The invention provides a monitoring device for displaying a real-time lifting hook deflection angle during hoisting and a crane. A fixed pulley assembly a1 of the crane is hung on a lifting lug b2 ofa lifting arm through a connecting piece a3, one end of the connecting piece a3 is connected with the fixed pulley assembly a1 through a hinge shaft a2, the hinge shaft a2 is arranged in the directionperpendicular to the axis of a fixed pulley, and a platform face a6 perpendicular to a pulley block force acting line or a straight line parallel to the pulley block force acting line is arranged onthe connecting piece a 2. During hoisting, the included angle between the platform face a6 perpendicular to the pulley block force acting line and the horizontal plane or the angle of the straight line parallel to a pulley block lifting force acting line deviating from the plumb line is equal to the real-time lifting hook deflection angle in numerical value, the precision of the lifting hook deflection angle is detected on the platform face a6 and determined by an installed angle measuring instrument a7, the lifting hook deflection angle for displaying the angle of the pulley block force acting line deviating from the plumb line in real time is detected, and the lifting hook deflection angle of the crane is monitored in the whole hoisting process.

    本发明提供一种吊重时显示实时吊钩偏角监控装置及起重机,将起重机定滑轮组件a1经联接件a3吊挂于吊臂的吊耳b2上,所述联接件a3一端用绞接轴a2同所述定滑轮组件a1联接,并将所述绞接轴a2设在与定滑轮轴线相垂直方位,在所述联接件a2上设立与滑轮组力作用线垂直平台面a6或设立与滑轮组力作用线的平行直线;吊重时所述实时与滑轮组力作用线垂直平台面a6同水平面间夹角或实时与滑轮组提升力作用线的平行直线偏离铅垂线的角度,数值上均等于实时吊钩偏角,在所述平台面a6检测吊钩偏角的精度,由装设的角度测量仪a7确定,以检测显示实时所述滑轮组力作用线偏离铅垂线角度的吊钩偏角,吊装全过程监控起重机的吊钩偏角。
