Abstract
The utility model belongs to the field of live power maintenance tools, and particularly relates to a horizontal ladder for entering an electric field in a swinging way. A pulling lug (11) is welded on the upper part of one end of an insulator horizontal ladder (2). The other end of the insulator horizontal ladder (2) is fixed on a triangular support (3) through a bolt (1). A cross arm (12) on the triangular support (3) is fixed on a rotating lug (5) through a nut (6). The rotating lug (5) is movably connected with a bracket (4). The bracket (4) is welded on a vertical angle steel clamp (7). A clamping hook is arranged at the upper end of the vertical angle steel clamp (7). A horizontal bolt (8) is fixed at the lower end of the vertical angle steel clamp (7). A horizontal angle steel clamp (9) is sleeved on the horizontal bolt (8), and is fixed by a nut (10). By the horizontal ladder, the limitation that staff cannot enter a middle phase or an upper phase by a rope ladder is broken; and the horizontal ladder has a simple structure, and is convenient to use, flexible in operation and universal.
Description
One, technical field:
The utility model belongs to electric power hotline maintenance field of tool, and the flat ladder of electric field is advanced in particularly a kind of swing.
Two, background technology:
Electric power overhaul advanced electric field in the past; The rope ladders that adopt more; Rope ladder advances electric field can only carry out the single loop limit and reach mutually and advance the electric field operation under the double loop mutually, can't centering mutually or on carry out operation mutually, and the equipotential personnel to climb the rope ladder physical demands big; Inefficiency, existing rope ladder can't satisfy the requirement of electric power maintenance.
Three, summary of the invention:
The utility model is exactly to get into the problem that electric field exists to existing equipotential personnel, has designed the flat ladder that electric field is advanced in a kind of swing.The utility model is achieved in that a kind of swing advances the flat ladder of electric field, and an end top that it is characterized in that the flat ladder of isolator (2) is welded with draws ear (11); The other end of the flat ladder of isolator (2) is fixed on the tripod (3) with bolt (1); Transverse arm (12) on the tripod (3) is fixed on the transfer ear (5) with nut (6), and transfer ear (5) flexibly connects with support (4), and support (4) is welded on the vertical angle steel card (7); There is a trip upper end of vertical angle steel card (7); A transverse bolt (8) is fixed in the lower end of vertical angle steel card (7), is with cross level angle steel card (9) on the transverse bolt (8), and cross level angle steel card (9) is fixing with nut (10).The utility model is to use like this; The trip of vertical angle steel card (7) is hung on the electric power tower, be stuck on the electric power tower, fastening nut (10) with cross level angle steel card (9); The utility model just has been fixed on the electric power tower; Equipotential staff gets into flat ladder, and the insulation rope that draws ear (1) is passed in earth potential staff pulling, and just can make the flat ladder of isolator (2) is that the axle center horizontally rotates with transfer ear (5); Equipotential staff just gets into electric field smoothly, fast, and the earth potential staff will be insulated to restrict to be fixed on the iron tower again and got final product.Adopt flat terraced swing method to carry out operation, equipotential personnel have guaranteed that not only the equipotential live line work personnel can get into operating location fast, and have guaranteed that the equipotential live line work personnel have enough working spaces through insulated ladder turnover electric field.The utility model has solved during the rope ladder method can't get into mutually or has gone up the limitation of phase, and simple in structure, easy to use, flexible operation, and have versatility.
Four, description of drawings:
Fig. 1 is the utility model structural representation
Fig. 2 is Figure 1A-A sectional view
Among the figure: 1, bolt 2, isolator are put down ladder 3, tripod 4, support 5, transfer ear 6, nut 7, vertical angle steel card 8, transverse bolt 9, cross level angle steel card 10, nut 11, are drawn ear 12, transverse arm
Five, the specific embodiment:
Embodiment 1: the flat ladder of electric field is advanced in a kind of swing; One end top of the flat ladder of isolator (2) is welded with draws ear (11), and the other end of the flat ladder of isolator (2) is fixed on the tripod (3) with bolt (1), and the transverse arm (12) on the tripod (3) is fixed on the transfer ear (5) with nut (6); Transfer ear (5) flexibly connects with support (4); Support (4) is welded on the vertical angle steel card (7), and there is a trip upper end of vertical angle steel card (7), and a transverse bolt (8) is fixed in the lower end of vertical angle steel card (7); Be with cross level angle steel card (9) on the transverse bolt (8), cross level angle steel card (9) is fixing with nut (10).
Claims (1)
1. the flat ladder of electric field is advanced in a swing; An end top that it is characterized in that the flat ladder of isolator (2) is welded with draws ear (11), and the other end of the flat ladder of isolator (2) is fixed on the tripod (3) with bolt (1), and the transverse arm (12) on the tripod (3) is fixed on the transfer ear (5) with nut (6); Transfer ear (5) flexibly connects with support (4); Support (4) is welded on the vertical angle steel card (7), and there is a trip upper end of vertical angle steel card (7), and a transverse bolt (8) is fixed in the lower end of vertical angle steel card (7); Be with cross level angle steel card (9) on the transverse bolt (8), cross level angle steel card (9) is fixing with nut (10).
