Description

Technical Field

[0001] This utility model belongs to the field of bridge engineering technology, and in particular relates to a multifunctional monitoring support. Background Technology

[0002] With the large-scale construction of transportation infrastructure in my country, an increasing number of bridge structures have been built, such as bridges spanning rivers, seas, municipal bridges, railway bridges, and highway bridges. As their service life increases, and due to long-term overloading and insufficient maintenance, the phenomenon of bridge defects in my country is growing daily. Once bridge defects occur, such as pier settlement, bridge beam collapse, and bridge flexural deformation, they will threaten the safety of pedestrians and vehicles on the bridge. Existing technology (CN2023109442069 A method for monitoring and repairing bridge settlement) can only monitor bridge force values, with limited functionality; although there are periodic manual inspections, it cannot achieve all-weather monitoring. Furthermore, with the large number of bridges, the manual inspection cycle is long, and sometimes it is difficult to directly determine the safety of the bridge. Therefore, those skilled in the art urgently need to research a multifunctional monitoring bearing that can comprehensively monitor the bearing status. Utility Model Content

[0003] In view of this, the present invention provides a multifunctional monitoring support to solve the above problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A multifunctional monitoring support includes: an upper structure, a rubber pad, a base, and a monitoring system, wherein the rubber pad is disposed in the base and the upper structure is disposed on the upper surface of the rubber pad; The monitoring system includes a pressure transmitter, an inclination sensor, a draw wire sensor, a data acquisition and transmission module, a cloud server, and a monitoring platform; The bottom wall of the basin is provided with at least two monitoring oil paths, which are used for oil inlet and installation of the pressure transmitter, respectively. The monitoring oil paths are connected to the oil film in the basin. The pressure transmitter is installed at the external port of the monitoring oil path to collect the oil film pressure signal in real time and monitor the vertical bearing capacity borne by the support. The bottom surface of the upper structure is equipped with multiple tilt sensors and pull-wire sensors, which are arranged in an alternating manner. The data acquisition and transmission module is electrically connected to the pressure transmitter, tilt sensor and draw wire sensor, and is used to acquire and process pressure, angle and displacement signals, and upload the data to the cloud server via wireless communication. The monitoring platform is installed on a cloud server and is used to display the collected force, rotation, and displacement data, as well as the daily extreme values ​​of the monitored items in real time.

[0005] Furthermore, the tilt sensor is a medium-precision current-type dual-axis tilt sensor with built-in electromagnetic interference suppression circuitry.

[0006] Furthermore, the pull-wire sensor is an IP68 waterproof pull-wire displacement sensor.

[0007] Furthermore, the pull-wire sensor includes a stainless steel pull rope and a precision rotation sensor. The stainless steel pull rope is connected to the precision rotation sensor and installed on the bottom surface of the upper structure. One end of the stainless steel pull rope is fixed to the upright plate of the base basin.

[0008] Furthermore, the monitoring system also includes an alarm device, which is electrically connected to the monitoring platform. When the data collected by the data acquisition and transmission module exceeds a preset limit value, an audible and visual alarm and a pop-up reminder on the monitoring platform page are triggered.

[0009] The beneficial effects of this utility model are as follows: This invention can simultaneously monitor three parameters of the bearings: force, rotation angle, and displacement, achieving comprehensive monitoring of the bridge's condition. Through an automated monitoring system, it enables real-time monitoring around the clock, eliminating the need for periodic manual inspections and significantly improving monitoring efficiency. The data acquisition and transmission module can compare and calculate the collected data to determine daily extreme values. When these values ​​exceed the set limits, it triggers audible and visual alarms and pop-up alerts, providing early warnings for bridge safety. This invention, through real-time monitoring of the bearings' condition, can detect potential safety hazards in bridges early, ensuring the safety of pedestrians and vehicles. It also boasts advantages such as simple structure, convenient installation, and ease of widespread adoption. Attached Figure Description

