본 고안은 휠로우더와 같은 건설 중장비의 야간 작업시, 작업의 안전성 확보 및 작업효율을 위해 작업등이 작업장치(Bucket)의 위치나 방향에 따라 자동적으로 각도가 제어되게 되는 건설중장비의 작업등 방향제어 장치에 관한 것이다.The present invention is to control the direction of the work light of heavy construction equipment such that the work light is automatically controlled according to the position or direction of the work bucket for securing safety and working efficiency during night work of heavy construction equipment such as wheel loaders. Relates to a device.

종래의 건설중장비에서는 작업등이 일정방향으로만 조사되도록 고정된 구조이므로 야간에 직선방향으로만 왕복 주행하면서 작업하는 경우에는 불편함이 없지만, 지속적으로 전후진하고 좌,우회전하면서 작업을 해야 하는 휠로더 또는 지게차 등의 건설중장비에 의한 작업시에는 작업등이 주행방향과는 관계없이 전방만 조사하게 되므로, 좌 또는 우로 선회주행하면서 이루어지는 작업시에는 작업등이 작업할 부위를 제대로 비취지 못하게 됨에 의해, 전방 돌출물과 충돌하게 되는 등의 안전사고를 당할 수 있는 문제점이 있었다.In the conventional heavy construction equipment, the work light is fixed so as to be irradiated only in a certain direction, so there is no inconvenience when working while traveling only in a straight direction at night, but wheel loaders or forklifts that have to work continuously while moving forward and backward and turning left and right When working with heavy construction equipment such as the light, the work light is irradiated only forward regardless of the driving direction, so when the work is made while turning left or right, the work light may not be able to properly illuminate the part to be worked, thereby colliding with the front protrusion. There was a problem that can be a safety accident.

본 고안은 이상과 같은 문제점을 해결하기 위해 안출된 것으로, 핸들의 조향각도에 따라 작업등이 자동적으로 각도제어되도록 하여 작업등은 건설중장비의 주행방향과 관계없이 항상 작업할 부위를 조사하도록 함에 의해 전방돌출물과 충돌하는 등의 안전사고를 예방케하고 작업을 용이토록 하는데에 목적이 있는 것이며, 그 해결방안으로 핸들 조향각도를 감지하는 조향각 센서를 구비하고 상기 센서에서 조향각이 좌 또는 우로 일정각도 이상 선회된 것으로 감지되면 솔레노이드 밸브를 작동하도록 하여 상기 솔레노이드 밸브의 스풀 연결부에 연결된 작업등이 각도제어되도록 함에 의해 작업등이 항상 작업할 부위를 비취도록 하고 있다.The present invention was devised to solve the above problems, the work light is automatically angled in accordance with the steering angle of the handle so that the work light is always projected by irradiating the site to work regardless of the driving direction of the heavy construction equipment It aims to prevent safety accidents such as colliding with the vehicle and to facilitate the work. The solution includes a steering angle sensor that detects the steering wheel steering angle, and the steering angle is turned over a certain angle to the left or right. If it is detected that the solenoid valve is operated so that the work light connected to the spool connection portion of the solenoid valve is angle-controlled so that the work light is always shining the work area.

첨부도면에 의해 본 고안의 구성을 좀 더 상세히 설명하면 다음과 같다.Referring to the configuration of the present invention in more detail by the accompanying drawings as follows.

제1도는 본 고안의 시스템 설명도이며, 제2도는 본 고안의 제어흐름도로서 먼저 제1도에서 보면, 핸들(13)의 축상에 설치된 조향각센서(1)와, 상기 조향각센서(1)로부터의 전기신호가 입력되도록 조향각센서(1)와 연결된 제어기(2)와, 상기 제어기(2)로부터의 전기신호가 출력되도록 제어기(2)와 각각 연결되며, 그 스풀연결부(9,10,11,12)들은 각각 2개씩 좌,우측작업등(7,8)의 좌우측에 각각 연결되는 솔레노이드 밸브(3,4,5,6)로 구성된다.1 is a system explanatory diagram of the present invention, and FIG. 2 is a control flow diagram of the present invention. First, as shown in FIG. 1, a steering angle sensor 1 installed on an axis of a handle 13 and the steering angle sensor 1 The controller 2 is connected to the steering angle sensor 1 so that the electric signal is input, and the controller 2 is connected to the controller 2 so that the electric signal from the controller 2 is output. The spool connection parts 9, 10, 11, 12 are respectively connected. Are each composed of solenoid valves 3, 4, 5 and 6 connected to the left and right sides of the left and right working lights 7 and 8, respectively.

즉, 솔레노이드 밸브(3,4)의 스풀과 각각 연결된 스풀연결부(9,10)는 좌측작업등(7)의 배면 좌,우측에 각각 연결되고, 솔레노이드 밸브(5,6)의 스풀과 각각 연결된 스풀연결부(11,12)는 우측작업등(8)의 배면 좌,우측에 각각 연결된다.That is, the spool connecting portions 9 and 10 respectively connected to the spools of the solenoid valves 3 and 4 are connected to the left and right sides of the rear work lamp 7, respectively, and are connected to the spools of the solenoid valves 5 and 6, respectively. The spool connecting portions 11 and 12 are connected to the rear left and right sides of the right work lamp 8, respectively.

