Description

굴삭기의 회전개폐식 언더커버Rotatable Undercover of Excavator

본 발명은 건설 중장비 중 굴삭기의 언더커버에 관한 것으로, 보수작업시 언더커버를 떼어내지 않고 1개의 볼트를 회전축으로 하여 언더커버를 회전시켜 엔진룸 내부가 개방된 상태로 만들어 보수작업이 용이하도록 하는 언더커버에 관한 것이다.The present invention relates to an undercover of an excavator among heavy construction equipment, and to maintain the inside of the engine room by opening the inside of the engine room by rotating the undercover with one bolt as a rotating shaft without removing the undercover during maintenance work, thereby making maintenance easy. It is about an undercover.

제1도는 종래기술에 따른 굴삭기의 언더커버의 분해상태를 도시한 상태설명도로서, 종래 굴삭기에서는 작업자가 보수작업을 하게 될 경우, 언더커버(1)의 각 모서리를 따라 다수개 결합된 볼트(5)를 모두 풀러서 상부 프레임(4)으로부터 언더커버(1)를 완전히 분리하고 나서 보수작업을 하여야 했다.1 is a state explanatory diagram showing an exploded state of the undercover of the excavator according to the prior art, in the conventional excavator when the operator is to repair, a plurality of bolts coupled along each corner of the undercover (1) ( After all 5) had been loosened, the undercover 1 was completely removed from the upper frame 4 and repaired.

따라서 작업자가 언더커버(1)의 마지막 볼트(5)를 풀 경우에는 한손으로 언더커버(1)를 떠받치면서 작업하여야 하며, 마지막 볼트(5)가 해체되면 언더커버(1)를 들어서 다른 장소로 옮긴 후 보수작업을 하여야 하므로 분해작업이 대단히 번거로울 뿐만 아니라, 언더커버(1)는 매우 무거우므로 작업자 1인이 옮기기 어렵고 허리부상의 위험성도 내재하는 것이다.Therefore, when the worker loosens the last bolt (5) of the undercover (1), it should work while holding the undercover (1) with one hand. When the last bolt (5) is disassembled, lift the undercover (1) to another place. Dismantling work is very cumbersome because it has to be repaired after moving, and undercover (1) is very heavy, so it is difficult for one worker to move and the risk of back injury is inherent.

본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 언더커버를 완전히 분리되는 구조로 하지 않고 한 개의 볼트를 회전축으로 하여 언더커버가 슬라이딩 되면서 열리는 구조로 구성하여, 보수작업을 작업자 1인이 용이하게 할 수 있도록 함에 목적이 있는 것이다.The present invention is to solve such a problem, and does not have a structure that is completely separated from the undercover, it consists of a structure that is opened while sliding the undercover by sliding one bolt as a rotating shaft, to facilitate the maintenance work by one worker The purpose is to make it possible.

이를 위한 해결방안으로서, 본 발명에서는 언더커버가 상부 프레임에 대해 볼트를 회전축으로 하여 슬라딩하면서 개폐되는 구조가 되도록 하고, 언더커버의 개폐동작이 원활이 이루어지도록 언더커버의 상부면에는 손잡이를 부착하고, 언더커버가 완전히 열리는 위치에서 언더커버가 개방된 상태를 유지할 수 있도록 언더커버 행거를 구성하고 있다.As a solution for this, in the present invention, the undercover is configured to be opened and closed by sliding the bolt with respect to the upper frame as the rotation axis, and the handle is attached to the upper surface of the undercover so that the opening and closing operation of the undercover is smoothly performed. The undercover hanger is configured to maintain the undercover in a fully open position.

