[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] In the description of this utility model, it should be understood that the terms "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0045] The purpose of this invention is to provide an elastic cable hose and an elastic cable hose assembly, which can improve the tensile and elongation performance of elastic cables.

[0046] Please see Figure 1 and Figure 2 To achieve the above objectives, this utility model provides an elastic cable hose, including a hose body.

[0047] The hose body includes, from the inside out, a rubber inner core layer 1, a fiber braided layer 2, and a rubber protective layer 3, with the thickness of the rubber protective layer 3 being 2.0mm-2.5mm.

[0048] The fiber braided layer 2 includes a first braided layer formed by weaving a plurality of first braided threads along a first braiding angle, and a second braided layer formed by weaving a plurality of second braided threads along a second braiding angle, wherein the second braided layer is located on the outer periphery of the first braided layer.

[0049] The first and second knitting angles are 58°-68°.

[0050] It should be noted that the first weaving angle of the first weaving line located on the inner side and the second weaving angle of the second weaving line located on the outer side are usually different, and the second weaving angle is usually slightly larger than the first weaving angle. For example, when the first weaving angle is 61°, the second weaving angle can be 62°. The weaving angle refers to the angle at which the direction of the weaving line is tilted relative to the axis of the rubber inner core layer 1.

[0051] By setting a fiber braided layer 2 outside the rubber inner core layer 1, the fiber braided layer 2 consists of two layers, including an inner first braided layer and an outer second braided layer. By setting the first braiding angle of the first braiding line to 58°-68°, a first braided layer with greater elasticity and better tensile performance is formed. By setting the second braiding angle of the second braiding line to 58°-68°, a second braided layer with greater elasticity and better tensile performance is formed. This configuration can improve the tensile and elongation performance of the elastic cable.

[0052] Specifically, the first braided wire and the second braided wire are ultra-high molecular weight polyethylene fibers. The fiber strokes of the first braided layer and the second braided layer are equal, that is, the distance between the first braided layer and the second braided layer in the axial direction of the rubber inner core layer 1 is the same. The surfaces of the first braided layer and the second braided layer are provided with silicone oil layers.

[0053] Please see Figure 3 and Figure 4 An elastic cable hose assembly includes the aforementioned elastic cable hose, with the end faces of the rubber inner core layer 1 and the rubber protective layer 3 flush, the end face of the rubber inner core layer 1 having an installation hole, and the fiber braided layer 2 including a plurality of braided threads extending beyond the end face.

[0054] It is understood that a metal connector including the metal inner core 4 and sleeve 6 needs to be installed on the flexible cable hose. In this embodiment, the flexible cable hose is placed in a preset position and fixed. Then, the flexible cable hose is peeled off. First, the rubber protective layer 3 is peeled off to the required position. The ultra-high molecular weight polyethylene fiber braided layer 2 is arranged and the inner core rubber layer is peeled off, so that the size of the inner core rubber layer is consistent with the size of the rubber protective layer 3 that has been peeled off, so that the end faces of the rubber inner core layer 1 and the rubber protective layer 3 are flush. The unpeeled fiber braided layer 2 includes several braided lines extending beyond the end face. According to the size of the metal inner core 4, a hole is drilled at the center of the end face of the rubber inner core layer 1 to form an installation hole.

[0055] It should be noted that, in the above peeling process, an independent clamping plate can be added. The elastic cable hose is fixed by the clamping parts in the clamping plate. The clamping plate is marked with the first scale mark starting from the position of the clamping parts. After peeling the rubber protective layer 3 to the preset scale value, the rubber inner core layer 1 can be peeled to the corresponding scale value position.

[0056] In addition, clamping marks and peeling marks can be set on the rubber protective layer 3 so that the clamping parts can clamp the rubber protective layer 3 at the same position, and at the same time, the rubber protective layer 3 can be peeled to the peeling mark position in a unified manner, so as to improve the accuracy and efficiency of peeling the elastic cable hose.

[0057] The flexible cable hose assembly also includes a metal inner core 4 and a first gel.

[0058] The metal inner core 4 includes a connecting part 41 and an abutting part 42 connected to each other. The connecting part 41 is installed in the mounting hole, and the abutting part 42 abuts against the end face of the metal inner core 4. The mounting hole is specifically a threaded hole, and the connecting part 41 is a stud with threads in the circumferential direction. The surface of the connecting part 41 is provided with a sealing adhesive for rapid polymerization of the connecting part 41 and the rubber inner core layer 1, thereby improving the stability of the connection between the connecting part 41 and the rubber inner core layer 1. After installation, there is no gap between the metal inner core 4 and the rubber inner core layer 1.

[0059] The first colloid is used to wet and twist the braided thread to the side of the abutment 42 away from the connecting part 41 to form a fiber block 5. The braided thread is specifically ultra-high molecular weight polyethylene fiber. The first colloid can be epoxy resin structural adhesive, as long as it can achieve the above purpose.

