본 고안은 유압식삽과 같은 건설기계의 작업 유니트 작동을 제어하는 건설기계용 제어 유니트에 관한 것이다.The present invention relates to a control unit for a construction machine that controls the operation of the work unit of a construction machine such as a hydraulic shovel.
일반적으로 공지된 바와같이, 예를들면, 유압식삽은 유압식삽의 작업유니트 제어를 용이하게 하기 위하여 종횡 방향의 피벗운동을 위한 피벗식으로 지지된 한개의 제어레버를 가진 제어유니트를 구비하고 있다.As is generally known, for example, a hydraulic shovel is provided with a control unit having one control lever pivotally supported for longitudinal and horizontal pivoting movements to facilitate control of the work unit of the hydraulic shovel.
제어레버는 아암을 제어하기 위해서 종방향 즉 전후 방향으로 바뀌고 버키트 (bucket)을 제어하기 위해서는 횡방향, 즉 좌우방향으로 바뀐다.The control lever is shifted in the longitudinal direction, ie front and rear, to control the arm, and in the transverse direction, ie, left and right, to control the bucket.
이와같이 공지된 제어레버는 제5도 및 제6도를 참조하여 기술될 것이다.Such a known control lever will be described with reference to FIGS. 5 and 6.
제어레버(1)는 종횡방향의 피벗 운동용 유니버셜 커플링기구(2)에 의해서 도시되어 있지 않은 고정레버대 위에서 지지된다.The control lever 1 is supported on a stationary lever stand, not shown, by the universal coupling mechanism 2 for longitudinal movement in the longitudinal direction.
브래킷(3)은 제어레버(1)와 일체적으로 피벗에 놓이기 위해서 제어레버(1) 하단에 브래킷(3)을 가압하는 너트(4)로 제어레버(1)하단에 체결된다.The bracket 3 is fastened to the bottom of the control lever 1 with a nut 4 that presses the bracket 3 to the bottom of the control lever 1 in order to be integrally pivoted with the control lever 1.
너트(4)가 느슨하게 풀어질때에 브래킷(3)은 제어레버(1)축에 대하여 회전할 수 있다.When the nut 4 is loosened, the bracket 3 can rotate about the control lever 1 axis.
제1유압식 실린더 액츄에이터 작동을 제어하기 위한 제1유압식 제어밸브(5)를 작동하는, 예를들면, 유압식 삽의 아암을 작동하는 제1링크로드(6)상단, 그리고 제2유압식 실린더 액츄에이터 작동을 제어하기 위한 제2유압식 제어밸브(7)를 작동하는, 예를들면 유압식 삽의 버키트 작동을 하는 제2링크로드 상단은 원주방향으로 90°각도 간격으로 떨어진 위치에 각각 브래킷(3)에 연결되어 있다.To operate the first hydraulic control valve 5 for controlling the operation of the first hydraulic cylinder actuator, for example, on top of the first link rod 6 for operating the arm of the hydraulic shovel, and for the operation of the second hydraulic cylinder actuator. The upper end of the second link rod, which operates the second hydraulic control valve 7 for controlling, for example, the bucket operation of the hydraulic shovel, is connected to the bracket 3 at positions spaced at 90 ° intervals in the circumferential direction. It is.
단지 제1링크로드(6)만이 제어레버(1)가 제1유압식 제어밸브(5)를 작동하기 위해서 전후 방향으로 바뀔때 당겨지거나 또는 밀려진다.Only the first link rod 6 is pulled or pushed when the control lever 1 changes back and forth to operate the first hydraulic control valve 5.
단지 제2링크로드(8)만이 제어레버(1)가 제2유압식 제어밸브(7)을 작동하기 위해서 좌우방향으로 바뀔때 당겨지거나 또는 밀려진다.Only the second link rod 8 is pulled or pushed when the control lever 1 is turned left and right to operate the second hydraulic control valve 7.
