The invention belongs to the technical field of crane equipment, and particularly relates to a reinforcing device for a cantilever crane stand column. The reinforcing device comprises a stand column,and a transverse column is arranged at the vertical position above the stand column; a fixing base is arranged on one side of the stand column, and a bearing rod is arranged at the connection positionbetween the stand column and the transverse column; and a groove is formed in the transverse column. A first screw is arranged in the groove in a penetrating mode, and an annular plate is arranged onthe outer surface of the middle end of the vertical rod; a pressing plate is arranged in the annular plate, and clamping nails are arranged at the four ends of the annular plate in a penetrating mode; and connecting blocks are arranged at the two ends of the annular plate, and clamping rods are arranged on the outer surfaces of the connecting blocks. According to the reinforcing device, through arrangement of the bearing rod, the stress support between the stand column and the transverse column can be effectively implemented, and the pressure of the transverse columns is reduced; the hoistingstrength of equipment is guaranteed, and the stress area of the stand column can be effectively increased through arrangement of the clamping rods on the two sides; and the safety and stability of the stand column are guaranteed, and the reinforcing effect is achieved; and the stress safety of the clamping rods is stabilized through fastening rods, and the effective reinforcing capacity is achieved.

    本发明属于起重机涉笔技术领域,尤其为一种悬臂吊起重机立柱加固装置,包括立柱,立柱上方垂直处设置有横柱,立柱的一侧设置有固定座,立柱与横柱的连接处设置有承重杆,横柱内部设置有凹槽。凹槽贯穿设置有第一螺钉,立杆的中端外表面设置有环形板,环形板的内部设置有压板,环形板的四端贯穿设置有卡钉,环形板的两端设置有衔接块,衔接块的外表面设置有夹持杆。本发明通过设置承重杆,可有效进行对立柱与横柱之间的受力支撑,降低了横柱的压力,保障设备的起重强度,通过设置两侧的夹持杆可有效的加强立柱的受力面积,保障立柱的安全平稳性,已达到加固的作用,且通过紧固杆更稳定了夹持杆的受力安全性,达到更有效的加固能力。
