Abstract

Изобретение относитс  к оснащению стволов шахт и рудников. Целью изобретени   вл етс  обеспечение использовани  обтекател  в стволах разных диаметров в плане. Обтекатель рассрела 1 состоит из корпуса 2, выполненного из центральной и торцовых частей корпусов. Торцовые части установлены на центральной внахлестку, изготовлены с возможностью радиального раздвижени . Торцовые части выполнены с возможностью огибани  кра ми пазов 5 кромки 6 центральной части. Узлы креплени  7 корпуса изготовлены в виде вогнутых к расстрелу 1 пластин и укреплены с обеспечением перемещени  торцовых частей к стенкам ствола с помощью ручек 9. 2 ил.The invention relates to equipping shafts of mines and mines. The aim of the invention is to ensure the use of a wing in the trunks of different diameters in the plan. The fairing is rassrela 1 consists of a body 2 made of the central and end parts of the body. The front parts are mounted on the central overlap, made with the possibility of radial expansion. The end parts are made with the possibility of bending around the edges of the grooves 5 and the edges 6 of the central part. The mountings 7 of the body are made in the form of plates concave for shooting 1 and are reinforced so that the end parts move to the walls of the barrel with the help of handles 9. 2 Il.
