도 1 및 도 2를 참조하여 종래기술에 따른 전동차 플랫폼 안전장치를 살펴보면, 종래기술은, 전동차가 진입하는 플랫폼의 입구로부터 출구의 선택된 위치에 적어도 한 쌍 이상의 본체(20)가 설치되고, 쌍을 이루는 본체(20) 각각에 구동유닛(40)의 작동에 의하여 본체(20)를 따라 상하방향으로 이동하는 좌우방향 양쪽의 이동블록(30)이 설치되며, 양쪽의 이동블록(30)이 차단부재(50)인 로프에 의하여 서로 연결된다.Looking at the electric vehicle platform safety device according to the prior art with reference to Figures 1 and 2, in the prior art, at least one or more pairs of the main body 20 is installed at a selected position of the exit from the inlet of the platform into which the electric vehicle enters, the pair In each of the constituent bodies 20, moving blocks 30 in both the left and right directions moving vertically along the main body 20 by the operation of the driving unit 40 are installed, and both moving blocks 30 are blocking members. 50 is connected to each other by a rope.
그러나, 종래기술에 따른 전동차 플랫폼 안전장치는, 도 2에 도시된 바와 같이, 차단부재(50)가 양쪽의 이동블록(30) 사이에 항시 팽팽하게 긴장된 상태로 유지되기 때문에, 본체(20), 이동블록(30)의 상하이동을 유도하는 레일 등이 내측으로 당겨지면서 본체(20), 레일 등에 내측으로 휘어지는 변형이 발생하여 내구성 및 사용 수명이 단축되는 문제가 있다.However, the electric vehicle platform safety device according to the prior art, as shown in Figure 2, since the blocking member 50 is always kept in a tense state between the two moving blocks 30, the main body 20, As the rails for inducing the shank movement of the moving block 30 are pulled inward, deformation occurs to the inside of the main body 20, the rails, etc., resulting in shortening of durability and service life.
