Embodiment Construction

[0043] The embodiment of the present application provides a method for automatically adjusting the power balance of a long-distance conveying tape machine. The long-distance conveying tape machine adopts a hydraulic motor head-to-tail cooperative drive mode, mainly driven by the head motor, referring to the oil pressure ratio of the head and tail motors, Use the controller of the motor itself to adjust the speed of the tail motor so that it is balanced with the output speed of the nose motor. Because there is a certain relationship between the power of the motor and its output speed, the output speed of the head and tail motors is balanced. Therefore, the power of the nose and tail reaches Balanced state, thereby improving the stability and reliability of the system operation.

[0044] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be ...

Abstract

The invention discloses a method and system for regulating power balance of a remote adhesive tape conveying machine. The remote adhesive tape conveying machine adopts a hydraulic motor head-tail cooperation drive mode. The method for regulating the power balance comprises the steps of: respectively obtaining operation parameters of a machine head motor and a machine tail motor, wherein the operation parameters comprise oil pressure values and rotating speeds of the machine head motor and the machine tail motor; determining the oil pressure proportion of the machine head motor and the machine tail motor; when the oil pressure is not in a preset range, determining the expect rotating speed of the machine tail motor according to the oil pressure proportion and the rotating speed of the machine head motor; and regulating the rotating speed of the machine tail motor to the expect rotating speed by using a proportion integral derivative regulating mode. Compared with the prior art, the invention can improve the operation stability and reliability of the remote adhesive tape conveying machine and enhance the production efficiency.

Description

technical field [0001] The present application relates to the technical field of automatic control, in particular to a method and system for automatically adjusting the power balance of a long-distance conveyor belt conveyor. Background technique [0002] With the rapid development of the global industry, the application of long-distance conveyor belt conveyors is becoming more and more extensive to realize long-distance conveying of materials. [0003] At present, the long-distance conveying belt machine generally adopts the frequency converter drive method. However, in the long-term application process, due to the frequent load changes of the long-distance conveying belt machine, and the frequency converter has no self-adjusting function and poor synchronization, it cannot be used for long-distance conveying. The head-to-tail power of the tape machine is reasonably matched, so the power balance adjustment effect of the long-distance conveyor belt machine driven by the freq...
