Description

Technical Field

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

[0002] Bridge crack acquisition devices belong to the field of bridge inspection technology. Their core function is to accurately collect cracks on the bridge surface, providing crucial data for bridge safety assessment and maintenance. During long-term use, bridges are prone to developing various cracks due to factors such as vehicle traffic and natural environmental erosion. If these cracks are not detected and addressed in a timely manner, they can lead to serious safety hazards. Therefore, efficient and flexible crack acquisition devices are particularly important.

[0003] A search revealed Chinese patent CN220538353U, which discloses a road and bridge subgrade crack detection device. The device includes a base with a power storage device fixedly connected to it. A housing is fixedly connected to one end of the base, and a cover plate is fixedly connected to the upper end of the housing. A telescopic connecting rod is mounted on the upper end of the base, and a control panel is fitted onto the telescopic connecting rod. An electric telescopic rod is fixedly connected to the lower end of the base, and an ultrasonic detection probe is fixedly connected to the electric telescopic rod. A scanning probe is also fixedly connected to the lower end of the base. A caster wheel is fixedly connected to the lower end of the base, and a cleaning structure is provided at the lower end of the base. During the detection process, when encountering scattered stones or gravel on the subgrade surface, the cleaning structure at the end of the base can be activated using the control panel to clean the road surface before the scanning probe detects the subgrade. This reduces the detection difficulty caused by scattered stones and gravel, making it more convenient to use.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] Current bridge crack detection devices have significant limitations. Some devices use specialized handcarts as carriers, which can only be pushed and used on flat areas such as bridge decks, making them unsuitable for complex road conditions and limiting their range of movement. Other devices, while compatible with vehicles, have fixed installation structures that only fit specific vehicle models and cannot be flexibly installed on common carriers such as car trunks or pickup truck beds.

[0006] The root of this problem lies in the lack of universality in the installation structure design of existing devices: their mounting brackets are mostly fixed structures matched to specific vehicle models, lacking flexible adjustable limits and fixing components, and cannot be adapted to the size and shape of the trunk or cargo box of different vehicle models. This design requires users to equip themselves with special vehicles, increasing usage costs and limiting the widespread adoption and application scenarios of the device. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model proposes a bridge crack acquisition device. Through a U-shaped mounting bracket and a first fixing component, it enables flexible installation in the trunk of any car or pickup truck. The U-shaped limiting clamp can adapt to the opening structure of different vehicle trunks or cargo boxes. The first fixing component, consisting of a threaded tube, a second bolt, and a clamping plate, allows for adjustment of the clamping plate's position by rotating the second bolt, thus securely clamping the edges of trunks or cargo boxes of different sizes. This solves the problem that existing devices can only be adapted to specific vehicle models and require additional specialized vehicles.

[0008] The technical solution to achieve the purpose of this utility model is: a bridge crack acquisition device, including an inspection vehicle body with a rear compartment, and an image acquisition device, and also includes;

[0009] Two sets of U-shaped mounting brackets are installed at the upper opening of the rear compartment of the inspection vehicle body. The mounting brackets include:

[0010] The system includes two sets of limiting clamps and a first fixing component. The first fixing component is located on the back of the two sets of limiting clamps, and a control box is located on the front side of the two sets of limiting clamps. The limiting clamps are threadedly fixed to the rear compartment of the control box by the first component.

[0011] Furthermore, a lateral adjustment mechanism is provided between the two sets of limiting clamps to control the horizontal distance between the box body and the two sets of limiting clamps.

[0012] A graphic acquisition device, wherein the graphic acquisition device is disposed at the bottom of the control box;

[0013] The image acquisition device includes a detection platform with third detection probes connected to both ends. A V-shaped detection groove is provided at the bottom of the detection platform. A row of first detection probes is arranged vertically downward at the bottom of the inner side of the detection groove, and a row of inclined second detection probes is arranged on the other side of the inner side of the detection groove.

[0014] In some embodiments, the first fixing component includes a threaded tube that laterally connects the inner and outer sides of the limiting clamp, a second bolt is threaded onto the threaded tube, and the second bolt extends to one side inside the limiting clamp and is connected to a clamping plate.

[0015] In some embodiments, the lateral adjustment mechanism includes a mating block installed on the other side outside the limiting clamp, with a threaded hole between the two mating blocks, and a first bolt extending into the threaded hole threaded to the top of each mating block, and horizontal bars passing through the threaded holes on the limiting clamp are laterally connected to both sides of the control box.

[0016] In some embodiments, the control box is provided with a telescopic rod for controlling the raising and lowering of the graphic acquisition device, and the bottom output end of the telescopic rod is connected to the top surface of the detection table.

[0017] In some embodiments, each of the clamping plates is a resilient rubber disc.

[0018] In some embodiments, the limiting clamp and the testing table are made of stainless steel.

