Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, and in particular to a bridge superstructure detection device based on guide rail sliding. Background Art

[0002] The complex interweaving of multiple factors on bridge structures, including aging of concrete materials, frequent vehicle overloading, and harsh operating environment, inevitably leads to various diseases of in-service bridges, such as cracking, peeling of protective layers, water seepage and alkali efflux, and exposed reinforcement corrosion. These diseases pose a severe test to the safety and durability of bridges. Therefore, it is crucial to detect defects in bridge structures as early as possible to prevent further reduction of their structural bearing capacity and durability. Structural apparent diseases are usually the most obvious signs that the structure may be deteriorating or damaged. At the same time, they are also key evaluation indicators in bridge technical condition assessment manuals such as "Highway Bridge Technical Condition Assessment Standard" (JTG / TH21-2011), "Highway Bridge and Culvert Maintenance Code" (JTG / H11-2004), and "Urban Bridge Inspection and Assessment Technical Code" (CJJ / T233-2015).

DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0029] Embodiment 1:

[0030] like Figure 1-5 As shown, the bridge superstructure detection device based on guide rail sliding provided by the utility model includes: a track 5 and a detection mechanism 6, the detection mechanism 6 is installed on the I-shaped track 5, and moves along the track 5 to detect the bridge, the track is installed below the wet joint 4 between the box beams 3 (it can also be installed at other types of bridge joints) or on the side of the box beam 3. This embodiment takes the installation below the wet joint 4 as an example, the box beam 3 is installed on the cap beam 2, the cap beam 2 is fixed to the ground through the pier 1, and a support is installed between the box beam 3 and the cap beam 2. The detection mechanism 6 can adopt the structure disclosed in CN117705800A, which will not be described again here. In detail, the detection mechanism 6 uses a camera to film or photograph the bridge (box girder 3, wet joint 4 and support), and uses a computer to identify the bridge disease picture to detect the bridge. Since the detection mechanism 6 is located in the gap between the side-by-side box girders 3, it is convenient to detect the inner side of the box girder 3, and since the detection mechanism 6 and the track 5 are both located below the bridge deck, the detection process is not affected by the wet joint 4 and will not affect the normal traffic on the bridge. There is no need to implement measures such as road closures, and the impact on traffic is smaller. Therefore, the device is more suitable for use on box girder bridges and other bridges with similar structures in which multiple box girders are parallel and interconnected.

[0031] By setting the track 5 and the detection mechanism 6 installed below the wet joint 4, the device is installed at the wet joint below the bridge deck. It does not occupy the traffic space on the bridge deck and has no impact on traffic. There is no need to change the bridge structure. It can be installed on various types of bridges. It has strong versatility and can easily detect the upper part of the beam and the details of the support, making it easy to judge the use of the bridge.

[0032] Embodiment 2:

[0033] like Figure 2As shown, the detection mechanism 6 includes a detection vehicle 7, which is installed on a track 5 and can move on the track 5. The detection vehicle 7 is controlled by a wireless remote control. An adjustment component 8 is installed below the detection vehicle 7, and a recording component 9 is installed below the adjustment component 8. The adjustment component 8 is used to adjust the height (angle) of the recording component 9. In this embodiment, the adjustment component 8 is a mechanical arm. The detection vehicle 7 is equipped with a battery to power all devices on the detection vehicle 7. The entire device is remotely controlled by a remote controller. The mechanical arm is installed on the detection vehicle 7. The mechanical arm is a six-axis mechanical arm. In addition to rotation, the mechanical arm can be extended and retracted. The remote controller remotely controls the rotation and extension of the mechanical arm. The mechanical arm controls the height, position and recording angle of the recording component 9. The 360-degree camera on the recording component 9 records the specific details of the box girder 3, the wet joint 4, the support and the bottom of the top surface of the bridge, and then the computer connected to it performs detection and analysis on the bridge.

[0034] By providing the detection mechanism 6 including the detection vehicle 7, the adjustment component 8 and the video recording component 9, the height or angle of the video recording component 9 can be conveniently adjusted to detect the details of the bridge.

[0035] Embodiment 3:

[0036] like Figure 3 As shown, the recording component 9 includes a mounting frame 10, which is connected to the bottom of the adjustment component 8. A front camera 11 and a rear camera 12 are obliquely installed on the mounting frame 10, and a lower camera 13 is installed at the bottom of the mounting frame 10. When in use, the front camera 11, the rear camera 12 and the lower camera 13 are all wide-angle cameras. The front camera 11 and the rear camera 12 record the top of the mounting frame 10, and the lower camera 13 records the bottom of the mounting frame 10. The height and angle of the mounting frame 10 are adjusted by the adjustment component 8, which can facilitate bridge inspection, especially the gaps between box girders and the details of the supports.

