Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric power construction tools, in particular to an insulating wire tightener for electric power construction. Background Art
[0002] The wire tensioner, also called ratchet tensioner, is used to tighten the wire during the construction of overhead line installation. When using it, first loosen the wire rope or galvanized iron wire on the wire tensioner and fix it on the crossarm, clamp the wire with the wire clamp, and then turn the special wrench. Due to the anti-reversal effect of the ratchet, gradually wind the wire rope or galvanized iron wire around the ratchet drum to tighten the wire. Fix the tightened wire on the insulator. Then loosen the ratchet first to loosen the wire rope or galvanized iron wire, then loosen the wire clamp, and finally wind the wire rope or galvanized iron wire around the ratchet drum.
[0003] The existing insulating tensioners still have the following problems when in use: most of them adopt a single ratchet structure design. When the tensioner is locking and limiting, the friction loss is large when the teeth of the single ratchet structure are subjected to force. At the same time, if the tooth structure of the single ratchet is damaged, the tensioning work cannot be performed. Utility Model Content

The limiting mechanism is limitatively connected to the ratchet body 14 on the corresponding side. The whole is provided with a symmetrically arranged ratchet mechanism. The two ratchet mechanisms are cooperated with two fixedly designed ratchet jackets 13. Compared with a single ratchet mechanism, when the two sets of ratchet mechanisms are performing the tightening work of the insulating tensioner, the two sets of ratchet mechanisms at both ends are subjected to force at the same time and evenly, and compared with a single ratchet mechanism under the same working conditions, the two ratchets share the friction loss, and the friction loss is smaller.
