It is a self-protection and traction device for vehicles and ships. Among them, the winches on ships can be divided into four types according to their driving methods: manual winches, electric winches, pneumatic winches, and hydraulic winches. The ropes they use are all steel cables.

[0003] During actual use, the steel cable is easily affected by friction, stretching or twisting, which may cause increased surface wear and tear, thus affecting the service life of the steel cable. In addition, it is also very susceptible to corrosion, so it is necessary to regularly apply lubricant to the steel cable on the winch.

[0004] The existing coating methods are mostly manual coating, which is not only cumbersome, time-consuming and labor-intensive, but also easily affected by the installation position of the winch. For example, a winch installed at a higher position on the hull requires workers to carry out construction at a high place, so it is very inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0027] Combination Figure 1-5 As shown, an anti-corrosion device for a marine cable winch comprises:

[0028] The base 1 is the installation base of the entire device, and its overall structure is annular and hollow inside;

[0029] The cylinder 2 is vertically arranged at the center of the base 1 and is rotatably connected to the base 1. A through hole of the same size as the center of the base 1 is provided inside, and the steel cable vertically passes through the through hole;

[0030] The protective shell 3 is sleeved on the outside of the cylinder 2 and is rotatably connected to the cylinder 2 through a bearing structure, and the bottom of the protective shell 3 is fixedly connected to the base 1, and a certain distance should be reserved between the protective shell 3 and the cylinder 2;

[0031] The oiling assembly 4 is arranged inside the cylinder 2 and is used to apply lubricant to the surface of the steel cable passing through the cylinder 2.

[0032] Specifically, in the present embodiment, four openings 21 are provided on the side wall of the cylinder 2, each opening 21 is configured as a rectangular structure and a groove is provided on the side wall surface thereof, and the four openings 21 are arranged in a circular array.

[0033] The oiling component 4 includes a slider 41 arranged on the opening 21. The slider 41 is overall arranged in a rectangular shape, and its side wall is partially protruded outward so as to be movably assembled with the groove on the side wall of the opening 21. In addition, a brushing member 42 is also provided on the inward side of the slider 41. The brushing member 42 can be set as a brush, and the two ends of the end face should be protruded so that the area where the brushing member 42 is installed shrinks inward.

[0034] A plurality of fine holes are provided on the central side of the slider 41, and the fine holes are arranged alternately with the bristles on the brush member 42. At the same time, the interior of the slider 41 is arranged to be hollow, and an oil delivery pipe 43 is provided on the top surface thereof to communicate with the slider 41. An oil filling ring 45 is fixedly connected to the side wall of the cylinder 2 to make its interior hollow, and an annular bottom plate 46 is rotatably mounted on the bottom surface of the oil filling ring 45, and a valve port is provided at the bottom end of the bottom plate 46, which extends downward to the bottom surface of the base 1, and a ball bearing is provided at the connection between the oil filling ring 45 and the bottom plate 46, and sealing gaskets are provided on both sides of the ball bearing.

[0035] An oil storage tank 5 is also arranged below the base 1. The delivery pipeline on the top of the oil storage tank 5 is connected to the valve port, and a hydraulic pump 51 is provided at the connection, so that the lubricating oil stored in the oil storage tank 5 can be smoothly delivered to the inside of the oil filling ring 45, and then delivered to the inside of the slider 41 through the oil delivery pipe 43, and seeps onto the brush through the fine holes on its side wall, and is smeared on the surface of the steel cable to complete the lubrication and anti-corrosion work.

[0036] In the above structure, in order to achieve the coating work on steel cables with different outer diameters, the spacing between the sliders 41 should be an adjustable structure. Therefore, an adjusting ring 22 is movably sleeved on the outer side of the top of the cylinder 2, and the bottom surface of the adjusting ring 22 is provided with a vortex-shaped groove. The top part of the slider 41 protrudes upward and is inserted into the groove, thereby forming a driving structure similar to a chuck. That is, when the adjusting ring 22 rotates, the inner arc surface of the groove will force the protruding part of the top of the slider 41 to slide, and the slider 41 is originally restricted by the groove structure on the opening 21, so it can only move along the inner wall of the groove. If the four sliders 41 are brought together synchronously, their internal diameter can be contracted. If they are expanded outward, their internal diameter will be expanded, thereby realizing the oiling work of steel cables with different outer diameters.

[0037] Moreover, in order to facilitate the staff to make adjustments, an adjustment handle 23 should be added to the top of the adjustment ring 22, and an anti-slip pattern should be provided on the periphery of the adjustment handle 23. In order to avoid affecting the relationship between the adjustment ring 22 and the slider 41 due to the rotation of the cylinder, a shell can be movably installed on the periphery of the adjustment ring, and the shell is fixedly connected to the cylinder, for example Figure 6 As shown, when the cylinder rotates, the adjusting ring and the adjusting handle rotate accordingly.

[0038] When the slider 41 moves, the oil pipe 43 at the bottom thereof is connected to the oil filling ring 45, and thus the oil pipe 43 will gradually bend. Therefore, in this embodiment, the oil pipe 43 and the oil guide pipe 44 used between the two sliders 41 should both be made of rubber bellows for telescopic adjustment.

[0039] In actual use, even if the four sliders 41 cooperate with each other to paint the surface of the steel cable, it is difficult to cover the entire inner wall. Therefore, the entire oiling assembly 4 should be rotated to expand its coating range and further improve its protective effect.

[0040] To realize the above structure, the bottom of the cylinder 2 should be extended to the inside of the base 1, and a toothed portion 24 should be arranged around the outer wall of the bottom end thereof, and then a servo motor 11 is arranged inside the base 1, and a driving gear is provided on the output end of the servo motor 11, and the driving gear is meshed with its toothed portion 24, thereby driving the entire cylinder 2 to rotate, and during the rotation process, the oil filling ring 45 and the slider 41 also rotate synchronously, so the two are in a relatively static state, and the bottom plate 46 at the bottom of the oil filling ring 45 is a rotation connection, so the oiling work will not be affected, so it is only necessary to adjust the inner diameter of the oiling component 4 in this embodiment, and then start it, and cooperate with the lowering or retracting of the winch to apply grease to the surface of the steel cable.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
