Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable guide hole technology, and in particular to a wear-resistant and corrosion-resistant marine cable guide hole structure. Background Technology
[0002] In the daily operations and running of ships, the guide hole plays an indispensable role as a key component for guiding cables. However, traditional marine guide holes face many problems in practical applications that urgently need to be addressed.
[0003] From a wear-resistant perspective, its internal structure is simple, with the cable in direct contact with the inner wall of the guide hole. During frequent cable threading and movement, the friction between the two is significant, leading to severe cable wear and greatly shortening the cable's lifespan. This also affects the stability of ship operations. Moreover, once the wear-resistant components of the guide hole wear out, the entire guide hole often needs to be replaced, resulting in high maintenance costs.
[0004] In terms of corrosion resistance, since ships are in harsh environments such as seawater for a long time, the main material of ordinary cable guide holes is easily corroded by seawater, which leads to structural damage, reduces the performance and service life of the cable guide holes, and increases the frequency and cost of ship maintenance. Utility Model Content
[0005] The purpose of this invention is to provide a wear-resistant and corrosion-resistant marine cable guide hole structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution, which includes a cable guide hole body, an anti-wear component provided on the inner side of the cable guide hole body, and a lubrication component provided on the top of the cable guide hole body.
[0007] As a preferred embodiment of this utility model, the wall of the cable guide hole body is provided with a nano-ceramic coating.
[0008] As a preferred embodiment of this utility model, the wear-resistant component includes a fitting frame disposed on the inner wall of the cable guide hole body, and several replaceable protective rubber sheets disposed on the fitting frame.
[0009] As a preferred embodiment of this utility model, the cable guide hole body is provided with several reinforcing ribs.
[0010] As a preferred embodiment of this utility model, the lubrication assembly includes a pair of oil outlet cylinders. Both oil outlet cylinders are fixed on both sides of the middle reinforcing rib by fixing strips. A one-way inlet valve is provided at the bottom of one side of each oil outlet cylinder, and a one-way outlet valve is provided at the bottom of each oil outlet cylinder. The one-way outlet valve passes through the cable guide hole body, and its outlet is placed in the hole of the cable guide hole body. A pressure rod is movably arranged inside each oil outlet cylinder. A piston head is provided at the bottom of the pressure rod. The pressure rod is located on the outer side of the oil outlet cylinder. A lifting spring is sleeved on the outer side of the pressure rod. The tops of the two pressure rods are connected by a connecting plate, and the lifting spring is abutted between the connecting plate and the oil outlet cylinder. The lubrication assembly also includes a pair of oil storage tanks. The two oil storage tanks are symmetrically arranged on the top of the reinforcing ribs on both sides. The one-way inlet valve is connected to the oil storage tank on the same side by a connecting pipe.
[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0012] 1. This utility model features an anti-wear component installed inside the cable guide hole body, with the fitting frame tightly connected to the inner wall of the cable guide hole body and the protective rubber fixed to the fitting frame. This structure not only fully covers the inner wall of the cable guide hole body, effectively reducing friction between the cable and the cable guide hole, but also allows for the replacement of the protective rubber. When the protective rubber suffers severe wear due to long-term use, it can be easily replaced without replacing the entire cable guide hole structure, thus reducing maintenance costs and extending the service life of the cable guide hole.
[0013] 2. In this utility model, the oil outlet cylinder in the lubrication assembly is securely connected to both sides of the middle reinforcing rib by a fixing strip. The one-way inlet valve and one-way outlet valve are tightly connected to the oil outlet cylinder. The oil storage tank is installed on the top of the two reinforcing ribs and is connected to the one-way inlet valve through a connecting pipe. By manually pressing the connecting plate, the lubricating oil can be added and replenished through the linkage of the pressure rod and the piston head. This design can replenish the lubricating oil on the surface of the anti-wear component at any time according to actual needs, which greatly reduces the friction between the cable and the cable guide hole. This not only reduces cable wear, but also improves the smoothness and safety of cable use during ship operations.
[0014] 3. This utility model uses a nano-ceramic coating on the main wall of the cable guide hole, which is firmly attached through professional spraying and high-temperature sintering processes. The nano-ceramic coating, with its own properties, can effectively resist the erosion of harsh environments such as seawater, greatly enhancing the corrosion resistance of the cable guide hole and ensuring long-term stable operation of the cable guide hole in complex marine environments.

