Description

Technical Field

[0001] This utility model relates to the field of stress monitoring device structure technology, and in particular to a stress monitoring device for bridge bearings. Background Technology

[0002] Bridges, as vital transportation infrastructure, play a crucial role in modern society. Bridge bearings, as key components connecting bridges and piers, directly impact the stability and safety of the bridge. Elastic damping bridge bearings are devices that utilize the properties of elastic materials to absorb and disperse vibrational energy. They are typically installed at the bottom of the bridge or key connection points, and through their unique structure and material properties, they effectively reduce the bridge's vibration response when subjected to external forces.

[0003] In bridge structures, bearings are key components connecting the superstructure and substructure, bearing enormous vertical loads, horizontal shear forces, and potential torsional forces. The combined effect of these forces makes bearings one of the most vulnerable components in a bridge. Therefore, real-time monitoring of the stress state of bridge bearings and timely detection and warning of potential safety hazards are of great significance for ensuring the normal operation of bridges.

[0026] Reference Figure 1 - Figure 3 As an embodiment of the present invention, a stress monitoring device for bridge bearings is provided, including a load-bearing unit 100 and a monitoring and damping unit 200.

[0027] The load-bearing unit 100 includes a load-bearing base 101 and a storage frame 102 fixedly connected to the upper surface of the load-bearing base 101. The upper surface of the storage frame 102 is provided with an insertion slot 105. A stress monitor 103 is fixedly connected to one side of the storage frame 102. The stress monitor 103 and the pressure sensor 211 monitor the stress state of the bridge support. The storage frame 102 is provided with a lifting slot 104. There are two sets of lifting slots 104, and both sets of lifting slots 104 are symmetrical about the center of the storage frame 102.

[0028] The stress monitoring unit 200 includes a buffer pressure column 202 fixedly connected inside a storage frame 102, and a lifting plate 209 fixedly connected to the upper surface of the buffer pressure column 202. A load-bearing top plate 201 is fixedly connected to the upper surface of the lifting plate 209. The load-bearing top plate 201 first bears the load and then transmits the load to the buffer pressure column 202 inside the storage frame 102. The buffer pressure column 202 is compressed by the force, pushing the lifting plate 209 to move, which in turn pushes the load-bearing top plate 201 to move upward, thereby providing a certain degree of stress monitoring. To prevent the connecting column 206 from descending rapidly and causing damage to the equipment, the connecting column 206 is fixedly connected to the lower surface of the load-bearing top plate 201. The sliding grooves 205 on both sides of the connecting column 206 are connected to the connecting ring 208, so that the connecting ring 208 drives the adjusting rod 203 to rotate. Since one side of the extrusion frame 207 has an inclined structure, the extrusion frame 207 slides downward in the insertion groove 105, so that the extrusion frame 207 contacts the surface of the insertion groove 105 in the storage frame 102. Therefore, when the adjusting rod 203 rotates, The compression frame 207 compresses the push spring 210 to apply a certain preload to the bridge bearing. Sliding grooves 205 are hollowed out on both sides of the connecting column 206. A connecting ring 208 is rotatably connected inside the connecting column 206, and an adjusting rod 203 is rotatably connected inside the connecting ring 208. The compression frame 207 is fixedly connected to the outer surface of the connecting ring 208, and the compression frame 207 is fixedly connected to the outer surface of the adjusting rod 203. A push spring 210 is fixedly connected to the side of the compression frame 207 closest to the connecting column 206. The other end of 10 is fixedly connected to one side of the connecting column 206. There are several pushing springs 210, and all of the pushing springs 210 are symmetrical about the center of the load-bearing seat 101. The insertion slot 105 has a conical trapezoidal structure. A detector 204 is embedded in one side of the insertion slot 105. A pressure sensor 211 is fixedly connected to one side of the detector 204. One side of the extrusion frame 207 has an inclined structure. A buffer pressure column 202 is fixedly connected in the lifting slot 104. A lifting plate 209 is slidably connected in the lifting slot 104.

[0029] When the equipment is working normally, when the bridge is subjected to external load, the load-bearing top plate 201 first bears the load and transfers the load to the buffer pressure column 202 in the storage frame 102. The buffer pressure column 202 is compressed by force, which pushes the lifting plate 209 to move up and down, thereby pushing the load-bearing top plate 201 to move upward, thus avoiding the rapid descent of the connecting column 206 to a certain extent, which could cause damage to the equipment.

[0030] At this time, the sliding grooves 205 on both sides of the connecting column 206 are connected with the connecting ring 208, so that the connecting ring 208 drives the adjusting rod 203 to rotate. Since one side of the extrusion frame 207 is an inclined structure, the extrusion frame 207 slides downward in the insertion groove 105, so that the extrusion frame 207 contacts the surface of the insertion groove 105 in the storage frame 102. Therefore, when the adjusting rod 203 rotates, the extrusion frame 207 extrudes and pushes the spring 210 to apply a certain preload to the bridge support.

[0031] Meanwhile, the stress monitor 103 and the pressure sensor 211 monitor the stress state of the bridge bearing. By adjusting the pressure inside the buffer pressure column 202, the height of the bridge bearing can be automatically adjusted. In addition, the conical trapezoidal groove structure embedded on one side of the detector 204 can ensure that the pressure sensor 211 is in close contact with the bearing surface, thereby improving the accuracy of the monitoring data.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
