Description

Technical Field

[0002] At present, tower cranes are one of the indispensable and important equipment in construction, and are widely used in high-rise buildings, bridge construction and other fields. As the height of construction projects continues to increase, it is particularly important to ensure the safe operation of tower cranes. Especially for tall tower cranes, the verticality directly affects the stability and safety of the entire system. Therefore, real-time monitoring of the verticality of tower cranes is of great significance, which can effectively prevent various safety accidents caused by tilt.

[0003] In order to effectively monitor the verticality of tower cranes, existing technical solutions usually use plumb line method and theodolite method to monitor the verticality of tower cranes. However, the above existing technologies have some shortcomings in practical application; the plumb line method is easily affected by external environmental factors such as wind and temperature changes, resulting in inaccurate measurement results. When working at high altitudes, hanging the plumb line and keeping it stable requires a lot of manpower and time. The operation process is cumbersome and there are certain safety hazards; the theodolite method requires sufficient space around the tower crane to set up the instrument, and requires the measurement site to be open and without obstructions. It is difficult to find a suitable measurement position when the construction site is small or there are obstacles such as buildings around it; the traditional monitoring device may cause distortion of monitoring data due to the lack of effective protective measures, and thus cannot accurately reflect the actual vertical state of the tower crane. And it is affected by changes in the installation position or environmental conditions, which reduces the reliability and efficiency of tower crane verticality monitoring.
