我厂在建造100吨海吊的过程中,结合其四连杆的结构特点,总结了“长度测量法”的不利条件,提出了采用经纬仪和“坐标测量法”的新工艺,节省了劳动量,提高了精度,从而保证了100吨海吊的四连杆:臂杆、拉杆和象鼻梁等大型金属构件的找正和装配质量,提高工效三倍以上。海吊四连杆或其他大型金属构件的找正加工、装配质量,以及能否顺利组装,主要取决于各构件联接铰点的平行度。因此各铰孔平行度的技术要求,是大型金属构件装配质量的主要技术指标。 In the process of constructing 100-ton crane, combining with the structural characteristics of its four-bar linkage, the disadvantages of “length measurement method” were summarized, and the new technology using theodolite and “coordinate measuring method” was put forward to save labor , To improve the accuracy, thus ensuring the four-link 100-ton crane: the alignment and assembly quality of large metal components such as the arm, the rod and the nose bridge, and improve work efficiency more than three times. Sea crane four connecting rod or other large metal components of the processing, assembly quality, and the ability to successfully assembled, mainly depends on the joint hinge point parallelism. Therefore, the technical requirements of the parallelism of reaming holes, is the main technical indicators of the assembly quality of large metal components.
