Embodiment 1

[0048] Embodiment 1: A large-scale drive master-slave control device for a conveyor belt conveyor, the device includes a plurality of AC asynchronous motors 3, a conveyor belt synchronously driven by several AC asynchronous motors 3, and also includes driving each AC asynchronous motor 3, and the AC asynchronous motor 3 frequency converters with the same number, one of which is the main frequency converter 1, the power input terminal of each frequency converter is connected to the power grid, and the power output terminal is connected to the stator input terminal of the corresponding AC asynchronous motor 3; When the motor shafts of the AC asynchronous motor connected to the master inverter 1 and the AC asynchronous motor connected to the slave inverter 2 are rigidly connected, the AC asynchronous motor connected to the slave inverter outputs power at a constant torque so that there is no gap between the transmission units. speed difference (eg figure 1 shown). The AC asynchr...

Embodiment 2

[0050] Embodiment 2: as image 3 As shown, a method for operating a large-scale transmission master-slave control device of a conveyor belt conveyor, the method includes the following steps:

[0051] 1) Start the main inverter, after the parameters of the main inverter are set, the PLC programming and the man-machine interface configuration are completed, download the program to the PLC through the PROFIBUS network, and download the inverter parameters to the inverter;

[0052] 2) Before running each inverter for the first time, each inverter performs static and dynamic identification of the motor, and the speed link can be fine-tuned during actual operation;

[0053] 3) Before the system starts, the PLC main frequency converter checks whether all the protectors are normal. Firstly, each sensor detects various signals of the conveyor belt machine, from the state signal of the frequency converter, to the permission start signal of the conveyor belt connected before and after. A...

Abstract

The invention relates to material conveying equipment of industrial and mining enterprises, in particular to large-scale transmission master-slave control equipment of a belt conveyer and an operation method of the equipment. The equipment comprises multiple alternating-current asynchronism motors, a conveying belt synchronously driven by the multiple alternating-current asynchronism motors, and frequency converters used for driving all the alternating-current asynchronism motors and having the same number of the alternating-current asynchronism motors, wherein one of the frequency converters is a main frequency converter; power supply input ends of all the frequency converters are connected with a power grid, and power supply output ends are connected with stator input ends of the corresponding alternating-current asynchronism motors; the alternating-current asynchronism motor connected with the main frequency converter is rigidly connected with motor shafts of the alternating-current asynchronism motors connected with the slave frequency converters; the alternating-current asynchronism motors connected with the slave frequency converters output power by constant torque; the alternating-current asynchronism motor connected with the main frequency converter is flexibly connected with the alternating-current asynchronism motors connected with the slave frequency converters; and the slave frequency converters adopts a speed control mode.

Description

[0001] technical field [0002] The invention relates to material conveying equipment for industrial and mining enterprises, in particular to a large-scale drive master-slave control equipment for belt conveyors and an operating method for the equipment. Background technique [0003] In mining, metallurgy, coal and other industrial and mining enterprises, the transportation of materials is a very important process link, and the belt conveyor is the main transportation equipment. When the amount of materials to be conveyed is relatively large, multiple motors will drive the same belt. The transmission mode of the machine. [0004] With the improvement of industrial production automation and the expansion of production scale, the length and transmission power of various production conveyor lines continue to increase. When the length of the conveyor line increases to a certain extent (generally greater than 200 m), it is difficult to meet the requirements of a single motor ...
