用于水下作业的锯绳张力检测系统

Tension Measure System of Saw Wire for Underwater Working

为了使金刚石串珠绳锯能够完成海底输油复合管道的切割作业,通过锯绳张力的检测可以监控切割状态,保证切削与进给运动处于协调状态。文中分析了锯绳切割时的受力状态,采用力合成法设计了张力传感器的机械结构,提出了上、下单片机通讯的水下锯绳张力的检测方案;设计了检测张力传感器,介绍了受力检测工作原理,对传感器进行了标定和精度分析;进行了锯绳水下切割管道张力检测试验,结果验证了锯绳水下张力检测方法的可行性、可靠性。

Using diamond saw wire can incise the seabed oil compound pipes, and its state being incised can be monitored by measuring the tension of diamond saw wire, so, it makes the cutting and advancing velocities under the condition of harmony. The tension of saw wire was analyzed at its working condition, the mechanism of the tension sensor was designed by the method of corn- position of forces, and the measuring method about tension of saw wire based on up-down single chip was put for- ward. The tension sensor was designed and its detection principle was introduced. Its calibration and accuracy were carried out, The test of examining tension underwater was done and the result validated its feasibility and reliability.
