The present invention relates to a center-installed catenary trolley fall prevention device. According to the present invention, a buffer frame is rotated by a first section operation of a driving unit to deploy the buffer to a catenary fall prevention position, and then a square latch pin is engaged with a latch groove by a second section operation of the driving unit to restrict the buffer frame. Accordingly, even if an impact force is applied to the buffer frame, the impact force is not directly transmitted to a driving device vulnerable to the impact. Accordingly, even if a situation in which a catenary trolley applies the impact force to the buffer occurs, the catenary trolley fall prevention device is very strong and reliable and does not lose its original function. The catenary trolley fall prevention device comprises a main frame (10), a buffer frame (20), a latch lifter module (30), and a driving module (100).

    본 발명은 Boom 중앙 설치형 캐트너리 트롤리 추락방지장치에 관련되며, 이는 구동부의 1차 구간 동작에 의해 버퍼프레임이 선회 작동되어 버퍼(Buffer)가 캐트너리 추락방지 위치에 전개되고, 이어서 구동부의 2차 구간 동작에 의해 스퀘어 래치핀이 래치홈에 맞물려 버퍼프레임이 구속되도록 구조 개선되어, 버퍼 프레임에 충격력이 작용하더라도 충격에 취약한 구동장치에 직접 충격력이 전달되지 않고, 이를통해, 캐트너리 트롤리가 버퍼에 충격력을 가하는 상황이 발생하더라도 캐트너리 트롤리 추락방지 장치는 본연의 기능을 잃지 않는 매우 견고하고 신뢰성 있으며, 메인프레임(10), 버퍼프레임(20), 래치리프터모듈(30)과 구동모듈(100)을 포함하여 주요 구성으로 한다.
