[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0054] In the description of the present invention, it should be understood that the terms "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0055] The object of the present invention is to provide an elastic cable hose, an elastic cable hose assembly and a preparation method, which can improve the tensile strength and telescopic performance of the elastic cable.

[0056] See also Figure 1 and Figure 2 To achieve the above-mentioned purpose, the present invention provides an elastic cable hose, including a hose body.

[0057] The hose body comprises a rubber inner core layer 1, a fiber braided layer 2, and a rubber protective layer 3 which are arranged in sequence from the inside to the outside. The thickness of the rubber protective layer 3 is 2.0 mm-2.5 mm.

[0058] The fiber braided layer 2 includes a first braided layer formed by braiding a plurality of first braided wires along a first braiding angle, a second braided layer formed by braiding a plurality of second braided wires along a second braiding angle, and the second braided layer is located at the periphery of the first braided layer.

[0059] The first braiding angle and the second braiding angle are 58°-68°.

[0060] It should be noted that the first braiding angle of the first braided wire located on the inner side and the second braiding angle of the second braided wire located on the outer side are usually different, and the second braiding angle is usually slightly larger than the first braiding angle. For example, when the first braiding angle is 61°, the second braiding angle can be 62°. The braiding angle refers to the angle at which the direction of the braided wire is inclined relative to the axis of the rubber inner core layer 1.

[0061] By arranging a fiber braided layer 2 outside the rubber inner core layer 1, the fiber braided layer 2 is two layers, including a first braided layer on the inner side and a second braided layer on the outer side, and by setting the first braiding angle of the first braided wire to 58°-68°, a first braided layer with greater elasticity and better tensile performance is formed by weaving, and by setting the second braiding angle of the second braided wire to 58°-68°, a second braided layer with greater elasticity and better tensile performance is formed by weaving. Such an arrangement can improve the tensile and telescopic properties of the elastic cable.

[0062] Among them, the first braided wire and the second braided wire are specifically ultra-high molecular weight polyethylene fibers, the fiber strokes of the first braided layer and the second braided layer are equal, that is, the axial distances of the first braided layer and the second braided layer on the rubber inner core layer 1 are consistent, and a silicone oil layer is provided on the surface of the first braided layer and the second braided layer.

[0063] See also Figure 3 and Figure 4 An elastic cable hose assembly includes the above-mentioned elastic cable hose, the end faces of the rubber inner core layer 1 and the rubber protective layer 3 are flush, the end face of the rubber inner core layer 1 is provided with a mounting hole, and the fiber braided layer 2 includes a plurality of braided wires extending outside the end face.

[0064] It can be understood that a metal joint including the metal inner core 4 and the sleeve 6 described below needs to be installed on the elastic cable hose. In the present embodiment, the elastic cable hose is placed in a preset position for fixing, and then the elastic 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 peeled rubber protective layer 3, so that the end faces of the rubber inner core layer 1 and the rubber protective layer 3 are flush, and the unpeeled fiber braided layer 2 includes a number of braided wires extending outside the end face. According to the size of the metal inner core 4 described below, a hole is drilled at the center of the end face of the rubber inner core layer 1 to form a mounting hole.

[0065] It should be noted that, in the above-mentioned stripping process, an independent splint can be added, and the elastic cable hose can be fixed by the clamping piece in the splint. The splint is provided with a first scale mark with the position of the clamping piece as the starting point. The rubber protective layer 3 is stripped to the preset scale value, and then the rubber inner core layer 1 is stripped to the corresponding scale value position.

[0066] In addition, clamping marks and peeling marks can also be set on the rubber protective layer 3 to facilitate the clamping of the rubber protective layer 3 at the same position, and to facilitate the uniform peeling of the rubber protective layer 3 to the peeling mark position, so as to improve the accuracy and efficiency of the peeling of the elastic cable hose.

[0067] The elastic cable hose assembly further comprises a metal inner core 4 and a first colloid.

[0068] The metal inner core 4 includes a connecting portion 41 and an abutting portion 42 connected to each other, wherein the connecting portion 41 is installed in the mounting hole, and the abutting portion 42 abuts against the end face of the metal inner core 4, wherein the mounting hole is specifically a threaded hole, and the connecting portion 41 is a stud with threaded threads circumferentially arranged, and a sealing adhesive is arranged on the surface of the connecting portion 41 for rapid polymerization of the connecting portion 41 and the rubber inner core layer 1, thereby improving the stability of the connection between the connecting portion 41 and the rubber inner core layer 1, and after installation, there is no gap between the metal inner core 4 and the rubber inner core layer 1.

[0069] The first colloid is used to soak the braided wire and twist it to the side of the abutment portion 42 away from the connection portion 41 to form a fiber block 5. The braided wire is specifically ultra-high molecular weight polyethylene fiber. The first colloid can be epoxy resin structural adhesive to achieve the above purpose.

