Problems solved by technology
Diesel hammer has strong impact force, strong penetrating power, and flexible transition, but the construction noise is large, there is a lot of oily smoke, serious pollution, and the impact force is easy to damage the pile. Especially for piles with large bearing capacity, the construction quality is difficult to control. Personnel have a greater impact
The hydraulic static pile driver has no vibration, low noise, high efficiency and energy saving, and high pile quality; but the machine is heavy and has high requirements on the construction site; Large, the pile end is difficult to penetrate, and the scope of application is limited

The invention relates to a down hole impact type hydraulic static pile driving machine which comprises a machine body platform, a lifting mechanism, a longitudinal movement mechanism and a transverse movement mechanism, wherein the machine body platform is connected with the longitudinal movement mechanism and the transverse movement mechanism through the lifting mechanism and is provided with a cab, a crane, a pile driving table, movable counterweight iron, an electric control system and a hydraulic control system, the pile driving table is provided with a pile driving oil cylinder, the piston rod end of the pile driving oil cylinder is connected with a pile clamping box, the machine body platform is also provided with a tower frame, the top end of the tower frame is connected with a tower head through a rotary support, a hoister is arranged on the tower head, a steel wire rope of the hoister is connected with an impact hammer, the impact hammer has a same medial axis with the pile clamping box, a connecting oil cylinder is also arranged between the tower frame and the tower head, a cylinder barrel of the connecting oil cylinder is articulated to the tower frame, a piston rod of the connecting oil cylinder is articulated to the tower head, and the connecting oil cylinder is connected with the hydraulic control system on the machine body platform through an oil pipe. The invention has the advantages of high pile driving quality and wider application range and can lightly penetrate through a dense hard formation.
Description
technical field [0001] The invention relates to a hydraulic static pile driver, in particular to a down-the-hole impact hydraulic static pile driver. Background technique [0002] At present, there are two main methods for forming prefabricated pile foundations: one is to hit the top of the prefabricated pile with a diesel hammer, and drive the prefabricated pile into the foundation to form a pile; the other is to use a hydraulic static pile driver to drive the prefabricated pile into the foundation. Press into the foundation to form a pile. Diesel hammer has strong impact force, strong penetrating power, and flexible transition, but the construction noise is large, there is a lot of oily smoke, serious pollution, and the impact force is easy to damage the pile. Especially for piles with large bearing capacity, the construction quality is difficult to control. Personnel are greatly affected. The hydraulic static pile driver has no vibration, low noise, high efficiency and ...
