| Continuous conveyor can be widely applied to various materials of the pipe belt conveyor, conveying material surrounded by conveying belt in the round, it is not affected by wind, rain and other external environment, avoid the material fall, dust and pollution of the environment, but also to avoid the pollution on the external environment of the material. Laiwu Steel has4pipe belt conveyor, are put into use in2004-2006, diameter is300mm, head and tail plane straight line distance of3.7km,3.0km,1.7km,1.5km respectively, which are three coke conveyor, a sintering mixing conveyor.Conveyor belt conveyor belt rotation, torsion phenomenon may occur in the operation process of the circular tube, the conveyor belt lapping position from above, deflection to the sides or bottom, causing the conveyor belt and roller abnormal wear, material falling, even the belt turning, make equipment fault is larger, its economy the loss of hundreds of thousands of millions of small, large, Laiwu Steel1.7km pipe belt conveyor in early2012, both for belt conveyor, conveyor belt caused a series of problems torn edges, conveyor belt, conveyor belt, turn head tail flip, the eventual replacement of the entire conveyor belt, consumption of about5000000yuan of funds.Therefore, in this paper, the forming force of belt conveyor in running gravity, bending resistance, wedge resistance and pressure calculation and analysis of resistance of tube, get all kinds of resistance to the effects of the conveyor belt and the roller group, and cause the conveyer belt torsion. As in does not affect the normal operation of circular pipe belt conveyor, create a roller can realize with the conveying belt torsion and rotation, and through the installation of certain measurement of rotation angle, to realize the pipe belt conveyor middle section reverse fault detection of circle. And through the principle of roller pitch adjustment method, manufactured by rotary encoder and only correcting device for electric push rod control, so that it can be realized according to the conveyor belt torsion angle to automatically on the conveyor belt conveyor belt deviation, when the reverse adjustment to set the allowable range, the device can recover to normal position, does not affect the normal operation of belt conveyor. |
