Description

Technical Field

[0001] This utility model relates to the field of bridge inspection technology, and in particular to a handheld long-distance inspection device for the appearance of bearings. Background Technology

[0002] Currently, the surface inspection of bridge bearings mainly relies on the following technical means: 1. Visual inspection: This is the traditional inspection method. Inspectors usually use bridge inspection vehicles, aerial work platforms, or directly on the bridge deck to visually observe the surface condition of the bearings and determine whether there are defects such as cracks, deformation, aging, and corrosion. The advantage of visual inspection is that it is intuitive and simple, but its limitations are also very obvious. First, the inspection results are highly dependent on the experience and subjective judgment of the inspectors, which is prone to bias. Second, due to the limited line of sight and accessibility of the inspectors, visual inspection is difficult to effectively cover bearings on high piers, long-span bridges, or those that are difficult to access, resulting in blind spots. In addition, the effectiveness of visual inspection will be further reduced in environments with poor lighting conditions, such as at the bottom of the bridge. 2. Camera photography: In order to overcome the accessibility shortcomings of visual inspection, existing technologies have also attempted to use camera photography for bearing inspection. A common method is to use drones equipped with cameras to photograph the bearings at the bottom of the bridge. Drone technology has the advantages of flexibility and mobility, and can reach areas that are difficult for humans to access. However, drones are complex to operate, requiring professional personnel and posing certain safety risks, such as crashes. Furthermore, drones have limited battery life, making it difficult to support long-duration, large-scale inspection work. Another approach is to use a long pole connected to a mobile phone or ordinary camera for shooting. While this method is relatively convenient, the focusing and zoom capabilities of mobile phones or ordinary cameras are limited when shooting at long distances, making it difficult to obtain clear images, especially for capturing sub-centimeter-level micro-cracks or damage. In addition, the length of the telescopic pole is also limited; for high pier supports, the long pole connection method is also difficult to reach. 3. Bridge inspection vehicle-assisted inspection: For bridges spanning rivers, seas, or railway lines, bridge inspection vehicles are commonly used inspection platforms. Bridge inspection vehicles can provide a stable working platform for inspectors and carry various inspection equipment. However, bridge inspection vehicle equipment is expensive, resulting in high operating costs, and road closures during construction can severely impact traffic, especially in busy areas. Furthermore, the use of bridge inspection vehicles is subject to many restrictions, or even impossible, on complex bridge structures, such as combined road and rail bridges. At the same time, operating bridge inspection vehicles also poses certain safety hazards. 4. Non-destructive testing (limitations for surface inspection): Non-destructive testing techniques, such as ultrasonic and radiographic testing, are mainly used to detect internal defects in bearings. Although they can also be used for surface inspection, their operation is complex, costly, and inefficient, and they are generally not suitable for routine, large-scale surface inspection of bearings. Non-destructive testing techniques are more suitable for detailed inspection and evaluation of suspected defects.

[0003] However, the existing technologies mentioned above have the following main shortcomings in the long-distance inspection of bridge bearing appearance: 1. Insufficient long-distance imaging capability and difficulty in guaranteeing image quality: Whether using a long pole connected to a mobile phone or a drone equipped with a regular camera, it is difficult to obtain high-definition images of bearing appearance defects under long-distance conditions, especially with limited ability to identify defects such as fine cracks. 2. Blind spots in the inspection of high pier bearings: The limited length of existing telescopic poles, the complexity and high risk of drone operation, and the limited use of bridge inspection vehicles result in blind spots in the inspection of high pier bearings, making it difficult to comprehensively assess the health status of the bearings. 3. Insufficient inspection efficiency and convenience: Visual inspection is inefficient and highly subjective; drone operation is complex and requires a long preparation time; bridge inspection vehicles have poor mobility and obstruct traffic during construction, all of which contribute to the insufficient inspection efficiency and convenience of existing technologies. 4. High inspection costs: Bridge inspection vehicles are expensive, resulting in high operating costs; drone operation requires professional personnel, which also increases inspection costs. 5. Potential safety hazards: High-altitude operations, drone operation, and bridge inspection vehicle construction all pose certain safety risks. Utility Model Content

[0044] like Figures 1 to 5 As shown, this embodiment of a handheld support appearance long-distance inspection device mainly includes a telescopic rod 1, a remotely controllable zoom camera 2, a controllable rotating pan-tilt head 3, and a clamping connector 4. The telescopic rod 1 serves as the main support and extension mechanism of the entire device, possessing telescopic characteristics and adjustable length according to actual inspection needs, thereby enabling access to supports at different heights and distances. The handheld end of the telescopic rod is for the inspector to grip, ensuring stable operation of the device. The remotely controllable zoom camera 2 is the core imaging component of the device, mounted on the controllable rotating pan-tilt head 3, allowing the camera to flexibly adjust its shooting angle using the rotating pan-tilt head. Furthermore, both the camera and the rotating pan-tilt head are remotely controllable, allowing the inspector to precisely control the camera's zoom, focus, photo taking, and video recording functions, as well as the rotation of the pan-tilt head, through remote control methods such as a mobile app, thereby completing operations from a safe location away from the inspection target. The camera's own zoom lens ensures that high-definition images of support appearance defects can still be obtained under long-distance conditions. The controllable rotating pan-tilt head 3 serves two purposes: firstly, it supports the remotely controlled zoom camera 2, providing it with a stable support platform; secondly, through its own rotational drive, the pan-tilt head 3 allows for angle adjustments in both horizontal and vertical directions, enabling omnidirectional observation of the support. The clamping connector 4 serves as the connecting structure between the rotating pan-tilt head 3 and the telescopic rod 1, and its structure is divided into a connecting part and a clamping part. The connecting part securely connects to the controllable rotating pan-tilt head 3, using bolts, nuts, or other fastening methods to ensure that the pan-tilt head and camera are reliably fixed to the clamping connector. The clamping part secures the clamping connector 4 to the telescopic end of the telescopic rod 1. This clamping connection method allows the entire camera system to be firmly installed at the front end of the telescopic rod and to withstand various forces generated during operation.

