Composite bus traveling cable for port machinery elevator

Abstract

The invention discloses a composite bus traveling cable for a port machinery elevator. The cable includes an outer sheath and multiple cable units arranged in the outer sheath, wherein the outer sheath includes a sheath body and a separator arranged at the middle of the sheath body, the multiple cable units are arranged in the sheath body side by side, the multiple cable units include two pairs ofshield wires, two communication bus cables and four wire sets, the pairs of shield wires are arranged at the middle of the sheath body and are symmetrically arranged at two sides of the separator, the two communication bus cables are correspondingly arranged at outer sides of the pairs of shield wires in one-to-one correspondence, an outer side of each of the two communication bus cables is respectively disposed with a steel rope twisted in a full reverse-twist mode, and the four wire sets in groups of two are arranged on outer sides of the two steel ropes. The traveling cable has propertiesof reliable electrical performance and stable transmission characteristic, and the whole cable has the balancing structure, bears the uniform force and is wear resistant.

Description

technical field [0001] The invention relates to a composite bus accompanying cable for a port mechanical elevator. Background technique [0002] In port machinery, cables conforming to the Siemens profibus communication bus are installed in fixed slots or chains, while the elevator system for port machinery is a mobile mechanical device that cannot be fixed and used. The communication bus must be combined into the elevator to accompany it. in the cable. At present, coaxial cables, shielded wire pairs, network cables and optical fiber cables are generally used in the accompanying cables of elevators to transmit signals such as media, video, broadcasting, and control commands. However, it is still blank to combine industrial buses into accompanying cables. Basically, one end of the elevator accompanying cable is fixed on the shaft wall, and the other end is fixed on the car, and the middle is free to hang and move; this cannot be installed in the port machinery, because the w...
