in the above process, when the upper connecting plate 1 continues to move downwards, the sleeve 6 continues to move downwards, at this time, the sleeve 6 and the lifting column 12 and the fixing unit 17 generate relative displacement, when the first pressing surface 21 on the pressed block 1703 contacts the first pressing surface 24 on the outer wall of the first pressing block 1401 and presses, at this time, the pressed block 1703 moves towards the depth of the groove body 1702 and effectively presses the pressing spring 1704 until the first pressing block 1401 is dislocated from the pressed block 1703, at this time, the pressed block 1703 pops up under the reset action of the pressing spring 1704, the bottom plane of the pressed block 1703 is lapped on the top end of the first pressing block 1401, at this time, the outer side of the hook claw 3 completely contacts the smooth outer wall of the barrel body, and it is required to be explained here that: when the lifting device drives the device to move upwards after the process is realized, at the moment, as: the bottom plane of the pressed block 1703 is lapped on the top of the first pressing block 1401, so that the sleeve 6 and the lifting column 12 cannot move relatively in the upward moving process, and the screw rod 5 is kept relatively static, so that when the whole device moves upward, the screw rod 5 moves upward along with the whole device, the magnet 7 slides relatively with the screw rod 5, and the magnet 7 is always adsorbed on the top of the barrel body;
then, the lifting device drives the device to move upwards, the claw 3 moves upwards along with the device until the claw 3 is hooked on the protruding part at the top end of the barrel body, the device can drive the barrel body to transfer, after the barrel body moves to a preset position, the lifting device gradually lowers the device, the device drives the barrel body to move downwards until the barrel body contacts with the ground, the barrel body is kept stationary at the moment when the device is continuously lowered, the claw 3 moves downwards along the surface of the barrel body until the telescopic unit 8 is contracted to the shortest distance again, the magnet 7, the screw rod 5, the lifting column 12 and the fixing unit 17 are kept stationary again at the moment, and the driving unit 9 cannot act at the moment because the claw 3 does not have a displacement space for moving inwards at the moment, the gear 901 and the screw rod 5 are kept relatively stationary, the lower connecting plate 2 and the driving unit 9 are kept stationary, the upper connecting plate 1 and the sleeve 6 move downwards under the action of gravity, at this time, the sling between the upper connecting plate 1 and the lower connecting plate 2 is in a bending state and is not straightened any more, at this time, the locking unit 14 moves downwards along with the sleeve 6, when the second compression surface 25 of the outer wall of the third compression block 1403 contacts with the second compression surface 22 at one end of the compression block 1703, the second compression surface 25 contacts with the second compression surface 22 (because the bottom protruding part of the limiting rod 1802 is located at the uppermost part of the lifting groove 1801, the third compression block 1403 cannot move upwards), the compression block 1703 moves to the depth of the groove body 1702 again, and presses the compression spring 1704 again until the compression block 1703 passes over the top end of the third compression block 1403 and moves upwards, the compression spring 1704 drives the compression block 1703 to reset, and after the compression block 1703 pops out, the third compression surface 23 at the end of the compression block 1703 contacts with the third compression surface 26 of the outer wall of the second compression block 1402;
at this time, the lifting device is controlled to drive the whole device to move upwards, at this time, the whole weight of the fixing unit 17 is pressed on the second pressing block 1402, the second pressing block 1402 presses the connecting spring 1803, and drives the limiting rod 1802 to move downwards along the lifting groove 1801 until the third pressing block 1403 completely enters the inner cavity of the accommodating groove 1404, at this time, the connecting position of the second pressing block 1402 and the third pressing block 1403 is completely overlapped with the top edge of the first pressing block 1401, when the sleeve 6 moves upwards along with the upper connecting plate 1, at this time, the second pressing block 1402 has no downward moving space, so that the pressing force is reversely given to the pressed block 1703, and when the pressing block 1703 is misplaced with the bottom end of the first pressing block 1401 (namely, is positioned below the top end of the first pressing block 1401), the misplacement unlocking of the first pressing block 1401 and the fixing unit 17 can be realized;
at this time, the lifting device continues to move upwards, the lifting device drives the upper connecting plate 1 and the sleeve 6 to move upwards until the sling between the upper connecting plate 1 and the lower connecting plate 2 is straightened, at this time, the lower connecting plate 2 starts to move upwards under the stress, and the magnet 7 continues to be adsorbed at the top end of the barrel body at this time, because the screw rod 5 cannot rotate under the limiting action of the lifting column 12, at this time, the lower connecting plate 2 moves upwards relative to the screw rod 5, namely: the gear 901 moves upwards relative to the screw rod 5, at the moment, the gear 901 rotates under the action of the first ball, so that the four racks 902 rotate reversely, the racks 902 drive the four connecting rods 403 to simultaneously move outwards through the connecting piece 404 and the sliding plate 401, so that the clamping of the claw 3 to the barrel body is relieved, after the connecting rods 403 move to the outermost side, no space for continuing to move outwards exists, at the moment, the gear 901 cannot continue to rotate, meanwhile, the connecting disc 1701 contacts with the bottom end of the inner cavity of the sleeve 6, and the lifting device pulls the screw rod 5 to be separated from the magnet 7 and the barrel body;
when the barrels with different diameters are lifted, the height of the positioning unit 11 can be adjusted to adapt to the barrels with different diameters, and the operation is as follows: firstly, the positioning bracelet 1101 is rotated circumferentially, the positioning bracelet 1101 drives the locking head 1104 to rotate, the arc-shaped end face of the locking head 1104 is in contact with the inner cavity of the clamping groove 1105, at the moment, the locking head 1104 is forced to move towards the deep part of the limiting hole 1102, the reset spring 1103 is forced to be compressed until the locking head 1104 and the clamping groove 1105 are misplaced (namely, one locking head 1104 is positioned between the two clamping grooves 1105), and in the process, the positioning bracelet 1101 rotates on the outer wall of the rotating block 19 through the circumferential groove 20;
afterwards, the positioning bracelet 1101 is pulled down (the diameter of the barrel is larger) or moved up (the diameter of the barrel is smaller) until the positioning bracelet 1101 moves to a preset height, and then the positioning bracelet 1101 is rotated to align the locking head 1104 with the clamping groove 1105, and the reset spring 1103 resets to drive the locking head 1104 to clamp into the clamping groove 1105 again, so that the lifting operation can be performed on barrels with different diameters, and the following needs to be described: when the positioning bracelet 1101 moves downwards, the locking unit 14 is driven to move downwards along the positioning column 16, so that the distance between the fixing unit 17 at the lowest position and the locking unit 14 is shortened, and therefore, when the fixing unit 17 displaces, the fixing unit 17 can displace by a relatively small distance to achieve the clamping with the locking unit 14, the displacement distance of the fixing unit 17 is the displacement distance of the screw rod 5 relative to the lower connecting plate 2, so that the rotation angle of the gear 901 is reduced, the displacement distance of the rack 902 is small, the aim of synchronous inward displacement distance of the four connecting rods 403 is achieved, otherwise, when the positioning bracelet 1101 moves upwards, the distance between the fixing unit 17 at the lowest position and the locking unit 14 is increased, the aim of synchronous inward displacement distance of the four connecting rods 403 is achieved, and the aim of lifting barrels of different sizes by a single lifting tool is achieved.
