본 고안은 건설기계의 오퍼레이터의 운전실의 천정창유리 및 앞창유리를 보호하는 가이드에 관하며, 특히 운전실의 가아드부착장치에 관한다.The present invention relates to a guide for protecting a ceiling window glass and a front window glass of an operator's cab of an operator of a construction machine, and in particular, a guard attachment device of a cab.

종래로부터 유압셔블 등의 건설기계는 토사(土砂)의 굴착외에 여러가지 가혹한 작업에 사용되는데, 특히 쇄석작업이나 해체작업 등에 있어서, 굴착물의 비산정도가 많은 것에는 천정창이나 앞창이나 앞창의 유리를 보호하기 위해 네트가아드가 장착되어 있는 것이 있다.Conventionally, construction machines such as hydraulic excavators are used for various severe works besides excavation of earth and sand. Especially, in the case of crushing or dismantling work, the glass of the ceiling window, the front window, or the front window is protected against the scattering of the excavated material. Some are equipped with netguards.

즉, 예를 들면, 제2도에 표시하는 것은 운전실(21)의 천정창(22)과 앞창(23)부분에 별도로 네트(26),(27)를 각각의 프레임(28),(29)에 부착해서 네트가아드(24),(25)로서 볼트(30),(31)에 의해 고정한 것이 있다. 그밖에 구체적인 선행기술의 한가지예로서는 실개평 3-42848호 공보 등이 있지만 이것은 천정창은 없고 앞창에만 네트가아드를 설치한 것이다. 그러나, 제2도와 같이 구성된 네트가아드(24), (25)는 천정창용과 앞창용은 따로 따로 장착되어 있으므로, 특히 천정창용 네트가아드(24)는 운전실(21)에 대하여 천정판부의 웨이트부하가 되어서 제3도에 표시하듯이 운전실(21)의 옆요동을 증대시킨다.That is, for example, in FIG. 2, the nets 26 and 27 are separately provided in the ceiling windows 22 and the front windows 23 of the cab 21, respectively, in the frames 28 and 29, respectively. Some of the net guards 24 and 25 are fixed by bolts 30 and 31. Another specific example of the prior art is published in Unexamined-Japanese-Patent No. 3-42848, but this does not have a ceiling window and only a net guard is installed in the front window. However, since the net guards 24 and 25 configured as shown in FIG. 2 are mounted separately for the ceiling window and the front window, the net guard 24 for the ceiling window is particularly weighted against the cab 21. As a load, as shown in FIG. 3, the lateral fluctuation of the cab 21 is increased.

따라서 운전실(21)의 승차감의 악화나. 운전실(21)의 내구성에 영향이 미치게될 뿐 아니라 옆요동에 의한 변위에 의해 앞창용 네트가아드(25)의 균열(龜裂)에 이어지기도 하는 문제가 있었다.Therefore, the riding comfort of the cab 21 deteriorates. In addition to affecting the durability of the cab 21, there was a problem that the cracks of the front guard netguard 25 are caused by the displacement caused by the side swing.

본 고안은 이런 점에 조감하여 운전실의 천정부에 웨이트부하의 증대를 방지하고, 운전실의 내구성의 향상이나 승차감을 개선할 수 있는 운전실의 가아드부착장치를 제공하여 종래기술이 갖는 결점의 해소를 도모하는 것을 목적으로 하여 이루어진 것이다.In view of this, the present invention prevents an increase in weight load to the ceiling of the cab, and provides a cab guard attachment device that can improve the durability of the cab and improve the riding comfort, thereby solving the drawbacks of the prior art. It was made for the purpose of doing so.

상기한 목적을 달성하기 위하여 본 고안은, 건설기계의 운전실의 천정창유리부와 앞창유리부의 주위에 틀체 형상의 가아드부착용 서브프레임을 착탈가능하게 고정하고, 그위에 천전창 네트가아드와 앞창 네트가아드를 고정한 것을 특징으로 한다.In order to achieve the above object, the present invention is to detachably fix the frame-shaped guard attachment subframe around the ceiling window glass part and the windshield glass part of the cab of the construction machine, and the ceiling window net guard and the front net It is characterized by fixing the guard.

상기한 구성에 의하면 서브프레임에 의해 천정창부와 앞창부가 구속되고 따라서 운전실의 옆요동 변위가 억제된다. 제1도는 본 고안에 관계되는 운전실의 가아드부착장치의 일 실시예를 표시하는 분해한 사시도이다.According to the above configuration, the ceiling window portion and the front window portion are constrained by the subframe, thereby suppressing the lateral oscillation displacement of the cab. 1 is an exploded perspective view showing an embodiment of the guard attachment device of the cab according to the present invention.

