Opis:
Pipe conveyors represent a continuous transport system that is difficult to obtain real operating data from in terms of operational characteristics’ research. That is why the research of these conveyors is mainly supported with the data from special, static testing rigs. However, the measurements do not provide corresponding operating results and can differ from actual operating conditions. That is why, a dynamic testing rig was designed for the research which also represents the smallest pipe conveyor worldwide. The article describes options of conveyor belts and pipe belt conveyor components examination with the use of static and dynamic testing rig, and researches a new design and implementation of a dynamic testing rig - the smallest fully functional pipe belt conveyor in the world with a length of 11 m and belt width of 0.6 m. The said testing device can provide data obtained during dynamic operation of the pipe conveyor, which compared with a static rig increases the accuracy and value of obtained data and results.

Opis:
Pipe conveyors make up important elements of ecological transport systems. They ensure the material is transported in the conveyor belt coiled to the shape of a pipe. Various stresses impact their most important component - the conveyor belt - straining it in both, the longitudinal and the transverse direction. This phenomenon arises in connection with the shape of the conveyor route of the pipe conveyor, the width and thickness of the conveyor belt, the volume of the material conveyed, and the like. In recent years, more and more authors have been researching contact dependencies of the normal forces acting on the idler rolls located in idler housings. Their task is to design such structure of a conveyor belt that will put the least strain on the idler rolls, thus significantly reducing the power required to ensure the movement of the pipe conveyor. In this way, greater efficiency of eco-friendly transport will be achieved. Following experimental research, the paper describes a regression model of dependencies of normal contact forces on tension forces required, as per individual idler rolls in idler housing.

Opis:
In order to release the lateral force of pipe conveyor belt in vertical transportation, the thesis had a study of the lateral force of the conveyor belt. By making use of Janssen Principles and fractal theory, based on reasonable simplification, the author established a mathematical model of the lateral force in vertical transportation, and with the research foundation of the pipe belt conveyor for underground transportation, through solution analysis, the author found out that the change of material diameter would lead to nonlinear variation of the lateral force of the conveyor belt. Under the circumstances of different material diameter, discrete element method was adopted to simulate the lateral force of the conveyor belt, thus working out the distribution curve chart of the lateral force. To verify the reliability of the theory, the author built an experimental platform for pipe conveyor belt in vertical transportation, and experimented with five groups of materials in different diameter, working out the strain of lateral force of the characteristic conveyor belt; by comparing the theoretical result, the simulation result and the experimental result, it showed that the solution to relieving lateral force through optimization selection of material diameter put forward in this thesis was reasonable and effective. It provides theoretical reference for the design of pipe belt conveyor.
