Description

크레인용 고철절단기{THE SCRAP IRON CUTTING DEVICE USING THE CRANE}Scrap Metal Cutting Machine for Cranes {THE SCRAP IRON CUTTING DEVICE USING THE CRANE}

본 고안은 크레인의 암 끝단에 손쉽게 장착되어 유압으로 작동하여 고철을 절단하는 크레인용 고철절단기에 관한 것이다.The present invention relates to a scrap metal cutting machine for crane that is easily mounted on the arm end of the crane to operate hydraulically to cut scrap metal.

크레인용 고철절단기는 고가의 굴삭기의 선단에 연결하여 사용하는 고철절단기를 저가의 크레인의 선단에 연결하여 고철의 절단작업을 수행하도록 한것이다.The scrap scraper for crane is to cut scrap metal by connecting scrap scraper to the tip of low-cost crane.

따라서, 크레인의 선단에 보다 손쉽게 연결함과 동시에 굴삭기에 연결하여 사용하는 고철절단기보다 넓은 암 관절의 가동범위를 갖도록 많은 연구가 있어왔다.Therefore, much research has been conducted to have a wider range of motion of the arm joint than the scrap metal cutter used in connection with an excavator at the same time more easily connected to the tip of the crane.

예를 들면, 본 출원인이 선출원한 한국 특허출원번호 제20-2010-0000209호는 크레인의 암 끝단(1)에 고정 설치되며 내부에 유압라인을 배선할 수 있는 통로(13)를 마련하도록 한 관체(10); 상기 관체(10)에 회전되게 연결되는 제1커터(21)와, 관체(10)를 관통하는 유압라인과 연결된 채 제1커터(21)에 회전되게 연결되는 제2커터(26)로 이루어져, 유압에 의해 제2커터(26)가 제1커터(21)에 대해 벌어졌다 오므라지면서 고철을 절단하도록 한 커터수단(20); 상기 관체(10)의 일측에 설치되는 유압실린더(31)와, 일측은 유압실린더(31)의 로드(31a)와 회전되게 연결되고 타측은 관체(10)에 회전되게 연결되는 한 쌍의 제1링크(33)와, 일측은 유압실린더(31)의 로드(31a)가 회전되게 결합하는 제1링크(33)와 회전되게 연결되고 타측은 제1커터(21)에 회전되게 연결되는 한 쌍의 제2링크(35)로 이루어져, 상기 유압실린더(31)의 로드(31a)가 신축됨으로 인해 제1링크(33)와 제2링크(35)가 접철되어 커터수단(20)이 관체(10)에 대해 접철되도록 한 접철수단(30)을 포함하여 구성된 크레인용 고철절단기임을 알 수 있다.For example, Korean Patent Application No. 20-2010-0000209, filed by the present applicant, is fixed to the arm end 1 of a crane and has a passage 13 for providing a passage 13 through which a hydraulic line can be wired. 10; The first cutter 21 is rotatably connected to the tubular body 10, and the second cutter 26 is rotatably connected to the first cutter 21 while being connected to the hydraulic line passing through the tubular body 10, Cutter means (20) for cutting the scrap metal while the second cutter (26) is opened and closed with respect to the first cutter (21) by hydraulic pressure; The hydraulic cylinder 31 installed on one side of the tubular body 10, one side is connected to the rod 31a of the hydraulic cylinder 31 to be rotated and the other side is a pair of first rotatably connected to the tubular body 10 A link 33 and a pair of one side is rotatably connected to the first link 33 that the rod 31a of the hydraulic cylinder 31 is rotatably coupled, and the other side is rotatably connected to the first cutter 21. It consists of a second link 35, the first link 33 and the second link 35 is folded because the rod 31a of the hydraulic cylinder 31 is stretched, the cutter means 20 is the tubular body 10 It can be seen that the scrap metal cutting machine configured to include a folding means 30 to be folded about.

그러나, 상기와 같은 기술은 2개의 통공에 각각 고정핀을 끼워 결합되므로 각각의 통공에 고정핀들을 혼자서 정확히 끼우기가 곤란하여 두사람 이상이 항상 필요하여 개선점이 있어왔다.However, the above-described technology has been improved by inserting the fixing pins into the two holes, respectively, so that it is difficult to accurately fit the fixing pins alone in each of the two holes.

상기 해결수단에 의한 본 고안은 U자홈을 형성하는 지지체와 그 U홈에 끼워지는 몸체의 고정핀을 구비하여 크레인의 암 끝단에 손쉽게 탈부착하여 고철의 절단작업을 수행하고, 간편한 탈부착으로 유지 및 보수가 용이하며, 굴삭기용 고철절단기보다 넓은 암 관절의 가동범위를 갖는 크레인용 고철절단기를 제공하는데 있다.The present invention by the above solving means is provided with a support pin forming a U-shaped groove and a fixing pin of the body fitted into the U groove to easily detachable to the arm end of the crane to perform the cutting work of scrap metal, maintenance and repair by easy detachable It is easy to provide, and the scrap metal cutting machine for cranes having a movable range of the arm joint than the scrap metal cutting machine for excavators.
