Abstract

The utility model belongs to a special maintenance tool for a power transmission line, which is used for serving as a beam side hanging point when a straight line pole replaces insulator strings and a wire is lifted in a 66KV-220KV line. The 66KV-220KV tip beam universal suspension wire clamping apparatus comprises two opposite clamping plates at an interval; a plurality of bolts are connected between the clamping plates; the middle of the bottom surface of each clamping plate is provided with a clamping groove; upper surfaces at two sides of each clamping plate are respectively provided with grooves; and openings of the grooves are provided with sealing and blocking plates. The span can be changed through changing the bolts, and installation and use on tip beams of various kinds can be met. The structure is simple and reasonable, fixing is reliable, and the use is saved. Wire lifting hanging points in the case when the insulators are placed are provided for various tip straight line beams. Exchange between screw rods and tackles and lifting tools between soft lifting belts can be realized though assembling and disassembling pin rods, and universality of the clamping apparatus can be realized.

Description

The universal messenger wire jig of 66kV-220kV tip cross-arm
Technical field
The utility model belongs to transmission line Special maintenance tool, while changing the lifting of insulator string wire for 66kV-220kV line linear shaft tower as cross-arm side hanging point.It is the universal messenger wire jig of 66kV-220kV tip cross-arm.
Background technology
In the prior art, change in transmission line insulator string replacings that conventionally need to have a power failure, impact production.Also there is the jig of employing as side hanging point, realize live line working.This type of jig also has many forms at home, but does not possess versatility, and often a jig can only use on a kind of cross-arm, need to be equipped with plurality of specifications, with the have more than is needed soft suspender belt of jig or the coaster of screw mandrel, not possess versatility, there is no promotional value, increase recondition expense.
Utility model content
The purpose of this utility model is that a kind of universal messenger wire jig of cross-arm when being applicable to multiple 66kV-220kV tip straight line cross-arm and changing suspension insulator messenger wire is provided for above-mentioned situation.
Technical solution of the present utility model is: the universal messenger wire jig of 66kV-220kV tip cross-arm, comprise two clamps that interval is relative, between clamp, connect by multiple bolts, in the middle of each clamp bottom surface, there is draw-in groove, clamp both sides upper surface is with respectively fluted, and groove notch is with gear shrouding.
Screw rod lifting device is traveled by the groove between clamp; Screw rod lifting device comprises screw mandrel, has nut on screw mandrel, nut two ends with the crossbeam of groove overlap joint, on screw mandrel, cover has lifting handle, screw mandrel lower end is with installing hole.
Can adjust jig span by adjusting bolt, thereby avoid preferably all kinds of cross-arm head bolts, and on yoke plate and crossarm bolt, make it have good stability; Can also be according to the different needs of lifting wire, at jig two ends, hanging point place is directly contained in screw mandrel in hanging groove, with screw mandrel lifting, a pin rod also can be installed in hanging groove, tackle pulley or the soft suspender belt of stringing is hung on pin rod, with coaster or the lifting of soft suspender belt.
The utility model has the advantages that: 1, can change span by adjusting bolt, meet on multiple tip cross-arm and install and use.2, simple and reasonable for structure, fixing reliable, use safety.3, the wire while providing multiple tip straight line cross-arm to change insulator plays sling point.4, the lifting tool that can realize between screw mandrel and tackle pulley and soft suspender belt by mounting or dismounting pin rod exchanges, and has realized the versatility of a jig.
Below in conjunction with accompanying drawing, execution mode of the present utility model is described in further detail.
Brief description of the drawings

Embodiment
Referring to Fig. 1-5, parts title is as follows: clamp 1, bolt 2, draw-in groove 3, groove 4, gear shrouding 5, screw mandrel 6, nut 7, crossbeam 8, lifting handle 9, installing hole 10, cross-arm 11, crossarm bolt 12, insulator hanging point 13.
Referring to Fig. 1,2, the universal messenger wire jig of 66kV-220kV tip cross-arm comprises two clamps 1 that interval is relative, clamp 1 is triangle, between clamp 1, connect by six bolts 2, each clamp has draw-in groove 3 in the middle of 1 bottom surface, it is fluted 4 that clamp 1 both sides upper surface is with respectively, and groove 4 notches are with gear shrouding 5, and gear shrouding 5 is fixed by screw.
Referring to Fig. 3, screw rod lifting device is individual components, is respectively to put one in jig both sides.When use, travel by the groove 4 between clamp 1, across between two clamps 1.Screw rod lifting device comprises screw mandrel 6, has nut 7 on screw mandrel 6, and nut 7 two ends are with the crossbeam 8 overlapping with groove 4, and on screw mandrel 6, cover has lifting handle 9, and screw mandrel 6 lower ends are with installing hole 10.
Referring to Fig. 4,5, be transmission line pylon tip cross-arm, cross-arm 11 is reclined and is formed by angle steel, between fixing by seven crossarm bolts 12.In figure, rectangle dotted line frame is this jig installation site.Groove 4 blocks on the middle stile of cross-arm.Owing to there being four crossarm bolts 12 on cross-arm 11, when jig clamping, to be stuck in the both sides of bolt, on different cross-arms, the spaced apart distance of bolt is different, require the distance between clamp 1 adjustable, so connect by the bolt 2 of two ends band screw thread between two clamps 1, just met on-the-spot instructions for use.Cross-arm universal type fixture when this device is particularly useful for multiple 66kV-220kV tip straight line cross-arm replacing suspension insulator messenger wire.
On cross-arm 11, put this jig, then put screw rod lifting device, and connect upper conductor, rotate lifting handle 9, realize screw mandrel 6 and move up and down, lifting lead wire, is relaxed insulator string, realizes hot-line insulator string replacement.Installing hole 10 connects insulated tension pole, and there is hook insulated tension pole lower end, and hook is hooked on wire and just can have lifted by crane.
Describing above, is embodiment of the present utility model, and various not illustrating is construed as limiting flesh and blood of the present utility model.
