Design of Double Oil Cylinder Hydraulic Tensioning Device for Belt Conveyor
[Purposes]The hydraulic tensioning device is a key component of the retractable belt con-veyor,which is of key significance to ensure the stable operation of the conveyor in the process of start-ing,driving and braking,but the design of the traditional hydraulic tensioning device has the shortcom-ings of inconvenient tension adjustment and complex structure of the tensioning device.Therefore it is necessary to conduct research on this matter.[Methods]A double-cylinder hydraulic tensioning device suitable for belt conveyor was designed,which had the advantages of both screw tensioning device and hydraulic tensioning device.[Findings]The device had the advantages of stable working state,rapid re-sponse speed,small space requirement and outstanding performance,and the double-cylinder design could also greatly reduce the probability of deviation of the conveyor belt.[Conclusions]This device is mainly used on short distance conveyors,which not only extends the service life of belt conveyors,but also greatly improves the safety factor of work.
