Description

Technical Field

[0001] The utility model relates to the technical field of static pile drivers, in particular to a universal jaw clamp for static pile drivers. Background Art

[0002] A static pile driver is a machine for pile foundation construction. The static pile driver includes a pile clamping box, in which multiple sets of pile clamping assemblies are installed. The multiple sets of pile clamping assemblies are distributed in a circle on the pile clamping box. The piles are installed in the space surrounded by the multiple sets of pile clamping assemblies. After the piles are clamped by the pile clamping assemblies, the prefabricated piles are pressed into the soil through the pile pressing mechanism of the static pile driver with the reaction force provided by the deadweight of the pile driver and the counterweight on the frame. The pile columns of the static pile driver are generally cylindrical and square in shape. Therefore, the universal jaw clamp of the static pile driver needs to consider the fixation of these two different shapes of pile columns.

[0003] However, the universal jaw clamps of some static pile drivers currently available generally clamp and fix the pile by tightening bolts, and cannot quickly clamp and fix both sides of the pile at the same time, which is time-consuming and labor-intensive. At the same time, when it is necessary to fix the square pile, the clamp cannot be quickly replaced, which has low practicality and reduces the efficiency of the project. To this end, we propose a universal jaw clamp for a static pile driver to solve the above problems. Utility Model Content
