Abstract: The article discusses the existing types of conveyor belt catchers. The catchers are divided into categories based on their method of impact on the conveyor belt in the event of a breakage. The article also examines the disadvantages of these catchers from the perspective of their safe use in transporting people using conveyor belts. The article concludes that there is currently no effective design solution for a conveyor belt catcher that ensures its safe use. The features of the design of the belt conveyor's catcher device used on the cargo-people break-off conveyor have been established, taking into account modern safety requirements. The knife-type executive body of the belt conveyor's catcher device, which is a sharpened bar shaped like a trough, has been chosen as the optimal design. A finite element modeling of a single actuator of a belt conveyor catching device was carried out to determine the behavior of the catcher actuator design with different directions and angles of sharpening. The following options for sharpening the actuator scraper are considered: sharpening the actuator scraper from the side of the broken belt movement; sharpening the actuator scraper from the side opposite to the broken belt movement; double-sided sharpening of the actuator scraper (with the same angle on each side). As a result of computer modeling, the maximum displacement of the individual actuator's structural elements was determined, depending on the angle of sharpening of the scraper of the belt conveyor's catcher actuator, and the resulting reactive moment relative to the catcher supports. Computer modeling of models of elements of the scraper of the executive body with different options and angles of sharpening and determined the forces at which the edge of the sharpened scraper is irreversibly deformed at the point of contact with the conveyor belt. It is established that the option of sharpening the scraper of the executive body does not have a significant effect on its strength.
