The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
In the regular maintenance of power system, need to check meter to special change user, sometimes also need to change and the test energy meter.Because box of electric energy meter is fixed on the electric pole, just need to checks meter or change energy meter with insulating ladder.And some electric poles stand on the hillside, or on-site physical features is uneven, and common insulation ladder well rear ladder body is uneven, can't climb.
For solving above-mentioned purpose, the utility model embodiment provides height-adjustable insulating ladder.Fig. 1 to 3 shows a kind of structure of above-mentioned height-adjustable insulating ladder, and it comprises: insulation ladder, insulating ladder prolong leg 1 and sleeve pipe 9.Wherein:
The insulation ladder comprises insulating ladder leg 7 and the insulation footboard 4 that is arranged on the insulating ladder leg 7 at least; Insulation footboard 4 can be one-body molded with insulating ladder leg 7, also can be fixed on the insulating ladder leg 7 by pedal draw-in groove 8.
(seeing also Fig. 4 a-4b), sleeve pipe 9 comprise tube wall 91 and dividing plate 92, and dividing plate 92 forms the first compartment 401 and the second compartment 402 with tube wall 91; Also be provided with tapped through hole 93 on the tube wall 92.
Aforesaid insulating ladder leg 7 can be arranged in the first compartment 401, and is fixedly connected with tube wall 91, and insulating ladder prolongation leg 1 can move up and down in the second compartment 402.
More specifically, still see also Fig. 2, for realizing that insulating ladder leg 7 is fixedly connected with tube wall 91, can screwed hole be set at insulating ladder leg 7, then, after one end of screw 11 screws in tapped through hole 93, the screwed hole on the final and insulating ladder leg 7 screws, thereby has realized being fixedly connected with of insulating ladder leg 7 and tube wall 91.
So, on the hillside or the place of physical features injustice, the capable of regulating insulating ladder prolongs leg 1, then screw 10 is screwed in tapped through holes 93 and withstands on insulating ladder and prolong on the leg 1, makes insulating ladder prolong leg 1 fixing, makes the insulating ladder held stationary, thereby has made things convenient for climbing.
Perhaps, also insulating ladder can be prolonged leg 1 and be placed in the second compartment 402 and with tube wall 91 and be fixedly connected with, insulating ladder leg 7 then can move up and down in the first compartment 401.Screw is screwed in tapped through hole 93 withstand on the insulating ladder leg 7, make it fixing, can make the insulating ladder held stationary equally, thereby made things convenient for climbing.
In like manner, for realizing that insulating ladder prolongs leg 1 and is fixedly connected with tube wall 91, insulating ladder prolongs on the leg also can arrange screwed hole, and therefore not to repeat here.
In addition, screw screws on that end of tapped through hole 93 also can be equipped with nut, and the size of nut is greater than the size of tapped through hole 93, can prevent that like this screw from deviating from tapped through hole 93.
When changing and test energy meter, need to use tester.In order to lay tester, still see also Fig. 1-3, in other embodiment of the utility model, also can comprise end face 12 on the above-mentioned insulation ladder.
For reducing area occupied, above-mentioned end face 12 can comprise first fold lamination 13 and the second folded sheet 14, and first fold lamination 13 is connected by folding axis of rotation 5 with the second folded sheet 14.By folding axis of rotation 5, can be with the insulating ladder folds flat.
Further, first fold lamination 13 and the second folded sheet 14 all can comprise two flat boards, and, these two collapsible placements of flat board (referring to Fig. 3), thus area occupied further reduced.
For guaranteeing that insulating ladder does not in use slip.In other embodiment of the utility model, at least one cover that above-mentioned insulating ladder leg 7 and insulating ladder prolong in the leg 1 has Anti-slip cover 3.Anti-slip cover can be specially the rubber antiskid cover, its with decorative pattern can be set on the one side that contacts, to increase friction.
Each embodiment adopts the mode of going forward one by one to describe in this manual, and what each embodiment stressed is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, in other embodiments realization.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
