Abstract

This paper reports a study into the holding capacity of tubular belt with partitions of a mixture of concrete and the effect of the technique of loading the tubular belt on increasing the pressure of the material on the partition. The task solved was the establishment of regularities in the process of transporting concrete with coarse aggregate and, on their basis, the determination of the structural and technological solution.

The studies have shown that the use of transverse partitions significantly increases the holding capacity of the load by a tubular belt and makes it possible to transport concrete with coarse filler.

It has been experimentally proved that when using the belt with transverse grooves Reef-1, the force of cargo on the partition is several times less than when using a smooth belt. The force of the load on the partition can be reduced if loading takes place on a horizontal or slightly inclined surface of the belt.

The properties of the load and the height of the layer of material loaded into the tubular belt significantly affect the force arising on the partition. With the height of the layer of material to be loaded, the force increases to a certain limit, which depends on the initial resistance to the shift of the material, after which it remains constant. Based on the results, plots of the dependence of the force on the partition on the angle of inclination of the belt and the weight of the material were constructed.

The operability based on specific initial (numerical) data of the derived theoretical dependences describing the efforts of the above-placed layers of material on the partition located in the tubular belt has been experimentally confirmed. The methodology of research and design of experimental benches for measuring the load on the partition of tubular belt conveyors was refined.

The results make it possible to consider the construction of a crane ‒ a concrete dispenser equipped with a tubular belt conveyor with partitions for the construction of high-rise structures
