Problems solved by technology

In the application process of tower cranes, there may be problems of operation safety and fault maintenance. Once the tower crane fails, it will have a certain impact on the construction progress, and may lead to increased construction risks, which seriously threaten people's lives and property safety.
Due to the particularity of tower crane work, on the one hand, its operating state and load are constantly changing during the working process, which will continuously cause impa

Abstract

The invention relates to a tower crane rotation process state control method. According to the method, a pose sensing device is adopted to obtain pose change data of the top end of a tower crane in the rotation process of the tower crane, and when the pose change exceeds a set safety threshold range, a system can give an alarm for reminding, and meanwhile, an intelligent control strategy is automatically started to obtain the vibration direction of the tower crane; and a reverse driving force opposite to the vibration direction of the tower crane can be applied by the system to the tower crane by controlling an electrical system of the tower crane and modifying relevant parameters of a frequency converter for controlling rotation actions, so that the vibration direction of the tower crane is opposite to the acceleration direction of the tower crane along an X axis or a Y axis, the vibration condition of the top end of the tower crane is inhibited, and stable operation of the tower crane is ensured.

Description

Technical field [0001] The present invention relates to the field of tower crane construction monitoring and control technology, and more particularly to a state control method for a tower rotary process. Background technique [0002] In the process of continuous improvement in my country's socialization, the application of tower cranes is also common. In the processing of the tower crane, there may be operational safety and fault repair issues. Once the tower crane will have a certain impact on the construction progress, and may result in an increase in construction risk, seriously threaten people's life and property safety. Since the tower machine has its own specialty, on the one hand, its operating state and load changes in the process, thereby constantly impacts the various components of the crane, which has adversely affects the service life of the tower machine. On the other hand, the tower machine is vibrated by the tower machine caused by different factors such as the li...