[0070] See also Figures 5 to 8 In this embodiment, the elastic cable hose assembly also includes a sleeve 6, a fixing part 7 and a connecting part 8. The sleeve 6 is sleeved on one end of the hose body on which the metal inner core 4 is installed, and the sleeve 6 includes a crimping section 61 that can be sleeved on the outer periphery of the hose body and crimped by a crimping mold; the fixing part 7 is provided with a plurality of connecting holes 71; the connecting part 8 is detachably inserted into the connecting hole 71 and can be screwed into the sleeve 6 to squeeze the fiber block 5.

[0071] Among them, the sleeve 6 includes an internal thread section and a guide section, the guide section includes the above-mentioned crimping section 61, and a plate body is provided inside the guide section, the plate body can move in 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 body to move to extrude the fiber block 5. Specifically, the partial guide section of the sleeve 6 with the plate body is sleeved on the 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 inside of the guide section to tighten the plate body and drive the plate body to extrude the fiber block 5 including the epoxy resin structural glue, and then the crimping section 61 is formed by crimping in the crimping area A of the sleeve 6 through a special crimping mold for the elastic cable hose assembly, the fixing member 7 and the connector 8 are removed to wait for the fiber block 5 to solidify and form, and then multiple groups of elastic cable hose assemblies can be detachably assembled through the fixing member 7 and the connector 8 according to actual needs.

[0072] The cross-sectional diameter of the abutment portion 42 perpendicular to its own axis is larger than the cross-sectional diameter of the crimping 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, and be able to withstand higher tensile forces without causing separation between the elastic cable hose and the metal joint.

[0073] By improving the tensile and telescopic properties of the elastic cable hose, the telescopic properties of the elastic cable hose assembly enable it to adapt to different water levels and tidal changes. Whether it is tidal fluctuations or water level changes, the elastic cable hose can automatically adjust its length, maintain good tension, and maintain a stable connection between the pontoon and the dock. Whether it is a small dock or a large dock, the elastic cable hose assembly can be customized according to actual conditions to meet different engineering needs. The elastic cable hose assembly is made of ultra-high molecular weight polyethylene material, wear-resistant rubber and customized metal joints. It has good durability and corrosion resistance. It can withstand long-term exposure to corrosion in seawater environments and daily wear and tear, greatly extending its service life. The elastic cable hose assembly can absorb the impact of waves, tides and wind on the dock pontoon, reduce vibration and swing through its elastic properties, and increase the stability of the pontoon.

[0074] The fixing member 7 may be a metal disc having a plurality of connection holes 71 evenly arranged around the circumference of the metal disc, and the connecting member 8 may be bolts, etc., so that maintenance personnel can quickly perform maintenance and replacement, reduce downtime, and improve work efficiency.

[0075] In addition, it also includes a preparation method for preparing the above-mentioned elastic cable hose, including: after the inner rubber is pressed out of the inner core, it is cooled and formed, and after a long period of cooling, it is tension-free rolled up to obtain a rubber inner core layer 1; an ultra-high molecular weight polyethylene fiber braided layer 2 and a rubber protective layer 3 are laid on the rubber inner core layer 1 to obtain a composite layer; and the composite layer is vulcanized to obtain an elastic cable hose.

[0076] Among them, the steps of pressing the inner rubber out of the inner core, cooling and shaping it, and then winding it without tension after a long cooling to obtain the rubber inner core layer 1 include: pressing the inner core out and vulcanizing it to obtain the rubber inner core layer 1, during vulcanization, first increasing the pressure for 9-10 minutes to 0.15MPa and vulcanizing it at a constant pressure for 15-25 minutes (preferably 20 minutes), then increasing the pressure to 0.25Mpa and vulcanizing it at a constant pressure for 25-35 minutes (preferably 30 minutes), and finally increasing the pressure to 0.35Mpa and vulcanizing it at a constant pressure for 35-45 minutes (preferably 40 minutes).

[0077] In addition, an ultra-high molecular weight polyethylene fiber braided layer 2 and a rubber protective layer 3 are laid on the rubber inner core layer 1 to obtain a composite layer, the steps comprising: placing the ultra-high molecular weight polyethylene wire fibers used for braiding the 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, and after drying, evenly applying a layer of silicone oil on the surface of the fiber braided layer 2 and then laying the rubber protective layer 3.

[0078] The specific steps of vulcanizing the composite layer to obtain the elastic cable hose are as follows: placing the composite layer in an environment with an air pressure of 0.3-0.35MPa, heating it to 143°C, keeping it warm for 40 minutes and then cooling it down to complete the vulcanization treatment to obtain the elastic cable hose.

[0079] The relevant time, air pressure and temperature during vulcanization can be adjusted within a range of plus or minus 20%, which can also achieve the above purpose.

[0080] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
