PROBLEM TO BE SOLVED: To provide a bridge girder inspection device, manufacturable at low cost, and capable of simply inspecting a bridge girder.SOLUTION: A bridge girder inspection device comprises a levitation gas storage bag 11 for storing gas smaller in specific gravity than air, a frame body 12 for joining this levitation gas storage bag, an upper abutting part 13 supported by the frame body and butted against an under surface of a bridge girder 2 by levitation force acting from the levitation gas storage bag and a camera 14 for photographing the bridge girder in a state where the upper abutting part is butted against the under surface of the bridge girder, and also comprises an operation string 15 of which one end is joined to the levitation gas storage bag or the frame body and the other end is held by an operator of staying on the ground or an operator staying on the bridge girder. A travel wheel 16 for traveling along an under surface of the bridge girder is provided in a part for contacting with the bridge girder of the upper abutting part. A state of the bridge girder is photographed by the camera by traveling on the under surface in a state of abutting on the under surface of the bridge girder by levitating with the levitation gas.
【課題】少ない費用で製作することができ、橋桁を簡単に点検することができる橋桁点検装置を提供する。【解決手段】空気より比重の小さい気体を収容する浮揚気体収容袋１１と、この浮揚気体収容袋が結合される枠体１２と、枠体に支持されて前記浮揚気体収容袋から作用する浮揚力によって橋桁２の下面に突き当てられる上方当接部１３と、上方当接部が橋桁の下面に突き当てられた状態で、該橋桁を撮影するカメラ１４と、を備えるものとする。また、浮揚気体収容袋又は枠体に一端が結合され、他端が地上にいる操作者、又は橋桁上にいる操作者よって把持される操作紐１５を有する。上方当接部の橋桁と接触する部分には、橋桁の下面に沿って走行する走行車輪１６を設ける。浮揚気体によって浮揚し、橋桁の下面に当接された状態で下面を走行し、カメラで橋桁の状態を撮影する。【選択図】図１
