Embodiment Construction
[0033] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.
[0034] figure 1 It is a schematic diagram of the steps of the tower crane slewing impact optimization method in an embodiment of the present invention, such as figure 1 shown. A method for optimizing the slewing impact of a tower crane, the optimization method comprising:
[0035] S01. Determine the slewing condition of the tower crane to be optimized;
[0036] When the slewing impact of the tower crane occurs, the most intuitive feeling comes from the tower crane operator and the vibration of the tower crane. However, the reason for these phenomena is that the torque change i...

The embodiment of the invention relates to the field of mechanical control, in particular to a tower crane rotation impact optimization method and device, control equipment and a tower crane, and the tower crane rotation impact optimization method comprises the following steps: determining a to-be-optimized rotation working condition of the tower crane; determining a torque impact factor of the rotation working condition, wherein the torque impact factor is used for evaluating the stability of the rotation working condition of the tower crane; and the deceleration slope time parameter in the rotation working condition being adjusted until the torque impact factor corresponding to the rotation working condition executed by adopting the adjusted deceleration slope time parameter is within a preset target interval. The invention further provides a corresponding device, control equipment and a tower crane. According to the implementation mode provided by the invention, the rotation impact of the tower crane in the rotation process can be monitored and reduced, and the user experience of an operator is improved.
Description
technical field [0001] The invention relates to the field of mechanical control, in particular to a tower crane slewing impact optimization method, a tower crane slewing impact optimization device, a tower crane control device and a tower crane. Background technique [0002] The operation process of the tower crane is mainly composed of several basic operations such as left and right rotation, internal and external luffing, lifting or landing, and the rotation operation accounts for a relatively high proportion of various operations in the operation process. The impact of stability phenomena such as pendulum on the subjective experience of operators on the tower cannot be ignored. The problem of "tooth beating" is a phenomenon that has attracted much attention from designers, customers and operators during the slewing process of tower cranes, and has a significant impact on the smooth operation of equipment. When the toothing occurs, the personnel on the tower will feel obv...
