Description

파일 그립핑 기능을 가지는 진동식 항타Vibratory driving with pile gripping function
본 발명은 파일 그립핑 기능을 가지는 진동식 항타기에 관한 것으로서, 보다 상세하게는 파일척에 의해 파일의 척킹을 가능하도록 할 뿐만 아니라, 파일그립퍼에 의해 파일의 그립핑을 가능하도록 하고, 이로 인해 파일의 직접적인 항타와 별도의 항타기를 이용한 간접적인 항타를 선택할 수 있도록 하는 파일 그립핑 기능을 가지는 진동식 항타기에 관한 것이다.The present invention relates to a vibratory driving machine having a pile gripping function, and more particularly, it enables not only chucking of a pile by a pile chuck, but also gripping of a pile by a pile gripper, and thereby It relates to a vibratory driving machine having a pile gripping function that enables selection of direct driving and indirect driving using a separate driving machine.
일반적으로, 콘크리트 건축물이나 교량 또는 흙 물막이 및 각종 댐 등의 모든 구조물을 지반 위에 구축하기 위해서는 지반이 구조물의 중량을 견딜 수 있도록 콘크리트 파일이나 H 형강 파일 등을 매설하는 기초공사를 실시하고 있으며, 특히 연약지반의 경우는 지표면 아래의 지하층에 있는 암반에 파일을 박아 고정시키는 기초공사를 반드시 수행하고 있다.In general, in order to build all structures such as concrete structures, bridges, or earth clogs and various dams on the ground, the groundwork is carried out by burying concrete piles or H-beam piles so that the ground can withstand the weight of the structure. In the case of soft ground, the foundation work is always carried out by driving piles into the bedrock in the basement below the surface of the earth to fix it.
이와 같이 기초공사에 있어 파일을 지반에 박아주는 작업을 항타작업이라 하고 있으며, 오래전에 사용된 바 있는 항타작업은 지반에 매설하고자 하는 파일을 쇠뭉치로 된 중량체의 중량으로 타격하는 항타기와 유압이나 공압실린더를 이용하여 타격하는 항타기 및 디젤기름의 폭발력을 이용하여 타격하는 항타기 등을 이용하고 있었으나, 이러한 타격식 항타기 모두는 파일을 타격할 때 발생되는 타격소음이 크고, 타격시 충격 진동이 발생되어 공사현장의 주변에 환경공해를 유발시키는 문제점이 있었다. 따라서, 이러한 문제점을 해결하기 위하여 타격소음 및 충격진동이 적게 발생되는 진동식 항타기가 개발되어 사용되고 있다.In this way, the work of driving piles into the ground in the foundation work is called driving work, and the driving work that has been used for a long time is a driving machine that strikes a pile to be buried in the ground with the weight of a heavy metal ball, hydraulic or A driving machine that strikes using a pneumatic cylinder and a driving machine that strikes using the explosive power of diesel oil were used, but all of these striking types have a large hitting noise when hitting a pile, and shock vibration is generated when hitting. There was a problem that caused environmental pollution around the construction site. Therefore, in order to solve this problem, a vibration-type driving machine that generates less impact noise and impact vibration has been developed and used.
종래 기술에 따른 진동식 항타기로는 한국등록특허 제10-1675273호의 "진동식 항타기"가 제시된 바 있다. 이는 유압공급부를 지닌 건설기계의 붐에 결합되는 턴테이블을 지지하면서 좌측프레임 및 우측프레임을 구비한 메인프레임과, 상기 좌측프레임 및 우측프레임의 안쪽으로 끼워진 횡축에 의존되어 수평 및 수직 회동되는 서브프레임과, 상기 서브프레임 속에 방진수단으로 지지되면서 상기 유압공급부의 작동유에 따른 진동 유압모터에 의해 진동되는 진동뭉치와, 상기 진동뭉치의 하부에 고정되면서 상기 유압공급부의 작동유에 의해 파일을 탈착시키는 척과, 상기 유압공급부의 작동유에 따라 상기 횡축에 의존된 상기 서브프레임을 수평 및 수직 회동시키는 틸팅수단을 포함하는 진동식 항타기에 있어서, 상기 틸팅수단은 상기 메인프레임에 힌지 결합되어 상기 서브프레임의 틸팅시 상기 유압공급부의 작동유의 공급유무에 따라 로드를 수축 및 신장시키면서 상기 횡축에 결합된 링크를 역정회전시키는 실린더를 구비하고, 상기 좌측프레임 및 우측프레임은 상기 횡축을 끼움 받아들이면서 상기 로드의 수축 및 신장에 따라 상기 횡축의 역정 회전을 보장하는 원형구멍과, 상기 원형구멍의 상측으로 연장되어 상기 횡축의 역정 회전을 차단하는 각형구멍을 구비하고, 상기 횡축은 상기 서브프레임의 틸팅시 상기 로드의 수축 및 신장에 따라 상기 원형구멍 속에서 역정 회전되는 봉부와, 상기 파일을 항타하기 위하여 상기 붐을 누를 때 상대적으로 상기 원형구멍으로부터 상승되면서 상기 각형구멍 속으로 끼워져 역정 회전을 방지할 수 있도록 상기 봉부의 측단에 깎여진 단면부를 가진다.As a vibration-type driving machine according to the prior art, "vibration-type driving machine" of Korean Patent Registration No. 10-1675273 has been proposed. This includes a main frame having a left frame and a right frame while supporting a turntable coupled to the boom of a construction machine having a hydraulic supply unit, and a subframe that rotates horizontally and vertically depending on a transverse axis inserted into the left frame and the right frame; , a vibrating bundle supported by a vibration-proof means in the subframe and vibrated by a