Abstract
The utility model relates to a live lead wire fixing insulation cross arm and belongs to the machinery field. The live lead wire fixing insulation cross arm comprises a cross arm body. A hoop is disposed in the middle of the cross arm body. Two ends of the cross arm body are hinged to a cross arm hands. Clips are fixed to the cross arm hands. The live lead wire fixing insulation cross arm is safe and convenient.
Description
Technical field
The utility model relates to a kind of band electrical lead fixed insulation cross-arm, belongs to mechanical field.
Background technology
Livewire work place is generally electric pole or shaft tower top, belongs to work high above the ground, and high-altitude insulator bearing wire is intricate, and while especially joint using many times wires, working space is more narrow.In the work of charged disconnecting wire, the cable tail of cutting off is generally directly suspended on aerial, do not take fixation, this working method is very dangerous in actual job, charged power cable floats and aloft arbitrarily swings, when set up power circuit more complicated time, very easily there is the perils such as line short or ground connection, affect operating efficiency, threaten livewire work personnel's life security.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: the band electrical lead fixed insulation cross-arm that a kind of safe ready is provided.
Band electrical lead fixed insulation cross-arm described in the utility model, comprises cross-arm body, and anchor ear is established at cross-arm body middle part, the hinged cross-arm arm in cross-arm body two ends, fixing clip on cross-arm arm.
Cross-arm body and cross-arm arm are engineering plastics material, not only insulate but also are not easy distortion.
Cross-arm body and cross-arm arm are by bolted splice, and cross-arm arm can come shift position by rotation, prevent from hindering service worker operation.
On cross-arm arm, establish wire fixed via, through wire fixed via, establish screwed hole, in screwed hole, be fixed bolt.
Operating principle and process:
During work, first anchor ear is fixed on electric pole, when operating personnel operate, if live wire end is fixed in short-term, live wire end can be fixed with clip; If need long-term fixing, set bolt is backed out, live wire end is stretched in wire fixed via, then tighten set bolt, by set bolt, wire is pressed in wire fixed via, if cross-arm arm hinders operating personnel's work, the bolt of pin joint is unscrewed, rotation cross-arm arm, to clear position, then tights a bolt.
The beneficial effect that the utility model compared with prior art had is:
Band electrical lead fixed insulation cross-arm described in the utility model, can prevent that unsettled live wire from arbitrarily swinging, and effectively prevents the generation of the perils such as power circuit paragraph or ground connection, guarantees livewire work personnel's safety.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment schematic diagram.
In figure: 1, cross-arm arm; 2, set bolt; 3, fixed via; 4, clip; 5, cross-arm body; 6, anchor ear.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, band electrical lead fixed insulation cross-arm described in the utility model, comprises cross-arm body 5, and anchor ear 6 is established at cross-arm body 5 middle parts, the cross-arm body 5 hinged cross-arm arms 1 in two ends, fixing clip 4 on cross-arm arm 1.
Cross-arm body 5 and cross-arm arm 1 are engineering plastics material, not only insulate but also are not easy distortion.
Cross-arm body 5 and cross-arm arm 1 are by bolted splice, and cross-arm arm 1 can come shift position by rotation, prevent from hindering service worker operation.
On cross-arm arm 1, establish wire fixed via 3, through wire fixed via 3, establish screwed hole, in screwed hole, be fixed bolt 2.
Operating principle and process:
During work, first anchor ear 6 is fixed on electric pole, when operating personnel operate, if live wire end is fixed in short-term, can live wire end is fixing with clip 4; If need long-term fixing, set bolt 2 is backed out, live wire end is stretched in wire fixed via 3, then tighten set bolt 2, by set bolt 2, wire is pressed in wire fixed via 3, if cross-arm arm 1 hinders operating personnel's work, the bolt of pin joint is unscrewed, rotation cross-arm arm 1, to clear position, then tights a bolt.
Claims (4)
