Description

케이블체인 및 대차를 이용한 알티지씨의 저압전원공급시스템{Low voltage supply system of Rubber Tyred Gantry Crane used cable chain and carriage}Low voltage supply system of Rubber Tyred Gantry Crane used cable chain and carriage}

본 발명은 에너지공급시스템을 케이블체인방식으로 하는 케이블체인 및 대차를 이용한 알티지씨(RTGC)의 저압전원공급시스템에 관한 것이다.The present invention relates to a low-voltage power supply system of RTGC (CRT) using a cable chain and a trolley using an energy supply system as a cable chain method.

종래의 RTGC는 경유를 사용한 발전기방식인 바 이는 유가상승에 따른 비용부담이 가증되는 등의 단점이 있으므로 이를 개선하여 고압케이블 릴을 이용한 육상전력공급시스템이 공지되어 있으나, 이는 초기투자비가 많이 소요되고, 상기 RTGC장비에 인가되는 중량이 6톤 정도로 무거울 뿐만 아니라 6600V의 주전원을 공용으로 사용하므로 한쪽 RTGC에 전기적 고장이 발생 시 고압 계전기 등의 예민한 차단동작으로 주전원이 차단되어 전체 RTGC가 가동되지 못하는 등의 문제점이 있으므로 본 발명은 상기의 문제점을 해결하고자 케이블체인방식에 의한 육상전력공급시스템을 안출한 것이다.Conventional RTGC is a generator method using diesel, which has disadvantages such as an increase in the cost burden due to the increase in oil prices. Therefore, a land power supply system using a high-voltage cable reel is known to improve this, but this requires a lot of initial investment cost. In addition, the weight applied to the RTGC equipment is about 6 tons, and since the main power of 6600V is shared, the main power is cut off due to sensitive cut-off operation such as a high-voltage relay, so that the entire RTGC cannot be operated. In order to solve the above problems, the present invention devised a land power supply system using a cable chain method.

본 발명은 케이블체인과 대차를 이용한 RTGC의 저압 전원공급시스템에 관한 것으로서, 이를 보다 상세히 설명하면 컨테이너하역장비인 RTGC(Rubber Tyred Gantry Crane)의 에너지공급시스템을 케이블체인방식으로 함으로서 경비를 절감하고 생산성을 증대할 수 있게 한 것이다.The present invention relates to a low-voltage power supply system of the RTGC using a cable chain and bogie, more specifically, to reduce the cost and productivity by using the energy supply system of the container loading equipment RTGC (Rubber Tyred Gantry Crane) It is to increase the.

종래에 항만이나 야적장에 설치된 컨테이너 하역장비인 RTGC의 에너지공급시스템은 유류를 사용한 발전기방식으로 가동하였으나 이는 대기환경오염과 엔진발전기의 잦은 정비에 따른 운영비 증가뿐만 아니라 급격한 유가상승으로 비용부담이 가중되는 단점이 있는바, 이를 개선하여 에너지 공금시스템을 유류에서 고압케이블 릴을 이용한 육상전력 공급시스템으로 전환하였으나 상기 고압케이블 릴 타입은 6,600V의 주전원을 사용하므로 한곳의 RTGC에 전기적 고장이 발생시에 고압 계전기의 특성상 주전원이 차단되어 전체 RTGC를 가동하지 못할 뿐만 아니라 설치된 RTGC마다 사용전압으로 변환하는 6600V/460V의 트랜스포머가 설치되므로 케이블 릴과 더불어 중량이 무겁고 특히 케이블 릴은 외국제품을 수입하여 사용함에 따라 초기 투자비가 많이 소요되는 등의 문제점이 있었다.Conventionally, the energy supply system of RTGC, which is a container unloading equipment installed in a port or a yard, is operated by a generator method using oil, which increases the operating cost due to air pollution and frequent maintenance of the engine generator, as well as a sudden increase in oil price. As a result, the energy supply system was changed from oil to a land power supply system using a high voltage cable reel. However, since the high voltage cable reel type uses a main power of 6,600 V, a high voltage relay is generated when an electrical failure occurs in one RTGC. Due to the nature of the main power, the entire RTGC is not operated and 6600V / 460V transformers are installed to convert the used voltage to each installed RTGC. Therefore, the weight of the cable reel is heavy. It costs a lot of investment There are problems such as.

