Description

건설기계의 스윙 로킹장치Swing Locking Device of Construction Machinery
본 발명은 건설기계의 스윙 로킹장치에 관한 것으로, 특히 운전자가 캐빈 내부에서 스윙장치를 로킹시키는 로킹장치의 로킹 여부(swing lock 또는 swing unlock 상태)를 확인하거나 이를 조작할 수 있도록 한 건설기계의 스윙 로킹장치에 관한 것이다.The present invention relates to a swing locking device for a construction machine, and more particularly, a swing of a construction machine that enables a driver to check or manipulate a locking device (swing lock or swing unlock state) of a locking device for locking a swing device in a cabin. It relates to a locking device.
일반적으로, 주행 및 스윙이 가능한 굴삭기를 이용하여 중량체의 송유관 등을 매설하거나 또는 송유관 등을 인양하여 매설 장소로 운반하게 되는 파이프 레잉(pipe laying) 작업을 하게 된다. 이때 송유관 등을 와이어 로프에 의해 인양한 상태에서 주행하는 도중에, 운전자가 스윙장치 오조작으로 인해 상부 선회체를 급 선회시킬 경우, 관성에 의해 인양물이 장비의 선회 방향으로 흔들리게 된다. 이로 인해 장비와 송유관이 접촉되는 사고가 발생되거나, 와이어 로프로부터 인양물이 이탈되는 등의 심각한 안전사고 발생을 초래할 수 있게 된다.In general, a pipe laying work is carried out using an excavator that can travel and swing to bury an oil pipe of a heavy body, or to lift an oil pipe and carry it to a buried site. At this time, if the driver suddenly turns the upper swing structure due to the wrong operation of the swing device while driving the oil pipe or the like by the wire rope, the salvage is shaken in the turning direction of the equipment by the inertia. This can lead to serious safety accidents such as accidents in which the equipment and oil pipelines come into contact, or salvage from the wire rope.
전술한 바와 같이 운전자에 의한 스윙장치 오조작으로 인해 안전사고 발생을 방지할 수 있도록, 상부 선회체를 선회시키는 스윙장치를 구성하는 링기어에 대해, 별도의 스윙장치 로킹용 링기어(ring gear)를 체결함에 따라, 스윙장치 오조작으로 인한 안전사고 발생을 줄일 수 있게 된다.As described above, a ring gear for locking a separate swing device for a ring gear constituting a swing device that swings the upper swing body so as to prevent the occurrence of a safety accident due to a misoperation of a swing device by a driver. By tightening, it is possible to reduce the occurrence of safety accidents due to the wrong operation of the swing device.

There is a need for extra worker assistance. In addition, when the swing device locking ring gear is locked to the swing device to lock the swing device, it is impossible to confirm whether the swing device locking ring gear is completely locked to the swing device side ring gear.
또한, 상기 스윙장치 로킹용 링기어의 강도가 약할 경우에, 스윙장치가 로킹된 상태에서 운전자의 오조작으로 인해 무리하게 스윙시킬 경우 스윙 압력에 의해 링기어가 파손될 수 있는 문제점을 갖는다.In addition, when the strength of the ring gear for locking the swing device is weak, the ring gear may be damaged by the swing pressure when the swing device is forcibly swinged due to an incorrect operation of the driver in the locked state.
따라서 본 발명은 전술한 문제점을 해결하고자 하는 것으로, 운전자가 캐빈 내부에서 스윙장치를 로킹시키는 로킹장치의 로킹 여부를 확인한 후 스윙장치를 조작할 수 있도록 한 건설기계의 스윙 로킹장치를 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a swing locking device for a construction machine that allows a driver to operate a swing device after checking whether a locking device for locking the swing device in a cabin is locked.

도면중 미 설명부호 22는 주행장치(주행모터, 트랙 등을 포함)가 장착되며, 스윙장치에 의해 상부 선회체가 선회 가능하게 탑재되는 하부 프레임(lower frame)이다.In the drawing, reference numeral 22 denotes a lower frame on which a traveling device (including a driving motor, a track, etc.) is mounted and on which the upper swing body is pivotably mounted by a swing device.
전술한 구성에 따르면, 캐빈 내의 운전자에 의해 상기 스윙 락 스위치(17)를 조작할 경우 이의 조작신호가 제어부(19)에 출력된다. 상기 제어부(19)로부터의 제어신호에 의해 제어밸브(유압펌프(미 도시됨)로부터 액츄에이터(12)에 공급되는 작동유 흐름 방향을 제어하는 밸브임)를 절환시킴에 따라, 유압펌프로부터 공급되는 작동유에 의해 액츄에이터(12)를 신장구동시켜 로킹기어(11)를 스윙장치 로킹용 링기어(10)에 인게이지시킨다. 이때 액츄에이터(12)의 구동으로 인해 로킹기어(11)가 스윙장치 로킹용 링기어(10)에 인게이지될 경우, 상기 제3센서(15)에 의해 스윙장치 로킹용 링기어(10)와 로킹기어(11)가 인게이지된 스윙 락(swing lock) 상태를 검출하게 되며, 검출신호는 제어부(19)에 출력된다.According to the above-described configuration, when the swing lock switch 17 is operated by the driver in the cabin, its operation signal is output to the control unit 19. The hydraulic oil supplied from the hydraulic pump is switched by switching a control valve (which is a valve for controlling the hydraulic oil flow direction supplied from the hydraulic pump (not shown) to the actuator 12) by the control signal from the controller 19. The actuator 12 is extended and driven to engage the locking gear 11 with the ring gear 10 for locking the swing device. At this time, when the locking gear 11 is engaged by the ring gear 10 for locking the swing device due to the driving of the actuator 12, the locking device 10 and the swing gear locking ring 10 are locked by the third sensor 15. The gear 11 detects a swing lock state in which the gear 11 is engaged, and a detection signal is output to the controller 19.
