Multi-functional vertical type twisting and untwisting cable forming machine

Abstract

A multi- functional vertical type twisting and untwisting cable forming machine comprises a main speed reduction variable frequency motor and a twisting rotation disc, wherein three large rotation discs and three fixed small rotation discs are uniformly arranged on the twisting rotation disc, the large rotation discs and the fixed small rotation discs are arranged in a crossed way, and nine movable small rotation discs are fixedly arranged at the outer side of the circumference of the twisting rotation disc and uniformly distributed; the processing of a submarine cable is achieved by the three large rotation discs and the three fixed small rotation discs, and the processing of a multi-core umbilical cable is achieved by the three fixed small rotation discs and the nine movable small rotation discs; and an annular large gear ring is arranged at the lower end of the twisting rotation disc, support wheel devices are arranged on the large gear ring, uniformly distributed and connected with a guide rail in a matching way, and the outer side of the large gear ring is engaged with a small gear arranged on the main speed reduction variable frequency motor. By the cable forming machine, the full untwisting before the long-length multi-core submarine cable is formed and twisted and the twisting and forming of the multi-functional umbilical cable can be achieved.

Description

technical field [0001] The invention relates to a cable forming machine, in particular to a multifunctional vertical twisting and untwisting cable forming machine. Background technique [0002] At present, Chinese submarine cable manufacturers mostly use vertical cable forming machines to produce three-core optical fiber composite submarine cables. The stranding of a multi-core composite submarine cable including 3 power cables and 3 optical cables, among which the three small-diameter optical cables are paid out in a reel, the optical cables are taken up in the reel, and the reel is placed on a fixed pay-off rack , the pay-off rack is installed on the small back-twist tray; the other three large-diameter power cable cores adopt tray-type pay-off, and the wires are directly collected and arranged in the back-twist tray for passive pay-off. The large back-twist tray with this structural design The diameter, stacking height and size of the small reel-type pay-off rack will be...

Problems solved by technology

[0003] This kind of vertical twisting and untwisting cable forming machine, in the process of twisting the cores into a cable, each core has two kinds of motions: straight line and rotation, and the rotation of the multi-core cores is realized through the rotation of the twisting large turntable; through The power drive configured on the production line of the subsequent process realizes the axial linear movement of the wire core such as wire release and take-up. When the wire core rotates one revolution, the distance that the insulated wire core advances in the axial direction is the "cable pitch". The above-mentioned "cable pitch" is a key control parameter to measure the quality of semi-products in the cabling process and whether the back-twist is complete. If the production line is not equipped with a large-tonnage traction machine and a drive system for back-twist drive, it will be difficult to realize the cable core The untwisting function during stranding cannot meet the standard requirements for the cable pitch in the production process
