[0022] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0023] Example

[0024] Please refer to Figures 1-4 This application provides a lifting device for prefabricated residential components, including: a balance bar 1; two lifting rings 4, disposed on the annular surface of the balance bar 1 and spaced apart along the axial direction of the balance bar 1; wherein the two lifting rings 4 are symmetrically arranged about the middle of the balance bar 1; and a connecting assembly, including a connecting ring 3, a lifting rope 5, and a hook 6, wherein the connecting ring 3 is slidably disposed on the balance bar 1, one end of the lifting rope 5 is connected to the connecting ring 3, and the other end is connected to the hook 6, and the lifting rope 5 and any of the lifting rings 4 are respectively located on opposite sides of the balance bar 1; wherein there are multiple connecting assemblies, which are arranged sequentially along the axial direction of the balance bar 1.

[0025] Existing lifting devices, due to the fixed connection point of the balance bar 1 to the lifting rope 5, cannot flexibly adjust the position of the lifting rope 5 according to different components, greatly limiting their application scenarios, resulting in poor practicality and difficulty in meeting the complex needs of prefabricated building construction. However, the lifting device for prefabricated residential components in this application embodiment, during use, first connects the balance bar 1 to a crane through two lifting rings 4 symmetrically arranged on its annular surface and spaced apart along the axial direction to obtain lifting power. The connecting rings 3 of multiple connecting components can slide on the balance bar 1. According to the shape, size, and center of gravity distribution of the prefabricated component, the sliding connecting rings 3 adjust the position of the lifting rope 5, so that the hook 6 connects to the component. This solution has significant advantages: the sliding connecting rings 3 allow for flexible adjustment of the position of the lifting rope 5, adapting to different components, greatly expanding the application scenarios of the lifting device, improving practicality, better meeting the complex and ever-changing needs of prefabricated building construction, and ensuring safe and efficient construction.

[0026] In a preferred embodiment, the balance bar 1 includes a first rod 102, a second rod 103, a connecting body 101, and a sealing body 104. The first rod 102 and the second rod 103 are arranged parallel to each other and spaced apart, forming an installation gap between them. The connecting body 101 is disposed at the first end of the installation gap and is used to connect the first rod 102 and the second rod 103. The sealing body 104 is detachably disposed at the second end of the installation gap. The lifting ring 4 is disposed on the second rod 103, and any of the connecting rings 3 can be slidably sleeved on the first rod 102.

[0027] In the above embodiment, the connector 101 is disposed at the first end of the installation gap, which serves to connect the first rod 102 and the second rod 103 into one unit, and to seal the port of the installation gap. The sealing body 104 is used to seal the port of the installation gap. By removing the sealing body 104, the number of connecting components can be adjusted, which is practical.

[0028] In a preferred embodiment, one end of the sealing body 104 is rotatably connected to the second rod 103, and the other end is detachably connected to the first rod 102 via a first bolt group.

[0029] In the above embodiment, by removing the first bolt group, the sealing body 104 can be rotated away from the installation gap, and the connecting ring 3 can be removed from the first rod body 102 or the number of connecting rings 3 can be increased.

[0030] Specifically, the sealing body 104 is concave, and both the first rod 102 and the second rod 103 are located within the groove of the concave sealing body 104, with the first rod 102 located at the bottom of the groove. Both the concave sealing body 104 and the first rod 102 are provided with through holes for the first bolt group to pass through.

[0031] In a preferred embodiment, any of the aforementioned connecting rings 3 is provided with a second bolt group;

[0032] The first rod 102 is provided with a plurality of positioning through holes 2, and the plurality of positioning through holes 2 are arranged sequentially at intervals along the axial direction of the first rod 102, and any of the second bolt groups can be engaged with any one of the plurality of positioning through holes 2.

[0033] In the above embodiments, when hoisting different prefabricated components, the connecting ring 3 can be slid to a suitable position according to the shape, size, and center of gravity of the component. Then, the connecting ring 3 is fixed to the first rod body 102 by engaging the second bolt group with the corresponding positioning through hole 2. Compared with a non-adjustable connection structure, this method can more accurately adjust the position of the hoisting rope 5 and hook 6, ensuring that the component is subjected to uniform force during hoisting and avoiding damage to the component or unstable hoisting due to uneven force.

[0034] In a preferred embodiment, a rotating body 9 is provided at the end of the suspension rope 5 away from the hook 6, and the rotating body 9 is rotatably disposed on the connecting ring 3.

[0035] In the above embodiments, when it is necessary to adjust the installation position of the hook 6, this can be easily achieved by using the rotation function of the rotating body 9, without the need to rotate the lifting rope 5. This method is not only simple to operate, but also effectively avoids problems such as entanglement and wear that may be caused by rotating the lifting rope 5, greatly improving the efficiency and safety of adjusting the position of the hook 6, and making the hoisting work smoother and more efficient.

[0036] In a preferred embodiment, the connecting ring 3 is provided with a positioning bolt 8 for positioning the rotating body 9 after it rotates.

[0037] In the above embodiments, when hoisting prefabricated components, the rotating body 9 can rotate flexibly according to actual needs to adjust the position of the hook 6, making the lifting device suitable for hoisting different components. When the rotating body 9 rotates to a suitable angle, the positioning bolt 8 can quickly lock it, preventing the rotating body 9 from rotating arbitrarily during hoisting, ensuring the stability of the hook 6 position, avoiding component swaying and imbalance due to changes in the position of the hook 6, ensuring the safe and stable conduct of hoisting operations, and improving the reliability and practicality of the lifting device in complex hoisting scenarios.

[0038] As a preferred embodiment, the hook 6 is hinged with a limiting piece 7 at the hook opening.

[0039] In the above embodiment, the limiting piece 7 can rotate around the hinge point. After the hook 6 hooks the component, rotating the limiting piece 7 so that it covers the hook opening can effectively prevent the component from accidentally falling out of the hook opening. Especially when encountering shaking or bumps during hoisting, the limiting piece 7 can provide additional protection and ensure the safety of component hoisting.
