The invention discloses a mast type aerial work platform and an overload protection method thereof.The mast type aerial work platform comprises a fence and a fly jib, one side of the fly jib is connected with a fly jib connecting rod, an overload protection mechanism is arranged between the fence and the fly jib, and the overload protection mechanism comprises a connecting rod mechanism and a travel switch; the connecting rod mechanism is connected with a bearing spring, and the bearing spring triggers the travel switch according to the deformation quantity generated by the bearing spring. The invention further provides a mast type aerial work platform overload protection method. The problems that the load accuracy of overload protection calculation of an existing aerial work platform is not high, and the cost needed by an overload protection scheme is high are solved. According to the overload protection device, the connecting rod mechanism in the overload protection mechanism is utilized, the travel switch and the bearing spring are matched, whether the load is overloaded or not can be accurately judged, real-time monitoring in the whole operation period is achieved, and the needed cost is low.

    本发明公开了一种桅杆式高空作业平台及其超载保护方法,一种桅杆式高空作业平台,包括围栏和飞臂,飞臂的一侧连接有飞臂连杆,围栏和飞臂之间设置有超载保护机构,超载保护机构包括连杆机构以及行程开关,连杆机构连接有承载弹簧,承载弹簧根据其产生的形变量来触发行程开关。还提出一种桅杆式高空作业平台超载保护方法;本发明解决了现有的高空作业平台超载保护计算的载荷准确度不高且超载保护方案所需成本较高的问题;本发明利用超载保护机构中的连杆机构,并配合行程开关以及承载弹簧,能够准确判断载荷是否超载,实现全作业周期实时监测,所需成本低。
