Abstract
The utility model discloses a temporary support cross arm for hot-line work. The temporary support cross arm comprises a fixing rod provided with a fixing base. The fixing base is provided with a central supporting column. The central supporting column is provided with a plurality of adjusting holes and is provided with a moving sliding block through a lock catch bolt. Two symmetric insulating arms are hinged on the moving sliding block. Middle portions of the two symmetric insulating arms are respectively connected with top ends of the central supporting column through two connecting rods. One end of each connecting rod is hinged with one insulating arm, and the other end of each connecting rod is hinged with the central supporting column. The top end of the central supporting column and top ends of the insulating arms are all provided with guide line fixing grooves. The temporary support cross arm is simple and easy to install, low in cost, light in weight, easy to carry, convenient to operate, and good in economic benefit.
Description
Technical field
The utility model relates to the distribution line live working field, is specially a kind of livewire work temporary supporting cross-arm.
Background technology
The 10kV distribution network is direct user oriented electric power facility, and for improving distribution network reliability of operation, economy, each power supply unit has extensively been carried out distribution network live line work.The comparatively complicated area for landform, aerial lift device with insulated arm is difficult to close, adopts aerial lift device with insulated arm working system poor effect, thereby often adopts the earth potential working method.And live-wire work insulating cross arm or the structure used at present are single, can not adapt to miscellaneous stringing mode; Or lifting wire modulability is poor, operating personnel's labour intensity is larger.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, stringing mode that can adapt to different electric poles and not only laborsaving but also simple livewire work temporary supporting cross-arm in order to overcome above-mentioned deficiency.
The utility model comprises the fixed bar that is provided with firm banking, described firm banking is provided with centre strut, described centre strut is provided with a plurality of adjustment holes, be provided with moving slider by the snap close bolt on described centre strut, be hinged with the insulation arm of two symmetries on described moving slider, the middle part of the insulation arm of described two symmetries is connected with the top of centre strut by two connecting rods respectively, one end and the insulation arm of described connecting rod are hinged, the other end and centre strut are hinged, and the top of described centre strut and insulation arm is equipped with the wire holddown groove.
Also be provided with leading screw between described firm banking and centre strut, described leading screw is provided with the adjusting spanner.
Described firm banking is provided with four screws.
The utility model is provided with moving slider and adjustment hole on centre strut, can change height and the level interval of three wire holddown grooves by regulating moving slider, can adapt to the 10kV electric pole cross-arm width of different size.And be provided with adjusting spanner and leading screw, and can lift by crane the wire of support by regulating spanner, modulability is strong, not only laborsaving but also simple.In addition the utility model install simple and easy, cost is low, lightweight, portable, easy to operate, on the 10kV overhead distribution, use, can greatly improve safety and the operating efficiency of livewire work, reduce operating personnel's labour intensity, there is good economic benefit.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Further illustrate the utility model below in conjunction with drawings and Examples.
Embodiment: the utility model comprises the fixed bar 1 that is provided with firm banking 10, described firm banking 10 is provided with centre strut 2, described centre strut 2 is provided with ten adjustment holes 11, be provided with moving slider 4 by snap close bolt 3 on described centre strut 2, be hinged with the insulation arm 5 of two symmetries on described moving slider 4, the middle part of the insulation arm 5 of described two symmetries is connected with the top of centre strut 2 by two connecting rods 6 respectively, one end and the insulation arm 5 of described connecting rod 6 are hinged, the other end and centre strut 2 are hinged, the top of described centre strut 2 and insulation arm 5 is equipped with wire holddown groove 7.Also be provided with leading screw 8 between described firm banking 10 and centre strut 2, described leading screw 8 is provided with regulates spanner 9.Described firm banking 10 is provided with four screws 12.
During use, described firm banking 10 is clamped on electric pole by anchor ear, then unclamp snap close bolt 3, because moving slider 4 can slide up and down along centre strut 2, vertical height and the level interval of by connecting rod 6, regulating two insulation arms 5, slip moving slider 4 is adjusted insulation arm 5 to correct position, with screwing snap close bolt 3, with adjustment hole 11, matches insulation arm 5 is fixing.Then three-phase conducting wire is put to corresponding wire holddown groove 7, rotated and regulate spanner 9, control leading screw 8 rise and fall, thereby adjusting centre strut 2 and two insulation arms 5 rise overally and descend, and slowly support three-phase conducting wire.The charged for replacement operation of cross-arm, insulator etc. can have been carried out with that.
