본 고안은 굴삭기에 장착되어 각종 고철을 절단할 수 있도록 하는 굴착기용 고철 유압절단기의 고철절단능력을 보유하는 유압장치의 기본절단능력을 보다 월등한 파워의 절단능력(소형이면서도 중급이상의 작업능력 발휘)을 발휘하여 고철작업의 능률향상은 물론 장비구입에 따른 경제적 부담을 최소화시키고, 나아가 절단기의 바람직한 설치구조를 제공하는 파워 고철절단기에 관한 것이다.The present invention is equipped with an excavator that can cut various scraps. The cutting capacity of the hydraulic system that has the scrap cutting ability of the scrap metal hydraulic cutting machine for excavators is superior to the cutting capacity of the power. The present invention relates to a power scrap metal cutting machine which improves the efficiency of scrap metal work as well as minimizes the economic burden of equipment purchase and further provides a desirable installation structure of the cutting machine.

통상의 굴삭기용 고철절단기는 본래 흙을 파내는 건설장비의 일종인 굴삭기의 아암의 끝단에 장착된 버켓을 탈락시킨 후 그 자리에 가위형상의 유압고철절단기를 설치하여 고철작업의 용도로 사용할 수 있도록 변형한 고철작업기로서, 고철을 대량으로 취급하는 고철수거 및 판매상 등에는 필수적으로 갖추어야 할 장비 중 하나이다.Ordinary scrap metal cutting machine is a type of construction equipment to excavate the soil, dropping the bucket mounted on the end of the arm of the excavator, and then the scissors-shaped hydraulic scrap cutting machine installed in place to transform it for use in scrap work As a scrap metal working machine, it is one of the essential equipment for scrap scrapers and sellers who handle scrap metal in large quantities.

그런데 종래의 굴삭기용 고철절단기는 그 장비에서 갖추고 있는 기본적인 유압시스템 사양의 유압능력에 따른 고철절단능력밖에 발휘하지 못함에 따라, 고철취급장에서는 원만한 작업을 하기위해 필요한 절단능력을 가진 장비구입시 협소한 작업장에서 조작 및 취급이 상당히 불편한 중형/대형장비를 필요이상의 고가비용으로 구입해야하는 문제점이 있었다. 이러한 문제점은 고철 취급장의 어려운 경제적 부담을 더욱 가중시킬 뿐 아니라 특히 소규모의 고철사업장의 경우는 작업공간의 부재로 인해 그 고철절단장비 구입 자체를 포기해야 하는등 시급한 해결이 요구된다.However, the conventional scrap scraper for excavators exhibits only scrap cutting ability according to the hydraulic capacity of the basic hydraulic system specification provided by the equipment, so that the scrapyard has a narrow supply when cutting equipment having the necessary cutting capacity for smooth operation. There was a problem that a medium / large equipment that is quite inconvenient to operate and handle in one workplace has to be purchased at a higher cost than necessary. This problem not only adds to the difficult economic burden of the scrap metal handling station, but also needs to be urgently solved, especially in the case of small scrap workplaces, due to the absence of a work space, the purchase of the scrap cutting equipment itself has to be abandoned.

한편, 통상의 굴삭기용 절단장치는 굴삭기 아암 끝단의 고정핀을 중심으로 가위형태의 고정날과 작동날이 각각 대각으로 교차 구성시킨 상태에서 그 고정핀 부근의 아래측 작동날 부분과 굴착기의 아암 일측부 사이에 구동용 유압실린더가 구성되는 불합리한 설치구조를 취하고 있기 때문에 절단작업시 동일유압조건하에서 보다 큰 절단능력을 발휘하지 못할 뿐만 아니라 고철 취급시 그 실린더의 외부 노출에 따른 고장율이 커 잦은 교체 및 수리작업을 해야하는 불편함과 경제적 손실등의 불가피한 문제점이 있었다.On the other hand, the conventional cutting device for excavators is the lower working blade portion near the fixing pin and the working arm of the excavator in the state where the fixed blades and the working blades of the scissors type are formed diagonally around the fixing pins at the end of the excavator arm. Since it has an unreasonable installation structure in which the hydraulic cylinder for driving is formed between the side parts, it is not able to exhibit greater cutting capacity under the same hydraulic condition during cutting work, and the failure rate is increased due to the external exposure of the cylinder when handling scrap metal. There was an unavoidable problem such as inconvenience and economic loss to repair.

