When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0026] Example 1

[0027] like Figure 1 , Figure 2 As shown, the present embodiment is a high-speed steel roll transfer lifting device, comprising a crane body 1 and a roll 9, a first steel cable 101 is arranged on the crane body 1, a hook assembly 102 is slidably fitted on the first steel cable 101, a roller shaft 901 is arranged at both ends of the roll 9, a sleeve 2 is connected to the lower end of the hook assembly 102, two groups of second steel cables 3 are connected to the lower end of the sleeve 2, and a lifting ring 4 which penetrates the roller shaft 901 is connected to the movable end of the second steel cable 3, and the radius of the lifting ring 4 is smaller than the radius of the roll 9 and larger than the radius of the roller shaft 901;

[0028] A long rod 5 is movably inserted in the sleeve 2, and one end of the long rod 5 located inside the sleeve 2 is connected to a first screw 6. The movable end of the first screw 6 movably passes through a first limiting groove 201 provided on the sleeve 2 and is threadedly connected to a first nut 7. The first screw 6 passes through the first limiting groove 201 to prevent the long rod 5 and the limiting ring 8 from rotating. One end of the long rod 5 located outside the sleeve 2 is connected to the limiting ring 8, and the second steel cable 3 passes through the limiting ring 8; the long rod 5 drives the limiting ring 8 to move downward, and the limiting ring 8 limits the second steel cable 3, so that the lifting ring 4 is in close contact with the roller 9.

[0029] When lifting and transporting the roller 9, the lifting ring 4 is sleeved on the roller shaft 901, and the long rod 5 is moved to the outside of the casing 2. The long rod 5 drives the limiting ring 8 to gradually approach the movable end of the steel cable 3 and limit it until the lifting ring 4 is in close contact with the roller 9 and the distance between the movable ends of the two steel cables 3 is fixed. After the long rod 5 is moved into place, the first nut 7 is rotated on the first screw 6 until it abuts against the outer wall of the casing 2. The relative positions of the long rod 5 and the casing 2 are fixed, and at the same time, the relative positions of the steel cable 3, the lifting ring 4 and the roller 9 are fixed;

[0030] In the technical solution of the high-speed steel roller transfer sling, after the lifting ring 4 is mounted on the roller shaft 901, the position of the limiting ring 8 is changed to make the lifting ring 4 in close contact with the roller 9, and the distance between the movable ends of the two steel cables 3 is fixed, thereby improving the stability of the roller 9 during lifting and transfer.

[0031] like Figure 3 As shown, a receiving rod 801 is provided between the limiting ring 8 and the long rod 5 and they are connected through the receiving rod 801, and two through cavities 802 are formed between the limiting ring 8, the long rod 5 and the receiving rod 801, and the two groups of second steel cables 3 pass through the two through cavities 802 respectively; the second steel cables 3 are limited inside the through cavities 802, so as to reduce the shaking degree when the rolling roller 9 is transported and lifted, and improve the stability.

[0032] like Figure 4 As shown, the lifting ring 4 includes an arc-shaped sleeve 401 which is open at one end and closed at the other end, the closed end of the arc-shaped sleeve 401 is connected to a rope 403, the movable end of the rope 403 passes through the open end of the arc-shaped sleeve 401 and extends to the interior of the arc-shaped sleeve 401, the movable end of the rope 403 is connected to a block 404, the block 404 is connected to a second screw 405, the movable end of the second screw 405 movably passes through a second limiting groove 402 provided on the arc-shaped sleeve 401 and is threadedly connected to a second nut 406, and the second limiting groove 402 is provided on the outer wall of the arc-shaped sleeve 401.

[0033] When the lifting ring 4 is sleeved on the roller 901, the roller 901 is located on the arc sleeve 401, the second screw 405 is placed in the second limiting groove 402, and the block 404 is moved inside the arc sleeve 401 until the rope 403 contacts the upper part of the roller 901, and the second nut 406 is rotated on the second screw 405 until it abuts against the outer wall of the arc sleeve 401, and the relative positions among the arc sleeve 401, the rope 403 and the block 404 are fixed;

[0034] The lifting ring 4 in the technical solution and the arc sleeve 401 bear the weight of the rolling roller 9 and the roller shaft 901, and the rope 403 limits the position of the upper part of the roller shaft 901. When the roller shaft 901 is located inside the lifting ring 4, the stability is high. The setting of the lifting ring 4 can adapt to roller shafts 901 of different radii.

[0035] like Figure 4 As shown, the second steel cable 3 includes a first cable body 301 connected to the sleeve 2, and the movable end of the first cable body 301 is connected to two second cable bodies 302. The movable ends of the two second cable bodies 302 are respectively connected to the closed end and the open end of the arc sleeve 401. When the lifting ring 4 is sleeved on the roller shaft 901 and subjected to force, the arc sleeve 401 is kept at the bottom as a support member that bears the weight of the roller 9. The rope 403 is a limiter that limits the position of the upper part of the roller shaft 901 to ensure the stability of the roller 9 during lifting and transportation.
