VEHICLE UNDERFLOOR PART INSPECTION DEVICE

PROBLEM TO BE SOLVED: To provide a vehicle underfloor part inspection device equipped with an inspection device for inspecting an underfloor part of a vehicle on rails that can run along the rails between the rails that can accurately grasp its posture and position so that it can efficiently run between the rails.SOLUTION: A vehicle underfloor part inspection device includes a detection device for detecting a positional relationship with a predetermined object, and a control device 12 for grasping a posture based on the result of detection by the detection device. As the detection device, two or more distance measurement devices (distance measurement sensors 17) for measuring a distance from a side part to a rail 50 are provided at one side along a running direction at predetermined intervals. The control device 12 grasps a position with respect to the rail 50 and an angle in the running direction with respect to the rail 50 based on the result of measurement by the distance measurement devices.SELECTED DRAWING: Figure 5 【課題】レールの間を前記レールに沿って走行可能であり、レール上の車両の床下を検査するための検査装置を備えた車両床下検査装置において、自身の姿勢や位置を正確に把握できるようにし、レールの間を効率よく走行できるようにする。【解決手段】所定の対象物との位置関係を検出する検出装置と、検出装置による検出結果に基づき姿勢を把握する制御装置１２と、を備え、検出装置として、側部からレール５０までの距離を測る測距装置（測距センサ１７）を、一側部に走行方向に沿って所定の間隔を置いて２以上備え、制御装置１２は、測距装置による測定結果に基づきレール５０に対する位置及びレール５０に対する走行方向の角度を把握する。【選択図】図５