즉, 상기한 실린더는 작동날의 중심축에 근접된 위치의 부분에 실린더의 로드가 연결되어 있어서 가압력 증대에 필수적 요건인 지렛대 원리의 이용효율성이 낮아 동일유압조건에서 발휘되는 절단파워가 떨어지는 문제점이 있었고, 또한 상기한 유압 실린더가 외부로 노출된 상태라 열악한 고철작업중 날카로운 고철과의 접촉 등으로 쉽게 훼손되거나 파손될 우려가 커 잦은 수리 및 교체에 따른 기타 손실이 불가피한 문제점이 있었다.That is, the cylinder has a problem that the cutting power exhibited under the same hydraulic conditions is low because the utilization of the lever principle, which is an essential requirement for increasing the pressing force, is lowered because the rod of the cylinder is connected to the position near the central axis of the working blade. In addition, since the hydraulic cylinder is exposed to the outside, there is a problem that other losses due to frequent repairs and replacements are inevitably damaged due to contact with sharp scrap metal during poor scrap work.

이에 본원에서는 상기한 문제점을 일소하기 위해 안출한 것으로서, 고철절단기의 기본 유압장치의 사양에 비해 절단날 동작 실체인 절단실린더의 출력압을 증압하여 보다 높은 절단능력을 발휘할 수 있도록 한 것과; 절단기의 고정절단날과 대응하는 구동절단날의 구동시 동일 유압조건에도 보다 높은 절단파워를 발휘하고, 외부노출에 따른 고장 등의 원인도 방지되는 절단날 구동용 실린더의 바람직한 설치구조를 제공하는 것에 주안점을 두고 그 기술적 과제로서 완성한 것이다.Therefore, in the present application to solve the above problems, and to increase the output pressure of the cutting cylinder which is the cutting blade operating entity compared to the specifications of the basic hydraulic device of the scrap metal cutter to exhibit a higher cutting capacity; To provide a desirable installation structure of the cylinder for driving the cutting blade that exhibits higher cutting power even under the same hydraulic condition when driving the fixed cutting blade of the cutter and the corresponding driving cutting blade, and also prevents the cause of failure due to external exposure. The main focus is on the technical task.

위 기술적 과제를 달성하기 위해 본원에서는 첨부된 도면에 의거 보다 상세히 설명하면 하기와 같다.In order to achieve the above technical problem, the present invention will be described in detail with reference to the accompanying drawings.

즉, 도 1에서 도시된 바와 같이 굴착기 아암(미도시)의 끝단에 고정날(111)이 장착된 고정날 지지프레임(110)이 고정되고, 상기 고정날 지지프레임(110)과 축(130)이 연결된 상태에서 유압실린더 푸시로드(100)의 작동에 따라 절단작동되는 작동절단날(121)을 가진 작동날 지지프레임(120)이 설치된 굴착기 장착용 고철절단기(A)를 구성함에 있어서,That is, as shown in FIG. 1, the fixed blade support frame 110 is fixed to the end of the excavator arm (not shown) is mounted with a fixed blade 111, the fixed blade support frame 110 and the shaft 130 In constructing the excavator mounting scrap cutter (A) for mounting the operating frame support frame 120 having the operating cutting blade 121 is cut in accordance with the operation of the hydraulic cylinder push rod 100 in this connected state,

상기 고정날 지지프레임(110)을 일측과 타측간 "ㄷ"자 형으로 형성한 후 그 사이 내측에 절단작동용 유압실린더(100)를 설치하되, 그 유압실린더(100)는 "ㄷ"자 형 고정날 지지프레임(110)의 일측과 타측간 회전핀(101)으로 고정되는 한편, 그 실린더(100)의 푸시로드(102) 끝단은 구동날 지지프레임(120)의 상단에 결합한 것과;After forming the fixed blade support frame 110 in a "c" shape between one side and the other side, the hydraulic cylinder 100 for cutting operation is installed therebetween, but the hydraulic cylinder 100 is a "c" shape One end and the other side of the fixed blade support frame 110 is fixed to the rotation pin 101, the end of the push rod 102 of the cylinder 100 is coupled to the upper end of the drive blade support frame 120;

