Problems solved by technology

[0002] Cable crane is a kind of lifting and handling machinery widely used in ports, workshops, electric power, construction sites and other places. The name of crane is the unified title of lifting machinery. Cable crane mainly includes lifting mechanism, operating mechanism, luffing mechanism, Slewing mechanism and spreader, etc., but the existing spreader has certain defects: 1. The existing spreader can only clamp from the outer surface of the lifting object, which is very inconvenient for lifting the barrel with a smooth outer surface. The tool is connected to the steel of the crane through the lifting ring. During the lifting process, there is a risk that the steel cable hook will fall off from the lifting ring. 3. Due to the shaking during the lifting process, the lifting object will drive the steel cable to rotate, causing the steel cable to twist. , easy to break at the torsion

Abstract

The invention provides a lifting appliance for a steel cable crane. The lifting appliance for the steel cable crane comprises a first lifting seat and a second lifting seat, the first lifting seat islocated right above the second lifting seat, a movable shaft is movably installed in the middle between the first lifting seat and the second lifting seat, a first lifting arm is movably installed atthe edge of the first lifting seat, a first rotating shaft is movably installed between the first lifting arm and the first lifting seat, a second lifting arm is movably installed at the lower end ofthe first lifting arm, and a third rotating shaft is movably installed between the second lifting arm and the first lifting arm. According to the lifting appliance for the steel cable crane, clampingand hoisting can be carried out on a hoisted object from the outer surface of the hoisted object, and meanwhile, internal hoisting can be carried out on objects with smooth outer surfaces of barrels,so that the hoisting modes are diversified, and hoisting of most objects is achieved; fixing a steel cable is carried out after the steel cable is connected with a hoisting ring, so that the steel cable is prevented from being disengaged from the hoisting ring in the hoisting process; and the hoisting ring drives the steel cable and a hoisting seat to rotate relatively by using a bearing, so thatthe steel cable is prevented from being broken due to torsion.
