[0002] An assembled building is to directly transport the precast components prefabricated in a factory to the construction site for assembly. This is one step further in protecting the urban environment compared to the previous construction methods. However, the handling of precast components during the production process of concrete precast components is a relatively large problem.

[0003] For example, a "precast component transfer device" disclosed in a Chinese patent document, with the publication number CN210258445U, includes a support body. The support body includes a hollow support surface. One side of the support surface is provided with a push rod extending out of the support surface. Below one side of the push rod is provided a support leg fixedly connected to the support surface. The other side of the support surface opposite to the push rod is connected to a load-carrying surface through a first hinge. The load-carrying surface can rotate around the support surface relative to the other side of the push rod through the first hinge. The support body is provided with a fixing body on one side of the push rod. The fixing body is connected to the support surface through a second hinge. And the fixing body is fixedly connected to the support body through a spring below the second hinge. A clamping block is provided above the fixing body. The clamping block can be engaged with a clamping groove provided on the load-carrying surface to fix the load-carrying surface. A rolling device is further included below the support body. This device can horizontally transfer and transport the vertically erected precast components, ensuring the safety of transportation.

[0004] Regarding the above related technologies, the inventor found the following defects: 1. The load-bearing capacity is limited, and it does not have an effective separation between the stacked precast components. There will be a certain extrusion force between the components due to their own weight, and the lower precast components are extremely easy to be damaged; 2. Usually, manual handling or transfer is adopted, which is inconvenient for handling and transfer, has low transportation efficiency, and poor stability. Summary of the Utility Model
