Description

Technical Field

[0001] The present invention relates to the technical field of hoisting engineering monitoring, in particular to a roadbed box relative deformation monitoring system. Background Art

[0002] When large-scale lifting machinery is performing lifting operations, multiple steel roadbed boxes are usually laid under the ground structure of the lifting machinery to reduce the ground pressure by increasing the ground area to meet the bearing capacity requirements of the foundation. The factor that has the greatest impact on safety during the lifting operation is the differential settlement of the foundation. Therefore, mastering the relative deformation between the roadbed boxes under the lifting machinery plays a key role in controlling the safety of the lifting project. At present, the monitoring of the roadbed boxes during the lifting operation is mainly done by manual settlement observation using a level. This method measures multiple points at a time and requires multiple observations at different sites. It is time-consuming and requires a large amount of data calculation. It is also prone to errors and cannot grasp the real-time safety status of the lifting machinery in time, which affects the judgment of the lifting safety. Therefore, there is an urgent need for a deformation monitoring system that can automatically observe the relative deformation between the roadbed boxes under large-scale lifting machinery, can observe in real time, dynamically reflect the stability of the roadbed boxes, and can be flexibly installed and reused. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art and to provide a deformation monitoring system that can automatically observe the relative deformation between the roadbed boxes under large lifting machinery, and can observe in real time, dynamically reflect the stability of the roadbed boxes, and can be flexibly installed and reused.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] A roadbed box relative deformation monitoring system includes a connecting base plate, a photosensitive panel and a laser module. The connecting base plate is fixedly arranged in the middle of the side end of the roadbed box, and each roadbed box is provided with a connecting base plate on the same side; the photosensitive panel and the laser module are respectively arranged on both sides of the connecting base plate, and the photosensitive panel on each connecting base plate faces the opposite direction of the laser irradiation of the laser module. Each photosensitive panel is used to receive the laser beam excited by the laser module on the previous roadbed box, and the laser of each laser module irradiates the photosensitive panel on the next roadbed box. The photosensitive panels are each provided with photosensitive receivers arranged in a matrix.

[0006] Furthermore, vertically distributed mounting holes are provided on the sides of the connecting base plate.

[0007] Furthermore, the laser module is a red laser.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] This invention utilizes a photosensitive panel and laser module for automatic monitoring. Combined with wireless communication equipment, it can automatically collect and transmit data, avoiding data errors caused by recording, transmission, and calculation errors during leveling measurements and enabling timely data acquisition. By monitoring differential settlement and posture, the real-time position of the roadbed box is fully understood, providing strong support for determining the safety of lifting machinery. The connecting base plate, photosensitive panel, and laser module can be combined into a single unit and installed on the side of the roadbed box, making it easy to install, disassemble, and reuse. This is more economical than requiring multiple people to perform leveling measurements. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0016] like Figures 1 to 3 As shown, a roadbed box relative deformation monitoring system includes a connecting base plate 1, a photosensitive panel 2 and a laser module 3. The connecting base plate 1 is fixedly arranged at the middle part of the side end of the roadbed box 4, and each roadbed box 4 is provided with a connecting base plate 1 on the same side; the photosensitive panel 2 and the laser module 3 are respectively arranged on both sides of the connecting base plate 1, and the photosensitive panel 2 on each connecting base plate 1 faces in the opposite direction of the laser irradiation of the laser module 3. Each photosensitive panel 2 is used to receive the laser beam excited by the laser module 3 on the previous roadbed box 4, and the laser of each laser module 3 irradiates the photosensitive panel 2 on the next roadbed box 4. The photosensitive panels 2 are arranged with photosensitive receivers arranged in a matrix.

[0017] The sides of the connecting base plate 1 are provided with vertically distributed mounting holes. The mounting holes on the left and right sides of the connecting base plate 1 can be used to install the photosensitive panel 2 and the laser module 3 respectively, which is convenient for installation and disassembly and can be reused.

[0018] like Figure 3As shown, the photosensitive panel 2 installed on each roadbed box 4 faces in the opposite direction of the laser irradiation from the laser module 3, which is a red laser. The photosensitive panel 2 of roadbed box B is used to receive the laser beam excited by the laser module 3 on the preceding roadbed box A. The laser irradiation from the laser module 3 on roadbed box B is directed toward the photosensitive panel 2 on the following roadbed box C. The photosensitive panel 2 can sense the position of the laser beam on the panel through photosensitive receivers distributed in a matrix to form a two-dimensional coordinate plane. The photosensitive panel 2 can be used in conjunction with wireless communication equipment to automatically collect and transmit data. For example, in conjunction with the attitude sensing module, it can sense the acceleration and angular velocity in three mutually perpendicular directions in space through a three-axis accelerometer and a three-axis gyroscope to calculate the direction and angle of the object being measured. In conjunction with the communication module, it is used for wireless communication to send or receive data signals. The entire device can power the other modules mentioned above through the power supply module and can also be connected to an external power supply.

[0019] Adjust the direction of the excitation beam of the laser module 3 to align with the center of the photosensitive panel 2 on the rear roadbed box 4. Collect data after the adjustment is completed. After the laser module 3 on each roadbed box 4 is adjusted, the two-dimensional coordinates determined by each photosensitive panel 2 are used as the initial value.

[0020] For example, in the initial state, the initial observation value PB0 of the excitation light beam of the equipment on the roadbed box A irradiates the photosensitive panel 2 of the roadbed box B is recorded as the initial displacement value of the roadbed box B relative to the roadbed box A, that is, P B0 (X0, Y0), the observation value of roadbed box B relative to roadbed box A at time i during the lifting operation is recorded as P Bi (X i , Y i ), the displacement value ΔP of roadbed box B relative to roadbed box A at time i during the lifting operation Bi (ΔX i , ΔY i ) can be obtained from ΔX i =X i -X0, ΔY i =Y i -Y0 is obtained, where ΔY i is the relative settlement difference between roadbed boxes A and B. By real-time monitoring of the settlement difference during the lifting operation, it is possible to determine whether the lifting machinery will overturn during the lifting operation.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
