The invention discloses a pin lifting tool special for a crane. The pin lifting tool comprises a top frame, a hydraulic cylinder arranged at one end of the top frame and a top head fixedly connected to the end of a rod body of the hydraulic cylinder. The top frame comprises a square bottom rod, a vertical rod fixedly connected above one end of the square bottom rod and a top plate arranged on the square bottom rod, the top plate is arc-shaped, the end, away from the vertical rod, of the square bottom rod is a slope, one end of the top plate is fixedly connected with the upper side, away from the vertical rod, of the square bottom rod, and the other end of the top plate is fixedly connected to the upper end of the vertical rod, so that the whole top frame is of a triangular structure. The hydraulic cylinder is connected with a small hydraulic station; a groove matched with the pin shaft is formed in the side, away from the hydraulic cylinder, of the top head; and a lifting device is arranged on the hydraulic cylinder. The hydraulic jacking device can be well jacked between the two arm supports with the included angle being an acute angle, the hydraulic cylinder stretches out, the jacking head can jack out the jacking pin at the other end, operation is easy and convenient, the working efficiency is greatly improved, the labor intensity is reduced, and the working safety is improved.
本发明公开了一种起重机专用顶销工具:包括顶架、设于顶架一端的液压缸、固连在液压缸的杆体端部的顶头;顶架包括方形底杆、固连在方形底杆一端上方的竖杆、设于方形底杆上的顶板,顶板呈弧形,方形底杆的远离竖杆端呈斜坡,顶板一端与方形底杆的远离竖杆端的上侧固连,顶板另一端固连在竖杆的上端,从而使顶架整体呈三角形结构,液压缸连接有小型液压站;顶头的远离液压缸测设有与销轴相配适的凹槽;液压缸上设有提升装置。本发明可以很好地顶在夹角为锐角的两个臂架之间,通过液压缸伸出,顶头可以将另一端的顶销顶出,操作简单方便,大大提高了作业效率、降低劳动了劳动强度,提高作业安全性。
