кромка резца 4 кас аетс полки сегмента 2. Замок 3 скрепл ет сегменты 1 и 2. В данной крепи зтмок 3 можег быть клиновой, в виде гаечного.the edge of the cutter 4 touches the flange of the segment 2. The lock 3 fastens the segments 1 and 2. In this lining, the light 3 can be a wedge, in the form of a wrench.
Крепь работает следующим образом.The support works as follows.
При достижении определенной величины горного давлени сегменты 1 и 2 начинают перемещатьс один относительно другого.. Резец 4, перемеща сь вместе с сегментом 1 относительно сегмента 2, срезает стружку с последнего. Поскольку резец 4 срезает металл по всей длине верхн ка 2 в пределах податливости крепи, это позвол ет обеспечить более плавный характер работы крепи, исключает проскальзывание.When a certain value of rock pressure is reached, segments 1 and 2 begin to move relative to each other. Cutter 4, moving together with segment 1 relative to segment 2, cuts off chips from the latter. Since the cutter 4 cuts off the metal along the entire length of the top 2 within the limits of flexibility of the support, this allows for a smoother nature of the work of the support, eliminates slippage.
Демонтаж крепи производитс в такой последовательности.The dismantling of the support is carried out in such a sequence.
Разбирают замок 3, рассоединшот стойку 1 и верхн к 2 и снимают их.Disassemble lock 3, disconnect strut 1 and up to 2 and remove them.
После демонтажа крепь можно использовать повторно.After dismantling the support can be reused.
Предлагаема крепь проста, технологична , трудоемкость ее изготовлени невелика . Конструкци крепи позвол ет мо тировать и демонтировать ее с наименьшими затратами. Крепь повышает надежность работы узлов податливости, поаво-The proposed support is simple, technological, the complexity of its manufacture is small. The support structure allows you to motivate and dismantle it at the lowest cost. The support increases the reliability of the operation of the nodes of compliance,
