본 고안은 굴삭기의 붐 특히, 굴절식 붐의 각도조절장치에 관한 것으로서, 좀더 상세하게는 스플라인축과 실린더를 이용하여 간단하게 붐의 굴절각도를 조절하여 견고하게 굴절된 붐을 유지할 수 있도록 한 것에 관한 것이다.The present invention relates to an angle adjusting device of an excavator boom, in particular an articulated boom, and more specifically, by using a spline shaft and a cylinder by simply adjusting the angle of refraction of the boom to maintain a firmly refracted boom. It is about.
일반적으로, 굴삭기의 작업장치중에 하중이 많이 작용하는 부위중의 하나로서 보통의 붐은 작업하기에 알맞도록 일정각도로 구부러져 있다.In general, as one of the most heavily loaded parts of an excavator working device, an ordinary boom is bent at an angle to be suitable for work.
그러나, 최근 굴삭기의 붐은 작업요건에 따라 어느정도의 각도변환이 필요하게 되었다. 또한, 유럽등지에서는 도로교통법상 견인 또는 이동시에 차량의 외부로 돌출되는 부분에 대한 규제가 심하므로 굴절식 붐이 부착된 굴삭기가 필요하게 되었다.However, in recent years, the boom of an excavator requires some degree of angle change depending on the work requirements. In addition, in Europe, the road traffic law has severe restrictions on the parts protruding to the outside of the vehicle when towing or moving, so an excavator with an articulated boom is required.
그런데, 종래의 굴절식 붐을 가진 굴삭기의 경우는 상부붐과 하부붐을 핀으로 연결하고 상기 상부붐과 하부붐의 각도를 가변하거나 가변된 각도를 유지하기 위하여 실린더를 사용하였으나, 상기 상부붐과 하부붐에 집중되는 작업하중을 견디기 위하여는 실린더가 붐실린더 만큼이나 대용량이 되어야 하며 이에 따른 실린더 고정 구역시 커져 굴삭기 전체의 중량이 증가되었고, 실린더가 파손되는 등의 문제점이 발생하였다.By the way, in the case of a conventional excavator having an articulated boom, the cylinder is used to connect the upper boom and the lower boom with a pin and to change the angle of the upper boom and the lower boom or to maintain a variable angle. In order to withstand the work load concentrated on the lower boom, the cylinder should be as large as the boom cylinder, and accordingly, the weight of the excavator was increased due to the increase in the cylinder fixing area, and the cylinder was damaged.
본 고안은 상기와 같은 문제점을 제거하기 위하여 안출된 것으로서, 간단한 구조로 굴삭기 중량에 영향을 미치지 않으며 붐의 가변후에는 실린더에 전혀 하중이 걸리지 않도록 하며, 작은 용량의 실린더를 가변후에는 붐의 확실한 고정이 이루어지도록 하는데 목적이 있다.The present invention has been devised to eliminate the above problems, the simple structure does not affect the weight of the excavator, so that no load is applied to the cylinder at all after the boom variable, and after a small cylinder of the variable capacity of the boom The purpose is to make the fixation.
상기 목적을 달성하기 위한 본 고안의 특징은, 굴삭기의 붐이 상부붐과 하부붐으로 이루어진 통상의 굴삭기붐에 있어서, 상기 상부붐과 하부붐의 각도를 실린더로 조절을 하되, 상기 상, 하부붐 내측에는 양단에 스프라인축이 형성된 축 실린더를 장착하고, 상기 상, 하부붐의 내측에 스프라인을 형성시킨 구조로 된 것으로서, 첨부된 도면에 의하여 본 고안의 구성을 상세히 설명하면 다음과 같다.Features of the present invention for achieving the above object, in a conventional excavator boom consisting of an upper boom and a lower boom of the excavator, the angle of the upper boom and the lower boom with a cylinder, the upper, lower boom Mounted on the inside of the shaft cylinder is formed with a spline shaft on both ends, and the upper, lower boom as a structure that is formed in the structure, the configuration of the present invention in detail by the accompanying drawings as follows.
제1도에 도시한 바와 같이 굴삭기의 붐을 상부붐(1)과 하부붐(2)을 형성하여 상기 각붐의 일측에 실린더(3)를 장착한다. 그리고, 상기 상부붐(2)의 내측에는 제2도에 도시한 바와 같이 양측에 스프라인축(5)(5')이 설치된 축실린더(4)를 설치하고, 상기 스프라인축(5)(5')이 이동되는 상, 하부붐(1)(2)의 통로에는 스프라인을 형성하되 상기 스프라인축(5)(5')의 끝단에는 걸림부(6)(6')을 형성한 구조로 된 것이다.As shown in FIG. 1, the boom of the excavator forms an upper boom 1 and a lower boom 2 to mount the cylinder 3 on one side of each boom. And inside the upper boom 2, as shown in FIG. 2, shaft cylinders 4 provided with spline shafts 5 and 5 'are provided on both sides thereof, and the spline shafts 5 ( 5 ') is moved, the spline is formed in the passage of the lower boom (1) (2), but the engaging portion (6) (6') is formed at the end of the spline shaft (5) (5 ') It is a structure.
이와 같이 구성된 본 고안은 붐의 상, 하부붐(1)(2)의 각도를 변경하고자 할때는 축실린더(4)의 피스론로드를 내측으로 잡아당기게 되면 제2b도와 같이 스프라인축(5)(5')이 상부붐(1)의 내측으로 삽입되고, 그 끝단의 걸림부(6)(6')는 하부붐이 걸쳐 상부붐이 이탈되는 것을 방지한다.When the present invention configured as described above is to change the angle of the upper and lower booms (1) and (2) of the boom, and pulls the piston rod of the shaft cylinder (4) inward, as shown in the second spline shaft (5) ( 5 ') is inserted into the upper boom 1, and the locking portions 6 and 6' at the ends thereof prevent the upper boom from being detached over the lower boom.
상기와 같은 상태에서 붐의 외측에 설치된 실린더(3)를 작동시키게 되면 각도 변위가 이루어지게 되며, 상기 각도변화를 한후에는 다시 축실린더(4)가 제2b도와 같이 상기 동작과는 반대로 원위치되어 양붐을 견고히 고정시키게 되는 것이다.When operating the cylinder (3) installed on the outside of the boom in the state as described above, the angular displacement is made, and after changing the angle again the shaft cylinder (4) is in place as opposed to the operation as shown in Figure 2b and both booms It will be fixed firmly.
상기와 같은 본 고안은 적은 용량의 실린더를 이용하여 각도변위를 행한 후 완전히 고정을 하게되어 체결을 견고히 할 수 있고, 붐의 각도조절이 용이한 능의 효과가 있는 것이다.The present invention as described above is to perform a angular displacement by using a cylinder of a small capacity can be completely fixed to secure the fastening, there is an effect of the ability to easily adjust the angle of the boom.
