Modular vibratory pile driver system

Abstract

A modular side grip vibratory pile driver system having a housing, a vibratory gear case and a pair of jaws adapted to grip a variety of pile profiles. The housing is rotatably connected to a construction machine such that the jaws can be moved from a position wherein the jaws are oriented vertically and spaced apart horizontally to a position wherein the jaws are oriented horizontally and spaced apart vertically. A plurality of sets of gripping assemblies having different gripping profiles are interchangeably connected to the jaws.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit under Title 35, U.S.C. §119(e) of U.S. Provisional Application Ser. No. 60 / 943,979, entitled MODULAR VIBRATORY PILE DRIVER, filed on Jun. 14, 2007.BACKGROUND[0002]1. Field of the Disclosure[0003]The present disclosure relates to pile driving equipment. More particularly, the present disclosure relates to a modular vibratory side grip pile driver system and method for assembly.[0004]2. Description of the Related Art[0005]Vibratory pile drivers are used in a plurality of applications to drive pile, such as sheet pile, pipes, I-beams, H-beams, and poles, for example, into the ground. The pile driver may be mounted on an excavator and include articulating arms and side-gripping jaws to facilitate the pile driving process.[0006]Current side grip vibratory pile drivers have the disadvantage that they are designed for driving only one type of pile. Therefore, if it is desired to switch from driving sheet pile ...

AI Technical Summary

Benefits of technology

[0008]Advantageously, the modular vibratory pile driver system eliminates the need to obtain a plurality of pile drivers matching the types of pile to be driven. Instead, the modular vibratory pile driver uses the same housing and gear case for all types of pile and utilizes modular sets of gripping assemblies to facilitate driving different types of pile, thereby reducing costs and saving time. Further, the modular vibratory pile drivers of the present disclosure facilitate centering of the pile with the pile driver, thereby enhancing the efficiency of energy transfer to the pile and reducing the stress on the gear case of the pile driver. Moreover, the modular vibratory pile driver facilitates straight driving of the pile because the centerline of the pile matches the centerline provided by the selected modular gripping assembly set.

Problems solved by technology

Current side grip vibratory pile drivers have the disadvantage that they are designed for driving only one type of pile.

This leads to significant increased cost at a job site and requires that the construction company inventory more than type of pile driver for use at its various job sites.
