Abstract.

Being loaded with lumps a conveyer belt experiences considerable impact load which can significantly shorten the belt life and disrupt the conveyer operation. Various devices are provided to weaken force of the lump impact on the belt. This article presents one of such devices which consists of two belt sections located parallel to each other under the upper run of the conveyer belt. Both sections are spring-loaded ensuring their tension as they become loose. So, this device presents a double-layer trampoline, which is located under the operating belt at areas of the belt loading. In order to choose the device parameters for different typical sizes of the protected belts and loading conditions it was necessary to develop a method for calculating deformation and design parameters for the receiving mechanism elements under impact load. Aim of this work was to create a mathematical model of collision process and to define forces and deformations of operating belt and elements of the receiving mechanism with taking into account initial parameters.

A central collision of a single lump against the moving belt is analyzed. Static and dynamic deflections, forces, dynamic-response factors, which an operating belt and both belt sections of receiving mechanism experience are defined with taking into account their geometry, rigidity parameters and impact energy. The obtained dependences allow to analyze operation of and to choose sustainable parameters for this construction.

Key words:

belt conveyer, receiving mechanism, impact load, dynamic-response factor, loading station, belt rigidity, impact force.
