Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in this application can also be realized.

[0021] The first embodiment of the present invention relates to an automatic deviation correction method for a tire crane walking in a straight line. The walking direction of the tire crane is automatically judged by the gyrocompass. If there is a deviation between the walking direction of the tire crane and the original direction, the devia...

Abstract

The invention relates to the field of harbor machinery, discloses an automatic deviation correcting method and system for linear travelling of a RTG (Rubber-Tyred Gantry crane). The automatic deviation correcting method for linear travelling of the RTG comprises the following steps: during the travelling process of the RTG, periodically detecting the travelling direction of the RTG with a gyrocompass mounted on the RTG, and detecting a travelling deviation of the RTG according to the deviation direction of the RTG to obtain a deviation angle; and if the deviation angle is not zero, generating a control signal according to the deviation angle and sending the control signal to an actuator of a driving wheel of the RTG. The invention further discloses the automatic deviation correcting system for linear travelling of the RTG, which comprises the gyrocompass and a controller. Through the automatic deviation correcting method for linear travelling of the RTG, the RTG is enabled to realize automatic deviation correction, so that the labor intensity of RTG workers is relieved, and the accident occurrence probability is effectively reduced.

Description

technical field [0001] The invention relates to the field of port machinery, in particular to an automatic deviation correction method and system for a tire crane traveling in a straight line. Background technique [0002] Container gantry crane is a machine specially used for stacking and loading and unloading operations in container yards. There are two types: tire-type container gantry crane and rail-type container gantry crane. The rubber-tyred container gantry crane is also called the rubber-tyred gantry crane (RTG), and the rail-mounted container gantry crane is also called the rail-mounted gantry crane (RMG). However, rail cranes need to lay tracks, resulting in poor mobility, inability to transfer across regions, high infrastructure investment costs, and limited power supply. On the contrary, the tire crane has the advantages of effective use of the yard, low basic investment, high mobility, simple operation, and hybrid power supply, making it easy to promote. [0...
