Description

Technical Field

[0001] This utility model relates to the field of bridge crack monitoring technology, specifically a visual monitoring structure for bridge collapse risk cracks. Background Technology

[0002] Bridges generally refer to structures that span rivers, lakes, seas, and other bodies of water, providing convenient passage for vehicles and pedestrians. With the rapid development of the modern transportation industry, the concept of bridges has expanded to include structures built to cross mountain streams, areas with adverse geological conditions, or to meet other specific transportation needs, aiming to make travel more convenient. In the rapid process of my country's national economic construction, many large-scale infrastructure projects, especially large bridges, play a crucial role. However, under the long-term exposure to complex and variable vehicle loads, bridges are prone to structural cracks, which can lead to a gradual decrease in their structural resistance and, in extreme cases, even catastrophic accidents.

[0003] Currently available visual monitoring structures for bridge collapse risk cracks are typically fixed at a specific point for monitoring, resulting in a limited monitoring range. Furthermore, when the equipment needs to be installed, maintained, or repaired, operators must use tools to climb to higher locations, which is complex, inefficient, and poses safety risks. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a visual monitoring structure for bridge collapse risk cracks, so as to solve the technical problems of limited monitoring range, complex and inefficient equipment installation and maintenance, and safety risks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a visual monitoring structure for bridge collapse risk cracks, comprising a guide rail and a monitoring component. The monitoring component includes a monitoring mechanism and a mounting mechanism. The monitoring mechanism includes a slider, a base plate fixedly connected to the bottom of the slider, rollers rotatably connected to the top two sides of the base plate, a charging interface provided on the outer surface of the slider, a top plate fixedly connected to the top of the slider, a mounting block fixedly connected to the top of the top plate, a turntable rotatably connected to the top of the mounting block, a monitoring instrument connected to the top of the turntable via a rotating rod, and a transparent protective shell provided on the rotating rod.

[0006] By adopting the above technical solution, the transparent protective shell protects the monitor from interference and damage from the external environment, while not affecting the normal operation of the monitor, improving the durability and reliability of the monitoring structure, and increasing the service life of the equipment.

[0007] Furthermore, two rollers are symmetrically arranged along the central axis of the slider, and the slider, bottom plate, and top plate form an I-shaped structure.

[0008] By adopting the above technical solution, two rollers are symmetrically arranged along the central axis of the slider, which makes the monitoring component move more smoothly on the guide rail and maintains the balance of the monitoring component during the movement.

[0009] Furthermore, the mounting mechanism includes a rotating block, and a threaded rod is fixedly connected to one side of the rotating block.

[0010] By adopting the above technical solution, rotating the rotating block can drive the threaded rod fixedly connected to it to rotate together, thereby realizing the extension or retraction of the mounting rod, making the installation and recycling of the equipment more convenient.

[0011] Furthermore, one end of the threaded rod is threadedly connected to a mounting rod, and a second groove is provided on the outer surface of the top plate for the mounting rod to slide.

[0012] By adopting the above technical solution, one end of the threaded rod is connected to the mounting rod by a thread, which allows the mounting rod to be easily extended or retracted.

[0013] Furthermore, there are two mounting rods mirrored along the central axis of the slider, and the mounting rods are made of aluminum alloy.

[0014] By adopting the above technical solution, two mounting rods are mirror-set along the central axis of the slider, which makes the monitoring component more stable when mounted. The two mounting rods can share the weight of the monitoring component, disperse the stress points, reduce the risk of single-point stress, improve the stability of the overall structure, and avoid tilting or overturning due to unstable center of gravity.

[0015] Furthermore, the guide rail has a first groove inside, which is adapted to the slider.

[0016] By adopting the above technical solution, the first groove inside the guide rail is adapted to the shape and size of the slider, ensuring that the slider can slide smoothly and accurately on the guide rail, thereby improving the stability of the monitoring component during movement.

[0017] In summary, the present invention has the following main advantages:

[0018] 1. This utility model, by setting up a mounting mechanism, with the rotating block, threaded rod and mounting rod cooperating, enables the monitoring component to cooperate with an external drone. During installation, the drone can transport the monitoring component to the guide rail, and the mounting rod and rotating block cooperate to install and detach the monitoring component on the guide rail. During inspection or maintenance, the rotation of the rotating block and threaded rod causes the mounting rod to extend and overlap the mounting frame at the bottom of the drone, so that the equipment can be driven off the track by the drone, which improves the installation and maintenance efficiency of the equipment and reduces the risk and difficulty of manual operation.

