Abstract
The utility model belongs to power construction appliances especially to a V-shaped pull-bar clamp for live replacement of a great tensioned strain insulator. One ends of three insulating pull plates (1) and one end of a first wire tightening nut (6) are axially fixed at equal intervals through articulated slabs (14) at both ends of a V-shaped clamp (2), and insulator chains (3) are axially installed on V-shaped clamp between each two insulating pull plates (1) through a dual plate (3-1). One end of a second wire tightening nut (6-1) is connected to the other ends of the insulating pull plates (1), and nut connecting plates (8) are arranged on the other ends of the first wire tightening nut (6) and the second wire tightening nut (6-1). A large ratchet (9) is in threaded connection to a wire tightening screw (7) between the two nut connecting plates (8), and a ratchet mounts (11) is arranged under the large ratchet (9) and the nut connecting plates (8) and level to the wire tightening screw (7). A small ratchet (14) with dies (12) is installed on the ratchet mounts (11). The V-shaped pull-bar clamp has better performance, ensures timeliness of unkeeping and reliability of power supply, and improves work efficiency.