어떤 경우에는 예를들면, 제어레버(1)를 전후방향으로 바꾸므로써 버키트를 작동시키는 제어작동모우드로부터 제어레버(1)를 동일한 방향으로 바꾸므로써 아암을 작동시키는 또 다른 제어작동 모우드로 제어작동 모우드를 변경하도록 제어유니트의 셋업을 변경하는 것이 바람직스럽다.In some cases, for example, control operation from the control operation mode for operating the bucket by changing the control lever 1 in the front-rear direction and the control operation with another control operation mode for operating the arm by changing the control lever 1 in the same direction. It is desirable to change the setup of the control unit to change the mode.
이와같은 경우에, 너트(4)를 풀어 브래킷(3)을 느슨하게하여 브래킷(3)을 의도하는 방향으로 90°회전한후 너트(4)로 브래킷(3)을 제어레버(1)에 다시 체결한다.In this case, loosen the nut (4), loosen the bracket (3), rotate the bracket (3) by 90 ° in the intended direction, and then fasten the bracket (3) to the control lever (1) again with the nut (4). do.
상기의 제어유니트 셋업 변경 방법은 브래킷(3)을 풀기 위해 스패너로서 너트 (4)를 풀어야하고 다시 브래킷(3)을 제어레버(1)에 체결하기 위해 스패너로 너트 (4)를 체결하는 귀찮은 작업이 필요하다.The above control unit setup change method is a cumbersome task of loosening the nut 4 as a spanner to loosen the bracket 3 and tightening the nut 4 with a spanner to fasten the bracket 3 to the control lever 1 again. This is necessary.
그러므로, 본 고안은 의도하는 제어작동 모우드를 위하여 어떤 셋업으로 부터 또 다른 셋업으로 간단히 그리고 신속하게 변경할 수 있는 구조를 가진 건설기계용 제어 유니트를 목적으로 하고있다.Therefore, the present invention aims at a control unit for a construction machine with a structure that can be changed simply and quickly from one setup to another for the intended control operation mode.
본고안의 한면에 있어서, 건설기계용 제어유니트는 종횡방향운동을 위해서 피벗으로 지지된 제어레버, 제어레버가 종횡방향중 한방향으로 바뀔때 제어레버 작동력을 제1유압식 제어밸브에 전달하기 위한 제1링크로드, 그리고 제어레버가 다른 방향으로 바뀔때 제어레버 작동력을 제2유압식 제어밸브에 전달하는 제2링크로드로 구성되어 있으며, 관형 작동력 전달부 부재는 제어레버축에 대하여 회전될 수 있도록 제어레버위에 놓여져 있으며, 제1, 제2링크로드의 각각은 상단은 제어레버축에 대하여 각각 90°간격으로 떨어져 일정한 간격을 유지하는 지점에서 작동력 전달부재와 각각 피벗으로 연결되어 있으며, 고정식부재(locking member)는 작동력전달부재로부터 맞물림 단속을 위해서 제어레버축을 따라 움직여질수 있고 그리고 제어레버에 대하여 회전을 억제하도록 작동력 전달부재위에 있는 제어레버위에 놓여지며, 작동력 전달부재와 고정부재의 맞물리는 부분은 마찰면(facet)을 가지고 있으므로 작동력 전달부재는 고정부재가 작동력 전달부재와 맞물려질때 제어레버 축선에 대하여 90°간격으로 떨어져 일정한 간격을 유지하는 두 지점에서 제어레버에 대한 회전을 억제하는 것을 특징으로 한다.In one aspect of the present invention, a control unit for construction machinery includes a control lever pivotally supported for longitudinal movement, and a first link for transmitting control lever actuation force to the first hydraulic control valve when the control lever is changed to one of the longitudinal and transverse directions. The rod and the second link rod for transmitting the control lever actuation force to the second hydraulic control valve when the control lever is changed in the other direction, the tubular actuation force transmission member is placed on the control lever so that it can be rotated about the control lever shaft. Each of the first and second link rods is pivotally connected to the actuation force transmitting member at a point at which the upper end is spaced apart by 90 ° with respect to the control lever shaft and maintained at a constant distance, respectively. Can be moved along the control lever shaft for intermittent engagement from the operating force transmitting member and rotated relative to the control lever It is placed on the control lever on the actuation force transmitting member to suppress the pressure. The engaging portion of the actuation force transmitting member and the fixing member has a facet, so the actuation force transmitting member is placed on the control lever axis when the fixing member is engaged with the actuation force transmitting member. It is characterized by suppressing the rotation of the control lever at two points spaced apart by 90 ° to maintain a constant interval.
