Abstract

The utility model discloses a pitch angle measuring device of a bucket wheel machine, which relates to the technical field of angle measurement of bucket wheel machines and comprises a connecting circular tube fixedly connected to the side surface of a pitch arm of the bucket wheel machine, a mounting ring is fixedly connected onto the connecting circular tube, and a mounting shaft is rotatably connected onto the mounting ring. According to the utility model, by adopting the coaxial design of the encoder, the connecting circular tube and the mounting shaft, the accuracy of measurement is ensured, and by utilizing the matched arrangement of the lead weight and the double-thread screw, automatic adjustment can be realized when the side wall of the bucket wheel machine performs pitching action, the double-thread screw is kept vertically downward all the time, errors caused by the self weight of the device are reduced, and the working efficiency is improved. A second protective cover and a detachable protective assembly are arranged, so that the internal structure is effectively protected from being influenced by the external environment, the interference of environmental factors such as dust and moisture on the measurement precision is reduced, the stability of the device is improved, and the service life of the device is prolonged.
