Abstract:
(EN) The present invention relates to a hydraulic striking device and construction equipment comprising the same. A hydraulic striking device according to an aspect of the present invention comprises: a cylinder; a piston; a forward/backward moving valve connecting a hydraulic source and a rear chamber of the cylinder, when in a forward movement position, such that a hydraulic pressure is applied to the rear chamber of the cylinder, thereby moving the piston forward, and the forward/backward moving valve connecting the rear chamber and a hydraulic tank, when in a backward movement position, such that the hydraulic pressure in the rear chamber of the cylinder is dropped, thereby moving the piston backward; and a first position valve and a second position valve for preventing a hydraulic pressure from being applied from a front chamber of the cylinder to the forward/backward moving valve, when in a first position, such that, in the process of arranging the forward/backward moving valve in the backward movement position and moving the piston backward, the piston does not move forward before the top dead point, and the first position valve and the second position valve applying the hydraulic pressure from the front chamber of the cylinder to the forward/backward moving valve, when in a second position, such that, in the process of arranging the forward/backward moving valve in the backward movement position and moving the piston backward, the forward/backward moving valve moves from the backward movement position to the forward movement position, thereby moving the piston forward before the top dead point.
(FR) La présente invention concerne un marteau à coup hydraulique et un équipement de construction le comprenant. Un marteau à coup hydraulique selon un aspect de la présente invention comprend : un cylindre ; un piston ; une soupape de déplacement vers l'avant/vers l'arrière reliant une source hydraulique et une chambre arrière du cylindre, lorsque dans une position de déplacement vers l'avant, de telle sorte qu'une pression hydraulique est appliquée à la chambre arrière du cylindre, déplaçant ainsi le piston vers l'avant, et la soupape de déplacement vers l'avant/vers l'arrière reliant la chambre arrière et un réservoir hydraulique, lorsque dans une position de déplacement vers l'arrière, de telle sorte que la pression hydraulique dans la chambre arrière du cylindre est diminuée, déplaçant ainsi le piston vers l'arrière ; et une première soupape de position et une seconde soupape de position pour empêcher une pression hydraulique d'être appliquée depuis une chambre avant du cylindre sur la soupape de déplacement vers l'avant/vers l'arrière, lorsque dans une première position, de telle sorte que, dans le processus d'agencement de la soupape de déplacement vers l'avant/vers l'arrière dans la position de déplacement vers l'arrière et de déplacement du piston vers l'arrière, le piston ne se déplace pas vers l'avant avant le point mort haut, et la première soupape de position et la seconde soupape de position appliquant la pression hydraulique depuis la chambre avant du cylindre sur la soupape de déplacement vers l'avant/vers l'arrière, lorsque dans une seconde position, de telle sorte que, dans le processus d'agencement de la soupape de déplacement vers l'avant/vers l'arrière dans la position de déplacement vers l'arrière et de déplacement du piston vers l'arrière, la soupape de déplacement vers l'avant/vers l'arrière se déplace de la position de déplacement vers l'arrière à la position de déplacement vers l'avant, déplaçant ainsi le piston vers l'avant avant le point mort haut.
(KO) 본 발명은 유압식 타격 기기 및 이를 포함하는 건설 장비에 관한 것으로, 본 발명의 일 양상에 따른 유압식 타격 기기는, 실린더; 피스톤; 전진 위치인 경우, 유압소스와 상기 실린더의 리어 챔버를 연결시켜, 상기 실린더의 리어 챔버에 유압을 인가하여 상기 피스톤이 전진 운동되도록 하고, 후진 위치인 경우, 상기 리어 챔버와 유압탱크를 연결시켜, 상기 실런더의 리어 챔버의 유압을 하강시켜 상기 피스톤이 후진 운동되도록 하는 전후진 밸브; 제1 위치인 경우, 상기 전후진 밸브가 후진 위치에 배치되어 상기 피스톤이 후진 운동되는 과정에서 상기 피스톤이 상사점 이전에 전진 운동되지 않도록 상기 실린더의 프론트 챔버에서 인가되는 유압이 상기 전후진 밸브로 인가되지 않도록 하고, 제2 위치인 경우, 상기 전후진 밸브가 후진 위치에 배치되어 상기 피스톤이 후진 운동되는 과정에서 상기 피스톤이 상사점 이전에 전진 운동되기 위하여, 상기 전후진 밸브가 후진 위치에서 전진 위치로 위치 이동되도록 상기 실린더의 프론트 챔버에서 인가되는 유압을 상기 전후진 밸브로 인가되도록 하는 제1 위치 밸브 및 제2 위치 밸브;를 포함한다.
