The invention belongs to the technical field of mechanical inspection and maintenance of bridge cranes, and particularly relates to a bridge crane fixed pulley block rapid die changing and inspection and maintenance method. Optimization is carried out according to the fixed position structure and the inspection and maintenance mode of a fixed pulley block, and a fixed foundation base is manufactured, installed and fixed above a vehicle body according to the width size of a fixed pulley block shaft fixing pressing plate; the working environment of maintenance personnel is improved; the width of the self-made lengthened fixing pressing plate is the same as that of an original fixed pulley block shaft clamping groove, the foundation base is fixed to the position directly communicated with the upper portion of the vehicle body, two corresponding center points are selected for the new fixing pressing plate and the foundation base, two holes with the same diameter are drilled in the new fixing pressing plate and the foundation base, and fixing bolts capable of supporting stress can be conveniently installed for fixing. The operation method and the operation environment are improved; maintenance personnel can operate conveniently; the operation efficiency is improved; the labor intensity is reduced;

    本发明属于桥式起重机机械检维修技术领域,具体涉及一种桥式起重机定滑轮组快速换模及检维修方法,根据定滑轮组固定位置结构、检修方式进行优化,车体上方根据定滑轮组轴固定压板宽度尺寸,制作安装固定基础底座,改善维修人员作业环境;自制加长型固定压板,宽度与原定滑轮组轴卡槽相同宽度,直通车体上方固定基础底座,在新固定压板与基础底座选取对应的2个中心点,在新固定压板与基础底座钻直径相同的2个孔,便于安装能够支撑受力的固定螺栓进行固定。改善作业方法、作业环境,便于维修人员作业,提高作业效率,降低劳动强度,保证人员安全作业。
