Claims

[Claims for Utility Model Registration] 1. A fluid transport pipe cutting machine for cutting an intermediate portion of a fluid transport pipe P, in which a machine frame 1 is provided with a receiving space V for the pipe P to be cut, and the receiving space V A cable member 3 is rotatably attached to the cable member 3 so as to cross the entrance of the receiving space V at two spaced apart locations, and the cutting blade 2 is attached to the cable member 3 at the crossing location.
This fluid transport pipe cutting machine is provided with a drive mechanism DM for rotating the cord-like body 3, which is attached so as to protrude in the direction in which the pipe P to be cut is extracted from the pipe. 2. The cable-like body 3 is installed and supported at the crossing point between a pair of hanging wheels 4 that are pivotally supported on the machine frame 1 with an interval larger than the outer diameter of the pipe P to be cut. The pair of hanging wheels 4 are arranged so that the cable body 3 is rotated by the normal rotation of the motor 11 constituting the drive mechanism DM, and by the reverse rotation of the motor 11. A one-way screw is attached to the receiving member 6 so that the receiving member 6, which is screwed onto the screw shaft attached to the machine frame 1, is screwed and moved to a fall prevention position relative to the resected portion of the pipe P to be cut. The fluid transport pipe cutting machine according to claim 1, which is attached via a clutch 14 so as to be immovable in the direction of its rotational axis.