본 발명은 상기의 문제점을 해결하고자 창안한 것으로서 이의 고안요지는 케이블체인과 체인가이드 및 대차 등으로 구성되는 RTGC의 저압전원 공급시스템은 공급전원이 필요전압인 460V의 저압전원을 사용하고 상기 RTGC의 이동시 사행운전(deviation)에 의해 전원 연결부가 수평방향으로 내·외측 각 80Cm의 오차범위와 타이어 진동에 의해 수직방향으로 상하 각각 30Cm의 오차범위로 이탈함을 대차와 연결로드(rod)를 이용하여 흡수할 수 있으며, 또한 상기 연결로드의 타단부와 고정 축이 체결되는 부분의 상단부에는 각도 검출센서(pulse encoder)를 장착하여 이탈정보를 실시간으로 장비제어부에 제공할 뿐만 아니라 저압을 사용함에 따라 한쪽 RTGC가 전기적으로 고장이 나더라도 다른 RTGC의 가동에 아무런 영향을 주지 않는 등의 특징이 있는 것이다.The present invention has been made to solve the above problems, and the subject matter of the present invention is a low voltage power supply system of RTGC consisting of a cable chain, chain guide and bogie, using a low voltage power supply of 460V supply voltage is required voltage of the RTGC When moving, the power connection part is separated by an error range of 80 cm inside and outside in the horizontal direction and 30 cm vertically in the vertical direction by tire vibration. The upper end of the other end of the connecting rod and the fixed shaft can be absorbed and equipped with a pulse encoder to provide deviation information in real time to the equipment control unit as well as to use one of the lower pressures. Electrical failure of the RTGC does not affect the operation of other RTGCs.

상기한 바와 같이 본 발명은 케이블체인과 대차를 이용한 RTGC의 저압전원공급시스템에 관한 것으로서, 이는 종래의 유류를 사용한 발전기방식의 가동방법에 비하여 에너지비용을 약85~90%가 절감할 수 있으며 또한 케이블 릴(cable reel)방식에 비해서도 구조가 간단하고 전력 배전반의 공급전압이460V의 분기식 저압을 사용함에 따라 한쪽 RTGC에 전기적 고장이 발생하여도 다른 RTGC의 가동에는 영향을 주지 않으며, 레인변경 시 저압단말 배선의 제거가 용이하고 공급시스템의 파손에 의한 고장시에는 연결로드와 배선을 제거하면 기존 엔진발전기를 즉시 운행이 가능하고 케이블 릴 방식에 비해 RTGC에 인가되는 중량은 대차를 끌 수 있는 500kg정도의 고정브라켓으로 해결되며 특히 케이블 릴 방식에 비해 구조가 간단하고 공사기간을 단축할 수 있어 설치비를 절감할 수 있을 뿐만 아니라 상기 RTGC의 이동시 사행운전(deviation)에 의한 전원장치의 충돌사고에 따른 손상을 방지할 수 있어 매우 경제적이고 실용적인 효과가 있는 것이다.As described above, the present invention relates to a low-voltage power supply system of RTGC using a cable chain and a bogie, which can reduce energy costs by about 85 to 90% compared to a conventional method of operating a generator using oil. Compared to the cable reel method, the structure is simpler and the supply voltage of the power switchboard uses 460V branched low voltage. Therefore, if one RTGC has an electrical failure, it does not affect the operation of the other RTGC. Low voltage terminal wiring is easy to remove, and in case of failure due to breakage of supply system, the existing engine generator can be operated immediately by removing the connecting rod and wiring, and the weight applied to RTGC can be pulled out compared to the cable reel method. It is solved with a fixed bracket of accuracy, and in particular, the structure is simpler than the cable reel method, and the construction period can be shortened. Not only can it reduce, but also the damage caused by the crash of the power supply device due to the deviation (deviation) during the movement of the RTGC is very economical and practical effect.

이를 도면에 의거하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the drawings as follows.

본 발명은 항만이나 야적장에서 컨테이너를 하역하는 장비인 RTGC의 저압전 원공급시스템에 관한 것이다.The present invention relates to a low-voltage power supply system of RTGC which is equipment for unloading containers at a port or a yard.
