Title:
INCLINOMETER INSTALLATION RECOVERY MECHANISM AND INCLINOMETER INSTALLATION RECOVERY METHOD
Document Type and Number:
Japanese Patent JP2017166280
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To easily recover a plurality of stages of inclinometer devices installed on a cutter post.SOLUTION: An inclinometer device 40 is inserted into a pipe part 30, and is connected in the axial direction Z of the pipe part 30, and is provided in a plurality of stages. A stopper 50 of the inclinometer device 40 is changeably installed in an inclinometer in a state of opening to the outside R1 in the radial direction (to the outside in the axially right-angled direction) and a state of closing to the inside R2 in the radial direction. The stopper 50 can regulate the movement in the axial direction Z of the inclinometer device 40 to te pipe part 30. When the inclinometer device 40 is moved to the extraction side (the upper side Z1) to the pipe part 30, the stopper 50 becomes a closed state, and thereby releases regulation of the movement in the axial direction Z of the inclinometer device 40 to the pipe part 30.SELECTED DRAWING: Figure 3
