이와같은 종래의 중장비의 선택장치의 조작은 별도의 기계식 레버 및 스풀이 내장된 콘트롤 밸브에 의하여 이루어지는데, 이 경우 구성부품이 차지하는 운전실내의 공간이 적지 않고, 운전자의 레버 조작성의 면에서 불편하며, 복합작업시 조작레버2개(주작업장치용과 선택장치용)를 동시에 조작하기가 어려운 문제가 있었다.The operation of the conventional heavy equipment selection device is performed by a control valve with a separate mechanical lever and a spool. In this case, there is not much space in the cab occupied by components, and it is inconvenient in terms of the lever operability of the driver. In the case of complex work, it was difficult to simultaneously operate two operation levers (for the main work device and the selection device).

본 고안은 상기와 같은 제반 문제점을 해결하기 위하여 안출된 것으로, 전기식 스위치로 간단하게 선택장치를 조작하고 또한 주작업장치와 선택장치를 동시에 작업시킬 수 있도록 함으로써 장비의 조작성과 정비성을 향상시킬 수 있는 중장비 선택장치의 전기식 제어장치를 제공하는 것을 목적으로 한다.The present invention was devised to solve the above problems, and it is possible to improve the operability and maintainability of the equipment by simply operating the selection device with an electric switch and simultaneously working the main work device and the selection device. It is an object of the present invention to provide an electrical control device for a heavy equipment selector.

상기한 목적을 달성하기 위한 본 고안은 선택 액튜에이터와 주 액튜에이터 A, B를 작동시키기 위한 선택스풀과 메인스풀 A와 메인스풀 B가 설치되어 있는 메인콘트롤 밸브와 상기 메인 콘트롤 밸브에 파이로트 유압을 도입하여 주 액튜에이터 A, B (31) (32)를 작동시키기 위한 원격조작 밸브와, 상기 원격조작 밸브를 작동시키기 위한 원격조작 레버를 포함하는 중장비에 있어서, 상기 원격조작 레버의 상단에 설치된 전기식 스위치와 상기 전기식 스위치의 신호에 의하여 메인콘트롤 밸브의 선택스풀을 작동시키기 위해 솔레노이드 밸브 A와 솔레노이드 밸브 B로 구성된 파이로트 밸브를 포함하는 것을 특징으로 한다.In order to achieve the above object, the present invention introduces a pilot control to the main control valve and the main control valve in which the selection spool and the main spool A and the main spool B are installed to operate the selection actuator and the main actuators A and B. In the heavy equipment comprising a remote control valve for operating the main actuators A, B (31) (32), and a remote control lever for operating the remote control valve, the electric switch installed on the top of the remote control lever and It characterized in that it comprises a pilot valve consisting of a solenoid valve A and a solenoid valve B to operate the selection spool of the main control valve in response to the signal of the electrical switch.

이하 본 고안을 첨부도면에 의하여 상세히 설명한다.Hereinafter, the present invention will be described in detail by the accompanying drawings.

제1도는 본 고안의 유압회로도이고, 제2도는 본 고안의 작동상태를 도시하는 유압회로도로서, 선택 액튜에이터(33)작동용 선택스풀(36)과 주 액튜에이터 A(31) 작동용 메인스풀 A(34)와 주 액튜에이터 B(32)작동용 메인스풀 B(35)가 설치되어 있는 메인콘트롤 밸브(30)와 상기 메인콘트롤 밸브(30)에 파이로트 유압을 도입하여 주 액튜에이터 A, B(31)(32)를 작동시키기 위한 원격조작 밸브(10)와 상기 원격조작 밸브(10)를 작동시키기 위한 원격조작 밸브(10)를 포함하는 중장비에 있어서, 상기 원격조작 레버(11)의 상단에 설치된 전기식 스위치(12)와, 상기 전기식 스위치(12)의 신호에 의하여 메인콘트롤 밸브(30)의 선택스풀(36)을 작동시키기 위해 솔레노이드 밸브 A(21)와 솔레노이드 밸브 B(22)로 구성된 파이로트 밸브(20)를 포함하고 있다.FIG. 1 is a hydraulic circuit diagram of the present invention, and FIG. 2 is a hydraulic circuit diagram showing an operating state of the present invention, wherein the selection spool 36 for operating the selection actuator 33 and the main spool A for operating the main actuator A 31 are shown. 34) and the main actuators A and B (31) by introducing pilot hydraulic pressure into the main control valve 30 and the main control valve 30 in which the main spool B 35 for operating the main actuator B 32 is installed. A heavy equipment comprising a remote control valve (10) for operating the remote control valve (10) and a remote control valve (10) for operating the remote control valve (10). Pilot valve consisting of solenoid valve A 21 and solenoid valve B 22 for operating switch 12 and selection spool 36 of main control valve 30 in response to a signal of electrical switch 12. It contains 20.

제1도에 도시된 바와같이, 선택장치가 작동되지 않을경우에는 파이로트 밸브(20)에 설치되어 있는 솔레노이드 밸브 A, B(21)(22)의 위치가 불변산태로 있기 때문에 원격조작 밸브(10)로 부터의 파이로트 유압이 메인콘트롤 밸브(30)의 스풀챔버(X2, W2, X3, W3)에 전달되어 주 액튜에이터 A, B(31)(32)를 움직이게 한다.As shown in FIG. 1, when the selector is not operated, since the positions of the solenoid valves A and B (21) and 22 installed in the pilot valve 20 remain unchanged, the remote control valve ( The pilot hydraulic pressure from 10) is transmitted to the spool chambers X2, W2, X3, W3 of the main control valve 30 to move the main actuators A, B (31) 32.

또한, 제2도에 도시된 바와같이, 선택장치를 작동하는 경우에는, 원격조작 레버(11)의 상단에 설치되어 있는 전기식 스위치(12)의 신호에 의하여 파이로트 밸브(20)에 설치되어 있는 솔레노이드 밸브 A, B(21)(22)에 전기가 전달되어 솔레노이드 밸브 A, B(21)(22)의 위치가 변경되고, 원격조작 밸브(10)로 부터의 파이로트 유압이 메인콘트롤 밸브(30)의 선택스풀(36)의 파이로트 챔버(X1, W1)에 전달되어 선택 액튜에이터(33)를 움직이게 한다.In addition, as shown in FIG. 2, in the case of operating the selection device, the pilot valve 20 is provided by the signal of the electric switch 12 provided at the upper end of the remote control lever 11. Electricity is transmitted to solenoid valves A and B (21) and 22 so that the positions of solenoid valves A and B (21) and 22 are changed, and the pilot hydraulic pressure from the remote control valve 10 is controlled by the main control valve ( 30 is transmitted to pilot chambers X1 and W1 of selection spool 36 to move selection actuator 33.

이 경우, 원격조작 레버(11)와 전기식 스위치(12)를 복합적으로 조작하며, 선택 액튜에이터(33)와 주 액튜에이터 A, B(31)(32)를 동시에 작동되도록 할수도 있다.In this case, the remote control lever 11 and the electric switch 12 may be operated in combination, and the selection actuator 33 and the main actuators A, B 31 and 32 may be operated simultaneously.

상술한 바와같은 본 고안에 따르면, 전기식 스위치를 사용하게 되므로 운전실내의 공간을 적게 차지하게 되고, 운전자의 레버 조작성의 면에서도 편리하고, 복합작업시에도 향상되는 효과가 있다.According to the present invention as described above, since the use of the electric switch occupies less space in the cab, it is convenient in terms of the lever operability of the driver, there is an effect that is improved even during the compound work.
