Abstract
The utility model relates in a kind of electric transmission line hot-line service work changes that same tower is two, many times straight line steel tube tower insulator string devices, more particularly, relates to straight line steel tube tower side, double loop cross-arm jig.Comprise jig body, two adjustable pole hooks and two load screw mandrels, two load screw mandrels are set in parallel in the two ends of jig body, and vertical with jig body, and two adjustable pole hooks are between two load screw mandrels, and parallel with load screw mandrel.
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 straight line steel tube tower insulator string devices, more particularly, relates to straight line steel tube tower side, double loop cross-arm jig.
Background technology
In the work of current power transmission circuit hotline maintenance, on 110kV-220kV transmission line, when tower is steel tube tower multiloop straight line steel tube tower 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-220kV is two with tower, the carrying out of many times straight line steel tube tower insulator string live line working work.
Summary of the invention
The utility model, just for the problems referred to above, provides straight line steel tube tower side, a kind of double loop cross-arm jig.To achieve these goals, the utility model adopts following technical scheme, comprise jig body, two adjustable pole hooks and two load screw mandrels, two load screw mandrels are set in parallel in the two ends of jig body, and it is vertical with jig body, two adjustable pole hooks are between two load screw mandrels, and parallel with load screw mandrel.Two adjustable pole hooks are identical with the symmetry axis of two load screw mandrels in jig body.Adjustable pole hook is fixed in jig body by adjustable apparatus set bolt, and two heads hooked are relative.Load screw mandrel is fixed in jig body by load screw mandrel set bolt.Adjustable pole hook upper end is provided with screw thread
.
the beneficial effects of the utility model:
The utility model is owing to have employed adjustable tower body fixture, solve in electric transmission line hot-line service work, in replacing 110-220kV pair, the operation of multiloop straight line steel tube tower square cross arm 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 straight line steel tube tower 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 adjustable pole hook, and 3 is adjustable apparatus set bolt, and 4 is load screw mandrel, and 5 is load screw mandrel set bolt.
embodiment:
As shown in Figure 1, the utility model comprises jig body, two adjustable pole hooks and two load screw mandrels, and two load screw mandrels are set in parallel in the two ends of jig body, and vertical with jig body, two adjustable pole hooks are between two load screw mandrels, and parallel with load screw mandrel.Two adjustable pole hooks are identical with the symmetry axis of two load screw mandrels in jig body.Adjustable pole hook is fixed in jig body by adjustable apparatus set bolt, and two heads hooked are relative.Load screw mandrel is fixed in jig body by load screw mandrel set bolt.Adjustable pole hook upper end is provided with screw thread.During use, by adjusting the width of the adjustable pole hook fixture of jig, jig being fixed on square 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.
