The invention relates to the technical field of crane main beams, and discloses a crane main beam which comprises a main beam detection device body, through holes are formed in the left side and the right side of the main beam detection device body, a bell is welded to the bottom of the main beam detection device body, and an extrusion mechanism is welded to the top of the main beam detection device body. And a detection mechanism is welded in the main beam detection device main body. The main beam deflects, the main beam pushes the detection block at the bottom to vertically move downwards, the detection block drives the ejector rod to vertically move downwards in the sliding groove, the rotating rod on the fixing frame deflects, the conductive disc is driven by the driving block to deflect, and the top of the conductive disc leaves the uncharged area of the charged ring. And the electric power is transmitted to the bell through the electric wire, so that the bell makes a sound to remind a worker that the detection of the main beam is finished, and the effect of automatically reminding the worker that the detection is finished is achieved.

    本发明涉及起重机主梁技术领域,且公开了一种起重机主梁,包括主梁检测装置主体,所述主梁检测装置主体的左右两侧开设有通孔,所述主梁检测装置主体的底部焊接有响铃,所述主梁检测装置主体的顶部焊接有挤压机构,所述主梁检测装置主体的内部焊接有检测机构。通过主梁产生偏折,主梁将会推动着底部的检测块竖直向下移动,检测块将会带动顶杆在滑槽内部竖直向下移动,固定架上的转杆将会产生偏转,通过带动块带动导电盘产生偏转,导电盘的顶部将会离开带电环不带电区域,使得导电盘获得电力供应,通过电线将电力传递到响铃,使得响铃发出声响,提示工作人员主梁检测完毕,达到了自动提醒工作人员检测结束的效果。
