Description

Auxiliary conveying device for cable cabling and cable cabling equipment

Technical Field

The utility model relates to a cable technical field, specifically speaking relates to supplementary conveyer of cable stranding and cable stranding equipment.

Background

The superconducting cable is most favored for large capacity power transmission mainly with its zero loss transmission characteristic, and the large capacity characteristic is high voltage and high current. The two measures, namely, the realization of high voltage requires higher insulation and voltage resistance grade and the realization of high current requires more layers of superconducting tapes, and both measures can cause different structures of the superconducting cable, thereby causing the outer diameter of the superconducting cable to be increased.

The conventional superconducting cable cabling equipment is similar to optical cables or cable equipment, and basically comprises a cable core paying-off mechanism 1, a rear traction mechanism 2, a rear wrapping mechanism 3, a twisting mechanism 4, a front wrapping mechanism 5, a front traction mechanism 6 and a take-up mechanism 7 as shown in fig. 1. The cabling method of the set of cabling equipment comprises the steps that a cable core is wound on a disc firstly, is paid out by a cable core paying-off mechanism 1, is positioned by a rear traction mechanism 2 and a rear wrapping mechanism 3, is wound on a superconducting tape by a twisting mechanism 4, is shaped and led out by a front wrapping mechanism 5 and a front traction mechanism 6, and is wound on a disc by a winding mechanism 7 to complete the manufacturing. And if multi-layer twisting is needed, the take-up reel is moved to the paying-off device and is paid out again, and the previous operation steps are repeated to finish the manufacturing process of the superconducting cable.

The existing superconducting cabling equipment has more defects:

from the aspect of cabling process, the superconducting cable is different from a common cable, the structure is complex, the requirement on the manufacturing process is high, the cable core manufacturing needs to be finished in a winding and twisting mode due to the fact that the current carrier is of a belt-shaped structure, and the winding and twisting of the superconducting tape can not be finished at one time. According to different current requirements, the current device can be realized by twisting a plurality of layers of superconducting tapes, the current device can only twist one layer of superconducting tapes, and the multilayer structure needs to be twisted for many times; when the requirement of the insulation grade is higher, a thicker insulation layer needs to be wound, and the factors can cause the outer diameter of the superconducting cable to be larger. According to the accumulated experience, the damage to the superconducting cable by each winding operation of the upper tray is large, and the damage to the electrical performance of the superconducting cable by the wrinkles generated by the bending of the insulating paper and the deformation generated by the bending of the superconducting tape is great. Also empirically, this damage can be mitigated by using a disc with the largest disc diameter, but due to a number of factors, the disc diameter of the disc will not be made larger.

From the equipment composition aspect: the existing cabling equipment is simple in structure, and the equipment cannot meet the requirements after the structure, length or diameter and other parameters of the superconducting cable are changed.

In view of the above problems, no better solution has been provided.

SUMMERY OF THE UTILITY MODEL

Still provide a cable stranding equipment, including as above cable stranding auxiliary transport device and arrange the paying out machine who draws the mechanism outside in the back and arrange the admission machine who draws the mechanism outside in the front in.

The utility model discloses a supplementary conveyer of cable stranding can the reciprocal conveying superconducting cable of circulation, realizes the superconducting cable in the intermediate link that the stranding was made, need not to coil on the wall, alright reciprocal repetitive operation step, the manufacturing process in the middle of accomplishing. The method can avoid the folds and deformation of the superconducting cable insulating layer and the superconducting strip material caused by the repeated coiling and bending, and has better guarantee function on the aspect of ensuring the electrical performance of the superconducting cable. And, because the step of hanging wall winding has been reduced, also need not the manual work and move the take-up reel that coils to pay-off, reduced artifical intensity of labour, also improved the stranding efficiency.
