The application discloses a small
shield machine pose detection device and method in curved
pipe curtain construction, a one-dimensional
workbench is initially at the highest point of a guide rail through the gravity of a heavy hammer, the guide rail is vertically installed on a jacking mechanism rack, and a long
grating displacement sensor measures the
vertical displacement coordinates of the one-dimensional
workbench in real time. In the construction process, a cross joint measurement module passes through a
pipe joint, a convex
flange one end is connected with a concave
flange at the
tail of the
shield machine, the concave
flange one end is connected with a convex flange at the bottom of the one-dimensional
workbench, two circular
grating angle sensors and a circular
grating reading head are arranged on the cross joint, the rotation angle measurement of two mutually perpendicular axes of the cross joint is realized, a
Bluetooth wireless transmission module reads the rotation angles of each joint at the same time, and the rotation angles are transmitted to a computer, the computer collects each data every moment, the position coordinates of the top end of the
shield machine relative to a reference coordinate
system are obtained through calculation, and the
pose of the shield
machine is detected in real time.
