The invention relates to the technical field of hoisting machines, and discloses a hoisting machinery safety early warning method and equipment, the hoisting machinery safety early warning equipment comprises a hoisting arm, a hoisting rope and a hook, an outer sleeve is fixedly arranged at the bottom of the hoisting arm, two arc-shaped plates are symmetrically arranged in the outer sleeve, the hoisting rope penetrates through the space between the two arc-shaped plates, and connecting rods are fixedly arranged on the sides, away from each other, of the two arc-shaped plates; first cavities are formed in the two sides of the outer sleeve correspondingly, extrusion blocks are arranged in the two first cavities correspondingly, first springs are fixedly arranged on the side walls of the extrusion blocks, the other ends of the first springs are fixedly connected with the side walls of the first cavities correspondingly, touch sensors are fixedly arranged on the tops of the two first cavities correspondingly, and the extrusion blocks can make contact with the touch sensors. The ends, away from the arc-shaped plate, of the two connecting rods penetrate into the two first cavities correspondingly and are fixedly connected with the side walls of the two extrusion blocks correspondingly. According to the safety early warning method and equipment for the hoisting machinery, the shaking amplitude of the hoisting rope can be limited, and the danger of hoisting an object is reduced.

    本发明涉及起吊机技术领域,且公开了一种起吊机械安全预警方法及设备,包括起吊臂、吊绳和挂钩,起吊臂的底部固定设有外套管,外套管的内部对称设有两个弧形板,吊绳穿过两个弧形板之间,两个弧形板相背离的一侧均固定设有连接杆,外套管的两侧均设有第一空腔,两个第一空腔的内部均设有挤压块,挤压块的侧壁固定设有第一弹簧,第一弹簧的另一端与第一空腔的侧壁固定连接,两个第一空腔的顶部均固定设有触碰传感器,挤压块可与触碰传感器接触设置,两个连接杆远离弧形板的一端分别贯穿至两个第一空腔的内部并分别与两个挤压块的侧壁固定连接。该一种起吊机械安全预警方法及设备,能够对吊绳的晃动幅度制约,降低吊装物体的危险性。