[0019] Compared with existing technologies, the significant advantages of this invention are:

[0020] Firstly, this utility model, through a U-shaped mounting bracket and a first fixing component, enables flexible installation in the trunk of any car or pickup truck. The U-shaped limiting clamp can adapt to the opening structure of different car trunks or cargo boxes. The first fixing component, consisting of a threaded tube, a second bolt, and a clamping plate, allows the position of the clamping plate to be adjusted by rotating the second bolt, thereby securely clamping the edges of trunks or cargo boxes of different sizes. This solves the problem that existing devices can only be adapted to specific car models and require additional specialized vehicles.

[0021] Secondly, this utility model utilizes a lateral adjustment mechanism and a telescopic rod to flexibly adjust the horizontal position and height of the graphic acquisition device. The lateral adjustment mechanism, through the movement of the crossbar within the threaded hole and the fixing of the first bolt, can change the horizontal distance between the control box and the limiting clamp; the telescopic rod can drive the detection platform to rise and fall, ensuring that the detection probe adapts to the detection needs of different locations on the bridge, thus improving the flexibility of the detection.

[0022] Thirdly, the graphic acquisition device of this utility model adopts a multi-probe collaborative design. The first and second detection probes in the V-shaped detection groove cooperate with the third detection probes at both ends of the detection platform to collect cracks in the bridge from different angles and positions in all directions, avoiding detection omissions and improving the comprehensiveness and accuracy of crack acquisition.

[0030] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0031] This utility model provides an improved bridge crack detection device. The technical solution of this utility model is as follows:

[0032] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0033] like Figure 1 - Figure 4 As shown, the bridge crack acquisition device includes a detection vehicle body 600 with a rear compartment, two sets of U-shaped mounting brackets, a first fixing component, a lateral adjustment mechanism, a control box 100, and an image acquisition device. The mounting brackets are located at the upper opening of the rear compartment of the detection vehicle body 600. Each mounting bracket includes two sets of limiting clamps 200 and a first fixing component. The first fixing component is located on the back of the two sets of limiting clamps 200, and the control box 100 is located on the front side of the two sets of limiting clamps 200. The limiting clamps 200 are threadedly fixed to the rear compartment of the control box 100 by the first fixing component. Furthermore, a lateral adjustment mechanism is provided between the two sets of limiting clamps 200 to control the horizontal distance between the control box 100 and the two sets of limiting clamps 200. The graphic acquisition device is located at the bottom of the control box 100. The graphic acquisition device includes a detection platform 300. The two ends of the detection platform 300 are connected to third detection probes 500. A V-shaped detection groove 301 is opened at the bottom of the detection platform 300. A row of first detection probes 400 is arranged vertically downward at the bottom of the inner side of the detection groove 301. A row of inclined second detection probes 401 is arranged on the other side of the inner side of the detection groove 301.

[0034] In one embodiment, two sets of U-shaped mounting brackets are installed at the upper opening of the rear compartment of the inspection vehicle body 600 via a first fixing component, and a lateral adjustment mechanism is provided between the two sets of limiting clamps 200. Through the U-shaped mounting brackets, the first fixing component, and the lateral adjustment mechanism, the device is stably installed and flexibly adjusted, enabling the control box 100 to adjust the horizontal distance between itself and the limiting clamps 200 according to actual inspection needs, thereby adapting to the inspection needs of bridge structures of different widths and improving the versatility of the device.

[0035] like Figure 1 - Figure 4 As shown, in one embodiment, the image acquisition device is located at the bottom of the control box 100. It includes a detection platform 300, with third detection probes 500 connected to both ends of the detection platform 300. A V-shaped detection groove 301 is formed at the bottom of the detection platform 300. A row of first detection probes 400 is arranged vertically downward at the bottom inner side of the detection groove 301, and a row of inclined second detection probes 401 is arranged on the other side of the detection groove 301. With this arrangement, the V-shaped detection groove 301 can better fit the edge and other structures of the bridge. The first detection probes 400 can accurately collect vertical cracks on the bridge surface, while the inclined second detection probes 401 can detect cracks on the sides and in the inclined direction. The third detection probes 500 at both ends of the detection platform 300 can supplement the detection of areas outside the sides of the detection groove 301. The three work together to achieve all-round collection of cracks at different locations and angles on the bridge, avoiding the omission of cracks and improving the comprehensiveness and accuracy of the detection.

[0036] like Figure 2 As shown, in one embodiment, the first fixing component includes a threaded tube 700 that connects the inner and outer sides of the limiting clamp 200 laterally. A second bolt 701 is threaded onto the threaded tube 700. The second bolt 701 extends to one side of the limiting clamp 200 and is connected to a clamping plate 702. By rotating the second bolt 701, the clamping plate 702 can be moved inside the limiting clamp 200, thereby clamping or releasing the opening of the rear compartment of the control box 100. This allows the limiting clamp 200 to be detachably installed on the rear compartment of the detection vehicle body 600. This detachable connection method not only facilitates the installation and disassembly of the device and makes it easier for later maintenance and replacement, but also makes the device applicable to different types of trucks or car trunks, enhancing the applicability of the device.

