Abstract

Машина для контактной стыковой сварки труб большого диаметра, содержащая наружный сварочный трансформатор с токоподводами, внутренний манипулятор, выполненный в виде подвижного и неподвижного относительно корпуса центрирующих блоков с установленными на них гидроцилиндрами зажатия свариваемых труб и осевого перемещения их в процессе сварки, связанными с гидравлической системой питания и управления этими гидроцилиндрами, а также штангу для перемещения манипулятора относительно стыков труб, отличающаяся тем, что, с целью повышения ремонтоспособности машины, штанга жестко соединена с корпусом манипулятора и выполнена полой с расположенной внутри нее гидравлической системой питания и управления гидроцилиндрами зажатия и осевого перемещения труб в процессе сварки, гидроцилиндры осевого перемещения закреплены на корпусе подвижного центрирующего блока между его гидроцилиндрами зажатия, при этом штоки указанных гидроцилиндров жестко связаны с корпусом манипулятора.A machine for contact butt welding of large-diameter pipes containing an external welding transformer with current leads, an internal manipulator made in the form of centering blocks movable and stationary relative to the body with hydraulic cylinders clamped on them and their axial movement during welding associated with the hydraulic power system and control of these hydraulic cylinders, as well as a rod for moving the manipulator relative to the pipe joints, characterized in that, in order to increase re Onto the machine, the rod is rigidly connected to the manipulator body and is made hollow with a hydraulic power supply system located inside it and controlling the hydraulic cylinders for clamping and axial movement of pipes during welding, the hydraulic cylinders for axial movement are fixed on the body of the movable centering block between its clamping hydraulic cylinders, and rigidly connected to the body of the manipulator.
