Abstract

Изобретение относитс к контрольно-измерительной технике, а именно к механическим средствам измерени глубины дефектов цилиндрических поверхностей , например глубины коррозионных дефектов поверхности магистральных трубопроводов в полевых услови х . Целью изобретени вл етс расширение номенклатуры измер емых дета- лей за счет вьтолнени корпуса устройства в виде раздвижной рамы, состо щей из четьфех изогнутых стоек 2 с пазами, установленных попарно на концах соответствующих магнитных оснований 1 и соединенных между собой шарнирами 3, и четырех т г 4, соединенных между собой шарнирами 5, установленными в пазах сухарей 7, укрепленных на стойках 2 с возможностью перемещени в них. Устройство имеет дополнительную направл ющую 11 дл перемещени каретки 12 с установленным на ней индикатором с измерительным стержнем и иглой. Шарниры 3,5 стоек 2 и т г 4 установлены в одной плоскости, параллельной плоскости направл ющих каретки 12 таким образом , чтобы измерительна плоскость иглы индикатора совпадала с плоско- стью осей шарниров. 1 з.п.ф-лы. Зил. с о (/ СThe invention relates to instrumentation engineering, in particular to mechanical means for measuring the depth of defects of cylindrical surfaces, for example, the depth of corrosion defects of the surface of main pipelines under field conditions. The aim of the invention is to expand the range of measurable parts by extending the device housing in the form of a sliding frame consisting of four curved legs with grooves installed in pairs at the ends of the respective magnetic bases 1 and connected by hinges 3 and four tons of g 4, interconnected by hinges 5 mounted in grooves of crackers 7 fixed on racks 2 with the possibility of movement therein. The device has an additional guide 11 for moving the carriage 12 with an indicator with a measuring rod and needle mounted on it. The hinges of 3.5 pillars 2 and t g 4 are installed in one plane parallel to the plane of the guide carriage 12 so that the measuring plane of the needle of the indicator coincides with the plane of the axes of the hinges. 1 hp ff.
