For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] like Figure 1 - Figure 5 As shown, the cable dragging and lifting load-bearing assembly provided by the present invention comprises: a cable 6, a load-bearing sleeve, a compression ring, a tension sleeve 3 and a hinge housing 1. The cable 6 can be a steel armored tension-resistant watertight cable 6.

[0040] The cable 6 includes an outer skin and an inner core, wherein the inner core has a wrapped section and a non-wrapped section 12, wherein the outer skin wraps the wrapped section, and the inner core of the non-wrapped section 12 is exposed outside. A reinforcing wire is arranged inside the outer skin to improve the tensile strength of the cable 6, and the reinforcing wire can be made of a metal material, such as a steel wire, or a non-metallic material. A portion of the reinforcing wire extends outward from the inside of the outer skin to one side of the non-wrapped section 12. The wrapped section and the non-wrapped section 12 can be formed by peeling the entire fully wrapped cable 6, wherein a portion of the reinforcing wire is retained during peeling.

[0041] The bearing sleeve is arranged outside the non-wrapped section 12, and the reinforcing wire is attached to the outer wall of the bearing sleeve and is clamped by a compression ring at the end of the bearing sleeve away from the wrapped section. A positioning groove can be arranged on the outer wall of the bearing sleeve, and the positioning groove is arranged from left to right for positioning and accommodating the reinforcing wire. Further, along the length direction of the bearing sleeve, the outer diameter of the bearing sleeve is arranged unevenly, that is, the outer wall of the bearing sleeve presents ups and downs, so that the reinforcing wire attached thereto is subjected to radial force, thereby increasing resistance.

[0042] The anti-tensile sleeve 3 can be conical, which is arranged on the outside of the bearing sleeve and wraps the bearing sleeve, the clamping ring and the reinforcing wire inside; and the interior of the anti-tensile sleeve 3 is filled with a curing glue 41 that immerses the bearing sleeve, the clamping ring and the reinforcing wire. The reinforcing wire is cured by curing the curing glue 41 in the gaps between the reinforcing wires, thereby increasing the tensile strength and meeting the corresponding tensile requirements.

[0043] like Figure 4As shown, the hinge housing 1 is sleeved on the outside of the non-wrapped section 12, and is connected to one end of the anti-tension sleeve 3 facing away from the wrapped section, and the two can be threadedly connected. A groove is provided on the inner side of the right end of the hinge housing 1, and a second injection molded elastomer 5 is provided in the groove, and a non-wrapped section 12 is provided inside the second injection molded elastomer 5. A second sealing ring 10 and a third sealing ring 13 are respectively provided on the inner and outer sides of the right end of the hinge housing 1, wherein the second sealing ring 10 is located between the through hole and the non-wrapped section 12, and the third sealing ring 13 can be provided between the hinge housing 1 and the anti-tension sleeve 3, and a mechanical sealing multi-pass waterproof design is adopted to prevent the anti-tension sleeve 3 from being flooded and causing its bearing effect to fail, thereby ensuring that the overall transmission performance of the cable 6 is not affected.

[0044] The hinge housing 1 is provided with an external thread, and the tension sleeve 3 is provided with an internal thread, so as to realize the threaded connection between the two. In order to further improve the connection stability, a locking screw 14 is provided on the outer wall of the tension sleeve 3, and the locking screw 14 can be made to abut against the outer wall of the hinge housing 1 by rotating the locking screw 14.

[0045] like Figure 3 As shown, in this embodiment, there are two layers of reinforcement wires in the outer skin. Specifically, along the radial direction, the inner skin is provided with an internal reinforcement wire 42 and an external reinforcement wire 47 arranged in sequence from the inside to the outside; the number of the bearing sleeves is two, namely, an internal bearing sleeve 45 and an external bearing sleeve 46, and the internal bearing sleeve 45 is located on the inner side of the external bearing sleeve 46; the internal reinforcement wire 42 is attached to the outer wall of the internal bearing sleeve 45, and the external reinforcement wire 47 is attached to the outer wall of the external bearing sleeve 46; the number of the clamping rings is two, namely, an internal clamping ring 43 and an external clamping ring 44, the internal clamping ring 43 is clamped on the end of the internal bearing sleeve 45 away from the wrapping section, for clamping the internal reinforcement wire 42 on the outer wall of the internal bearing sleeve 45; the external clamping ring 44 is clamped on the end of the external bearing sleeve 46 away from the wrapping section, for clamping the external reinforcement wire 47 on the outer wall of the external bearing sleeve 46. The two layers of reinforcement wires are fixed separately to further improve the tensile strength.

[0046] The outer diameter of the internal bearing sleeve 45 is unevenly arranged, that is, it presents ups and downs. From left to right, the internal bearing sleeve 45 includes a first flat wall, a first inclined wall, a second flat wall and a second inclined wall. Among them, from left to right, the outer diameters of the first flat wall and the second flat wall remain unchanged, the outer diameter of the first inclined wall gradually increases, and the outer diameter of the second inclined wall gradually decreases. The radially convex structure can make the reinforcing wire attached thereto be subjected to radial force, thereby increasing resistance. Correspondingly, the outer diameter of the external bearing sleeve 46 is also unevenly arranged, that is, it presents ups and downs. From left to right, the external bearing sleeve 46 includes a third flat wall, a third inclined wall, a fourth flat wall and a fourth inclined wall. Among them, from left to right, the outer diameters of the third flat wall and the fourth flat wall remain unchanged, the outer diameter of the third inclined wall gradually increases, and the outer diameter of the fourth inclined wall gradually decreases. The radially convex structure can make the reinforcing wire attached thereto be subjected to radial force, thereby increasing resistance.