[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 specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0022] like Figures 1-5 As shown, the present invention proposes a wear-resistant and corrosion-resistant marine cable guide hole structure. During the processing of the wall of the cable guide hole body 1, a professional spraying process is used to uniformly spray nano-ceramic material onto the surface of the wall of the cable guide hole body 1. After subsequent treatments such as high-temperature sintering, the nano-ceramic coating 4 is firmly adhered to the wall of the cable guide hole body 1, thereby giving the cable guide hole body 1 good corrosion resistance.
[0023] The anti-wear component 2 is set on the inner wall of the cable guide hole body 1. It includes a fitting frame 20 and a protective rubber sheet 21 is installed on the fitting frame 20 by adhesive. Each protective rubber sheet 21 is tightly spliced together to fully cover the inner wall of the cable guide hole body 1 and play a good anti-wear role.
[0024] The reinforcing rib 10 is connected to the cable guide hole body 1 by welding. After the cable guide hole body 1 is formed, the prefabricated reinforcing rib 10 is firmly connected to the cable guide hole body 1 by welding according to the design position to enhance the structural strength of the cable guide hole body 1.
[0025] The lubrication assembly 3 includes an oil outlet cylinder 30, which is installed on one side of the intermediate reinforcing rib 10 by a fixing strip 31 to ensure that the oil outlet cylinder 30 is stably set on both sides of the intermediate reinforcing rib 10. A one-way inlet valve 32 and a one-way outlet valve 33 are respectively set on one side and bottom of the oil outlet cylinder 30. A pressure rod 35 is movably installed inside the oil outlet cylinder 30. A piston head 36 is set at the bottom of the pressure rod 35. A lifting spring 37 is sleeved on the section of the pressure rod 35 located outside the oil outlet cylinder 30. One end of the lifting spring 37 abuts against the connecting plate 38, and the other end abuts against the top of the oil outlet cylinder 30. The elastic force of the spring realizes the reset function of the pressure rod 35. The connecting plate 38 is connected to the top of the two pressure rods 35 by welding to ensure a firm connection and to drive the two pressure rods 35 to move synchronously.
[0026] At the corresponding positions on the top of the two reinforcing ribs 10, an oil reservoir 39 is installed. One end of the connecting pipe 34 is connected to the one-way inlet valve 32, and the other end is connected to the oil reservoir 39 to ensure a tight connection, thereby realizing the function of lubricating oil communication between the oil reservoir 39 and the oil outlet cylinder 30.
[0027] When in use, first thread the cable through the cable guide hole body 1. When the cable moves in the cable guide hole, in order to reduce the friction between the cable and the cable guide hole structure, it is necessary to lubricate the key parts.
[0028] When lubricating oil needs to be added, the operator manually presses the connecting plate 38 continuously. During this process, the connecting plate 38 presses down the pressure rod 35, which then moves downward in a straight line within the oil outlet cylinder 30. Since the oil outlet cylinder 30 is equipped with a piston head 36, the downward pressing action of the pressure rod 35 pushes the piston head 36 downward within the oil outlet cylinder 30. Under the squeezing action of the piston head 36, the pressure of the lubricating oil in the oil outlet cylinder 30 increases, thus overcoming the resistance of the one-way discharge valve 33 and dripping from the one-way discharge valve 33 onto the surface of the wear-resistant component 2. This achieves lubrication of the wear-resistant component 2 and the cable contact parts, effectively reducing friction. When the operator releases their hand... When the oil outlet cylinder 30 is in use, the two lifting springs 37 on both sides of the oil outlet cylinder 30 will come into play. One end of the lifting spring 37 is connected to the oil outlet cylinder 30, and the other end is connected to the connecting plate 38. The lifting spring 37 generates an upward elastic force due to the release of its own elastic potential energy, which pushes the connecting plate 38 to move upward. The connecting plate 38 drives the pressure rod 35 to reset. During the reset process, the piston head 36 moves upward synchronously, and a negative pressure environment is formed in the oil outlet cylinder 30. At this time, the lubricating oil in the oil tank 39 is drawn into the oil outlet cylinder 30 through the connecting pipe 34 under the action of atmospheric pressure, thus completing the replenishment of lubricating oil. By repeatedly pressing the connecting plate 38, lubricating oil can be continuously added to the anti-wear component 2.
[0029] In addition, the protective rubber pads of the cable guide hole structure are in direct contact with the cable, and wear is inevitable during long-term use. When the protective rubber pads are severely worn, it is not necessary to replace the entire cable guide hole structure. Simply remove the worn protective rubber pads and replace them with new ones. This design greatly reduces maintenance costs and improves the efficiency and lifespan of the cable guide hole structure.
[0030] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
