Description

Technical Field

[0001] The invention relates to the technical field of road and bridge detection, and in particular to a crack detection device for municipal road and bridge. Background Art

[0002] Regular maintenance of roads and bridges can maintain the performance of roads. At the same time, correct technical measures can be taken to improve the quality of projects, extend the service life of roads, and postpone the time of reconstruction. Cracks will appear on the asphalt pavement. If the cracks are not repaired in time, road potholes will occur, causing deeper damage to the asphalt pavement. In the prior art, workers use handheld brushes or air guns to clean the cracks, but the above method can only clean shallow cracks. When the cracks are deep, the leaves or stones at the bottom of the cracks are not easy to clean, affecting the accuracy of the detection. Patent documents have been made to improve this.

[0003] For example, Chinese patent CN116793954A, a crack detection device for municipal road bridges, belongs to the technical field of municipal road bridge detection. Compared with the prior art, a crack detection device for municipal road bridges has an elastic detection part that can be deformed and bent to penetrate deep into the bottom of the crack for cleaning. The wrinkled layer on the elastic layer will increase the contact area with impurities, and the adhesive liquid on the wrinkled layer can adhere the impurities to the elastic layer. Then, the staff can pull the pull rope outward, and the pull rope drives the elastic layer to move into the inner tube through the fixedly connected storage block. At the same time, the elastic layer will drive the adhered impurities to move. During the movement, the impurities will gradually be wrapped and fixed by the elastic layer and extend into the inner tube, so that the staff can quickly clean the impurities at the bottom of the crack. After cleaning, the crack image can be captured by the camera, and the crack image is transmitted to the mobile terminal through the wireless module to calculate the crack data.

[0004] Although the equipment in the above document can use the elastic cladding to clean the impurities deep in the crack, it still has obvious defects in actual use, such as: Although the equipment can clean impurities deep in the cracks, in reality, most of the cracks on the road extend for a long time. If they are cleaned up manually bit by bit, it is extremely time-consuming and inefficient. Moreover, after completing the long-distance cleaning, it is still necessary to use a camera to repeatedly shoot the line, which is a cumbersome process. Therefore, a municipal road bridge crack detection device that can improve detection efficiency is now designed to solve such defects. Summary of the invention

[0015] The present invention provides a crack detection device for municipal road bridges. Compared with the existing technology, it has the following beneficial effects: (1) The crack detection device for municipal road bridges uses a protective positioning mechanism and a cleaning detection mechanism in combination. The setting of these two mechanisms can utilize the linkage between the drive and structure of the cylinder, so that the protective positioning mechanism and the cleaning detection mechanism can be locked during transportation and storage, and unlocked during use so that all equipment can be unfolded. The unfolded air pipe rack and high-pressure nozzle can be used to quickly clean the cracks with high pressure. At the same time, the crack detector can directly take pictures and detect it.

[0016] (2) The crack detection device for municipal road bridges is installed with U-shaped bending frames on both sides of the outer protective box, and the first baffle and the second baffle are installed by using the U-shaped bending frames, and are used in combination with an L-shaped plug plate and a second spring. The arrangement of these structures can allow the second spring to squeeze the concave pressure groove when the cylinder pulls the load-bearing pressure plate up, so that the first baffle and the second baffle move forward to cover the high-pressure air pump and the inclined concave frame, thereby providing daily protection for the display terminal and the high-pressure air pump. At the same time, the L-shaped plug plate is inserted into the return frame to fix the bow-shaped push frame, thereby ensuring the overall stability of the equipment during transportation and subsequent storage. When in use, the first baffle and the second baffle can be automatically opened for use by extending the cylinder, without requiring the staff to perform excessive operations, thereby facilitating use.

[0017] (3) The crack detection device for municipal road bridges is used by rotating a slewing rod on the surface of a lifting plate, and is used in combination with an arc-shaped side block, a sealed bottom cover and an arc-shaped guide plate. The arrangement of these structures enables the torsion spring compressed by the arc-shaped guide plate to utilize its elastic force to flip the sealed bottom cover to cover the bottom end of the crack detector after the lifting plate rises, thereby protecting the crack detector as a precision instrument and effectively extending its service life.

[0018] (4) The crack detection device for municipal road bridges has an undulating roller installed on the surface of two positioning vertical rods using a sliding block, and a crack detector installed on the surface of the sliding block using a lifting plate. The arrangement of these structures enables the crack detector to move up and down with the undulating roller when it moves for shooting, thereby effectively avoiding the crack detector from scratching against road debris and reducing the failure rate.

When the load-bearing pressure plate 202 descends, it will drive the two vertical guide grooves 115 to descend synchronously.

[0025] Please refer to Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10, showing the overall structure of the cleaning detection mechanism 2, the cleaning detection mechanism 2 includes a cylinder 201 and a load-bearing pressure plate 202, and the cylinder 201 is fixedly installed on the top of the outer protection box 101 through a bracket, the bottom end of the cylinder 201 passes through the outer protection box 101 and extends to the inner side of the outer protection box 101, and the load-bearing pressure plate 202 is slidably installed between the surfaces of the two vertical guide rods 117, and one end of the cylinder 201 extending to the inside of the outer protection box 101 is fixedly connected to the top of the load-bearing pressure plate 202, and the surface of the vertical guide rod 117 is fixedly connected to the top of the load-bearing pressure plate 202. A first spring 203 is sleeved on the bottom of the load-bearing pressure plate 202, and a positioning vertical rod 205 is fixedly connected to the front of both sides of the bottom of the load-bearing pressure plate 202. A sliding block 206 is slidably installed on the surface of the positioning vertical rod 205. A second spring 207 is sleeved on the surface of the positioning vertical rod 205 and located on the upper part of the sliding block 206. An undulating roller 208 is rotatably connected between the two sliding blocks 206 through a bearing member. A lifting plate 209 is fixedly connected between the surfaces of the two sliding blocks 206 through a bracket.