[0047] Moreover, from left to right, the inner diameter of the external bearing sleeve 46 gradually decreases, so that the external bearing sleeve 46 has an eight-shaped structure, while increasing the contact length between the reinforcing wire and the curing glue 41, thereby improving the friction resistance. When subjected to traction, the inner wall of the external bearing sleeve 46 tightens the curing glue 41 between the external bearing sleeve 46 and the internal bearing sleeve 45, resulting in greater resistance and less likely to detach.

[0048] The inclination angles of the first inclined wall, the second inclined wall, the third inclined wall, the fourth inclined wall and the inner wall of the external load-bearing sleeve 46 are all in the range of 5 to 10 degrees to avoid the outer diameter of the load-bearing component being too large.

[0049] like Figure 5 As shown, the end of the tension sleeve 3 away from the hinge housing 1 is sleeved on the outside of the wrapping section, and a first sealing structure is provided between the tension sleeve 3 and the wrapping section to improve the sealing between the two. Specifically, the first sealing structure includes a first sealing ring 9, a pressure ring 8 and a threaded locking member 7; along the direction of the non-wrapped section 12 toward the wrapping section, the inner hole of the end of the tension sleeve 3 away from the hinge housing 1 includes a thin part, a thick part and a threaded part connected in sequence, the diameter of the thin part is smaller, the diameter of the thick part is larger, and a step surface is formed between the two, the thin part is for the wrapping section to pass, the first sealing ring 9 and the pressure ring 8 are located in the thick part, the first sealing ring 9 abuts on the step surface, the threaded locking member 7 is threadedly connected to the threaded part, and the pressure ring 8 is pressed by rotating the threaded locking member 7, so that the pressure ring 8 squeezes the first sealing ring 9 to achieve sealing. Further, the number of the first sealing ring 9 and the pressure ring 8 can be multiple, and they are alternately arranged to form a multi-stage seal. The surfaces where the first sealing ring 9 and the pressure ring 8 are in close contact with each other are inclined surfaces. The material of the pressure ring 8 is metal, and the material of the first sealing ring 9 can be rubber. Under the extrusion of the metal pressure ring 8, the first sealing ring 9 can undergo greater deformation along the inclined surface, thereby improving the sealing strength.

[0050] A first injection-molded elastomer 11 is injection-molded between one end of the anti-tension sleeve 3 away from the hinge housing 1 and the wrapping section, for sealing the right end of the anti-tension sleeve 3 .

[0051] The front end of the hinge housing 1 is provided with a tuning fork-type lifting lug and a lifting hole, which is convenient for dragging, lifting and fixing.

[0052] The preparation process is as follows:

[0053] Preparation of the load-bearing body of the cable 6: insert the first sealing ring 9, the pressure ring 8, the thread locking piece 7, and the tension sleeve 3 into the cable 6 in sequence.

[0054] Strip off the outer reinforcing wires of the cable 6, straighten them sequentially and bend them backwards according to the original arrangement, then strip off the inner reinforcing wires of the cable 6, straighten them sequentially and bend them backwards according to the original arrangement.

[0055] Then insert the internal load-bearing sleeve 45, straighten the internal reinforcement wires in sequence according to the original arrangement and evenly arrange them on the outer circle of the internal load-bearing sleeve 45, then insert the internal clamping ring 43 onto the outside of the internal reinforcement wires, use special tools to evenly press them as required to ensure that each reinforcement wire is pressed by the internal clamping ring 43, similarly insert the external load-bearing sleeve 46, straighten the external reinforcement wires in sequence according to the original arrangement and evenly arrange them on the outer circle of the external load-bearing sleeve 46, then insert the external clamping ring 44 onto the outside of the external reinforcement wires, use special tools to evenly press them as required to ensure that each reinforcement wire is pressed by the external clamping ring 44.

[0056] Finally, push the tensile sleeve 3 toward the external reinforcing wire to make the two in close contact, and then inject the curing glue 41 into all the gaps according to the proportion, and clean the excess glue after it dries to complete the preparation of the reinforcing wire load-bearing body.

[0057] Parts assembly: Install the second sealing ring 10 into the sealing ring groove of the hinge housing 1, then insert the cable 6, and connect it to the tensile sleeve 3 through threads. Install the first sealing ring 9, the pressure ring 8, and the threaded locking piece 7 from left to right into the inner hole at the right end of the tensile sleeve 3. Finally, the threaded locking piece 7 is connected to the tensile sleeve 3 through threads, and the first sealing ring 9 is pressed to achieve sealing.

[0058] Preparation of injection-molded elastomer: Place the left and right sides of the assembled components into the corresponding molds for integrated injection molding to complete the production of the first injection-molded elastomer 11 and the second injection-molded elastomer 5 of the components. Prevent water from entering the tension sleeve 3 to make it lose its bearing effect, and prevent water from entering the gap in the middle layer of the cable 6 to increase the weight of the cable 6, so as to ensure that the overall transmission performance of the cable 6 is not affected.

[0059] Compared with the prior art, the present embodiment has a small size and high tensile strength, which realizes the requirements of miniaturization, lightness and high tensile strength of underwater equipment, making the retrieval and deployment of underwater equipment more convenient. The present solution can use a steel armored umbilical cable assembly to solve the towing and placement of large underwater equipment and the transmission of signals and power, abandoning the previous use of two cables (one for tensile strength and one for transmission), greatly facilitating the retrieval and use of cables.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention 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 solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
