In order to improve the hoisting stability of the hoisting crossbeam 1, a plurality of hoisting rolls 6 can be provided to hoist the hoisting crossbeam 1 stably in all directions, and the number of hoisting rolls 6 is set according to the length of the hoisting crossbeam 1 and the process requirements, and the side wall thickness of the hoisting roll 6 is not less than 1 cm;

[0032] An extension component is set to prevent the lifting beam 1 from tilting due to the contact and movement between the lifting beam 1 and the mounting beam 2. The extension component is symmetrically arranged on one side of the lifting beam 1 close to the lifting roll 6, and the extension component includes two extension steel frames 4. The upper end of the lifting beam 1 contacts the lower end of the mounting beam 2. The two extension steel frames 4 are welded and symmetrically arranged on both sides of the lifting beam 1, and the upper ends of the two extension steel frames 4 contact the lower ends of the mounting beam 2 respectively. The lifting beam 1 is located at the lower end of the extension steel frame 4 and is horizontally welded with an assembly plate 5. The lifting roll 6 is vertically welded and arranged at the center upper end of the assembly plate 5. The assembly plate 5 is located on one side of the lifting roll 6 and is penetrated by a through groove. A center gap groove 7 is provided in the center of the lifting beam 1. The lifting roll 6 vertically penetrates the center gap groove 7 and is welded to the lifting beam 1. The lifting roll 6 is convenient for the lifting bracket 19 or other slings to be penetrated and connected;

[0033] Stainless steel plates 9 are welded on both sides of the assembly plate 5 located at the through groove. The sling 3 includes a lifting bracket 19 and a lifting rod 20. The upper end of the lifting rod 20 is in contact with the lower ends of the two stainless steel plates 9. The inner wall of the lifting roll 6 is symmetrically provided with a plurality of reinforcing ribs 8. The lower end of the lifting bracket 19 vertically moves through the lifting roll 6 and the through groove, and the lifting rod 20 is fixedly sleeved on the lower end of the lifting bracket 19 passing through the assembly plate 5. Two guide strips 10 are horizontally symmetrically provided on both sides of the lower end of the mounting beam 2 near the lifting beam 1, and one side of the two guide strips 10 is respectively fitted with the side edges of the extended steel frame 4. The reinforcing ribs 8 can increase the supporting strength of the lifting roll 6. The stainless steel plate 9 can improve the smooth movement and adjustment effect of the lifting beam 1 through its own metal properties. The guide strip 10 can guide the lifting beam 1 when the lifting beam 1 moves horizontally. The direction of the lifting beam 1 is the same as that of the lifting roll 6.

[0034] In this embodiment: the rolled hoisting roll 6 is welded to the assembly plate 5 in advance, and then the hoisting roll 6 passes through the central gap groove 7 of the hoisting beam 1 and is welded. When the hoisting beam 1 is hoisted and connected, the sling 3 passes through the hoisting roll 6 of the hoisting beam 1 and supports the hoisting beam 1.

[0035] Embodiment 2: On the basis of embodiment 1, a push adjustment component is provided to adaptively fine-tune the assembly position of the hoisting beam 1. The push adjustment component is provided on the side of the hoisting beam 1 close to the mounting beam 2. The push adjustment component includes a wedge-shaped fixing member 11 and two adjustment control cylinders 16. The wedge-shaped fixing member 11 is welded on the side of the upper end of the hoisting beam 1 close to the mounting beam 2. Two first connecting ears 12 are symmetrically provided on one side of the wedge-shaped fixing member 11. Two second connecting ears 13 are symmetrically provided on one side of the mounting beam 2 close to the wedge-shaped fixing member 11. The two first connecting ears 12 are arranged opposite to the two second connecting ears 13. The first connecting ears 12 and the second connecting ears 11 are arranged opposite to each other. A combination connection groove 14 is provided on one side of the first connection ear 12 and the second connection ear 13, and a push constraint groove 15 is provided on the far side of the combination connection groove 14. U-shaped assembly frames 17 are fixed on both sides of the two adjustment control cylinders 16, and a push rod 18 is welded on one side of the U-shaped assembly frame 17. The two push rods 18 of the adjustment control cylinder 16 are horizontally inserted into the combination connection groove 14 of the first connection ear 12 and the second connection ear 13 respectively. The first connection ear 12 and the second connection ear 13 provided on the hoisting cross beam 1 and the mounting beam 2 are convenient for assembling the adjustment control cylinder 16 through the combination connection groove 14, and are convenient for removal after use;

[0036] The width of the push constraint groove 15 is equal to the diameter of the push rod 18, and the length of the push constraint groove 15 is greater than the radius of the push rod 18. When the adjustment control cylinder 16 moves the hoisting beam 1 horizontally, the two push rods 18 of the adjustment control cylinder 16 are respectively inserted into the push constraint grooves 15 of the first connecting ear 12 and the second connecting ear 13. When it is necessary to move and fine-tune the position of the hoisting beam 1, the two adjustment control cylinders 16 with U-shaped assembly frames 17 and push rods 18 are placed between the first connecting ear 12 and the second connecting ear 13, and the two push rods 18 are respectively inserted into the combined connecting grooves 14 from above. As the adjustment control cylinder 16 expands, the two push rods 18 are respectively inserted into the first connecting ear 12 and the second connecting ear 13. In the push constraint groove 15 of the first connecting ear 12 and the second connecting ear 13, the push constraint groove 15 can limit the push rod 18 from being separated from the first connecting ear 12 and the second connecting ear 13, thereby maintaining the stable placement of the adjustment control cylinder 16. When the mounting beam 2 remains stable, the lifting beam 1 can be moved, and then the mounting beam 2 and the lifting beam 1 can be fixed. At this time, the adjustment control cylinder 16 can be retracted with an appropriate stroke and removed from the first connecting ear 12 and the second connecting ear 13. Then, a support is welded between the wedge-shaped fixing piece 11 and the mounting beam 2 through a metal rod, or a U-shaped assembly frame 17 is respectively set at both ends of the basket bolt to perform support and tension limiting in the same way.
