Abstract
The utility model relates in a kind of electric transmission line hot-line service work changes that same tower is two, many times tangent tower insulator string devices, more particularly, relates to double loop tangent tower steeple head cross-arm jig.Jig body is made up of left and right two points of cards, each point of card is arranged respectively an adjustable pole hook and a load screw mandrel, and two points of cards adopt symmetrical expression to connect, and are linked together by the first adjustable apparatus set bolt; Load screw mandrel is positioned at the two ends of jig body, and adjustable pole hook is between two load screw mandrels.The utility model solves in electric transmission line hot-line service work, to change that 110kV is two, in the operation of multi-loop tangent tower steeple head insulator string because the restricted problem of carrying out that wire diameter and hoist load work to this.
Description
Technical field
The utility model relates in a kind of electric transmission line hot-line service work changes that same tower is two, many times tangent tower insulator string devices, more particularly, relates to double loop tangent tower steeple head cross-arm jig.
Background technology
In the work of current power transmission circuit hotline maintenance, on 110kV transmission line, when turriform is steel tube tower multi-loop tangent tower steeple head square cross-arm structure, because tower head is special and do not have corresponding live line working special mould clamp, limit and change that 110kV is two with tower, the carrying out of many times tangent tower insulator string live line working work.
Summary of the invention
The utility model, just for the problems referred to above, provides a kind of double loop tangent tower steeple head cross-arm jig.To achieve these goals, the utility model adopts following technical scheme, jig body is made up of left and right two points of cards, each point of card is arranged respectively an adjustable pole hook and a load screw mandrel, two points of cards adopt symmetrical expression to connect, and are linked together by the first adjustable apparatus set bolt; Load screw mandrel is positioned at the two ends of jig body, and adjustable pole hook is between two load screw mandrels.Adjustable pole hook is fixed in jig body by the second adjustable apparatus set bolt, and two heads hooked are relative.Load screw mandrel is fixed in jig body by load screw mandrel set bolt
.
the beneficial effects of the utility model:
The utility model solves in electric transmission line hot-line service work, to change that 110kV is two, in the operation of multi-loop tangent tower steeple head insulator string because the restricted problem of carrying out that wire diameter and hoist load work to this; Solving circuit turriform is that the width of steel pipe tangent tower steeple head square cross-arm differs, and installs the problem of fixing difficulty; Solve Work tool after load, easily outer sliding, easily cause wire to lift by crane stressed rear skew, not enough to the safe distance of tower body, produce the problem of serious accident; Solve and adopt under single suspension centre lifting method, the accident of landing for avoiding producing serious live wire must take to prevent the problem of the back measure of wire slippage.Acted freely by screw mandrel lifting, whereabouts wire, coordinate without the need to ground staff, time saving and energy saving, simplify work, and improve the fail safe of operation, reduce the labour intensity of personnel.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.In Fig. 1,1 is jig body, and 2 is the first adjustable apparatus set bolt, and 3 is adjustable pole hook, and 4 is the second adjustable apparatus set bolt, and 5 is load screw mandrel, and 6 is load screw mandrel set bolt.Fig. 2 is the vertical view of Fig. 1.In Fig. 2,1 is jig body, and 2 is the first adjustable apparatus set bolt, and 3 is adjustable pole hook, and 4 is the second adjustable apparatus set bolt
.
embodiment:
From Fig. 1-2, jig body of the present utility model is made up of left and right two points of cards, each point of card is arranged respectively an adjustable pole hook and a load screw mandrel, two points of cards adopt symmetrical expression to connect, and are linked together by the first adjustable apparatus set bolt; Load screw mandrel is positioned at the two ends of jig body, and adjustable pole hook is between two load screw mandrels.Adjustable pole hook is fixed in jig body by the second adjustable apparatus set bolt, and two heads hooked are relative.Load screw mandrel is fixed in jig body by load screw mandrel set bolt.During use, by adjusting the width of the adjustable tower body fixture of jig body, jig being fixed on steeple head cross-arm, the load screw mandrel at the good jig two ends of assembly and connection, then being connected with connector, arm-tie, line lifter etc.Tighten up in tower head side and loosen screw mandrel, completing the work changing insulator string.Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept, the various modification that this area ordinary person makes the technical solution of the utility model and improvement, all should drop into protection range of the present utility model.
