水下金刚石绳锯机是近年发展起来的一种清洁环保的水下作业机械。介绍了其构成及工作原理。分析了单个串珠切割过程中的受力,针对管道的切割,建立了其力学模型,通过对模型的分析,获得了绳锯切割过程中串珠所受压力的计算公式。为使串珠绳锯在切割过程中能够实现一定的周向自转,需预先在串珠绳锯上施加一定的扭矩,得出了相应的计算关系式。搭建了水下绳锯机试验系统,对串珠绳锯切割过程中的特性进行了试验研究。结果表明:试验结果比较符合相应的理论,该结果为水下绳锯机切割过程参数的进一步合理优化选择提供了依据。

Underwater diamond wire sawing machine is a kind of clean and environmentally friendly machinery that is developed in recent years. Its structure and working principle are introduced. The force of single bead cutting process was analyzed,aiming at the pipe cutting,the mechanical model was established. Through the analysis of the model,the calculation formula of the pressure on the bead in the process of wire saw cutting was obtained. In order to make the bead rope saw in the cutting process achieve a certain degree of circumferential rotation,a certain torque might be applied to the bead rope saw in advance,and the corresponding calculation formula was obtained. The underwater wire sawing machine test system was set up,the characteristics of bead wire saw in cutting process were experimentally studied. The results show that the experimental results are in good agreement with the corresponding theory,which provide a basis for further rational optimization of cutting parameters of underwater wire sawing machine.
