Принцип работы эскалатора

13.01.2017 Раздел: Лестницы Комментарии: (110) Размер текста: A+ / A-

Наверное, каждый из на, будучи ребёнком, просто мечтал прокатится на эскалаторе. Конечно, на сегодняшний день такие устройства совсем не в диковинку в больших городах. А вот ещё лет 15 назад — прокатится на эскалаторе действительно было чем-то невообразимым.

1

Кстати, вот вам интересный факт: первый эскалатор в Лондоне был установлен в 1898 году в крупном магазине. Так вот люди настолько сильно боялись ездить на этом чуде инженерной мысли, что руководство решило поставить возле эскалатора специальных служителей. В их обязанности входило выдавать по бокалу бренди каждому, кто осмелился прокатится на дивном устройстве. Это делалось как бы с целью, чтобы люди могли «восстановится» после «страшного» поступка. А людям и нравилось.

Но, повторюсь, на сегодняшний день эскалаторы есть практически везде: в супермаркетах, торговых центрах, в метро, на вокзалах и т.д. Существует два вида эскалаторов: поэтажные и тоннельные. Первые созданы для того, чтобы поднимать людей всего лишь на один этаж. А вот тоннельные — это длинные и высокие эскалаторы, которые обычно установлены в метро. Такой вид может иметь продолжительность до нескольких десятков метров.

2

Не смотря на то, что длина и высота может быть совершенно разная, но принцип действия всегда один и тот же. Итак, если смотреть на ступеньку сбоку, то кажется, что она похожа на букву «Г». Таким образом каждая ступенька с двух сторон приделана к двум цепям. Снизу ступенька расположена на ролике — они в свою очередь двигаются по рельсам в одном направлении. Вот в общем-то и всё: цепи замыкаются в кольца, которые совершают бесконечное движение по кругу. Цепи вращаются на двух валах, которые расположены как снизу, так и сверху. Ну, а весь механизм в целом приходится в движение самым обыкновенным моторчиком, который, кстати, располагается под верхней площадкой эскалатора.

3

Кстати, хотелось бы так же сказать и о том, чего, возможно, многие и не знают. Практически все эскалаторы имеют кнопку экстренной остановки (как беговые дорожки в спортзале). Так что, если вас застала какая-то неприятная непредвиденная ситуация, вы просто можете нажать стоп-кнопку и эскалатор остановится. Обычно такие кнопки расположены на верхней и нижней площадке.

    One thing I want to discuss is that weightloss routine fast may be possible by the correct diet and exercise. An individual’s size not simply affects the look, but also the quality of life. Self-esteem, despression symptoms, health risks, in addition to physical abilities are affected in an increase in weight. It is possible to do everything right but still gain. Should this happen, a problem may be the culprit. While an excessive amount of food rather than enough workout are usually accountable, common medical ailments and popular prescriptions may greatly amplify size. Thx for your post right here.

    Le diable peut paraître burlesque comme la peur qu’il véhicule encore chez certaines personnes au XXIe siècle. En France particulièrement où l’on vit dans l’espace public avec une perception mythologique de la laïcité. La laicité qu’on déclame dans les discours politiques, celle qui penche vers une spiritualité républicaine basée, pour le dire rapidement, sur les lois, la science et les institutions. Cette laicité-là est un mythe, comme tous les mythes, elle est aveugle. C’est-à-dire qu’elle évacue toutes les formes de spiritualités qui ont explosé en France ces trente dernières années et je ne parle pas que de l’islam. Journalistiquement, c’est ce que je retiens de cette enquête, cette schizophrénie française qui m’a explosé au visage.
