Раціоналізація роботи перевантажувальних кранів на контейнерних терміналах вантажних станцій

Abstract

The article considers the issue of efficiency of technical equipment of container terminals and rationalization of handling facilities and economic justification of their required number for the estimated service life, taking into account the allocation of investments in conditions of limited resources. One of the main problems of optimal control of reloading processes is the choice of a rational strategy for controlling loading and unloading machines within the work cycle, when the range of their movement at design speeds and accelerations is crucial given the constraints imposed on control parameters determined by design and operational conditions (permissible speeds and accelerations for a particular cargo front, maximum traction, operational productivity, site capacity, etc.). The optimization criteria can be the cost parameters for performing the basic operations of the operating cycle, taking into account energy costs depending on the range of loading and unloading machines. In the case where the container site is serviced by several handling equipment, the downtime of one group of cars depends on the downtime of other handling facilities. At existing freight stations, the length of container sites ranges from 100 to 300 m and more. The intensity of use of the length of the cargo front is very small, which causes a large amount of shunting work, interoperable downtime of loading and unloading machines and rolling stock. Thus, the introduction of rational control technology for loading and unloading facilities should be consistent with the design of the cargo station and container terminal, which would allow to fully implement all the design parameters with the lowest operating costs.