상기 고정날 지지프레임(110)에 엄폐된 상태의 실린더(100) 상단에 그 실린더(100)에 인가되는 기본 유압호스(미도시)의 경로에 유압실린더(100)가 가지는 기본 파워를 보다 크게 확대작용할 수 있도록 증압시키는 별도의 증압기(10)를 추가 설치하여서 된 것이다.The basic power of the hydraulic cylinder 100 in the path of the basic hydraulic hose (not shown) applied to the cylinder 100 on the top of the cylinder 100 in the state of being covered by the fixed blade support frame 110 is greatly enlarged. It is to install a separate pressure intensifier 10 to increase the pressure to act.

이와 같이 구성되는 본 고안의 굴삭기 장착용 파워 고철절단기는 상술된 바와 같이 절단기의 구동날을 작동시키는 유압 실린더가 고정날 지지플레임의 양지지체 사이에서 외부로 노출되지 않은 엄폐상태로 구성함에 따라 작업 중 고철 등과의 접으로 인한 고장이나 파손의 우려가 대폭 해소될 수 있을 뿐 아니라 ,Excavator mounting power scrap cutting machine of the present invention configured as described above is in operation as the hydraulic cylinder for operating the drive blade of the cutter as described above is configured in a closed state that is not exposed to the outside between both supports of the fixed blade support frame. The risk of breakdown or damage due to contact with scrap metal can be greatly resolved.

상기한 실린더는 양날의 중심축의 상단부에서 구동날 지지프레임의 상단 끝단부를 푸시로드로 작동하기 때문에 보다 효율적 지렛대원리 응용으로 인한 고효율 절단능력 발휘에 일조할 수 있다.Since the cylinder operates as a push rod at the upper end of the drive blade support frame at the upper end of the central axis of the two blades can contribute to high efficiency cutting ability due to more efficient lever principle application.

그리고 특히 굴삭기에 설치된 유압모터에서 인가된 유압이 실린더측으로 인가되는 유압순환호스의 일단에 그 유압을 상당한 압력까지 증강하는 증압기가 설치됨에 따라 굴삭기에 설치된 유압모터의 기준 사양 이상의 절단능력을 발휘할 수 있어서, In particular, since an intensifier is installed at one end of the hydraulic circulation hose in which the hydraulic pressure applied from the hydraulic motor installed in the excavator is applied to the cylinder side, the cutting force can exhibit cutting capability beyond the standard specification of the hydraulic motor installed in the excavator. In

소형의 굴삭기로 중,대형의 굴삭기와 이상의 작업능률(절단능력)을 얻을 수 있는 결과가 될 수 있는바, 경제적이나 작업장의 공간면에서 열악한 소규모 영세업체의 경우 상당한 도움이 될 수 있다.Small excavators can result in greater efficiency than the medium and large excavators, which can be of great help to small and small businesses that are economically poor in terms of workplace space.

한편, 상기한 증압기(10)는 산업체의 각종 공작기계 중 유압을 이용한 절곡기 등에서 일부적용된 사례를 있으나 본원과 같은 굴삭기 장작용 고철절단기에 적용된 사례는 현재까지 보고된 바가 없다.On the other hand, the pressure intensifier 10 has been applied in some cases, such as a bending machine using hydraulic pressure among various machine tools of the industry, but the case applied to the excavator long-acting scrap metal cutter as described herein has not been reported to date.

이에 본 고안의 굴삭기 장착용 파워 고철절단기는 고철작업시 요구되는 상당두께의 고철을 아주 효율적일 뿐 아니라 특히 굴삭기가 가진 기본 유압력의 최대 가압력 보다 월등한 절단 파워를 발휘할 수 있는 등 아주 유용한 고안이다.Therefore, the power scrap cutting machine for excavator mounting of the present invention is a very useful design such that the scrap metal having a considerable thickness required for scrap work is very efficient, and in particular, it can exert cutting power superior to the maximum pressing force of the basic hydraulic power of the excavator.
