Description

Technical Field

[0001] This utility model belongs to the field of cable laying technology, and more specifically, relates to a component suitable for cable laying on inclined roads. Background Technology

[0002] In modern industry and construction, cable laying is a crucial step in the construction of power transmission and communication systems, especially at sloping wharves, where water level fluctuations significantly impact the operation of wharf facilities and equipment. The water level in the wharf area is affected by various factors, such as tides, seasonal rainfall, and changes in river flow, resulting in regular or irregular rises and falls in the water level of the wharf area.

[0003] During the operation of a ramp wharf, the cable laying is not static after completion but requires dynamic adjustments based on water level changes. When the water level drops, the pontoon connected to the wharf will descend accordingly. At this time, the cable winch on the pontoon must release the cable accordingly to ensure that the cable always maintains an appropriate degree of slack, avoiding damage to the internal structure of the cable due to excessive stretching or causing power outages. Conversely, when the water level rises, the pontoon rises, and the cable winch needs to promptly retract the cable to prevent it from piling up, tangling, or colliding with wharf facilities due to excessive slack, thereby ensuring the normal power supply function and service life of the cable.

[0004] However, in actual cable winding and unwinding processes, the friction between the cable and the support or sliding groove is significant during sliding, easily leading to wear on the cable sheath, reducing service life, and increasing safety hazards. Secondly, during cable winding and unwinding, if there is an eccentricity between the original cable laying channel and the cable winch (i.e., the winch position is not perfectly aligned with the straight cable laying channel), the cable will be subjected to a diagonal pulling force during winding and unwinding, being pulled to the side. This diagonal pulling action will cause the cable to rub against the side wall of the laying channel or other surrounding facilities, thus scratching the cable sheath. Damage to the cable sheath not only affects its appearance but also significantly reduces the cable's insulation performance and protective capabilities. This damage makes the cable more susceptible to corrosion from external environmental factors such as water and humid air during subsequent use, and also increases the risk of mechanical damage. This not only shortens the cable's service life but may also lead to serious safety hazards, such as cable-to-ground short circuits, causing short circuit safety accidents and power outages. Utility Model Content

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a cable laying component suitable for inclined ramps. It combines rotating tubes of different diameters to form a complete sliding assembly, which is then spliced ​​together in a horizontal and vertical arrangement to create a cable laying sliding channel. This allows the cable to slide smoothly during laying, reducing friction between the cable sheath and the rotating tubes, effectively protecting the cable sheath from wear. Simultaneously, when the cable slides to the side due to eccentricity, the rotating tubes on the side can continue to roll and limit the cable's sliding range, ensuring the cable always slides within a predetermined area and preventing damage due to excessive deviation.

[0006] To achieve the above objectives, this utility model provides a component suitable for cable laying on inclined ramps, including a base, with a first connecting pipe and a second connecting pipe welded to both ends of the base, and a bottom connecting pipe welded between the first connecting pipe and the second connecting pipe near the bottom.

[0007] A first rotating tube is sleeved on the outside of the first connecting tube, and the first rotating tube can rotate around the first connecting tube as an axis. A second rotating tube is sleeved on the outside of the second connecting tube, and the second rotating tube can rotate around the second connecting tube as an axis. A bottom rotating tube is sleeved on the outside of the bottom connecting tube, and the bottom rotating tube can rotate around the bottom connecting tube as an axis.

[0008] The bottom rotating tube, the first rotating tube, and the second rotating tube cooperate to form a sliding channel for cable laying. The sliding channel is groove-shaped and is used to accommodate the cable. By combining rotating tubes of different diameters, a complete sliding assembly is formed. The cable laying sliding channel is spliced ​​together in a horizontal and vertical arrangement, allowing the cable to slide smoothly during the laying process, reducing the friction between the cable sheath and the rotating tube, and effectively protecting the cable sheath from wear. At the same time, when the cable slides to the side due to eccentricity, the rotating tube on the side can continue to roll and limit the sliding range of the cable, ensuring that the cable always slides within the predetermined area and avoiding damage due to excessive deviation.

