Description

Technical Field

[0001] This invention belongs to the field of cable technology, and in particular relates to a cable for a storage frame suspension device. Background Technology

[0002] Cranes, port machinery, and high-altitude mobile equipment require multiple up-and-down movements every day. Suspension cables play a crucial role in signal transmission and power supply during use. However, due to their reciprocating motion, existing suspension cables frequently experience cable twisting and deformation, signal unit breakage, and cable bulging. Furthermore, cable twisting and deformation can cause the cable to sway in the air, resulting in the storage frame deviating upon landing. This poses a safety hazard to the use of high-altitude mobile equipment. Therefore, existing technologies have shortcomings and deficiencies. Summary of the Invention

[0003] The purpose of this invention is to provide a storage frame suspension cable that solves problems such as twisting and deformation, swaying in the air, deviation from the frame, easy breakage of signal units, cable bulging, and poor bending resistance of existing suspension cables.

[0004] The technical solution adopted by the present invention to solve the above problems is as follows:

[0005] A storage frame suspension cable includes a load-bearing unit, a reinforcing core, an insulated core unit, a wrapping layer, a counterweight lead core, a fiber braided reinforcing layer, and an outer sheath layer;

[0006] The carrying unit is located at the center of the cable, and several reinforcing cores are disposed between the carrying unit and the fiber braided reinforcing layer. The carrying unit and the reinforcing cores are used to enhance the flexibility and dynamic balance of the cable.

[0007] The insulated core units are distributed in a ring around the outside of the reinforcing core, and the wrapping layer is disposed on the outside of the cable core. The insulated core units and the reinforcing core are twisted together to form the cable core, which makes the signal units of the cable less prone to breakage and less prone to twisting and deformation.

[0008] The counterweight lead core is filled between every two adjacent wrapping layers and the fiber braided reinforcement layer. The counterweight lead core is used to prevent the cable from swinging in the air and deviating from the frame when it falls.

[0009] The outer sheath layer is disposed outside the fiber braided reinforcement layer. The outer sheath layer is a flexible elastic material layer with a strength of not less than 18MPa and an elongation of more than 300%. The fiber braided reinforcement layer and the outer sheath layer are used to prevent the cable from bulging and bending.

[0010] Furthermore, the supporting unit is a Kevlar fiber core unit.

[0011] Furthermore, the reinforcing core is composed of flexible steel wire formed by regular twisting of multiple fine and soft steel wires and a steel wire protective layer covering the flexible steel wire. The steel wire protective layer of the reinforcing core is an environmentally friendly polyvinyl chloride elastomer sheath layer.

[0012] Alternatively, the reinforcing core may be a fiber-reinforced composite material.

[0013] Furthermore, each of the insulated core units is tangent to the reinforcing core and the wrapping layer, and every two adjacent insulated core units are tangent to each other. Each of the wrapping layers is tangent to the bearing unit and the fiber braided reinforcing layer, and every two adjacent wrapping layers are tangent to each other, in order to achieve lightweight and simplified cable installation.

[0014] Furthermore, the insulated core unit includes a conductive conductor and an insulating layer, the insulating layer being extruded onto the outside of the conductive conductor, and the insulated core unit being disposed on the outside of the reinforcing core.

[0015] Furthermore, the conductive conductor is a Class V or Class VI conductor, and the insulating layer is a composite elastomer material.

[0016] Furthermore, the counterweight lead cores are arranged symmetrically in equal quantities, with an even number of cores greater than or equal to 2. Each counterweight lead core has the same weight, and each counterweight lead core is tangent to two adjacent wrapping layers and fiber braided reinforcing layers.

[0017] Furthermore, the fiber braided reinforcing layer is an aramid fiber reinforcing layer.

[0018] Furthermore, the flexible elastic material of the outer sheath layer is a polyurethane elastomer.

[0019] Furthermore, the fiber braided reinforcing layer and the outer sheath layer are concentrically arranged.

[0020] The beneficial effects of the present invention by adopting the above technical solution are as follows:

[0021] This invention provides the cable with good flexibility and dynamic balance by setting up a reinforcing core and a load-bearing unit; by twisting the reinforcing core together with an insulated core unit, the signal unit is less prone to breakage and the cable is less prone to twisting and deformation; by setting up an equal and symmetrical counterweight lead core, the problems of cable swaying in the air and deviation from the frame are solved; and by setting up a fiber braided layer and an outer sheath layer, the problems of cable bulging and poor bending resistance are solved.

