BORING MACHINE
To provide a boring machine in which positional deviation can be prevented with a simple configuration and a punching blade can surely be positioned.SOLUTION: A boring machine 1A includes: a punching blade 10; a motor which rotates the punching blade 10; a cable which connects the motor to the punching blade 10; and a fixing member 30 which is provided on a tip side of the cable and fixes the cable 15 and the punching blade 10 at a prescribed position in a pipe. The boring machine 1A forms a hole for communicating a regenerated pipe buried in the ground with a branch pipe B mounted in the regenerated pipe M. An insertion hole through which the cable 15 and the punching blade 10 are passed is formed in the fixing member 30. One or more sections 33a to be locked viewed from an axial line L direction of the insertion hole are formed on an inner peripheral surface 31a of the fixing member 30. A positioning member 20 which is movable to the tip side while pressing the punching blade 10 and has a locking section 23 locking the section 33a to be locked at a prescribed position in the insertion hole is provided on a rear end side of the punching blade 10. The fixing member 30 and the positioning member 20 advance the punching blade 10 in a stepwise manner toward the regenerated pipe M.SELECTED DRAWING: Figure 3
【課題】簡易な構成にて位置ズレを防ぎ、確実に穿孔刃の位置決めができる削孔機のを提供【解決手段】本発明の削孔機１Ａは、穿孔刃１０と、穿孔刃１０を回転させるモータと、モータと穿孔刃１０とを連結するケーブルと、ケーブルの先端側に設けられ、ケーブル１５及び穿孔刃１０を管内の所定の位置に固定する固定部材３０とを備え、地中に埋設された更生管Ｍと更生管Ｍに取り付けられた枝管Ｂとを連通させる孔を形成する削孔機１Ａで、固定部材３０にケーブル１５及び穿孔刃１０を通す挿通孔が形成され、固定部材３０の内周面３１ａに挿通孔の軸線Ｌ方向に見て被係止部３３ａが一つ以上形成され、穿孔刃１０の後端側には、穿孔刃１０を押しつつ先端側に移動可能であり、挿通孔内の所定の位置で被係止部３３ａに係止させる係止部２３を備えた位置決め部材２０が設けられ、固定部材３０と位置決め部材２０とが更生管Ｍに向かって穿孔刃１０を段階的に前進させる。【選択図】図３
