Embodiment Construction

[0010] A process overload control device for a ship unloader and a belt conveyor, comprising a control code unit, a frequency converter for a vibrating feeder, a programmable controller for a belt conveyor, a programmable controller for a ship unloader, an optical fiber and a switch. The programmable controller of the belt conveyor communicates with the programmable controller of the ship unloader in the form of optical fiber through the switch, and the programmable controller of the ship unloader controls the output of the frequency converter of the vibrating feeder through the control program. The data used include: belt conveyor instantaneous flow signal (real number type), normal mode detection delay time (time type), vibration feeder manual control mode lock switch (Boolean type), driver's cab operation interface alarm prompt (Boolean type), Lock mode overload detection delay time (time type), lock mode normal detection delay time (time type), frequency drop detection dela...

Abstract

The invention relates to a ship unloader and belt conveyor process overload control method and belongs to the technical field of ship unloader and belt conveyor electrical control methods. According to the technical scheme, the control method includes the steps that firstly, signal collection is conducted, wherein a belt conveyor instantaneous flow rate signal is input into a ship unloader programmable controller by a belt conveyor programmable controller via an opc communication mode; secondly, signal processing is conducted, wherein the belt conveyor instantaneous flow rate signal is led into a vibration feeder motor control program of the unloader programmable controller; and thirdly, the programmable controller conducts logical judgment, and output includes adjusting of the manual modelocking on-off state of a vibration feeder motor, alarm prompting of an operation interface of a cab, automatic lowering of a frequency set value and lowering of the running frequency of the vibration feeder motor. By means of the ship unloader and belt conveyor process overload control method, flow overload of the belt conveyor is prevented, the phenomenon that the belt conveyor is overloaded for a long time, and consequently production accidents are probably caused is avoided, equipment damage and losses caused by long-time overload of the belt conveyor are reduced, the overload respondingefficiency of the belt conveyor is improved, flow fluctuation of the belt conveyor is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a process overload control method for a ship unloader and a belt conveyor, and belongs to the technical field of electrical control methods for ship unloaders and belt conveyors. Background technique [0002] At the bulk cargo terminal where the ship unloader undertakes the unloading function, the cabin materials grabbed by the ship unloader are transported to the storage yard through the belt conveyor. The material flow rate of the belt conveyor depends on the type of cargo and the discharging speed of the vibrating feeder of the ship unloader, and the discharging speed of the vibrating feeder is determined by the motor frequency of the vibrating feeder of the ship unloader. When multiple ship unloaders work on the same belt conveyor under the same cargo condition, the belt flow rate depends on the motor frequency of the vibrating feeder of all ship unloaders. [0003] Currently, the frequency of the vibrating feeder of the s...
