Description

덤프트럭의 덤핑 경고센서 {Dumping Warning Sensor For A Dump Truck}Dumping Warning Sensor For A Dump Truck}

본 발명은 덤프트럭의 적재부 덤핑시 덤핑경고를 발생시키기 위하여 트럭의 적재부와 데크에 설치하는 광학식 근접센서를 이용한 덤핑 경고센서에 관한 것이다.The present invention relates to a dumping warning sensor using an optical proximity sensor installed in the loading section and the deck of the truck to generate a dumping warning when dumping the loading section of the dump truck.

덤프트럭은 크게 탑승공간인 캡, 적재부, 적재부를 지지하며 바퀴가 부착되는 데크로 구성된다. 적재물을 쏟기 위하여 적재부가 데크로부터 이탈하여 기울어지는 것을 덤핑이라고 하는데, 트럭의 덤핑시에는 탑승자와 주변인원에 덤핑사실을 알리기 위하여 경고를 발생한다. 종래에는 덤핑여부를 알기 위하여 적재부 하단에 기계식 틸트록 센서를 장착하였고, 데크 상단에는 틸트록 센서에 상응하는 브라켓을 설치하였다. The dump truck is largely composed of a deck, which is equipped with wheels, supporting a cap, a loading part, and a loading part. The dumping of the load off the deck to dump the load is called dumping. When the truck is dumped, a warning is issued to inform the occupants and the surrounding personnel of the dumping fact. Conventionally, a mechanical tilt lock sensor is mounted at the bottom of the loading unit to know whether it is dumped, and a bracket corresponding to the tilt lock sensor is installed at the top of the deck.

이하 도 1과 2를 참고하여 구체적으로 살펴보면, 틸트록 센서(50)는 적재부(30)의 하단에 설치되고, 브라켓(12)은 데크(10)의 상단에 설치되어 트럭의 적재시에는 센서의 접점이 브라켓에 닿아 있어 경보가 발생하지 않지만, 덤핑시에는 접점이 이탈하여 덤핑경보가 발생하도록 온,오프식으로 센서가 작동하였다.1 and 2, the tilt lock sensor 50 is installed at the bottom of the loading part 30, and the bracket 12 is installed at the top of the deck 10 so that the sensor is loaded when the truck is loaded. The contact of is in contact with the bracket so that no alarm occurs. However, the sensor was operated on and off so that the dumping alarm occurred when the contact point was released.

도 2를 참고하여 틸트록 센서(50)를 살펴보면, 적재부(30)의 하단에 센서베 이스(54)가 설치되고, 구동부는 고무소재의 주름부츠(56)에 쌓여 보호되며 끝단에 접촉부(58)가 형성되어 있었다. 센서베이스(54)의 상단에는 접점의 이탈여부를 경보 발생부에 전달하기 위한 리드와이어(52)가 장착되어 있었다.Looking at the tilt lock sensor 50 with reference to Figure 2, the sensor base 54 is installed on the lower end of the loading portion 30, the driving portion is protected by piled up in the corrugated boots 56 of the rubber material and the contact portion (end) 58) was formed. At the upper end of the sensor base 54, a lead wire 52 for transmitting the detachment of the contact portion to the alarm generator is mounted.

그러나 종래의 틸트록 센서는 장착시 접촉부와 브라켓 사이의 장착거리 조절이 중요하나 단품제작인바 불량장착이 다수 발생하였으며, 적재시 주름부츠는 주름진 상태로 장시간 지속되어 부식과 파손이 발생하였고, 리드와이어와 센서베이스 사이의 틈새로 투수가 되어 내부 부품의 부식으로 내구성에 문제가 있었다.However, in the conventional tilt lock sensor, it is important to control the mounting distance between the contact part and the bracket, but many defects occurred due to the single product manufacturing.In the case of loading, the wrinkle boots were wrinkled and lasted for a long time to cause corrosion and breakage. There was a problem in durability due to the corrosion of internal parts due to the pitch between the sensor base and the sensor base.

본 발명은 이러한 문제점을 해결하기 위하여 제안된 것으로 광학식 근접센서를 이용하여 불량장착의 가능성을 줄이며, 투수구를 형성하여 부식을 방지고, 센서의 내구성을 증대시키는데 그 목적이 있다.The present invention has been proposed to solve the above problems, and the purpose of the optical proximity sensor is to reduce the possibility of bad mounting, to form a pitcher to prevent corrosion, and to increase the durability of the sensor.

상기의 목적을 달성하기 위한 본 발명에 따른 덤핑트럭의 덤핑 경고센서는 덤핑 감지부와 차단막으로 구성된다.The dumping warning sensor of the dumping truck according to the present invention for achieving the above object is composed of a dumping detector and a blocking film.

덤핑 감지부는 덤프트럭의 데크상단에 설치되며 일정한 내부공간이 형성된 센서베이스, 센서베이스의 내면에 부착되는 광원, 광원과 마주보도록 부착되며 광원의 빛을 탐지하여 전기적 신호를 방출하는 광검출기로 구성된다.The dumping detection unit is installed on the deck of the dump truck, and consists of a sensor base having a predetermined internal space, a light source attached to the inner surface of the sensor base, a light detector attached to face the light source, and detecting an light from the light source to emit an electrical signal. .

