Description

엘리베이터의 피트점검용 오토라이트{Auto light for pit inspection of an elevator}Auto light for pit inspection of an elevator

본 발명은 엘리베이터의 피트점검용 오토라이트에 관한 것으로, 보다 상세하게는 간단한 구조에 의해 승강장 도어의 개폐상태를 감지하여 자동적으로 조명을 비출 수 있도록 된 엘리베이터의 피트점검용 오토라이트에 관한 것이다. The present invention relates to an auto light for checking a pit of an elevator, and more particularly, to an auto light for checking a pit of an elevator that can automatically illuminate by detecting the open/closed state of a platform door by a simple structure.

일반적으로 엘리베이터의 점검이나 유지보수 작업과정에는 필요에 따라 승강카가 이동되는 승강로(피트) 상에 작업자가 진입할 경우가 발생되는데, 피트 내에 조명장치가 설치되지 않은 경우에 작업자가 직접적으로 손전등을 휴대하거나 피트 내에 조명장치가 설치된 경우에도 작업자가 직접적으로 조명장치를 온오프하도록 설치된 것이 대부분이다.In general, in the process of inspection or maintenance of an elevator, there is a case where an operator enters the hoistway (pit) where the elevator car is moved as needed. Or, even when a lighting device is installed in a pit, most of them are installed so that the operator can directly turn the lighting device on and off.

이러한 조명장치가 설치되는 않은 피트 내의 작업과정 중이거나 피트 내의 조명장치를 켜기 이전에 조명이 미비한 상태에서는 다양한 형태의 안전사고가 야기될 수 있는데, 예를 들면 작업자가 손전등 등을 한 손에 들고 피트 내에 진입하는 과정에서 사다리를 내려갈 때에 다른 손으로 사다리를 그립하거나 내려가는 자세 등이 부자연스러울 때나 조명장치를 켜기 위해 작업자가 피트 밖에서 한손으로 지탱한 상태로 몸을 숙여 다른 손으로 장치를 조작하는 작업과정에서 발생되는 것이다.Various types of safety accidents may occur during work in the pit where such a lighting device is not installed, or if the lighting is insufficient before turning on the lighting device in the pit, for example, a worker holding a flashlight in one hand When going down the ladder in the process of entering the building, when it is unnatural to grip the ladder with the other hand or when the downward posture is unnatural, or to turn on the lighting device, the operator bends down while supporting the device with one hand outside the pit and operates the device with the other hand will occur in

이와 같이 피트 내에 조명이 미비한 경우에는 조명장치를 켜기 위해 작업자의 자세가 불안정하거나 작업자가 피트 내로 진입하는 과정에서 시야를 확보하지 못하여 사다리의 설치상태 불량이나 피트 바닥의 오일 또는 마감상태 불량 등으로 인해 추락이나 전도 등과 같은 안전사고가 발생될 수 있는 것이다.In the case of insufficient lighting in the pit as described above, the operator's posture to turn on the lighting device is unstable, or the operator cannot secure a view while entering the pit. Accidents such as falls or falls may occur.

상술한 본 발명의 목적, 특징들 및 장점은 다음의 상세한 설명을 통하여 보다 분명해질 것이다. 이하, 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.The objects, features and advantages of the present invention described above will become more apparent through the following detailed description. Hereinafter, a preferred embodiment of the present invention will be described based on the accompanying drawings.

도 1과 도 2는 본 발명의 바람직한 일실시예를 도시한 것이다. 도 1에 도시된 바와 같이, 본 발명의 오토라이트(30)는 일정 크기의 박스형태로 된 조명박스(31)가 구비되고, 이 조명박스(31)의 전면에 투명재질의 판형태로 된 투광패널(32)이 개폐 가능하게 결합된 것으로, 상기 조명박스(31) 내에는 투광패널(32)을 통해 빛을 조사하도록 된 LED조명패널(33a)과 안정기(33b) 등을 포함한 조명모듈(33)이 설치되고, 상기 조명모듈(33)의 누전이나 과부하 또는 단락 등에 의한 전기적인 감전사고 등을 방지하도록 누전차단기(34)가 내장되며, 이 누전차단기(34)의 일측에는 상기 조명모듈(33)에 의해 빛이 조사될 때에 그와 동시에 알림음을 발생시켜 작업자의 주의를 환기시키도록 된 부저(35)가 내장된 것이다.1 and 2 show a preferred embodiment of the present invention. As shown in Figure 1, the auto light 30 of the present invention is provided with a light box 31 in the form of a box of a certain size, and the light projection in the form of a plate of a transparent material on the front of the light box 31. The panel 32 is coupled so as to be able to open and close, and in the lighting box 31, a lighting module 33 including an LED lighting panel 33a and a ballast 33b for irradiating light through the light-transmitting panel 32 ) is installed, and an earth leakage breaker 34 is built in to prevent electric shock accidents caused by leakage, overload, or short circuit of the lighting module 33, and on one side of the earth leakage breaker 34, the lighting module 33 ), when light is irradiated, a buzzer 35 is built-in to arouse the attention of the operator by generating a notification sound at the same time.

