DETAILED DESCRIPTION

[0030] 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.

[0031] Embodiment 1:

[0032] like Figure 1-7 As shown, the improved self-propelled bridge bottom surface crack detection device provided by the utility model comprises: a cantilever 2 and a walking trolley 4 installed at both ends of the cantilever 2, the cantilever 2 is placed under the bridge 1, the walking trolley 4 is arranged on both sides of the bridge 1, a hydraulic telescopic arm 5 is installed between the walking trolley 4 and the cantilever 2, and two detection mechanisms 3 are arranged on the cantilever 2. The detection mechanism 3 detects cracks on the bottom of the bridge. The detection mechanism 3 comprises a support frame 8 slidably installed on the cantilever 2, and a camera 9, two scrapers 10 and two fans 11 are installed on the support frame 8. The two fans 11 are respectively aimed at the camera 9 and directly above the camera 9. A first motor 6 is installed at one end of the cantilever 2, and a screw 7 is installed on the output shaft of the first motor 6. The screw 7 is connected to the support frame 8, and the other end of the screw 7 is rotatably connected to the cantilever 2. When in use, the two walking trolleys 4 are respectively installed on both sides of the bridge 1. The two ends of the cantilever 2 are supported and driven to move by means of two walking trolleys 4 and a hydraulic telescopic arm 5. Since the two ends of the cantilever 2 are supported at the same time, the cantilever 2 is more stable. The first motor 6 is started to drive the screw 7 to rotate, thereby causing the support frame 8 to move laterally on the cantilever 2. The camera 9 thereon records the bottom of the bridge and records the crack conditions of the entire bottom of the bridge. In addition, the hydraulic telescopic arm 5 is used to adjust the distance between the cantilever 2 and the bottom of the bridge 1 so that the scraper 10 contacts the bottom of the bridge. The scraper 10 scrapes off the moss and other debris on the bottom of the bridge to make the bottom of the bridge clean and tidy, making it convenient to check the bottom of the bridge. The fan 11 is started synchronously. One fan 11 blows air to the scraped bottom of the bridge to further clean the debris on the bottom of the bridge. The other fan 11 blows air towards the camera 9 to blow away the debris that falls on the camera 9, so that the camera 9 can take clear pictures and prevent the scraped debris from covering the camera 9.

[0033] By setting up a cantilever 2 and two walking trolleys 4, and using a hydraulic telescopic arm 5 to connect the walking trolley 4 to both ends of the cantilever 2, both ends of the cantilever 2 are effectively supported, and the stability of the cantilever 2 is better. The scraper 10 and the fan 11 are used to remove debris from the bottom of the bridge, and the debris dropped on the camera 9 is removed, so that the camera 9 can record the cracks on the bottom of the bridge and then detect the cracks on the bottom of the bridge 1.

[0034] Embodiment 2:

[0035] like Figure 4-5 As shown, the scraper 10 is provided with a plurality of chip grooves 12, and the arrangement direction of the chip grooves 12 is perpendicular to its moving direction. When in use, the debris scraped off by the scraper 10 falls into the discharge groove 12 and is blown out from the other side by the fan 11. The design of the chip groove 12 makes the top of the scraper 10 serrated, which is sharper and is conducive to scraping off debris at the bottom of the bridge.

[0036] By providing a plurality of chip removal grooves 12 on the scraper 10 , dust and other debris can be easily accumulated, making the scraper 10 sharper and improving the efficiency of the scraper 10 in scraping away debris.

[0037] Embodiment 3:

[0038] like Figure 1-3 and Figure 6 As shown, the walking trolley 4 includes a platform 13, which is connected to the top of the hydraulic telescopic arm 5. A first mounting frame 14 is installed on one side of the platform 13, and a U-shaped second mounting frame 15 is rotatably installed on the first mounting frame 14. A first hydraulic cylinder 16 is installed between the second mounting frame 15 and the first mounting frame 14. Three walking components are arranged on the second mounting frame 15, and the walking components include a support plate 17 arranged on the inner side of the second mounting frame 15. At least two driving wheels 18 are installed on one side of the support plate 17. The driving wheels 18 are driven by a driving motor 19. When in use, when the length of the bridge deck on both sides is not much, Figure 2 As shown, at this time, the opening of the second mounting frame 15 faces downward and is stuck on the side wall of the bridge. The driving wheel 18 located above the side wall travels on the top of the side wall to move the walking trolley 4. When more parts are exposed laterally on both sides of the bridge deck, the first hydraulic cylinder 16 is started to shorten its output shaft, thereby turning the second mounting frame 15 over. Figure 3 As shown, its opening faces the side of the bridge 1, and it is clamped on the side of the bridge 1 for use. The driving wheel 18 located above the side wall runs on the bridge deck to move the traveling trolley 4.

