Description
본 고안은 전동차 출입문 안전발판에 관한 것으로, 더욱 구체적으로 전동차가 정차 시에 출입문과 승강장사이의 간격으로 인해 발생할 수 있는 안전사고를 미연에 방지하기 위해 전동차의 출입문 측에 설치하여 승객이 안전하고 용이하게 승하차할 수 있게 한 전동차 출입문 안전발판에 관한 것이다.The present invention relates to an electric vehicle door safety scaffold, and more specifically, to prevent the safety accidents that may occur due to the gap between the door and the platform when the vehicle is stopped, it is installed on the entrance side of the electric vehicle to make the passenger safe and easy. It relates to an electric vehicle door safety step that allows you to get on and off.
일반적으로 전동차는 여러 개의 차량이 연속적으로 연결되어 있어 정차할 경우 승강장과 전동차와의 간격은 필연적으로 발생되는 것이고, 곡선 승강장에서는 전동차와의 간격이 더욱 벌어져 승객의 발이 끼워지거나 승객들의 휴대품이 끼워져 안전사고를 유발하였던 것이다.In general, electric vehicles are connected to several vehicles in series, so when the vehicle stops, the distance between the platform and the train is inevitably generated. It caused an accident.
이러한 문제점을 해결하기 위하여 여러 종류의 안전발판이 개발되었고, 그 중 전자제어회로를 채택한 것은 구조가 복잡하고 제작비용이 많이 소요되며 전자제어 방식은 어제나 오동작이나 고장을 일으킬 수 있는 문제점을 내포하고 있는 것이며, 또한 선 출원된 실용신안등록출원 20-2002-0004589 전동차 출입구의 승강판의 경우 도르래와 와이어로 작동되게 구성된 것으로 와이어의 얽힘이나, 늘어난 와이어로 인해 도르래에서 이탈하는 문제점을 예견할 수 있는 것이다.In order to solve these problems, various types of safety scaffolds have been developed. Among them, the electronic control circuit adopts a complicated structure and a high manufacturing cost, and the electronic control method includes problems that may cause malfunction or failure yesterday. In addition, the utility model registration application 20-2002-0004589 previously applied for the lifting plate of the electric vehicle entrance is configured to be operated by the pulley and the wire, which can predict the problem of deviating from the pulley due to the entanglement of the wire or the increased wire. will be.
한편, 전동차가 아닌 승강장에 안전발판을 설치하는 경우는 이 역시 공사하기가 불편하고 구조가 복잡해지는 문제점이 있는 것이다.On the other hand, if the safety scaffolding is installed in the platform rather than the electric car is also a problem that the construction is inconvenient and complicated structure.
본 고안은 전기한 문제점을 해결하기 위하여 안출한 것으로, 전동차의 출입문 안쪽에 래크와 피니언, 웜과 웜휠을 구성하여 별도의 동력 없이 출입문의 개폐 작동되는 동력으로 안전발판을 상하로 구동되게 함으로서 전동차와 승강장의 간격을 없애 승객의 발이 빠지지 않게 하여 안전사고를 미연방지하고, 구성이 간단하며, 작동을 원활하게 한 전동차 출입문 안전발판을 제공하기 위한 것이다.The present invention has been devised to solve the above-mentioned problems, by configuring the rack and pinion, the worm and the worm wheel inside the door of the electric car to drive the safety scaffold up and down by the power to open and close the door without additional power. The purpose of the present invention is to provide an electric door safety footrest that prevents safety accidents by removing the gap of the platform so as to prevent the passenger's foot from falling out, and the configuration is simple and the operation is smooth.

미 설명부호 8은 실린더이다Reference numeral 8 is a cylinder.
이와 같은 본 고안에 따른 전동차 출입문 안전발판의 작용효과를 설명하면 다음과 같다.Referring to the effect of the electric vehicle door safety scaffold according to the present invention as follows.
본 고안은 전동차(1)의 출입문(2)이 닫힌 상태에서는 안전발판(7)이 출입문(2)에 밀착된 상태로 가로질러 있어 전동차(1)의 운행에 에는 아무런 지장을 주지 않는 것이다.According to the present invention, when the door 2 of the electric vehicle 1 is closed, the safety scaffold 7 is in close contact with the door 2 and thus does not interfere with the operation of the electric vehicle 1.
이러한 상태에서 전동차(1)가 승강장 내로 진입되어 출입문(2)이 실린더(8)에 의해 열리면 출입문(2)에 연결 구성된 래크기어(3)가 출입문(3)의 슬라이딩 작동과 같은 방향으로 밀리게된다.In this state, when the electric vehicle 1 enters the platform and the door 2 is opened by the cylinder 8, the rack gear 3 connected to the door 2 is pushed in the same direction as the sliding operation of the door 3. Will be.
