Abstract

The invention discloses a rotation angle detecting device and a crane, and relates to the technical field of engineering machines. The device comprises a base, an encoder and a rotation gear. The encoder is arranged in the base, and comprises an encoder body and a transmission spindle which are in transmission connection, the rotation center of the rotation gear is fixedly connected with the transmission spindle, and the rotation gear is used for being in engaging transmission with a rotation mechanism. The detection precision of the rotation angle can be improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a rotation angle detection device and a crane. Background technique [0002] With the improvement of the intelligence level of modern construction machinery, the high-precision detection of the state of construction machinery itself is becoming more and more important. The detection of the rotation angle is also crucial to the control and safety performance of construction machinery. The rotation angle detection device is directly related to the measurement of the rotation angle. Therefore, the reliability and accuracy of the rotation angle detection device are the most critical elements for the accurate control of the construction machinery rotation device. [0003] In the prior art, the detection of the rotation angle of construction machinery is generally to install a rotary conductive ring at the center of the two opposite rotary mechanisms. In addition to tran...
