[0030] like Figure 1-3 As shown, the component lifting sling limiting device provided by the utility model comprises a sling body 1 and a sling rope 2 arranged at its lower end, the sling rope 2 comprises a first group of sling ropes 21 and a second group of sling ropes 22, a sling 7 is arranged at the lower end of the sling rope 2, the first group of sling ropes 21 is provided with a first U-shaped buckle 5; the second group of sling ropes 22 is provided with a second U-shaped buckle 6; a coarse adjustment rod 3 and a fine adjustment rod 4 are arranged between the first U-shaped buckle 5 and the second U-shaped buckle 6; the coarse adjustment rod 3 comprises a rod outer shell 31 and a rod inner core 32, both the rod outer shell 31 and the rod inner core 32 are provided with pin holes 33, and a fixing pin 34 is arranged in the pin hole 33; the fine adjustment rod 4 comprises a threaded sleeve 41 and an adjusting threaded rod 42, one end of the threaded sleeve 41 is connected to the coarse adjustment rod 3 through a connecting threaded rod 43, and one end of the threaded sleeve 41 is threadedly connected to the second U-shaped buckle 6 through the adjusting threaded rod 42.
[0031] like Figure 4As shown, when the utility model is used, first, mark the lifting rope 2 according to the lifting ring height or lifting hole depth of the component 8 such as the concrete block and the unloading plate, and the mark elevation of the first group of lifting ropes 21 and the second group of lifting ropes 22 are consistent. Then, the first U-shaped buckle 5 is installed at the mark of the first group of lifting ropes 21, and the nut of the first U-shaped buckle 5 is tightened to fix the first U-shaped buckle 5 on the first group of lifting ropes 21. The second U-shaped buckle 6 is installed at the mark of the second group of lifting ropes 22, and the nut of the second U-shaped buckle 6 is tightened to fix the second U-shaped buckle 6 on the second group of lifting ropes 22. Afterwards, according to the distance between the lifting rings or lifting holes of the components 8 such as concrete blocks and unloading plates, the distance between the first group of lifting ropes 21 and the second group of lifting ropes 22 is adjusted by pulling the inner rod core 32 of the rough adjustment rod 3, so that the distance between the first group of lifting ropes 21 and the second group of lifting ropes 22 is roughly consistent with the distance between the lifting rings or lifting holes of the components 8 such as concrete blocks and unloading plates, and the fixing pin 34 is inserted into the pin hole 33 to fix the outer rod shell 31 and the inner rod core 32. Finally, the distance between the first group of lifting ropes 21 and the second group of lifting ropes 22 is precisely adjusted by rotating the threaded sleeve 41 on the fine adjustment rod 4, so that the sling 7 at the lower end of the first group of lifting ropes 21 and the second group of lifting ropes 22 is consistent with the center of the lifting ring or lifting hole of the components 8 such as concrete blocks and unloading plates. When the components are lifted, the first group of lifting ropes 21 and the second group of lifting ropes 22 can be formed into a whole, so that the swing frequency and direction of the two groups of lifting ropes tend to be consistent, which greatly reduces the difficulty of synchronously entering the hole with the sling, and the number of workers in the auxiliary group of hooks can be reduced by 50%.
[0032] When the utility model is performing lifting operations on components 8 such as concrete blocks and unloading plates, a sling body 1 equipped with a coarse adjustment rod 3 and a fine adjustment rod 4 is connected to the lifting hook of the crane, and the sling operator directs the crane to make the center of the lifting hook perpendicular to the center point between the lifting rings or lifting holes of the components 8 such as concrete blocks and unloading plates, and the worker assists in rotating the sling body 1 equipped with the coarse adjustment rod 3 and the fine adjustment rod 4 to complete the precise positioning between the sling 7 and the lifting rings or lifting holes, and lowers the lifting hook of the lifting equipment to complete the overall entry of the sling body 1 into the hole.
[0033] like Figure 2 , 3 As shown, the first U-shaped buckle 5 and the second U-shaped buckle 6 both include a U-shaped ring 61 and a fixing plate 62, both ends of the fixing plate 62 are provided with fixing holes adapted to the U-shaped ring 61, and the middle of the fixing plate 62 is provided with a fixing groove 63 adapted to the sling 2. The U-shaped ring 61 and the fixing groove 63 form an annular structure adapted to the sling 2, the first U-shaped buckle 5 is fixed to the first group of slings 21, and the second U-shaped buckle 6 is fixed to the second group of slings 22, so that the sling body 1 can synchronously insert the sling 7 at the lower ends of the first group of slings 21 and the second group of slings 22 into the hole through the coarse adjustment rod 3 and the fine adjustment rod 4, thereby improving the construction efficiency.
[0034] like Figure 1 , 2As shown, the rod housing 31 is connected to the first U-shaped buckle 5 through the connecting rod 51, and the two ends of the connecting rod 51 are respectively welded to the rod housing 31 and the fixing plate 62. The connecting rod 51 and the fixing groove 63 are respectively located on both sides of the fixing plate 62, and the connecting rod 51 does not penetrate the fixing plate 62, which can prevent the connecting rod 51 from wearing the first group of suspension ropes 21, thereby improving construction safety.
[0035] like Figure 1 , 3 As shown, a threaded hole 64 is also provided in the middle of the fixing plate 62 of the second U-shaped buckle 6 to match the adjusting threaded rod 42. By rotating the threaded sleeve 41, the distance between the first group of lifting ropes 21 and the second group of lifting ropes 22 can be accurately adjusted, so that the slings 7 at the lower ends of the first group of lifting ropes 21 and the second group of lifting ropes 22 are aligned with the center of the lifting rings or lifting holes of the components 8 such as concrete blocks and unloading plates, so that the two groups of slings can be put into the holes synchronously, thereby improving the construction efficiency.
[0036] like Figure 1 , 3 As shown, the threaded hole 64 and the fixing groove 63 are respectively located on both sides of the fixing plate 62, and the adjusting threaded rod 42 does not penetrate the fixing plate 62, which can prevent the adjusting threaded rod 42 from wearing the second set of suspension ropes 22, thereby improving construction safety.
[0037] like Figure 1 , 2 As shown, the pin holes 33 are evenly arranged on the rod outer shell 31 and the rod inner core 32, and the interval between two adjacent pin holes 33 is 300mm. The rod outer shell 31 is made of a square tube with a specification of 100*100mm and a wall thickness of 3mm, and the rod inner core 32 is made of a square tube with a specification of 90*90mm and a wall thickness of 3mm. The pin holes 33 are punched at intervals of 300mm between the rod outer shell 31 and the rod inner core 32. By pulling the rod inner core 32, the distance between the first group of lifting ropes 21 and the second group of lifting ropes 22 can be adjusted, so that the distance between the first group of lifting ropes 21 and the second group of lifting ropes 22 is roughly consistent with the distance between the lifting rings or lifting holes of the components 8 such as concrete blocks and unloading plates, so that the two groups of lifting tools can enter the holes synchronously and the construction efficiency can be improved.
[0038] The sling 7 of the utility model is any one of a hook, a sling, a lifting ring, a lifting sucker, a clamp and a fork. The sling 7 is adapted to the lifting rings or lifting holes of components 8 such as concrete blocks and unloading plates.
