상기 도면에 도시된 바와 같이 굴착기 메인 붐의 암 선단과 작동링크의 선단에 형성된 핀홀에 버켓, 브래커, 착암기 등 굴착장비의 양측 브라켓에 삽입결합되 어 체결시키는 체결핀에 있어서 중심부에는 통공(12)이 형성된 중공축으로 일측끝단부에는 단턱부(14)가 형성된 핀부싱(10)이 체결용 핀(20)의 양끝단에 형성되어 암 선단과 작동링크의 선단에 형성된 핀홀(52)과 굴착장치의 브라켓통공(62)에 연결결합되어 이루어진 굴착기의 굴착장비 착탈용 체결핀(1)이다.As shown in the drawing, a pin hole formed at the tip of the arm of the excavator main boom and the tip of the operation link is inserted into and coupled to both brackets of the excavating equipment such as a bucket, a breaker, a rock drill, and a hole in the center thereof. A pin bushing 10 having a stepped portion 14 formed at one end of the hollow shaft having a hollow shaft) is formed at both ends of the fastening pin 20 to excavate with the pinhole 52 formed at the tip of the arm and the operation link. The fastening device detachable fastening pin 1 of the excavator, which is connected to the bracket through-hole 62 of the device.

상기 핀부싱(10)은 핀(20)과 결합할 있도록 중심부에는 통공(12)이 형성된 중공축으로 일측끝단부에는 단턱부(14)가 형성된 핀부싱(10)은 충격음이 굴착기의 메인붐 및 핀(20)으로 이동하는 것을 방지한다. The pin bushing 10 is a hollow shaft formed with a through-hole 12 in the center so as to be coupled to the pin 20, the pin bushing 10 formed with a stepped portion 14 at one end thereof is the impact boom main boom and To prevent movement to the pin 20.

상기 단턱부(14)의 폭은 크기는 굴착장비(50)와 굴착기(60)가 연결결합되는 공간에 따라 달라질 수 있다.The width of the step portion 14 may vary in size depending on the space in which the drilling rig 50 and the excavator 60 are coupled.

상기 핀부싱(10)의 재질은 충격을 방지하는 충격흡수재로 형성될 수 있으며 더욱더 충격 및 소음을 방지하기 위해 충격완화용 비철(40)이 핀부싱의 외주면에 형성될 수 있다. The material of the pin bushing 10 may be formed of a shock absorbing material to prevent the impact, and shock-absorbing nonferrous 40 may be formed on the outer circumferential surface of the pin bushing to further prevent shock and noise.

이와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다. Referring to the operation of the present invention configured as described above are as follows.

도 5에 도시한 바와 같이 굴착장비가 분리된 상에서 굴착기(60) 메인 붐의 암선단 및 작동링크를 분리된 굴착장비(50)에 연결시키고자 할 경우에는 먼저 굴착장비(50)의 통공(52)에 핀부싱(10)을 삽입 후 굴착기(60)의 암선단과 작동링크의 통공(62)이 핀부싱(10)이 삽입된 통공(12)과 일치하도록 굴착장비(50)에 삽입 후 통공으로 체결용 핀이 삽입된 후 일측끝단에는 체결용 핀이 이탈되지 않도록 조임볼트를 마무리해 준다. As shown in FIG. 5, in order to connect the female tip of the excavator 60 main boom and the operation link to the separated drilling rig 50 on the separated drilling rig, the through hole 52 of the drilling rig 50 first. After inserting the pin bushing (10) into the hole of the excavator 60 and the through-hole 62 of the operation link is inserted into the drilling equipment (50) to match the through-hole 12 in which the pin bushing 10 is inserted through the through-hole After the fastening pin is inserted, one end of the fastening bolt is finished so that the fastening pin is not separated.

이와 같이 연결된 굴착기는 작업시 굴착장비의 충격이 핀부싱으로 충격흡수 되어 굴착기의 암선단과 작동링크를 보호 및 굴착장비와 굴착기의 연결되는 체결핀을 충격으로부터 보호되어 체결핀의 수명을 연장되며 또한 작업으로 인한 충격이 핀부싱으로 흡수되어 충격소음이 격감되는 효과가 있다.In this connection, the excavator is shock-absorbed by the pin bushing during operation, thereby protecting the female tip and the operating link of the excavator and protecting the fastening pin connected between the excavator and the excavator from shock, thus extending the life of the fastening pin. The shock caused by the work is absorbed by the pin bushing, thereby reducing the impact noise.
