Claims

[Claims for Utility Model Registration] 1. A main body 10 that moves within the conduit 4, and the main body 10
a pair of lift legs 13, 14, each of which is provided on both sides of the lift leg 13, 14, and whose tip portions swing up and down via a link mechanism by a driving means 17;
A wheel 15 is removably attached to the tip of the main body 1 directly or via attachments 19 and 20, and the distance in the width direction varies depending on the method of attachment.
an outrigger set 22 that is removably attached to the upper part of the main body 10 and can change the height of protrusion from the upper surface of the main body 10 by combining the outriggers 22;
a stroke rotary actuator incorporated in the actuator, and a drilling head 30 that is detachably attached to the actuator's operating shaft 11 directly or via attachment plates 31 and 32 that change the attachment position in the vertical direction; a spindle 34 which is rotatably driven by a rotating shaft in the radial direction of the pipe line 4 with respect to the drilling head 30 and is provided so as to be movable back and forth in the axial direction;
Directly or with a spacer 3 at the tip of the spindle 34
