WORK MACHINE ROTATION ANGLE DETECTION DEVICE
To provide a rotation angle detection device for a work machine and the like that are hard to be impacted by sediment and the like, and can more accurately detect a rotation angle of a movement unit relative to a main body unit.SOLUTION: A rotation angle detection device 30 comprises: a distance measurement sensor 32 that is rotatable around a reference axis together with an upper rotary body, and measures a distance to a measurement object; a reflector 31 that is rotatable around the reference axis together with a lower rotary body, provided with a space apart from the distance measurement sensor 32, and has a lateral face part 131 serving as the measurement object in which a distance between the distance measurement sensor 32 and the reflector continuously or discontinuously varies during one rotation around the reference axis; a storage unit 34 that stores data associating a distance from the distance measurement sensor 32 to the lateral face part 131 during one rotation of the reflector 31 around the reference axis with a rotation angle of the lower rotary body around the reference axis relative to the upper rotary body; and a control unit 35 that acquires a rotation angle of the lower rotary body on the basis of the distance measured by the distance measurement 32, and the data stored in the storage unit 34.SELECTED DRAWING: Figure 3
【課題】土砂等の影響を受けにくく、本体部に対する移動部の回転角度をより正確に検出できる作業機械の回転角度検出装置を提供すること。【解決手段】回転角度検出装置３０は、上部回転体と共に基準軸回りに回転可能であり、測定対象物までの距離を測定する距離測定センサ３２と、下部回転体と共に基準軸回りに回転可能であり、距離測定センサ３２と離間して設けられ、基準軸回りに１回転する間に距離測定センサ３２との間の距離が連続又は不連続に変化する測定対象物としての側面部１３１を有する反射体３１と、反射体３１が基準軸回りに１回転する間の距離測定センサ３２から側面部１３１までの距離と前記上部回転体に対する前記下部回転体の基準軸回りの回転角度とを対応付けたデータを記憶する記憶部３４と、距離測定センサ３２で測定された距離と前記記憶部３４に記憶されたデータとに基づいて、前記下部回転体の回転角度を取得する制御部３５とを備える。【選択図】図３