[0039] By providing a traveling trolley 4 including a platform 13, a first mounting frame 14, a second mounting frame 15, a first hydraulic cylinder 16 and a traveling assembly, the device can be used in two ways, neither of which occupies the bridge deck lane, does not hinder traffic, and is more convenient to use.

[0040] Embodiment 4:

[0041] like Figure 7 As shown, two second hydraulic cylinders 20 are installed on one side of the support plate 17. The second hydraulic cylinder 20 is connected to the second mounting frame 15, and its output end is connected to the support plate 17. When in use, the second hydraulic cylinder 20 is started to extend or shorten it, thereby moving the support plate 17 and adjusting the distance between the driving wheel 18 and the bridge 1 so that the driving wheel 18 is in contact with the bridge 1, thereby providing a stronger driving force for the device and facilitating the movement and stability of the device.

[0042] By installing two second hydraulic cylinders 20 on one side of the support plate 17, the distance between the driving wheel 18 and the bridge 1 can be easily adjusted, making the movement of the device more stable.

[0043] Embodiment 5:

[0044] like Figure 7 As shown, a limit block 21 is installed on the second mounting frame 15. When in use, after the second mounting frame 15 is flipped 90 degrees, its opening becomes horizontal, and the limit block 21 contacts the side of the first mounting frame 14, so that the limit block 21 cannot continue to rotate, thereby limiting the rotation angle of the second mounting frame 15.

[0045] By installing the limiting block 21 on the second mounting frame 15 , the rotation angle of the second mounting frame 15 can be conveniently limited to prevent the second mounting frame 15 from rotating too much.

[0046] Embodiment 6:

[0047] like Figure 6 As shown, a third hydraulic cylinder 23 and two guide rods 22 are installed on the platform 13. One end of the guide rod 22 passes through the platform 13 and is connected to the first mounting frame 14. The third hydraulic cylinder 23 is connected to the other end of the guide rod 22. When in use, the third hydraulic cylinder 23 is started to shorten its output shaft, thereby driving the guide rod 22 to move, so that the first mounting frame 14 moves to one side, and then adjusts the distance between the two second mounting frames 15 to adapt to the use of bridge decks with little width change.

[0048] By providing the guide rod 22 and the third hydraulic cylinder 23, the third hydraulic cylinder 23 can be used to conveniently drive the first mounting frame 14 to move laterally, thereby adjusting the distance between two second mounting frames 15 to adapt to the use of a bridge deck with a small width change.

[0049] Embodiment 7:

[0050] like Figure 6As shown, a control terminal 24 and a guardrail 25 are installed on the platform 13. The control terminal 24 is used to control the actions of the walking trolley 4, the telescopic wall 5, the first motor 6 and the detection mechanism 3. The control terminal 24 is connected to the camera 9. When in use, the operator stands in the guardrail 25 and controls the movement, detection and other actions of the device through the control terminal 24. The camera 9 displays the recorded image on the control terminal 24 in real time, which is convenient for the operator to view in real time.

[0051] By installing the control terminal 24 and the guardrail 25 on the platform 13, the device can be easily controlled and the situation under the bridge can be checked.

[0052] Working principle: When in use, two walking trolleys 4 are respectively installed on both sides of the bridge 1, and the two walking trolleys 4 and the hydraulic telescopic arm 5 are used to support the two ends of the cantilever 2 and drive it to walk. Since the two ends of the cantilever 2 are supported at the same time, the cantilever 2 is more stable, and the first motor 6 is started to drive the screw 7 to rotate, so that the support frame 8 moves horizontally on the cantilever 2. The camera 9 thereon records the bottom of the bridge and records the cracks of the entire bottom of the bridge. In addition, the hydraulic telescopic arm 5 is used to adjust the distance between the cantilever 2 and the bottom of the bridge 1 so that the scraper 10 contacts the bottom of the bridge. The scraper 10 scrapes off the moss and other debris on the bottom of the bridge, making the bottom of the bridge clean and tidy, which is convenient for the camera to record the bottom of the bridge more clearly. The fan 11 is started synchronously to blow air to the scraped bottom of the bridge to further clean the debris on the bottom of the bridge. The other fan 11 blows air towards the camera 9 to blow away the debris that falls on the camera 9 to prevent the scraped debris from covering the camera 9, so that the camera 9 can shoot clearly.
