Abstract
The problems of researching the dynamics of the load-carrying body of a belt tubular conveyor (BTC) are formulated. It is noted that for BTC, at which the flat belt is rolled into a pipe with the help of special roller supports, the main danger is torsional vibrations. The factors causing torsional vibrations of the tubular belt are analyzed. An estimate of the maximum angle of rotation of the belt from the suddenly applied moment is given. A comparison of the angular turns of the tubular belt of the closed and open profiles is made. The relations of the main belt’s parameters, which exclude the possibility of its significant rotation and load spills are obtained.
Highlights
Tubular belt conveyors (BTC) have been increasingly used in various industries for moving long distances of bulk cargo.The advantages of this type of conveyors, compared with belt conveyors of traditional design, include the possibility of transporting fine and hazardous materials along complex curvilinear routes without transfer stations, excluding their spillage and dusting
We consider BTC, the tubular belt of which is formed by rolling the flat belt into the pipe, that is, the profile of the tubular belt of the conveyor has the form of a ring with a cut
Studies of the torsional vibrations of the BTC tubular belt showed that the torque applied suddenly to the cross section of the tape causes the section to rotate by an angle twice as large as in the case of static loading with the same moment
Summary
Tubular belt conveyors (BTC) have been increasingly used in various industries for moving long distances of bulk cargo. The advantages of this type of conveyors, compared with belt conveyors of traditional design, include the possibility of transporting fine and hazardous materials along complex curvilinear routes without transfer stations, excluding their spillage and dusting. The main disadvantage of BTC is the use of an special belt, the cost of which is commensurate with the cost of the entire conveyor. Belt tubular conveyors with the use of special belt are manufactured by Phoenix and Koch (Germany), Metco (Finland), Sicon (Sweden). Rather high capital costs for the manufacture of BTC are offset by low operating costs. The world operating experience of BTC showed that the cost of transporting a unit of load is significantly lower than that of other transport means
