Abstract
Способ извлечения поврежденного шурупов из дюбеля железобетонной шпалы заключающийся в удалении посторонних предметов из полости дюбеля шпалы, рассверливании отверстия в теле поврежденного шурупа, извлечении поврежденного шурупа из дюбеля с помощью экстрактора, отличающийся тем, что на шпалу устанавливают кондуктор, фиксируют его в полости дюбеля и за подошву железнодорожного рельса, после этого сверлят по кондуктору в теле шурупа два отверстия с эксцентриситетом "е" относительно оси шурупа, затем вставляют в полученное овальное отверстие экстрактор и извлекают поврежденный шуруп из дюбеля шпалы, при этом форма и размер рабочего наконечника экстрактора соответствуют полученному овальному отверстию. A method of extracting damaged screws from a concrete anchor dowel comprising removing foreign objects from the cavity of the sleeper dowel, drilling a hole in the body of the damaged screw, removing the damaged screw from the dowel using an extractor, characterized in that a conductor is installed on the sleeper, fixing it in the cavity of the dowel and behind the bottom of the rail, then drill two holes with an eccentricity “e” relative to the axis of the screw along the conductor in the screw body, then insert them into the oval hole Growth of the extractor and the damaged screw is removed from the dowel of the sleepers, while the shape and size of the working tip of the extractor correspond to the obtained oval hole.
