Description

표면집진연마장치용 집진커버{cover for vacuum type surface grinding apparatus}Dust cover for surface dust polishing apparatus {cover for vacuum type surface grinding apparatus}

본발명은 표면집진연마장치용 집진커버에 관한것으로, 더욱상세하게는 별도의 흡입장치와 연결된 상태에서 연마면에 대한 연마날의 노출정도를 조정하는것에 의해 연마면에 대한 절삭깊이를 그때그때 미세조절되게하여 콘크리트 양생면의 거푸집 자국은 물론 기타 표면에 대한 각종 이물질 제거작업을 한결수월하게 수행함과 동시에 구성을 간단히하여 표면에 대한 연마작업효율을 높일수 있도록 한것이The present invention relates to a dust collecting cover for surface dust polishing apparatus, and more specifically, the depth of cut on the polishing surface is then finely adjusted by adjusting the degree of exposure of the polishing blade to the polishing surface in connection with a separate suction device. It is designed to improve the efficiency of polishing work on the surface by simplifying the construction and removing various foreign matters on the surface of the curing of the concrete and other surfaces.

다.All.

일반적으로 각종 콘크리트 공사현장에서 거푸집제거후 콘크리트 표면에는 거푸집경계부에 거푸집자국이 일정부분 돌출형성되게되어 콘크리트표면과 단차를 이루고 있는 것인바, 이경우 상기 양생된 거푸집자국을 없애기위해 그라인더등의 표면연마장치를 이용하여 작업자가 단차부를 연마하는것에 의해 양생완료된 콘크리트면을 균일한면으로 되도록 하고 있는것이었다.In general, after removing the formwork at various concrete construction sites, the form surface is projected to a certain part in the form boundary on the concrete surface to form a step with the concrete surface. By using the operator to polish the step, the cured concrete surface was made to be a uniform surface.

그러나 상기와 같이 양생완료된 콘크리트 표면에 형성되는 거푸집자국을 연마하여 표면을 매끄럽게 하기위한 연마장치는, 별도의 집진수단과 연결되는 별도의 덮개를 기존에 사용되고 있는 그라인더의 헤드부에 씌워 장착설치한 상태에서 그라인더에 장착된 연마날이 회전하면서 돌출된 거푸집자국을 갈아내게되고 이렇게 연마되는 과정에서 발생되는 콘크리트분진등의 찌꺼기는 덮개외측으로 호스에 의해 연결설치되는 흡입장치에 의해 흡입되어져 별도로 모아 처리되도록 하여 그라인더외부로 비산되는것을 방지하도록 하고 있는것이었다.However, the polishing apparatus for smoothing the surface by grinding the mold marks formed on the cured concrete surface as described above, the state is installed by mounting a separate cover connected to a separate dust collecting means to the head of the grinder used in the past The grinding blade mounted on the grinder rotates to grind out the protruding die marks, and the debris such as concrete dust generated during the polishing process is sucked by the suction device connected by the hose to the outside of the cover and collected and processed separately. To prevent them from flying out of the grinder.

그러나 상기와같이 거푸집자국을 연마하기 위해 사용되고있는 종래의 연마장치는 단순히 핸드그라인더 상면에 집진장치와 연결된 집진덮개를 불안정한 상태로씌운상태에서 사용되는것이므로, 거푸집자국에 대한 연마작업시 짚진덮개가 좌우로 요동되면서 소음을 발생시킬뿐만아니라, 연마과정에서 발생되는 콘크리트분진이나 찌꺼기등에 대한 흡입유도성능이 저하되어 연마된 콘크리트분진이나 찌꺼기들이 작업자측으로 비산되게 되는데 따른 작업자의 연마작업효율을 떨어뜨리게 되는 문제가 있는 것이었다.However, the conventional polishing apparatus used to grind the form marks as described above is simply used in a state where the dust cover is connected to the dust collector in the unstable state on the upper surface of the hand grinder, so that the straw cover is left and right when polishing the form marks. As a result of shaking, the noise is reduced, and the suction induction performance of the concrete dust or debris generated during the polishing process is reduced, thereby reducing the grinding work efficiency of the worker. There was.

