The invention discloses a bucket wheel machine and an anti-overload control method and device. The anti-overload control device of the bucket wheel machine comprises a frequency conversion motor, a frequency converter and a controller. Current output by a power supply device is supplied to the frequency conversion motor through the frequency converter, the frequency converter is used for adjusting current frequency and acquiring torque output by the frequency conversion motor, and the frequency conversion motor is used for driving a bucket wheel to rotate. The controller receives the torque detected by the frequency converter. When the torque is larger than the first preset torque, the controller controls the frequency converter to change the current frequency to further reduce the torque output by the frequency conversion motor. When the bucket wheel machine is overloaded or is going to be overloaded, the anti-overload control device can timely reduce the torque output by the frequency conversion motor to effectively protect the frequency conversion motor from overload to further ensure that the bucket wheel machine is safe and stable in operation.
Description
technical field [0001] The invention relates to bulk material stacking technology, in particular to a bucket wheel machine and its anti-overload control method and device. Background technique [0002] Bucket wheel stacker and reclaimer (also known as bucket wheel machine) is a common equipment for continuous loading and unloading of bulk materials in modern industry. Bulk materials (such as mines, coal, coke, sand and gravel) stacking operations in coal plants, power plants and other occasions. [0003] Usually, a bucket wheel stacker-reclaimer includes a cart mechanism, a bucket wheel, a slewing platform, a forearm frame and a slewing platform, and the slewing platform is rotatably arranged on the cart mechanism. Bucket wheel connection; in order to make the forearm pitch, a pitch cylinder is arranged between the rotary platform and the forearm frame, one end of the pitch cylinder is hinged with the forearm frame, and the other end of the pitch cylinder is hinged with the...
