PURPOSE: A transportable bridge inspecting device is provided to stably inspect a bridge pier, a bridge seat, a bottom surface of a bridge deck, and an inspection path of the bridge deck. CONSTITUTION: A transportable bridge inspecting device(100) comprises a plurality of first rail posts(110), a plurality of second rail posts(120,120'), a pair of vertical rails(130,130'), a pair of horizontal rails(140,140'), a moving unit(150), a connection post(160), and an inspection deck(170). The plurality of first rail posts is fixed to a bridge pier at a constant distance. The plurality of second rail posts is horizontally fixed to a bottom surface of a bridge deck at a constant distance. The pair of vertical rails is vertically installed in the first rail posts at a constant distance. The pair of the horizontal rails is horizontally installed in the second rail posts and connected to the vertical rail positioned higher than the other vertical rail. The moving unit moves the inspection deck along the horizontal rails and vertical rails by the rotation of a power transmission gear. The power transmission gear is joined to toothed gears of the horizontal and vertical rails. The connection post connects the moving unit and inspection deck. The inspection deck is fixed to the connection post. |
