Abstract
The utility model relates to tools of power supply industry, in particular to a high pressure live line insulating ladder, which essentially comprises middle ladders (2), and fixed bolts (5), wherein a fixed bottom ladder (1) is fixed under the several steps of the middle ladders (2) by connecting plates (4) and the fixed bolts (5), a fixed top ladder (3) is fixed on the several steps of the middle ladder (2) by the connecting plates (4) and the fixed bolts (5), the top end of the top ladder takes a triangle shape, a hanger fixed block (8) is fixed in the middle of two support boards (3) on the triangle top end, the hanger fixed block (8) is fixed with a hanger (6) which is movably provided with a pulley (7) through the bolt (5). The high pressure live line insulating ladder with framework structure has excellent stability of connecting mode, strong capability of bearing, convenient mounting and dismounting, and excellent economic benefit, which increases the security of high pressure live line work, and reduces power off frequencies when checking transporting and transforming devices.
Description
Technical field
The utility model belongs to the power supply industry apparatus, particularly a kind of high-voltage live working insulating ladder.
Technical background
Livewire work is a kind of special operation method that power transmission and transforming equipment overhauls under the charging operation state.Owing to there is not special-purpose ladder, common aerial ladder does not possess insulation function again, when once becoming 220 kilovolts of scrap builds, needs bus repeatedly to have a power failure, and brings economic loss for the production in the area that has a power failure, and power worker's work is made troubles and dangerous.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of and can carry out power transmission and transforming equipment easy to use, safe and reliable high-voltage live working insulating ladder when transforming under power-off condition not.
The technical scheme that the utility model technical solution problem adopts is: the high-voltage live working insulating ladder mainly is made up of ladder and bolt in the middle of the number joint, be characterized in the middle of number joint, using below the ladder junction plate to fixedly connected ladder at the bottom of with set bolt, fixedly connected a top ladder with set bolt with junction plate in the above, ladder upper end, top is a triangle, at a hook of apex two pillar plate center fixed fixed block, on the hook fixed block, fix a hook, in hook, adorn a pulley versatilely with bolt.
The beneficial effects of the utility model are: the high-voltage live working insulating ladder is frame construction, connected mode has good stability, weight capacity is big, strengthened the safety of high-voltage hot-line work, assemble, dismantle very convenient, when the maintenance power transmission and transforming equipment, reduced frequency of power cut, reduced the stopping production loss of line loss and electricity consumption enterprise, good economic benefits has been arranged.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 shows high-voltage live working insulating ladder front view.
The vertical view of Fig. 2 diagrammatic sketch 1.
Among the figure, ladder at the bottom of the 1-; Ladder in the middle of the 2-; 2-1-ladder pillar plate; 2-2-ladder beam; 3-pushes up ladder; The 4-junction plate; The 5-set bolt; The 6-hook; The 7-pulley; 8-links up with fixed block;
The specific embodiment
Embodiment: with reference to accompanying drawing 1,2, two lateral brace plate 2-1 of the end ladder 1 of high-voltage live working insulating ladder, middle ladder 2, top ladder 3 all adopt the thick epoxy resin board of 10mm, ladder beam 2-2 with the pillar plate adopt concavo-convex chimeric fixing with brass or stainless steel set bolt 5 and gluing.End ladder 1 is a joint, and middle ladder 2 can adopt more piece according to the height of bus, and top ladder 3 is a joint, and is fixing with junction plate 4 and set bolt 5 between every joint ladder, fixes two ladder beam 2-2 again in the junction, guarantees that ladder beam 2-2 is evenly equidistant.Triangle is made in the upper end of top ladder 3, fixes a hook fixed block 8 with set bolt 5 between the apex pillar plate 2-1, and fixed block 8 adopts composite board to form.Fix one and link up with 6 on fixed block 8, adorn a pulley 7 versatilely with bolt 5 in the middle of hook 6, so that insulating ladder can be free to slide on bus, the high-voltage live working insulating ladder can be dismantled at any time, install, convenient transportation and use.
Claims (1)
1, a kind of high-voltage live working insulating ladder, mainly form by middle ladder (2) and set bolt (5), ladder (1) at the bottom of it is characterized in that in the middle of number joint below the ladder (2) fixing one with junction plate (4) and set bolt (5), in the middle of number joint, fixedly connected a top terraced (3) with bolt (5) with fixed head (4) above the ladder (2), top ladder (3) upper end is a triangle, at a hook of apex two pillar plate (3) center fixed fixed block (8), on hook fixed block (8), fix a hook (6), in hook (6), adorn a pulley (7) versatilely with bolt (5).
