Abstract
The utility model in particular relates to a tool for replacing insulators, which belongs to the transmitting line technical field. The utility model relates to a triangle yoke plate fixing connector, which is characterized in that a first U-shaped socket (3) enclosed by two upper side plates is arranged at the upper part of a connector body (5) bolt holes are respectively arranged at the two upper side plates, a second bolt (2) passes through the bolt holes on the two upper side plates, a second U-shaped socket (4) enclosed by two lower side plates is arranged at the lower part of the connector body (5), bolt holes are respectively arranged at the two lower side plates, and a first bolt (1) passes through the bolt holes on the two lower side plates. The triangle yoke plate fixing connector has the advantages of simple structure and convenient operation.
Description
Technical field
The utility model belongs to the transmission line technical field, is specifically related to a kind of instrument of changing insulator.
Background technology
The double bundle conductor 9 of transmission line is linked to each other with triangle yoke plate 10 (or claiming connecting plate) lower end by wire clamp, and the upper end of triangle yoke plate 10 is linked to each other with line insulator 6 by lock, and line insulator 6 is suspended on the iron tower support.Line insulator is the important component part of transmission line, when needs overhaul, needs triangle yoke plate 8 is held up, and lock is extracted, and triangle yoke plate 8 is separated with line insulator, and line insulator is overhauled (containing replacing).At present, be equipotential operation maintenance line insulator, can not realize charged indirect operation maintenance (containing replacing) line insulator.
Summary of the invention
The purpose of this utility model is to provide a kind of triangle yoke plate permanent joint simple in structure, easy to use.
To achieve these goals, the technical solution of the utility model is: triangle yoke plate permanent joint, it is characterized in that: the top of fittings body 5 is that two epipleurals surround on the first U-shaped socket, 3, two epipleurals and are respectively equipped with screw, and second bolt 2 penetrates the screw on two epipleurals; The bottom of fittings body 5 is that two lower side panels surround on the second U-shaped socket, 4, two lower side panels and are respectively equipped with screw, and first bolt 1 penetrates the screw on two lower side panels.
The beneficial effects of the utility model are: adopt said structure, it is simple in structure, adopts the socket connected mode, and is easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the right view of Fig. 1
Fig. 3 is a user mode schematic diagram of the present utility model
Among the figure: 1-first bolt, 2-second bolt, the 3-first U-shaped socket, the 4-second U-shaped socket, 5-fittings body, 6-insulator, the 7-arm-tie that insulate, 8-triangle yoke plate permanent joint, 9-lead, 10-triangle yoke plate.
Embodiment
Embodiment 1:
As shown in Figure 1, triangle yoke plate permanent joint, the top of fittings body 5 is that two epipleurals surround on the first U-shaped socket, 3, two epipleurals and are respectively equipped with screw, second bolt 2 penetrates the screw on two epipleurals; The bottom of fittings body 5 is that two lower side panels surround on the second U-shaped socket, 4, two lower side panels and are respectively equipped with screw, and first bolt 1 penetrates the screw on two lower side panels.
Two epipleurals become 90 degree with the arranged direction of two lower side panels.Be the inclined-plane at the bottom of the U-shaped of the second U-shaped socket 4, adapt with the inclined-plane of triangle yoke plate.
Change insulator: as shown in Figure 2, the second U-shaped socket 4 of 2 triangle yoke plate permanent joints 8 is passed triangle yoke plate 10 (triangle yoke plate 10 inserts in the second U-shaped socket 4), screwing in 2,2 triangle yoke plates of second bolt permanent joint 8 then is fixed on the triangle yoke plate 10.The insulator string that lifting device is fixed on iron tower cross-arm hanging wire point place connects on gold utensil U type ring or the right angle link plate, 2 insulation arm-ties 7 of lifting device insert respectively in the first U-shaped socket 3 of 2 triangle yoke plate permanent joints 8, screwing in 1,2 triangle yoke plate of first bolt permanent joint 8 then is fixed on 2 insulation arm-ties 7 of lifting device; Regulate the screw mandrel of lifting device, triangle yoke plate 10 is to an end motion of insulator 6, triangle yoke plate 10 is tightened up, insulator string tension force is transferred on two insulation arm-ties, make insulator string 6 keep relaxed state, lock is extracted, triangle yoke plate 8 is separated with line insulator, line insulator is overhauled (containing replacing).
