Description

비접촉 변위측정장치{APPARATUS FOR NONCONTACTALLY DISPLACEMENT MEASURING }Non-contact displacement measuring device {APPARATUS FOR NONCONTACTALLY DISPLACEMENT MEASURING}

본 발명은 기계장치의 변위를 측정하는 장치에 관한 것으로, 특히 중속, 저속엔진과 같은 대형 디젤엔진에서의 크랭크샤프트의 디프렉션(deflection)을 측정하기 위한 장치에 관한 것이다.
TECHNICAL FIELD The present invention relates to a device for measuring displacement of a mechanical device, and more particularly, to a device for measuring deflection of a crankshaft in a large diesel engine such as a medium speed and a low speed engine.

일반적으로 선박용 대형 디젤엔진의 경우 동력전달장치는 크게 실린더, 피스톤, 크랭크샤프트 등으로 구성이 되어있다. In general, in the case of large diesel engines for ships, the power transmission device is largely composed of a cylinder, a piston, a crankshaft, and the like.

이들 부품 중에서 크랭크샤프트는 엔진실린더의 폭발력을 전달받아 이를 회전력으로 전환하여 선박의 프로펠러나 발전기 등으로 동력을 전달하는 중요한 역할을 하므로 동력전달 중의 부하를 견딜 수 있도록 강한 구조로 설계된다. Among these parts, the crankshaft is designed to be strong to withstand the load during power transmission because it plays an important role in transmitting the power to the propeller or generator of the ship by receiving the explosion force of the engine cylinder and converting it to rotational force.

따라서 크랭크샤프트의 기계적 변형은 엔진의 조립과정 또는 엔진 운전 중의 어떠한 경우라도 변형이 되어서는 안 되므로 중요한 점검사항에 속하는 것이다.Therefore, the mechanical deformation of the crankshaft is an important check because it must not be deformed in any case during engine assembly or engine operation.

통상적으로 상기와 같은 점검사항을 확인하는 방법이 크랭크스로우(crankthrow)의 자체 축방향 변형량(deflection;이하 ‘디프렉션’이라 칭함)을 측정하는 것이며, 이러한 점검은 정기점검 혹은 수시로 엔진을 정지하여 디프렉션값을 확인한다.Normally, a method of confirming the above checks is to measure the crankthrow's own deflection (hereinafter, referred to as 'deflection'), and such checks are carried out at regular inspections or from time to time by stopping the engine. Check the selection value.

상기와 같이 디프렉션값을 측정하는 방법들로는 사람이 직접 수동 다이얼게이지를 사용하여 디스렉션값을 측정하는 방법 혹은 리니어 인코더 모듈을 사용하는 방법 등이 실시되어 왔다.As a method of measuring a deflection value as described above, a method of directly measuring a direction value using a manual dial gauge or a method using a linear encoder module has been performed.

하지만 이러한 통상적인 측정방법들은 측정자의 숙련도나 상황에 따른 측정기의 미세한 움직임에도 오차가 발생하고, 측정 중에 측정장치가 추락하는 등의 사례가 발생하여 고가의 측정장치를 파손하는 경우가 발생하기도 하였다.However, these conventional measuring methods cause errors even in the minute movements of the measuring device according to the skill or situation of the measuring person, and the measuring device falls during the measurement, thereby causing an expensive measuring device to be damaged.

이러한 불편함을 개선하는 디프렉션 측정장치의 일예로는 국내 등록특허 제956263호 “대형 디젤엔진용 비접촉식 디프렉션 측정장치”가 있다.An example of a deflection measurement apparatus for improving such inconvenience is a Korean Patent No. 956263, "Non-contact deflection measurement apparatus for large diesel engines."

국내 등록특허 제956263호에 개시된 종래기술은 디프렉션값을 측정함에 있어 비접촉식 센서를 구비한 센서본체와 센서보조체를 각각의 강자석에 의한 자력으로 크랭크샤프트의 크랭크스로우의 양측 내벽면에 부착 설치하는 방법을 사용하고 있다.In the prior art disclosed in Korean Patent No. 956263, a sensor body and a sensor auxiliary body having a non-contact sensor are attached to both inner wall surfaces of a crankshaft of a crankshaft by magnetic force by respective magnetic magnets in order to measure deflection values. I'm using the method.

이와 같은 비접촉 변위측정장치는 센서 본체에서 보내는 신호가 센서 보조체에 의하여 반사되고, 센서 보조체에 의하여 반사되는 신호의 정상 여부를 제어부에서 감지하여 크랭크샤프트의 변위를 측정하며, 측정된 신호는 무선으로 송신된다.Such a non-contact displacement measuring device is a signal from the sensor body is reflected by the sensor auxiliary body, the control unit detects the normality of the signal reflected by the sensor auxiliary to measure the displacement of the crankshaft, the measured signal is a wireless Is sent.

그러나 특허 제956263호의 비접촉 변위측정장치는 센서본체가 비접촉식 변위측정센서와 각도센서와 전자회로부와 배터리를 일체로 형성한 하우징 내부에 내장한 구성이고, 센서보조체는 일측단부에 감지편이 형성된 지지봉을 받침용브라켓에 결합한 구성으로서 하우징내에 전자회로가 장착된 기판이 불량이거나 고장 시에 쉽게 교체 또는 수리를 할 수 없을 뿐만 아니라 전자회로가 장착된 기판에 전원을 공급하는 배터리 또한 교체를 어렵게 하는 것이었고, 센서보조체는 길이 조정을 할 수 없어 크랭크스로우의 양측내벽면 사이의 간격에 따라 조정 사용할 수 없는 등의 문제점이 있는 것이었다.
However, the non-contact displacement measuring device of Patent No. 956263 has a structure in which the sensor body is built in a housing in which the non-contact displacement measuring sensor, the angle sensor, the electronic circuit part and the battery are integrally formed, and the sensor auxiliary body has a supporting rod having a sensing piece formed at one end thereof. In combination with the supporting bracket, the board with electronic circuit in the housing is not easy to replace or repair when the board is defective or broken, and also the battery that supplies power to the board with electronic circuit is difficult to replace. However, the sensor auxiliary body was not able to adjust the length, and there was a problem that it could not be used according to the gap between the inner wall surfaces of both sides of the crank throw.

본 발명의 목적은 대형 디젤엔진의 디프렉션값을 측정하는 비접촉 변위측정장치에 있어 크랭크샤프트내 크랭크스로우의 디프렉션값을 측정자가 보다 신속하고 편리하게 측정할 수 있으면서 비접촉 변위측정장치에서 회로기판 등의 고장이나 배터리 교체의 필요성이 있을 때 보다 신속하게 수리 또는 교체할 수 있고, 크랭크스로우의 벽면 간격에 따라 길이를 조정 사용할 수 있는 장치를 제공하는데있다.
