Description

Technical Field

[0001] This utility model relates to the field of bridge monitoring technology, and in particular to a data acquisition station for bridge monitoring. Background Technology

[0002] During long-term use, bridges are affected by various factors such as the natural environment and traffic loads, requiring regular and comprehensive monitoring to ensure their safe operation.

[0003] Traditional bridge monitoring methods mainly rely on manual inspections and periodic testing. This method has many limitations, including low efficiency and the presence of errors. In order to overcome the shortcomings of traditional monitoring methods, bridge health monitoring systems based on advanced technologies have emerged in recent years. These systems install various sensors and data acquisition devices on the bridge. The data acquisition station is mainly responsible for acquiring data from various sensors installed on the bridge (such as displacement sensors, stress sensors, vibration sensors, etc.) to collect the bridge's structural response data, environmental parameters, etc. in real time. With the help of advanced data processing and analysis algorithms, it can achieve comprehensive and real-time monitoring of the bridge's health status.

[0004] However, currently, most data acquisition stations are installed on the side of the bridge using bolts or welding. This makes it difficult to inspect and maintain the inside of the acquisition station, requiring the use of scaffolds or other equipment to lower workers to the side for operation. This is not only cumbersome but also poses certain safety hazards. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the cumbersome process of inspecting and maintaining the inside of the data acquisition station, which requires the use of scaffolds or other equipment to lower workers to the side for operation. This is not only tedious but also poses certain safety hazards. Therefore, this invention proposes a data acquisition station for bridge monitoring.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A data acquisition station for bridge monitoring includes a data acquisition station comprising an L-shaped mounting plate and a data acquisition and analysis instrument body. The L-shaped mounting plate is installed on the side of the bridge body, and the data acquisition and analysis instrument body is located inside the L-shaped mounting plate.

[0008] A lifting assembly is used to lift the main body of the data acquisition and analysis instrument. The lifting assembly is set on the bottom inner wall of the L-shaped mounting plate. The lifting assembly includes multiple sets of brackets and multiple telescopic rods. The bottom ends of the multiple telescopic rods are fixedly set on the bottom inner wall of the L-shaped mounting plate.

[0009] The storage box is used to store the wire harness. The storage box is located below the main body of the data acquisition and analysis instrument. The storage box has multiple compartments inside. The compartments have an outer cylinder inside, and the wire harness is wound around the outer wall of the outer cylinder. The bottom of the L-shaped mounting plate has a through hole.

[0010] In one possible design, an L-shaped connecting plate is fixedly installed on the back of the acquisition and analysis instrument body, and a top plate is fixedly installed on one side of the L-shaped connecting plate. Each set of brackets includes a first rotating plate and a second rotating plate, and one end of the first rotating plate and one end of the second rotating plate are rotatably set. The other end of the second rotating plate and the other end of the first rotating plate in the adjacent set are both fixedly set with connecting shafts. Gears are fixedly sleeved on the outer wall of the connecting shafts. The ends of two adjacent connecting shafts are rotatably set on the outer wall of the same section of the multi-section telescopic rod. The two adjacent gears mesh with each other. The end of the second rotating plate located above is rotatably set at the bottom of the top plate.

[0011] In one possible design, the lifting assembly also includes a servo motor, with the end of the lower rotating plate fixedly sleeved on the outer wall of the output shaft of the servo motor.

[0012] In one possible design, the outer wall of the outer cylinder is fixedly provided with a buckle, and the middle of the wire harness is fixed by the buckle. Both ends of the wire harness are wound around the outer wall of the outer cylinder in the same direction, and the two ends of the wire harness slide through the top and bottom of the storage box respectively.

[0013] In one possible design, an inner rod is fixedly installed inside the cavity, and an outer cylinder is rotatably sleeved on the outer wall of the inner rod. A torsion spring is sleeved on the outer wall of the inner rod, and the two ends of the torsion spring are respectively fixed on the outer wall of the inner rod and the inner wall of the outer cylinder.

[0014] In one possible design, a U-shaped protective plate is fixedly installed on the inner wall of the L-shaped mounting plate, and the data acquisition and analysis instrument body, L-shaped connecting plate, top plate, storage box and lifting assembly are all located inside the U-shaped protective plate.

[0015] In this application, during actual use, the back of the L-shaped mounting plate is fixed to the side of the bridge body using existing methods, such as bolt drilling. After the sensor wiring harness extends into the corresponding cavity, the middle part is fixed by a snap-fit ​​clamping method. Then, both ends of the wiring harness are wound in the same direction, and the other end extends to the outside of the storage box and connects to the main body of the data acquisition and analysis instrument. When it is necessary to inspect and repair the inside of the main body of the data acquisition and analysis instrument, the servo motor is controlled to drive the bottom set of brackets to rotate and open. When the unfolding angle of the second rotating plate in the bottom set of brackets changes, it will rotate along with the connecting shaft located at one end of the second rotating plate. The connecting shaft drives the gear to rotate, and the connection... The shaft drives one of the corresponding sections of the telescopic rod to move upward, allowing the upper support to move upward after the lower support is deployed. When the lower support is deployed, it drives the gear to rotate, which in turn drives the gear in the upper support to rotate, thus enabling the upper support to deploy. This process continues until the top plate moves upward. The top plate, through the L-shaped connecting plate, drives the data acquisition and analysis instrument to move upward, allowing the data acquisition and analysis instrument to be raised above the side of the bridge body. This eliminates the need to use scaffolding or other equipment to go down and inspect, improving efficiency and ensuring worker safety. When the data acquisition and analysis instrument moves upward, it pulls the wiring harness. At this time, the wiring harness wrapped around the outer wall of the outer cylinder will be stretched to match the lifting and lowering movement of the data acquisition and analysis instrument.