제어작동 모우드 변경에 있어서, 제어유니트 셋업은 다음 순서에 의해 변경된다.In changing the control operation mode, the control unit setup is changed by the following procedure.
1. 고정식부재는 작동력 전달부재로부터 고정식부재를 맞물리지 않도록 제어레버를 따라 움직여짐으로써, 작동력 전달부재는 제어레버 축에 대하여 회전할 수 있도록 한다.1. The stationary member is moved along the control lever so as not to engage the stationary member from the actuation force transmitting member so that the actuation force transmitting member can rotate about the control lever axis.
2. 작동력 전달부재는 제어레버에 대한 위치를 변경하기 위해 90°로 회전한다.2. The actuation force transmitting member rotates by 90 ° to change its position with respect to the control lever.
3. 고정식 부재는 새로운 위치에서 작동력 전달부재를 소정시키기 위해서 작동력 전달부재와 맞물리게 한다.3. The stationary member is engaged with the actuation force transmission member to define the actuation force transmission member in a new position.
따라서 제어유니트의 셋업은 작동력 전달부재를 제어레버에 고정시키고 또한 제어레버에 대하여 자유로운 회전을 위해 작동력 전달부재를 단순히 축방향으로 고정식부재를 바꾸므로써 제어작동 모우드를 변경하는데는 간단히 그리고 신속하게 변경될 수 있다.Therefore, the setup of the control unit is simple and quick to change the control operation mode by fixing the actuation force transmitting member to the control lever and simply changing the actuation force transmitting member in the axial direction for free rotation with respect to the control lever. Can be.

Each is connected with the link rod support 15a.
제어레버(11)에 작용한 작동력은 제어레버(11)작동방향에 따라 각각의 유압식 제어밸브(16 또는 18)을 작동하기 위해서 전달부재(15)을 통해 각각 링크로드(17 또는 19)로 전달된다.The actuation force acting on the control lever 11 is transmitted to the link rod 17 or 19 through the transfer member 15 to operate the respective hydraulic control valve 16 or 18 according to the control lever 11 operating direction. do.
제어유니트가 제1도에서와 같이 셋업될때, 제1링크로드(17)는 제어레버가 전후방향으로 바뀔때 제1유압식 제어밸브(16)을 작동하기 위하여 밀리거나 또는 당겨지며, 제2링크로드(19)는 제어레버가 앞뒤방향으로 바뀔 때 제1유압식 제어밸브(18)을 작동하기 위하여 밀리거나 또는 당겨진다.When the control unit is set up as in FIG. 1, the first link rod 17 is pushed or pulled to operate the first hydraulic control valve 16 when the control lever is turned back and forth, and the second link rod 19 is pushed or pulled to operate the first hydraulic control valve 18 when the control lever is turned back and forth.
제4도에서 도시한 제어유니트의 셋업은 제1도에서 도시한 바와같이 제어레버 (11)축선에 대하여 90°각도로 시계반대방향으로 전달부재(15)을 회전시킴으로써 조절된다.The setup of the control unit shown in FIG. 4 is adjusted by rotating the transmission member 15 counterclockwise at an angle of 90 ° with respect to the control lever 11 axis as shown in FIG.
제4도에서 도시된 셋업에서, 제2유압식 제어밸브(18)는 종방향으로 제어레버 (11)을 바꾸므로써 작동되고, 제1유압식 제어밸브(16)는 횡방향으로 제어레버(11)을 바꾸므로서 작동된다.In the setup shown in FIG. 4, the second hydraulic control valve 18 is operated by changing the control lever 11 in the longitudinal direction, and the first hydraulic control valve 16 moves the control lever 11 in the transverse direction. It works by changing.
칼라(Collar)(20)는 전달부재(15)상단에 단단히 부착되어 있다. 둥근 그립 (grip)부분(20a)은 칼라(20)중간 하단에 있다.The collar 20 is firmly attached to the upper end of the transfer member 15. A round grip portion 20a is at the bottom bottom of the collar 20.
그립부분(20a)의 외면은 확실히 잡을 수 있도록 오목볼록하게 되어 있다.The outer surface of the grip portion 20a is concave and convex so as to securely grasp.
