1.制作组装工装的原因组装桥式起重机主梁与端梁时,传统的组装工艺是使用起重机将端梁吊装在主梁上进行组装。具体方法是先采用垫铁将主梁垫至一定高度,再使用起重机将端梁吊起,调整到与主梁组装位置,达到图纸要求尺寸。采用此种组装工艺存在3项缺点:一是需长时间占用1台起重机,影响其他工序使用;二是起吊端梁进行位置调整,工作效率低;三是吊装过程中端梁会产生摇摆,不但影响主梁与端梁
1. The reason for making assembly tool When assembling the main girder and end beam of overhead traveling crane, the traditional assembly process is to use the crane to hoist the end beam on the main beam for assembly. The specific method is to first use the horn pad to a certain height of the main beam, and then use the crane to lift the end beam, adjusted to the position with the main beam assembly to achieve the required size drawings. There are three disadvantages of using this assembly process: one is to take a long time to take up a crane, affecting the use of other processes; the second is to lift the end beam position adjustment, low efficiency; the third is lifting the end beam will swing, not only Affect the main beam and the end beam