vibrating hydraulic motor according to the hydraulic oil of the hydraulic supply unit, and a chuck fixed to the lower part of the vibrating bundle and detaching the pile by the hydraulic oil of the hydraulic supply unit; In the vibratory driving machine comprising a tilting means for horizontally and vertically rotating the subframe depending on the transverse axis according to the hydraulic oil of the hydraulic supply part, the tilting means is hinged to the main frame and the hydraulic pressure supply part when the subframe is tilted a cylinder for reversely and forward rotating the link coupled to the transverse axis while contracting and extending the rod according to the supply or absence of the hydraulic oil of a circular hole for ensuring reverse rotation of the horizontal axis; and a rectangular hole extending above the circular hole to block the reverse rotation of the horizontal axis; The rod rotated backwards in the circular hole, and when the boom is pressed to drive the pile, it is inserted into the square hole while relatively rising from the circular hole to prevent reverse rotation. has a cross section.
그러나, 이와 같은 종래 기술은 척에 의해 파일의 단부를 잡게 됨으로써, 척과 파일의 접촉 면적이 충분하지 못하여 파일의 고정력이 부족할 수 밖에 없고, 별도의 항타기를 사용하여 파일을 항타하고자 하는 경우 파일의 단부에 위치하는 척과의 간섭으로 인해, 이를 어렵게 하는 문제점을 가지고 있었다.However, in this prior art, since the end of the pile is held by the chuck, the contact area between the chuck and the pile is not sufficient, so the fixing force of the pile is insufficient, and if you want to drive the pile using a separate driving machine, the end of the pile Due to the interference with the chuck located in the, there was a problem that made this difficult.
또한 종래의 다른 기술로서, 한국공개특허 제10-2014-0119778호의 "지반 내로 기둥을 해머링하는 해머링 장치"가 제시된 바 있다. 이는 기둥들(poles), 강철 프로필(steel profiles) 및 긴 물체들을 지상으로 해머링하는 해머링 장치로서, 상기 해머링 장치는, 파워 도구에 부착될 수 있는 몸체, 상기 몸체에 댐핑 쿠션(damping cushions)들에 의하여 부착되는 진동 장치, 및 상기 진동 장치에 적용되어서 유압 실린더와 같은 조절 유니트에 의하여 열거나 닫을 수 있는 그립 턱(gripping jaws)의 그립 요소의 측면 그립으로 해머링되는 물체를 잡기 위하여 이동할 수 있는 그립 턱들을 포함하며, 상기 그립 턱들이 이동하는 동안에 그립 턱들의 상호 대칭을 유지하기 위하여, 상기 그립 턱들의 회전 조인트들의 위치에서 견고하게 부착되는 아암들이 아암들의 단부들이 서로 간에 옆으로 위치되는 방향을 가지며, 상기 그립 턱이 회전 동작을 하는 동안에 서로 간에 옆에 위치하며, 상기 아암들의 단부들은 서로 피봇 장착되는 숏 아암에 의하여 서로 간에 연결된다.In addition, as another prior art, "a hammering device for hammering a column into the ground" of Korean Patent Application Laid-Open No. 10-2014-0119778 has been proposed. It is a hammering device for hammering poles, steel profiles and elongated objects into the ground, the hammering device comprising: a body attachable to a power tool, on damping cushions on the body a vibrating device attached to the vibrating device, and a gripping jaw adapted to the vibrating device to be moved for gripping an object being hammered with a side grip of a gripping element of gripping jaws that can be opened or closed by an adjustment unit such as a hydraulic cylinder. In order to maintain the mutual symmetry of the gripping jaws while the gripping jaws are moving, the arms being rigidly attached at the position of the rotational joints of the gripping jaws are oriented so that the ends of the arms are positioned laterally with respect to each other, The grip jaws are positioned next to each other during a rotational motion, the ends of the arms connected to each other by short arms pivotally mounted to each other.
그러나, 이와 같은 종래 기술은 유압 실린더가 어느 곳에도 고정되지 않은 상태에서 그립턱에 구동력을 전부 인가함으로써, 유압 실린더의 구동시 회전 조인트에 힘이 집중되어 회전 조인트의 파손을 유발하게 되는 문제점을 가지고 있었다.However, this prior art has a problem in that by applying all the driving force to the grip jaw in a state where the hydraulic cylinder is not fixed anywhere, the force is concentrated on the rotary joint when the hydraulic cylinder is driven, thereby causing damage to the rotary joint. there was.
