Abstract
The invention discloses a temporary supporting crossarm for living working, which comprises a fixed rod with a fixed base. The fixed base is provided with a centre strut; the centre strut is provided with a plurality of regulating holes; a moving sliding block is arranged on the centre strut by a lock catch bolt; the moving sliding block is hinged with two symmetrical insulating arms; the middle parts of the two symmetrical insulating arms are respectively connected with the top end of the centre strut by two connecting rods; one ends of the connecting rods are hinged with the insulating arms and the other ends of the connecting rods are hinged with the centre strut; and the top ends of the centre strut and the insulating arms are all provided with wire fixing grooves. The temporary supporting crossarm for living working is simple and easy to install, low in cost, light in weight, easy to carry and convenient to operate and has excellent economic benefits.
Description
Technical field
The present invention relates to the distribution line live working field, be 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.For the comparatively complicated area of 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, and operating personnel's labour intensity is larger.
Summary of the invention
The objective of the invention is provides 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 present invention includes 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 the described centre strut, be hinged with the insulation arm of two symmetries on the described moving slider, the middle part of the insulation arm of described two symmetries links to each other 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 the centre strut, described leading screw is provided with the adjusting spanner.
Described firm banking is provided with four screws.
The present invention is provided with moving slider and adjustment hole at 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, and is not only laborsaving but also simple.In addition the present invention install simple and easy, cost is low, lightweight, portable, easy to operate, use at the 10kV overhead distribution, can greatly improve safety and the operating efficiency of livewire work, reduce operating personnel's labour intensity, have good economic benefit.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Further specify the present invention below in conjunction with drawings and Examples.
Embodiment: the present invention includes 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 the described centre strut 2, be hinged with the insulation arm 5 of two symmetries on the described moving slider 4, the middle part of the insulation arm 5 of described two symmetries links to each other 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, and 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 the 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 the 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 level interval by connecting rod 6 adjustings two insulation arms 5, slip moving slider 4 is adjusted insulation arm 5 to correct position, matches insulation arm 5 is fixing with adjustment hole 11 with screwing snap close bolt 3.Then three-phase conducting wire is put to the wire holddown groove 7 of correspondence, rotated and regulate spanner 9,8 rise and fall of control leading screw, thus 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.
