A lifting, centering and adjusting mechanism of a crane beam box comprises lifting devices. Each lifting device comprises an upper platform, a lower platform and a lifting mechanism installed betweenthe upper platform and the lower platform. A centering device is arranged on each upper platform and comprises a first sliding piece and a second sliding piece, wherein a first centering baffle is arranged on the first sliding piece, and a first centering baffle is arranged on the second sliding piece. The lifting, centering and adjusting mechanism further comprises a placing platform arranged above the centering device and two supporting plates used for supporting the placing platform, wherein the bottoms of the two supporting plates are fixedly connected with the upper platforms, and the placing platform is provided with notches corresponding to the first centering baffle and the second centering baffle correspondingly, so that the first centering baffle and the second centering baffle move in the notches so as to clamp the beam box. The lifting, centering and adjusting mechanism has the functions of position lifting and automatic centering of the width center line of the beam box inthe manufacturing process, avoids manual hoisting adjustment so as to adapt to height changes and center line alignment, reduces the labor intensity, and improves the production efficiency and the safety coefficient.

    一种起重机梁盒的升降对中调节机构,包括升降装置,所述升降装置包括上平台、下平台和安装在上下平台之间的升降机构,所述上平台上设置有对中装置,所述对中装置包括第一滑动件和第二滑动件,第一滑动件上设有第一对中挡板,第二滑动件上设有第二对中挡板,还包括设置在对中装置上方的放置平台以及支撑放置平台的两支撑板,两支撑板的底部与上平台固定连接,放置平台上分别设有与第一对中挡板和第二对中挡板对应的缺口,使第一对中挡板和第二对中挡板在缺口内移动以夹紧梁盒。本发明满足梁盒在制造过程中位置的升降和宽度中心线的自动对中功能,避免了人工吊装调整以适应高度的变化和中心线的对正,降低劳动强度,提高了生产效率和安全系数。
