Pneumatic withdrawal type Pile driver
The present invention relates to a pneumatic withdrawable pile driver. At the time, the pneumatic withdrawable pile driver acts a combination of repulsive force and attractive force from the front and rear of a weight piston by compression and suction pneumatic pressure generated in mutually opposite directions in a plural volume chambers. Therefore, the pneumatic withdrawable pile driver generates high-load striking force in a small-sized lightweight structure having a short stroke and narrow eccentricity. In order to achieve the above, the present invention comprises: a pneumatic piston (10); the weight piston (20); a striking rod (30); a cylinder (100); first, second, and third volume chambers (110)(120)(130); and a variable cylinder (200).
본 발명은 공압 인출식 항타기에 관련되며, 이때 공압 인출식 항타기는 복수의 체적실에서 상호 역방향으로 발생되는 압축, 흡입 공압에 의해 중량피스톤 전, 후방에서 척력과 인력이 복합적으로 작용하여 짧은 스트로크와 협소한 편심량을 가진 소형 경량구조에서 고하중의 타격력이 발생되도록 하기 위해 공압피스톤(10), 중량피스톤(20), 타격로드(30), 실린더(100), 제1, 2, 3체적실(110)(120)(130), 가변실린더(200)를 포함하여 주요구성으로 이루어진다.
