METHOD AND DEVICE FOR MEASURING LIFTING MOMENT OF TOWER CRANE AND MONITORING SYSTEM

摘要

Disclosed are a method and a device for measuring a lifting moment of a tower crane and a lifting moment monitoring system, in which the method includes: detecting a flexure displacement of an arched plate (20), the arched plate (20) being fixed in a main chord rod (10) of the tower crane; and calculating the lifting moment corresponding to the flexure displacement by means of a pre-established Neural Network model and the flexure displacement of the arched plate (20). By way of the above technical solution, the measuring of the lifting moment can be achieved by utilizing the arched plate (20) and a displacement sensor (30), thereby achieving the monitoring and controlling of the moment without adopting a device that is relatively high in price and involves complex installation for measuring the gravity and magnitude, thus it is small in volume, simple in structure, and low in cost and maintenance expenses, with a wide application range for tower cranes of various tonnages.