이하 본 고안을 제1도에 표시하는 실시예를 참조하여 설명한다. 본 고안에 관계되는 운전실의 가아드부착장치는 건설기계의 운전실(1)의 천전창유리부(2) 및 앞창유리부(3)의 주위에 틀체형상의 가아드부착용 서브프레임(4)을 착탈가능하게 고정하고, 그위에 천정창 네트가아드(5) 및 앞창 네트가아드(6)를 부착한 것으로 구성되어 있다. 운전실(1)은 천정의 앞부분에 천전창유리부(2)가 설치되고, 앞부분에 위로부터 아래로 걸어서 전폭에 걸쳐서 앞창유리부(3)가 설치되어 있다. 그리고, 이들 유리부(2).(3)의 주위에는 서브프레임(4)을 부착하기 위한 복수개의 나사시이트(1a)가 고정되어 있다. 서브프레임(4)은, 천전창유리부(2) 및 앞창유리부(3)의 주의를 평판 또는 파이프 등에 의해 일체적으로 둘러쌓여서 틀체형상으로 하고, 또 운전실(1)의 형상을 따라서 굴곡으로 형성되어 있고, 그 하축 주위의 복수개소애는 운전실(1)꽈 결합하기 위한 볼트구멍(8)을 보유하는 시이트(7)가 용접 등에 의해 고정되어 있다. 그리고 그 상면에는 천정창 네트가아드(5) 및 앞창 네트가아드(6)를 부착하기 위한 복수개의 나사시이트(9)가 고정되어 있다.Hereinafter, the present invention will be described with reference to the embodiment shown in FIG. The guard attachment device of the cab according to the present invention can attach and detach the frame-shaped guard guard attachment subframe 4 around the skylight glass part 2 and the windshield glass part 3 of the cab 1 of the construction machine. And a ceiling window netguard 5 and a front window netguard 6 are attached thereto. The cab 1 is provided with a ceiling glass part 2 in the front part of the ceiling, and is provided with the windshield part 3 over the full width by walking from top to bottom in the front part. A plurality of screw sheets 1a for attaching the subframe 4 are fixed around the glass portions 2 and 3. The subframe 4 is integrally surrounded by a flat plate or a pipe with the attention of the windshield glass part 2 and the windshield glass part 3 to form a frame shape, and is curved along the shape of the cab 1. The sheet | seat 7 which has the bolt hole 8 for engaging with the cab 1 is fixed by welding etc. in the several places around the lower axis | shaft. On the upper surface, a plurality of screw sheets 9 for attaching the ceiling window net guard 5 and the front window net guard 6 are fixed.

천정창 네트가아드(5)는 틀체(10)와 네트(11)에 의해 구성되고 전면측은 상기한 서브프레임(4)의 형상에 맞추어서 굴곡된 형상으로 되어 있다. 앞창 네트가아드(6)는 천정창 네트가아드(5)와 마찬가지로 틀체(12)와 네트(13)에 의해 구성되며, 양 네트가아드(5), (6)가 모두 각자의 틀체(10), (12)에는 상기한 서브프레임(4)의 시이트(7)와 일치하는 표면 구석부 4개소에 볼트구멍(14)이 설치되어 있다.The ceiling window net guard 5 is comprised by the frame 10 and the net 11, and the front side becomes the shape bent according to the shape of the subframe 4 mentioned above. The front netgaard 6 is composed of a frame 12 and a net 13 similarly to the ceiling window netguard 5, and both netguards 5 and 6 have their own frame 10. ) And (12), bolt holes 14 are provided in four surface corner portions corresponding to the sheet 7 of the subframe 4 described above.

도면중, 부호(15), (16)은 각각 부착볼트이다.In the figure, reference numerals 15 and 16 denote attachment bolts, respectively.

그 다음에 작용에 대해 설명한다. 서브프레임(4)은, 상기한 바와 같이 앞창부로 부터 전정부까지 일체화되어 있어서, 이것을 운전실(1)에 볼트(16)에 의해 체결할때 운전실(1)의 네트가아드 부착부가 구속된다. 따라서 네트가아드(5), (6)의 부착에 의한 웨이트부하도, 이 서브프레임(4)으로 받게 되므로 운전실(1)의 옆요동부하는 경감된다. 네트가아드(5), (6)는 각각 서브프레임(4)이 나사시이트(9)의 위에 볼트구멍(14)을 중합하듯이 하여 볼트(15)에 의해 체걸하므로써, 장착이 완료되는데 네트가아드(5). (6) 자체도 변위하중의 경감에 의해 균열방지가 도모된다.Next, the operation will be described. As described above, the subframe 4 is integrated from the front window portion to the front government, and the net guard attachment portion of the cab 1 is restrained when the subframe 4 is fastened to the cab 1 by the bolt 16. Accordingly, the weight load due to the attachment of the net guards 5 and 6 is also received by the subframe 4, so that the side rocking load of the cab 1 is reduced. The netguards 5 and 6 are hung by the bolts 15 as if the subframe 4 polymerizes the bolt holes 14 on the threaded sheet 9, so that the netting is completed. Ad (5). (6) The cracks can be prevented by reducing the displacement load itself.

본 고안은 이상설명했듯이 건설기계의 운전실의 천정창 유리부 및 앞창유리부의 주위에 들체형상의 가아드부착용 서브프레임을 착탈가능하게 고정하고, 그위에 천정창 네트가아드 및 앞창 네트가아드를 고정했으므로 서브프레임식 네트가아드의 장착에 의해 종래에 발생한 운전실의 옆요동과 승차감의 악화. 운전실 내구성의 저하, 네트가아드의 균열 등이 방지되는 동시에, 또한 네트가아드의 경량화에 따라 네트의 착탈. 창유리 정소작업의부하저감 등의 효과를 기대할 수 있게 된다.The present invention, as described above, and detachably fix the field-shaped guard attachment subframe around the ceiling window glass part and the windshield glass part of the cab of the construction machine, and fixed the ceiling window net guard and the windshield net guard on it. As a result, deterioration of lateral fluctuations and ride comfort of the cab which have occurred conventionally by the installation of the subframe-type net guards. Deterioration of cab durability and cracks in the netguard are prevented, and the net can be removed from the netguard. It can be expected to reduce the load of window glass test work.