차단막은 덤프트럭의 적재상태에서는 상기 내부공간에 위치하여 광원의 빛을 차단하고, 덤핑시에는 광검출기에 빛이 전달될 수 있도록 덤프트럭의 적재부 하단 에 설치된다.The blocking film is located in the interior space of the dump truck to block the light of the light source, and when dumped is installed at the bottom of the loading portion of the dump truck so that light can be transmitted to the photodetector.

상기 광원과 광검출기는 각각 센서베이스의 내벽에 마련된 홀에 밀착삽입되어 투수가 방지되고, 광원은 발광다이오드로 함이 바람직하다. 센서베이스 내부공간의 하단부에는 중심이 통공된 원뿔형의 경사로가 형성되어 빗물 등이 유입될 경우 통공을 따라 투수가 이루어진다.Preferably, the light source and the photodetector are inserted in close contact with holes provided in the inner wall of the sensor base to prevent permeation, and the light source is preferably a light emitting diode. At the lower end of the sensor base internal space, a conical ramp with a central hole is formed, and when rainwater is introduced, a pitcher is formed along the hole.

상술한 바와 같은 구조로 이루어진 덤프트럭의 덤핑 경고센서에 따르면, 종래의 틸트록 센서와 달리 감지부가 비접촉식인바 불량조립과 오작동의 가능성이 줄어들며, 투수구가 형성되고 광원과 광검출기가 내벽에 들어가 있어 투수로 인한 부식을 방지할 수 있고 센서의 내구성이 증대된다.According to the dumping warning sensor of the dump truck structured as described above, unlike the conventional tilt track sensor, the detection unit is a non-contact type, reducing the possibility of defective assembly and malfunction, the pitcher is formed and the light source and the photodetector are in the inner wall Corrosion due to permeation can be prevented and the durability of the sensor is increased.

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시 예에 따른 덤프트럭의 덤핑 경고센서에 대하여 살펴본다.Hereinafter, a dumping warning sensor of a dump truck according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings.

도 3을 참고하여 살펴보면, 덤핑 경고센서는 덤핑 감지부와 차단막(500)으로 구성되며 덤핑 감지부는 센서베이스(300), 광원(360)과 광검출기(380)로 이루어진다. 센서베이스(300)는 트럭의 데크(100) 상단에 볼팅(120) 설치되며 일정 내부공간(320)이 형성되어 부품이 장착된다. 센서베이스(300)의 내부공간 내벽에는 부품설치를 위한 홀(340)이 형성되어 있고, 광원(360)과 광검출기(380)가 마주보도록 홀(340)에 밀착삽입된다. 광원(360)은 발광다이오드를 사용함이 바람직하고, 광검출기(380)는 광원(360)의 빛을 인식하여 전기적인 신호로 변환하게 된다.Referring to FIG. 3, the dumping warning sensor includes a dumping detector and a blocking film 500, and the dumping detector includes a sensor base 300, a light source 360, and a photodetector 380. Sensor base 300 is installed on the top of the deck (100) of the truck 120 and a predetermined internal space 320 is formed is mounted parts. A hole 340 is formed on the inner wall of the inner space of the sensor base 300, and is closely inserted into the hole 340 so that the light source 360 and the photodetector 380 face each other. Preferably, the light source 360 uses a light emitting diode, and the photodetector 380 recognizes the light of the light source 360 and converts the light into an electrical signal.

차단막(500)은 트럭의 적재부 하단에 설치되는데, 브라켓(520)으로 고정됨이 바람직하다. 상기 구성에 따를 때, 트럭의 적재시에는 적재부의 차단막(500)이 광원(360)의 빛을 가리고, 트럭의 덤핑시에는 차단막(500)이 적재부와 같이 상승되어 광원(360)의 빛을 광검출기(380)가 감지하여 경고 발생부에 전기적 신호를 방출한다. 차단막(500)은 덤핑 감지부와 비접촉식이므로 불량장착과 센서의 오작동을 방지할 수 있다.The blocking film 500 is installed at the bottom of the loading part of the truck, and is preferably fixed by the bracket 520. According to the above configuration, when the truck is loaded, the blocking film 500 of the loading unit covers the light of the light source 360, and when the truck is dumped, the blocking film 500 is raised together with the loading unit to emit the light of the light source 360. The photodetector 380 detects and emits an electrical signal to the warning generator. Since the blocking film 500 is non-contact with the dumping detection unit, it is possible to prevent defective mounting and malfunction of the sensor.

센서베이스 내부공간(320)의 하단부에는 중심이 통공된 원뿔형의 경사로(390)가 형성되어, 빗물 등의 투수시 경사로(390)를 따라 물이 모여 투수구를 통하여 배출됨으로써 내부 부품의 부식 등을 방지함이 바람직하다.At the lower end of the sensor base internal space 320, a conical ramp 390 having a central hole is formed, and water is collected along the ramp 390 when the rainwater is thrown out and discharged through the pitcher to prevent corrosion of internal components. Prevention is preferred.
