The invention discloses a stepped hoisting system and hoisting method for a heavy bridge crane. The stepped hoisting system comprises an advancing chassis, a retractable slope, stepped positioning structures and stepped lifting structures. The advancing chassis comprises driving advancing wheels and a slope containing cabin. The driving advancing wheels are arranged on the two sides of the advancing chassis in the equipment lifting direction. The plurality of stepped positioning structures are in one-to-one correspondence with the plurality of stepped lifting structures. The stepped lifting structures are movably connected to the top of the advancing chassis through the stepped positioning structures, and the placing distances of the stepped lifting structures can be adjusted through the stepped positioning structures. The stepped lifting structures can lift components such as a crane end beam and the like to an installation position in a staged mode. The stepped lifting structures canlift the components such as the crane end beam and the like to the installation position in a staged mode, so that the requirement on the operation space is low. Sliding friction is changed into rolling friction when the equipment components pass through an inclined guide plate through rolling balls, and the conveying difficulty is reduced.
本发明公开了一种用于重型桥式起重机的阶梯式吊装系统及吊装方法,包括行进底盘、收放斜坡、阶梯调位结构和阶梯抬递结构;所述行进底盘包括驱动行进轮和斜坡收容舱;所述驱动行进轮沿设备抬递方向设于行进底盘两侧;若干所述阶梯调位结构与若干所述阶梯抬递结构一一对应;所述阶梯抬递结构通过阶梯调位结构可移动式连接于行进底盘顶部,所述阶梯抬递结构可通过阶梯调位结构调整摆放间距;所述阶梯抬递结构可以将起重机端梁等部件分阶段式起吊至安装位置;通过阶梯抬递结构可以将起重机端梁等部件分阶段式起吊至安装位置,对作业空间需求低;通过滚珠将设备部件通过斜导板时由滑动摩擦变为滚动摩擦,降低运送难度。
