본 고안은 상부체와 하부체가 상호 정방향 인지 역방향 인지를 감지하는 센서를 부착하여 정방향일 때는 주행선택레버가 후진 상태에 있을 때 후진 경고음을 발생시키고 역방향일 때는 주행선택레버가 전진 상태에 있을 때 후진경고음The present invention is equipped with a sensor for detecting whether the upper body and the lower body is forward or reverse mutually when the driving direction is in the reverse direction when the drive selection lever is in the reverse state, the reverse direction when the drive selection lever is in the forward state when the reverse Beep
을 발생시켜 결과적으로 운전자 관점에서의 후진시 후진 방향에 있는 사람들에게 경고음을 발생시켜 인적 안전사고를 예방하는 장치에 관한 것이다.The present invention relates to a device for preventing human safety accidents by generating a warning sound to people who are in the reverse direction when reversing from the driver's point of view.
종래의 휠타입 굴삭기의 후진 경고음 시스템은 상부체(6)의 선회상태에 상관없이 주행선택레버(2)가 후진상태에 있으면 무조건 후진 경고음을 발생시킨다.The backward warning sound system of a conventional wheel type excavator generates a reverse warning sound unconditionally when the driving select lever 2 is in the reverse state regardless of the turning state of the upper body 6.
(도 5 참조) 그래서 만약 상부체(6)가 180도 선회하여 하부체(7)와 역방향을 이룰 때는 운전자의 정면방향으로 주행을 하게 되는 데도 후진 경고음을 발생시키거나 운전자의 후면 방향으로 주행을 하게 되는 데도 후진 경고음을 발생시키지 않는 문제점이 있었다.Thus, if the upper body 6 is turned 180 degrees to the opposite direction to the lower body 7, the driver generates a backward warning sound or travels in the rear direction of the driver even when the upper body 6 is driven backward. There was a problem that does not generate a reverse warning sound.
특히 후자의 경우는 그 주행방향에 다른 사람이 있을 경우 운전자는 그 사람을 보지 못하고 그 사람도 경고음을 듣지 못하여 인적 안전사고가 발생하기 쉽다.(도4참조)In particular, in the latter case, when there is another person in the driving direction, the driver does not see the person and the person does not hear the warning sound, so human safety accidents are likely to occur (see Fig. 4).
본 고안은 이상과 같은 문제점을 해결하기 위한 것으로 상부체(6)와 하부체(7)가 정방향을 이루는지 역방향을 이루는지 여부를 반원형 보조판(12)과 근접센서(11)를 부착하여 감지하고 이를 주행선택레버(2)의 주행방향 선택 스위치(3)와 연계하여 후진경고음을 발생시킴으로써, 작업자가 굴삭기의 후진상태를 인지하지 못함으로 인해 발생될 수 있는 모든 안전사고등을 미연에 방지하고자 하는 것을 목적으로 한다.The present invention is to solve the above problems by detecting whether the upper body (6) and the lower body (7) in the forward or reverse direction by attaching a semi-circular auxiliary plate 12 and the proximity sensor 11 and By generating a backward warning sound in conjunction with the driving direction selection switch (3) of the drive selection lever (2), to prevent any safety accidents that may occur due to the operator does not recognize the backward state of the excavator For the purpose of
본 발명의 후진 경고음 발생 시스템은 선회 베어링 하우징 쪽에 부착된 선회방향 감지센서와 캐빈 내에 있는 전후진 선택 스위치 그리고 센서 신호와 선택 스위치를 이용하여 후진 경고음 발생여부를 결정하는 전기 회로 및 경고음을 발생시키는 부저로 이루어진 것을 특징으로 한다.The reverse warning sound generating system of the present invention is a buzzer for generating a warning sound and an electric circuit for determining whether the reverse warning sound is generated by using a direction sensor and a forward and backward selection switch in the cabin, and a sensor signal and a selection switch attached to the swing bearing housing.