래크기어(3)가 작동되어 밀리면 래크기어(3)에 이맞물려있는 피니언기어(41)가 회전 운동하게 되고 피니언기어(41)의 회전력은 구동축(4)에 의해 웜기어(43)에 전달되어 웜기어(43)가 회전하게된다.When the rack gear 3 is operated and pushed, the pinion gear 41 meshed with the rack gear 3 rotates and the rotational force of the pinion gear 41 is transmitted to the worm gear 43 by the drive shaft 4. The worm gear 43 is rotated.
웜기어(43)의 회전력은 이맞물려있는 부채꼴 웜휠기어(51)에 전달되어 부채꼴 웜휠기어(51)에 의해 회전 방향이 전환된다.The rotational force of the worm gear 43 is transmitted to the fan-shaped worm wheel gears 51 engaged with each other so that the rotation direction is switched by the fan-shaped worm wheel gears 51.
부채꼴 웜휠기어(51)의 회전력은 작동축봉(5)에 전달되어 스프링(61)으로 탄지 되어 작동축봉(5)에 끼워져 있는 작동간(6)에 전달되어 작동간(6) 결합되어 있는 안전발판(7)을 회동시켜 승강장과 전동차(1)간의 사이공간을 덮어주는 것이다.The rotational force of the fan-shaped worm wheel gear 51 is transmitted to the operating shaft rod 5 and is supported by the spring 61 and transferred to the operating shaft 6 fitted to the operating shaft rod 5 to be coupled to the operating shaft 6. (7) is rotated to cover the space between the platform and the electric vehicle (1).
승강장의 높이 차이에 따른 안전발판(7)의 개폐유격은 상기 스프링(61)의 양단이 작동축봉(5)의 걸고리(52)와 작동간(6)의 걸림구(62)에 걸려 탄지 되어 작동간(6)을 회동시키므로 안전발판(7)의 개폐유격을 흡수 있는 것이다.The opening and closing play of the safety scaffold 7 according to the height difference of the platform is operated by hanging both ends of the spring 61 caught by the hook 52 of the operating shaft 5 and the engaging port 62 of the operation 6. By rotating the liver (6) is to absorb the opening and closing play of the safety scaffold (7).
따라서, 승객은 안전발판(7)에 의해 발이 빠지지 않고 안전하게 승하차 할 수 있는 것이다.Therefore, the passenger can get on and off safely without the foot being pulled out by the safety step 7.
다시 전동차(1) 출발하기 위하여 출입문(2)이 닫히면 출입문(2)이 역방향으로 슬라이딩 작동됨에 따라 래크기어(3)는 출입문(2)이 열릴 때와 반대로 작동되고래크기어(3)에 이맞물린 피니언기어(41), 웜기어(43)와 이맞물린 부채꼴 웜휠기어(51)가 출입문(2)이 열릴 때와는 반대방향으로 회전되고 작동간(6)역시 역회전하여 안전발판(7) 원위치로 복귀시켜 전동차(1)는 안전 운행하는 것이다.When the door 2 is closed to start the electric vehicle 1 again, as the door 2 slides in the reverse direction, the rack gear 3 is operated in the opposite direction as when the door 2 is opened, and the rack gear 3 The engaged pinion gear (41) and the worm gear (43) are engaged with the fan-shaped worm wheel gear (51), which is rotated in the opposite direction as when the door (2) is opened, and during operation (6). By returning to the original position, the electric vehicle 1 runs safely.
이상에서 설명한 본 고안은 전술한 실시태양 및 도면에 의해 한정되는 것은 아니고, 본 고안의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 고안이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어 명백할 것이다.The present invention described above is not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be apparent to those who have
이상과 같은 본 고안에 따른 전동차 출입문 안전발판은 전동차 출입문과 승강장 사이 간격을 효과적으로 덮어주어 안전사고를 미연에 방지 할 수 있고, 별도의 동력 없이 출입문의 개폐작동으로 안전발판을 작동시키므로 구조가 단순하고 설치가 용이하며 기계식임으로 작동의 원활함과 고장수리가 용이한 이점이 있는 등 여러 효과가 있는 유용한 고안이다.Electric vehicle door safety scaffold according to the present invention can effectively cover the gap between the electric car door and the platform to prevent accidents in advance, and the structure is simple because the safety scaffold operates by opening and closing the door without additional power. It is a useful design with various effects, such as easy installation and mechanical advantages, such as smooth operation and easy troubleshooting.
