Description

Technical Field

[0001] This utility model relates to the field of cables, and more specifically, to an oil-resistant and wear-resistant cable storage frame lifting device cable. Background Technology

[0002] Cable loader frames are specialized connecting cables primarily used for the storage, control, and connection of cable baskets in medium to large-sized equipment. They are particularly suitable for vertical cage applications with high mechanical stress. Cable loader frames are widely used in the lifting and hoisting industry, in harsh working environments such as construction sites, mining machinery, container cargo handling, waste treatment plants, railway platforms, and shipyard cranes.

[0003] Existing cable reel cables, especially in harsh environments (such as humidity, oil contamination, and low temperatures), are prone to wear, aging, and even cracking of their outer sheaths during long-term use, leading to decreased cable performance and shortened service life. Due to insufficient weight and stability, existing cable reel cables are easily displaced by wind and other factors, affecting normal use and safety. Some cable reel cables are also prone to breakage and fracture when subjected to mechanical damage such as friction and compression, resulting in decreased cable performance. During installation or use, some cable reel cables may be damaged due to excessive tensile force, rendering them unusable or requiring frequent replacement. Utility Model Content

[0004] The present invention aims to overcome the defects of the prior art and provide an oil-resistant and wear-resistant cable storage frame lifting device cable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil-resistant and wear-resistant cable sling, comprising an outer sheath, a waterproof layer, and an outer wrapping layer arranged sequentially from the outside to the inside. The outer wrapping layer contains a tensile unit, multiple cable cores, and multiple first lead bead chains. The multiple cable cores are arranged in a ring with equal spacing and surround the tensile unit. The tensile unit includes a tensile rope and a covering layer enclosing the tensile rope. The cable core includes an inner sheath and an inner wrapping layer located inside the inner sheath. The inner wrapping layer contains a second lead bead chain and multiple wire cores arranged in a ring with equal spacing and surrounding the second lead bead chain. The wire cores, from the outside to the inside, include an insulation layer, a fire-resistant layer, and a conductor. The outer sheath is made of polyurethane. The outer side of the first lead bead chain is covered with a first braided tensile layer, and the outer side of the second lead bead chain is covered with a second braided tensile layer.

[0006] Furthermore, the tensile rope is made of aramid yarn, and the covering layer is made of PVC or rubber material.

[0007] Therefore, aramid yarn rope is used to improve the tensile strength of the cable.

[0008] Furthermore, the waterproof layer is made of aluminum-plastic composite tape.

[0009] This improves the waterproof performance of the cable.

[0010] Furthermore, both the outer and inner wrapping layers are made of thermoplastic polyurethane.

[0011] This protects the internal core of the cable from damage, improving the overall performance and durability of the cable.

[0012] Furthermore, the inner sheath is made of PVC material.

[0013] Furthermore, both the first and second woven tensile layers are made of aramid fiber.

[0014] This further enhances the tensile strength of the cable.

[0015] Furthermore, there are six of each of the cable cores and the first lead bead chain, with one of the first lead bead chains between two adjacent cable cores and the outer cladding.

[0016] This not only makes the cable cross-section more uniform, but also enhances the overall structural stability of the cable.

[0017] Furthermore, each cable core contains 6 of the aforementioned wire cores.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The cable of the cable storage frame lifting device of this application has a polyurethane sheath as its outer sheath, which gives the cable the characteristics of wear resistance, oil resistance and cold resistance.

Detailed Implementation

[0028] 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.

[0029] This utility model provides, for example Figure 1-4 The illustrated oil-resistant and wear-resistant cable sling frame includes, from the outside to the inside, an outer sheath 1, a waterproof layer 2, and an outer wrapping layer 3. The outer wrapping layer 3 contains a tensile unit, multiple cable cores 5, and multiple first lead bead chains 6. The multiple cable cores 5 are arranged in a ring with equal spacing and surround the tensile unit. The tensile unit includes a tensile rope 4.1 and a wrapping layer 4.2 covering the tensile rope 4.1. The cable core 5 includes an inner sheath 5.1 and a layer located within the inner sheath 5.1. The inner sheath 5.2 has a second lead bead chain 7 and multiple wire cores inside. The multiple wire cores are distributed in a ring with equal spacing and surround the second lead bead chain 7. The wire cores include an insulation layer 5.3, a fire-resistant layer 5.4 and a conductor 5.5 from the outside to the inside. The outer sheath 1 is made of polyurethane. The outer side of the first lead bead chain 6 is covered with a first braided tensile layer 6.1, and the outer side of the second lead bead chain 7 is covered with a second braided tensile layer 7.1.

[0030] The tensile rope 4.1 is made of aramid yarn, and the sheathing layer 4.2 is made of PVC or rubber. The waterproof layer 2 is made of aluminum-plastic composite tape. The outer wrapping layer 3 and the inner wrapping layer 5.2 are both made of thermoplastic polyurethane. The inner sheath 5.1 is made of PVC. The first braided tensile layer 6.1 and the second braided tensile layer 7.1 are both made of aramid fiber braiding. There are six cable cores 5 and six first lead bead chains 6, with one first lead bead chain 6 between two adjacent cable cores 5 and the outer wrapping layer 3. Each cable core 5 contains six of the aforementioned wire cores.

[0031] Working Principle: The cable of this application, a cable sling frame, is manufactured by arranging multiple cores in a ring at equal intervals, surrounding a second lead bead chain that is covered with a second braided tensile layer. Next, thermoplastic polyurethane is wrapped around the core assembly to form an inner sheath, thus assembling the multiple cores into a single unit. Then, a layer of PVC material is extruded over the inner sheath to form an inner sheath, protecting the cable's internal structure and forming the cable core. Next, multiple cable cores are arranged in a ring at equal intervals, surrounding an aramid yarn rope, and the aramid yarn rope is wrapped with PVC or rubber to fill the central gaps, thereby reducing cable costs while meeting tensile strength requirements. Finally, thermoplastic polyurethane is wrapped around the core assembly to form an outer sheath, and a first lead bead chain covered with a first braided tensile layer is placed between the outer sheath and between two adjacent cable cores. Next, an aluminum-plastic composite tape is longitudinally wrapped around the outer sheath to form a waterproof layer, thereby preventing moisture from entering the cable and protecting the cable from the effects of a humid environment. Then, polyurethane material is extruded over the waterproof layer to form an outer sheath, which further improves the cable's abrasion resistance and oil resistance, and protects the cable from damage from the external environment.

[0032] The cable in this application's cable sling and hoist features first and second lead bead chains that increase the cable's weight, ensuring stability in complex environments, preventing displacement, and improving the cable's mechanical properties while protecting its internal structure. The aramid yarn rope and the first and second lead bead chains enhance the cable's tensile strength. This allows the cable to withstand greater weight during vertical installation and use, reducing the risk of breakage. The cable's waterproof layer uses an aluminum-plastic composite tape, effectively preventing moisture from entering the cable and maintaining normal operation even in humid environments. Furthermore, the cable's outer sheath is made of polyurethane, offering excellent wear resistance, oil resistance, and cold resistance. This makes the cable less susceptible to damage from frequent bending and coiling, and ensures stable performance in oily environments.

[0033] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