또한 상기한 종래의 연마장치는 단순히 연마날이 회전되면서 표면으로 부터 돌출된 거푸집자국등의 돌출부를 연마하고 있는것이므로 작업자가 필요에따라 연마날의 돌출정도를 전혀 조절할 수 없는상태에서 연마면의 연마정도를 제대로 인지하지 못한채 연마작업이 이루어질수밖에 없으므로, 연마되는 표면이 전체적으로 고르게 연마되지않고 부분적으로 파형상으로 그 높낮이가 서로 다른 상태로 연마되게되어 보다 정밀한 연마면을 얻을수가 없게되는 문제가 있을뿐만아니라 그라인더 헤드부에 집진커버를 씌워서 되는 구조가 매우 복잡하고 분진흡입을 위한 연결관과 손잡이부가 별도로 형성되는데따라 연마면이 단순벽면이나 천정면을 불문하고 작업자가 연마장치를 잡고서 연마작업하는데 많은 어려움이 수반되어 콘크리트 표면에 대한 효율적인 연마가 이루어질수 없게되는 문제가 있는것이었다.In addition, the conventional polishing apparatus is simply polishing the projections such as die marks protruding from the surface while the grinding blade is rotated, so that the polishing of the polishing surface in a state where the operator can not adjust the degree of protrusion of the polishing blade as needed Since the grinding work can not be done without knowing the degree properly, the surface to be polished is not polished evenly as a whole, and the height of the surface is partially polished in different states so that a more accurate polishing surface cannot be obtained. However, the structure of the dust collector cover is very complicated, and the connection pipe and handle part for dust suction are formed separately. Therefore, it is difficult for the worker to hold and polish the grinding device regardless of the simple wall surface or the ceiling surface. Is accompanied by efficiency on the concrete surface There was a problem that can not be polished.

그리고 상기한 종래의 연마장치는 연마날의 노출정도를 조정할 수 없도록 그라인더 헤드부에 항상 일정부분 노출된상태이므로 그 적용범위에 있어서도 단순히 표면으로부터 돌출된 돌조들이나 연마가능할뿐 보다 정밀하고 미세한 표면연마, 예를들면 페인트도장면 제거나 미장면의 도배지 제거와 같은 정밀을 요하는 정교한 연마작업은 불가능하게되므로 그 사용범위에 있어서 어쩔수없이 제약을 받게되어연마장치의 사용성을 해치게 되는 문제가 있는 것이었다.In addition, since the conventional polishing apparatus is always partially exposed to the grinder head so that the exposure degree of the polishing blade cannot be adjusted, even in the scope of application, protrusions or polishing that are simply protruded from the surface are more precise and fine surface polishing, For example, it is impossible to elaborate the precise polishing work such as the removal of the paint surface or the removal of the unpainted surface, which is inevitably restricted in the range of use, which impairs the usability of the polishing device.

따라서 본 발명의 목적은, 상기와 같이 그라인더의 헤드부를 씌워 설치한상태에서 콘크리트표면에 돌출된 거푸집자국등의 돌출부를 연마처리하도록 한 종래의 표면집진연마장치용 집진커버가 지닌 제반문제점을 해결하기위하여, 기존에 사용되고 있는 핸드그라인더의 헤드부에 본체와, 이 본체외부에 커버링을 나사식으로 체결하여서 되는 집진커버를 견고하게 장착되도록하여, 연마되는 과정에서 발생되는 분진을 포함한 찌꺼기들이 본체에 의해 외부로 비산되지않고 흡입수단으로 흡입되도록함과 동시에 본체외주면에 나사결합된 커버링에 의해 연마날과 연마될 표면간의 거리를 미세조정토록함으로써 연마날에 의한 표면의 연마정도(깊이)조절이 가능하게되어 콘크리트표면의 거푸집자국제거작업등 일반적인 연마작업은 물론, 도장면이나 도배면등 표면에 대한 미세한 연마작업까지도 가능하게하여 그 사용성을 높일수 있도록한 표면집진연마장치용 집진커버를 제공함에 있다.Accordingly, an object of the present invention is to solve the problems of the dust collecting cover for the conventional surface dust collecting and polishing device to polish the protrusions such as formwork marks protruding from the concrete surface while covering the head of the grinder as described above. In order to securely mount the main body to the head portion of the hand grinder that is used and the dust cover which is screwed to the outside of the main body, the dust including the dust generated during the polishing process is externally provided by the main body. It is possible to adjust the degree of polishing (depth) of the surface by the polishing blade by allowing fine adjustment of the distance between the polishing blade and the surface to be polished by the cover screwed to the outer circumferential surface of the body without being scattered by the suction means. As well as general polishing work such as formwork international work on concrete surface, To enable even finer grinding of the surfaces described by arrays of dust-collecting surface of the cover for the dust collecting surface grinding device so that in turn, benefits that usability to provide.
