Technical Field

[0001] The utility model relates to the technical field of tower crane lifting balance, in particular to a tower crane lifting balance monitoring and adjusting device. Background Art

[0002] In order to adapt to the heights of different floors, the height of the tower crane is constantly increasing as the number of floors in high-rise buildings continues to increase. During the jacking process of the tower crane, it is necessary to ensure that all components in the jacking system are complete and in place to ensure the normal jacking.

[0003] Application No. CN202021627259.6 discloses a real-time monitoring balance adjustment device for tower crane lifting. The device includes a dual-axis inclination sensor for obtaining the verticality signal of the outer climbing frame during the lifting process. The outer climbing frame is provided with an upper adjustable wheel group and a lower adjustable wheel group. The upper adjustable wheel group and the lower adjustable wheel group respectively include a plurality of roller seats, rollers and a balance adjustment cylinder. The dual-axis inclination sensor is connected to the main controller, which is used to receive the verticality signal and set the verticality threshold of the outer climbing frame. When the verticality signal exceeds the verticality threshold, the main controller controls the balance adjustment cylinder to adjust the outer climbing frame to within the verticality threshold range. The upper adjustable wheel group and the lower adjustable wheel group of the utility model can be adjusted according to the real-time feedback on the site, and are automatically controlled by a programmable controller and a hydraulic system, which effectively solves the verticality and balance problems during the tower crane lifting process. The device has a simple structure and is universal. It can be used for different tower crane models, which improves the safety of the tower crane during the lifting process. When the application detects balance, the detection is not sensitive, which increases the risk of tower crane use. Utility Model Content