[0037] like Figure 1 and Figure 3As shown, in one embodiment, the lateral adjustment mechanism includes a docking block 201 installed on the other side of the limit clamp 200. A threaded hole is provided between the two docking blocks 201. A first bolt 202 extending into the threaded hole is threadedly connected to the top of each docking block 201. A crossbar 101 passing through the threaded hole on the limit clamp 200 is laterally connected to both sides of the control box 100. When it is necessary to adjust the horizontal distance between the control box 100 and the two sets of limit clamps 200, simply loosen the first bolt 202 so that the crossbar 101 can move freely in the threaded hole. After adjusting to the appropriate position, tighten the first bolt 202 to fix the crossbar 101. The horizontal distance can be adjusted. The operation is simple and convenient and can quickly adapt to different detection range requirements.

[0038] like Figure 1 and Figure 3 As shown, in one embodiment, the control box 100 is provided with a telescopic rod 102 for controlling the lifting and lowering of the graphic acquisition device. The bottom output end of the telescopic rod 102 is connected to the top surface of the detection platform 300. By extending and retracting the telescopic rod 102, the detection platform 300 can be moved up and down, thereby adjusting the height of the graphic acquisition device so that it can adapt to the crack detection at different heights of the bridge. Whether it is a high or low point of the bridge, it can ensure that the detection probe is at the optimal detection height, further improving the flexibility and accuracy of the detection.

[0039] In one embodiment, each clamping plate 702 is made of elastic rubber disc. Due to the good elasticity and friction of rubber, when the clamping plate 702 contacts the rear compartment of the inspection vehicle body 600, the rubber disc can better fit the contact surface, increase the friction, and make the fixing of the limiting clamping plate 200 more stable. At the same time, the rubber material can also play a buffering role, reducing the damage to the inspection vehicle body 600 caused by vibration during the movement of the device.

[0040] In one embodiment, the limiting clamp 200 and the testing table 300 are made of stainless steel. Stainless steel has high strength and good corrosion resistance, and can withstand various external forces during the testing process. At the same time, in the complex outdoor environment where bridge testing is conducted, it is not easily corroded by rainwater, moisture, etc., which effectively extends the service life of the device and reduces maintenance costs.

[0041] Working principle and usage process of this utility model:

[0042] Working Principle: This bridge crack acquisition device detects bridge cracks using an image acquisition device mounted on the inspection vehicle body 600. Different detection probes in the image acquisition device capture images of the bridge surface from different angles and positions. The acquired image information is transmitted to the control box 100 for processing and analysis, thereby enabling the identification and recording of bridge cracks. The lateral adjustment mechanism and the telescopic rod 102 are used to adjust the horizontal position and height of the image acquisition device, respectively, to ensure that the detection probes are accurately aligned with the inspection area. The first fixing component ensures the stable installation of the entire device on the inspection vehicle body 600, ensuring the stability of the inspection process.

[0043] Usage process:

[0044] Installation device: Place two sets of U-shaped limiting clamps 200 at the upper opening of the rear compartment of the inspection vehicle body 600 and fix them by the first fixing component. Rotate the second bolt 701 to make the clamping plate 702 tightly clamp the edge of the rear compartment, and firmly install the limiting clamps 200 on the inspection vehicle.

[0045] Adjusting the lateral spacing: Based on the bridge width and inspection requirements, adjust the horizontal spacing between the control box 100 and the two sets of limiting clamps 200. Loosen the first bolt 202 on the connecting block 201, push the control box 100, and move the crossbar 101 within the threaded hole of the limiting clamp 200. Once the appropriate spacing is achieved, tighten the first bolt 202 to fix the crossbar 101, thus completing the adjustment of the horizontal spacing.

[0046] Install the graphic acquisition device: Install the graphic acquisition device at the bottom of the control box 100, and ensure that the third detection probe 500 at both ends of the detection table 300, the first detection probe 400 and the second detection probe 401 in the detection slot 301 are firmly installed and can work normally.

[0047] Adjusting the detection height: Based on the height of the part of the bridge that needs to be detected, adjust the height of the detection platform 300 by controlling the telescopic rod 102 on the control box 100. Activate the telescopic rod 102 to extend or retract it, causing the detection platform 300 to rise or fall until the detection probe is at a suitable detection height, and then stop the telescopic rod 102.

[0048] Crack acquisition: The inspection vehicle 600 slowly moves along the bridge. During the journey, the image acquisition device begins to operate. The first detection probe 400 vertically downwards acquires images of cracks on the bridge surface in the vertical direction. The second detection probe 401 is tilted to acquire images of cracks on the sides and in the tilt direction. The third detection probe 500 supplements the acquisition of images of areas outside the two sides of the detection groove 301. All acquired image information is transmitted to the control box 100 in real time.

[0049] End of Inspection: After the bridge inspection is completed, turn off the graphic acquisition device and drive the inspection vehicle 600 away from the inspection site. If disassembly is required, first loosen the second bolt 701 of the first fixing component to release the clamping plate 702 from clamping the edge of the rear compartment, and then remove the limiting clamping plate 200 from the inspection vehicle to complete the entire inspection process.

[0050] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
