The present invention relates to a fixing device of a lower apparatus for a railroad vehicle and, more specifically, the device comprises: a vehicle body bracket installed in a lower side of a railroad vehicle; an apparatus bracket installed in an upper side of a lower apparatus to be inserted into the vehicle body bracket; a connecting member being interposed between the vehicle body bracket and the apparatus bracket to support the apparatus bracket inserted inside the vehicle body bracket using the vehicle body bracket; and a fixing bolt and nut by which the apparatus bracket inserted inside the vehicle body bracket and the connecting member are fixated to the vehicle body bracket. According to the invention, the lower apparatus is equipped on the lower side of the railroad vehicle using the vehicle body bracket, the apparatus bracket, and the connecting member; thereby saving work time and workspace required for the equipment of the lower apparatus, a musculoskeletal injury of the worker′s arm and a safety accident due to a dropping of the lower apparatus can be prevented as the worker does not have to lift the lower apparatus for a long time as the work time is reduced, and the impact due to a quick start and a sudden stop of the railroad vehicle and the load of the lower apparatus are spread over the vehicle body bracket, the apparatus bracket, and the connecting member such that breakage of a fastening bolt due to stress concentration can be prevented.

    본 발명은 철도차량용 하부기기 고정장치에 관한 것으로, 특히 철도차량의 하부에 설치되는 차체브래킷과, 하부기기의 상부에 상기 차체브래킷의 내부에 삽입되도록 설치되는 기기브래킷과, 상기 차체브래킷의 내부에 삽입되는 상기 기기브래킷을 상기 차체브래킷에 지지되도록 하기 위해 상기 차체브래킷 및 기기브래킷에 사이에 개재되는 연결부재와, 상기 차체브래킷의 내부에 삽입되는 상기 기기브래킷 및 연결부재를 상기 차체브래킷에 고정하는 체결볼트와 너트를 포함하여 이루어짐으로써, 하부기기가 차체브래킥과 기기브래킷 및 연결부재를 통해 철도차량의 하부에 장착됨에 따라 하부기기 장착에 따른 작업공간의 최소화 및 작업시간의 단축을 이룰 수 있고, 또 작업시간이 단축됨에 따라 하부기기를 장시간 들어올리지 않아도 되므로 작업자의 팔 근골격계의 부상과 하부기기의 떨어뜨림으로 인한 작업자의 안전사고를 예방할 수 있으며, 또한 철도차량의 급출발 및 급제동으로 인한 충격 및 하부기기의 하중이 차체브래킥과 기기브래킷 및 연결부재에 분산됨에 따라 종래 응력집중으로 인한 체결볼트의 파손을 방지할 수 있는 특출한 발명이다.
