Abstract
The utility model relates to an insulating ladder. The insulating ladder comprises a ladder body, wherein supporting rods are installed on two sides of the lower part of the ladder body respectively; the upper end of the supporting rod is hinged with the ladder body; the lower part of the supporting rod is hinged with the ladder body through a limiting component; the limiting component adopts a limiting pull rod, a limiting pull cable, or a combination of the limiting pull rod and the limiting pull cable; an antislip strip is fixed installed on a ladder body overlapping working surface which is positioned within a range of 1m from the top end of the ladder body; and the antislip strip is made of hard plastic. The insulating ladder has the advantages of simple and reasonable structure, capability of effectively preventing downward slippage, side slippage and other dangers of the insulating ladder during use, manpower conservation, safety and reliability.
Description
Technical field
The utility model relates to a kind of insulating ladder.
Background technology
Mainly high-rise working use when power system device overhauls of insulating ladder.All be positioned at the position higher apart from ground by maintenance equipment such as outdoor transformer, mutual inductor etc., and the shell of these electric fixturess is that metal material is made, smooth surface makes insulating ladder take by unstable, easily glides, breaks away; In addition, the equipment availability face that has is narrow and small, and only about 60cm, above ladder rode over, two back gauges were very narrow as the mutual inductor width, and work overexerts if the operating personnel stands in the top, and insulating ladder just has the danger of breakking away takes place.For preventing above potential safety hazard, when operation, need two hand steered firmly ladder both sides of personnel usually, this mode has been wasted manpower greatly, and and unreliable.
The utility model content
Technical problem to be solved in the utility model provides a kind of taking and leans on firmly, prevents that the insulating ladder of sideslip downslide is to overcome the deficiencies in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is:
Insulating ladder comprises terraced body, and both sides, described terraced body bottom are separately installed with a support bar, and this post upper and terraced body are hinged, and the bottom is hinged by a spacing member and terraced body.
Described post upper is positioned at the terraced body of distance bottom 60-80 centimeters in ladder installation site on one's body.
A kind of for for limit pull rod or spacing drag-line of described spacing member, perhaps its two combination.
Described spacing member is a limit pull rod, and this limit pull rod is made up of the two one hinged each other connecting rods of end.
On the terraced body overlap joint work plane in the 1 meter scope in distance terraced body top, also be installed with reeding, this reeding adopts hard plastics to make.
The obtained technological progress of the utility model is: simple and reasonable, owing on the overlap joint work plane of terraced body, reeding is installed, increased and the coefficient of friction that is overlapped the repair apparatus metal surface, and make that the insulating ladder overlap joint is firm, be difficult for producing downslide; Be provided with support bar in terraced body bottom, increased the strong point of insulating ladder, effectively prevented the sideslip of insulating ladder, the support bar bottom is hinged by the limit pull rod that is made of the two one hinged each other connecting rods of end and insulating ladder ladder body, can be optionally during operation folding and unfolding support bar at any time; This insulating ladder is specially adapted to use when insulating ladder can't colligation and can't be implemented the place operation of other reliable and secure measure, saves manpower, and is safe and reliable.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 places the status architecture schematic diagram for the utility model support bar.
The specific embodiment
The utility model is described in further detail below with reference to accompanying drawing and embodiment: as shown in Figure 1 and Figure 2, insulating ladder comprises terraced body 1, two lateral extents ladder body bottom, described terraced body 1 bottom, 70 centimeters, be separately installed with a support bar 3, these support bar 3 upper ends and terraced body 1 are hinged, the bottom is hinged by spacing member 4 and the terraced body 1 be made up of the two one hinged each other connecting rods of end, on the terraced body 1 overlap joint work plane in the 1 meter scope in distance terraced body 1 top, also be installed with reeding 2, this reeding 2 adopts hard plastics to make.
Present embodiment should not be construed as qualification of the present utility model, and protection of the present utility model is as the criterion with the record of claim, and any equivalence techniques means of having done according to patent specification are replaced, and all do not break away from the protection domain of this patent.
