Description

Technical Field

[0001] The utility model relates to the technical field of transportation devices, in particular to a convenient transportation device for prefabricated piers used in infrastructure. Background Art

[0002] The application number is 202221352180.6. It proposes a prefabricated pier for the infrastructure of a rooftop distributed photovoltaic project: During the infrastructure construction of a rooftop distributed photovoltaic project, the prefabricated piers need to be transferred and dispersed to various installation points on the roof. Due to the small operating area and limited bearing capacity of the roof, it is impossible to rely on mechanical equipment for transportation, and the prefabricated piers can only be transported manually. The prefabricated piers are cylindrical, each weighing about 150 kilograms. They are generally transported by rolling. However, some factory roofs are equipped with grounding grids, expansion joints and other building accessories, which are not convenient for rolling the piers. At the same time, manual transportation is more difficult. The design of transportation wheels is used to cooperate with movable rods and support frames to support the support rods. At the same time, it is matched with hooks to drive the piers to move upward through the principle of leverage and leave the ground, avoiding the restrictions of obstacles in some places, resulting in limited equipment use, so as to achieve the effect of facilitating the transportation of piers, improve the transportation efficiency of piers, and reduce the labor intensity of workers.

[0003] However, during use of the above-mentioned device, since the piers are not limited after being suspended, the piers may shake and hit the transportation device during transportation, thereby damaging the transportation device. In addition, during transportation, the staff must always maintain a downward pressure, which increases the transportation intensity.

[0004] Therefore, in response to the above problems, we propose a convenient transportation device for prefabricated piers for infrastructure. Utility Model Content
