Its structural components include: a rectangular frame: welded from H-beams, equipped with multiple hooks and steel shackles for lifting; the hooks can be connected to a crane via wire ropes, and the steel shackles are used to connect to the fixing pieces; a fixing plate: its upper and lower ends are detachably fixed to the top and bottom beams of the module unit, respectively; and a fixing piece: fixed to the upper end of the fixing plate, with a mounting hole at its upper end for connecting to the steel shackles.

[0003] In existing technologies, lifting devices are not suitable for occasions that require frequent adjustments to the lifting point position or the bearing of asymmetrical heavy objects, such as lifting irregularly shaped parts in shipyards or handling goods with an unstable center of gravity in logistics scenarios. Consequently, the lifting point position cannot be adjusted, making them unsuitable for lifting flexible unbalanced modules. Therefore, we have made improvements and proposed a flexible unbalanced force-bearing module lifting device made of H-beam welded steel. Summary of the Invention

[0029] like Figure 1-6 As shown, this embodiment proposes a flexible unbalanced force-bearing module lifting device for H-beam welded steel, including a crossbeam 1 and a lifting buckle 2. An adjusting seat 3 is provided on the outer side of the crossbeam 1. Connecting ear plates 4 are provided at both ends of the adjusting seat 3. A lifting chain 5 is provided between the connecting ear plates 4 and the lifting buckle 2. A first hook 6 is provided at both ends of the lifting chain 5. A second hook 7 is provided at the bottom of the adjusting seat 3. An adjusting component 8 is provided between the adjusting seat 3 and the crossbeam 1.

[0030] The adjustment assembly 8 includes a drive box 81 and a support frame 86 fixed to one side of the adjustment seat 3, a drive motor 82 installed at the bottom of the drive box 81, an adapter slot 83 inside the drive box 81, a gear 84 at the output end of the drive motor 82, a toothed groove 85 and a positioning hole 810 on the outer side of the crossbeam 1, a positioning electric telescopic rod 87 installed on one side of the support frame 86, a positioning pin 88 connected to the output end of the positioning electric telescopic rod 87, and an infrared sensor 89 installed at the end of the positioning pin 88.

[0031] There are two sets of adjusting seats 3, which are symmetrically distributed. The adjusting seats 3 are connected to the crossbeam 1 through the adjusting assembly 8. The adjusting seats 3 are installed with the connecting ear plate 4 through bolts, which facilitates the position adjustment of the adjusting seats 3. This makes them suitable for hoisting irregularly shaped parts in shipyards or handling goods with an unstable center of gravity in logistics scenarios.

[0032] The connecting lug 4 and the lifting buckle 2 are connected by the lifting chain 5 and the first lifting hook 6, and the second lifting hook 7 is movably connected to the connecting lug 4, so that the goods can be lifted.

[0033] The drive motor 82 is connected to the drive box 81 by bolts. The adapter groove 83 passes through the middle of the adjustment seat 3. The output end of the drive motor 82 is fixedly connected to the gear 84. The gear 84 meshes with the tooth groove 85. The number of tooth grooves 85 is several sets and they are arranged in an array, which is conducive to adjusting the position of the adjustment seat 3.

[0034] The positioning electric telescopic rod 87 is connected to the support frame 86 by bolts. The output end of the positioning electric telescopic rod 87 is fixedly connected to the positioning pin 88. The end of the positioning pin 88 is provided with an installation groove that matches the infrared sensor 89. The positioning hole 810 passes through the middle of the crossbeam 1 and the adjusting seat 3, which is conducive to positioning after the position of the adjusting seat 3 is adjusted.

[0035] In summary, the working principle of this utility model is as follows:

[0036] When in use, when hoisting irregularly shaped parts or handling goods with an unstable center of gravity in logistics scenarios, the position of the adjusting seat 3 can be adjusted by adjusting the adjusting component 8, thereby adjusting the position of the second hook 7, so that the lifting point can be adjusted to meet the hoisting requirements of the goods. At the same time, the modular connection between the adjusting seat 3 and the crossbeam 1 can be freely disassembled, which is suitable for hoisting items with uneven flexibility.

[0037] It should be noted that, by adjusting the setting of component 8, during the adjustment of the position of the adjusting seat 3, the drive motor 82 is started under the support of the drive box 81, so that the output end of the drive motor 82 drives the gear 84 to rotate along the inside of the adapter groove 83, and at the same time meshes with the tooth groove 85, thereby driving the adjusting seat 3 to adjust its position. After adjusting to the appropriate position, the infrared sensor 89 detects whether the positioning hole 810 is aligned with the positioning pin 88, thereby controlling the output end of the positioning electric telescopic rod 87 to drive the positioning pin 88 to insert along the inside of the positioning hole 810, thereby positioning the adjusting seat 3 and the crossbeam 1, satisfying the position adjustment of the second hook 7, and thus adjusting the lifting point, which is suitable for the lifting operation of flexible and uneven items.

[0038] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
