Description
(54) ВНУТРЕННИЙ ЦЕНТРАТОР ДЛЯ СБОРКИ ПОД СВАРКУ ТРУБ(54) INNER CENTER FOR ASSEMBLY UNDER PIPE WELDING
Изобретение относитс к области сварки, в частности к устройствам дл центрировани труб при сборке под сварку, и может быть применено при монтаже заводских и технологических трубопроводов, в энергетической и других отрасл х промь нленности ,The invention relates to the field of welding, in particular to devices for centering pipes during assembly for welding, and can be applied during installation of factory and process pipelines, in power and other industrial circuits,
Известен внутренний центратор дл сборки под сварку труб, наиболее близкий к предлагаемому изобретению по технической сукц-юсти, содержащий центрирующий корпус с приводньзми роликами и механизм его торможени 1J.An internal centralizer for assembling for welding of pipes is known, which is closest to the proposed invention in accordance with the technical process of welding, containing a centering housing with driving rollers and a braking mechanism 1J.
Механизм торможени в известном центраторе содержит тормозной рычаг и трос с руко ткой и св зан с корпусом. Однако ручной привод механизма торможени создает трудности в эксплуатации, поскольку требует больших трудозатрат при управлении центратором ,а также не обеспечивает точности установки его на свариваемый стык.The braking mechanism in the known centralizer contains a brake lever and a cable with a handle and is connected to the body. However, the manual drive of the braking mechanism creates difficulties in operation, since it requires great effort in managing the centralizer and also does not ensure the accuracy of its installation on the welded joint.
Целью изобретени вл етс обеспечение возможности автоматической фиксации центратора на стыке труб.The aim of the invention is to provide the possibility of automatic fixation of the centralizer at the junction of the pipes.
Дл этого .в предлагаемом центраторе механизм торможени выполнен в виде двуплечего рычага, закрепленного на центрирующем корпусе, т ги, расположенной перпен,цнкул рно продольной Оси трубы, эксцентриковых роликов и подпружиненного относительно корпуса и рычага копирного ролика, причем эксцентриковые ролики установлены с возможностью вращени на т ге, шарнирно св занной с одним плечом рычага, а копирный ролик кинематически св зан с другим плечом рычага.For this. In the proposed centralizer, the braking mechanism is made in the form of a two-arm lever mounted on the centering case, the thrust located perpendicular, the longitudinal axis of the pipe, eccentric rollers and spring-loaded relative to the body and the copier roller lever, and This is a hinge that is pivotally connected to one arm of the lever, and a copy roller is kinematically connected to the other shoulder of the lever.
На чертеже представлена схема предлагаемого центратора.The drawing shows the scheme of the proposed centralizer.
Внутренний центратор состоит из цантрпругащего корпуса 1 с приводныи роликами (на чертеже не показаны ) и механизма торможени , который содержит двуплечий рычаг 2, закрепленный на корпусе 1, на одном конце которого установлен копирньй ролик 3 с пружинами 4 сжати а другой конец двуплечего рычага 2 шарнирно соединен с т гой 5. На концах т ги закреплены с возможностью поворота эксцентриковые ролики б и 7,The inner centralizer consists of a treadmill housing 1 with driven rollers (not shown) and a braking mechanism that contains a double-arm lever 2 mounted on housing 1, at one end of which is mounted a roller 3 with springs 4 pressed and the other end of two shoulders 2 pivoted connected to step 5. At the ends of the rod, eccentric rollers 6 and 7 are fixed with the possibility of rotation,
