IPC: B62D57/024
Filed: 1994-12-14
Abstract: PURPOSE: To make a hydraulic pressure cylinder device generate a large thrust in an automatic traveling device in a pipe line. CONSTITUTION: An automatic traveling device in a pipe line is constituted to interconnect a front locking part and rear locking part through a hydraulic pressure cylinder device 33. The front locking part and rear locking part in pipe line are alternately locked on the pipe wall in the pipe line P. A cylinder device 33 is alternately expanded and contracted to act like a looper and run in the pipe line P. The cross section of a cylinder 34 of a hydraulic pressure cylinder device 33 is shaped into a notched circular from like a semicircle or meniscus and a piston 35 is also shaped to have the notched circular section mating with the section of the cylinder 34.