또한, 제2도에 도시된 바와 같이 상기 제어기(2)는 조향각센서(1)로부터의 입력신호가 -15°이하가 되면 솔레노이드 밸브(3,5)가 ON되도록 전기신호를 출력토록 하고, 조향각센서(1)로부터의 입력신호가 15°이상이 되면 솔레노이드밸브(4,6)가 ON되도록 전기신호를 출력하며, 조향각센서(1)로부터의 입력신호가 -15°초과에서 15°미만일 경우에는 모든 솔레노이드밸브(3,4,5,6)를 OFF하도록 구성된다.In addition, as shown in FIG. 2, the controller 2 outputs an electric signal so that the solenoid valves 3 and 5 are turned on when the input signal from the steering angle sensor 1 becomes -15 ° or less. When the input signal from the sensor 1 is 15 ° or more, the electric signal is output so that the solenoid valves 4 and 6 are turned on. When the input signal from the steering angle sensor 1 is less than 15 ° from -15 °, It is configured to turn off all solenoid valves (3, 4, 5, 6).

이상과 같이 구성되는 본 고안 장치는 다음과 같이 작동한다.The device of the present invention configured as described above operates as follows.

휠로더와 같은 건설중장비에 의해 야간작업시 작업자가 좌측에 위치한 작업위치로 가기 위해 핸들(13)을 좌측으로 15°이상 돌리게 되면 조향각 센서(1)에서 감지되어, 제어기(2)에서 제2도에 도시된 바와 같이 솔레노이드 밸브(3,5)를 ON시키게 된다. 이에 따라 상기 솔레노이드밸브(3,5)의 스풀과 함께 타단이 좌,우측 작업등(7,8)의 우측에 연결된 스풀연결부(9,11)가 신장하게 된다.If the operator turns the handle 13 more than 15 ° to the left side to go to the work position on the left side during heavy work such as a wheel loader, it is detected by the steering angle sensor 1, and the controller 2 As shown, the solenoid valves 3 and 5 are turned on. Accordingly, the spool connecting portions 9 and 11 connected to the right side of the left and right working lights 7 and 8 together with the spools of the solenoid valves 3 and 5 extend.

따라서 좌,우측 작업등(7,8)은 반시계 방향으로 일정각도만큼 선회하게 되며, 좌측에 위치한 작업위치를 비취게 되는 것이다.Accordingly, the left and right work lights 7 and 8 are rotated by a predetermined angle in the counterclockwise direction, and the work position on the left side is reflected.

또한, 작업자가 핸들(13)을 우측으로 15°이상 돌리게 되면 상기한 방법과 같이 솔레노이드 밸브(4,6)가 ON되며, 이에 따라 스풀연결부(10,12)가 신장하게 되므로, 좌,우측 작업등(7,8)은 시계방향으로 일정각도 만큼 선회하게 되며, 우측에 위치한 작업위치를 비취게 되는 것이다.In addition, when the operator turns the handle 13 to the right by 15 degrees or more, the solenoid valves 4 and 6 are turned on as described above, and thus the spool connecting portions 10 and 12 are extended, so that the left and right operations are performed. The back (7,8) is to be rotated clockwise by a certain angle, to reflect the working position located on the right.

또한, 핸들(13)이 15°이내에서 선회하게 되면 모든 솔레노이드 밸브(3,4,5,6)가 OFF되므로, 스풀연결부(9,10,11,12)들은 모두 원위치로 복귀되어 좌,우측 작업등(7,8)은 정면을 향하게 되는 것이다.In addition, when the handle 13 is turned within 15 °, all the solenoid valves 3, 4, 5, and 6 are turned off, so that the spool connecting parts 9, 10, 11, and 12 are all returned to their original positions and left and right sides are The work lights 7 and 8 are directed to the front.

이와 같이 본 고안은 핸들 조향각도를 감지하는 조향각 센서(1)를 구비하고 상기 센서에서 조향각이 좌 또는 우로 일정각도 이상 선회된 것으로 감지되면 솔레노이드 밸브(3,4,5,6)를 작동하도록 하여, 상기 솔레노이드 밸브의 스풀연결부(9,10,11,12)에 연결된 작업등이 각도 제어되도록 함에 의해서, 작업등(7,8)이 항상 작업할 부위를 비취도록 하고 전방 돌출물과 충돌하는 등의 안전사고를 방지하게 되는 유용한 고안이다.As such, the present invention includes a steering angle sensor 1 for detecting a steering angle of the steering wheel, and when the steering angle is detected to be rotated by a predetermined angle to the left or right, the solenoid valves 3, 4, 5, and 6 are operated. By the angle control of the work light connected to the spool connection portion 9, 10, 11, 12 of the solenoid valve, the work light (7, 8) is always illuminated to the work area and collides with the front projection It is a useful design to prevent accidents.
