굴삭기의 아암(1)에 힌지 결합되는 링크결합몸체(12)의 일측에 집게(17)와 버켓(18)이 함께 설치되며, 상기 집게(17)와 버켓(18)은 링크(15,16)와 요크(14)에 의해 연결되고 상기 링크결합몸체(12)에 설치된 유압실린더(13)에 연결되어, 유압실린더(13)의 작동에 집게(17)와 버켓(18)이 함께 작동되는 구조로서, 보다 상세히 설명하면 다음과 같다.The tongs 17 and the bucket 18 are installed together on one side of the link coupling body 12 which is hinged to the arm 1 of the excavator, and the tongs 17 and the bucket 18 are links 15 and 16. And yoke 14 and connected to the hydraulic cylinder 13 installed in the link coupling body 12, the tongs 17 and the bucket 18 to operate in the operation of the hydraulic cylinder 13 as a structure In more detail, as follows.
굴삭기의 아암(1)과 실린더로드(3)에 일측부가 결합되는 링크결합몸체(12)와, 상기 링크결합몸체(12)의 타일측에 하나의 링크축(핀)(20)으로 결합되며 상부 일측에 연장부(17a,18a)가 형성된 집게(17)와 버켓(18)과, 상기 집게(17)와 버켓(18)이 결합된 상기 링크결합몸체(12)의 다른 일측에 결합되는 약간 유선형인 요크(14)와, 상기 요크(14)와 일측이 결합되고 타일측은 집게(17)와 버켓(18)의 연장부(17a,18a)에 결합되는 2개의 링크(15,16)와, 상기 링크결합몸체(12)에 설치되어 집게(17)의 연장부(17a)와 링크(15)의 결합부에 연결되는 유압실린더(13)로 구성되고,A link coupling body 12 having one side coupled to the arm 1 and the cylinder rod 3 of the excavator, and a link shaft (pin) 20 coupled to the tile side of the link coupling body 12 and having an upper portion. Slightly streamlined type coupled to the other side of the link coupling body 12 to which the forceps 17 and the bucket 18 and the forceps 17 and the bucket 18, on which one side is extended, 17a and 18a. In yoke 14, the yoke 14 and one side is coupled to the tile side is two links (15, 16) coupled to the tongs 17 and the extension (17a, 18a) of the bucket 18, and It is composed of a hydraulic cylinder 13 installed on the link coupling body 12 and connected to the extension portion 17a of the tongs 17 and the coupling portion of the link 15,
상기 집게(17)와 버켓(18)의 끝단부에는 끝단을 감싸도록 형성된 어댑터(23) 및 투스(24)가 형성되어 있으며,At the end of the forceps 17 and the bucket 18 is formed an adapter 23 and a tooth 24 formed to surround the end,
상기 링크결합몸체(12)에 결합되는 각 구성요소는 링크축(핀)(20)과 와셔(21)에 의해 결합되어 작동시 원활히 회전될 수 있도록 구성된 굴삭기용 작업집게인 것이다.Each component coupled to the link coupling body 12 is an excavator work clamp configured to be coupled by the link shaft (pin) 20 and the washer 21 to be smoothly rotated during operation.
본 발명의 동작과정을 살펴보면, 링크결합몸체(12)에 설치된 유압실린더(13)가 작동되면 도2와 같이 실린더로드(13a)가 이완되어 외부로 돌출되게 되어, 집게(17)의 연장부(17a)를 밀게 되어 집게(17)가 벌어지게 된다. 이에 따라 집게 연장부(17a)에 결합된 링크(15)가 벌어지게 되어 요크(14)와의 사이 각도가 커지게 되며, 집게 연장부(17a)와 요크(14) 사이에 위치하게 되는 버켓 결합용 링크(16)는 하강하게 되어 버켓(18)이 상승하게 된다.Looking at the operation of the present invention, when the hydraulic cylinder 13 installed on the link coupling body 12 is operated, as shown in Figure 2 the cylinder rod 13a is relaxed to protrude to the outside, the extension portion of the forceps 17 ( The tongs 17 are opened by pushing 17a). Accordingly, the link 15 coupled to the tong extension 17a is opened so that the angle between the yoke 14 is increased and the bucket is coupled between the tong extension 17a and the yoke 14. The link 16 is lowered and the bucket 18 is raised.
상기와 같이 본 발명은 유압실린더(13)가 작동되면, 링크결합몸체(12)의 링크축(핀)(20)을 중심으로 집게(17)와 버켓(18)이 벌어지게 된다.As described above, when the hydraulic cylinder 13 is operated, the tongs 17 and the bucket 18 are opened around the link shaft (pin) 20 of the link coupling body 12.
상기 유압실린더(13)를 역으로 작동시키면 도3과 같이 실린더로드(13a)가 수축되어, 상기 동작의 반대 과정에 의해 집게(17)와 버켓(18)이 닫히게 된다. When the hydraulic cylinder 13 is operated in reverse, the cylinder rod 13a is contracted as shown in FIG. 3, and the tongs 17 and the bucket 18 are closed by the opposite process.

이상에서와 같이 본 발명은 하나의 실린더로 구동력 제어작동에 따라 피지부 한 쌍에 버켓과 집게가 동시 똑같이 구동하여 물체를 파지하므로서, 종래의 버켓이나 집게 중 하나만 회동하여 작업반경이 긴데 반해 본 발명은 양쪽에서 회동하므로 잡업반경이 짧아 작업이 빠르고, 파지집게 연장부에 링크가 결합하고 요크에 작용으로 제어시 버켓과 집게로 물체를 잡을 경우, 물림 작용이 보다 부드럽고 확실하고 안전한 효과가 있는 것이다.As described above, according to the present invention, a bucket and tongs are simultaneously driven equally to a pair of sebum parts according to a driving force control operation by a single cylinder, so that only one of the conventional buckets or tongs is rotated, whereas the working radius is long. Is rotated on both sides, so the working radius is short, so the work is fast, and when the link is coupled to the gripper extension and the yoke acts on the object by the bucket and the tongs, the bite action is more smooth and secure.
