Description

Известны лестницы-изол торы дл  работы на проводах под напр жением .Insulator ladders are known for working on wires under voltage.

Описываема  лестница отличаетс  от известных наличием передвижной металлической рамы, котора   вл етс  защитным контуром, выравнивающим распределение электрического потенциала той части лестницы , где в каждый данный момент находитс  работающий на лестнице монтер.The described ladder differs from the known ones by the presence of a movable metal frame, which is a protective circuit, equalizing the distribution of the electric potential of that part of the ladder where at any given moment there is a fitter working on the ladder.

На фиг. 1 изображен общий вид лестницы; на фиг. 2 - часть лестницы в более крзпном масщтабе.FIG. 1 shows a general view of the stairs; in fig. 2 - part of the ladder on a more cramped scale.

Лестница-изол тор состоит из стоек /, изготовленных из электр(;изол ционного материала (налример, из дельтадревесины), металлических стержней-ступеней 2, металлизированной рабочей площадки 6.The insulator ladder consists of racks / made of electr (; insulating material (nalrimer, delta wood), metal rods-steps 2, metallized working platform 6.

На стойки / устанавливаетс  подвижна  металлическа  рама 3. соприкасающа с  с металлически1ми стержн ми-ступен ми 2. Рама .7 образует защитный контур, выравнивающий распределение потенциалов на соответствующей части лестницы при движении по ней монтера.A movable metal frame 3 is mounted on the stands / in contact with the metal rods of the steps 2. The frame 7 forms a protective circuit that equalizes the distribution of potentials on the corresponding part of the ladder when it is moved along it.

Перед пользованием лестницей рама 3 устанавливаетс  в нижней части лестницы. Затем лестница подвещиваетс  непосредственно к проводу или к другим част м электроустановки, наход щимс  под напр жением , с помощью крюков 4.Before using the ladder, the frame 3 is installed at the bottom of the ladder. The ladder is then connected directly to the wire or to other parts of the electrical installation under voltage using hooks 4.

Закрепив лестницу в требуемом положении, монтер, нажима  руко тки 5 запоров рамы 3, выводит их из зацеплени  со ступеньками и двигает раму 3 вверх, поднима сь вместе с ней но ступенькам. Подвед  раму 3 к металлизированной площадке 6, монтер отпускает руко тки 5 и поднимаетс  на площадку. В нижней части лестницы имеютс  проушины 7 дл  соединени  ее в случае необходимости со второй лестницейHaving fixed the ladder in the required position, the fitter, pressing the handle 5 of the latches of the frame 3, removes them from the engagement with the steps and moves the frame 3 upwards, lifting along with it into the steps. Lead the frame 3 to the metallized platform 6, the fitter releases the handles 5 and rises to the platform. In the lower part of the stairs there are lugs 7 for connecting it, if necessary, with the second ladder
