管用穿孔装置。[Claims for Utility Model Registration] A gate valve 6 which can be communicatively connected to a connection case 3 attached to a fluid transport pipe 1 in a manner to form a sealed space 2 between the fluid transport pipe 1 and the outer peripheral surface of the fluid transport pipe 1.
A working case 6 is provided, and when the working case 6 is in communication with the connecting case 3, it rotates around an axis X located outside the fluid transport pipe 1 through the connecting ports 6b and 3a. A cylindrical cutter 7, which can cut the fluid transport pipe portion 1a located on the insertion movement path by inserting and moving into the connection case 3 along the axis X, is installed in the work case 6, and The cutter 7 can be fixedly connected to the case 3 in a state where it can be fixed and released from the outside of the case, and when the cutter 7 is inserted and moved to the cutting end position in the state of being fixedly connected to the connection case 3, the guide 7A is automatically connected to the shaft core of the cutter 7. Along with connecting,
A pipe punching device is provided with a detachment prevention tool 8 that comes into contact with a cut fluid transport pipe section 1a to prevent the fluid transport pipe section 1a from leaving the cutter 7. A pipe punching device in which a contact portion 8B that contacts the transport pipe portion 1a is configured to be rotatable around the axis X. The pipe punching device according to claim 1, wherein the contact portion 8B has an annular shape extending around the axis X.
