Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic construction, in particular to a pile foundation casting device for photovoltaic construction. Background Art

[0002] Photovoltaic pile foundation is one of the important devices to support and stabilize photovoltaic facilities and equipment. According to the production method of photovoltaic pile foundation, it can be divided into prefabricated photovoltaic pile foundation and cast-in-place photovoltaic pile foundation.

[0003] In the prior art, for example, the pile foundation casting device for photovoltaic construction disclosed in publication number CN217974386U records: The utility model is provided with spiral conveying blades on the outer wall of the rotating tube, and a rotating rod is provided inside the rotating tube. One end of the rotating rod is connected to the vibrating rod through a flexible shaft. The rotating tube and the rotating rod are driven by the same driving assembly. While being able to stably convey concrete, it can also automatically vibrate the concrete at the conveying position after the conveying is completed, thereby improving the quality and efficiency of casting.

[0004] In actual use, after the cement is poured, a vibrating rod is placed in the cement for vibration. When the cement is vibrated to expel bubbles, the position of the vibrating rod needs to be constantly moved to fully expel the bubbles in the poured cement. However, the vibrating rod of the above-mentioned device is connected to the entire device. Moving the vibrating rod requires moving the entire device, which is troublesome to operate and inconvenient to move the device. In addition, when the device is pouring, there is generally a pipe to limit the pouring range. The pipe has a certain height. The above-mentioned device can only adjust the direction through the universal wheel but cannot adjust the height. In addition, the device is prone to shaking during pouring and cement vibration, which is inconvenient for pouring and cement vibration operations. Utility Model Content
