본 고안은 스키드 스티어 로다를 정비시 상승시킨 붐을 안전하게 지지시키도록한 스키드 스티어 로다 붐 하강방지장치에 관한 것이다.The present invention relates to a skid steer rod boom lowering prevention device to securely support a raised boom during maintenance of the skid steer rod.
종래에는 스키드 스티어 로다를 정비할 경우에는 장비에 보다 가깝게 접근하기 위하여 붐을 상승시키는 경우가 있게 되는데 운전자의 부주의 또는 타인의 부주의로 붐 작동페달이 작동되거나 유압라인의 손상으로 상승되어 있는 붐이 하강하는 경우가 있어 안전사고가 발생되는 문제점이 있었다.Conventionally, when a skid steer loader is maintained, the boom may be raised to get closer to the equipment, but the boom operation pedal is activated due to the carelessness of another driver or another person, or the boom raised due to damage to the hydraulic line is lowered. There was a problem that a safety accident occurs.
본 고안은 상기에서와 같은 종래의 문제점을 해결하고, 붐을 최대로 상승시킨 상태에서 운전자가 레스트랜트바를 들어 올리면 레스트렌트바에 연결된 링크장치가 작동하여 붐 고정핀이 상승된 붐을 잡아주어 붐의 하강을 방지하도록한 스키드 스티어 로다 붐 하강방지장치를 제공함에 있다.The present invention solves the conventional problems as described above, and when the driver lifts the rest land bar in the state in which the boom is raised to the maximum, the link device connected to the rest land bar operates to hold the boom with the boom fixing pin raised. It is to provide a skid steer rod boom lowering prevention device to prevent the lowering.
이하 첨부된 도면에 의하여 본 고안을 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 레스트렌트바의 구조를 보인 사시도로서, 절곡된 다수의 연결간(11)을 연설한 레스트렌트바(1)의 끝단에 케이블(2)이 연결되어 레스트렌트바(1) 승하강작동에 따라 푸쉬케이블(2)이 전후진 되도록 한 것이다.1 is a perspective view showing the structure of the rest rent bar, the cable (2) is connected to the end of the rest rent bar (1), which is a plurality of bent connection between the connection 11, the rest of the rest rent bar (1) According to the push cable (2) is to be moved forward and backward.
제2도는 본 고안의 구성을 보인 것으로서, 양측에 위치한 붐(7)의 하방에 각각 설치한 가이드관(6)에 전후진 되는 작동핀(5)을 결합하고, 이 작동핀(5)은 작동핀(5)의 중앙부에는 축설한 아암(3)의 양측에 각각 링크(4)로 연결하며, 아암(3)의 한측에 레스트렌트바(1)와 연결된 푸쉬케이블(2)을 연결하여 레스트렌트바(1)의 작동에 따라 작동핀(5)이 입출되도록 한 것이다.2 is a view showing the configuration of the present invention, coupled to the operation pins 5 which are advanced back and forth to the guide pipes 6 respectively installed below the booms 7 located on both sides, and the operation pins 5 are operated. The center portion of the pin (5) is connected to both sides of the arm (3) arranged in the link (4), respectively, one side of the arm (3) by connecting the push cable (2) connected with the rest rent bar (1) In accordance with the operation of the bar (1) is to enable the operation pin (5) to be entered.
이와같이 구성된 본 고안은 제2도 (a)에서와 같이 레스트렌트바(1)를 상승시키면 레스트렌트바(1)의 끝단에 연결된 푸쉬케이블(2)이 아암(3)의 한측을 잡아 당겨주게 되면 아암(3)이 중심회전으로 양측에 연결된 링크(4)을 밀어주고 링크(4)에 연결된 작동핀(5)이 외부로 돌출된 상태가 되어 작동핀(5)상에 위치한 붐(7)이 부주의 또는 유압라인의 파손으로 하강되어도 돌출된 작동핀(5)이 받쳐주기 때문에 붐(7)의 하강을 막아주게 된다.The present invention configured as described above, if the riser bar (1) is raised as shown in FIG. 2 (a) when the push cable (2) connected to the end of the restrent bar (1) pulls one side of the arm (3) The arm (3) pushes the link (4) connected to both sides in the center rotation and the actuating pin (5) connected to the link (4) is protruded outward so that the boom (7) located on the actuating pin (5) is The lowering of the boom 7 is prevented because the working pin 5 protrudes even if the lowering is caused by carelessness or damage of the hydraulic line.
붐(7)을 하강시킬 경우에는 상기의 역순작동으로 해제시키게 된다. 즉, 제2도 (b)에서와 같이 레스트렌트바(1)를 하강시키게 되면 푸쉬케이블(2)이 아암(3)을 밀어 주어 아암(3)의 중심회전으로 링크(4)를 잡아당기어 돌출된 작동핀(5)이 내입되어져 붐(7)이 하강하게 되는 것이다.When the boom 7 is lowered, the boom 7 is released by the reverse operation. That is, when the rest rent bar 1 is lowered as shown in FIG. 2 (b), the push cable 2 pushes the arm 3 to pull the link 4 in the center rotation of the arm 3. Protruding actuating pins 5 are embedded so that the boom 7 is lowered.
이상과 같이 본 고안은 부주의로 인해 붐 작동패달이 작동되거나 유압라인의 손상으로 붐을 하강되는 경우가 발생되어도 붐의 하강을 방지할 수 있게 됨으로서 안전한 정비작업을 수행하게 되는 효과가 있다.As described above, the present invention can prevent the lowering of the boom even when the boom operation pedal is inadvertently activated or the boom is lowered due to damage to the hydraulic line.
