The two ends of the rolling actuator 28 are respectively hinged with the hanger 24 and the swing frame 22, and the action of the rolling actuator makes the hanger 24 rotate on the end surface of the swing frame 22, and the turning angle of the hoisted heavy object can be controlled by the rotation of the hanger 24. The roll-over stand 21 is arranged at the left side and the right side of the swing frame 22 and is connected with the transverse frame 23 in a sliding way, the lower end of the roll-over stand 21 is respectively provided with a front pin shaft 211 and a rear pin shaft 212, the roll-over seat 51 of the connecting piece 50 is hinged with the roll-over stand 21 through the front pin shaft 211, one end of the roll-over actuator 20 is hinged with the roll-over stand through the rear pin shaft 212, and the other end of the roll-over actuator is hinged with the sliding block through the power support lug 53 of the connecting piece 50. The transverse moving frame 23 is provided with a connecting pin shaft 231, and the transverse moving frame 23 is hinged with the swing frame 22 through the connecting pin shaft 231. The two ends of the transverse moving actuator 27 are respectively hinged on the turning frame 21 and the transverse moving frame 23, the transverse moving frame 23 can be controlled to move through the action of the transverse moving actuator, the turning frame 21 and the swing frame 22 can slide left and right relatively, the distance that the turning frame 21 extends out of the two sides of the swing frame 22 is controlled, and therefore transverse moving positioning adjustment of the lifting appliance 24 is achieved. Two ends of the swing actuator 26 are respectively hinged with the swing frame 22 and the transverse frame 23, and the swing actuator 26 controls the transverse frame 23 and the swing frame 22 to rotate relatively to drive the lifting appliance 24 to realize the swing function.

When the weight and the hoisting system (i.e. the hoisting point of the spreader and the hoisting point of the weight) have a lateral deviation, lateral fine adjustment needs to be performed before hoisting, and the traverse actuator 27 causes the roll-over stand 21 and the swing frame to move relatively, so that the spreader 24 (and the auxiliary spreader mounted on the auxiliary spreader interface 25) mounted on the swing frame 22 changes the relative position between the spreader 24 and the weight along with the change of the lateral position of the swing frame 22, thereby realizing the lateral positioning adjustment of the spreader 24. When the heavy object and the hoisting system 2 have longitudinal deviation, the longitudinal movement actuator 29 is started, the longitudinal movement actuator 29 enables the sliding block 14 to slide on the longitudinal sliding rail 13, the hoisting system 2 is driven to slide and position back and forth on the longitudinal sliding rail 13, and then longitudinal positioning adjustment of the hoisting tool 24 relative to the heavy object is completed. When the heavy object has angular deviation relative to the hoisting system 2, the swing actuator 26 drives the swing frame 22 and the lifting appliance 24 thereon to complete multi-angle swing on the transverse frame 23, so as to realize swing positioning adjustment of the lifting appliance 24. When a certain angle deviation exists between the hoisting point of the weight and the hoisting point of the hanger 24, the hanger 24 is rotated on the swing frame 22 by multiple angles through the rolling actuator 28, so that the rolling positioning adjustment is realized, and the connection between the hanger 24 and the weight is ensured. After the heavy object is hung, the heavy object is moved to a falling point, and if the heavy object needs to be turned, the turning actuator 20 enables the hoisting system 2 to rotate around the rear pin shaft 212 by a plurality of angles, so that the heavy object can be turned and turned, and the requirement of the falling angle of the heavy object is met.
