Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] like Figures 1-5 As shown, an embodiment of this application discloses a hook built-in beam, including a lifting beam 1, a plurality of through holes 2 on the surface of the lifting beam 1, and a fixing mechanism at the bottom of the lifting beam 1;

[0027] The fixing mechanism comprises a through plate 3 arranged at the bottom of the hanging beam 1, the through plate 3 and the hanging beam 1 are inserted, the surfaces of the through plate 3 and the hanging beam 1 are provided with threaded holes, the threaded holes are internally threadedly connected with bolts 4, the surface of the through plate 3 is provided with a fixing groove 5, the fixing groove 5 is internally inserted with a hook cross beam 6, the top of the hook cross beam 6 is provided with a hook nut 7, the inside of the hook nut 7 is threadedly connected with a fine thread column 8, one side of the fine thread column 8 is fixedly provided with a double-head hook body 9, the fine thread column 8 is arranged in the through hole 2, one end of the fine thread column 8 penetrates through the hook cross beam 6 and extends to the outside of the hook cross beam 6, one side of the bolt 4 is fixedly provided with an elastic washer 10, and the double-head hook body 9 is made of 42CrMo super high strength steel material.

[0028] It can be seen that, in the above technical scheme, from the installation process, the components are installed in a reasonable and orderly manner with the help of lifting equipment, ensuring accurate positioning, the through plate and the hanging beam are connected by bolts and elastic washers, the elastic washers provide persistent pre-tightening force, making the connection stable, laying a foundation for the installation of subsequent components, the fine thread column and the hook nut are connected by fine thread, compared with ordinary coarse thread, the pitch is small, the number of thread turns is large, the connection is tight, can bear larger axial tension, and has good self-locking property, reduces the risk of vibration loosening, enhances the overall structural reliability, during the lifting operation, the force is sequentially transmitted through the components, the structure design is scientific and reasonable, and the heavy object can be effectively carried. At the same time, the form of arranging the cross beam in the hanging beam, ingeniously uses the internal space, meets the scene that the lifting space is limited but the lifting height is required, ensures that the lifting operation is safely and stably completed, and improves the work efficiency and safety.

[0029] Use process:

[0030] First, determine the installation position of the lifting beam 1. The lifting beam 1 is the main load-bearing structure of the entire hook's internal beam. Multiple through holes 2 are opened on its surface. These through holes provide the position basis for the connection of subsequent components. The hook nut 7 is lifted to the top of the lifting beam 1 by the lifting equipment and placed at a suitable position on the top of the hook crossbeam 6. Then, the through plate 3 is inserted into the lifting beam 1 so that the through plate 3 and the lifting beam 6 fit tightly. After the corresponding threaded holes on the surface of the through plate 3 and the lifting beam 1 are aligned, the through plate 3 is fixed to the bottom of the lifting beam 1 by screwing the bolt 4 into the threaded hole. An elastic washer 10 is fixedly installed on one side of the bolt 4. During the tightening of the bolt 4, the elastic washer 10 undergoes elastic deformation, which can generate continuous pressure to prevent the bolt 4 from loosening due to vibration and other reasons, and ensure the stability of the connection between the through plate 3 and the lifting beam 1. Then, the hook beam 6 is inserted into the fixing groove 5 opened on the surface of the through plate 3 to achieve the initial positioning of the hook beam 6 on the through plate 3. Then, one end of the fine thread post 8 is fixed on the double-headed hook body 9. The fine thread post 8 passes through the hook nut 7 at the top of the hook beam 6. By rotating the hook nut 7, the threaded engagement between the fine thread post 8 and the hook nut 7 allows the double-headed hook body 9 to be adjusted and tightened within a certain range according to the actual lifting requirements. The double-headed hook body 9 and the fine thread post 8 are integrated into one design to improve stability.

[0031] Because the double-headed hook body 9 is made of 42CrMo ultra-high strength steel, this steel has the advantages of high strength, high toughness, and good fatigue resistance. It has high strength and good toughness, good hardenability, and no obvious temper brittleness. It can withstand the huge tensile and impact forces when the hook lifts a 500T load, ensuring the safe use of the hook.

[0032] Next, the hoisting equipment crane connected to the lifting beam 1 is started. The hoisting equipment applies an upward pulling force, which is transmitted sequentially through the lifting beam 1 to the through plate 3, then through the through plate 3 to the hook beam 6, then through the hook beam 6 to the hook nut 7, then through the hook nut 7 to the fine threaded column 8, and finally to the double-headed hook body 9, thereby lifting the object to be lifted. Since the hook internal beam adopts the structure of setting the crossbeam inside the lifting beam, the internal space of the lifting beam is fully utilized to effectively complete the lifting task and ensure that the lifting operation is carried out safely and smoothly.

[0033] Example 2:

[0034] like Figure 5 As shown, this embodiment provides a hook built-in beam, including an anti-detachment mechanism on one side of a double-headed hook body 9. The anti-detachment mechanism includes two rotating rods 11 rotatably disposed on the surface of the double-headed hook body 9. Anti-detachment strips 12 are fixedly disposed on the outside of the two rotating rods 11. A torsion spring 13 is fixedly disposed on one side of the anti-detachment strip 12. The torsion spring 13 is sleeved on the outside of the rotating rod 11, and one end of the torsion spring 13 is connected to the double-headed hook body 9.

[0035] It can be seen that in the above technical scheme, the operator can easily open the anti-off strip to hang the object, and then it is automatically reset, effectively preventing the hoisted object from accidentally falling off during hoisting. This design is simple and practical, greatly enhances the safety of hoisting operation, reduces the risk of accidents, and protects the safety of personnel and equipment without affecting the convenience of operation.

[0036] Use process: after installation, manually rotate the anti-off strip 12 and check its rotation flexibility to ensure that the torsion spring 13 can work normally, so that the anti-off strip 12 can partially block the opening of the double-end hook body 9 in the natural state, preventing the hoisted object from accidentally falling off. The operator overcomes the elastic force of the torsion spring 13, rotates the anti-off strip 12, and fully opens the opening of the double-end hook body 9. The connecting part of the hoisted object is accurately hung into the double-end hook body 9 to ensure firm hanging. Then, the anti-off strip 12 is loosened, and the elastic force of the torsion spring 13 will make the anti-off strip 12 return to the initial position, re-block the opening of the double-end hook body 9, and prevent the object from falling off during hoisting.

[0037] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made in terms of structure, shape, and principle based on the present application should be covered within the protection scope of the present application.
