Pipe inside lining material cutting device

Abstract

Abstract PURPOSE:To unnecessitate computer control by providing a reamer provided with a drill and a bearing guide at a pipe inside lining material cutting device for cutting the inside lining material of a sewer main pipe along a fitting pipe opening part and operating this cutting device by remote control. CONSTITUTION:The title device 39 is provided with a longitudinally driving cylinder 46 for driving a main cylinder 47, the longitudinally movable main cylinder 47, and a rotating cylinder 48 for rotating a main cylinder rod 47a through a gear mechanism 50 disposed on a cylinder supporting base 44 driving on a rail 40. In addition, elevating cylinders 52, 53 are provided at the tip of the main cylinder rod 47a through an elevating cylinder guide 51, as well as elevating cylinders 56, 57 are provided through elevating holders 54, 55. A drill 64 and a reamer 65 are used stepwise for the cutting of the inside lining material in a main pipe, and when the specified force distribution is applied to the longitudinal movement and the lateral movement, by rotation, of the rod 47a, the reamer 65 is guided by a guide 65b so as to cut the inside lining material into hold shape.
