Problems solved by technology

[0002] Port machinery is frequently hoisted, and the supporting cables often move at high speed, which is prone to deformation and broken cores.
[0003] At the same time, due to the complexity of the port machinery and the variety of goods to be transported, attention must be paid to fire prevention. The cables must have high flame-retardant properties. The flame-retardant properties of ordinary rubber-sheathed cables are average, and the safety performance is great

Embodiment Construction

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below in conjunction with the accompanying drawings.

[0026] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of the present invention, including a core 1 , a cable core, an inner sheath 2 , a braid 3 and an outer sheath 4 .

[0027] The cable core is formed by twisting a plurality of wire cores 1 , and the number of cable cores is three during specific implementation. The inner sheath 2 is extruded on the outer periphery of the cable core. In practice, the inner sheath 2 is formed by extruding neoprene on the outer periphery of the cable core. Since no filler and wrapping tape are added between the inner sheath 2 and the cable core , Directly extrude the neoprene rubber on the cable core, and the rubber can be embedded in the gap of the core 1, so that when the cable is subje...

Abstract

The invention discloses a cable for harbour machinery. The cable comprises wire cores, a cable core, an inner sheath, a braided layer and an outer sheath. The cable core is formed by twisting a plurality of the wire cores, the inner sheath extrudes on the periphery of the cable core, the braided layer is arranged outside the inner sheath, and the outer sheath coats the braided layer; each wire core comprises a tensile element, a conductor layer and an insulating layer; a strand wire, formed by twisting a plurality of conductor wires, is reversely and repeatedly twisted on the periphery of the tensile element to form one conductor layer; and each insulating layer coats the corresponding conductor layer. The cable for the harbour machinery has the advantages of high tensile performance, high tear resistance, oil resistance, weather resistance, high cold resistance, salt spray resistance, high flame retardance and the like.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable for port machinery. Background technique [0002] Port machinery is frequently hoisted, and the supporting cables often move at high speed, which is prone to deformation and broken cores. [0003] At the same time, due to the complexity of the port machinery and the variety of goods being transported, attention must be paid to fire prevention. The cables must have high flame-retardant properties. The flame-retardant properties of ordinary rubber-sheathed cables are average, and the safety performance is greatly reduced. [0004] In addition, there are many mechanical equipment in the port area, the temperature difference between day and night is large, and it must also withstand the erosion of the sea breeze, which contains a lot of salt, so the cable must have the characteristics of oil resistance, cold resistance, temperature resistance, and salt spray resistance. Ordina...
