Description

굴삭기 장착용 집게 받침대Clamp pedestal for excavator mounting
본 발명은 굴삭기에 장착함으로써 상기 굴삭기의 버켓과 짝을 이루어 집게로 사용할 수 있게 해주는 굴삭기 장착용 집게 받침대에 관한 것이다.The present invention relates to a clamp support for mounting an excavator, which can be used as a clamp by pairing with a bucket of the excavator by mounting on an excavator.
일반적으로 굴삭기는 암(arm)의 끝단에 달린 버켓(bucket)으로 흙이나 자갈 등을 퍼올리는데 사용되며, 상기 버켓은 집게와 같은 다른 장착물로 교체 설치가 가능하도록 마련된다.In general, an excavator is used to scoop up soil or gravel with a bucket attached to the end of an arm, and the bucket is provided to enable replacement with other attachments such as tongs.
따라서, 굴삭기를 이용하여 통나무, 파이프, 바위 등을 집어올리기 위해서는 버켓을 집게로 교체한 다음 작업에 임할 수 있으므로 교체작업이 번거롭다는 문제와 함께 별도의 유압식 집게를 장만하여 두어야 한다는 문제가 있으며, 특히 미니굴삭기의 경우에는 굴삭작업 중에도 수시로 현장 작업자를 도와 물건을 들어올리거나 나르는 작업을 병행해주어야 할 필요가 있는데 그때마다 버켓을 집게로 교체한다는 것은 여러모로 불편하다는 문제가 제기되었다.Therefore, in order to use an excavator to pick up logs, pipes, rocks, etc., since the bucket can be replaced with tongs and then the work can be started, there is a problem that replacement work is cumbersome and a separate hydraulic tongs must be provided. In particular, in the case of a mini excavator, it is necessary to frequently help field workers during excavation work to lift or carry items, but the problem of replacing the bucket with tongs each time is inconvenient in many ways has been raised.
이러한 문제를 해결하기 위해 출원인은 한국실용신안등록출원 제20-2018-0004676호, 한국실용신안등록출원 제20-2018-0006133호 및 한국실용신안등록출원 제20-2019-0003057호의 발명들을 제안한 바 있다.To solve this problem, the applicant has proposed the inventions of Korea Utility Model Registration Application No. 20-2018-0004676, Korean Utility Model Registration Application No. 20-2018-0006133, and Korean Utility Model Registration Application No. 20-2019-0003057 have.
