본 발명은 미장기계의 회전방지를 위한 안전장치에 관한 것으로서 보다 상세하게는 미장작업시 작업자가 핸들을 놓쳤을 때 핸들이 회전하면서 안전사고를 일으키게 되는 것을 방지하도록 한 미장기계의 회전방지를 위한 안전장치에 관한 것이다.
The present invention relates to a safety device for preventing the rotation of the plastering machine, and more particularly, the safety device for preventing the rotation of the plastering machine to prevent the handle is rotated when the operator misses the handle during the plastering operation to cause a safety accident It is about.

일반적으로 건물 또는 주택등을 건설할 경우 타설된 콘크리트 벽체나 바닥 또는 조적벽체 등에는 마감 모르타르를 시공한 후 그 표면에 도색을 하거나 벽지등을 바르는 등의 후공정을 거쳐 시공을 완료하게 됨은 주지와 같다. In general, when building a building or a house, the finished concrete mortar, floor or masonry wall is finished with a finishing process such as painting the wall or painting the surface after finishing the mortar. same.

이때 마감 모르타르의 표면은 평탄한 수평 또는 수직을 유지해야 하는데, 종래에는 마감 모르타르의 평탄한 시공을 위해 실 등을 필요두께에 맞추어 종횡으로 설치하여 이를 기준으로 작업을 진행하고 있다.At this time, the surface of the finishing mortar should maintain a flat horizontal or vertical, conventionally, for the flat construction of the finishing mortar is installed in the longitudinal and horizontal direction according to the required thickness, and work is performed based on this.

그러나, 이러한 모르타르 시공방법은 많은 실을 종횡으로 설치하여야 하므로 작업준비에 많은 시간이 소요되고, 작업진행중 기준실의 유동이 발생되므로 작업면의 평탄상태를 유지하기 힘들다는 문제점들이 지적되고 있으며, 따라서 고도의 숙련자가 많은 시간 동안 작업을 진행해야 하므로 시공비가 과대히 상승하게 되는 주요인을 제공하게 된다.However, these mortar construction methods require a lot of yarn to be installed vertically and horizontally, so it takes a lot of time to prepare for the work, and it is difficult to maintain the flatness of the working surface because the flow of the reference chamber occurs during the operation. Highly skilled workers have to work for many hours, thus providing the main driver of excessively high construction costs.

또한, 상기한 문제점들에도 불구하고 시공된 마감 모르타르의 표면은 수평 또는 수직을 유지하기 어려우므로, 도색을 하거나 벽지를 바르고 난후에는 그 표면의 평탄상태가 불량하여 마감 모르타르의 시공목적을 상실하게 되고, 이에 따라 전체적인 건설품질이 저하된다는 점도 문제점으로 지적된다.In addition, despite the above problems, the surface of the finished mortar is difficult to maintain the horizontal or vertical, so after painting or wallpapering the surface of the finished mortar loses the purpose of construction of the finished mortar Therefore, it is pointed out that the overall construction quality is deteriorated accordingly.

상기와 같은 문제점을 감안하여 마감 모르타르의 시공을 기계적으로 수행하여 작업소요시간과 인력의 최소화에 의한 원가절감과 생산성 향상을 적극적으로 구현하고, 시공된 마감 모르타르의 표면을 평탄상태로 유지시킴으로써 건설품질의 대폭향상을 도모할 수 있게 된 자동 미장장치가 제안된바 있다.In consideration of the above problems, the construction of the finishing mortar is performed mechanically to realize cost reduction and productivity improvement by minimizing the work time and manpower, and the construction quality of the finished mortar is kept flat. Automatic plastering apparatus has been proposed that can greatly improve the

