The invention relates to the technical field of inclination angle fine adjustment, in particular to a simple and easy gantry member hoisting inclination angle fine adjustment method. In order to solve the problem that a portal frame is difficult to be accurately positioned at one time due to alignment welding precision of portal frame components and welding position deviation of lifting lugs, the following technical scheme is provided: the method comprises the following steps of: 1, calculating a lifting point position of a steel wire rope and the length of the used steel wire rope through lofting; secondly, a lifting lug is welded to the portal; thirdly, an adjusting device is arranged on the steel wire rope; fourthly, the two ends of a steel wire rope are connected with the lifting lugs through steel lifting rings correspondingly; fifthly, the steel wire rope is hung on a lifting hook of lifting equipment, the portal frame is lifted, and meanwhile the inclination angle of the portal frame is observed; and 6, the hoisting equipment puts down the portal frame, and the length of the steel wire rope is adjusted through the adjusting device according to the deviation of the inclination angle. The lifting operation time can be shortened, the construction cost is reduced, potential safety hazards are eliminated, and the project progress and quality are guaranteed.

    本发明涉及倾斜角微调技术领域,尤其涉及一种简单易行的门架构件吊装倾斜角微调方法。其主要针对因门架构件对口焊接精度及吊耳焊接位置偏差,导致门架难以一次准确就位的问题,提出如下技术方案:包括步骤一、通过放样计算出钢丝绳的吊点位置和所用钢丝绳的长度;步骤二、将吊耳焊接在门架上;步骤三、在钢丝绳上设置调节装置;步骤四、将钢丝绳两端分别通过钢吊环与吊耳相连接;步骤五、将吊运设备的吊钩挂住钢丝绳并将门架吊起,同时观察门架倾斜角度;步骤六、吊运设备将门架放下,根据倾斜角度的偏差并通过调节装置调整钢丝绳的长度。本发明能够缩短吊装作业时间、降低施工成本、消除安全隐患,保障工程进度与质量。
