BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibro hammer device, and more particularly, to a vibro hammer used for driving operations such as a sheet pile during the foundation work of a construction site.

In general, in order to build all structures such as concrete buildings, bridges, soil barriers, and various dams on the ground, it is necessary to carry out foundation works for laying concrete piles, steel pipe piles, H-beams, etc. so that the ground can withstand the weight of the structure. .

Construction of such piles is very important in constructing structures and buildings.

In particular, in the case of soft ground, the foundation work must be carried out by fixing piles to rock in the basement layer below the ground surface.

In this basic construction, the work of driving the pile into the ground is called driving work.

Normally, foundation foundations such as bridges, harbors, and buildings use pre-built piles such as RC piles, PC piles, and steel pipe piles, which are installed after hammering or drilling with augers. Except when the environmental impact is to be taken into consideration, the driving type construction is mainly applied in terms of economy and constructability.

In general, rudders are used to attach steel pipe piles or concrete piles with drop hammers, diesel hammers, vibro hammers, etc. by attaching accessories to hitting piles on cranes. It is mainly used for driving the beam.

Recent driving operations mainly use a method of vibrating the chuck in the driving direction, that is, perpendicular to the pile by operating the vibrator while the pile is fixed to the chuck.

The vibration of the pile reduces friction between the pile and the ground, so that smooth driving can be performed.

Such a driving operation is performed by drilling a pile in the ground, infiltrating a pile into the ground, and then hitting or vibrating the pile with a vibrator hammer or the like.

However, the conventional driving operation has various problems in terms of workability and efficiency.

For example, a hole is drilled into a file such as an H-beam, and a worker manually connects the chain to a vibratory hammer, and then chains the file, since the file is to be vertically lifted and entered into the file hole. There is a problem that the work of the work is very inefficient, and the work takes a lot of work time as a whole.

In addition, since the file continuously shakes even when the file is vertically lifted into the file hole, there is a problem that may cause danger to the safety of the worker, such as assisting the operator to precisely adjust the file to the file hole position.

In addition, the conventional vibro hammer can work only one pile shape, that is, the efficiency of the work is required because the work must be done using different types of vibrating hammer according to the shape of the pile pile. There is a problem that falls a lot.