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] See attached document Figure 1-3 This utility model provides a multifunctional monitoring support, which adds the function of monitoring force, rotation angle and displacement to the ordinary pot bearing. It includes: an upper structure 10, a rubber pad 20, a base 30 and a monitoring system. The rubber pad 20 is disposed in the base 30, and the upper structure 10 is disposed on the upper surface of the rubber pad 20. The upper structure 10 is not limited to... Figure 1 and Figure 2 The system includes one structure, but also other structures; the monitoring system includes a pressure transmitter 41, an inclination sensor 42, a drawwire sensor 43, a data acquisition and transmission module, a cloud server, and a monitoring platform; the bottom wall of the basin 30 has at least two monitoring oil passages 31, which are used for oil inlet and installation of the pressure transmitter 41, respectively. The monitoring oil passages 31 are connected to the oil film 32 in the basin 30. The pressure transmitter 41 is installed at the external port of the monitoring oil passage 31 to collect the pressure signal of the oil film 32 in real time and monitor the vertical bearing capacity of the support; multiple inclination sensors 42 and drawwire sensors 43 are installed on the bottom surface of the upper structure 10, and the two are arranged alternately; the data acquisition and transmission module is electrically connected to the pressure transmitter 41, inclination sensor 42, and drawwire sensor 43 to collect and process pressure, angle, and displacement signals, and upload the data to the cloud server through wireless communication; the monitoring platform is installed on the cloud server to display the collected force, angle, and displacement data, as well as the daily extreme values ​​of the monitored items in real time.

[0014] This invention can monitor both the vertical force transmitted from the bridge to the piers and the rotation and displacement of the supports.

[0015] The pressure transmitter 41 is installed at the external port of the monitoring oil circuit 31. The pressure transmitter 41 collects the simulated pressure signal of the oil film 32 in real time, and uploads it to the cloud server through the data acquisition and transmission module. Finally, the monitoring platform dynamically displays the real-time data and the daily pressure extreme value, thereby achieving the purpose of monitoring the support force value.

[0016] The tilt sensor 42 employs a medium-precision current-type dual-axis tilt sensor. This sensor incorporates a high-precision inclinometer unit, converting the acquired values ​​into a current signal output. Secondary correction and linear compensation are performed by the internal MCU control system, and anti-electromagnetic interference circuitry ensures long-term stable operation in harsh industrial environments. The tilt sensor 42 acquires analog signals of the support rotation angle in real time, transmitting them to a cloud server via a data acquisition and transmission module. Real-time data and daily extreme angle values ​​are displayed on the monitoring platform, achieving the purpose of monitoring the support rotation angle.

[0017] The pull-wire sensor 43 adopts a high-precision IP68 waterproof pull-wire displacement sensor from Breit. Its principle is to convert mechanical motion into an electrical signal that can be measured, recorded, or transmitted. Its structure consists of a stainless steel pull rope 431 connected to a precision rotation sensor 432 and installed on the bottom surface of the upper structure 10. One end of the stainless steel pull rope 431 is fixed to the upright plate 33 of the base 30. When the upper structure 10 and the base 30 move, the stainless steel pull rope 431 extends and retracts. The stainless steel pull rope 431 drives the precision rotation sensor 432 to rotate, outputting an electrical signal proportional to the distance the stainless steel pull rope 431 moves. The data acquisition and transmission module acquires the displacement data of the pull-wire sensor 43 in the form of electrical signals and uploads it to the cloud server. The monitoring platform dynamically displays real-time data and daily displacement extreme values, thereby achieving the purpose of monitoring support displacement.

[0018] The data acquisition and transmission module compares and calculates the collected vertical bearing capacity, rotation angle, and displacement values ​​to obtain the daily extreme values. If the collected values ​​exceed the set limits, there will be an audible and visual alarm and a pop-up reminder on the page. The data is then transmitted to the cloud server via wireless communication. The monitoring platform is installed on the cloud server, and the collected data can be displayed in real time through the monitoring platform.
