Description

Technical Field

[0001] The utility model relates to the technical field of pile drivers, and more specifically, to a pressure head of a vibration pile driver. Background Art

[0002] In the construction of large-scale ditch photovoltaic power stations, pile drivers are mainly used to fix photovoltaic brackets. As an important structure for supporting photovoltaic panels, the stability and safety of photovoltaic brackets directly affect the operating efficiency and service life of the entire photovoltaic power station. Therefore, the selection and use of pile drivers are crucial. Among the existing disclosed technologies, the patent publication number CN215562593U discloses a pile driver pressure head, which uses a special drill bit structure in combination with a leg frame coupled pad box to squeeze the slag cut out during the drilling process to the surrounding of the pile hole, and no longer discharges the slag upward. In addition, due to the use of the coupled pad box, it plays a vertical guiding role during drilling, avoids the bulge of the empty ground, eliminates the slag, avoids the pollution caused by the transportation of slag, and reduces the construction cost. However, the pressure head has the following defects;

[0003] When the pressure head is used on a vibrating pile driver, piles need to be provided during the construction of a large-area ditch photovoltaic power station to complete the piling operation. Although the pressure head can be used to position the outer wall of the bottom end of the pile body during the piling process, the pile body is relatively long. Once the tilting force is generated at the top of the pile body, the pile body and the pressure head will be tilted, impacted and worn, which is very easy to damage the pressure head and the pile body of the ditch photovoltaic power station. For this purpose, a pressure head is provided. Utility Model Content
