The invention discloses a revolving support device for lifting equipment. The revolving support device comprises a revolving support body, wherein the revolving support body comprises a revolving support outer ring and a revolving support inner ring; the outside of the revolving support inner ring is rotationally sleeved with the revolving support outer ring; the revolving support body is arrangedon an upper part of a lower platform; and a lower platform sleeve is arranged on an upper part of the lower platform. When a part of teeth of a gear part of the revolving support fail due to wear, the revolving support outer ring is rotated by 90 degrees through a paired pinion, so that the unused gear part is in a working area. After the angle is adjusted properly, a positioning pin is reinserted into the lower platform and the revolving support outer ring, so that the unused gear part is in the working area, and the revolving support for the lifting equipment can continue to work. Through the adoption of the revolving support device, the utilization rate of the revolving support can be improved to the maximum extent. In addition, the revolving support of an automobile crane is not disassembled, so that the disassembly cost is lowered.

    本发明公开了一种起重设备用回转支承装置,包括回转支承本体,回转支承本体包含有回转支承外圈和回转支承内圈,回转支承外圈转动套装在回转支承内圈的外部,所述回转支承本体安装在下平台的上部,下平台的上部安装有下平台套筒。当该回转支承的齿轮部分有部分齿磨损失效时,通过配对小齿轮将回转支承外圈旋转角90°,使之前未使用过的齿轮部分处于工作区域。角度调整好之后,将定位销重新插入下平台与回转支承外圈的内部,这样可以使之前未使用过的齿轮部位处于工作区域,起重设备用回转支承可以继续进行工作。这种装置尽最大可能的提高了回转支承的利用率,而且汽车起重机回转支承未拆卸,从而减少了拆卸成本。
