Description

Technical Field

[0001] This utility model relates to the technical field of bridge crack detection devices, and in particular to a bridge crack detection device. Background Technology

[0002] A bridge is generally a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also come to refer to structures built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient.

[0003] Cracks often appear on the vertical concrete retaining walls on both sides of existing bridges after a long period of use. Crack detectors are usually used to detect them. However, when using a crack detector, the transducer needs to be attached to the crack. Since the vertical concrete retaining walls are quite high, it is not possible for the inspector to simply hold the transducer by hand. Using adhesive to attach the transducer is not convenient and is difficult to operate. Therefore, we provide a bridge crack detection device. Utility Model Content

[0008] In a preferred embodiment, the threaded sleeve has a rotating plate inside, the rotating plate is sleeved on the outer surface of the threaded rod, the rotating plate is fixedly connected to the threaded rod, and the rotating plate is rotatably connected to the threaded sleeve.

[0024] 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.

[0025] Example 1

[0026] like Figures 1-3As shown, this utility model provides a technical solution: a bridge crack detection device, comprising: an adjustment mechanism 1, the adjustment mechanism 1 including a bending rod 11, a threaded rod 12 sleeved inside the bending rod 11, a threaded sleeve rod 13 sleeved on the outer surface of the threaded rod 12, the threaded sleeve rod 13 being threadedly connected to the threaded rod 12, a clamping plate 14 fixedly connected to one side of the threaded sleeve rod 13, rubber pads 15 fixedly connected to the outer surfaces of both the bending rod 11 and the clamping plate 14, a threaded rod 16 sleeved inside the threaded sleeve rod 13, a threaded tube 17 sleeved on the outer surface of the threaded rod 16, the threaded tube 17 being threadedly connected to the threaded rod 16, an auxiliary mechanism 2 provided at the bottom of the threaded tube 17, the auxiliary mechanism 2 including a fixing block 21, the fixing block 21 being fixedly connected to the threaded tube 17, a limiting rod 22 fixedly connected inside the fixing block 21, a moving block 23 sleeved on the outer surface of the limiting rod 22, the moving block 23 being slidably connected to the limiting rod 22. A spring 24 is sleeved on the outer surface of the limiting rod 22. A clamping block 25 is fixedly connected to the bottom of the moving block 23. A clamping block 26 is provided on one side of the clamping block 25. The threaded sleeve 13 is sleeved inside the bent rod 11 and is slidably connected to the bent rod 11. A sliding rod 18 is fixedly connected to the outer surface of the threaded sleeve 13. A sleeve plate 19 is sleeved on the outer surface of the threaded tube 17 and the sliding rod 18. The sleeve plate 19 is fixedly connected to the threaded tube 17. The threaded rod 12 is slidably connected to the sliding rod 18. One end of the outer surface of the threaded rod 12 is fitted with a bearing 101. The bearing 101 is placed inside the bent rod 11. The bearing 101 is fixedly connected to the inner wall of the bent rod 11 and the outer surface of the threaded rod 12. The threaded sleeve 13 is provided with a rotating piece 102 inside. The rotating piece 102 is fitted onto the outer surface of the threaded rod 16. The rotating piece 102 is fixedly connected to the threaded rod 16 and rotatably connected to the threaded sleeve 13.

[0027] In this embodiment, a threaded rod 12 is provided, which can drive the threaded sleeve 13. The threaded sleeve 13 then moves the auxiliary mechanism 2 and other components, allowing the transducer placed inside the clamping block 25 and clamping block 26 to gradually approach the concrete retaining wall. A clamping plate 14 is provided, and rubber pads 15 are fixedly connected to both the clamping plate 14 and the bent rod 11. When the clamping plate 14 moves the rubber pads 15 closer to the concrete retaining wall, the rubber pads 15 are compressed, thus ensuring a more stable connection between the clamping plate 14 and the bent rod 11 and the concrete retaining wall. Furthermore, a threaded rod 16 and a threaded tube 17 are provided, with the threaded rod 16 driving the threaded tube 17. The threaded tube 17 can move up and down with the cooperation of the sliding rod 18 and the sleeve 19, ensuring a more appropriate position for the transducer and enabling the detection of the cracks that need to be inspected.

