Title:
EXTERNAL ELECTRIC GEAR DOUBLE-LOCKING RATCHET-TYPE WIRE GRIP FOR INDIRECT LIVE LINE, AND INDIRECT LIVE LINE CONSTRUCTION METHOD FOR SAGGING ADJUSTMENT, TENSIONING WORK, AND SUSPENSION INSULATOR REPLACEMENT USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/206297
Kind Code:
A1
Abstract:
The present invention relates to a wire grip for an indirect live line and, more specifically, to an external electric gear double-locking ratchet-type wire grip for an indirect live line and an indirect live line construction method for sagging adjustment, tensioning work, and suspension insulator replacement using same, the wire grip: completely blocking, during one-directional rotation, the rotation of a cam driveshaft in the other direction through a pair of ratchets on both sides responding by means of a direction-changing lever operation, so as to provide, for winding- or unwinding-forward rotation of a drum around which a belt is wound, a convenient drum rotation operation enabling winding- or unwinding forward rotation of the drum with only the rotation of the cam driveshaft in the one direction, and the like; completely blocking, during one-directional rotation, the rotation of the cam driveshaft in the other direction through the pair of ratchets on both sides, so as to ensure work stability and convenience of stopping such as the complete blocking of reverse rotation of the drum when not in use; and enabling an operator to use a live-line work stick so as to operate a direction-changing lever and drive the cam driveshaft having a hook, and thus enables, through indirect live-line work, safe and uninterruptible work, such as sagging adjustment, tensioning work, and suspension insulator replacement for an electric line, at a long distance from the electric line in a live-line state.
