Abstract

A multi-functional vertical twisting and untwisting cable machine, including a main deceleration variable frequency motor and a twisting body turntable, and three large turntables and three fixed small turntables are uniformly arranged on the twisting body turntable, and the large turntable Cross-distributed with the fixed small turntable, nine evenly distributed small movable turntables are fixedly installed on the outside of the circumference of the winch turntable, and the three large turntables and three fixed small turntables realize the processing of submarine cables. The three fixed small turntables and the nine movable small turntables realize the processing of multi-core umbilical cables. The lower end of the twisted turntable is provided with an annular large ring gear, and the large ring gear is equipped with evenly distributed The supporting wheel device, the supporting wheel device is connected with the guide rail, and the outer side of the large ring gear meshes with the pinion gear installed on the main reduction frequency conversion motor. This cable forming machine can realize the cable forming of large-length multi-core submarine cables Full untwisting before twisting and twisting of multifunctional umbilical cables.

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

[0004] This "three big and three small" six-reel pay-off configuration will be limited in the production of deep-sea umbilical cables. Products, according to the laying water depth and user requirements, commonly used umbilical cables have multi-core structures such as 9 cores, 10 cores, 11 cores, 13 cores, 24 cores, and 63 cores. The reel configuration is far from meeting the production requirements of umbilical cables

[0005] At the same time, this tray-type passive pay-off structure, before the cable forming process in the factory, the power cable core needs to be vertically collected and arranged in the back-twisting tray through the high-altitude guide wheel device, and the final core is manually adjusted by the worker. Stacking, each layer of cores added to the stacking height will produce 360° self-torsion due to torsion. During the process, the wire core will reverse 360° every time it is picked up. In summary, the repeated torsion process makes the wire core extremely vulnerable to mechanical damage. Internal stress is generated on the wire core, resulting in knotting and looping of the cable core, and the entire cabling process fails
