[0029] In view of the aforementioned problems, the traditional hoisting devices in the prior art have relatively simple structures, low strength, and heavy overall structure and shear wall weight, which makes them inconvenient to move. Therefore, this utility model proposes a steel cage hoisting device.

[0030] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] This embodiment discloses a steel cage hoisting device. Figure 1 The entire three-dimensional structure of the steel cage hoisting device is shown from a first-person perspective. Figure 2 The entire three-dimensional structure of the steel cage hoisting device is shown from a first-person perspective.

[0032] Please refer to Figure 1 and Figure 2The rebar cage hoisting device of this utility model includes: a lifting beam 1, an upper lifting ring 2 disposed on the upper side of the lifting beam 1, and several lower lifting rings 3 disposed on the lower side of the lifting beam 1; wherein, the lifting beam 1 includes: a first telescopic beam 11 and a second telescopic beam 12; wherein, the upper lifting rings 2 are disposed at both ends of the lifting beam 1, and the second telescopic beams 12 pass through the first telescopic beams 11. By adjusting the length of the second telescopic beams 12 passing through the first telescopic beams 11, it is possible to flexibly handle rebar cages of different sizes and weights, without the need for frequent changes of lifting tools, thus reducing construction costs and improving work efficiency. Connectors are provided on the upper lifting rings 2 to connect the upper lifting rings 2 to the crane. The connectors ensure a firm connection and are easy to operate. The connectors are generally made of high-strength materials and can withstand huge tensile forces, effectively avoiding the risk of breakage that may occur during hoisting. The lower lifting rings 3 are used to hook the rebar cage. Multiple lower lifting rings 3 ensure that multiple points of force are applied during hoisting, preventing deformation or damage to the hoisting device caused by a single point of force.

[0033] Furthermore, a plurality of first fixing holes 111 are provided on the first telescopic beam 11, and a second fixing hole 121 matching the first fixing holes 111 is provided on the second telescopic beam 12; fixing bolts are inserted into the first fixing holes 111 and the second fixing holes 121. In a specific embodiment, the length of the lifting beam 1 can be adjusted according to actual needs, enhancing the flexibility and applicability of the lifting beam. By adjusting the relative position between the first fixing holes 111 and the second fixing holes 121 and locking them with fixing bolts, the total length of the lifting beam can be precisely controlled, thereby meeting the needs under different working conditions.

[0034] Furthermore, both the first telescopic beam 11 and the second telescopic beam 12 are 5m long I-beams. I-beams are characterized by high strength, light weight, and strong bending resistance. Using I-beams as the main material for the telescopic beams in the suspension beam structure ensures that the beams maintain sufficient rigidity and stability even under heavy loads. At the same time, the cross-sectional shape of the I-beams also helps to reduce the overall weight of the suspension beams, lowering transportation and installation costs.

[0035] Furthermore, the fixing bolts are steel bolts. Steel bolts have high strength and corrosion resistance, and can withstand large tensile and shear forces. Using steel bolts as fixing bolts in the first fixing hole 111 and the second fixing hole 121 ensures a firm and reliable connection between the telescopic beams, preventing loosening or falling off during hoisting. In addition, steel bolts are easy to install and disassemble, facilitating the maintenance and upkeep of the lifting beams.

[0036] Furthermore, the lower lifting rings 3 are evenly distributed at the lower ends of the first telescopic beam 11 and the second telescopic beam 12. As a key component connecting the lifting beams and the reinforcing cage, the arrangement and quantity of the lower lifting rings 3 directly affect the lifting effect and safety of the reinforcing cage. By evenly distributing the lower lifting rings 3 at the lower ends of the telescopic beams, it can be ensured that the reinforcing cage is subjected to uniform force during lifting, avoiding localized overload or deformation. Simultaneously, the number of lower lifting rings 3 should also be rationally configured according to the weight and dimensions of the reinforcing cage to ensure the safety and stability of the lifting process.

[0037] Furthermore, the spacing between the first fixing holes is the same as the spacing between the second fixing holes; the spacing between the first fixing holes 111 is 0.4–0.6 m; the spacing between the second fixing holes 121 is 0.4–0.6 m. In a specific embodiment, the spacing between the first fixing holes 111 and the spacing between the second fixing holes 121 are both chosen to be 0.5 m. By adjusting the spacing between the first fixing holes 111 and the second fixing holes 121, the length of the lifting beam can be finely adjusted, making the adjustment between the telescopic beams more precise and flexible, thereby meeting more stringent lifting requirements. In addition, the uniform distribution of the fixing holes also helps to improve the overall strength and stability of the lifting beam, ensuring that damage caused by excessive local stress will not occur during the lifting process.

[0038] Furthermore, the spacing between the lower lifting rings 3 is 1.4–1.6 m. In a specific embodiment, the spacing between the lower lifting rings 3 is generally 1.5 m. The spacing between the lower lifting rings 3 needs to take into account the size and weight of the reinforcing cage and the stress conditions during the lifting process. A reasonable spacing ensures the stability of the reinforcing cage. Simultaneously, the spacing between the lower lifting rings 3 should also match the lifting capacity of the crane to ensure the safety and efficiency of the lifting process.

[0039] Furthermore, the upper lifting ring 2 and the lower lifting ring 3 are welded to the beam body 1 of the lifting beam. Welding, as a common connection method, is characterized by its strong connection, low cost, and ease of operation. In the lifting beam structure, using welding to fix the upper lifting ring 2 and the lower lifting ring 3 to the telescopic beam ensures the strength and stability of the connection. At the same time, welding can also prevent the connection from loosening or falling off, thereby improving the overall safety and reliability of the lifting beam.

[0040] Furthermore, both the upper lifting ring 2 and the lower lifting ring 3 are made of steel. Steel lifting rings have high strength and corrosion resistance, and can withstand large tensile and shear forces. As connecting components in the lifting beam structure, they ensure safety and stability during the lifting process. In addition, steel lifting rings are easy to process and customize, and their shape and size can be adjusted according to actual needs.

[0041] Furthermore, the connecting component is a steel wire rope. Steel wire rope is characterized by high strength, good flexibility, and strong wear resistance. Using steel wire rope as the connecting component ensures a firm and reliable connection between the crane and the hoist. At the same time, the flexibility of the steel wire rope makes the hoisting process more flexible and convenient. In addition, steel wire rope is easy to maintain and replace, reducing hoisting and maintenance costs. Moreover, by adjusting the length of the steel wire rope, the balance of the lifting beam 1 can be ensured, preventing the lifting beam 1 from tilting due to excessive length at one end of the steel wire rope, thus ensuring the stability of the hoisting process.

[0042] In summary, when hoisting a reinforcing cage, first adjust the lifting beam 1 to a suitable length, then use fixing bolts to fix the first telescopic beam 11 and the second telescopic beam 12. Then, according to the state of the reinforcing cage, weld the lower lifting ring 3 to the lower end of the lifting beam 1. Use a crane to lift the reinforcing cage, and after the lower lifting ring 3 is stable, fix the reinforcing cage on the lower lifting ring 3. Then fix the upper lifting ring 2 with the connector, connect the connector to the crane, and further fix the connector to the middle of the lifting beam 1 to further fix the lifting beam 1, making the lifting beam 1 more stable during the hoisting process. This hoisting device has a simple structure, reasonable design, and low cost, and realizes efficient, safe, and stable lifting and transportation of reinforcing cages.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
