BRIDGE INSPECTION DEVICE

PROBLEM TO BE SOLVED: To provide a bridge inspection device that can suppress vibrations in an inspection part and be easily handled while also suppressing an increase in size and weight.SOLUTION: A bridge inspection device 10 comprises: a vertical arm 40; a horizontal arm 41 whose intermediate part is rotatably connected to a lower end of the vertical arm 40, and which has a first portion 41A arranged below a bridge 1 and a second portion 41B arranged on the outer side of the bridge 1; an inspection camera 45 which is installed on the first portion 41A, and inspects the bridge 1 from below; a counterweight 48 which is arranged below the second portion 41B; a first suspension member 49 which is extended from the counterweight 48 to the first portion 41A through a first pulley 46 installed on the second portion 41B and a second pulley 47 installed at a position higher than a connection part of the horizontal arm 41 of the vertical arm 40, and energizes the first portion 41A upward; and a strut 42 which is installed on the first portion 41A so as to protrude upward, and is abutted against a lower surface of the bridge 1.SELECTED DRAWING: Figure 1 【課題】大型化及び重量化を抑制しつつ点検部の揺れを抑制でき、取り扱いが容易な橋梁点検装置を提供する。【解決手段】橋梁点検装置１０は、鉛直アーム４０と、鉛直アーム４０の下端部に回動可能に中間部を結合され、橋梁１下方に配置された第１部分４１Ａ及び橋梁１外側に配置された第２部分４１Ｂを有する水平アーム４１と、第１部分４１Ａに設けられ、橋梁１を下方から点検する点検カメラ４５と、第２部分４１Ｂの下方に配置されるカウンタウェイト４８と、カウンタウェイト４８から、第２部分４１Ｂに設けられた第１滑車４６及び鉛直アーム４０の水平アーム４１との結合部よりも高い位置に設けられた第２滑車４７を通って第１部分４１Ａに張設され、第１部分４１Ａを上方に付勢する第１吊り材４９と、第１部分４１Ａに上方へ突出するように設けられ、橋梁１の下面に当接する束部４２とを備える。【選択図】図１
