Principle of operation
When the lifting motor 3-2 drives the lifting drum 3-1 to rotate during descending, at the moment, the steel wire rope 7 can stretch downwards, the lower plate 2 and the lifting permanent magnet 10 can move downwards under the action of gravity, meanwhile, the lower sliding plate 4-3 fixed on the lower plate 2 can move downwards along with the lower plate 2, and the inner sliding plate 4-2 can descend along with the lower plate 2 under the action of gravity. When the upper limit block of the inner slide plate 4-2 contacts the protruding part of the lower end of the upper slide plate 4-1, the inner slide plate 4-2 keeps the position unchanged, and other parts continue to descend. When the lifting permanent magnet 10 contacts the sucked object, the position of the lifting permanent magnet 10 is kept still, other parts continue to descend, meanwhile, the telescopic rod 5-1 starts to retract, and the lifting permanent magnet rotating arm gradually rotates downwards under the action of dead weight. When the lifting permanent magnet rotating arm rotates to the lowest point, the hanging chain of the rotating arm begins to be loosened until the limiting block at the lower end of the inner sliding plate 4-2 contacts the protruding position at the upper end of the lower sliding plate 4-3, and the lifting hook descends to the lowest point.
When the lifting motor 3-2 is lifted, the lifting drum 3-1 drives the steel wire rope 7 to shrink, and then drives the lower plate 2 and the lifting hook to lift, meanwhile, the lower sliding plate 4-3 fixed on the lower plate 2 can lift along with the lifting, the telescopic rod 5-1 starts to stretch, the swinging arm hanging chain can be tensioned gradually, after the swinging arm hanging chain is tensioned, the lifting permanent magnet swinging arm can rotate upwards under the pulling of the hanging chain, meanwhile, the magnetic circuit of the lifting permanent magnet 10 starts to change, when the telescopic rod 5-1 stretches to a limiting position, the lifting permanent magnet swinging arm rotates for 90 degrees, the magnetic circuit finishes conversion, the lifting permanent magnet 10 attracts a sucked object, and the lifting permanent magnet 10 and the sucked object are lifted along with the continued shrinkage of the steel wire rope 7. When the lower end of the inner slide 4-2 contacts the lower plate 2, the inner slide 4-2 is lifted up together with the lower plate 2, and when the upper end of the inner slide 4-2 contacts the upper plate 1, the sucked object is lifted up to the highest position.
When the horizontal direction sways in the process of carrying cargoes, the sliding plates in the steel wire rope swaying prevention mechanism are matched through two parallel sliding grooves, so that swaying of the lower plate and the lifting hooks in the left-right direction can be restrained, the sliding grooves are trapezoidal, vertical sliding only can be tightly attached between the sliding plates, and swaying of the lower plate and the lifting hooks in the front-back direction can be restrained. Therefore, the wire rope anti-sway mechanism can suppress sway of the lower plate and the hooks in the horizontal direction. The outer side surface of each section of rigid telescopic rod in the lifting appliance anti-swing mechanism is tightly clung to the inner side surface of the protruding part of the bottom of the upper section and simultaneously the outer side surface of the protruding position of the top of each section is tightly clung to the inner side surface of the upper section, so that the telescopic rod can only move in the vertical direction and cannot incline in the horizontal direction, the distances among the four telescopic rods are fixed, and the lifting permanent magnet can be guaranteed to be always in the horizontal position.
