Problems solved by technology

[0005] The above-mentioned automatic deviation correction systems are all based on mechanical deflection measurement, which requires high installation accuracy, so they have the defects of complicated installation and high cost, and are greatly affected by mechanical wear and aging, thereby reducing the service life
Moreover, for the encoder method, since the deflection is indirectly measured by measuring the rotational speed and stroke, there is a cumulative error, which reduces the measurement accuracy

Abstract

The invention provides an automatic deviation-control system and a method for a gantry crane based on a beidou satellite positioning system. The automatic deviation-control system is used in the gantry crane. The automatic deviation-control system comprises a processor, a controller, a beidou satellite signal receiving plate and at least two beidou satellite antennae, wherein all beidou satellite antennae are fixedly installed on a main beam of the gantry crane, signal output ends of all beidou satellite antennae are connected with signal input ends of the beidou satellite signal receiving plate, signal output ends of the beidou satellite signal receiving plate are connected with signal input ends of the processor, and signal output ends of the processor are connected with signal input ends of the controller. The system cannot be affected facts such as mechanical part abrasion and ageing. Therefore, the system has the advantages that the service life is long, no accumulated error exists and measurement accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of gantry crane control, and in particular relates to an automatic deviation correction system and method for a gantry crane based on the Beidou satellite positioning system. Background technique [0002] Gantry cranes, especially long-span rail-mounted gantry cranes, are widely used in shipyards, docks, steel mills and other industrial sites, with a maximum load of 1,600 tons and a maximum span of more than 200 meters. Common gantry crane structure usually consists of traveling wheel set, gantry frame, lifting trolley, spreader, power system and control system and other parts. Among them, the gantry frame is the bearing mechanism of the entire gantry crane and the basis for the installation of other components. The gantry is composed of a main beam arranged horizontally and rigid outriggers and flexible outriggers respectively installed at both ends of the main beam; traveling wheel sets are respectively i...
