Problems solved by technology
[0002] At present, the Siemens profibus communication bus cables used in the crane spreaders in the steel and machinery industries are all fixed and used, and it is extremely inconvenient to install and arrange the cables; while the lead-containing bead spreader cables commonly used in port machinery have no effective electromagnetic protection and are easy to Signal interference occurs, which brings inconvenience to signal transmission, so it cannot be used as a signal control spreader cable. At present, there is no cable storage basket spreader cable that integrates bus cables and signal control cables.

Embodiment 1
[0023] This embodiment relates to a cable storage basket spreader cable of a composite bus, such as figure 1 As shown, the Siemens 6XV1830-3EH10 bus cable with special soft structure and polyurethane sheath is selected as the bus cable 1 of the composite cable; in order to solve the problem of signal interference, the signal control cable adopts fine composite reinforced conductor 2, insulation layer 3, and each pair of wires The core adopts a pair-twisted structure, and the first inner sheath 4 filled with plastic is provided at the gap, and the composite shielding layer 5 is sequentially covered, and the fiber wrapping layer 6; then the bus cable 1 and the signal control cable surround the central tensile strength member 7, The cable is assembled with an optimized pitch-to-diameter ratio. The entire cable is equipped with a second inner sheath 8 filled with plastic, a tensile and torsion-resistant braid 9, and a high-wear-resistant polyurethane sheath material as the outer sh...

Abstract
The invention discloses a cable storage basket spreader cable for a composite bus; the spreader cable includes an outer sheath, a tensile and torsion-resistant braided layer, a second inner sheath, and a second inner sheath. The total cable core assembled by bus cables and signal control cables around the central tensile strength member inside the sleeve. The control wire core pair of the present invention adopts composite shielding to have excellent electromagnetic shielding effect, avoids interference to bus cables, and ensures data transmission; fiber-reinforced conductor, aramid rope tensile center and Kevlar braided torsion-resistant layer and The double-layer polyurethane sheath ensures that the cable can withstand the self-weight of the cable in the vertical lifting and acceleration state, and the pitch ratio of the twisted pair and the overall cable is controlled at about 10 times, and the cabled direction is the same, which ensures the flexibility of the cable , the cable can be freely coiled in the cable storage basket; these all ensure the convenience of cable installation and use and the excellent control and communication signal transmission of the cable.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to a cable storage basket spreader cable for a composite bus. Background technique [0002] At present, the Siemens profibus communication bus cables used in the crane spreaders in the steel and machinery industries are all fixed and used, and it is extremely inconvenient to install and arrange the cables; while the lead-containing bead spreader cables commonly used in port machinery have no effective electromagnetic protection and are easy to The signal interference problem occurs, which brings inconvenience to signal transmission, so it cannot be used as a signal control spreader cable. At present, there is no cable storage basket spreader cable that integrates bus cables and signal control cables. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a new cable storage basket spreader...
