Title:
THREE-AXIS DISPLACEMENT MEASUREMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2014/003217
Kind Code:
A1
Abstract:
The three-axis displacement measurement apparatus according to the present invention includes: a fixed grip fixed to a hanger which supports a structure to be measured; a rotating body rotatably supported by a fixing plate; a first pipe rotatably connected to the rotating body by a first hinge connection unit; a second pipe rotatably connected to the first pipe by a second hinge connection unit; a ball joint connecting the second pipe to the fixed grip to allow 360-degree rotation; a first encoder disposed in the first hinge connection unit to measure the angle between the rotating body and the first pipe; a second encoder disposed in the second hinge connection unit to measure the angle between the first pipe and the second pipe; and a third encoder disposed in the rotating body to measure the plane rotation angle of the rotating body. According to the present invention, restrictions at an installation site can be minimized, measurement accuracy can be improved through the use of a plurality of encoders for measuring the rotation angle, and a reduction in size is made possible.
