In addition to improving work efficiency and enabling use for various purposes, it provides excellent utilization due to the wide range of strength of the work object, and provides a prefabricated assembly structure that is easy to replace the hydraulic motor, which requires maintenance and repair. It relates to a twin-head drum cutter capable of reducing time and cost, and an excavator having the same.
일반적으로, 굴삭기는 건축 및 토목 공사시, 땅을 파거나 메우는 굴삭작업, 경토ㆍ암반 파쇄 등의 브레이커 작업, 흙다짐과 같은 컴팩터 작업, 절단 등의 크라샤 작업을 수행하도록 하는 건설기계를 말한다.In general, an excavator refers to a construction machine that performs crushing work such as excavation work to dig or fill the ground, breaker work such as light soil and rock crushing, compactor work such as soil compaction, and cutting during construction and civil engineering works. .
이러한 굴삭기는 보통 주행 동력을 얻기 위해 디젤 엔진 등의 엔진을 탑재하고 있고, 이 엔진의 힘을 이용하여 유압 펌프를 구동하며, 유압 펌프에서 토출되는 작동유를 유압 모터나 유압 실린더 등의 유압 액추에이터로 공급함으로써 주행용 크롤러 또는 타이어의 회전이나, 붐, 아암, 버켓 등의 각 작업 부위를 동작시키고 있다.These excavators are usually equipped with an engine such as a diesel engine to obtain driving power, drive a hydraulic pump using the power of this engine, and supply hydraulic oil discharged from the hydraulic pump to a hydraulic actuator such as a hydraulic motor or a hydraulic cylinder. By doing so, rotation of the crawler or tire for traveling, and each working part such as a boom, an arm, and a bucket are operated.
이러한 굴삭기는 굴삭작업을 위하여, 아암의 단부에 커터가 마련되는데, 종래 굴삭기의 커터와 관련되는 기술로는, 한국등록실용신안 제20-0288999호의 "터널공사용 굴진장치"가 개시된 바 있다. 이는 굴삭기 등의 아암 선단에 선택적으로 장착될 수 있도록 아암 결합부를 가지는 베이스부; 상기 베이스부에 고정 설치되는 모터; 상기 모터에 의해 회전 가능하도록 베어링을 매개로 상기 베이스부에 설치되는 것으로서, 외면 전체에 걸쳐 다수의 파쇄용 비트가 밤송이처럼 돌출 형성되며, 선단이 불룩한 유선 형태로 폐쇄되어 있는 원통형 용기 형상의 드럼을 포함한다.Such an excavator is provided with a cutter at the end of the arm for excavation work. As a technique related to the cutter of the conventional excavator, the "excavator for tunnel construction" of Korean Utility Model No. 20-0288999 has been disclosed. It includes: a base portion having an arm engaging portion so as to be selectively mounted to an arm tip of an excavator or the like; a motor fixedly installed on the base part; A drum in the shape of a cylindrical container that is installed on the base part through a bearing so as to be rotatable by the motor, a plurality of crushing bits protrude like chestnuts over the entire outer surface, and the tip is closed in a bulging streamline shape. include
그러나, 이와 같은 종래 기술은 굴삭과 관련되는 다양한 작업에 확대 적용하는데 한계를 가짐으로써, 활용도를 높이기 어렵고, 굴삭 효율 면에서 유리한 구조를 제공하지 못함으로써, 이에 대한 개선이 필요하게 되었다.However, since the prior art has a limitation in being expanded and applied to various operations related to excavation, it is difficult to increase the utilization and does not provide a structure advantageous in terms of excavation efficiency, so improvement is required.
또한, 종래의 굴삭기에는 아치형 드럼 커터를 구비하는 경우가 있는데, 이는 커터가 아치형으로 이루어짐으로써, 역시 효율이 저하되고, 유압모터가 프레임에 용접되어 있기 때문에, 유압모터의 수리 또는 교체를 위한 분리가 불가능하여, 유압모터에 연결된 유압베이스에 문제가 있으면, 굴삭기 전체를 사용하지 못하게 되는 문제점을 가지고 있었다.In addition, there is a case in which the conventional excavator is provided with an arcuate drum cutter, which is made in an arcuate shape, so that efficiency is also reduced, and since the hydraulic motor is welded to the frame, separation for repair or replacement of the hydraulic motor is difficult. Impossible, if there is a problem in the hydraulic base connected to the hydraulic motor, there was a problem that the entire excavator could not be used.
상기한 종래 기술에 대한 문제점을 해결하기 위하여, 본 발명은 굴삭기의 드럼 커터를 트윈으로 구성할 뿐만 아니라, 커터의 효율적인 배치 구조와 유압모터의 효율적인 동력 사용을 가능하게 함으로써, 강력한 파쇄력을 발생하도록 하여 작업 효율을 향상시키고, 프로파일링, 트렌칭, 연암파쇄, 석산작업, 철거 등과 같은 다양한 용도로의 사용이 가능하도록 할 뿐만 아니라, 버켓이나 유압브레이커 등에 비하여, 작업 대상의 강도 범위가 넓어 활용도가 뛰어나며, 유압모터의 교체가 용이한 조립식 어셈블리 구조를 제공함으로써, 유지 및 보수에 소요되는 시간과 비용을 줄이는데 목적이 있다.In order to solve the problems of the prior art, the present invention not only configures the drum cutter of the excavator in twins, but also enables an efficient arrangement structure of the cutter and efficient use of power of the hydraulic motor to generate a strong crushing force. This improves work efficiency and makes it possible to use it for various purposes such as profiling, trenching, soft rock crushing, quarry work, and demolition. It is excellent and aims to reduce the time and cost required for maintenance and repair by providing a prefabricated assembly structure that is easy to replace the hydraulic motor.
