Abstract:

According to the monitoring and analysis requirements of the paying off pulley during the tension paying off construction, the monitoring system of the paying off pulley is designed. The multi-parameter monitoring device based on sensor information intelligent fusion technology is adopted, and the space attitude, load and other parameter sensing monitoring units are integrated to realize the three-axis attitude and angle of the paying off pulley Real time acquisition and transmission of multi parameter data such as spatial position and load information. Combined with the setting out construction calculation method, the spatial attitude angle calculation method of the setting out pulley is proposed. The calculation results of the change of the setting out pulley load and spatial attitude angle can be obtained through the operation state of the traction rope and conductor in different stages, and compared with the monitoring data in the system to realize the real-time early warning in the construction process. Through the verification test in the transmission line project, the relative error between the measured data and the calculated data is small, which verifies the effectiveness and accuracy of the monitoring system. The setting out pulley monitoring system can provide technical guarantee for the safety of tension setting out construction process.
