Description

TECHNICAL FIELD

[0001] The utility model relates to superconducting cable cabling equipment technical field, concretely relates to a novel superconducting cable cabling tension control device. BACKGROUND

[0002] The superconducting cable conductor is made by grading and twisting a plurality of superconducting single wires. Due to the late use requirement, the conductor roundness and straightness have extremely strict standard requirements, and cannot appear oval or snake phenomenon. Therefore, the twisting tension must be strictly controlled in the twisting of the superconducting cable at all levels to prevent uneven tension between the conductors during twisting, so that the superconducting cable cannot meet the design requirements, cannot be put into the pipe and armored, and cannot be wound into the magnet coil.

[0003] The traditional cabling machine pay-off tension control device is composed of a friction disc, a tension belt, a spring and an adjusting mechanism. The friction disc is installed on the pay-off shaft and rotates with the pay-off disc, the tension belt is fixed on the rack, and the size of the pay-off tension is controlled by adjusting the tension of the tension belt to adjust the friction force on the friction disc during production. Since the tension of the superconducting cable 5-level cable is large during cabling, the tension belt needs to generate a large friction force on the friction disc, which causes the tension belt and the friction disc to wear out quickly, burrs are generated on the surface of the friction disc, and the tension cannot be guaranteed to be stable. Due to the unstable tension, the tension between the pay-off discs is greatly different, which cannot guarantee uniform and stable output, thereby causing the twisted superconducting cable to have non-standard roundness and snake phenomenon.

[0007] The cradle frame 1 is composed of two vertically symmetrical support plates, the pay-off shaft 5 is arranged on the inner side of each support plate through a bearing, the pay-off disc 2 is arranged between the two support plates, the two pay-off shafts 5 are fixed on the two sides of the pay-off disc 2, the large gear 3 is fixed on the rear pay-off shaft 5, and the gear reducer 6 is installed on the top of the rear support plate.
