发表在《石油工程建设》1987年第3期上的“拖拉绳吊装受力的精确计算”一文,提出采用扒杆吊装塔器时,计算拖拉绳受力的一种新方法。这种计算方法在常规的受力分析及一般计算方法的基础上,考虑到拖拉绳的长度、直径、各拖拉绳的水平投影与主受力线的夹角、拖拉绳的预拉力和扒杆的各项几何参数等因素,按静不定系统对拖拉绳在起重吊装中的受力状况作了精确的分析。从理论上看,该计算方法合理,对正确选片用拖拉绳及锚坑的设计有重要作用。我们在天津炼油厂常减压装置改造工程的新减压塔吊装中采用了这种计算方法。实践表明,这种计算方法符合实际情况,且安全可靠,值得在塔器吊装受力计算中推中推广应用。本人曾专程赴长岭炼油厂与该文作者陈建军同志就减压塔吊装计算中某些具体问题作了 Published in the “Petroleum Engineering Construction” in 1987 third issue of “drag rope lifting accurate calculation of force,” a text, put forward the use of pole lifting tower crane, the calculation of drag rope force a new method. This calculation method based on conventional stress analysis and general calculation method, taking into account the length and diameter of the tow rope, the angle between the horizontal projection of each tow rope and the main force line, the pre-tension of the tow rope and the stripping rod Of the geometric parameters and other factors, according to statically indeterminate system on the tow rope in the crane lifting the force made a precise analysis. In theory, the calculation method is reasonable, and plays an important role in the design of the right selection of the drag rope and anchor pit. We adopted this method in the new vacuum tower hoisting of the retrofitting unit of the Tianjin refinery. Practice shows that this calculation method is in line with the actual situation, and safe and reliable, it is worth to push in the tower crane lifting force to promote the application. I made a special trip to Changling Refinery and the author, Comrade Chen Jianjun decompression tower hoisting calculation of some of the specific issues made