이하 본 발명의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도 2a는 본 발명의 구조를 보여주는 정면사시도이고 도 2b는 본 발명의 구조를 보여주는 배면사시도로서 이에 따르면 본 발명의 안전장치(100)는 미장기계의 일정부위에 고정하는 고정공(210)이 형성되고 내측에 공간부(220)를 구비한 하우징(200)의 외측에 회전축에 의해 회전 가능하게 설치된 스위치수단(300)이 설치되며, 상기 측면으로는 금속재로 이루어진 하우징(200)에 -전원을 연결할 수 있도록 리벳이 설치되는 통공(230)을 형성이 형성되어 있다.Figure 2a is a front perspective view showing the structure of the present invention and Figure 2b is a rear perspective view showing the structure of the present invention according to the safety device 100 of the present invention, the fixing hole 210 for fixing to a certain portion of the plastering machine Is formed and the switch means 300 is rotatably installed on the outer side of the housing 200 having a space portion 220 therein, the rotation means being installed by a rotating shaft, the side of the power supply to the housing 200 made of metal It is formed to form a through-hole 230 is installed rivet so that it can be connected.

한편 상기 스위치수단(300)의 회전축에 고정 설치되어 스위치수단(300)의 회전방향에 따라 회동하며 통공(230)의 리벳에 일측이 연결되어 -전원이 흐르는 하우징(200)과 연결하는 전선의 타측이 전원연결공(410)에 삽입되면 전선을 고정하는 고정부재(500)가 설치되어 이루어진 회동전원연결레버(400)가 회전되게 설치되며, 상기 전원선이 회동전원연결레버(400)가 접지되어 전원을 연결하는 접지판부재(600)가 설치된다.Meanwhile, it is fixedly installed on the rotating shaft of the switch means 300, and rotates according to the rotation direction of the switch means 300, and one side is connected to the rivet of the through hole 230, and the other side of the wire connecting the housing 200 through which the power flows. When inserted into the power connection hole 410, the rotational power connection lever 400 is installed to rotate the fixing member 500 is fixed to the wire is installed, the power supply line is connected to the rotational power connection lever 400 is grounded Ground plate member 600 for connecting the power is installed.

한편 상기 하우징(200)과 접지판부재(600) 사이에는 절연수단(700)을 설치하는 것이 바람직하다. 그 이유는 전원공급시 누전이 일어나는 것을 방지하기 위함이며, 상기 접지판부재(600)에는 엔진에 전원을 공급하는 전원선이 설치되는 단자(800)를 포함하여 이루어진 구조이다.On the other hand, it is preferable to install the insulating means 700 between the housing 200 and the ground plate member 600. The reason for this is to prevent a short circuit occurs during power supply, and the ground plate member 600 includes a structure including a terminal 800 on which a power line for supplying power to the engine is installed.

상기와 같은 구조로 이루어진 본 발명의 작동을 살펴보면 엔진(1)에 전원을 공급하여 미장판(16)을 회전시켜 미장작업을 실시할 때 첨부도면 도 3에 도시된 바와 같이 전원을 공급하여 미장기계를 사용할 때 회동전원연결레버(400)가 접지판부재(600)의 반대 방향쪽으로 회동되어 있어 상기한 회동전원연결레버(400)와 접지판부재(600)가 전기적으로 단락되어 있는 상태이다.Looking at the operation of the present invention made of a structure as described above when supplying power to the engine (1) by rotating the plastering plate 16 to perform the plastering work as shown in Figure 3 attached to the plastering machine When using the rotary power connecting lever 400 is rotated in the opposite direction of the ground plate member 600, the rotary power connecting lever 400 and the ground plate member 600 is in a state of being electrically shorted.

이때 상기 전원공급은 미장기계에 고정공(210)을 이용하여 고정 설치된 하우징(200)의 통공(230)에 고정 설치되는 리벳에 의하여 -전원이 흐르는 하우징(200)에 전선의 일측이 연결되고 상기 하우징과 연결된 -전기가 흐르는 전선의 타측은 전원연결공(410)에 삽입되면 전선이 고정부재(500)에 의해 고정되면서 전기적으로 연결되어 있어 회동전원연결레버(400)가 -전원을 통전하게 된다.At this time, the power supply is a rivet that is fixedly installed in the through-hole 230 of the housing 200 is fixed to the plastering machine using a fixing hole 210-One side of the wire is connected to the housing 200 through which the power flows and the When the other side of the wire connected to the housing-flowing electricity is inserted into the power connection hole 410 and the wire is fixed by the fixing member 500 and electrically connected, the rotational power connecting lever 400 is energized. .

