[0024] The following further elaborates on the above and additional technical features and advantages of the present utility model in conjunction with the accompanying drawings and embodiments. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them.

[0025] Embodiment:

[0026] As Figures 1-5 shown, the present utility model provides an assembled beam hoisting sling, which includes a sling main body 1. Two groups of straight slots 2 are opened at both ends of the sling main body 1. The two groups of straight slots 2 at the same end of the sling main body 1 are symmetrically arranged. A first suspension rod assembly 3 is sleeved inside the straight slot 2. Two groups of fixed suspension rod holes 4 are opened on both sides of the middle of the sling main body 1. A second suspension rod assembly 5 is sleeved inside the fixed suspension rod hole 4. A suspension rod limit seat 6 cooperating with the second suspension rod assembly 5 is installed at the top of the fixed suspension rod hole 4;

[0027] The second suspension rod assembly 5 moves upward along the fixed suspension rod hole 4. The end of the second suspension rod assembly 5 cooperates with the end of the suspension rod limit seat 6. The end of the second suspension rod assembly 5 is restricted by the suspension rod limit seat 6 to maintain the upward movement state, and the first suspension rod assembly 3 in the straight slot 2 remains in the original position.

[0028] The sling main body 1 includes structure holes 11. There are two groups of structure holes 11. Both groups of structure holes 11 are opened in the middle of the sling main body 1. The structure holes 11 penetrate the sling main body 1. The opened sling main body 1 can facilitate the hoisting operator to observe the relative position between the sling main body 1 and the beam box below the sling main body 1, so as to facilitate the adjustment of the hoisting position.

[0029] The sling main body 1 further includes connection seats 12. There are two groups of connection seats 12. The two groups of connection seats 12 are respectively fixed at the middle positions of both ends of the sling main body 1. The two groups of connection seats 12 are respectively connected to the hooks of the beam hoisting machine. The beam hoisting machine drives the sling main body 1 to move up and down through the cooperation of the hooks and the connection seats 12 to complete the hoisting of the beam body.

[0030] The first suspension rod assembly 3 includes a first suspension rod 31 and a first suspension rod nut 32. The first suspension rod 31 is sleeved inside the straight slot 2. The first suspension rod nut 32 is connected to the top end of the first suspension rod 31. The cooperation of the first suspension rod 31, the first suspension rod nut 32, the sling main body 1 and the straight slot 2 forms an adjustable hoisting device to adapt to the hoisting of beam boxes of different specifications.

[0031] The diameter of the first suspension rod 31 is the same as that of the straight notch 2. The outer wall of the first suspension rod 31 fits against the inner wall of the straight notch 2. The diameter of the first suspension rod nut 32 is larger than that of the straight notch 2. The straight notch 2 can laterally limit the first suspension rod 31, ensuring the stability of the setting state of the straight notch 2. At the same time, the first suspension rod 31 can move horizontally inside the straight notch 2, so as to make corresponding adjustments according to the opening position of the hanging hole on the beam box, and thus perform hoisting adaptation.

[0032] The second suspension rod assembly 5 includes a second suspension rod 51 and a second suspension rod nut 52;

[0033] The second suspension rod 51 is sleeved inside the fixed suspension rod hole 4. The diameter of the second suspension rod 51 is the same as that of the fixed suspension rod hole 4. The second suspension rod nut 52 is threadedly connected to the top of the second suspension rod 51. The second suspension rod nut 52 and the second suspension rod 51 cooperate with the hoisting tool body 1 to form a hoisting tool with a fixed specification.

[0034] The second suspension rod assembly 5 further includes a limiting plate 53. The limiting plate 53 is sleeved outside the second suspension rod 51, and the second suspension rod nut 52 is located between the hoisting tool body 1 and the second suspension rod nut 52. After the second suspension rod 51 and the second suspension rod nut 52 are lifted upward, the limiting plate 53 is pulled to move upward along the second suspension rod 51. After the limiting plate 53 moves upward to the top of the suspension rod limiting seat 6, horizontally moving the limiting plate 53 can make the limiting plate 53 rest on the top of the suspension rod limiting seat 6. The cooperation between the suspension rod limiting seat 6 and the limiting plate 53 can limit the fall of the second suspension rod nut 52.

[0035] Preferably, a contact plate 7 is formed at the bottom end of each group of fixed suspension rod holes 4. The bottom ends of several groups of contact plates 7 are in the same plane. When using the second suspension rod assembly 5 in the fixed suspension rod hole 4 for hoisting the beam box, the contact plate 7 can contact the beam box instead of the hoisting tool body 1, and a gap is formed between the hoisting tool body 1 and the beam box, and the connection state is observed through the gap.

[0036] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