[0060] Please see Figures 5 to 8 In this embodiment, the elastic cable hose assembly further includes a sleeve 6, a fixing member 7, and a connector 8. The sleeve 6 is sleeved on the end of the hose body where the metal inner core 4 is installed, and the sleeve 6 includes a clamping section 61 that can be sleeved on the outer periphery of the hose body and clamped by a clamping mold. The fixing member 7 is provided with a plurality of connecting holes 71. The connector 8 is detachably inserted through the connecting holes 71 and can be screwed into the sleeve 6 to compress the fiber block 5.

[0061] The sleeve 6 includes an internal thread section and a guide section. The guide section includes the aforementioned crimping section 61 and has a plate inside. The plate can move within the guide section along the extension direction of the sleeve 6. The connector 8 cooperates with the internal thread section of the sleeve 6 so that the end of the connector 8 pushes the plate to move, thereby squeezing the fiber block 5. Specifically, a portion of the guide section of the sleeve 6 with the plate is fitted onto a preset position of the elastic cable hose. The fixing member 7 and the connector 8 are installed, and the connector 8 is screwed into the guide section to tighten the plate and cause the plate to squeeze the fiber block 5, which includes epoxy resin structural adhesive. Then, the crimping section 61 is formed in the crimping area A of the sleeve 6 using a special crimping mold for elastic cable hose assembly. The fixing member 7 and the connector 8 are removed to allow the fiber block 5 to solidify. Then, multiple sets of elastic cable hose assemblies can be detachably assembled using the fixing member 7 and the connector 8 as needed.

[0062] The cross-sectional diameter of the abutment portion 42 perpendicular to its own axis is larger than the cross-sectional diameter of the crimped section 61 perpendicular to the axis of the abutment portion 42 after crimping, so as to achieve mutual locking of the sleeve 6 and the metal inner core 4 in opposite directions, which can withstand higher tensile force without causing the elastic cable hose to separate from the metal joint.

[0063] By improving the tensile and elongation properties of the flexible cable hose, the assembly's flexibility allows it to adapt to different water levels and tidal changes. Whether due to tidal fluctuations or water level changes, the flexible cable hose automatically adjusts its length to maintain good tension and ensure a stable connection between the floating bridge and the dock. Whether for small or large docks, the flexible cable hose assembly can be customized to meet diverse engineering needs. Made of ultra-high molecular weight polyethylene, wear-resistant rubber, and custom metal joints, the flexible cable hose assembly boasts excellent durability and corrosion resistance, withstanding long-term exposure to seawater and daily wear, significantly extending its service life. The flexible cable hose assembly absorbs the impact of waves, tides, and wind on the floating bridge, reducing vibration and swaying through its elastic properties and increasing the bridge's stability.

[0064] The fastener 7 can be a metal disc with several connecting holes 71 evenly arranged around its circumference. The connector 8 can be bolts or the like, which allows maintenance personnel to quickly perform repairs and replacements, reduce downtime, and improve work efficiency.

[0065] In addition, a preparation method is included for preparing the above-mentioned elastic cable hose, comprising: pressing the inner rubber out of the inner core and cooling and shaping it, and then winding it up without tension after long cooling to obtain a rubber inner core layer 1; laying an ultra-high molecular weight polyethylene fiber braided layer 2 and a rubber protective layer 3 on the rubber inner core layer 1 to obtain a composite layer; and vulcanizing the composite layer to obtain an elastic cable hose.

[0066] The steps of pressing the inner rubber into the inner core, cooling and shaping it, and then rolling it up without tension after a long cooling period to obtain the rubber inner core layer 1 include: pressing the inner core and then vulcanizing it to obtain the rubber inner core layer 1. During vulcanization, the pressure is first increased to 0.15 MPa for 9-10 minutes and then stabilized for 15-25 minutes (preferably 20 minutes), then increased to 0.25 MPa and stabilized for 25-35 minutes (preferably 30 minutes), and finally increased to 0.35 MPa and stabilized for 35-45 minutes (preferably 40 minutes).

[0067] In addition, the steps of laying ultra-high molecular weight polyethylene fiber braided layer 2 and rubber protective layer 3 on rubber inner core layer 1 to obtain composite layer include: placing ultra-high molecular weight polyethylene fibers used to braid ultra-high molecular weight polyethylene fiber braided layer 2 in a drying room for more than 12 hours before use, drying the braided fiber braided layer 2 for more than 12 hours after braiding, and then uniformly applying a layer of silicone oil to the surface of the fiber braided layer 2 before laying rubber protective layer 3.

[0068] The specific steps for vulcanizing the composite layer to obtain the elastic cable hose are as follows: the composite layer is placed in an environment with an air pressure of 0.3-0.35MPa, heated to 143℃, kept at that temperature for 40 minutes, and then cooled to complete the vulcanization process and obtain the elastic cable hose.

[0069] The relevant time, air pressure, and temperature during vulcanization can all be adjusted within a range of plus or minus 20%, and the above objectives can still be achieved.

[0070] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0071] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
