Description

TECHNICAL FIELD

[0001] The utility model relates to tower crane monitoring system technical field, concretely is a tower crane intelligent safety monitoring system. BACKGROUND

[0002] With the development of the construction industry, the construction scale is expanding, and high-rise, super high-rise building projects are increasing. As an important hoisting equipment in construction, the safety and stability of the tower crane are directly related to the safety of the entire construction site. However, due to the complexity of the operation of the tower crane and the variability of the site environment, the safety problem of the tower crane is increasingly prominent. There are many risks in the operation of the tower crane, such as overload, tilting, collision, etc., which can cause serious accidents.

[0003] In order to ensure the normal operation of the tower crane, a monitoring and management system needs to be installed in the tower crane. The existing tower crane monitoring system collects information through various sensors installed on the tower crane to monitor the operating state of the tower crane, but it cannot provide real-time and comprehensive feedback on the actual state of the tower crane, which poses a significant safety hazard. The existing tower crane monitoring system mainly uses an electronic level to collect the inclination of the tower body to realize the anti-tipping monitoring of the tower crane. However, due to the large size of the tower crane structure, the harsh working environment, and the large amount of work load, the connecting bolts are prone to looseness, the weld structure is weakened, and the foundation is prone to uneven settlement, which can damage the integrity of the tower crane steel structure. The electronic level cannot detect the integrity of the tower crane steel structure, which can cause safety hazards.

[0004] In addition, there is a line-of-sight blind area during the operation of the tower crane, which can cause the operator to fail to timely detect potential dangers within the operating range of the tower crane, thereby causing safety accidents. Moreover, the tower crane control room is at a high altitude from the ground, and the lower part of the tower arm, especially the lower part of the hook, cannot be effectively observed. Therefore, when lifting objects, the operation can only be guided by the ground command personnel, which is time-consuming and labor-intensive, and the work efficiency is low. Sometimes, serious safety accidents can occur due to inadequate command. During the jacking operation of the tower crane, the driver cannot observe the running state below, which can cause operational errors and safety accidents. In addition, the operation behavior of the tower crane driver and the arrangement of the tower crane drum wire rope can affect the safety of the tower crane. The existing monitoring system only visualizes part of it, and cannot fully grasp all the dynamics without dead angles. UTILITY MODEL CONTENTS
