流体輸送管穿孔装置。[Claims for Utility Model Registration] 1. A connection case 2 that is attached to hold the fluid transport main pipe 1 and is formed with a connection port 6 for the fluid transport branch pipe 5, and the fluid transport of the connection case 2. Work case 3 that can be connected to the communication port H in the direction perpendicular to the axis of the main pipe 1
and a rotary cutting device that is installed in the work case 3 and cuts off the peripheral wall portion 1a of the fluid transport main pipe 1 as it is inserted and moved into the connection case 2 through the communication port H. In the fluid transport pipe perforation device, the rotary cutting device includes a cylindrical cutter 4 that is rotationally driven around an axis X perpendicular to the axis of the fluid transport main pipe 1, and a rotation center of the cylindrical cutter 4. and a rod-shaped shaft member 4A located in the connecting case 2, and is fitted onto the shaft member 4A as the cylindrical cutter 4 is inserted into the connection case 2 to guide the insertion movement of the cylindrical cutter 4. A cylindrical guide member 8 is provided, and the tip position of the shaft member 4A and the position of the cylindrical guide member 8 in the cutter insertion and movement direction are adjusted such that the tip of the cylindrical cutter 4 is located at the fluid transport book. The guide members 8 are positioned so that they are fitted together before contacting the outer periphery of the tube 1, and the guide members 8 are connected to the spherical bearing portion 9.
A fluid transport pipe perforation device that is installed so that its direction can be changed freely through the fluid transport pipe. 2. A holding mechanism for holding the circumferential wall 1a of the cut fluid transport main pipe 1 with the inner circumferential surface of the cylindrical cutter 4 by the guide member 8 engaging with the shaft member 4A. The fluid transport pipe perforation device according to claim 1, which is attached to the connection case 2 via a member 7. 3. The fluid transport pipe perforation device according to claim 2, wherein the holding member 7 is attached to the connection case 2 in a detachable manner from the outside.
