A fully automatic tension cage stranding machine

Abstract

The invention discloses a full-automatic tension cage stranded wire cable crane, which is subjected to PLC (programmable logic controller) programming control. The full-automatic tension cage stranded wire cable crane comprises a rack, wherein the rack is provided with a main crane seat and a main transmission support; the main crane seat is provided with a main crane motor; the main transmission support is fixedly arranged on one end of a center shaft; the other end of the center shaft is fixedly arranged on an auxiliary supporting seat; a rotating body is fixedly supported by the auxiliary supporting seat; meanwhile, an end of the auxiliary supporting seat is provided with a non-contact short wire detection switch; three transition gears are evenly distributed around the center shaft; each transition gear is meshed with two transmission gears; each transmission gear drives one magnetic tape tension paying-off cradle; and each magnetic tape tension paying-off cradle is fixedly arranged on two mounted bearings. The full-automatic tension cage stranded wire cable crane disclosed by the invention has the advantages of simple structure, low cost, high detection accuracy, no damage on cables, stable torque and even cable tightness, and thin cables can be detected.

Description

technical field [0001] The invention relates to a cable twisting machine, in particular to a fully automatic tension cage cable twisting machine. Background technique [0002] The automatic tension cage cable stranding machine is widely used. The current automatic tension cage cable stranding machine adopts the friction damping with rope as the tension. However, due to the different strength of the wire reel, the torque is unstable during stranding. The tension of the cable varies, and the current cable pay-off is actively rotated into a bundle, and the disconnection detection relies on the metal to conduct electricity to give an information alarm, and then this detection method has three shortcomings. 1. Disconnection detection There is a possibility of false alarms, 2. It is invalid for non-conductor or ultra-thin wires, because the thin wire may be disconnected during the offline movement of rotation. 3. Some cables with high requirements on appearance and appearance may ...

[0002] The automatic tension cage stranding machine is widely used. The current automatic tension cage stranding machine adopts the frictional damping with rope as the tension. However, due to the different tension of the reel, the torque is unstable when twisting. The tension of the cables is different, and the current cable pay-off is actively rotated, and the disconnection detection relies on metal conduction to give an information alarm, and this detection method has three shortcomings, 1. Disconnection detection There is a possibility of false alarms. 2. It is invalid for non-conductor or ultra-thin wires, because the offline movement of the rotation may cause the thin wires to break. 3. For some cables with high appearance requirements, it will cause accidental scratches. There are more than Insufficient, so need to continue to improve