또한, 상기 로킹기어(11)를 기준으로 좌우 대칭되게 설치된 상기 얼라인먼트 셋팅여부를 확인하는 제1,2센서(13,14)에 의해 스윙장치 로킹용 링기어(10)와 로킹기어(11)의 얼라인먼트 상태를 검출하게 되며, 검출신호는 제어부(19)에 출력된다. 이로 인해 제어부(19)는 상기 스윙장치 로킹용 링기어(10)와 로킹기어(11)가 이맞물림 완료된 경우, 상기 스윙장치 로킹용 링기어(10)와 로킹기어(11)의 얼라인먼트 셋팅 완료상태를 캐빈 내의 운전자에게 지시램프(21)(일 예로서 led가 사용될 수 있음)의 점등을 통해 알려주게 된다. 또한 제어부(19)는 스윙장치의 스윙 락 및 스윙 언락용 솔레노이드밸브(20)(전기적 제어신호 입력에 따라 절환되어 스윙장치의 스윙모터에 공급되는 작동유 흐름 방향을 제어하는 밸브임)에 인가되는 전원을 오프(off) 상태로 전환하게 된다.In addition, the swing gear locking ring gear 10 and the locking gear 11 by the first and second sensors 13 and 14 which check whether the alignment setting is installed symmetrically with respect to the locking gear 11. The alignment state is detected, and the detection signal is output to the controller 19. Therefore, when the swing device locking ring gear 10 and the locking gear 11 are engaged with each other, the control unit 19 completes the alignment setting of the swing device locking ring gear 10 and the locking gear 11. The driver in the cabin is informed through the lighting of the indicator lamp 21 (led may be used as an example). In addition, the control unit 19 is a power applied to the swing lock and swing unlock solenoid valve 20 of the swing device (which is a valve for controlling the flow direction of the hydraulic oil supplied to the swing motor of the swing device is switched in accordance with the input of the electrical control signal) Will be turned off.
따라서, 운전자에 의해 주행장치용 조작레버(미 도시됨)를 조작하여 장비를 전,후진시켜 주행할 수 있다. 반면에 스윙장치 로킹용 링기어(10)와 로킹기어(11)가 인게이지되어 로킹된 상태이므로, 스윙장치의 스윙모터에 공급되는 작동유를 제어하는 스윙 락 및 스윙 언락용 솔레노이드밸브(20)에 제어부(19)로부터 인가되는 전원이 차단되어 장비를 선회시킬 수 없게 된다. 즉 상기 액츄에이터(12)의 구동으로 인해 스윙장치 로킹용 링기어(10)로부터 로킹기어(11)를 디스인게이지시켜 언락 상태로 전환시킬 경우에도, 상기 제4센서(16)에 의해 스윙장치 로킹용 링기어(10)에 대한 로킹기어(11)의 언락 상태를 검출하는 검출신호가 제어부(19)에 출력되지않을 경우에는, 스윙장치 로킹용 링기어(10)와 로킹기어(11)의 락이 해제되지않은 것으로 판단하게 된다. 이로 인해 운전자에 의해 상부 선회체를 선회시키기 위해 스윙장치용 조작레버(미 도시됨)를 조작하는 경우 스윙장치는 작동되지않아 상부 선회체는 선회되지 않게 된다.Therefore, the driver may operate the operation lever for the traveling device (not shown) to move the equipment forward and backward. On the other hand, since the swing gear locking ring gear 10 and the locking gear 11 are engaged and locked, the swing lock and swing unlock solenoid valve 20 controls the hydraulic oil supplied to the swing motor of the swing gear. Power applied from the control unit 19 is cut off so that the equipment cannot be turned. That is, even when the locking gear 11 is disengaged from the ring gear 10 for swing device locking due to the driving of the actuator 12 to switch to the unlocked state, the swing device locking is performed by the fourth sensor 16. When the detection signal for detecting the unlocked state of the locking gear 11 with respect to the ring gear 10 is not output to the control unit 19, the lock of the swing device locking ring gear 10 and the locking gear 11 is locked. It is determined that it has not been released. As a result, when the swing lever operating lever (not shown) is operated by the driver to swing the upper swing body, the swing device is not operated and the upper swing body is not turned.
