Through the connection relationship between the first replacement rod 406 and the hinged plate 302, the plate hammer can be buffered during rotation, and torque is generated on the first replacement rod 406 and the second replacement rod 407, which is beneficial to improve the stability of the device. The external circuit mechanism enables the second motor 307 to work, and the second motor 307 drives the first gear 308 to rotate. Since the first gear 308 is meshed with the first external gear 306 for transmission, the threaded cylinder 305 rotates on the outer wall of the screw rod 303 through the internal thread, wherein the screw rod 303 is moved downward by the first thread to adjust the height of the clamping structure, and then the second gear 315 is driven by the third motor 314 to make the second external gear 312a meshed for transmission, wherein the transmission cylinder 312 rotates, so that the curved rod 312b applies a force to the limit frame 401, thereby adjusting the angle of the replacement structure.

It is worth noting that the cylinder 4 13 is a conventional device in the prior art, and the push plate 405 can be pushed to move to one side by the cylinder 413, so that the first replacement rod 406 and the second replacement rod 407 can be more easily inserted on the plate hammer. The present invention can increase the friction between the device and the plate hammer by setting the support rod 411, and can effectively prevent the plate hammer from causing wear to the parts on the device, which is beneficial to improving the service life of the device.

At this time, the first replacement rod 406 and the second replacement rod 407 are respectively inserted into the holes on both sides of the plate hammer, wherein, when the first When the replacement rod 406 is inserted into the plate hammer hole, the support rod 411 is adjusted in the hole so that the support rod 411 fits with the inner wall of the plate hammer hole, thereby increasing the friction between the first replacement rod 406 and the plate hammer, and then the cylinder 413 is used to move the plug plate 405 in the opposite direction, thereby achieving the effect of clamping the plate hammer. Then, the staff removes the bolts on the plate hammer, and the driving components of the lifting structure work to move the plate hammer upward. Since both sides of the plate hammer can be crushed, at this time, the fourth motor 408 is operated through the external circuit mechanism, and the fourth motor 408 drives the first replacement rod 406 to rotate, so that the plate hammer is turned over on the replacement frame 404 through the first replacement rod 406 and the second replacement rod 407, and the curved rod 312b is driven to rotate through the third motor 314.The curved rod 312b exerts a force on the limit frame 401 to rotate, thereby realizing the function of the plate hammer rotation, and then the plate hammer is fixedly installed on the roller shaft by bolts.

At this time, the first changing rod 406 and the second changing rod 407 are respectively inserted into the holes on both sides of the plate hammer. When the first changing rod 406 is inserted into the plate hammer hole, the support rod 411 is adjusted in the hole so that the support rod 411 fits with the inner wall of the plate hammer hole, thereby increasing the friction between the first changing rod 406 and the plate hammer. Then, the cylinder 413 is used to move the pressing plate 405 in the opposite direction, thereby achieving the effect of clamping the plate hammer. Then, the staff removes the bolts on the plate hammer, and the driving components of the lifting structure work to move the plate hammer upward. Since both sides of the plate hammer can work in crushing, at this time , the fourth motor 408 is operated through an external circuit mechanism, and the fourth motor 408 drives the first replacement rod 406 to rotate, so that the plate hammer is turned over on the replacement frame 404 through the first replacement rod 406 and the second replacement rod 407, and the third motor 314 drives the curved rod 312b to rotate, so that the curved rod 312b exerts a force on the limit frame 401 to rotate, thereby realizing the function of plate hammer rotation, and then the plate hammer is fixedly installed on the roller shaft by bolts. When a new plate hammer needs to be replaced, the plate hammer in the impact crusher is first taken out from the roller shaft, and then the new plate hammer is installed on the roller shaft in the impact crusher through the device.

[0040] Step S3: Based on the energy consumption analysis results in step S2, the control strategy is adjusted according to the working conditions of each motor; if the energy consumption of a motor is high but the actual workload is not large, the control system can adjust the motor's operating frequency or start the energy-saving mode to reduce energy consumption; if the energy consumption of a motor fluctuates abnormally, the system will issue an early warning and notify maintenance personnel to check the motor or related components to avoid equipment downtime or further damage; if the load of a motor is too high, the system can adjust the task allocation and reasonably distribute the load to other motors to avoid overload

[0041] Step S4: After acquiring and analyzing the energy consumption data of the motors, the system can automatically adjust the working mode of each motor through a control program.

[0042] In this embodiment, the energy consumption data collected in step S1 is analyzed in real time and the working status of each motor is evaluated. When a potential abnormality is found, the threshold of the ADI value of the motor is first preset, and then the formula ΔE is used. i (t) = E i (t)-E i (t-1) Calculate the energy consumption change rate of each motor to reflect whether the motor's workload is within a reasonable range, where ΔE i (t) represents the energy consumption change rate of the i-th motor at time t, reflecting the increase or decrease trend of the motor's energy consumption;

[0043] In order to judge the working status of the motor, the energy consumption mean and standard deviation of each motor are used for evaluation. In the detection process, the abnormality detection index is used to evaluate whether the motor is abnormal by comprehensively considering the energy consumption change rate, mean and standard deviation. The expression is: Among them, ADI is an indicator used to comprehensively evaluate whether the energy consumption of the motor is normal. i (t)| represents the change in energy consumption at the current moment, μ i is the mean value, reflecting the normal working energy consumption range of the motor, σ i It is the standard deviation, which reflects the fluctuation range of the energy consumption during the operation of the motor. The higher the ADI value, the greater the fluctuation of the motor's energy consumption, and the more likely it is to be abnormal. i (t)≤ADI threshold, it indicates that the motor has a potential abnormality
