The invention relates to an anti-oblique-hoisting and anti-swing monitoring device for displaying a real-time hook deflection angle and a crane. The anti-oblique-hoisting and anti-swing monitoring device is characterized in that the hook deflection angle is detected and displayed, specifically, a fixed pulley assembly a1 of the crane is hung on a lifting lug b2 of a lifting arm b1 through a connecting piece a3 by using a shackle a5; the other 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 direction perpendicular to the axis of a fixed pulley; an angle measuring instrument a7 is mounted on the connecting piece a3 and connected with a crane controller; and vertical hoisting or oblique hoisting monitoring is achieved through centering hoisting according to the accurately-detected real-time hook deflection angle, or swing formed during parking is eliminated through double-pulse feedforward.

    本发明涉及一种显示实时吊钩偏角防斜吊防摇监控装置及起重机,其特点是:检测显示吊钩偏角:将起重机定滑轮组件a1经联接件a3用卸扣a5吊挂于吊臂b1的吊耳b2上,所述联接件a3另一端用绞接轴a2同所述定滑轮组件a1联接,并将绞接轴a2设在与定滑轮轴线相垂直方位,在所述联接件a3装设角度测量仪a7,并将所述角度测量仪与起重机控制器联接;依精确检测的实时吊钩偏角对中起吊实现垂直吊装或监控斜吊或用双脉冲前馈消除停车时所形成的摇摆。