[0028] Example 2

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, the movable block 23 is sleeved inside the fixed block 21, and the movable block 23 and the fixed block 21 are slidably connected. The two ends of the spring 24 are respectively fixedly connected to the outer surface of the movable block 23 and the inner wall of the fixed block 21. The outer surface of the clamping block 26 is fixedly connected to the connecting block 27, and the outer surface of the clamping block 25 is fixedly connected to the threaded block 28. The connecting block 27 and the threaded block 28 are sleeved inside the bolt 29, which is slidably connected to the connecting block 27 and threaded block 28. The bolt 29 is threadedly connected to the threaded block 28.

[0030] In this embodiment, the auxiliary mechanism 2 is provided, which not only clamps and fixes the transducer, but also ensures that the position adjustment of the transducer is not affected by the clamping plate 14 and the rubber pad 15. The limiting rod 22 and the moving block 23 are provided, and the moving block 23 can slide on the limiting rod 22. At the same time, the moving block 23 can compress the spring 24, so that the spring 24 generates elastic force. Under the action of the elastic force of the spring 24, the clamping block 1 25 and clamping block 26 can drive the transducer to come close to the concrete retaining wall until the clamping plate 14 can no longer move. At this time, the entire detection device is in a stable state, and the position of the transducer is appropriate.

[0031] Working principle:

[0032] like Figures 1-4As shown, in use, the transducer of the crack detector can be placed inside clamping block 25 and clamping block 26, and bolt 29 can be passed through connecting block 27 and threadedly connected to threaded block 28, so that clamping block 25 and clamping block 26 are in a tight connection state. Then, the detection device is sleeved on the top of the concrete retaining wall. At this time, the bent part of the bending rod 11 and the clamping plate 14 are respectively on both sides of the concrete retaining wall. Then, the threaded rod 12 is rotated, and the threaded rod 12 can drive the threaded sleeve rod 13 with the cooperation of bearing 101. At this time, the threaded sleeve rod 13 can drive the clamping plate 14 and rubber pad 15 to gradually approach the concrete retaining wall. Then, the threaded rod 26 is rotated, and the threaded rod 26 can drive the threaded tube 17 with the cooperation of rotating plate 102. The threaded tube 17 can drive the entire auxiliary mechanism 2 to adjust its height under the guidance of sliding rod 18 and sleeve 19 until the position of the transducer is appropriate. At this time, the threaded rod 12 is rotated again, and the threaded rod 16 can drive the threaded tube 17 with the cooperation of rotating plate 102. The threaded tube 17 can drive the entire auxiliary mechanism 2 to adjust its height under the guidance of sliding rod 18 and sleeve 19 until the position of the transducer is appropriate. At this time, the threaded rod 12 is rotated again, and the threaded rod 12 is rotated again. Under the action of rod 12, clamping blocks 25 and 26 will first contact the concrete retaining wall. Then, clamping plate 14 will drive rubber pad 15 to fit against the concrete retaining wall. Clamping plate 14 will compress rubber pad 15, causing it to deform. Thus, clamping plate 14 and bending rod 11, under the action of threaded rod 12 and threaded sleeve rod 13, can tightly clamp the concrete retaining wall and keep the entire detection device stable. At the same time, as clamping plate 14 and rubber pad 15 move a small distance, clamping block 25 will act on moving block 23, causing moving block 23 to slide on limiting rod 22. Moving block 23 will simultaneously compress spring 24, causing spring 24 to generate elastic force. Then, clamping blocks 25 and 26 will drive the transducer to maintain a close fit with the concrete retaining wall. Then, the crack detector is activated. The transducer is part of the crack detector. Thus, the transducer can feed back the crack condition on the concrete retaining wall to the display of the crack detector, so that the inspectors can judge the crack condition.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