한편, 운전자에 의해 상기 스윙 언락 스위치(18)를 조작하는 경우 조작신호가 제어부(19)에 출력된다. 이로 인해 상기 제어부(19)로부터의 제어신호에 의해 액츄에이터(12)를 수축구동시켜 로킹기어(11)를 스윙장치 로킹용 링기어(10)로부터 디스인게이지시킨다. 이때 액츄에이터(12)의 수축구동으로 인해 로킹기어(11)가 스윙장치 로킹용 링기어(10)로부터 디스인게이지될 경우, 상기 제4센서(16)에 의해 스윙장치 로킹용 링기어(10)와 로킹기어(11)가 디스인게이지된 스윙 언락(swing unlock) 상태를 검출하게 되며, 검출신호는 제어부(19)에 출력된다.On the other hand, when operating the swing unlock switch 18 by the driver, the operation signal is output to the control unit 19. Accordingly, the actuator 12 is contracted and driven by the control signal from the controller 19 to disengage the locking gear 11 from the swing device locking ring gear 10. At this time, when the locking gear 11 is disengaged from the swing gear locking ring gear 10 due to the contraction driving of the actuator 12, the swing gear locking ring gear 10 is driven by the fourth sensor 16. And the locking gear 11 detects a swing unlocked state in which the disengaged swing is performed, and a detection signal is output to the controller 19.
또한, 상기 얼라인먼트 셋팅여부를 확인하는 제1,2센서(13,14)에 의해 스윙장치 로킹용 링기어(10)와 로킹기어(11)의 디스인게이지 상태를 검출하게 되며, 검출신호는 제어부(19)에 출력된다. 이로 인해 제어부(19)는 상기 스윙장치 로킹용 링기어(10)와 로킹기어(11)가 디스인게이지된 상태로 판단하게 되며, 상기 스윙장치 로킹용 링기어(10)와 로킹기어(11)의 디스인게이지된 상태를 캐빈 내의 운전자에게 지시램프(21)의 소등을 통해 알려주게 된다. 또한 제어부(19)는 스윙장치의 스윙 락 및 스윙 언락용 솔레노이드밸브(20)에 인가되는 전원을 온(on) 상태로 전환하게 된다.In addition, the first and second sensors 13 and 14 which check whether the alignment is set are detected by the disengage state of the swing gear locking ring gear 10 and the locking gear 11, and the detection signal is controlled by the control unit. It is output to (19). As a result, the control unit 19 determines that the swing gear locking ring gear 10 and the locking gear 11 are disengaged, and the swing gear locking ring gear 10 and the locking gear 11. The disengaged state of the driver is notified by turning off the indicator lamp 21 to the driver in the cabin. In addition, the control unit 19 is to turn on the power applied to the swing lock and swing unlock solenoid valve 20 of the swing device (on).
따라서, 운전자에 의해 주행장치용 조작레버를 조작하여 장비를 주행할 수 있게 된다. 또한 스윙장치의 스윙모터에 공급되는 작동유를 제어하는 스윙 락 및 스윙 언락용 솔레노이드밸브(20)에 전원이 인가되어 절환시킬 경우, 유압펌프로부터 스윙모터에 공급되는 작동유에 의해 스윙장치를 구동시켜 상부 선회체를 선회시킬 수 있게 된다.Therefore, it is possible to drive the equipment by operating the operation lever for the traveling device by the driver. In addition, when power is applied to the swing lock and the swing-unlock solenoid valve 20 for controlling the hydraulic oil supplied to the swing motor of the swing device, the swing device is driven by the hydraulic oil supplied from the hydraulic pump to the swing motor. It is possible to turn the swinging structure.
전술한 바와 같이 캐빈 내부에서 운전자는 스윙장치 로킹용 링기어(10)와 로킹기어(11)의 인게이지 또는 디스인게이지되는 얼라인먼트 상태를 지시램프 등을 통하여 확인할 수 있어 편리하다. 또한 파이프 레잉 작업을 하는 경우에, 운전자 부주의로 인해 스윙장치를 오조작하는 경우에도 장비는 선회되지않게 되므로 중량체의 송유관 등의 움직임으로 인한 안전사고 발생을 방지할 수 있다.As described above, in the cabin, the driver can conveniently check the alignment state of the ring gear 10 for locking the swing device and the locking gear 11 through the indicator lamp or the like. In addition, in the case of pipe laying work, even if the swing device is mishandled due to the driver's carelessness, the equipment does not turn, thereby preventing the occurrence of a safety accident due to the movement of a heavy oil pipeline.
여기에서, 상술한 본 발명에서는 바람직한 실시예를 참조하여 설명하였지만, 해당 기술분야에서 숙련된 당업자는 하기의 특허청구범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경할 수 있음을 이해할 수 있을 것이다.Herein, while the present invention has been described with reference to the preferred embodiments, those skilled in the art will variously modify the present invention without departing from the spirit and scope of the invention as set forth in the claims below.