[0037] By setting up a recording component 9 including a mounting frame 10, a front camera 11, a rear camera 12 and a lower camera 13, the bridge can be photographed simultaneously by multiple cameras, so that the adjustment component 8 does not need to adjust the height or angle too much, and 360-degree photography of the bridge can be achieved.

[0038] Embodiment 4:

[0039] like Figure 2 As shown, the adjustment component 8 is an electric telescopic rod, and its two ends are respectively connected to the inspection vehicle 7 and the mounting frame 10. When in use, the electric telescopic rod is started by remote control to make it extend and retract, thereby controlling the height of the mounting frame 10, and then controlling the height of the recording component 9. When used in conjunction with the recording component 9 in Example 3, the height of multiple cameras can be controlled to shoot the bridge.

[0040] By setting the adjustment component 8 as an electric telescopic rod, the height of the recording component 9 can be controlled, making it convenient for the camera to record the bridge.

[0041] Embodiment 5:

[0042] like Figure 2 As shown, the inspection vehicle 7 is equipped with a running wheel 15, a positioning wheel 17 and a driving motor 16. The running wheel 15 is connected to the output shaft of the driving motor 16. The running wheel 15 moves on the running surface 18 of the track 5. The positioning wheel 17 contacts the bottom of the track 5, so that the inspection vehicle 7 can move stably. When in use, the driving motor 16 starts to drive the running wheel 5 to rotate, thereby moving the inspection vehicle 7. Since the positioning wheel 17 consists of two and fits with the bottom of the track 5, the inspection vehicle 7 can move stably on the track 5. Similarly, the driving motor 16 is controlled by a wireless remote control.

[0043] By installing the running wheels 15 , the positioning wheels 17 and the driving motor 16 on the inspection vehicle 7 , the inspection vehicle 7 can stably run on the track 5 .

[0044] Embodiment 6:

[0045] like Figure 4-5 As shown, the track 5 is symmetrically provided with mounting grooves 19 near the end, and a detachable mounting plate 20 is installed on the mounting grooves 19. Positioning grooves 21 are provided on both sides of the mounting grooves 19, and positioning holes (not shown) are vertically provided in the positioning grooves 21. Positioning blocks 22 are integrally installed on both sides of the mounting plate 20, and a positioning column 23 is installed at the bottom of the positioning block 22. When in use, the positioning column 23 is aligned with the positioning hole and inserted so that the positioning block 22 is embedded in the positioning groove 21, and then the mounting plate 20 is embedded in the mounting groove 19, so that the top of the mounting plate 20 is flush with the walking surface 18, and the bottom is flush with the bottom of the track 5. The detection vehicle 7 can walk normally on the mounting plate 20, and the mounting plate 20 is removed from the mounting groove 19, and the walking wheel 16 of the detection vehicle 7 can be removed from the mounting groove 19, and then the detection vehicle 7 of the device is removed from the track 5 and taken away. The installation process is the opposite of that, and the process is not repeated here.

[0046] By providing the mounting groove 19 , the mounting plate 20 , the positioning groove 21 , the positioning block 22 and the positioning column 23 , the installation and disassembly of the detection vehicle 7 can be facilitated.

[0047] Embodiment 7:

[0048] like Figure 3 As shown, a plurality of fill lights 14 are installed on the mounting frame 10. The plurality of fill lights 14 are arranged at staggered positions, which can reduce the generation of shadows, provide fill light for the camera, and thus make the camera shooting clearer.

[0049] By installing a plurality of fill lights 14 on the mounting frame 10 , the video can be made clearer and the detection can be made more accurate.

[0050] Working principle: When in use, the remote control remotely controls the inspection vehicle 7 to move on the track 5; after the inspection vehicle 7 reaches the designated position, the remote control controls the adjustment component 8 so that the camera component 9 is in a position to clearly photograph the bottom and side of the box girder of the bridge to photograph the bridge defects; the fill light 14 is turned on, and the camera component 9 takes photos of the defects, which are then transmitted to the terminal system through the network; the operator records the information notes of the defect photos in the terminal system to ensure accurate and standardized records of each defect; repeat the above steps and continue to observe the defects at the next point until the entire bridge inspection process is completed.