이러한 조명박스(31)는 피트(11) 상에 설치되어 작업자의 진입시에 조명을 비추도록 설치되는데, 이를 도 2를 더하여 설명하면 다음과 같다. This lighting box 31 is installed on the pit 11 to illuminate the light when the operator enters, which will be described by adding FIG. 2 as follows.

도 2에 도시된 바와 같이, 본 발명의 조명박스(31)는 엘리베이터의 승강카가 수직으로 이동되는 최하층의 피트(11) 벽면 상에 고정 설치되어 승강장 도어(10)의 개방과 동시에 작업자가 별도의 조명작업없이 자동적으로 조명을 비추어 안전하게 시야를 확보하도록 된 것으로, 통상적으로 피트(11) 내에서의 작업을 위해서는 엘리베이터가 작동되는 최하층의 승강장 도어(10)를 개방하여 사다리(12) 등에 의해 피트(11)의 바닥으로 진입하게 된다.As shown in Fig. 2, the lighting box 31 of the present invention is fixedly installed on the wall of the pit 11 of the lowest floor where the elevator car is vertically moved, and at the same time as the platform door 10 is opened, the operator can separate it. It is designed to secure a safe view by automatically illuminating without lighting work. In general, for work in the pit 11, open the platform door 10 of the lowest floor where the elevator is operated, and use the ladder 12, etc. to pit ( 11) enters the bottom.

이를 위해, 본 발명은 승강장 도어(10)를 개방작동을 인식하도록 된 개폐인식수단(40)이 구비된 것으로, 상기 개폐인식수단(40)은 다양한 감지형태로 구비되어 승강장 도어(10)의 배면측에 브라켓으로 고정 설치될 수 있는데, 이러한 개폐인식수단(40)의 일례로는 상기 승강장 도어(10)가 닫힌 상태에서 접점이 접촉 유지되고, 승강장 도어(10)가 개방될 때에 접점이 이격되는 스위치 타입으로 구비될 수 있고, 이 개폐인식수단(40)은 조명박스(31) 상에 케이블 등에 의해 전기적으로 연결되어 상기 조명모듈(33)의 작동을 제어할 수 있도록 된 것이다.To this end, the present invention is provided with an opening/closing recognition means 40 for recognizing the opening operation of the landing door 10, and the opening/closing recognition means 40 is provided in various sensing types, so that the rear surface of the platform door 10 is provided. It can be fixedly installed on the side with a bracket. An example of such opening/closing recognition means 40 is that the contact points are maintained in a closed state when the platform door 10 is closed, and the contacts are spaced apart when the landing door 10 is opened. It may be provided as a switch type, and the opening/closing recognition means 40 is electrically connected to the lighting box 31 by a cable or the like to control the operation of the lighting module 33 .

이러한 본 발명은 엘리베이터의 점검이나 유지보수 작업 등을 위해 작업자가 피트(11) 내로 진입할 때에 조명을 밝히도록 된 것이므로, 정상적으로 엘리베이터가 운행되는 과정에서 승강카 도어와 승장장 도어(10)가 동시에 열릴 때에는 굳이 조명을 비출 필요가 없는 것이며, 이를 위해 본 발명에서는 엘리베이터의 작동과정에서 승강카가 도착됨을 감지할 수 있는 리미트스위치(50)를 설치할 수 있는 것이다.Since the present invention is to illuminate the light when an operator enters the pit 11 for inspection or maintenance work of the elevator, the elevator car door and the landing door 10 are simultaneously operated in the process of the normal elevator operation. When it is opened, there is no need to illuminate it, and for this purpose, in the present invention, it is possible to install the limit switch 50 that can detect the arrival of the elevator car during the operation of the elevator.

이러한 리미트스위치(50)는 통상적으로 승강카가 최하층에 정상적으로 착상되는 위치를 감지하기 위한 리미트스위치(14,15)가 설치되는 레일(14) 상에 추가적으로 설치되는 것으로, 본 발명의 리미트스위치(50)는 조명박스(31)와는 별도로 피트(11)의 레일(13) 상에 설치되어 조명모듈(33)에 전기적으로 연결된 것이며, 이에 의해서는 승강카가 운행되는 과정에서 승강장 도어(10)가 열리는 경우에도 조명모듈(33)의 작동이 되지 않아 전력소모나 부품의 수명저하나 열화 등을 줄일 수 있을 뿐만 아니라 상기 부저(35)에 의해 알림음이 발생되는 것도 방지하게 된다.This limit switch 50 is typically additionally installed on the rail 14 on which the limit switches 14 and 15 for detecting the position where the elevator car is normally implanted on the lowest floor, the limit switch 50 of the present invention. is installed on the rail 13 of the pit 11 separately from the lighting box 31 and electrically connected to the lighting module 33, whereby even when the platform door 10 is opened while the elevator car is operating Since the lighting module 33 does not work, it is possible to reduce power consumption, reduction in the lifespan or deterioration of components, and the like, and also prevent the alarm sound from being generated by the buzzer 35 .

이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의해 한정되는 것이 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 명백할 것이다.The present invention described above is not limited by the above-described embodiments and the accompanying drawings, and it is common in the technical field to which the present invention pertains that various substitutions, modifications and changes are possible within the scope without departing from the technical spirit of the present invention.
