본 고안은 유압식 굴삭기 등의 중장비 조정레버 중립 록킹 장치에 관한 것이다.The present invention relates to a heavy equipment adjustment lever neutral locking device such as a hydraulic excavator.

종래 일반적인 중장비의 조정레버는 운전석 좌우측에 요동이 가능하도록 설치하고 있으나 이들은 별도의 안전장치가 설치되어 있지 않기 때문에 운전자가 운전석에서 이탈하거나 혹은 운전석 내에서 다른 행동을 하는 경우에 운전자의 옷이나 신체부위가 조정레버에 접촉하는 등 사소한 부주위에 의하여 요동되어 이에 따른 중장비의 예기치 못한 작동에 의해 안전사고가 발생하되 사례가 종종있게 되는 것이다.Conventionally, the adjustment levers of general heavy equipment are installed to allow swinging on the left and right sides of the driver's seat, but since they are not equipped with a separate safety device, the driver's clothes or body parts when the driver leaves the driver's seat or performs other actions in the driver's seat. There is a case where a safety accident occurs due to unexpected operation of heavy equipment due to minor sub-circumference such as contacting the control lever.

따라서 본 고안은 이러한 종래에 문제점을 해결하기 위하여 중장비의 조정레버에 간단한 구조의 록킹 장치를 설치하여 미연에 사고를 방지할수 있도록 안출된 것으로서 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.Therefore, the present invention was conceived to prevent accidents in advance by installing a locking device of a simple structure in the adjustment lever of heavy equipment in order to solve such a conventional problem.

도시한 바와 같이 기체에 요동 가능하도록 설치된 조정레버(1)의 하단에 핀(2)으로 콘트롤밸브 스풀(control valve spoo1)(3)과 연결되어 콘트롤 밸브(4)를 작동시키는 통상의 중장비 유압계통에 있어서, 중공(中空)으로된 조정레버(1)에 전선 인출공(14)이 천공되고 그 외부측면에 솔레노이드(9)가 부착된 브라켓(11)이 고정되어 있으며, 솔레노이드(9)의 상부에는 솔레노이드축(10)이 삽입될 수 있도록 고정공(13)을 천공시킨 고정브라켓(12)을 형성시켰으며, 조정레버의 (1)상단에는 손잡이(5)를 장착시키되 손잡이(5) 상단 중앙에 공지의 푸시버튼 스위치(6)를 장착하여 전선(7)으로 솔레노이드(9)와 연결하여서 된 것이다.As shown in the figure, a conventional heavy-duty hydraulic system for connecting the control valve spoo1 3 to the control valve spoo1 3 with a pin 2 at the lower end of the adjustment lever 1 installed so as to oscillate to the gas to operate the control valve 4. In the hollow adjustment lever (1), the wire drawing hole (14) is drilled and the bracket (11) with the solenoid (9) attached to the outer side thereof is fixed, and the upper part of the solenoid (9) On the upper side of the adjusting lever (1), a handle (5) is mounted, and a handle (5) is mounted on the fixing bracket (12), so that the solenoid shaft (10) can be inserted therein. The well-known pushbutton switch 6 is attached to the solenoid 9 by the wire 7.

제 3 도는 본 고안의 회로로도로서 밧데리(B)의 일단은 차체에 접지되고 그 타단은 키 스위치(K)가 연결되며, 그 접속단에는 푸시버튼 스위치(6)를 연결하여 솔레노이드(9)의 일단과 연결하고 그 타단은 차체에 접지시킨 상태를 보여준다.3 is a circuit diagram of the present invention, one end of the battery (B) is grounded to the vehicle body and the other end thereof is connected to the key switch (K), the connection end of the solenoid (9) by connecting a pushbutton switch (6) It is connected to one end and the other end is grounded to the body.

이와 같이 구성된 본 고안은 운전 및 조정을 하는 경우에 운전자가 손잡이(5)를 잡는 것과 동시에 푸시버튼스위치(6)를 누르면 이에 연결된 전선(7)에 밧테리의 전류가 흘러 솔레노이드(9)를 작동시켜 솔레노이드축(10)이 고정브라켓(12)의 고정공(13)으로 부터 빠져나오게 되어 조정레버(1)를 작동시킬 수 있게 되는 것이며, 반대로 작업중단시에는 운전자가 손잡이(5)를 놓으면서 스위치(6)에 가한 힘을 해제하면 솔레노이드축(10)은 원위치로 복귀되면서 고정브라켓(12)의 고정공(13)에 삽입되어 조정레버(1)는 록크 상태가 되는 것이다.The present invention configured as described above allows the driver to hold the handle 5 and press the pushbutton switch 6 at the same time to operate the solenoid 9 by flowing a current of the battery to the wire 7 connected thereto. The solenoid shaft 10 is released from the fixing hole 13 of the fixing bracket 12 so that the adjustment lever 1 can be operated. On the contrary, when the operation stops, the driver releases the handle 5 and the switch ( When the force applied to 6) is released, the solenoid shaft 10 returns to its original position and is inserted into the fixing hole 13 of the fixing bracket 12 so that the adjustment lever 1 is locked.

즉, 본 고안은 조정레버(1)의 측면에 솔레노이드(9)를 부착하고 손잡이(5)상단에 공지의 푸시버튼 스위치(6)를 장착하여 간단한 동작으로 조정레버(1)를 록킹시킬 수 있고 또한 이를 해체하여 작업할 수 있는 것으로 부주의로 인한 외력이 조정레버(1)에 작용하더라도 중장비가 움직일염려가 없게 되어 안전사고를 미연에 방지할 수 있는 것이다.In other words, the present invention attaches the solenoid 9 to the side of the adjustment lever 1 and mounts a well-known pushbutton switch 6 on the handle 5 to lock the adjustment lever 1 with a simple operation. In addition, it is possible to dismantle it, and even if external force due to carelessness acts on the control lever (1), there is no risk of heavy equipment moving, thereby preventing safety accidents.

또 다른 실시예로서는 제 4 도에 도시된 바와 같이 솔레노이드(9)를 콘트롤밸브(4) 몸체에 장착하여 솔레노이드 축(10)이 콘트롤 밸브(4)의 스풀(3)에 마련된 정지홈 20에 끼워 질 수 있도록 함으로써, 조정레버(1)에 의해 동작되는 스풀(3)의 동작을 제한할 수 있도록 한 것이다.In another embodiment, as shown in FIG. 4, the solenoid 9 is mounted on the body of the control valve 4 so that the solenoid shaft 10 is fitted into the stop groove 20 provided in the spool 3 of the control valve 4. By making it possible, the operation of the spool 3 operated by the adjustment lever 1 can be limited.

다시 말해서, 동작은 상기의 본 고안과 동일하게 이루어지되, 다만 솔레노이드(9)를 콘트롤밸브(4)의 몸체에 장착하여 스풀(3)의 동작을 제한할수 있도록 함으로써 조정레버(1)의 동작을 제한할수 있도록한 것이다.In other words, the operation is made in the same manner as above, but the solenoid 9 is mounted on the body of the control valve 4 to limit the operation of the spool 3 so as to restrict the operation of the adjustment lever 1. It is to be limited.

이상과 같이 본 고안은 간단한 구조의 록킹장치를 설치하는 것으로 비작업 또는 운휴시에 조정레버를 로크시켜 예기치 않은 중장비의 움직임에 따른 안전사고를 확실하게 방지할수 있는 고안이다.As described above, the present invention is to install a locking device having a simple structure, and to prevent the safety accident due to unexpected movement of heavy equipment by locking the adjustment lever during non-working or non-operation.
