[0021] Such as Figures 1 to 2As shown, the utility model preferably provides a steel reinforcement cage hoisting device, which includes a suspension assembly 1, an upper distribution beam 2 and a lower distribution beam 3; the suspension assembly 1 is arranged above the upper distribution beam 2, one end of the suspension assembly 1 is connected to a crane, and the other end is connected to the upper distribution beam 2; the upper distribution beam 2 includes an upper beam body 21 and a plurality of extension parts 22, the plurality of extension parts 22 are arranged at both ends of the upper beam body 21 at intervals, and each extension part 22 extends along a first direction for connecting the lower distribution beam 3; the number of the lower distribution beams 3 is multiple, the multiple lower distribution beams 3 are all arranged below the upper beam body 21, and each lower distribution beam 3 includes a lower beam body 31 and a pin shaft part 32, one end of the lower beam body 31 is connected to the extension part 22, the pin shaft part 32 is arranged between the lower beam body 31 and the extension part 22, the pin shaft part 32 penetrates through the lower beam body 31 and the extension part 22 along a second direction, and the lower beam body 31 can rotate along the axial direction of the pin shaft part 32.

[0022] Based on the above technical features, through the setting of the suspension assembly 1, the suspension assembly 1 serves as the starting point of the entire hoisting system. The suspension assembly 1 firmly connects the crane and the upper distribution beam 2 to ensure the safety and stability of the hoisting process. Its design needs to consider the load-bearing capacity and stability to cope with the weight of the steel reinforcement cage and the dynamic load during the hoisting process; through the setting of the upper distribution beam 2, the upper distribution beam 2 serves as the main load-bearing component of the steel reinforcement cage hoisting force. The upper beam body 21 has high strength and high stiffness and can resist bending and deformation during the hoisting process. The lower distribution beam 3 includes the upper beam body 21 and the extension parts 22. The extension parts 22 are arranged at both ends of the upper beam body 21 and extend along the first direction for connecting the lower distribution beam 3 to ensure the firmness and flexibility of the connection between the upper distribution beam 2 and the lower distribution beam 3; through the setting of the lower distribution beam 3, the lower distribution beam 3 serves as the component that directly contacts the steel reinforcement cage in the entire hoisting device. It directly bears the weight of the steel reinforcement cage and realizes the hoisting of the steel reinforcement cage through the connection with the extension part 22. The lower distribution beam 3 includes a lower beam body 31 and a pin shaft part 32. The pin shaft part 32 is the key connection component between the lower beam body 31 and the extension part 22, and it allows the lower beam body 31 to rotate around the pin shaft part 32 along the second direction. This design can compensate for the small deviations during the hoisting process and improve the positioning accuracy of the steel reinforcement cage. At the same time, the pin shaft part 32 also needs to have sufficient strength and wear resistance to withstand the load and friction during long-term use. At the same time, it also improves the flexibility and accuracy of the hoisting process, enabling the steel reinforcement cage to reach the predetermined position more accurately.

[0023] As some embodiments of the utility model, such as Figure 1As shown in the figure, the suspension assembly 1 includes a suspension rod 11 and a support sleeve 12. The suspension rod 11 is arranged in the middle of the upper beam body 21, and the suspension rod 11 penetrates the upper beam body 21 in the vertical direction. The support sleeve 12 is sleeved on the outer periphery of the suspension rod 11. The support sleeve 12 is located above the upper beam body 21 and is used to connect the crane. Through the arrangement of the suspension rod 11 and the support sleeve 12, the suspension rod 11 is arranged in the middle of the upper beam body 21, which can ensure that the force transmitted from above can be evenly distributed to the entire upper beam body 21, reduce stress concentration, and enhance the stability of the structure. At the same time, the suspension rod 11, as the main component connecting the upper beam body 21 and the support sleeve 12, is responsible for directly conducting the force from above to the lower upper beam body 21 and is an important support structure of the suspension assembly 1. The main function of the support sleeve 12 is to connect the crane to ensure that they can be safely and stably suspended in the air. By adjusting the position of the support sleeve 12 on the suspension rod 11, the height and position of the suspended equipment can be finely adjusted to meet different operation requirements. At the same time, the stability of the connection between the suspension assembly 1 and the crane is effectively improved.

[0024] As some embodiments of the present utility model, as Figure 1 shown in the figure, the bottom end of the support sleeve 12 is connected to the top end of the upper beam body 21, and the outer diameter of the outer edge of the support sleeve 12 is larger than the outer diameter of the suspension rod 11. The close connection between the support sleeve 12 and the upper beam body 21 and the larger outer diameter of the support sleeve 12 are both for improving the stability, safety and reliability of the connection between the suspension assembly 1 and the crane.