[0024] To make the objectives, technical solutions, and beneficial effects of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, the present invention provides a storage frame suspension cable, including a bearing unit 1, a reinforcing core 2, an insulated core unit 3, a wrapping layer 4, a counterweight lead core 5, a fiber braided reinforcing layer 6, and an outer sheath layer 7.

[0026] The fiber braided reinforcing layer 6 is provided with a bearing unit 1 concentric with the fiber braided reinforcing layer 6. The bearing unit 1 is located at the center of the cable. Several reinforcing cores 2 are provided between the bearing unit 1 and the fiber braided reinforcing layer 6. The bearing unit 1 and the reinforcing cores 2 are used to enhance the flexibility and dynamic balance of the cable.

[0027] Several conductive conductors 31 are provided on the outside of the reinforcing core 2. Each conductive conductor 31 is covered with an insulating layer 32 to form an insulated wire core unit 3. The insulated wire core units 3 are distributed in a ring outside the reinforcing core 2. The insulated wire core units 3 and the reinforcing core 2 are twisted together to form a cable core, making the signal unit less likely to break and the cable less likely to be twisted or deformed.

[0028] Each cable core is surrounded by a wrapping layer 4, which is distributed in a ring around the outside of the bearing unit 1. Between each two adjacent wrapping layers 4 and the fiber braided reinforcement layer 6, there is a counterweight lead core 5. The number of counterweight lead cores 5 is an even number greater than or equal to 2. Each counterweight lead core 5 has the same weight. By setting an equal and symmetrical number of counterweight lead cores, the problems of cable swaying in the air and deviation from the frame are solved.

[0029] The outer sheath layer 7 is disposed outside the fiber braided reinforcement layer 6. The outer sheath layer 6 is a flexible elastic material layer with a strength of not less than 18MPa and an elongation of more than 300%. The fiber braided reinforcement layer 6 and the outer sheath layer 7 are used to prevent the cable from bulging and bending.

[0030] In this embodiment, the load-bearing unit 1 is a Kevlar fiber core unit, and the reinforcing core 2 is a flexible steel wire formed by regular twisting of multiple fine and soft steel wires and a steel wire protective layer covering the flexible steel wire. The steel wire protective layer of the reinforcing core 2 is an environmentally friendly polyvinyl chloride elastomer sheath layer. The reinforcing core 2 can also be a fiber-reinforced composite material, such as carbon fiber, glass fiber, and aramid fiber. By setting the reinforcing core 2 and the load-bearing unit 1, the cable has good flexibility and dynamic balance.

[0031] In this embodiment, each of the insulated core units 3 is tangent to the reinforcing core 2 and the wrapping layer 4 respectively, and each pair of adjacent insulated core units 3 is tangent to each other. Each of the wrapping layers 4 is tangent to the bearing unit 1 and the fiber braided reinforcing layer 6 respectively, and each pair of adjacent wrapping layers 4 is tangent to each other. Each of the counterweight lead cores 5 is tangent to each of the two adjacent wrapping layers 4 and the fiber braided reinforcing layer 6 respectively, thereby achieving lightweight and simplified cable installation.

[0032] In this embodiment, the conductive conductor 31 is a Category 5 or Category 6 conductor. Category 5 or Category 6 conductors have a finer diameter and are more flexible, with smaller gaps between the individual filaments. When the conductors are stranded, the bundled filaments and the twisted filaments are in the same direction. The insulating core unit 3 can be kept tangent by adjusting the filling area between every two adjacent insulating core units 3, depending on the number of cores. The insulating layer 32 is a composite elastomer material. Specifically, the composite elastomer material can be a nitrile butadiene composite elastomer, and the extrusion is performed by compression molding.

[0033] In this embodiment, the fiber braided reinforcing layer 6 is an aramid fiber reinforcing layer, which has good wear resistance and shear resistance, and high strength. The outer sheath layer 7 is a flexible elastic material layer with a strength of not less than 18MPa and an elongation of more than 300%. Specifically, the flexible elastic material can be a polyurethane elastomer, and the extrusion is performed by compression. This elastic material layer is suitable for reciprocating motion applications and has high mechanical strength, high and low temperature resistance, environmental aging resistance, and other composite properties, solving the problems of cable bulging and poor bending resistance.
