The working principle of the universal rotary lifting appliance structure for hoisting provided by the invention is as follows:

in this embodiment, the top of the hollow cylinder 1 is tightly connected with the lifting rope of the external lifting equipment, and in the initial state, the bottoms of the two existing inserting columns 24 are inserted into the corresponding grooves 22, so as to fix the sliding connection block 21;

when the goods are lifted, the device is firstly lowered to a specified height by using external lifting equipment, then the four hooks 12 are connected with hanging rings on the goods, then the goods are lifted a little to be separated from the ground, then the motor II is started, the corresponding internal thread pipes 15 can be driven to rotate by utilizing the meshing between the two gears II, meanwhile, the two internal thread pipes 15 can be driven to rotate simultaneously by utilizing the transmission between the synchronizing wheel and the synchronizing belt, so that the two adjusting screws 16 start to descend through the thread relation between the two adjusting screws and the adjusting screw 16, the box body 14, the box body III 17, the box body IV 18 and the pressure stabilizing plate 19 are driven to descend together until the pressure stabilizing plate 19 contacts the goods, the goods are compacted downwards, the spring I is compressed at the moment, the motor II is closed until the compression reaches a certain degree, and the goods at the moment are reliably compacted, the hanging ring on the hook is difficult to slip easily with the hook 12, and then the lifting work is carried out;

in later use, if the hooks 12 do not correspond to the positions of the hanging rings on the goods, in order to enable the hooks to correspond to the hanging rings, the bidirectional screw rod I7 can be rotated, so that the two connecting blocks I8 move away from or close to each other, the distance between the two box bodies II 9 is changed, the distance between the two groups of hooks 12 can be changed, the lifting work can be continued until the distance is adjusted, if the positions of the two longitudinal hooks 12 cannot correspond to the hanging rings, the bidirectional screw rod II 10 can be rotated, so that the two corresponding connecting blocks II 11 move away from or close to each other, the distance between the two longitudinal hooks 12 in the horizontal direction can be changed, and the lifting work can be carried out until the adjustment is finished;

in addition, if the goods to be lifted are small, when the two pressure stabilizing plates 19 cannot be pressed to the top of the goods, the output shafts of the two motors III can be started to rotate 90 degrees, so that the two cams 27 can be driven to rotate 90 degrees, in the rotating process of the cams 27, the convex ends of the cams can be in contact with the inner wall of the top of the frame 25, so that the frame 25 can be driven with the connecting plate 23 and the inserting columns 24 upwards, the springs are in a compressed state, the inserting columns 24 are also driven out of the grooves 22, then the two sliding blocks 21 are horizontally slid, the two sliding blocks 21 are driven to approach each other, so that the two box bodies four 18 can approach each other, the horizontal positions of the two pressure stabilizing plates 19 are changed until the horizontal positions of the two pressure stabilizing plates are adjusted to be approximate positions, then the horizontal positions of the sliding blocks 21 are slightly adjusted, one of the inserting columns 24 corresponds to the grooves 22, then the output shafts of the cabinet motors III are started to rotate 90 degrees again, the cam 27 and the frame 25 are separated, then the corresponding inserted column 24 is inserted into the groove 22 under the action of the second spring, and then corresponding hoisting work is carried out;

furthermore, if need carry out not equidirectional when putting to the goods, alright starter motor 4 utilizes the meshing of two gears 5, alright drive pivot 3 and rotate to can take hollow seat 2 to rotate, just so can make other whole parts except hollow cylinder 1 rotate, thereby can change the direction smoothly.

this device is through the rotation of two-way lead screw 7 and two-way lead screw 10 that set up, alright make the interval of two box bodys 9 adjust, and adjust the interval of two couples 12 on the vertical position, like this alright carry out corresponding adjustment to the position of four couples 12, thereby can correspond with the link on the goods, then can adapt to the work of lifting by crane of the goods of equidimension not, and, utilize the steady board 19 to the pushing down of goods, can tightly press the goods, make the stability of goods obtain further reinforcing, effectively prevent that it from taking place the condition that the small amplitude rocked when lifting by crane, in addition, utilize a plurality of settings of inserting post 24, alright adjust the horizontal position of steady board 19, thereby can satisfy the work of compressing tightly of less goods, application scope is wider.
