摘要
门式起重机主要用于装卸作业,包括室外货场、散货以及料场货的装卸,其作业范围较大,可适用于多种作业场景。门式起重机整体结构为金属结构,外观形似门形框架,可以直接在地面轨道上移动,在实际使用过程中,受起重量、各系统性能、材料等多种因素影响。实践证明大车在运行过程中易出现偏斜问题,进而影响起重机正常作业。本文结合实际案例,对大跨度门式起重机运行偏斜问题,研究导致其偏斜问题的原因,并探讨了改善大跨度门式起重机运行偏斜问题的措施,为类似问题的解决提供参考。
Gantry crane is mainly used for loading and unloading operations,including loading and unloading of outdoor freight yard,bulk cargo and stock yard cargo,with a wide range of operations,which can be applied to a variety of operation scenarios.The overall structure of the gantry crane is metal structure,and its appearance is similar to the portal frame.It can move directly on the ground track.In the actual use process,it is affected by many factors such as lifting capacity,system performance,material,etc.Practice has proved that the crane is prone to deflection during operation,which will affect the normal operation of the crane.Combined with practical cases,this paper studies the causes of the deviation of the large-span gantry crane,and discusses the measures to improve the deviation of the large-span gantry crane,so as to provide reference for solving similar problems.
