Research On The Belt Conveyor With Super-Long Distance, High Angle And High Strength

With the more and more application of belt conveyor in coal mine, wharf, power station and other places, the needs for belt conveyor with super-long distance, high angle and high strength are more increasing, furthermore they are wanted to be safe and reliable, high automaticity, low operational expenses, in order to save the investment of fundamental construction.This paper research on the problems in the designing process of the belt conveyor with super-long distance, high angle and high strength from 4 aspects.Analyzing the calculating process of belt conveyor with high angle theoretically, starting from its theoretic calculate the cross sectional area of materials and peripheral force, shaft power of drum, power of motor, using point by point method to get the resultant strain of every drum and torsion of driving drum, calculating the maximum strain and the maximum reverse stopping torque, to give the support on theory for using belt conveyor with super-long distance, high angle under the coal mine.The specific designing ideas for structure of the parts are put forward, and start with driving equipment, hydromechatronics Controllable Starting Transmit (CST) is introduced, which not only can achieve flexible start-up of belt conveyor, but also can better guarantee the balance of motor power. There is a deep groove rollers with 4 carrier roller in the middle loading line of belt conveyor, this play an important role in enhancing the friction that the material give to the belt and advancing carriage dip. In the designing process of backstops, there are 2 backstops which required to complete the principle of the backstop independently are employed, in this case the capacity of security is advanced, in order to insure the belt conveyor with high angle runs safely.After using the super-long distance and high angle belt conveyor in the main inclined shaft of SHUANG LIU coal mine of FEN XI mining bureau, it shows that the theoretical calculation and structure design of belt conveyor with super-long distance, high angle and high strength are reasonable.
