Embodiment 1

[0047] Such as figure 1 and image 3 As shown, the tower crane structural deformation online monitoring system of the present invention includes a monitoring point module 1 arranged on the jacking frame of the tower crane, arranged under the tower crane and wirelessly connected with the monitoring point module 1 The three-dimensional ultrasonic scanning module 2 and the main console module 3 wirelessly connected and communicating with the three-dimensional ultrasonic scanning module 2, the monitoring point module 1 includes the first microprocessor module 1-1 and the monitoring point module 1 The first power supply module 1-2 powered by each electric module in the power supply module, and the first wireless communication module 1-3 and the ultrasonic drive circuit module 1-4 connected with the first microprocessor module 1-1, the The output terminal of the ultrasonic driving circuit module 1-4 is connected with an ultrasonic transmitting sensor module 1-5; the three-dimension...

Embodiment 2

[0058] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the number of the monitoring point module 1 is one. All the other structures and methods are the same as in Example 1.

[0059] During specific implementation, the main console module 3 can wirelessly receive the distance information and azimuth information of the designated monitoring point module 1 sent by the second microprocessor module 2-1 in real-time manually or automatically.

[0060] In summary, the three-dimensional ultrasonic scanning module 2 obtains the distance data between the monitoring point module 1 and the three-dimensional ultrasonic scanning module 2 on the jacking sleeve of the tower crane in a three-dimensional scanning manner, and according to the PTZ servo controller module 2-4 The rotated angle signal of the three-dimensional pan-tilt 2-9 fed back obtains the orientation information of the designated monitoring point module 1, and the main console modul...

Description

technical field [0001] The invention relates to the technical field of tower crane safety monitoring, in particular to an online monitoring system and method for structural deformation of tower cranes. Background technique [0002] Tower cranes (referred to as tower cranes) belong to a class of special mechanical equipment, mainly used for hoisting operations on construction sites. At present, my country has more than 300 tower crane manufacturers, with an annual output of nearly 20,000 tower cranes, of which small and medium-sized tower cranes below 80 tons account for more than 80%. [0003] The tower crane has a large working range and complex working conditions, and the large steel components that make up the tower crane are exposed to the external environment all the year round. Due to factors such as occasional impacts, sudden changes in climate, material aging, and foundation subsidence, these large steel components are prone to deformation, causing the tower crane t...