첨부도면에 의해 본 발명을 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 발명에 따른 굴삭기의 언더커버를 도시한 상태설명도, 제3도는 제2도에서 A방향으로 관측한 본 발명의 측면도로서 언더커버가 개방된 상태를 설명한 측면도, 제4도는 제3도의 원형표시부만을 확대도시한 확대도시측면도, 제5도는 본 발명의 언더커버의 작동상태를 설명하는 작동설명도로서, 상기 도면에서 보면, 굴삭기의 상부 프레임(4)의 하부에 위치하여 각 모서리부를 따라 나합되는 볼트(5)들에 의해서 결합되어지는 굴삭기의 언더커버에 있어서, 상기 언더커버(1)의 일측 모서리부에 나합되는 볼트(5')를 회전축으로 슬라이딩 개폐가 용이한 구조로 이루어지고 그 상부에는 손잡이(2)가 부착되어 있으며, 언더커버(1)가 완전히 열려진 상태에서는 언더커버(1)의 개방상태가 유지될 수 있도록 언더커버(1)의 단부가 내측에 걸려지면서 수용되는 꺾임부가 형성된 언더커버 행거(3)가 상부 프레임(4)에 결합되어져 있다.FIG. 2 is an explanatory view showing an undercover of an excavator according to the present invention. FIG. 3 is a side view of the present invention as viewed in the direction A in FIG. 2 and a side view illustrating an open state of the undercover. 5 is an explanatory view illustrating an operating state of the undercover of the present invention. As shown in the above drawings, each corner portion is located below the upper frame 4 of the excavator. In the undercover of the excavator coupled by the bolts (5) to be screwed together, it is made of a structure that is easy to open and close the sliding bolt (5 ') to be joined to the corner portion of the undercover (1) with a rotating shaft A handle (2) is attached to the upper portion, and the end of the undercover (1) is accommodated while being held inward so that the open state of the undercover (1) can be kept in a state where the undercover (1) is fully open. The under cover hanger (3) has been formed in the fold back portion coupled to the upper frame (4).

본 발명에 따른 언더커버(1)에는 손잡이(2)가 부탁되어 있고 상부프레임(4)에는 언더커버 행거(3)가 부착되어 있으므로 작업자는 언더커버(1)의 6개 볼트(5)(5')중 5개의 볼트(5)를 떼어내고 회전중심이 되는 볼트(5')를 반쯤 풀은 후, 손잡이(2)를 잡고 언더커버(1)를 회전시켜 언더커버 행거(3)에 끼워넣고 고정시킨 후 개방된 상부 프레임 내부의 보수작업을 수행할 수 있게 된다.The handle 2 is attached to the undercover 1 according to the present invention, and the undercover hanger 3 is attached to the upper frame 4, so that the operator has six bolts 5 and 5 of the undercover 1. Take off the five bolts (5) of '), loosen the bolt (5') which is the center of rotation, hold the handle (2) and rotate the undercover (1) and insert it into the undercover hanger (3). After fixing, it is possible to perform maintenance work inside the opened upper frame.

이때 언더커버(1)의 단부는 언더커버 행거(3)의 꺾임부 내에 걸려 고정되는 상태가 되어, 상부 프레임 내부의 보수작업 중 언더커버(1)는 움직이지 않는 상태가 되므로 작업자는 안전하게 보수작업을 할 수 있게 되는 것이다.At this time, the end portion of the undercover 1 is caught and fixed in the bent portion of the undercover hanger 3, and the undercover 1 is not moved during the maintenance work inside the upper frame, so the worker is safely repaired. You will be able to.

이와 같이 본발명 장치는 언더커버를 완전히 분리되는 구조로 하지 않고 한 개의 볼트를 회전축으로 하여 언더커버가 슬라이딩 되면서 열리는 구조로 구성하여, 보수작업을 작업자 1인이 용이하게 할 수 있도록 하고, 작업자가 보수작업을 위해 언더커버를 다른 장소로 분리하여 옮길 필요가 없으므로 신속하고도 안전한 작업이 가능토록하는 우수한 발명이다.As such, the present invention does not have a structure in which the undercover is completely separated, but has a structure in which one bolt is used as a rotating shaft to open the slide while the undercover slides, so that one worker can easily perform maintenance work. It is an excellent invention to enable fast and safe operation because there is no need to separate and move the undercover to another place for maintenance work.
