Description

Technical Field

[0001] This utility model relates to the field of stress monitoring device technology, specifically a stress monitoring device for key nodes of a steel platform. Background Technology

[0002] The detachable and mobile steel platform for connecting corridor construction can be installed on the crossbeams at the top of the main steel structure of the connecting corridor during the construction of the exterior walls of municipal connecting corridor projects. The crossbeams are used as track beams for movement, allowing workers to carry out construction. Through the stress monitoring device at the key nodes of the steel platform, stress and displacement can be monitored at the key stress and easily deformable locations of the steel platform. Based on the monitoring results, the safety and reliability of the steel platform during the construction process can be evaluated, providing data and technical support for the use of the steel platform for connecting corridor construction and the safe construction of the connecting corridor.

[0003] Existing stress monitoring devices for key nodes of steel platforms can obtain the key stress and deformation locations of the steel platform during construction through the analysis results of the finite element model of the steel structure and the structural stress characteristics. Multiple vibrating wire strain sensors installed at these key stress and deformation locations accurately capture the strain changes in the structure. However, these existing devices involve not only sensors but also data acquisition, transmission, and analysis. The sensors need to collect the strain data via cables to a ground-based data collection and analysis device. Since the steel platform needs to be moved, the cables installed on it are numerous and long. These long cables require regular inspection and maintenance, which is time-consuming and labor-intensive. Furthermore, the large number of long cables increases the possibility of electrical leakage, reducing the safety of the steel platform. Therefore, this paper proposes a new stress monitoring device for key nodes of steel platforms to address these issues. Utility Model Content

A second wireless data transceiver 35 is fixedly connected to the upper side of the mounting bases 34. A connection line 4 is provided between the stress monitoring component 3 and the monitoring end power supply component 2. The connection line 4 includes a cable 41. A first plug 42 is fixedly connected to the rear end of the cable 41, and a second plug 43 is fixedly connected to the front end of the cable 41.

[0022] The main body 1 of the detection device includes a data analysis device 11 with a carrying plate 12 fixedly connected to its upper side. A first wireless data transceiver 13 is fixedly connected to the upper side of the carrying plate 12. Multiple first carrying slots are provided on the upper side of the carrying plate 12, and second carrying slots are provided in front of each of the first carrying slots. The first wireless data transceiver 13 and the data analysis device 11 are electrically connected. The data analysis device 11 can analyze the acquired data and assess the safety and reliability of the steel platform construction process based on the data analysis results. The welding frames 21 are all L-shaped frames. The photovoltaic modules 23 all include photovoltaic panels and photovoltaic charging controllers electrically connected to the photovoltaic panels. The photovoltaic charging controllers of the photovoltaic modules 23 are all electrically connected to the storage batteries 24. The photovoltaic module 23 and the battery 24 can power the strain sensor 33 and the second wireless transceiver 35; the welding ends 32 at both ends of the vibrating wire 31 are symmetrically distributed, and the second wireless transceiver 35 is electrically connected to the strain sensor 33. The second wireless transceiver 35 is matched with the first wireless transceiver 13, and data exchange can be performed with the first wireless transceiver 13 through the second wireless transceiver 35; the cables 41 are all wound on the winding device 25, the first plugs 42 are all inserted into the battery 24, and the second plugs 43 are all inserted into the strain sensor 33. The battery 24 and the strain sensor 33 can be electrically connected through the cables 41 and the first plugs 42 and the second plugs 43.

[0023] Workflow: Each photovoltaic module 23 of this device includes a photovoltaic panel and a photovoltaic charging controller electrically connected to the photovoltaic panel. The photovoltaic charging controllers of each photovoltaic module 23 are electrically connected to the battery 24. The vibrating wire 31, welding ends 32, and strain sensors 33 of this device can constitute a vibrating wire strain gauge. Vibrating wire strain gauges are existing equipment, and all of the above are existing technologies. Before use, multiple monitoring end power supply components 2 and stress monitoring components 3 are installed at the key stress and deformation locations of the steel platform. Specifically, the paired welding ends 32 are bolted to both ends of the vibrating wire 31, and the paired welding ends 32 are welded to the key stress and deformation locations of the steel platform. The photovoltaic module 23 is positioned on both sides of the main force and deformation location. The welding frame 21 is then welded to the edge of the steel platform, oriented so that the photovoltaic module 23 faces the sun. The first plug 42 is then inserted into the battery 24, and the cable 41 is wound around the winder 25, leaving an appropriate length of cable 41. Finally, the second plug 43 is inserted into the strain sensor 33, and the device is ready for use. When using this device, the photovoltaic module 23, fixed by the support shaft 22, can absorb solar energy and convert it into electrical energy. The battery 24, fixed by the welding frame 21, can store this electrical energy and power the strain sensor 33 and the second wireless transceiver 35. Stress monitoring can be performed by welding pairs of ends 32 on both sides of the main stress direction at key stress and deformation locations of the steel platform. When stress changes or deformations occur at these locations, the pairs of welded ends 32 undergo relative displacement, causing the vibrating wire 31 to deform. The strain sensor 33 can then detect the stress change and transmit the monitoring data to the first wireless data transceiver 13 fixed to the platform 12 via the second wireless data transceiver 35, which is fixed to the mounting base 34. The data analysis device 11 can then acquire and analyze the data, and can use the analysis results to guide the construction of the steel platform. The safety and reliability of the process are assessed. The device can power the strain sensor 33 and the second wireless data transceiver 35 through the photovoltaic module 23 and the battery 24. The cable 41 is stored through the winding device 25, and data is exchanged in conjunction with the first wireless data transceiver 13 through the second wireless data transceiver 35. This greatly reduces the number and length of the cables 41 on the steel platform. The staff only need to perform regular inspections and maintenance on a small number of short cables 41, which saves time and effort. Moreover, the fewer and shorter cables 41 can greatly reduce the possibility of leakage, thereby improving the safety of the steel platform.
