Problems solved by technology

Electronic anti-sway technology is divided into two categories: open-loop control and closed-loop control. The open-loop control is simple in design and low in cost, but the control accuracy is slightly lower. The closed-loop control uses the feedback mechanism to adjust the control effect in real time to ensure better controllability. , but the implementation is complex and requires additional cost

Embodiment Construction

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0023] This application first proposes an anti-sway control method for an overhead crane, such as figure 1 As shown, the anti-sway control method for an overhead crane in this embodiment specifically includes steps S101 to S103:

[0024] Step S101: Calculate, acquire and send the swing frequency.

[0025] The swing calculation unit calculates, acquires and transmits the swing frequency.

[0026] Optionally, this embodiment further proposes a formula...

Abstract

The invention discloses a bridge crane anti-swing control method, a bridge crane device and a bridge crane, and relates to the technical field of motor control. The method comprises the following steps: calculating, obtaining and sending a swing frequency; correcting the acquired rotating speed preset signal based on the swing frequency to obtain a corrected rotating speed signal; and controlling the bridge crane based on the swing frequency and the corrected rotating speed signal. According to the bridge crane, the specific swinging frequency of the hoisting load can be effectively filtered out, interference between mechanical systems is effectively reduced, and hoisting load swinging generated by walking of a trolley mechanism of the bridge crane is restrained.

Description

technical field [0001] The present application relates to the technical field of motor control, in particular to an anti-sway control method of an overhead crane, an overhead crane device and an overhead crane. Background technique [0002] As an important loading equipment, bridge cranes have been widely used in modern production, such as port transportation, equipment manufacturing and other industries. During the crane operation, due to the influence of the acceleration and deceleration of the trolley and the unique oscillation characteristics of the mechanical system, the hoisting weight will sway back and forth, which not only seriously affects the improvement of the production efficiency, but may even lead to safety production accidents. Therefore, crane anti-sway technology has become a research topic in the past ten years. hot spot. [0003] Crane anti-sway and anti-sway have gone through two stages of mechanical anti-sway and electronic anti-sway. [0004] Mechani...
