The rapid development of foreign belt conveyor technology is mainly manifested in two aspects: on the one hand, the function of the belt conveyor is diversified and the application range is expanded, such as high inclination belt conveyor, tubular belt conveyor, space Turning belt conveyors and other various models; on the other hand, the technology and equipment of belt conveyors have developed tremendously, especially large belt conveyors such as long-distance, large-capacity, and high-speed belt conveyors have become The main direction of development, its core technology is the development and application of dynamic analysis and monitoring technology of belt conveyors, which improves the performance and reliability of belt conveyors. At present, the key technologies and equipment of belt conveyors used in coal mines have the following characteristics:
⑴ Large-scale equipment. Its main technical parameters and equipment are developing towards large-scale development to meet the needs of high-yield, high-efficiency and intensive production with an annual output of more than 3 to 5 million tons.
⑵The application of dynamic analysis technology, mechatronics, computer monitoring and other high-tech, adopts high-power soft start and automatic tensioning technology to dynamically monitor and monitor the conveyor, which greatly reduces the dynamic tension of the conveyor belt, and the equipment has good operating performance , High transportation efficiency.
(3) The use of multi-machine drive and intermediate drive and its power balance, conveyor changing direction operation technology, so that the length of the single conveyor running is theoretically limited, and ensures the versatility, interchangeability and unit of the conveying system equipment Reliability of the drive.
⑷New, high-reliability key component technology. Such as various advanced high-power driving devices and speed regulating devices, including CST, etc., long-life high-speed idlers, self-cleaning roller devices, high-efficiency belt storage devices, fast self-moving tails, etc. For example, the FSW1200/(2~3)×400(600) working face along the groove belt conveyor produced by FSW in the United Kingdom adopts a liquid-viscous differential speed or variable frequency speed control device, and the transportation capacity is more than 3000 t/h. The tail is matched with a new type of transfer machine (such as the S500E produced by Joy Company in the United States), which can automatically and quickly move with the progress of the working surface, with less manual operations and high production efficiency.
