Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a ship cable with tensile strength. Background Technology

[0002] As a critical safety component for ship navigation and berthing, mooring lines play an indispensable role in operations such as berthing, towing at sea, and cargo hoisting. However, in actual use scenarios, ships in complex sea conditions, especially when encountering large waves or rapid currents, experience violent swaying and displacement of the hull, causing mooring lines to frequently experience significant changes in tension and alternating forces. Under this dynamic load, the connection between the mooring line and the ship's mooring bollard, as well as the rope's own knot, are prone to the following problems: First, repeated friction at the connection causes wear and peeling of the outer protective layer of the mooring line, and the internal fibers gradually loosen, reducing the overall strength of the mooring line; second, the knot, under the continuous action of alternating stress, forms a stress concentration point, causing premature fatigue failure of the mooring line material, leading to sudden breakage of the mooring line, and consequently causing serious safety accidents such as loss of ship control.

[0003] To effectively solve the above-mentioned technical problems, we have proposed a ship cable with tensile strength. Utility Model Content

The docking assembly includes an upper buffer cylinder and a lower threaded cylinder. A sliding rod is slidably inserted into the inner side of the upper buffer cylinder, and a built-in movable disc is fixedly installed on the inner end of the sliding rod. A spring is fixedly connected between the upper side of the built-in movable disc and the top of the inner side of the upper buffer cylinder. The sliding rod slides through to the outside of the upper buffer cylinder, and an upper lug is fixedly installed on the upper end of the sliding rod. A fixing rod is fixedly installed on the lower end of the lower threaded cylinder, and a convex disc is fixedly installed on the lower end of the fixing rod.

[0014] Compared with related technologies, the ship cable with tensile strength proposed in this utility model has the following beneficial effects:

[0015] In this invention, a ship cable with tensile strength is provided. The cable assembly includes an upper buffer cylinder and a lower screw cylinder. A spring inside the upper buffer cylinder provides cushioning to the sliding rod, thus ensuring a buffered connection at the cable joint after connection.

Furthermore, the cable is made of high-strength nylon, offering high tensile strength and good wear resistance. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Reference Figures 1-4 A ship cable with tensile strength includes an upper ship cable 1 and a lower ship cable 2, with a docking assembly 3 between the upper ship cable 1 and the lower ship cable 2. The docking assembly 3 includes an upper buffer cylinder 31 and a lower screw cylinder 32. A sliding rod 35 is slidably inserted into the inner side of the upper buffer cylinder 31. An internal movable disc 36 is fixedly installed on the inner end of the sliding rod 35. A spring 37 is fixedly connected between the upper side of the internal movable disc 36 and the top of the inner side of the upper buffer cylinder 31. The sliding rod 35 slides through to the outside of the upper buffer cylinder 31, and an upper hanging lug 39 is fixedly installed on the upper end of the sliding rod 35. A fixing rod 310 is fixedly installed on the lower end of the lower screw cylinder 32. A convex disc 311 is fixedly installed on the lower end of the fixing rod 310. A rotating ring 312 is rotatably sleeved on the outside of the fixing rod 310. A lower hanging lug 313 is fixedly installed on the lower side of the rotating ring 312.

[0023] In this method, a limiting hole 34 is provided on the side wall of the upper buffer cylinder 31, and a limiting screw 314 is screwed onto the side wall of the lower screw cylinder 32, with the inner end of the limiting screw 314 inserted into the inner side of the limiting hole 34.

[0024] With the above configuration, the upper buffer cylinder 31 and the lower screw-connector cylinder 32 are connected by screws. In daily use, to prevent the cable from transmitting some torque between the upper buffer cylinder 31 and the lower screw-connector cylinder 32 when it rotates, the limiting screw 314 is tightened so that the inner end of the limiting screw 314 is inserted into the inner side of the limiting hole 34. This restricts the degree of freedom of rotation between the screwed upper buffer cylinder 31 and the lower screw-connector cylinder 32, preventing them from becoming loose.

[0025] In this method, several limiting posts 38 are fixedly installed at equal intervals on the top circumference of the inner side of the upper buffer cylinder 31.

[0026] With the above-mentioned configuration, when subjected to tension, the built-in movable plate 36 at the inner end of the slide rod 35 will press against the spring 37, causing the spring 37 to be compressed. When the spring 37 reaches its limit of compression, the built-in movable plate 36 will abut against the limit post 38, preventing excessive deformation of the spring 37 and protecting the spring 37.

[0027] In this method, both the upper ship cable 1 and the lower ship cable 2 are made of high-strength nylon fiber.

[0028] Through the above-mentioned design, high-strength nylon material possesses characteristics of high tensile strength and good wear resistance.

[0029] In this method, the upper ship cable 1 is tied to the upper lug 39, and the lower ship cable 2 is tied to the lower lug 313. Both the upper ship cable 1 and the lower ship cable 2 are fitted with metal locking rings 4 on their outer sides. The metal locking rings 4 are made of high-strength aluminum alloy.

[0030] Through the above-described design, aluminum alloy tubes possess advantages such as high strength, light weight, and strong corrosion resistance.

[0031] In this design, the spring 37, the upper buffer cylinder 31, and the lower screw cylinder 32 are all made of high-strength stainless steel.

[0032] By adopting the above-mentioned configuration, the main components of the entire docking assembly 3 have good structural strength and corrosion resistance.

[0033] In this configuration, the lower outer side of the upper buffer cylinder 31 is provided with an external thread 33, and the lower threaded cylinder 32 is threadedly sleeved on the outside of the upper buffer cylinder 31.

[0034] The working principle of the ship cable with tensile strength provided by this utility model is as follows:

[0035] In use, when a ship encounters strong winds, waves, or rapids, the hull rolls and shifts violently, and the mooring lines experience significant changes in tension and direction. At this time, the tension on the upper mooring line 1 is transmitted to the upper lug 39, causing the slide bar 35 to slide within the upper buffer cylinder 31 under the action of the spring 37. The spring 37 is compressed, absorbing and buffering the tension, preventing stress concentration at the mooring line connection, and protecting the mooring line from sudden damage by tensile force. When the spring 37 reaches its limit under compression, the built-in movable disc 36 abuts against the limit post 38 to prevent excessive deformation of the spring 37, further ensuring the reliability of the buffer structure. At the same time, the tension of the lower ship cable 2 is transmitted through the lower hanging ear 313. Since the swivel ring 312 can rotate freely outside the fixed rod 310, the lower hanging ear 313 can rotate adaptively, allowing the cable to rotate with the force direction when it changes, avoiding the cable from twisting and knotting during daily use, and reducing the damage to the cable caused by knotting. Throughout the entire working process, the upper ship cable 1 and the lower ship cable 2, made of high-strength nylon fiber, continuously and stably bear the tension due to their high tensile strength and good wear resistance. The main components of the docking assembly 3, such as the spring 37, the upper buffer cylinder 31, and the lower screw cylinder 32, made of high-strength stainless steel, ensure the long-term stable operation of the buffer and connection functions with their excellent structural strength and corrosion resistance, thereby significantly improving the tensile strength of the ship cable and reducing the probability of safety accidents such as loss of control of the ship due to cable problems.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
