Embodiment Construction

[0015] Such as figure 1 The illustrated embodiment is as follows: a large-scale crane with a twist-resistant signal cable consists of a conductor 1, an insulating layer 2, a core 3, a cable core 4, a filled core post 5, an inner sheath 6, an outer sheath 7, and a main core 8. The ground wire core 9 and the communication wire core 10 are composed. The insulating layer 2 is extruded on the conductor 1 to form the core 3, and a circle of the core 3 is closely arranged on the periphery of the filled core column 5 to form the cable core 4, and the inner sheath 6 is extruded on the periphery of the cable core 4, and the outer sheath 6 Extrude the outer sheath7.

[0016] The conductors 1 are all multi-twisted composite structures of thin copper wires with high-conductivity plating.

[0017] The wire core 3 is composed of a main wire core 8 , a ground wire core 9 and a communication wire core 10 .

[0018] The filled core column 5 is made of aramid fiber material.

[0019] The inn...

Abstract

The invention discloses a flexible signal cable for a huge crane. The flexible signal cable consists of a conductor, an insulating layer, a wire core, a cable core, a stuffing stem, an internal jacket, an external jacket, a main wire core, a grounding wire core and a communication wire core; the insulating layer is extruded on the conductor to form the wire core; a circle of the wire core is tightly arranged at the periphery of the stuffing stem to form the cable core; the internal jacket is extruded at the periphery of the cable core; and the external jacket is extruded at the periphery of the internal jacket. The invention provides the flexible signal cable for the huge crane, which has the advantages of good electrical conductivity, strong signal transmission capability, strong flexibility, capability of high-speed repeated movement and long service; and in particular, the flexible signal cable for the huge crane is suitable for the equipment such as the large crane which is used for rapidly moving articles upward and downwards or leftwards and rightwards when elements are lifted, needs powerful power support and needs to transmit a large amount of information with the outside.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to the technical field of cables for large cranes, in particular to a twist-resistant signal cable for large cranes. Background technique [0002] At present, large-scale hoisting machinery needs not only strong power support but also a large amount of information transmission with the outside world during operation. Large cranes need high-power electric support to quickly move items up and down or left and right when hoisting components, and also need to transmit a large amount of information to make the objects be hoisted in place accurately and quickly. Traditional power cables can only provide power but not information transmission at the same time, let alone fast and high-frequency movement with equipment. Traditional cables also have disadvantages such as difficult installation, high cost, easy deformation of the cable, and short service life. With the rapid develop...
