When the diameter of the ram protrusion 61 of the ram 60 becomes larger than the inner diameter of the retaining end 52 of the ram housing 50 and the ram 60 is pulled out of the upper portion of the ram housing 50, The ram 60 and the ram housing 50 are simultaneously raised so that the ram housing 60 is engaged with the ram housing 50. When the ram housing 60 is moved for hunting or the like, It is possible to move in the raised state, thereby facilitating the movement.

The lower inner diameter of the ram housing 50 is larger than the outer diameter formed by the ram protrusions 61 so that the ram 60 can be drawn out to the lower inner diameter of the ram housing 50, Thereby facilitating the separation, storage, and repair of the housing 50.

The ram protrusions 61 are formed in the longitudinal direction of the ram 60 so as to guide the ram 60 in the inside of the ram housing 60 .

 The ram housing 50 is installed on the guide of the hanger reader 70 so as to be movable up and down. The ram 60 is mounted on the ram housing 50 so as to be movable up and down. the wire cable b connected to the upper portion of the lead master 1 of a) is coupled to the upper portion and is lifted by the winding of the wire cable b to fall freely at a constant height by its own load, ).

The file cap 53 is connected to the lower portion of the ram housing 50 and the upper portion of the file c exposed in the ground is located inside the file cap 53, The cushioning material 54 of high durability is inserted into the upper portion of the pile cap to absorb the striking force of the ram 60, that is, the anti-striking force, while preventing direct contact between the pile c and the ram 60.

The ram 60 is lifted from the inside of the ram housing 50 by the wire cable b and then the ram 60 is lifted up to a heavier weight. The file (c) strikes the file (c), and the file (c) is stuck to the support layer by the impact energy of the ram (60).

A large shock noise is generated when the ram 60 strikes the file P. To reduce the noise, the shock absorber 54 is configured to correspond to the top of the impact point of the file c, And absorbs impact noise generated when the ram 60 falls free and strikes the file c, that is, hovering noise, to thereby shield the hitting noise from being emitted to the outside.

The cushioning material 54 may be any shielding material that absorbs the horseshoe noise and is supported by the supporting device 30 and the hydraulic device 20 in a spaced- It is preferable that each one of the upper and lower brackets 71 is formed to be spaced apart from each other by a predetermined distance.

Therefore, the present invention can prevent the reader from interfering at the time of pile operation and move the pile up to the ground at the time of pile operation, so that the pile can be pushed up to the ground, and the pile is connected to the reader master by a simple device such as a hydraulic device The overall weight of the cramp cranes is reduced, and the hydraulic device uses the hydraulic pressure of the hydraulic device of the crawler crane, so that the overall structure is simple, energy efficiency is good, and the length of the housing can be extended, And the impact energy can be increased.
