The turning system consists of a lower rotary table, an upper rotary table, a spherical hinge, a slideway and a traction system, and the turning process is realized by pulling a traction rope by a continuous jack to form a rotating couple.
The rotation method is adopted for construction, the rotation quantity is large, the self weight is large, the time window is short, the construction difficulty is large, the bridge type is complex, and how to accurately position and stably rotate the rotation bridge is a main difficulty in rotation. Therefore, various data records in the rotating process play an important role in optimizing and supplementing the rotating bridge system, and the data records are data storage of later rotating construction and are also the basis for revising the technical standard of the rotating bridge.
The existing monitoring method in the bridge turning construction process mainly adopts a measuring robot to measure and then carries out manual calculation, and has the advantages of low automation degree of turning construction monitoring, long coordination period among construction steps and low visualization degree.
The swivel monitoring system is an instrument capable of automatically monitoring a swivel bridge in a swivel process, and can monitor and visualize parameters such as a swivel bridge rotating distance, a rotating angle, an angular velocity, a linear velocity and a lower turntable control section stress. The situation that the existing swivel construction is low in automation degree and long in coordination period among construction steps can be changed, and meanwhile, unsafe states caused by human errors and insufficient monitoring frequency can be avoided. Therefore, how to realize the rotation control, monitoring and visual integrated full-automatic monitoring is an urgent problem in the field of rotation construction at present.
