Embodiment Construction
[0014] refer to figure 1 , a pipeline path measuring device of the present invention comprises a fuselage and a wheel set arranged on the fuselage, the wheel set includes at least three righting brackets arranged radially around the fuselage and rollers 2 arranged on the righting brackets, The front end of the fuselage is provided with a traction head 1 for connecting a transmission cable 6. The traction head 1 is equipped with an attitude sensor and a stroke encoder, and the attitude sensor and the stroke encoder transmit the detected data to the upper position through the transmission cable 6. Machine, the fuselage is made of stainless steel pipe body, which reduces the quality of the whole machine and makes the structure stronger. The attitude sensor used is a high-performance three-dimensional motion attitude measurement system based on MEMS technology. It includes three-axis gyroscopes, three-axis accelerometers, three-axis electronic compass and other motion sensors, and...
