55. Finally, the application assembly evenly applies the lubricating oil to the surface of the wire rope, thus completing the lubrication process.
[0027] In one embodiment, such as Figure 3 As shown, the coating assembly includes a lubricating ball head 56 disposed on the oil outlet side of the oil supply capillary tube 55. A fixing cover plate 57 is provided on one side of the lubricating ball head 56, and the fixing cover plate 57 is fixed to the outside of the oil tank 52. Rolling balls 58 are evenly distributed between the lubricating ball head 56 and the outer wall of the oil tank 52. When the lubricating oil flows out from the oil supply capillary tube 55, it will enter the lubricating ball head 56. As the wire rope moves, the lubricating ball head 56 contacts the surface of the wire rope and rolls. The setting of the rolling balls 58 reduces the friction between the lubricating ball head 56 and the outer wall of the oil tank 52, so that the lubricating ball head 56 can rotate more flexibly, thereby applying the lubricating oil more evenly to the surface of the wire rope and improving the lubrication effect.
[0028] In one embodiment, such as Figure 2 As shown, the upper end of the rotating shaft 4 is fixedly installed in the mounting hole 51. When the gear 3 rotates, the oil tank 52 is driven to rotate together through the rotating shaft 4.
[0029] In one embodiment, such as Figure 2 As shown, a rubber gasket is provided at one end of the screw 6 located inside the base 1. The rubber gasket protects the oil tank 52 and prevents the screw 6 from damaging the oil tank 52.
[0030] The above embodiment discloses a wire rope lubrication device for lifting machinery. In use, the base 1 is installed on the wire rope 11 to be lubricated and fixed by the locking bolt 8 and the second locking nut 9. Then, the base 1 is fixed to the crane by the fixing ear plate 10. Next, the gear ring 2 is rotated, and at the same time, the gear 3 drives the lubrication component 5 to rotate, so that the lubrication component 5 is in contact with the surface of the wire rope 11 to be lubricated. Then, the first locking nut 7 is tightened, so that the screw 6 applies pressure to the lubrication component 5, thereby fixing the lubrication component 5 in the current position. Then, the crane is controlled to rewind the wire rope 11 to be lubricated. As the wire rope moves, the lubrication ball head 56 contacts the surface of the wire rope and rolls. The setting of the ball 58 reduces the friction between the lubrication ball head 56 and the outer wall of the oil tank 52, so that the lubrication ball head 56 can rotate more flexibly, thereby spreading the lubricating oil more evenly on the surface of the wire rope.
[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
