Description

A bridge condition detection sensing device Technical Field

[0001] This utility model relates to the field of construction, specifically to a bridge condition detection and sensing device. Background Technology

[0002] In order to cross rivers more stably, various bridges are often built over existing roads. Different bridges have different load-bearing capacities. If a bridge is overloaded during use, it is easy to cause deformation or even collapse, especially bridges that have been neglected for many years. Therefore, for some bridges that have been built for a long time, inspectors are dispatched every once in a while to check the condition of the bridge in order to determine whether the bridge needs to be listed as a target for demolition.

[0003] Existing bridge inspection solutions often use non-contact deflection measuring instruments to conduct non-contact detection of bridges. To ensure the stability of the non-contact deflection measuring instrument during measurement, it is usually fixed with a tripod and the bridge is inspected and analyzed by a corresponding analyzer.

[0004] Currently, non-contact deflection measuring instruments generally require two people to operate: one to operate the analyzer for data parsing, and the other to operate the non-contact deflection measuring instrument to detect the bridge from multiple angles. This operating method greatly affects the efficiency of the inspection and wastes human resources. Summary of the Invention

[0005] The technical problem this invention aims to solve is that existing bridge condition detection and sensing devices require multiple operators, which greatly affects work efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a bridge condition detection and sensing device, including a deflection non-contact measuring instrument, a tripod for fixing the deflection non-contact measuring instrument, and an analyzer for receiving data from the deflection non-contact measuring instrument. Above the tripod, there is an elevation adjustment component and a rotation component for controlling the angle of the deflection non-contact measuring instrument. The rotation component includes a T-shaped column passing through the tripod and a rotation motor connected to the thin column end of the T-shaped column through a pin structure. The output shaft of the rotation motor passes through the tripod and the thin column end of the T-shaped column.

[0007] The elevation angle adjustment assembly includes a measuring instrument slide plate connected to the top surface of a T-shaped column via a pin structure and an elevation angle motor connected to the measuring instrument slide plate via a connecting key. Both the elevation angle motor and the rotation motor are connected to the analyzer via data cables.

[0008] As an improvement, the bottom surface of the non-contact deflection measuring instrument is provided with a convex slider corresponding to the measuring instrument slide plate, and the top surface of the convex slider is provided with a buckle to prevent the convex slider from sliding out.

[0009] As an improvement, the lens of the non-contact deflection measuring instrument is a detachable national standard lens.

[0010] As an improvement, the self-rotating motor and the bottom surface of the tripod, as well as the elevation motor and the top surface of the T-shaped column, are all connected by a bolt structure.

[0011] As an improvement, the top surface of the non-contact deflection measuring instrument is provided with a lifting handle for easy installation.

[0012] As an improvement, the deflection non-contact measuring instrument adopts the RSM-FBN large facility deflection non-contact measuring instrument.

[0013] The advantages of this invention compared to the prior art are as follows: This device adjusts the detection position of the deflection non-contact measuring instrument using a rotation motor and an elevation motor on a tripod. The rotation motor and elevation motor can be remotely controlled by an analyzer. This allows the deflection non-contact measuring instrument to be used for data detection and analysis and to adjust the detection position of the instrument simultaneously after assembly, requiring only one person.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] As shown in Figures 1, 2, 3, and 4 of the instruction manual, non-contact methods are frequently used for bridge quality inspection at present. This method is not only safe but also convenient for operators to adjust the detection range. Currently, bridge condition detection commonly uses a deflection non-contact measuring instrument 1, such as the RSM-FBN large facility deflection non-contact measuring instrument. While detecting the bridge, it also has a detachable national standard lens, which facilitates the adjustment of different magnifications. In order to facilitate the detection of the deflection non-contact measuring instrument 1, the top surface of the deflection non-contact measuring instrument 1 is provided with a lifting handle 12 for easy installation. This facilitates the stability of the deflection non-contact measuring instrument 1 during detection and also facilitates the connection between the deflection non-contact measuring instrument 1 and the tripod 2. The tripod 2 is used to ensure the stability of the deflection non-contact measuring instrument 1 during monitoring.

[0021] To facilitate the self-adjustment of the detection direction of the non-contact deflection measuring instrument 1, an elevation adjustment component 4 and a rotation component 5 for controlling the angle of the non-contact deflection measuring instrument 1 are installed above the tripod 2. The rotation component 5 includes a T-shaped column 51 passing through the tripod 2 and a rotation motor 52 connected to the thin end of the T-shaped column 51 by a pin structure. The output shaft of the rotation motor 52 passes through the tripod 2 and the thin end of the T-shaped column 51. The rotation angle of the T-shaped column 51 is controlled by the rotation of the rotation motor 52, that is, the self-rotation of the non-contact deflection measuring instrument 1 is controlled.

[0022] The elevation angle adjustment assembly 4 includes a measuring instrument slide plate 41 connected to the top surface of the T-shaped column 51 via a pin structure, and an elevation angle motor 42 connected to the measuring instrument slide plate 41 via a connecting key, thereby controlling the up and down elevation angles of the deflection non-contact measuring instrument 1. The T-shaped column 51 has a concave groove at its top, and the bottom surface of the measuring instrument slide plate 41 has a protrusion inserted into the concave groove. A pin is then used to connect the protrusion and the concave groove in series. The protrusion is connected to the pin rod via a connecting key, and the pin rod is connected via a rotating shaft. The bearing is connected to the side hole of the concave groove; in order to realize single-person operation of the deflection non-contact measuring instrument 1, the elevation motor 42 and the rotation motor 52 are both connected to the analyzer 3 through data cables. The elevation motor 42 and the rotation motor 52 are remotely controlled through the adjustment system of the analyzer 3. The rotation motor 52 is connected to the bottom surface of the tripod 2 and the pin fixing plate of the elevation motor 42 and the top surface of the T-shaped column 51 through a bolt structure, so as to facilitate the independent disassembly of the rotation motor 52 and the elevation motor 42.

[0023] To facilitate the connection between the measuring instrument slide plate 41 and the deflection non-contact measuring instrument 1, the bottom surface of the deflection non-contact measuring instrument 1 is provided with a convex slider 11 corresponding to the measuring instrument slide plate 41, and the top surface of the convex slider 11 is provided with a buckle 111 to prevent the convex slider 11 from sliding out. The measuring instrument slide plate 41 is locked by the buckle 111 to ensure that the deflection non-contact measuring instrument 1 will not slide out of the measuring instrument slide plate 41 when adjusting the elevation angle.

[0024] In the specific implementation of this utility model, the tripod 2 is placed at the required observation position, and then the height and flatness of the tripod 2 are adjusted to make the non-contact measuring instrument 1 horizontal, ensuring the stability of the detection data. Then, the analyzer 3 is used to adjust the rotation motor 52 and the elevation motor 42 to determine multiple different detection points, and the image data captured by the non-contact measuring instrument 1 is analyzed and monitored by the analyzer 3.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
