[0027] In the description of the embodiments of this application, it should be noted that, unless otherwise specified and limited, the term "connection" should be understood in a broad sense. For example, it can be an electrical connection, or it can be the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meaning of the above terms can be understood according to the specific circumstances.

[0028] It should be noted that the terms "first, second, and third" in the embodiments of the present application are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It is understood that the terms "first, second, and third" can be interchanged to represent a specific order or precedence where permitted. It should be understood that the objects distinguished by "first, second, and third" can be interchanged where appropriate, such that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0029] The embodiment of the present application provides a garage segmented lifting tool, such as Figure 1 As shown, the garage segmented lifting tooling includes:

[0030] The boom 1 is cylindrical and has a groove on the upper portion for installing a wedge-shaped tightening device 3.

[0031] The boom 2, several booms 2 are evenly distributed on the boom 1, which is a stud docking type, such as Figure 2 As shown, its arm span is convex.

[0032] Lifting lug 4 serves as the connection point between the garage section lifting tooling and the crane.

[0033] like Figure 3 As shown, the wedge-type tightening device 3 is composed of relatively constructed wedges, and the wedge tail is provided with a pushing device to facilitate tightening.

[0034] In some embodiments, the material of the boom 1 is steel.

[0035] In some embodiments, the boom 2 has an outward convex arm span design, and its curvature is used to optimize the mechanical distribution during the lifting process.

[0036] In some embodiments, the lifting lug 4 has an anti-slip design to ensure safety during the lifting process.

[0037] In some embodiments, the wedge portion of the wedge-type tightening device 3 is made of aluminum alloy to reduce weight and improve durability.

[0038] In some embodiments, the pushing device of the wedge-type tightening device 3 includes a hydraulic or pneumatic system to achieve a smooth and uniform tightening force.

[0042] In some embodiments, a balancing system is also included for automatically adjusting the balance state of the garage segmented lifting tooling during the lifting process.

[0043] The working principle of the above embodiment is as follows: the vehicle deck segment structure is as follows Figure 4 As shown, after the crane lifts the lifting tooling, it first fixes the boom through the lashing holes on the vehicle deck segments, then starts pre-lifting to put stress on most of the boom, and then pushes the boom tight again through the wedge-shaped tightening device to avoid partial boom stress due to hole opening error.

[0044] Use the boom balance to achieve multi-point lifting, so that the force direction is consistent, reduce the uneven force on the sections to be lifted, and reduce the possibility of deformation;

[0045] The wedge-shaped tightening device is used to pre-load the lifting device before lifting to avoid uneven force caused by the placement of the lifting device, further reducing the possibility of deformation.

[0046] Use the outward-facing boom to avoid obstruction by the garage's segmented structure.

[0047] The use of lifting equipment can reduce or even avoid the deformation of garage sections, saving a lot of subsequent fire adjustment work caused by section deformation.