[0016] In this utility model, the data acquisition station for bridge monitoring can be raised by a lifting component after the equipment is installed on the side of the bridge. When maintenance or inspection is required, the main body of the acquisition and analysis instrument can be raised by the lifting component for operation, avoiding the need for traditional equipment with scaffolds, which is not only cumbersome but also poses certain safety hazards.

[0017] In this utility model, the data acquisition station for bridge monitoring can collect and wind the wire harness around the outer wall of the outer cylinder through the storage box. When the acquisition and analysis instrument body moves upward, both ends can be stretched to achieve the displacement of the acquisition and analysis instrument body. When the acquisition and analysis instrument body moves downward, the outer cylinder can be rotated by the torsion spring to rewind and collect the wire harness.

[0018] In this utility model, when in use, the L-shaped mounting plate on the back of the device is first installed on the bridge body. When it is necessary to maintain and inspect the main body of the data acquisition and analysis instrument, the main body of the data acquisition and analysis instrument can be moved upward by the lifting component, thereby avoiding the need for equipment such as a hoist to go down for inspection, and ensuring the installation of personnel.

[0019] Furthermore, the wire harness can be wound and collected on the outer wall of the outer cylinder, and can be stretched and extended when the main body of the data acquisition and analysis instrument rises, so as to cooperate with the movement of the main body of the data acquisition and analysis instrument.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Reference Figure 1-3 A data acquisition station, used in the field of bridge monitoring, includes: an L-shaped mounting plate 2 securely mounted on the side of the bridge body by appropriate fasteners such as bolts or welding; an acquisition and analysis instrument body 4 placed inside the L-shaped mounting plate 2; an L-shaped connecting plate 5 fixedly installed on the back of the acquisition and analysis instrument body 4; and a top plate 11 fixedly installed on one side of the L-shaped connecting plate 5, so that the top plate 11 can be moved by a lifting assembly, thereby achieving the lifting effect of the acquisition and analysis instrument body 4.

[0030] The lifting component controls the lifting and lowering displacement of the data acquisition and analysis instrument body 4, so that when the data acquisition and analysis instrument body 4 needs to be maintained and inspected, the data acquisition and analysis instrument body 4 can be moved upward by the lifting component, thereby avoiding the need for equipment such as scaffolds to go down for inspection, and ensuring the installation of personnel.

[0031] Reference Figure 3 Specifically, the lifting assembly includes multiple sets of brackets. Each bracket is composed of a first rotating plate 10 and a second rotating plate 19 connected by a rotatable mechanism. These rotating plates are interconnected by a connecting shaft 9 and a gear 7 to form a driveable chain structure. Driven by a servo motor 8, the lowest set of brackets can rotate and open, and the brackets will drive the corresponding gear 7 to rotate and one section of the multi-section telescopic rod 6 to rise. Then, through the meshing gears, each rotating plate can rotate synchronously to realize the lifting and lowering of the data acquisition and analysis instrument body 4.

[0032] Reference Figure 5 To facilitate the management of the wiring harness and ensure that the harness extends accordingly when the data acquisition and analysis instrument 4 rises, a storage box 12 is installed below the data acquisition and analysis instrument body 4. The storage box 12 is divided into multiple compartments 15, and an outer cylinder 14 is installed in each compartment 15. The middle of the wiring harness is fixed by a buckle 16 on the outer wall of the outer cylinder 14. Both ends of the wiring harness are wound around the outer wall of the outer cylinder 14 in the same direction. The two ends of the wiring harness slide freely through the top and bottom of the storage box 12, respectively, which facilitates the connection between the sensor and the data acquisition and analysis instrument body 4.

[0033] Reference Figure 6 The outer cylinder 14 is sleeved on the outer wall of the inner rod 17, and the outer cylinder 14 and the inner rod 17 are connected by a torsion spring 18. In this way, the outer cylinder 14 can be easily rotated and automatically reset.

[0034] This application can be used in the field of bridge monitoring, or in other fields applicable to this application.

[0035] Example 2

[0036] refer to Figure 3 An improvement based on Example 1: A data acquisition station for bridge monitoring, which is applied to the field of bridge monitoring, has a U-shaped protective plate 3 fixed to the inner wall of the L-shaped mounting plate 2. This protective plate not only enhances the stability of the structure, but also forms a relatively closed space, effectively protecting the acquisition and analysis instrument body 4 and its related components from external interference and damage.

[0037] However, as is well known to those skilled in the art, the working principle and wiring method of the servo motor 8 are commonplace and are all conventional methods or common knowledge. Therefore, they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
