During the hoisting process, lifting equipment is often required. Since it is a suspended hoisting, after the hoisting crossbeam is connected to the support mechanism, under the action of the hoisting crossbeam's own weight, when it is necessary to adjust the horizontal position of the hoisting crossbeam according to the construction requirements, the operation is cumbersome, inconvenient, time-consuming and labor-intensive.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Please see the appendix Figure 1-8 This application provides the following technical solutions.

[0031] Example 1: A steel-concrete beam hoisting mechanism includes a hoisting beam 1 and an installation beam 2. The hoisting beam 1 and the installation beam 2 are arranged in a cross pattern. The hoisting beam 1 is located below the installation beam 2 via a hoisting assembly. The hoisting assembly includes a lifting device 3 and a hoisting coil 6. To improve the hoisting stability of the hoisting beam 1, multiple hoisting coils 6 can be set to hoist the hoisting beam 1 stably from all directions. The number of hoisting coils 6 is set according to the length of the hoisting beam 1 and the process requirements, and the side wall thickness of the hoisting coil 6 is not less than 1cm.

[0032] The extension components are designed to prevent tilting caused by contact movement between the lifting beam 1 and the installation beam 2. The extension components are symmetrically arranged on the side of the lifting beam 1 near the lifting coil 6, and include two extension steel frames 4. The upper end of the lifting beam 1 contacts the lower end of the installation beam 2. The two extension steel frames 4 are welded symmetrically 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 installation beam 2. An assembly plate 5 is horizontally welded to the lower end of the extension steel frame 4 of the lifting beam 1. The lifting coil 6 is vertically welded to the upper center of the assembly plate 5. A through groove is opened through the assembly plate 5 on one side of the lifting coil 6. A central gap groove 7 is provided in the center of the lifting beam 1. The lifting coil 6 is vertically inserted through the central gap groove 7 and welded to the lifting beam 1. The lifting coil 6 facilitates the through connection of the lifting bracket 19 or other lifting devices.

[0033] Stainless steel plates 9 are welded to both sides of the assembly plate 5 in the through groove. The lifting device 3 includes a lifting bracket 19 and a lifting rod 20. The upper end of the lifting rod 20 contacts the lower ends of the two stainless steel plates 9. Several reinforcing ribs 8 are symmetrically provided on the inner wall of the lifting roll 6. The lower end of the lifting bracket 19 vertically and movably passes through the lifting roll 6 and the through groove. The lifting rod 20 is fixedly sleeved at the lower end of the lifting bracket 19 that passes through the assembly plate 5. Two guide strips 10 are horizontally and symmetrically provided on both sides of the lower end of the installation beam 2 near the lifting crossbeam 1. One side of each guide strip 10 is attached to the side of the extended steel frame 4. The reinforcing ribs 8 can improve the support strength of the lifting roll 6. The stainless steel plates 9 can improve the smoothness of the movement adjustment of the lifting crossbeam 1 through their own metal properties. The guide strips 10 can guide the lifting crossbeam 1 when it moves horizontally. The direction of the lifting crossbeam 1 is the same as the direction of the lifting roll 6.

[0034] In this embodiment: the hoisting coil 6 is pre-welded to the assembly plate 5, and then the hoisting coil 6 passes through the center gap groove 7 of the hoisting beam 1 and is welded. When the hoisting beam 1 is hoisted and connected, the lifting device 3 passes through the hoisting coil 6 of the hoisting beam 1 and supports the hoisting beam 1.

[0035] Example 2: Based on Example 1, a shift adjustment component is provided to adaptively fine-tune the assembly position of the hoisting beam 1. The shift adjustment component is located on the side of the hoisting beam 1 near the mounting beam 2. The shift adjustment component includes a wedge-shaped fixing member 11 and two adjustment control cylinders 16. The wedge-shaped fixing member 11 is welded to the upper end of the hoisting beam 1 near the mounting beam 2. Two first connecting ears 12 are symmetrically provided on one side of the wedge-shaped fixing member 11, and two second connecting ears 13 are symmetrically provided on the side of the mounting beam 2 near the wedge-shaped fixing member 11. The two first connecting ears 12 and the two second connecting ears 13 are arranged opposite to each other. 3. A combination connection groove 14 is provided on one side. Push constraint grooves 15 are provided on the opposite side of the combination connection groove 14 of the first connecting ear 12 and the second connecting ear 13. A U-shaped assembly frame 17 is fixed on both sides of the two adjustment control cylinders 16. 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 connecting ear 12 and the second connecting ear 13 respectively. The first connecting ear 12 and the second connecting ear 13 of the hoisting beam 1 and the installation beam 2 are conveniently assembled with the adjustment control cylinder 16 through the combination connection groove 14, and can be easily removed 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 pushes the hoisting beam 1 horizontally, the two push rods 18 of the adjustment control cylinder 16 are respectively inserted into the push constraint groove 15 of the first connecting ear 12 and the second connecting ear 13. When it is necessary to make a fine adjustment to 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 groove 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. Within the push constraint groove 15 of the first connecting ear 12 and the second connecting ear 13, the push constraint groove 15 can restrict the push rod 18 from disengaging 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 hoisting beam 1 can be moved to a different position, and then the mounting beam 2 and the hoisting beam 1 can be fixed. At this time, the adjustment control cylinder 16 can retract appropriately and be removed from the first connecting ear 12 and the second connecting ear 13. Then, a support is welded between the wedge-shaped fixing member 11 and the mounting beam 2 using metal rods, or U-shaped assembly frames 17 are set at both ends of the turnbuckle for support and tension limit in the same way.
