Suspension arm turning-over method
The invention provides a lazy arm turning method which comprises the following steps: firstly, horizontally lifting a lazy arm, lifting the lazy arm away from a supporting surface, then loosening a steel wire rope group by a third lifting device, enabling a second side of the lazy arm to rotate relative to a first side due to the same horizontal height of a first lifting point and a second lifting point, turning the lazy arm for the first time, and then moving the third lifting device; the third lifting device is connected with the fourth lifting point, so that interference caused by connection of the steel wire rope group and the second side of the lifting arm from the upper part of the lifting arm is avoided, and after the moved third lifting device is connected with the fourth lifting point, the third lifting device tightens the steel wire rope group and drives the second side of the lifting arm to continuously rotate relative to the first side, and the lifting arm is turned over again; the lifting arm is overturned twice, so that the lifting arm is overturned by 180 degrees relative to the initial state, and different positions of the lifting arm can be conveniently welded and machined.
本发明提供一种吊臂翻身方法，先将吊臂水平吊起，将吊臂吊离支撑面，然后第三起吊装置松开钢丝绳组，由于第一吊点和第二吊点的水平高度相同，使得吊臂的第二侧相对第一侧转动，吊臂进行第一次翻转，然后移动第三起吊装置，第三起吊装置与第四吊点连接，这样避免钢丝绳组从吊臂上方与吊臂第二侧连接造成干涉，通过移动后的第三起吊装置与第四吊点连接后，第三起吊装置收紧钢丝绳绳组，驱动吊臂的第二侧相对第一侧继续转动，吊臂再次进行翻转；通过对吊臂进行两次翻转，实现吊臂相对起始状态翻转了180°，便于对吊臂的不同位置进行焊接加工。