한편 상기한 회동전원연결레버(400)에는 -전기가 흐르게 되고, 상기 회동전원연결레버(400)는 접지판부재(600)과 접지되어 않은 상태이다. 따라서 전원이 공급된 상태에서 작업자는 핸들을 잡고 있기 때문에 안전하게 미장작업을 기계적으로 수행하여 작업소요시간과 인력의 최소화에 의한 원가절감과 생산성 향상을 적극적으로 구현하고, 시공된 마감 모르타르의 표면을 평탄상태로 유지시킴으로써 건설품질의 대폭향상을 도모할 수 있다.Meanwhile, -electricity flows through the rotational power connection lever 400, and the rotational power connection lever 400 is not grounded with the ground plate member 600. Therefore, since the worker is holding the handle while the power is supplied, the plasterer can safely perform the mechanical work to realize cost reduction and productivity improvement by minimizing the work time and manpower, and smooth the surface of the finished mortar. By maintaining it in a state, the construction quality can be greatly improved.

그러나 상기한 미장기계를 이용한 미장작업 중 작업자가 부주위에 의하여 핸들을 놓치게 되면 기계의 구심점이 핸들부분에서 미장판 쪽으로 이동되어 작업자가 잡고 있던 핸들이 회전하게 된다. However, if the operator misses the handle by the circumference during the plastering operation using the plastering machine, the centripetal point of the machine is moved toward the plasterboard from the handle portion to rotate the handle held by the operator.

이때 첨부도면 도 4에 도시된 바와 같이 원심력에 의해 전기가 흐르는 회동전원연결레버가 회전됨으로 회동전원연결레버(400)와 접지판부재(600)의 연결상태가 전기적으로 연결됨으로 전원공급이 차단되어 엔진(1)구동을 정지시키게 되는 것이다.In this case, as shown in FIG. 4, as the rotary power connecting lever is rotated by centrifugal force, the power supply is cut off as the connection state of the rotary power connecting lever 400 and the ground plate member 600 is electrically connected. The engine 1 stops driving.

상기 회동전원연결레버(400)가 원심력에 의해 회전되면 회전축에 고정 설치된 스위치수단(300)도 회동전원연결레버(400)의 회전방향과 동일한 방향으로 회동하게 됨으로 전원의 연결상태를 외부에서 용이하게 확인할 수 있는 것이다. When the rotational power connection lever 400 is rotated by the centrifugal force, the switch means 300 fixedly installed on the rotating shaft also rotates in the same direction as the rotational direction of the rotational power connection lever 400, thereby easily connecting the power source from the outside. You can check.

따라서 작업도 중 핸들을 작업자가 놓치었을 때 핸들이 회전하게 되는데 이때 상기한 핸들이 일정각도로 회전되면 원심력에 의해 안전장치가 작동하여 미장기계로 공급되던 전원을 차단시켜 정지시킴으로 안전사고를 미연에 방지할 수 있는 효과가 있는 것이다.Therefore, when the worker misses the handle during the operation, the handle is rotated. At this time, when the handle is rotated by a certain angle, the safety device is operated by centrifugal force to cut off the power supplied to the plastering machine and stop the safety accident. There is an effect that can be prevented.

상기 본 발명에서는 회동전원연결레버(400)가 회동전원연결레버(400)와 전기적으로 연결되어 있다가 원심력에 의해 단락됨으로 엔진구동이 정지되는 것으로 설명하고 있으나 반대로 도면에는 미도시 되어 있으나 회동전원연결레버(400)가 회동전원연결레버(400)와 전기적으로 단락되어 있다가 원심력에 의해 연결되게 구조를 변경하여 사용할 수도 있다.
In the present invention, the rotational power connection lever 400 is electrically connected to the rotational power connection lever 400, but the engine driving is stopped by being shorted by centrifugal force. The lever 400 may be electrically shorted with the rotational power connecting lever 400 and then used by changing the structure to be connected by centrifugal force.
