[0019] The following is combined with Figures 1-5 The present invention will be further described below;

[0020] The existing rotating beam bridge includes a supporting pier 13, a rotating base 14 above the supporting pier, a supporting column 15 fixed to the top of the rotating base, and a rotating device 16 between the supporting pier and the rotating base. The upper and lower ends of the rotating device are fixedly connected to the rotating base 14 and the supporting pier 13, respectively. The supporting pier can provide stable support for the assembly of the beam bridge and the rotating operation. The rotating device includes existing structures such as a detection and leveling system, a positioning frame, a lower ball joint, an annular slide, a lower turntable, a traction reaction seat, a rotating pin, an upper ball joint, and a steel casing. Since the rotating device is existing technology, it will not be described in detail. The upper and lower parts of the rotating device are rotatably connected. When the upper part of the rotating device rotates, it can drive the rotating base to rotate, thereby realizing the rotating operation of the beam bridge. The beam bridge 17 is fixed to the top of the supporting column.

[0021] This utility model includes monitoring support rods 1 symmetrically arranged on both sides of the support column 15. The upper surface of the rotating base 14 is bolted with hinge blocks 2 at the positions corresponding to the two monitoring support rods. The lower surface of the beam bridge is also bolted with hinge blocks 2 at the positions corresponding to the two monitoring support rods. The upper ends of the two monitoring support rods are respectively connected to the two hinge blocks on the lower surface of the beam bridge by pins, and the lower ends of the two monitoring support rods are respectively connected to the two hinge blocks on the upper surface of the rotating base by pins. The two monitoring support rods are arranged at an angle.

[0022] Each of the two monitoring struts is equipped with a fixing mechanism between itself and the support column. The fixing mechanism includes a fixing connecting frame 3. The support column 15 has a fixing block 4 fixedly connected to its outer surface facing the two monitoring struts. The inner ends of the two fixing connecting frames 3 are respectively connected to the two fixing blocks 4 by bolts, and the outer ends of the two fixing connecting frames 3 are respectively connected to the two monitoring struts by bolts. Monitoring sensors 5 are adhered to the outer surfaces of both monitoring struts. The monitoring sensors are commercially available products and consist of a stress sensor, a data acquisition and processing unit, a wireless transmission module, a data analysis and early warning system, a power management system, and a protective shell. By setting up the monitoring sensors, the changes in different stresses on both sides during the rotation of the beam bridge can be monitored, and the monitoring information can be uploaded to an external data analysis center, which can effectively improve the stability and safety of the beam bridge rotation.

[0023] The fixing mechanism ensures that the monitoring struts and sensors are in a stable working state, increasing the stability of the device and facilitating stable monitoring of the rotation process by the sensors.

[0024] The monitoring struts provide good support for the use of monitoring sensors. At the same time, the monitoring struts can also transmit the unbalanced torque generated during the rotation of the beam bridge. When installing the monitoring struts, the installation angle of the monitoring struts can be adjusted according to the rotation requirements, so that the monitoring sensors can better detect the unbalanced torque during the rotation of the beam bridge.

[0025] Both ends of the monitoring strut are connected to the rotating base and the beam bridge via pins. After the beam bridge rotation is completed, the two hinge blocks can be removed with bolts for easy reuse of the device. The monitoring sensor can sense the stress changes generated by the monitoring strut and measure the unbalanced moment of the beam bridge based on the stress changes of the monitoring strut, so as to achieve the purpose of detecting the beam bridge attitude during the beam bridge rotation process.

[0026] It also includes an angle positioning mechanism, which includes a positioning collar 6. The positioning collar is fixedly installed on the top surface of the supporting pier 13. The outer end face of the positioning collar 6 is provided with a ring of evenly distributed scale lines 7. A ring of sliding grooves 8 is provided on the positioning collar below the scale lines. A positioning block 9 is slidably provided in the sliding groove. A fastening bolt 10 is threadedly connected to the positioning block.

[0027] The upper end of the connecting rod 11 is fixed on the rotating base 14, and the lower end of the connecting rod is equipped with a pressure sensor 12. The pressure sensor is placed in the groove 8 of the positioning collar, and there is a distance between the pressure sensor and the positioning collar, that is, the pressure sensor does not contact the positioning collar.

[0028] Workers can select the corresponding scale position according to the required rotation angle of the beam bridge, and then fix the positioning block in that position. This allows for monitoring of the rotation angle during the rotation process, preventing the rotation angle from being too large or too small, which could affect the construction of the beam bridge.

[0029] Once the positioning block has moved to the appropriate scale position, tighten the fastening bolts to make them fit tightly against the positioning collar, which facilitates fixing the positioning block and ensures that it remains stable at the corresponding scale position.

[0030] When the bridge beam rotates, the connecting rod drives the pressure sensor to move inside the sliding groove. The pressure sensor does not contact the positioning collar. When the pressure sensor rotates to the point of contact with the positioning block, it senses the pressure and sends a stop signal to the rotation device, causing it to stop rotating. This facilitates control of the bridge beam's rotation angle and effectively improves the sensitivity of the bridge beam's rotation, preventing excessively small or large rotation angles from affecting the bridge's construction. Both the pressure sensor and the monitoring sensor wirelessly transmit monitoring information.

[0031] Working principle: When monitoring the bridge rotation process, the hinge blocks at both ends of the monitoring strut are first fixed to the top surface of the rotating base and the bottom surface of the bridge using bolts. Then, the fixed connection frame is installed using bolts. Next, a suitable scale position is selected based on the required rotation angle of the bridge, and the positioning block is slid to that position. The bolts are then tightened to ensure the positioning block remains stable in that position. The rotating device is then activated to rotate the bridge. When the bridge rotates to a specific angle, the pressure sensor contacts the positioning block and sends a stop signal to the rotating device, thus completing the bridge rotation. Throughout the entire bridge rotation process, the monitoring sensor can monitor different stress changes on both sides of the bridge and deduce the unbalanced torque of the bridge during rotation based on the stress value changes. This allows for real-time monitoring of the bridge's posture during rotation, ensuring the smooth progress of the rotation construction and the safety of the bridge structure.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
