Abstract
Изобретение относитс к сварке и может быть использовано при сварке наружных кольцевых швов магистральных трубопроводов, имеющих гибы. Цель - обеспечение возможноаи извлечени устройства из длинномерных труб с гибами после их сварки. Устройаво содержит неподвижный корпус 1, основные 2 и дополнительные рычаги 3 и 4, шар- мирно зафепленные соответственно на корпусе 1 и на секторах 5, образу четыре параллелограмма На корпусе 1 подвижно размещена т га 6, подпружиненна к нему пружиной 7, а дополнительные рычаги 3, 4 параллелограммов кинематически св заны с т гой б через шарнирно залепленные на ней планки 8. В двух диаметрально противоположных параллелограммах шарниры 9 креплени планок 8 к дополнительному рычагу 3 размещены между шарнирами креплени этого дополнительного рычага к корпусу 1 и к сектору 5. В дополнительных рычагах 4 шарнир 10 размещем за шарниром креплени к корпусу 1 рычага 4. На корпусе 1 закреплен подпружиненный пружиной 11 фиксатор 12, взаимодействующий одним концом с подвижной т гой б, а на другом его конце закреплена гибка св зь 13 ручного привода. В корпусе 1 выполнен канал 14 подачи защитного газа, имеющий радиальные сверлени 15, соединенные с секторами 5 гибкими элементами 16. На наружной образующей секторов 5 выполнена перфораци . Каждый сектор 5 шабжен парой подпружиненных роликов 17, контактирующих в рабочем положении с внутренней поверхностью свариваемых труб 18 и 19. Компактноаь устройава повышаетс за счет сведени секторов через один в разные стороны по длине корпуса, а компактное расположение элементов устройства в сложенном виде обеспечивает возможность его извлечени из труб поапе сварки, бил.,FIELD: welding. SUBSTANCE: invention can be used in welding of outer circumferential seams of trunk pipelines having bends. The goal is to ensure that the device can be removed from long pipes with bends after welding. The device contains a fixed housing 1, the main 2 and additional levers 3 and 4, spherically locked on the housing 1 and sectors 5, respectively, in the form of four parallelograms. On the housing 1 is movably placed t 6, spring-loaded to it by spring 7, and additional levers 3 , 4 parallelograms are kinematically connected with the throat through the strips pivotally sealed on it 8. In two diametrically opposite parallelograms, the hinges 9 of the fastening of the slats 8 to the additional lever 3 are located between the hinges of the fastening of this additional the lever to the housing 1 and to the sector 5. In the additional levers 4, the hinge 10 is placed behind the hinge of fastening to the housing 1 of the lever 4. On the housing 1 is fixed a spring-loaded spring 11 latch 12, which interacts at one end with a movable rod b, and is fixed at its other end flexible coupling 13 of a manual drive. A protective gas supply channel 14 is made in the housing 1, having radial drillings 15 connected to sectors 5 by flexible elements 16. Perforation is performed on the outer generatrix of sectors 5. Each sector 5 is shabby by a pair of spring-loaded rollers 17 in contact with the inner surface of the welded pipes 18 and 19. The compact device is increased by reducing sectors through one in different directions along the length of the housing, and the compact arrangement of the elements of the device when folded allows for its removal from pipes for welding, beat.,
