[0028] In practical use, the temporary sling of this utility model is connected to the permanent lifting lug on the steel box girder to be lifted via a pin through the lug plate 1; then safe lifting can be carried out.

[0029] This utility model has a simple structure, is safe and reliable, is easy to disassemble, has a relatively simple construction process, high construction efficiency, and low construction cost.

[0030] Example 2:

[0031] according to Figure 1 The temporary sling shown is easy to disassemble, but differs from Embodiment 1 in that the connecting part is made of steel wire rope 5.

[0032] In practical use, the connection part uses steel wire rope 5, which not only meets the strength requirements of hoisting, but is also easy to implement.

[0033] Example 3:

[0034] according to Figure 1 The temporary sling shown is easy to disassemble, and differs from Embodiment 1 or Embodiment 2 in that: the ear plate 1 is a rectangular plate, and a pin hole is opened on one side of the rectangular plate.

[0035] In practical applications, the pin holes on the ear plate 1 are connected to the permanent lifting lugs on the steel box girder to be lifted by pin shafts, which ensures the stability of the connection and the safety of construction.

[0036] Example 4:

[0037] according to Figure 1 The temporary sling shown is easy to disassemble, and differs from Embodiment 3 in that one side of the ear plate 1 is cut into an arc shape.

[0038] In actual use, one side of the ear plate 1 is cut into an arc shape to avoid stress concentration during construction.

[0039] Example 5:

[0040] according to Figure 1 The temporary sling shown is easy to disassemble, and differs from Embodiment 3 in that the connecting sleeve 2 is threadedly connected to the adjusting member 3 and the adjusting member 3 is threadedly connected to the anchor cup 4.

[0041] In some embodiments, the inner wall of one end of the connecting sleeve 2 is provided with a thread that matches the adjusting member 3.

[0042] In some embodiments, the adjusting member 3 is a screw.

[0043] In this embodiment, the screw has positive and negative threads at both ends.

[0044] In some embodiments, one end of the anchor cup 4 is provided with a connecting cavity for connecting with the adjusting member 3, and the inner sidewall of the connecting cavity is provided with a thread that matches the adjusting member 3. In this embodiment, the anchor cup 4 and the wire rope 5 are connected and fixed by casting.

[0045] In practical applications, the connecting sleeve 2 adopts the above technical solution, which can easily adjust the total length of the temporary sling that is easy to disassemble by twisting, thereby ensuring that the hoisting work can be carried out safely, stably and smoothly.

[0046] Example 6:

[0047] according to Figures 1-4 The temporary sling shown differs from Embodiment 1 in that: the connecting part uses a steel wire rope 5; the ear plate 1 is a rectangular plate with a pin hole on one side; one side of the ear plate 1 is cut into an arc shape; the connecting sleeve 2 is threadedly connected to the adjusting component 3, and the adjusting component 3 is threadedly connected to the anchor cup 4; the inner wall of one end of the connecting sleeve 2 is provided with a thread matching the adjusting component 3; the adjusting component 3 is a screw; one end of the anchor cup 4 is provided with a connecting cavity for connecting with the adjusting component 3, and the inner wall of the connecting cavity is provided with a thread matching the adjusting component 3. In this embodiment, the anchor cup 4 and the steel wire rope 5 are connected and fixed by casting.

[0048] In practical use, during the hoisting stage of the steel box girder 9, the cable-free girder segment is hoisted to the designed position using hoisting equipment. Then, one end of the temporary sling 8 is connected to the cable-free girder segment using a pin through a pin hole on the ear plate 1, suspending it in the air without the need for a temporary girder support. The other end of the temporary sling 8 is connected to the straddle-type cable clamp 6 connected to the main cable 7 using a pin through a pin hole on the ear plate 1 before hoisting begins. After all the steel box girders 9 of the suspension bridge are hoisted and welded, the total length of the present invention is increased by tightening the screw that acts as an adjusting component 3, thereby gradually reducing the stress on the temporary sling 8 until the screw that acts as an adjusting component 3 is unscrewed, completing the removal of the temporary sling 8 and the completion of the suspension system conversion. After the bridge is completed, the temporary sling 8 is removed, as follows: Figure 2 , Figure 3 and Figure 4 As shown.
