Problems solved by technology

The standard design method is formed by years of experience in the design and use of short-distance conveyors. In the past, there were few studies on the dynamic problems of conveyors, which failed to reveal the essential problems in the process of conveyor movement. For long-distance conveyors Distance, high-speed conveyor design, some problems that have little influence on ordinary belt conveyors are highlighted
For example, the investment cost of the conveyor belt is too high, the calculation of the running resistance of the conveyor is inaccurate, the power of the drive motor of the selected conveyor is too large, and the designed tensioning device cannot be used normally, etc.

Embodiment Construction

[0319] The calculation process of the inventive method is carried out with the following steps:

[0320] 2.1 Unit number

[0321] Numbering principle:

[0322] The head roller is the last unit, and each conveyor belt section is two adjacent rollers. The number of units in this section is Num(i), and the number of sections is the same as the number of rollers, that is, NPul sections;

[0323] The roller is one degree of freedom; the tensioning device (automatic or heavy hammer) is two degrees of freedom;

[0324] Total units: Nelement = Σ i = 1 NPul Num ( i ) + NPul + Ntake - - - ( 2 - 1 )

[0325] NPul - the number of rollers;

[0326] NTake - tension num...

Abstract

Belonging to technical area of mechanism design, the method includes two portions: establishing kinetic equation of belt conveyor, and resolver for kinetic equation. Kinetic equation of conveyor system is obtained from combination of kinetic equations of conveyor belt, driving unit, and tension unit. The resolver for kinetic equation is obtained from calculations for following factors: running resistance of dynamic procedure, total length of conveyor belt, parameter of each roller, mass of cylinder, stiffness matrix, start-up procedure and stopping procedure etc. Being clear and accurate concept of kinetic equation, the invention gives out boundary condition and initial condition of kinetic equation for continuous model. The invention is closer to practical situation of running resistance to raise accuracy for solving data. Thus, the invention discloses scientific foundation for designing belt conveyor.

Description

technical field [0001] The invention belongs to the technical field of mechanical design, in particular to a method for calculating dynamic design parameters of a belt conveyor. Background technique [0002] Existing belt conveyors are usually designed using standard calculation methods. For example, German DIN22101, international standard ISO5048, American Conveyor Manufacturers Association CEMA standard, and Goodyear, and Goodrich calculation methods. In the past, my country usually used the TD75 calculation method (this method basically followed the calculation method of the former Soviet Union) or the international standard ISO5048 calculation method. The DTII Fixed Belt Conveyor Design and Selection Manual released in 1994 used the international standard calculation method. . [0003] Practice has proved that the ordinary belt conveyor designed by these standard calculation methods has achieved good results. The standard design method is formed by years of experience ...
