본 고안의 탑승교 승강장치도 제2도에서 도시된 바와같이, 휠캐리지(50) 상단에 하이드로유닛(41)이 고정되고, 하이드로유닛(41) 상부 양측에 각기 외측컬럼(42)과 내측컬럼(43)이 슬라이딩 가능하게 체결되며, 내측컬럼(43) 내부에 실린더(44)와 실린더로드(45)가 장치되고, 외측컬럼(42) 상단과 하단에 각기 마운팅브라켓(46)이 형성되어 마운팅브라켓(46)에 의해 턴넬(10)이 지지되는 것은 종래와 같다. 단, 본 고안은 제3도와 제4도에서 도시되는 바와같이, 내측컬럼(43) 외주면에 내부가 확대되는 요홈이 축방향으로 형성되어 요홈에 래크(47)가 견고하게 삽입되고, 래크(47)의 기어 전면쪽이 통공되게 외측컬럼(42)에 체결구멍(42a)이 형성되며, 외측컬럼(42)의 외주면에 탑승교의 높이 감지용 엔코더(49)가 취부되고, 체결구멍(42a)을 통해 래크(47)와 맞물리는 피니언기어(48)가 엔코더(49)에 커플링됨을 그 기술적 구성상의 기본 특징으로 한다.As shown in FIG. 2, the boarding bridge elevating device of the present invention has a hydro unit 41 fixed to the top of the wheel carriage 50, and an outer column 42 and an inner column respectively on both sides of the upper hydro unit 41. 43 is slidably fastened, the cylinder 44 and the cylinder rod 45 is installed inside the inner column 43, and mounting brackets 46 are formed at the upper and lower ends of the outer column 42, respectively, for mounting brackets. The turnnel 10 is supported by 46 is conventional. However, in the present invention, as shown in FIG. 3 and FIG. 4, the inner groove is formed on the outer circumferential surface of the inner column 43 in the axial direction so that the rack 47 is firmly inserted into the groove, and the rack 47 The fastening hole 42a is formed in the outer column 42 so that the front side of the gear is through, and the height detecting encoder 49 of the boarding bridge is attached to the outer circumferential surface of the outer column 42, and the fastening hole 42a is provided. The pinion gear 48 meshing with the rack 47 is coupled to the encoder 49 as a basic feature of the technical configuration.

이와 같이 구성되는 본 고안은 자중에 의해 턴넬(10)이 하강되고, 하이드로유니트(41)의 작동에 의해 실린더(44)가 외측컬럼(42)과 함께 턴넬(10)을 상승시키게 되며, 외측컬럼(42)의 상승 및 하강시 피니언기어(48)가 내측컬럼(43)에 고정된 래크(47)에 의해 회전된다. 또한, 회전되는 피니언기어(48)가 엔코더(49)에 기계적인 신호를 입력시키고, 엔코더(49)가 기계적인 신호를 전기적인 펄스신호로 변환시켜 출력하게 된다.The present invention constituted as described above, the turnnel 10 is lowered by its own weight, the cylinder 44 by the operation of the hydro unit 41 to raise the turnnel 10 together with the outer column 42, the outer column When the 42 is raised and lowered, the pinion gear 48 is rotated by the rack 47 fixed to the inner column 43. In addition, the pinion gear 48 to be rotated inputs a mechanical signal to the encoder 49, and the encoder 49 converts the mechanical signal into an electrical pulse signal and outputs the mechanical signal.

연기에서, 엔코더(49)는 1회전당 1000펄스의 로터리식이 적용되며, 피니언기어(48)에 연동되게 연결되고, 엔코더(49)의 출력측에 카운터(49a)가 연결되며, 카운터(49a)에 리세트용 리미트스위치(49b)가 장치된다.In the acting, the encoder 49 is applied with a rotary pulse of 1000 pulses per revolution, connected to the pinion gear 48 interlocked, the counter 49a is connected to the output side of the encoder 49, and connected to the counter 49a. A reset limit switch 49b is provided.

이러한 엔코더(49)는 피니언기어(48)의 회전에 따른 이동거리가 로터리를 통해 회전에 따른 펄스(pulse) 시그널이 전기적인 신호로 변환되어 출력되며, 전기적인 펄스시그널이 카운터(49a)에 입력되면, 펄스신호가 프리스케일(free scale) 기능을 가진 카운터(49a)가 이를 감지하여 모니터에 나타나게 된다. 또한, 높이를 감지하는 엔코더(49)의 위치가 일정높이에 이르면, 리미트스위치(49b)가 작동되어 입력된 일정높이의 치수가 카운터(49a)에 리세트된다.In the encoder 49, the movement distance according to the rotation of the pinion gear 48 is converted into an electrical signal by a pulse signal according to the rotation through a rotary, and the electrical pulse signal is input to the counter 49a. When the pulse signal is detected, the counter 49a having a free scale function detects it and appears on the monitor. In addition, when the position of the encoder 49 for detecting the height reaches a certain height, the limit switch 49b is operated to reset the input dimension of the predetermined height to the counter 49a.

한편, 카운터(49a)의 모니터에 디스플레이 되는 높이는, 피니언기어(48)의 지름에 따른 1회전당 이동거리와 로터리 1회전당의 펄스수에 의해, 1펄스단위로 카운터(49a)에 입력되어 나타난다.On the other hand, the height displayed on the monitor of the counter 49a is inputted to the counter 49a in units of one pulse by the movement distance per revolution according to the diameter of the pinion gear 48 and the number of pulses per rotary revolution. .

따라서, 이러한 본 고안은 높이 감지장치가 래크(47)와 피니언기어(48)에 의해 엔코더(49)가 구동되도록 하므로, 그 취부상태가 견고하여 고장요인이 없으며, 엔코더(49)의 펄스신호를 출력하여 카운터(49a)에 프리스케일 기능으로 나타내므로, 탑승교의 운전자가 보다 신속하고 정확하게 비행기와 접현할 수 있으며, 비행기 동체와 탑승교의 위치를 정확하게 맞춤으로써 기체손상을 방지할 수 있다. 또한, 일정높이를 통과할 때 리세트되는 기능이 부가되어, 원주에서 발생되는 누적오차를 제거해 준다.Therefore, the present invention allows the encoder 49 to be driven by the rack 47 and the pinion gear 48, so that the mounting state is firm, there is no failure factor, and the pulse signal of the encoder 49 is transmitted. Since the output is displayed on the counter 49a as a freescale function, the driver of the boarding bridge can make contact with the plane more quickly and accurately, and the aircraft body can be prevented by precisely aligning the position of the plane and the boarding bridge. It also adds the ability to reset when passing a certain height, eliminating cumulative errors that occur on the circumference.

이상에서 살펴본 바와 같이, 본 고안은 래크와 피니언 기어를 컬럼에 조합시키고, 피니언기어에 의해 로터리 엔코더가 구동되어, 엔코더에서 출력된 펄스신호가 모니터에 프리스케일로 나타내므로, 고장이 없이 신속하고 정밀한 감지를 얻을 수 있는 매우 유용한 것이다.As described above, the present invention combines the rack and pinion gear in a column, and the rotary encoder is driven by the pinion gear, so that the pulse signal output from the encoder is displayed on the monitor as freescale, so that it is quick and precise without trouble. It is very useful to get the detection.