[0009] Furthermore, a limit rod is rotatably connected to the top of the second connecting tube.

[0010] Furthermore, the base is made of angle steel with dimensions of L50×50×5mm.

[0011] Furthermore, the bottom connecting pipe, the first connecting pipe, and the second connecting pipe are all made of stainless steel pipe with a diameter of φ20mm.

[0012] Furthermore, the bottom rotating tube, the first rotating tube, and the second rotating tube are all made of stainless steel tubes with a diameter of φ32mm.

[0013] Furthermore, both the first and second rotating tubes are welded with cover plates at their tops, and after the cover plates are welded to the steel pipes, their periphery is finely ground, resulting in a smooth and round surface without any burrs or protrusions.

[0014] Furthermore, the height of the second rotating tube is not higher than the height of the guard wheel sill.

[0015] Furthermore, one end of the base is welded and fixed to a pre-embedded steel plate embedded in the side of the ramp; or the base is directly fixed to the side of the ramp by expansion bolts.

[0016] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0017] (1) The present invention provides a cable laying component suitable for inclined ramps. By combining rotating tubes of different diameters, a complete sliding component is formed. The components are spliced ​​together in a horizontal and vertical arrangement to form a cable laying sliding channel, so that the cable can slide smoothly during the laying process, reducing the friction between the cable sheath and the rotating tube, effectively protecting the cable sheath from wear. At the same time, when the cable slides to the side due to eccentricity, the rotating tube on the side can continue to roll and limit the sliding range of the cable, ensuring that the cable always slides within the predetermined area and avoiding damage due to excessive deviation.

[0018] (2) This utility model provides a cable laying component suitable for inclined ramps. By using stainless steel pipes to make the bottom connecting pipe, bottom rotating pipe, first connecting pipe, first rotating pipe, second connecting pipe, and second rotating pipe, the adaptability and durability of the cable laying component in humid or harsh environments are improved. Stainless steel not only has excellent corrosion resistance, effectively resisting the erosion of external factors such as moisture, salt spray, and chemicals, but also has high strength and toughness, ensuring that the component maintains structural stability during long-term use and is not easily deformed or damaged.

[0019] (3) The present invention provides a cable laying component suitable for inclined ramps. By providing a limiting rod at the top of the cable laying channel, the cable is prevented from jumping out of the cable laying channel during the laying process, thereby ensuring the safety and stability of cable laying. In areas where cable winding and unwinding operations are required, the limiting rod 8 can be rotated open to facilitate the smooth entry and exit of the cable. In areas where cable winding and unwinding are not required, the limiting rod can be rotated closed to effectively limit the range of cable movement and ensure that the cable always runs within the predetermined path. This not only improves the safety of cable laying but also enhances the flexibility of operation. Attached Figure Description

