The invention discloses a wheel replacing and adjusting method for a large crane, belongs to the technical field of crane equipment maintenance methods, and is used for replacing and adjusting crane wheels comprising multiple groups of wheel trolleys. According to the technical scheme, the method includes the following steps that firstly, connection bolts of several groups of balance beams are dismounted simultaneously, the balance beams are jacked by the aid of a hydraulic jack, and the balance beams are transported out one by one by the aid of a transport tankette; then the manufactured balance beams and wheel groups are assembled together, the horizontal deviation of two groups of wheels on each balance trolley is adjusted to be smaller than 0.1%, then fixing bolts of the wheels are screwed and fixed, the horizontal deviation of two groups of wheels on a single balance trolley is adjusted to be out of tolerance, the horizontal deviation difference after assembly of the balance trolleys on the single side of the large crane, and fixing bolts of the balance trolleys and end beams are screwed. With the method, the wheels can be replaced quickly, the wheel mounting accuracy is improved, the horizontal combination form of the wheels is not required to be adjusted again, the wheels can reach the original mounting size, and the service life of the wheels is prolonged.
一种大型起重机车轮更换调整方法,属于起重机设备维护方法技术领域,用于对由多组车轮台车组成的起重机车轮进行更换和调整。其技术方案是:首先,对几组平衡梁的连接螺栓同时拆卸,用油压千斤顶顶升平衡梁,将平衡梁用运输小坦克上逐个运出;然后,将制作好的平衡梁与车轮组装配到一起,调整好每组平衡台车上两组车轮的水平偏差小于0.1%,然后将车轮的固定螺栓拧紧固定,调整单台平衡台车两组车轮水平偏差超差,调整大车单侧平衡台车装配后的水平偏斜差,将各平衡台车与端梁的固定螺栓拧紧。本发明可以快速进行车轮的更换,提高了车轮安装的精准度,无需重新调整车轮的水平组合形式,能够保证车轮达到原有安装尺寸,延长了车轮使用寿命。
