Is triggered by an alert to the user. In this case, the alarm unit 7 may be made of any one of a buzzer, a bell and a lamp, or a combination thereof.

컨트롤러(9)는 브레이크 압력 스위치(1), 램 록킹 스위치(3) 및 변속레버 중립 스위치(5)로부터 신호를 입력받아, 건설장비의 주차 솔레노이드(미도시)를 제어함과 동시에 건설장비의 주차 상태에서 변속레버(미도시)가 중립위치에서 전진 또는 후진하기 위한 주행위치로 변경될 경우, 주행작동을 차단시키고 알람부(7)를 통해 사용자에게 경고를 한다.The controller 9 receives signals from the brake pressure switch 1, the ram locking switch 3 and the shift lever neutral switch 5 to control the parking solenoid (not shown) of the construction equipment and simultaneously park the construction equipment. When the shift lever (not shown) is changed from the neutral position to the traveling position for moving forward or backward, the driving operation is blocked and the user is warned through the alarm unit 7.

미설명부호 2는 램 록킹 솔레노이드, 13은 배터리, 15는 주차스위치이다.Reference numeral 2 is a ram locking solenoid, 13 is a battery and 15 is a parking switch.

이와 같이 구성된 본 발명에 따른 휠타입 건설장비의 주행방지장치의 작동을 설명하면 다음과 같다.Referring to the operation of the driving prevention device of the wheel-type construction equipment according to the present invention configured as described above are as follows.

먼저, 건설장비에 탑승한 운전자가 건설장비에 시동을 걸어 건설장비를 주행시키는 경우, 운전자가 부주의로 인해 램 록킹장치를 해제하지 않거나 풋 브레이크를 밟지 않은 상태에서는 브레이크 압력 스위치(1) 또는 램 록킹 스위치(3)가 오프(OFF) 상태가 되고, 이 상태에서 변속레버의 중립위치가 변경되면 변속레버 중립 스위치(5)가 오프된다. 컨트롤러(9)는 상기 상태를 판단하여 건설장비의 주차불능 상태가 되도록 주차 솔레노이드(11)를 작동시키고, 아울러 알람부(7)를 통해 운전자에게 에러를 알린다.First, when a driver in construction equipment starts the construction equipment to drive the construction equipment, the brake pressure switch (1) or the ram locking does not occur when the driver inadvertently releases the ram locking device or presses the foot brake. The switch 3 is turned OFF, and in this state, the shift lever neutral switch 5 is turned off when the shift position neutral position is changed. The controller 9 determines the state and operates the parking solenoid 11 to be incapable of parking the construction equipment, and notifies the driver of the error through the alarm unit 7.

한편, 컨트롤러(9)는 브레이크 압력 스위치(1) 및 램 록킹 스위치(3)가 모두 오프(OFF)상태 즉, 운전자가 풋 브레이크를 밝고, 램 록킹을 해제한 상태에서 변속레버를 중립위치에서 주행위치로 이동하여 변속레버 중립 스위치(5)가 오프(OFF)되면 건설장비의 주차 솔레노이드(11)를 작동시켜 건설장비의 주행 가능상태가 되도록 제어한다.On the other hand, the controller 9 drives the shift lever in a neutral position with both the brake pressure switch 1 and the ram locking switch 3 OFF, ie, the foot brake is turned bright by the driver and the ram locking is released. When the shift lever neutral switch 5 is turned to OFF, the parking solenoid 11 of the construction equipment is operated to control the construction equipment to be capable of traveling.

상기와 같이 본 발명에 있어서는, 운전자가 부주의로 인해 램 록킹장치를 해제하지 않거나 풋 브레이크를 밟지 않은 상태에서 변속레버를 작동시킬 경우, 건설장비의 주행이 불가능하도록 조치함에 따라, 장비가 요동하거나 전복되는 것을 방지하여 장비의 파손 및 운전자의 안전사고를 미연에 예방할 수 있는 이점이 있다.As described above, in the present invention, when the driver operates the shift lever without inadvertently releasing the ram locking device or pressing the foot brake due to the driver's carelessness, the equipment may be moved or rolled over as the driving of the construction equipment is impossible. By preventing the damage to the equipment and the driver's safety accident has the advantage that can be prevented in advance.

이상에서는 본 발명을 특정의 바람직한 실시예를 예를 들어 도시하고 설명하였으나, 본 발명은 상기한 실시예에 한정되지 아니하며 본 발명의 정신을 벗어나지 않는 범위 내에서 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 다양한 변경과 수정이 가능할 것이다.In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments, and the present invention is not limited to the spirit of the present invention. Various changes and modifications will be possible by those who have the same.
