The invention discloses a platform crane auxiliary hook force unloading structure and method.The platform crane auxiliary hook force unloading structure comprises a lifting hook body, the lifting hook body comprises a hook part, two first vertical parts and a second vertical part, the first vertical parts and the second vertical part are welded and fixed to the two ends of the hook part correspondingly, and the two first vertical parts are welded and fixed to the two ends of the hook part correspondingly; and the two first vertical parts are arranged on the front side and the rear side of one end of the hook part correspondingly, and a butt joint plate is jointly welded and fixed to the top ends of the two first vertical parts. According to the platform crane auxiliary hook force unloading structure and method, through matched arrangement of the butt joint plate, the arc-shaped base plate, the threaded rod, the linkage plate, the reinforcing lead screw, the limiting plate and the first spring, after a plate-shaped hoisted object is placed in the hook part, the lifting hook body ascends, the linkage plate can be extruded to move through the arc-shaped base plate, and then the first spring is extruded; the purpose of unloading force is achieved through the first spring, and the situation that the lifting hook body collides and damages a plate-shaped lifted object is effectively avoided.

    本发明公开了平台吊机辅钩卸力结构及方法,包括吊钩本体,所述吊钩本体包括弯钩部、第一竖直部和第二竖直部,所述第一竖直部和第二竖直部分别焊接固定在弯钩部的两端,所述第一竖直部设置有两个,且分别设置在弯钩部一端的前后两侧,两个所述第一竖直部的顶端共同焊接固定有对接板,本发明涉及吊钩技术领域。该平台吊机辅钩卸力结构及方法,通过对接板、弧形垫板、螺纹杆、联动板、加固丝杆、限位板和第一弹簧的配合设置,在板状吊装物置于弯钩部中后,吊钩本体上升,可以通过弧形垫板挤压联动板移动,进而挤压第一弹簧,利用第一弹簧实现卸力的目的,有效避免吊钩本体对板状吊装物撞击损坏情况。