사각형 연동식 부분(inter locking portion)(20b)은 칼라(20) 중간 상단에 있다.A rectangular inter locking portion 20b is at the upper middle of the collar 20.
전달부재(15)는 칼라(20)의 그립부분(10s)을 파지함에 의해서 제어레버(11)축 중심으로 회전시킬 수 있다.The transmission member 15 can be rotated about the control lever 11 axis by holding the grip portion 10s of the collar 20.
직각고형 중간 블록(21)은 칼라(20)위의 제어레버(11)에 놓여지고 핀(22)으로 고정되어 있다.The rectangular solid block 21 is placed on the control lever 11 on the collar 20 and fixed with pins 22.
중간블록(21)의 면적은 칼라(20)의 연동식부분(20b)의 면적과 동일하다.The area of the intermediate block 21 is equal to the area of the interlocked portion 20b of the collar 20.
관형 연동식부재(23)는 중간블록(21)과 칼라(20)의 연동식부분(20b)위로 뻗기 위해서 축선방향으로 미끄러질 수 있게 제어 레버(11)에 놓여진다.The tubular interlocking member 23 is placed on the control lever 11 so as to slide in the axial direction in order to extend over the interlocking portion 20b of the intermediate block 21 and the collar 20.
칼라(20)의 연동식부분(20b)과 중간블록(21)에 맞는 사각형 오목부가 있는 소켓트 부재(23a)는 연동식부재(23)의 하단 절반부에 있다.A socket member 23a having a rectangular recess to fit the interlocking portion 20b of the collar 20 and the intermediate block 21 is at the lower half of the interlocking member 23.
중간블록(21)과 칼라(20)의 연동식부분(20b)을 연동식부재(23)의 소켓트부재(23a)의 사각형오목부에 수용된다.The interlocking portion 20b of the intermediate block 21 and the collar 20 is accommodated in the rectangular recess of the socket member 23a of the interlocking member 23.
실링부재(24)는 조정레버(11)과 연동식부재(23)사이의 유격을 밀폐시켜주기 위해서 연동식부재(23)상단 내면에 형성된 환상형 홈에 수용된다.The sealing member 24 is accommodated in an annular groove formed on the inner surface of the upper end of the interlocking member 23 in order to seal the clearance between the adjustment lever 11 and the interlocking member 23.
칼라(20)의 연동식부분(20b)과 중간블록(21)이 연동식부재(23)의 소켓트부재(23a)의 사각형 오목부에 수용된 상태에서는 중간블록(21), 연동식부재(23) 및 칼라(20)는 제어레버(11)에 대하여 회전할 수 없으므로, 전달부재(15)는 제어레버(11)에 대하여 회전하지 못하게 된다.The intermediate block 21 and the interlocking member 23 in a state where the interlocking portion 20b of the collar 20 and the intermediate block 21 are accommodated in the rectangular recesses of the socket member 23a of the interlocking member 23. ) And the collar 20 cannot rotate with respect to the control lever 11, so that the transmission member 15 cannot rotate with respect to the control lever 11.
제1도에서 도시된 셋업을 제4도에서 도시된 셋업으로 변경할때는 연동식부재 (23)는 소켓트부재(23a)를 칼라(20)의 연동식부분(20b)으로부터 분리하기 위해서 상방으로 옮겨진다. 그러면, 칼라(20), 그러므로 전달부재(15)는 제어레버(11)에 대하여 회전할 수 있다.When changing the setup shown in FIG. 1 to the setup shown in FIG. 4, the interlocking member 23 moves upward to separate the socket member 23a from the interlocking portion 20b of the collar 20. Lose. Then, the collar 20 and therefore the transmission member 15 can rotate relative to the control lever 11.
전달부재(15)는 전달부재(15)을 제4도에서 도시된 위치로 놓기 위해서 칼라(20)의 그립부분(20a)을 파지함에 의해서 90°각도를 통해서 회전된다.The transfer member 15 is rotated through an angle of 90 ° by holding the grip portion 20a of the collar 20 to place the transfer member 15 in the position shown in FIG.