Detailed Implementation

[0026] 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. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figs. 1-3As shown, this utility model provides a cable laying component suitable for inclined ramps, including a base 1. A first connecting pipe 4 and a second connecting pipe 6 are welded to both ends of the base. A bottom connecting pipe 2 is welded between the first connecting pipe 4 and the second connecting pipe 6 near the bottom. A first rotating pipe 5 is sleeved on the outside of the first connecting pipe 4, and the first rotating pipe 5 can rotate about the first connecting pipe 4 as an axis. A second rotating pipe 7 is sleeved on the outside of the second connecting pipe 6, and the second rotating pipe 7 can rotate about the second connecting pipe 6 as an axis. A bottom rotating pipe 3 is sleeved on the outside of the bottom connecting pipe 2, and the bottom rotating pipe 3 can rotate about the bottom connecting pipe 2 as an axis. The bottom rotating pipe 3, the first rotating pipe 5, and the second rotating pipe 7 cooperate with each other to form a sliding channel for cable laying. The sliding channel is groove-shaped and is used to accommodate the cable 10. This utility model uses rotating tubes of different diameters combined in a component. These steel tubes cooperate with each other through a carefully designed structure to form a complete sliding assembly. By arranging them horizontally and vertically, these sliding assemblies can be spliced ​​into a cable laying sliding channel. During cable laying, the cable can slide smoothly on this sliding channel. Since the outer bottom rotating tube 3 can rotate around the bottom connecting tube 2 as the cable slides, the friction between the cable sheath and the bottom rotating tube 3 can be significantly reduced, thereby effectively protecting the cable sheath from wear. In addition, when the cable slides and causes eccentricity, causing the cable to slide to the side, the first rotating tube 5 and the second rotating tube 7 on the side can rotate around the first connecting tube 4 and the second connecting tube 6 as the cable slides, which can significantly reduce the friction between the cable sheath and the first rotating tube 5 and the second rotating tube 7, thereby effectively protecting the cable sheath from wear. On the other hand, it can also limit the sliding range of the cable, ensuring that the cable always slides within a predetermined area, avoiding damage or other accidents caused by excessive cable deviation, improving the efficiency of cable laying, and enhancing the safety and reliability of the cable laying process.

[0028] Furthermore, a limiting rod 8 is rotatably connected to the top of the second connecting pipe 6. The main function of the limiting rod 8 is to prevent the cable from jumping out of the cable laying channel during the laying process, thereby ensuring the safety and stability of the cable laying. In areas where cable winding and unwinding operations are required, the limiting rod 8 can be rotated open to facilitate the smooth entry and exit of the cable; while in areas where cable winding and unwinding are not required, the limiting rod can be rotated closed to effectively limit the range of cable movement, ensuring that the cable always runs within the predetermined path. This not only improves the safety of cable laying but also enhances operational flexibility, adapts to various laying environments, reduces maintenance costs, and has a simple structure that is easy to operate and maintain.

[0029] Furthermore, the tops of the first rotating tube 5 and the second rotating tube 7 are both welded with cover plates. After the cover plates are welded to the steel pipes, their periphery is finely ground, and the surface is round and smooth without any burrs or protrusions. When the channel is immersed in water, it prevents sand, silt and other impurities from flowing into the gap between the inner and outer steel pipes, thereby blocking the sliding channel and preventing the outer steel pipe of the cable from sliding normally, affecting the smoothness of cable laying, and ensuring the normal operation of the cable laying sliding channel in the underwater environment and the smooth laying of the cable.

[0030] Furthermore, the base 1 is made of L50×50×5mm angle steel. It provides a stable supporting foundation for the entire cable laying structure. Its L-shaped cross-section not only has good load-bearing capacity but also effectively distributes stress, ensuring stability in complex laying environments.

[0031] Furthermore, the bottom connecting pipe 2, the first connecting pipe 4, and the second connecting pipe 6 are all made of stainless steel pipe with a diameter of φ20mm.

[0032] Furthermore, the bottom rotating tube 3, the first rotating tube 5, and the second rotating tube 7 are all made of stainless steel tubes with a diameter of φ32mm.

[0033] Specifically, the stainless steel material gives these steel pipes excellent corrosion resistance and wear resistance, enabling them to operate stably for a long time in humid or harsh environments, further extending the service life of the entire cable laying structure.

[0034] Furthermore, the height of the second rotating tube 7 is not higher than the height of the guard wheel sill, making the entire cable laying component more visually coordinated and unified, avoiding the abruptness caused by protruding parts, improving the overall appearance, and making the cable laying system more tidy and standardized in the on-site environment after installation.

[0035] Furthermore, one end of the base 1 is welded and fixed to the pre-embedded steel plate 9 embedded in the side of the ramp; or the base 1 is directly fixed to the side of the ramp by expansion bolts. In this embodiment, it is preferred that one end of the base 1 is welded and fixed to the pre-embedded steel plate 9 embedded in the side of the ramp.

[0036] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
