Description

굴삭기의 운전사각 반사장치Driving angle reflector of excavator

제1도는 작업의 종류에 따른 운전자의 사각도.1 is a driver's blindness according to the type of work.

제2도는 본 고안의 실시예도.2 is an embodiment of the present invention.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 제1기어 2 : 제2기어1: first gear 2: 2nd gear

3 : 반사경 지지대 4 : 반사경3: reflector support 4: reflector

5 : 붐 6 : 아암5: boom 6: arm

본 고안은 붐, 아암, 버켓의 작동기를 갖춘 굴삭기에 있어서, 운전자의 시계성을 극대화 하기 위한 반사장치에 관한 것으로, 작업 조건에 따라서 운전자의 시각이 미칠수 없는 사각지대를 운전자가 볼 수 있도록 하기 위해 아암 또는 붐상에 반사경을 설치하고, 아암의 회전에 따라서 반사경의 반사각을 적절하게 변화시켜, 버켓 끝단의 입사각과 시각의 입사각이 같아지도록 하여, 운전자가 항상 버켓 끝단을 볼 수 있도록 만든 장치이다.The present invention relates to a reflector for maximizing the driver's visibility in an excavator equipped with an actuator of a boom, arm, and bucket, and to allow the driver to see a blind spot that the driver's vision cannot reach depending on working conditions. The reflector is installed on the arm or the boom, and the reflecting angle of the reflector is appropriately changed according to the rotation of the arm so that the angle of incidence of the bucket end and the angle of incidence of the visual angle are the same so that the driver can always see the end of the bucket.

종래의 굴삭기를 사용하여 제1도에 도시한 것과 같은 작업을 수행할 때에 운전자의 시각이 미칠수 없는 A의 사각지대에서는 운전자의 느낌에 의해서 운전할 수 밖에 없으므로, 정확한 작업을 수행할 수 없으며 안전사고의 위험도 뒤따르는 결점이 있었다.When performing a work like that shown in FIG. 1 using a conventional excavator, in the blind spot of A, which the driver's vision cannot reach, the driver can only drive by the driver's feeling. There was also a flaw that followed the danger.

본 고안은 이와같은 종래 기술의 문제점을 제거키 위해, 아암 또는 붐상에 반사경을 설치하여 어떤 작업 조건에서도 운전자의 시야를 확보할 수 있도록 한 것으로서 그 요지를 첨부도면 및 작용효과에 연계시켜 상세히 설명하면 다음과 같다.The present invention, in order to eliminate the problems of the prior art, by installing a reflector on the arm or the boom to ensure the driver's field of vision in any working conditions as described in detail in conjunction with the accompanying drawings and the effect effect As follows.

본 고안은 제2도에서 아암(6)의 회전에 따라 같이 회전하도록 기어축이 아암에 고정되고 기어는 붐(5)에 설치된 제1기어(1)와, 이와 맞물려 일정비율로 회전하도록 붐(5)상에 축설치된 제2기어(2)와, 이 기어축에 고정되어 같이 회전하는 반사경지지대(3)를 설치하며, 이 지지대에 고정된 곡면 또는 평면의 반사경(4)을 설치하는 구성인데 제1도에서와 같이 작업자의 시야가 닿지않는 A지역의 작업시에, 제2도의 버켓끝의 입사각 a1과 운전자의 시각의 입사각 a2가 같아지도록 반사경(4)을 설치되어 있어서, 아암(6)과 붐(5)의 위치가 변화해도 운전자가 버켓(7)끝단을 볼 수 있는 것이다.According to the present invention, the gear shaft is fixed to the arm so as to rotate together with the rotation of the arm 6 in FIG. 2, and the gear is engaged with the first gear 1 installed in the boom 5, and the boom is rotated at a fixed rate by engaging with the first gear 1. 5) the second gear (2) is installed on the shaft and the reflector support (3) is fixed to the gear shaft and rotates together, and the curved or flat reflector (4) fixed to this support As shown in FIG. 1, the reflector 4 is provided so that the angle of incidence a1 at the end of the bucket in FIG. 2 is equal to the angle of incidence a2 of the driver's time when the work is performed in the area A where the operator's view does not reach. Even if the position of the boom 5 and the driver can see the end of the bucket (7).

즉, 아암(6)이 회전하면 제1기어(1)가 회전하고, 제1기어(1)가 회전하면 일정한 비율로 제2기어가 회전하여 제2기어(2)상에 고정된 반사경지지대(3)와 반사경(4)가 같이 회전하여, a1, a2가 같아짐으로서 운전자가 항상 반사경(4)을 통하여 버켓(7) 끝단을 볼 수 있도록 구성된 장치이다.That is, when the arm 6 rotates, the first gear 1 rotates, and when the first gear 1 rotates, the second gear rotates at a constant rate to fix the reflector support fixed on the second gear 2 ( 3) and the reflector 4 are rotated together so that a1 and a2 become equal so that the driver can always see the end of the bucket 7 through the reflector 4.

이와같이 된 본 고안으로서 운전자는 어떤 작업조건에서도 버켓끝단을 보면서 작업할 수 있으므로, 보다 정밀한 작업을 할 수 있으며, 안전사고를 막을 수 있는 효과를 발생하여 본건 고품질의 굴삭기를 토목 건설 현장에 투입할 수 있는 것이다.With this design, the driver can work while looking at the end of the bucket under any working conditions, so that the operator can work more precisely, and the effect of preventing safety accidents can be put into the civil construction site. It is.

Claims (1)

운전자의 시야가 닿지 않는 곳을 운전자가 볼 수 있도록 버켓(7)끝의 입사각과 운전자의 시각의 입사각이 같아지도록 반사경(4)을 설치하되 그 각도를 제어하기 위해서, 아암(6)과 함께 회전하도록 붐(5)상에 설치된 제1기어(1)와, 제1기어(1)에 물려서 일정한 비율로 회전하는 붐(5)상에 설치된 제2기어(2)와, 제2기어(2)에 고정되어 반사경(4)을 지지하며 회전하는 반사경 지지대(3)를 결합한 것을 특징으로 하는 굴삭기의 운전사각 반사장치.Install the reflector 4 so that the angle of incidence at the end of the bucket 7 is equal to the angle of incidence of the driver's sight so that the driver can see where the driver's field of view is out of reach, but to control the angle, the rotation with the arm 6 A first gear 1 provided on the boom 5, a second gear 2 provided on the boom 5 which is bitten by the first gear 1 and rotates at a constant rate, and a second gear 2 Driving angle reflector of the excavator, characterized in that coupled to the rotating reflector support (3) is fixed to support the reflector (4).
