It includes basic theories and research, planning, survey and design, construction, maintenance and repair of bridges. In the prior art, at present, the rotation speed control and process monitoring of the rotating bridge mainly rely on manual monitoring and simple sensor systems. However, the traditional rotation speed control mainly relies on manual experience and simple measuring instruments, and has problems such as low control accuracy and difficulty in dynamic adjustment according to real-time working conditions. At the same time, the structural status monitoring during the rotation process is mostly decentralized and local, lacking comprehensive and systematic intelligent monitoring means, and unable to timely and accurately discover potential safety hazards and construction deviations. For this reason, the present invention proposes a rotation speed control and process intelligent monitoring device and a monitoring method for a rotating bridge to solve the above problems. Summary of the invention

[0026] The support column 7 provides stable support for the total station 1, thereby facilitating the monitoring of the total station 1. Through the lateral movement of the transverse plate 4, the insertion rod 5 is driven to be inserted into the insertion hole provided on the fixing seat 6, thereby fixing the transverse plate 4, and then fixing the T-shaped seat 2, and finally fixing the total station 1. When the transverse plate 4 moves in the opposite direction, the limit between the insertion rod 5 and the fixing seat 6 is released, thereby facilitating the disassembly of the total station 1. The data integration center 14 is set up to facilitate global control. Through the integration and adjustment of the data center, the signal transceiver 15 receives and sends signals, so that the traction device 13 drives the drive ring 12 to rotate, and the drive ring 12 drives the beam body 10 to rotate, so that the beam body 10 rotates stably with the cooperation of the ball joint 11, and then drives the bridge body 8 to rotate, so as to realize the precise control of the rotation speed and the comprehensive, real-time and intelligent monitoring of the rotation process, and improve the safety, reliability and construction efficiency of the rotating bridge construction.

[0027] Embodiment 2: On the basis of embodiment 1, the lower surface of the T-shaped seat 2 is fixedly connected to one side of the connecting seat 16, and the other side of the connecting seat 16 is fixedly connected to the non-output end of the electric cylinder 17. The connecting seat 16 is fixedly connected between the T-shaped seat 2 and the electric cylinder 17, and the output end of the electric cylinder 17 is fixedly connected to the mobile frame 18. The mobile frame 18 is rotatably connected to one end of the lower connecting rod 19 through a pin shaft, and the other end of the lower connecting rod 19 is rotatably connected to the transverse plate 4 through a pin shaft. The top of the transverse plate 4 is rotatably connected to one end of the L-shaped frame 20 through a pin shaft, and the other end of the L-shaped frame 20 is rotatably connected to one end of the upper connecting rod 21 through a pin shaft, and the other end of the upper connecting rod 21 is rotatably connected to the connecting seat 16 through a pin shaft, and the middle part of the L-shaped frame 20 is rotatably connected to the mobile frame 18 through a pin shaft, the total station 1 is electrically connected to the signal transceiver 15, and the signal transceiver 15 is electrically connected to the data integration center 14.

[0028] When the total station 1 needs to be installed, its bottom is placed in the fixed seat 6. A socket is provided on the outer ring surface of the fixed seat 6. The socket is slidably connected to the plug rod 5. The output end of the electric cylinder 17 is controlled to extend, thereby driving the movable frame 18 to move downward. The movable frame 18 drives the lower connecting rod 19 and the L-shaped frame 20 to move under the connection of the pin shaft. The lower connecting rod 19 drives the transverse plate 4 to move. The L-shaped frame 20 cooperates with the rotation of the upper connecting rod 21 through the pin shaft, thereby limiting the transverse plate 4, and then realizing the movement of the transverse plate 4 in the direction close to the socket until the transverse plate 4 abuts against the inner ring surface of the fixed seat 6, thereby fixing the T-shaped seat 2, and then fixing the total station 1, which is convenient for monitoring the total station 1. When the total station 1 needs to be disassembled, it can be done by driving the electric cylinder 17 to retract.

[0029] Embodiment 3: On the basis of embodiment 2, the bottom of the bridge body 8 is fixedly connected to the beam body 10, strain sensors 24 are installed on the beam body 10 and the ball joint 11, the strain sensor 24 is electrically connected to the signal transceiver 15, the data integration center 14 is electrically connected to the traction device 13, and the driving ring 12 is driven by the traction device 13 to realize the rotation of the beam body 10, and the outer ring surface of the bottom of the ball joint 11 is provided with an annular rail 22, the annular rail 22 is slidably connected to the sliding column 23, and the top of the sliding column 23 is fixedly connected to the driving ring 12, and the sliding connection between the annular rail 22 and the sliding column 23 is made more stable during the rotation of the bridge body 8 driven by the beam body 10.

[0030] A high-precision total station 1 is used to monitor the spatial posture of the rotating bridge body 8, including the rotation angle, elevation, lateral and longitudinal offsets, in real time. By comparing with the designed rotation posture data, the posture deviation during the rotation process is discovered in time, and corresponding corrective measures are taken to ensure that the rotating bridge body 8 can accurately rotate to the designed position. Strain sensors 24 are buried in the main load-bearing components of the rotating bridge, such as the beam body 10 and the ball joint 11, to form a strain monitoring network to monitor the stress and strain changes of the structure during the rotation process in real time. By analyzing these data, it can be determined whether the structure is in a safe stress state, and possible structural damage or local stress concentration problems can be discovered in time. The above-mentioned various monitoring data are integrated into a complete set of monitoring data. The system uses data analysis and artificial intelligence algorithms to establish a safety assessment model for the construction process of the rotating bridge. When the monitoring data shows abnormal changes or the safety assessment model predicts potential safety risks, the system automatically issues an early warning message to remind construction personnel to take timely measures to deal with the situation. When the calculated actual rotation speed deviates from the preset speed, the control system automatically adjusts the traction device 13, such as the working parameters of the jack, such as oil pressure and stroke, according to the size and direction of the deviation, to achieve precise control of the rotation speed. For example, if the actual speed is too fast, the system will reduce the traction force of the traction device 13; if the speed is too slow, the traction force will be appropriately increased to keep the rotation speed within the preset reasonable range.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
