Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of transport and transfer devices, and in particular relates to a prefabricated stair transport and transfer device. Background Art
[0002] Prefabricated stairs are divided into landings, stair beams, and flight sections. These are prefabricated in a factory or on-site before being transported to the construction site for assembly. They are a type of prefabricated building component characterized by standardized production and installation.
[0003] Most existing prefabricated stairs are transported by placing M-shaped wooden boards between multiple prefabricated stairs. When the stairs need to be transported, the forklift only needs to be manually driven to insert the fork rod into the M-shaped wooden board, and then move it upward to abut the bottom of the M-shaped wooden board for transportation. However, this structure makes the driver's driving skills very demanding during the transportation process. The fork rod needs to be accurately aligned with the slot in the M-shaped wooden board. If it is not aligned correctly, the driver needs to repeatedly adjust it back and forth, which seriously affects the transportation efficiency. At the same time, when the driver uses a forklift for transportation, the prefabricated stairs are prone to collision and damage during transportation due to factors such as the instability of the transport vehicle, improper operation during loading and unloading, or uneven transportation roads, resulting in the prefabricated stairs being broken or deformed. Summary of the Invention
[0004] The purpose of the present invention is to propose a prefabricated stair transporting device to solve the problem that the transportation of existing prefabricated stairs is very demanding on the driver's driving skills and easily affects the transportation efficiency. At the same time, when the driver uses a forklift to transport the prefabricated stairs, it is easy for the prefabricated stairs to be collided and damaged during transportation due to factors such as the instability of the transport vehicle, improper operation during loading and unloading, or uneven transportation roads, resulting in the stairs being broken or deformed.
