Abstract
PURPOSE: To enable the mounting and dismounting operations to the working position of a pipe to be readily accomplished by forming the stationary frame of the device and the rotary ring supporting the stationary frame into split construction.
CONSTITUTION: The ring-form stationary frame 2 mounted to a pipe 1 is split to half frame bodies 2A, 2B which are then connected by hinges 3. The rotary ring 18 to be disposed on the surface of the stationary frame 2 is also split to half ring bodies 18A, 18B. The parting faces 4 of the stationary frame 2 and the parting faces 19 of the rotary ring 18 are alinged and are tentatively set by tentative setting mechanisms 23. The parting faces 4 of the other ends of the half frame bodies 2A, 2B are connected by means of clamping mechanisms 7. When the revolution-driving source 32 mounted to the stationary frame 2 is driven, the rotary ring 18 rotates around the pipe 1 and the welding torch 38 mounted to the rotary ring 18 gas-cuts the pipe 1. When the respective parting faces 19, 4 of the rotary ring 18 and stationary frame 2 are aligned and the clamping mechanisms 7 are opened upon ending of the cutting work, the half frame bodies 2A, 2B and half-ring bodies 18A, 18B are both force-opened, thus the device may be taken out at one time.