[0019] 2. By setting up a monitoring mechanism, the slider and guide rail allow the equipment to slide freely along the guide rail, increasing the movement and monitoring range of the monitor and improving the applicability of the equipment. At the same time, it avoids the need for operators to install and fix the equipment at fixed points, increasing the convenience and flexibility of the equipment. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] A visual monitoring structure for bridge collapse risk cracks, such as Figures 1-4As shown, the device includes a guide rail 1 and a monitoring component 3. The monitoring component 3 includes a monitoring mechanism 4 and a mounting mechanism 5. The monitoring mechanism 4 includes a slider 401. A base plate 402 is fixedly connected to the bottom of the slider 401. Rollers 404 are rotatably connected to the top two sides of the base plate 402. A charging interface 403 is provided on the outer surface of the slider 401. A top plate 410 is fixedly connected to the top of the slider 401. A mounting block 405 is fixedly connected to the top of the top plate 410. A turntable 406 is rotatably connected to the top of the mounting block 405. A monitoring instrument 408 is connected to the top of the turntable 406 via a rotating rod 407. A transparent protective shell 409 is provided on the rotating rod 407. The transparent protective shell 409 protects the monitoring instrument 408 from interference and damage from the external environment, while not affecting the normal operation of the monitoring instrument 408. This improves the durability and reliability of the monitoring structure and increases the service life of the equipment. The charging interface 403 facilitates the charging and maintenance of the monitoring mechanism 4. Charging can be performed without disassembling the entire monitoring component 3, improving the ease of use.

[0027] See Figure 1 , Figure 2 , Figure 3 Two rollers 404 are symmetrically arranged along the central axis of slider 401. Slider 401, base plate 402 and top plate 410 form an I-shaped structure. The symmetrical arrangement of two rollers 404 along the central axis of slider 401 makes the monitoring component 3 move more smoothly on the guide rail 1 and maintains the balance of the monitoring component 3 during the movement. Slider 401, as the middle part of the I-shaped structure, is adapted to the first slide groove 2 of the guide rail 1, realizing the smooth movement of the monitoring component 3 on the guide rail 1, while preventing the equipment from falling off the guide rail 1.

[0028] See Figure 1 , Figure 2 , Figure 4 The mounting mechanism 5 includes a rotating block 501. A threaded rod 502 is fixedly connected to one side of the rotating block 501. By rotating the rotating block 501, the threaded rod 502 fixedly connected to it can be rotated together, thereby realizing the extension or retraction of the mounting rod 503, making the installation and retrieval of the equipment more convenient. One side of the threaded rod 502 is fixedly connected to the rotating block 501, so that the threaded rod 502 can stably transmit the rotational force of the rotating block 501.

[0029] See Figure 4One end of the threaded rod 502 is threadedly connected to the mounting rod 503. The outer surface of the top plate 410 is provided with a second sliding groove 504 for the mounting rod 503 to slide. The connection method allows the mounting rod 503 to extend or retract easily. The second sliding groove 504 on the outer surface of the top plate 410 provides the necessary space for the sliding of the mounting rod 503, so that the mounting rod 503 can maintain linear motion during extension or retraction, avoiding deviation or shaking and improving the stability of the equipment.

[0030] See Figure 1 , Figure 4 Two mounting rods 503 are mirror-image arranged along the central axis of the slider 401, and the mounting rods 503 are made of aluminum alloy. The mirror-image arrangement of the two mounting rods 503 along the central axis of the slider 401 makes the monitoring component 3 more stable when mounted. The two mounting rods 503 can share the weight of the monitoring component 3, distributing the stress points, reducing the risk of single-point stress, improving the stability of the overall structure, and avoiding tilting or tipping due to unstable center of gravity. The mounting rods 503 are made of aluminum alloy, which has low density, high strength, and good corrosion resistance. This allows the mounting rods 503 to maintain sufficient strength while reducing the overall weight, making it easier to mount and transport the UAV.

[0031] See Figure 1 , Figure 3 The guide rail 1 has a first groove 2 inside, which is adapted to the slider 401. The shape and size of the first groove 2 inside the guide rail 1 are adapted to the slider 401, which ensures that the slider 401 can slide smoothly and accurately on the guide rail 1, improving the stability of the monitoring component 3 during movement. The cooperation between the guide rail 1 and the slider 401 simplifies the installation process of the monitoring component 3. The monitoring component 3 can be fixed on the guide rail 1 simply by inserting the slider 401 into the first groove 2, which facilitates the maintenance and replacement of the monitoring component 3.

[0032] The implementation principle of this utility model is as follows: First, the operator rotates the rotating block 501 so that the two mounting rods 503 extend and overlap the mounting frame at the bottom of the external drone. Then, the drone transports the rods to the guide rail 1, and the slider 401 enters the first slide groove 2. Then, the internal motor drives the roller 404 to rotate, causing the slider 401 to slide along the guide rail 1. When the slider 401 moves, the rotating block 501 rubs against the guide rail 1, causing the rotating block 501 to rotate and drive the threaded rod 502 to rotate, so that the mounting rod 503 slides along the second slide groove 504 and retracts into the top plate 41. Within 0, the device detaches from the drone. Then, the monitor 408 moves to the monitoring position with the slider 401. The internal motor drives the turntable 406 to rotate, causing the rotating rod 407 to drive the monitor 408 to rotate for fine adjustment. When maintenance or repair is required, the drone is stopped at the predetermined position. Then, the internal motor drives the slider 401 to move in the opposite direction, causing the rotating block 501 to rotate in the opposite direction. This causes the two mounting rods 503 to extend and attach to the mounting frame at the bottom of the drone. Then, the drone drives the device off the track and retracts it.
