When the tubular conveying belt deflects, the laser distance measuring sensors located at different angles can detect changes of measured values in real time when the connector protrudes, the deflection angle of the conveying belt can be determined through the changes of the measured values, and the deflection angle serves as a physical quantity to be converted into an electric signal to be transmitted into the deviation correcting system. The deviation rectifying system controls the power transmission assembly to enable the deviation rectifying carrier roller assembly to work, and then deviation rectifying of the tubular conveying belt is achieved. The device is high in structural creativity, convenient to operate and low in maintenance cost. And under the condition that the tubular conveying belt does not stop working, deviation rectification of the tubular conveying belt can be accurately and reliably achieved, and high practicability is achieved.

Description

Technical Field

[0001] The utility model relates to the technical field of tubular belt conveyors, and particularly relates to a deflection detection and rectification device for an adaptive tubular belt conveyor. Background Technique

[0002] In upstream and downstream transportation operations, the tubular belt conveyor often suffers from uneven pressure on the tubular belt due to uneven material weight, resulting in belt deflection and frequent situations where the conveyor belt deviates from the center line of the conveyor. This not only causes scattered materials along the line to affect the transportation efficiency, but also causes wear of the tubular conveyor belt and shortens its service life.

[0003] Traditional rectification methods usually involve shutting down the machine in advance and manual adjustment. At the same time, some rectification devices may cause too large a deflection angle between the tubular conveyor belt, leading to serious wear problems. A connecting rod rectification device for a tubular belt conveyor provided by the patent (application number: 201811568540.4) realizes the automatic rectification and torsion adjustment of the conveyor belt of the tubular belt conveyor by connecting two adjacent and axially symmetric adjustable idlers along the line. At the same time, the connecting rod mechanism realizes the adjustment of torsion under the linkage of both sides. However, there are obvious defects such as inability to real-time monitor the deflection angle, low rectification accuracy, complex structure, low efficiency, and even the need for manual adjustment of torsion.

[0004] Therefore, innovatively designing a device that can real-time detect the torsion angle of the tubular conveyor belt and perform immediate rectification has important practical application significance. Summary of the Utility Model
