Description

Technical Field

[0001] The present invention relates to the technical field of cranes, and in particular to an automatic guiding device and method for the arc-shaped track operation of a crane trolley. Background Art

[0002] A crane is a multi-action lifting machinery that uses a hook or other picking device to hang heavy objects, vertically lift and horizontally move heavy objects within a certain range. It is also called a crane and belongs to material handling machinery.

[0003] The angle of the automatic guide device for the arc track of the crane trolley cannot usually be adjusted at will. The reason is that the shape and curvature of the arc track itself are fixed, and the design of the guide device is based on the specific track shape and curvature. If the angle is adjusted at will, it may cause problems in the coordination between the guide device and the track, such as poor contact between the roller and the track, jamming, etc., which will affect the normal operation of the crane. To this end, an automatic guide device and method for the arc track of the crane trolley are provided. Summary of the invention
