Description

브이벨트용 안전분리공구{safety separation tool for v-belt}Safety separation tool for v-belt

본 발명은 브이벨트용 안전분리공구에 관한 것으로, 상세하게는 전동기 등에 연결하여 동력을 전달하는 브이벨트를 안전하고 편리하며 간편하게 분리할 수 있도록 하는 브이벨트 분리용 공구에 관한 것이다.The present invention relates to a safety separation tool for a V-belt, and more particularly, to a V-belt separation tool that enables a safe, convenient and simple separation of a V-belt that transmits power by connecting to an electric motor.

브이벨트는 천과 고무로 만든 단면이 V자형의 벨트이고, 전동기나 송풍기 또는 팬류 등의 V자형 풀리에 걸어서 사용하는 것으로, 고속이며 미끄럼이 적은데다 동력전달력과 전동능력이 좋으며 소음이 적어 다양한 산업현장에 설치되어 사용되고 있다.V-belt is a V-shaped belt made of cloth and rubber, and is used by hanging it on a V-shaped pulley such as an electric motor, blower, or fan. It is high-speed, low-slip, good power transmission and low noise. It is installed and used in industrial sites.

이러한 브이벨트는 이음이 없는 폐곡선의 둥근 모양 벨트로 회전력을 전달하는 가요성의 단면을 V형으로 만든 것이며, 포를 넣은 합성고무를 가압하여 만들고, 운전이 안정적이므로 동력 전달효율이 크고, 동력의 크기에 따라 필요한 개수대로 평행하게 사용하는 것으로, 사용 중, 길이가 신장되거나 과다하게 마모되어 기능저하가 발생하고 심한 경우 정확한 동력전달이 불가능하기 때문에 일정기간 사용 후 마모상태 등에 따라 새로운 브이벨트로 교체해주어야 한다.This V-belt is a closed-curved, seamless belt that has a flexible cross section that transmits rotational force in a V-shape, and it is made by pressing synthetic rubber containing fabric, and because the operation is stable, the power transmission efficiency is large and the size of the power. It is used in parallel as many times as necessary. During use, the length is elongated or worn excessively, resulting in deterioration of function. In severe cases, accurate power transmission is impossible. do.

이러한 이유로 브이벨트를 교체할 경우, 마땅한 교체장비가 없어 드라이버 혹은 그와 유사한 도구를 사용하여 풀리와 브이벨트 사이에 대각선상으로 끼우고 풀리를 회전시켜면서 브이벨트를 풀리로부터 벗겨 분리하였다. For this reason, when replacing the V-belt, there is no suitable replacement equipment, so a screwdriver or similar tool was used to insert the V-belt diagonally between the pulley and the V-belt, rotate the pulley, and remove the V-belt from the pulley.

그러나 이러한 브이벨트 분리작업은 브이벨트를 교체할 때마다 드라이버 등의 도구를 경사지게 끼우고 풀리를 회전시킴으로써, 이를 각각 수행할 수 있는 2명 이상의 인원이 필요로 할 뿐만 아니라 작업 시간이 많이 소요되어 효율이 저하됨과 동시에 작업자의 손이 풀리와 벨트 사이에 끼여 손가락 협착사고 등 산업재해가 종종 발생하는 문제점이 있었다.However, this V-belt separation operation requires two or more people to perform each operation by inserting a screwdriver or the like inclinedly and rotating the pulley whenever the V-belt is replaced. At the same time as this deterioration, there was a problem that the worker's hand was caught between the pulley and the belt, causing industrial accidents such as finger pinch accidents.

이러한 문제점을 해결하기 위하여 종래의 기술로는 등록실용신안 제20-0309047호의 '브이벨트 교체용 공구'도 있으나 단순히 공구를 원거리에서 브이벨트 와 풀리 사이에 위치시켜 90도 측방으로 공구를 젖혀 브이벨트를 분리하도록 하고 있으나 실질적으로 브이벨트의 장력이 강해 풀리로부터 브이벨트를 거의 분리하기 불가능한 문제점이 발생하므로 이를 원활하게 하기 위해 풀리를 별도로 무리하게 회전시키거나 공구를 강하게 두들겨 충분한 지지점을 확보할 수 있는 위치로 이동시켜 브이벨트를 분리하여야 번거로움으로 작업성이 크게 저하되었다.In order to solve this problem, there is also a'V-belt replacement tool' of Registration Utility Model No. 20-0309047 as a conventional technique, but simply place the tool between the V-belt and the pulley at a distance and tilt the tool to the side of the V-belt at 90 degrees. However, since the tension of the V-belt is substantially strong, it is impossible to separate the V-belt from the pulley. To facilitate this, the pulley is rotated separately or the tool is strongly beaten to secure a sufficient support point. The workability was greatly degraded due to the hassle when the V belt was removed by moving it to the position.

더욱이, 종래의 기술은 상기와 같은 과정에서 손으로 풀리를 회전시키거나 타격공구를 사용하므로 안전사고 발생 및 기기의 훼손 우려가 높은 문제점이 발생하였다.Moreover, in the prior art, since the pulley is rotated by hand or a hitting tool is used in the process as described above, there is a high concern about occurrence of a safety accident and damage to the device.

따라서 본 발명의 주목적은 안전하고 편리하며 안정적으로 브이벨트를 분리할 수 있도록 하여 안전사고로 발생을 방지할 수 있도록 하는 브이벨트용 안전분리공구를 제공하는 데 있다.Therefore, the main object of the present invention is to provide a safety separation tool for a V-belt that enables the V-belt to be safely, conveniently and stably separated, thereby preventing the occurrence of a safety accident.