그래서 연동식부재(23)는 전달부재(15)을 레버(11)에 대하여 회전되지 못하도록 제2도에서 도시된 최초의 위치로 되돌아간다.The interlocking member 23 then returns to the initial position shown in FIG. 2 to prevent the transmission member 15 from rotating relative to the lever 11.
칼라(20)의 연동식부분(20b)이 본실시예에서 연동식부재(23)의 소켓트부재 (23a)에 수용될지라도, 연동식부재(23)의 소켓트 부재(23a)는 칼라(20)의 연동식부분(20b)에 수용된다.Although the interlocking portion 20b of the collar 20 is accommodated in the socket member 23a of the interlocking member 23 in this embodiment, the socket member 23a of the interlocking member 23 is a collar ( 20 is received in the interlocked portion 20b.
후자의 경우에 소켓트부재(23a)의 외면과 연동식부분(20b)의 내면은 실제적으로 동일한 사각단면으로 되어 있다.In the latter case, the outer surface of the socket member 23a and the inner surface of the interlocking portion 20b are substantially the same rectangular cross section.
더구나, 소켓트 부재(23a)와 연동식부분(20b)은 결합부분면이 필수적으로 단지 형성되므로서 칼라(20), 그러므로 전달부재(15)는 서로 90°간격으로 떨어진 두지점에서 연동식부재(23), 즉 제어레버(11)에 대하여 회전하지 못하기 때문에, 본 제어 유니트는 예를들면, 서로 수직으로 교차하는 2개의 마찰면을 가지는 암부분을 가진 소켓트부재 그리고 90°간격으로 형성된 3개의 마찰면을 가진 숫부분을 가진 플러그 부재를 구비하고 있다.Moreover, the collar member 23a and the interlocking portion 20b are interlocked members at two points separated from each other by 90 °, so that the collar 20, and therefore the transmission member 15, are essentially formed only with the mating surface. (23), i.e., because it does not rotate relative to the control lever 11, the control unit is formed with, for example, a socket member having a female portion having two friction surfaces perpendicularly intersecting with each other and a 90 ° interval. A plug member having a male portion with three friction surfaces is provided.
상기 설명으로부터 제어레버(11)와 유압식제어밸브(16,18)에 대한 전달부재 (15)의 각 위치는 연동식부재(23)를 제어레버(11)을 따라 미끄러지게 함에 의해서 간단히 연동식부재(23)을 전달부재에 부착된 칼라(20)의 연동식(20b)으로부터 맞물리지 않게하고, 전달부재(15)와 칼라(20)를 제어레버(11)축에 대하여 90°까지 회전시키고, 그리고 연동식부재(23)을 다시 칼라(20)의 연동식부분(20b)에 맞물림시킴에 의해서 쉽게 변경될 수 있다.From the above description, each position of the transmission member 15 relative to the control lever 11 and the hydraulic control valves 16 and 18 is simply interlocked by sliding the interlocking member 23 along the control lever 11. The 23 is not engaged from the interlocking type 20b of the collar 20 attached to the transmission member, the transmission member 15 and the collar 20 are rotated by 90 ° with respect to the control lever 11 axis, and It can be easily changed by engaging the interlocking member 23 again with the interlocking portion 20b of the collar 20.
그래서 본 제어유니트의 셋업 변경을 하기 위한 작동은 너트를 작동하여 제어레버로부터 브래킷을 풀고 다시 부착하는 공지 공용된 제어 유니트의 셋업 변경보다 더 간단히 그리고 신속하게 이루어진다.Thus, the operation for making a setup change of the control unit is made simpler and faster than the setup change of a known and common control unit which actuates the nut to release and reattach the bracket from the control lever.
본 고안이 바람직한 형태로만 설명되어졌을지라도 분명하게 많은 변경과 변동이 본 발명의 범위내에서 가능하다. 그러므로 본 고안은 본 고안의 정신과 범위를 벗어나지 않고 여기에서 특별히 개시한 것 이외에도 실시가 가능하다는 것은 이해하여야만 한다.Obviously many modifications and variations are possible within the scope of the invention even if the invention has been described in its preferred form. Therefore, it is to be understood that the present invention may be practiced other than as specifically disclosed herein without departing from the spirit and scope of the present invention.
