The invention relates to the related field of slewing bearing replacement equipment, in particular to a crane slewing bearing replacement device which is characterized in that two mounting seats are arranged, jacking hydraulic cylinders are arranged on the two sides of the tops of the mounting seats, and when a slewing bearing of a crane needs to be replaced, the jacking hydraulic cylinders jack a track of the slewing bearing firstly, and the jacking hydraulic cylinders are used for jacking the track of the slewing bearing; then an adjusting plate, an electric rotating disc, an electric telescopic frame and an electric telescopic rod are adjusted, a second motor and a bolt sleeve are moved to the position of a fixing bolt of the track needing to be disassembled, the fixing bolt is disassembled through the bolt sleeve, then all pressing plate bolts and clamping plates of the track are disassembled, and the upper track and the lower track can be disassembled together with the wheel set; when damaged parts are replaced, the damaged parts are reversely installed, so that the slewing bearing is replaced and installed without being limited by operation occasions of the crane and under the condition that the parts of the crane are not disassembled, large hoisting equipment and a large amount of manpower are prevented from being adopted for assisting and matching, and the cost is greatly saved.

    本发明涉及回转支承更换设备相关领域,具体为一种起重机回转支承更换装置,本发明通过设置两个安装座,且在安装座顶部两侧设置有顶升液压缸,在对需要对起重机的回转支撑进行更换时,首先由顶升液压缸对回转支撑的轨道顶起,随后调整调节板、电动转盘、电动伸缩架和电动伸缩杆,将第二电机和螺栓套移动到需要拆卸轨道的固定螺栓处,由螺栓套对固定螺栓进行拆卸,然后拆除该段轨道的所有压板螺栓及卡板,上下轨道连同车轮组即可一同拆卸,当更换损坏的零部件,再反向安装回去即可,从而实现了不受起重机作业场合的限制、在不拆卸起重机部件的情况下更换安装回转支承,避免了采用大型的吊装设备和大量的人力辅助配合,大大节约了成本。
