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 distribution line live working field, be specially a kind of livewire work temporary support cross-arm.
Background technology
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 carried out distribution network live line work.For the area that landform is comparatively complicated, aerial lift device with insulated arm is difficult to close, adopts aerial lift device with insulated arm working system poor effect, thus often adopts earth potential working method.And the live-wire work insulating cross arm used at present or structure single, miscellaneous stringing mode can not be adapted to; Or lifting wire modulability is poor, the labour intensity of operating personnel is larger.
Summary of the invention
The object of the invention is to provide that a kind of structure is simple to overcome above-mentioned deficiency, the stringing mode that can adapt to different electric pole and not only laborsaving but also simple livewire work temporary support cross-arm.
The present invention includes the fixed bar being provided with firm banking, described firm banking is provided with centre strut, described centre strut is provided with multiple adjustment hole, described centre strut is provided with moving slider by snap close bolt, described moving slider is hinged with two symmetrical insulation arms, the middle part of described two symmetrical insulation arms is connected with the top of centre strut respectively by two connecting rods, one end and the insulation arm of described connecting rod are hinged, the other end and centre strut hinged, the top of described centre strut and insulation arm is equipped with wire holddown groove.
Also be provided with leading screw between described firm banking and centre strut, described leading screw is provided with adjustment spanner.
Described firm banking is provided with four screws.
The present invention is provided with moving slider and adjustment hole on centre strut, by the height and the level interval that regulate moving slider can change three wire holddown grooves, can adapt to the 10kV pole arm width of different size.And be provided with adjustment spanner and leading screw, by the wire regulating spanner can lift by crane support, modulability is strong, not only laborsaving but also simple.In addition the present invention install simple and easy, cost is low, lightweight, portable, easy to operate, 10kV overhead distribution uses, greatly can improve safety and the operating efficiency of livewire work, reduce the labour intensity of operating personnel, there is good economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
The present invention is further illustrated below in conjunction with drawings and Examples.
Embodiment: the present invention includes the fixed bar 1 being 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, described centre strut 2 is provided with moving slider 4 by snap close bolt 3, described moving slider 4 is hinged with two symmetrical insulation arms 5, the middle part of described two symmetrical insulation arms 5 is connected with the top of centre strut 2 respectively by two connecting rods 6, one end and the insulation arm 5 of described connecting rod 6 are hinged, the other end and centre strut 2 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 and regulates spanner 9.Described firm banking 10 is provided with four screws 12.
During use, described firm banking 10 is clamped on utility poles by anchor ear, then snap close bolt 3 is unclamped, because moving slider 4 can centrally slide up and down by pillar 2, vertical height and the level interval of two insulation arms 5 is regulated by connecting rod 6, slip moving slider 4 adjusts insulation arm 5 to correct position, to match to be fixed by insulation arm 5 with screwing snap close bolt 3 with adjustment hole 11.Then three-phase conducting wire is put in the wire holddown groove 7 of correspondence, rotate and regulate spanner 9, control leading screw 8 rise and fall, thus regulate centre strut 2 and two insulation arms 5 to rise overally and decline, slowly support three-phase conducting wire.The charged for replacement operation of cross-arm, insulator etc. can be carried out with that.
