as shown in fig. 1 and 3, a cylinder doffer hanger comprises a hanging beam 1, a hanger and a lifting hook, wherein a lifting ring 2 is connected to the upper part of the hanging beam 1 through a lifting cable, two connecting parts 15 are arranged on the specific hanging beam 1, the lifting cable is connected with the lifting ring 2 and the connecting parts 15 through shackles 16, 2T double-ring buckles can be arranged between the shackles 16 connected with the connecting parts 15 and the lifting cable, the lifting hook is connected to the lower part of the hanging beam 1, and the specific lifting cable can be a lifting chain or a steel wire rope (the lifting chain is specifically and schematically adopted in the drawing); the hanging beam 1 extends axially to form a diameter-reduced displacement section 4 with an external thread, and a sliding sleeve 5 is screwed on the displacement section 4; the lifting hook comprises a first lifting hook 30 and a second lifting hook 31, which are approximately in an L shape, wherein the first lifting hook 30 is connected to the end part of the lifting beam 1 far away from the displacement section 4, the second lifting hook 31 is connected to the sliding sleeve 5, and the two openings of the first lifting hook 30 and the second lifting hook 31 face to opposite directions.

The use method comprises the following steps:

firstly, hinging two connecting parts 15 with shackles 16 through pin shafts, then taking out two hanging chains, respectively connecting one ends of the two hanging chains with the two shackles 16, then penetrating the two shackles 16 on a hanging ring 2, and then connecting the other ends of the two hanging chains with the two shackles 16 to complete the assembly of a hanging lock on the upper part of a hanging beam 1;

secondly, hooking the lower end of the wall body at one end of the cylinder doffer by the first lifting hook 30, and then adjusting the position of the second lifting hook 31 by screwing the sliding sleeve 5 to adapt to the length of the cylinder doffer to be lifted, thereby completing the binding of the cylinder doffer on the lifting appliance;

and thirdly, hoisting and discharging.

Example 2:

as shown in fig. 2 and 4, compared with embodiment 1, the difference is that the sliding sleeve 5 includes a positioning sleeve 50 and an adjusting sleeve 51, the positioning sleeve 50 is screwed on the displacement section 4 and has an accommodating cavity 50a in the axial direction; the adjusting sleeve 51 is formed by splicing a first half sleeve 51a and a second half sleeve 51b, the first half sleeve 51a and the second half sleeve 51b are respectively provided with a force application part 6 and a fastening part 7, the fastening parts 7 of the first half sleeve 51a and the second half sleeve 51b are connected through a first bolt 8, when the first bolt 8 fastens the first half sleeve 51a and the second half sleeve 51b, the first half sleeve 51a and the second half sleeve 51b are screwed on the displacement section 4, and the second hook 31 is connected to the force application part 6 of the second half sleeve 51 b; the adjusting sleeve 51 is partially sleeved in the accommodating cavity 50a, the first half sleeve 51a is matched with the upper part of the accommodating cavity 50a, the second half sleeve 51b and the bottom of the accommodating cavity 50a form a semi-annular movable groove 9, an expansion piece 10 and a top block 11 which is arranged on the expansion piece 10 and matched with the force application part 6 of the second half sleeve 51b are arranged in the movable groove 9, and the top block 11 is connected with a second bolt 12, so that when the first bolt 8 is adjusted, the top block 11 can radially displace in the movable groove 9. The positioning sleeve 50 is also provided with a wrench rod 13, and the wrench rod 13 is adopted to rotate the positioning sleeve 50, so that the operation is convenient, time-saving and labor-saving.

The use method comprises the following steps:

because the cylinder doffer also has the difference of wall thickness, and the distance between the transverse hook part of the L-shaped hook and the hanging beam 1 is fixedly arranged, because the lifting stability is ensured, the distance between the hook part of the transverse section of the hook and the hanging beam 1 cannot be too large, and when the thickness of the cylinder doffer wall body to be lifted is larger than the distance between the transverse hook part of the L-shaped hook and the hanging beam 1, the second hook 31 cannot hook the end wall body of the cylinder doffer; at this time, the first bolt 8 and the second bolt 12 can be firstly unscrewed in a moving direction, the second bolt 12 drives the ejector block 11 to move downwards in the moving groove 9 in a radial direction, the second half sleeve 51b which loses the limit of the first bolt 8 and the ejector block 11 moves downwards along with the second bolt until the second half sleeve is matched with the ejector block 11, and the elastic piece contracts and presses downwards along with the second half sleeve; because the second lifting hook 31 is arranged on the force application part 6 of the second half sleeve 51b, the second lifting hook 31 moves downwards along with the lifting lug half sleeve simultaneously, and the distance between the L-shaped transverse hook part of the second lifting hook 31 and the lifting beam 1 is adjusted, so that the hanger can be suitable for lifting cylinder doffers with large wall thickness; the distance between the cross section of the second hook 31 and the hanging beam 1 needs to be reduced, and the telescopic member 10 recovers the deformation resistance in the reverse operation to jack the jack block 11 upwards, i.e. jack the second half ring upwards.

Example 3: refer to FIG. 3

Compared with the above embodiment, the difference is that the hanging beam 1 is also provided with a cushion block 14 made of polyurethane material; the cushion block 14 plays a role in isolating the cylinder doffer from the hanging beam 1, and the cylinder doffer is prevented from being in contact with and worn by the hanging beam 1; the polyurethane material has good wear resistance, strength and shock absorption performance, and effectively isolates the cylinder doffer from the hanging beam 1.
