Abstract

The invention relates to a tower crane ascending and descending section safety system. The system comprises a main control unit and a hydraulic oil cylinder control unit connected with each other, a first acceleration sensor, a wind speed sensor, a dip angle measuring device, a first driver card reader, a first display screen and a strong current control unit connected with the main control unit, and a second acceleration sensor, a second driver card reader, a second display screen and a height sensor connected with the hydraulic oil cylinder control unit. The system is safe and feasible, can comprehensively realize the safety monitoring management of tower crane ascending and descending sections, and reduces the accident rate in the phase.

Description

technical field [0001] The invention relates to a safety system for raising and lowering joints of a tower crane, which belongs to the technical field of construction machinery safety. Background technique [0002] As high-rise buildings are becoming more and more common in urban construction, tower cranes, as the main construction machinery on the construction site, are responsible for the main transportation tasks, and their high lifting height and wide coverage can greatly shorten the construction period. It is widely used in construction sites due to its convenient disassembly and other characteristics. However, while it brings great convenience to construction, it also has a negative impact on safety production due to its high-altitude operation, and has become one of the main hidden dangers of safety accidents at construction sites. [0003] Among many tower crane safety accidents, the probability of occurrence during the installation and disassembly process has reach...