[0025] As some embodiments of the present utility model, as Figure 1 shown in the figure, the suspension assembly 1 includes a first fastener 13. The first fastener 13 is located at the top end of the suspension rod 11, and the fixed end of the first fastener 13 abuts against the top end of the support sleeve 12 for fixing the support sleeve 12. The main function of the first fastener 13 is to ensure that the support sleeve 12 is firmly fixed on the suspension rod 11. Through the close abutment of its fixed end with the top end of the support sleeve 12, the first fastener 13 effectively prevents the support sleeve 12 from moving or falling off in the vertical direction, thus ensuring the overall stability of the suspension assembly 1.

[0026] As some embodiments of the present utility model, as Figure 1 shown in the figure, the suspension assembly 1 further includes a second fastener 14. The second fastener 14 is located at the bottom end of the suspension rod 11, and the fixed end of the second fastener 14 abuts against the bottom end of the upper beam body 21 for fixing the upper beam body 21. The setting of the second fastener 14 further improves the overall rigidity and strength of the suspension assembly 1. It not only restricts the movement of the upper beam body 21 in the vertical direction but also can restrict its offset in the horizontal direction. In addition, the second fastener 14 also shares part of the weight and load transmitted from the support sleeve 12 and the crane, reduces the stress on other parts of the upper beam body 21, and helps to extend the service life of the entire suspension assembly 1.

[0027] As some embodiments of the present utility model, Figure 1 As shown, the upper distribution beam 2 also includes a stiffening web 23, which is arranged at the top of the upper beam body 21, and one end of the stiffening web 23 is connected to the extension portion 22. The stiffening web 23 is arranged at the top of the upper beam body 21, and its main function is to enhance the lateral rigidity of the upper distribution beam 2. When it is subjected to lateral loads, the stiffening web 23 can resist bending deformation and maintain the stability of the structure. By setting the stiffening web 23, the load borne by the upper beam body 21 can be more evenly distributed to the entire upper distribution beam 2, reducing the local stress concentration phenomenon, thereby improving the overall bearing capacity and durability of the upper distribution beam 2.

[0028] As some embodiments of the present utility model, Figure 2 As shown, a hoisting cavity for arranging the suspension wire rope is provided inside the lower beam body 31. The hoisting cavity provides a safe operating environment for the suspension wire rope. When the wire rope needs to be replaced or inspected, it is only necessary to open the inspection port of the hoisting cavity without disassembling the entire lower distribution beam 3.

[0029] As some embodiments of the present utility model, Figure 2 As shown, a plurality of stiffening rods 33 are arranged in the hoisting cavity, and each stiffening rod 33 penetrates the hoisting cavity along the second direction to improve stability. By setting the stiffening rods 33, the stiffness of the hoisting cavity in the second direction can be significantly enhanced, and deformation caused by uneven force or external factors during the hoisting process can be prevented, thereby ensuring the stability and safety of the hoisting operation. The presence of the stiffening rods 33 makes the hoisting cavity more stable when bearing heavy loads, improves the bearing capacity of the entire lower distribution beam 3, and enables the hoisting operation of the device to cope with more complex working conditions and heavier loads.

[0030] In summary, compared with the prior art, the cage hoisting device provided by the embodiment of the present utility model has the following beneficial effects: 1) The suspension assembly 1, as the starting point of the entire hoisting system, firmly connects the crane and the upper distribution beam 2, ensuring the safety and stability of the hoisting process. Its design needs to consider the load-bearing capacity and stability to cope with the weight of the steel cage and the dynamic load during the hoisting process; 2) The upper distribution beam 2, as the main load-bearing component of the steel cage hoisting force, the upper beam body 21 has high strength and high stiffness, and can resist bending and deformation during the hoisting process. The lower distribution beam 3 includes the upper beam body 21 and the extension part 22. The extension part 22 is arranged at both ends of the upper beam body 21 and extends along the first direction, and is used to connect the lower distribution beam 3 to ensure the firmness and flexibility of the connection between the upper distribution beam 2 and the lower distribution beam 3; 3) The lower distribution beam 3, as the component of the entire hoisting device that directly contacts the steel cage, directly bears the weight of the steel cage and realizes the hoisting of the steel cage through the connection with the extension part 22. The lower distribution beam 3 includes the lower beam body 31 and the pin shaft part 32. The pin shaft part 32 is the key connection component between the lower beam body 31 and the extension part 22, and it allows the lower beam body 31 to rotate around the pin shaft part 32 along the second direction. This design can compensate for the slight deviation during the hoisting process and improve the positioning accuracy of the steel cage. At the same time, the pin shaft part 32 also needs to have sufficient strength and wear resistance to withstand the load and friction during long-term use. At the same time, it also improves the flexibility and accuracy of the hoisting process, enabling the steel cage to reach the predetermined position more accurately. The present utility model effectively solves the problem in the prior art that during the suspension process of the steel cage, the rotation direction of the steel cage cannot be adjusted, resulting in difficulties in positioning and low accuracy when placing the steel cage.

[0031] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and substitutions can still be made, and these improvements and substitutions should also be regarded as the protection scope of the present utility model.
