Problems solved by technology

The hoisting system for port and wharf operations relies on the speed difference of the tires on both sides of the main body to correct the deviation. Considering the safety of the rigid body structure of the hoisting system, the speed difference of the tires on both sides cannot be changed at will, and it is difficult to use the existing control algorithm for deviation correction

Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one of ordinary skill in the art that the present invention may be practiced without these specific details. Therefore, the specific details set forth are merely exemplary, and specific details may be varied in the spirit and scope of the invention and still be considered to be within the spirit and scope of the invention.

[0042] The hoisting system in this embodiment can be used for port logistics. The hoisting system includes a crane, which includes but not limited to a tire crane, a straddle carrier, and a stacker. The hoisting system of the present invention will be described below using a tire crane as an example. The working principle of the automatic correction cont...

Abstract

The invention discloses an automatic deviation correction control method for a hoisting system, which comprises the following steps: obtaining the lateral displacement X and the advancing angle α generated by the deflection of the hoisting system; When it is also 0, it is judged whether the lateral displacement X and the advancing angle α satisfy the preset condition, and if the lateral displacement X and the advancing angle α do not meet the preset condition, then control the hoisting The system rectifies the deviation toward the center line, and if the lateral displacement X and the advancing angle α satisfy preset conditions, the hoisting system is controlled to reverse the deviation toward the center line. The automatic deviation correction control method of the hoisting system provided by the present invention can realize automatic deviation correction, thereby realizing the automatic deviation correction control of the hoisting system, and then effectively reducing the workload of the driver during operation.

Description

technical field [0001] The invention relates to the field of hoisting system transportation, in particular to an automatic deviation correction control method for the hoisting system. Background technique [0002] Port operations refer to the operation of ships entering and leaving the port for scheduling, loading and unloading cargo, and removing obstacles. Port operations are basically carried out with trailers, forklifts, cranes and other large mobile and fixed machinery and other hoisting systems as the main tools. Because the performance of the two frequency converters that drive the tires on both sides of the hoisting system cannot be exactly the same, coupled with the installation accuracy of large machinery and the flatness of the ground on the job site, it will easily lead to deviations in the process of advancing, which is inconsistent with the specified center route. Deviations in advance angle and lateral displacement are produced. Therefore, the deviation corr...
