A pre-twisted wire winding tool and winding method for repairing power transmission wires

Abstract

The present invention discloses a pre-twisted wire winding tool and a winding method for repairing power transmission wires and belongs to the field of power machinery. The pre-twisted wire winding tool comprises an outer half module, an inner half module in matched connection with a groove on the inner sidewall of the outer half module, and a plurality of the handles uniformly distributed on the outer sidewall of the outer half module. According to the technical scheme of the invention, based on the cooperation of the outer half module with the inner half module, the handles on the outer ring of the outer half module are rotated to wind a pre-twisted wire around a broken power transmission wire. Especially, when the tail end of the pre-twisted wire is to be wire around the broken power transmission wire by the pre-twisted wire winding tool, the operation is more time-saving and more labor-saving compared with the manually winding manner in the prior art. In this way, not only the working strength of operators is reduced, but also the working efficiency of operators is improved obviously. Meanwhile, the gaps of intertwined pre-twisted wires can be reduced during the rotating and winding process of pre-twisted wires by means of the tool. Moreover, the process quality is improved.

Description

technical field [0001] The invention belongs to the field of electric machinery, and in particular relates to a pre-twisted wire winding tool and a winding method for repairing power transmission wires. Background technique [0002] Transmission lines are exposed to the wild for a long time, and when the wires and ground wires are subjected to external forces such as lightning strikes, they are prone to strand breakage. However, on the premise of meeting the requirements of substation operation regulations, most of the treatment methods are pre-twisted wire winding reinforcement. [0003] Pre-twisted winding of broken strand wires and broken strand ground wires requires short operation time and high process quality; however, in actual field operations, the artificially wound pre-twisted wires have a large gap and low process quality, often Restricting the successful completion of the emergency repair work, especially when dealing with the broken strands of the optical cable ...

Problems solved by technology

[0003] Pre-twisted winding of broken strand wires and broken strand ground wires requires short operation time and high process quality; however, in actual field operations, the artificially wound pre-twisted wires have a large gap and low process quality, often Restricting the successful completion of the emergency repair work, especially when dealing with the broken strands of the optical cable (conductor), there is also a hidden danger of damaging the optical cable (conductor) when the screwdriver (tool) used is held back. There are many and have a certain strength, and some are not easy to wind by hand, especially at the end, it is more laborious, resulting in time-consuming and labor-intensive, low work efficiency and high labor intensity in the process of winding pre-twisted wire, so it needs to be Development and research of a pre-twisted wire winding tool