[0045] During the inspection process, the inspectors first adjust the length of the telescopic rod 1 according to the distance and height of the support to be inspected. Holding the telescopic rod, they extend the clamping connector 4, which carries a remotely controlled zoom camera 2 and a controllable rotating gimbal 3, towards the support to be inspected. Subsequently, through a remote control terminal, they operate the controllable rotating gimbal 3 to adjust the shooting angle of the camera 2 and use the zoom and focus functions of the camera 2 to obtain clear images of the apparent defects of the support. The captured images can be transmitted back to the control terminal in real time for the inspectors to observe and record. Therefore, the structural solution of this embodiment can help solve the technical problems of poor image quality from long-distance shooting, limited inspection of high pier supports, complex and risky operation of drones, insufficient battery life, high cost of bridge inspection vehicles, road occupation during construction, and poor safety.

[0046] In one embodiment, the connecting part and clamping part of the clamping connector 4 are respectively configured as a gimbal fixing plate 5 and a fixing clamp. The gimbal fixing plate 5 and the fixing clamp are fixedly connected to each other, forming an integral structure. The controllable rotating gimbal 3 is connected to the gimbal fixing plate 5, which serves as the mounting base for the controllable rotating gimbal 3. The fixing clamp is clamped to the telescopic end of the telescopic rod 1. The design of the fixing clamp is intended to form a stable clamping fit with the telescopic end of the telescopic rod 1, thereby fixing the entire testing equipment to the front end of the telescopic rod 1.

[0047] It is understandable that by refining the clamping connector 4 into a gimbal fixing plate 5 and a fixing clamp, a clear division of functions is achieved. The gimbal fixing plate 5 is specifically used to connect and fix the controllable rotating gimbal 3, providing a stable rotation platform for the camera; the fixing clamp focuses on clamping the telescopic rod 1, ensuring the overall stability of the equipment. This refined structural design makes the functions of the components clearer and the structure more reasonable, which is conducive to the assembly and stable operation of the equipment. At the same time, the use of a fixed connection to combine the gimbal fixing plate 5 and the fixing clamp ensures the overall strength and stability of the clamping connector 4, providing reliable support for the camera and rotating gimbal mounted on it, preventing loosening or falling off during use, and improving the reliability and safety of the testing equipment.

[0048] In one embodiment, the clamping connector 4 is provided with a battery box 6 for accommodating batteries, and the battery box 6 is fixedly connected to the fixing clamp. The battery box 6, as a component of the clamping connector 4, forms an integrated structure with the fixing clamp. The function of the battery box 6 is to accommodate batteries and provide power to the remote-controlled zoom camera 2. Battery wires pass through the battery box 6 and are electrically connected to the power interface of the remote-controlled zoom camera 2, realizing efficient power transmission from the battery box 6 to the camera 2 and ensuring the normal operation of the camera 2.

[0049] It is understandable that integrating the battery box 6 into the clamping connector 4 enables localized power configuration, eliminating the need for external power cables and improving the portability and operational flexibility of the device. Fixing the battery box 6 securely to the clamp ensures its stability, preventing the battery from shaking or falling out during use and improving power supply reliability. The battery wires extend from the battery box 6 and connect directly to the camera 2, enabling direct power supply, simplifying circuit connections, reducing the likelihood of malfunctions, and enhancing the device's integration and compactness. This integrated power solution makes the device more independent and easier to use, especially suitable for bridge inspection scenarios in the field or without external power.

[0050] In one embodiment, the fixing clamp consists of at least two X-shaped plates 7, which are arranged in a straight line relative to each other. Each X-shaped plate 7 has four connecting end plates 71 integrally formed on its four ends. The gimbal fixing plate 5 and the battery box 6 are respectively distributed on opposite sides of the fixing clamp. One end of the X-shaped plate 7 of the fixing clamp is connected to the gimbal fixing plate 5 via two overlapping connecting end plates 71 on one side, and the other end of the X-shaped plate 7 of the fixing clamp is connected to the outer shell of the battery box 6 via two overlapping connecting end plates 71 on one side. A clamping opening 72 is formed between two adjacent X-shaped plates 7 for clamping the telescopic end of the telescopic rod 1. Bolt assemblies 8 are detachably provided on opposite sides of the clamping opening 72. Each bolt assembly 8 is threadedly connected to the connecting end plates 71 on two adjacent X-shaped plates 7. By tightening the bolt assemblies 8, the connecting end plates 71 are fixedly connected, thereby locking the clamping opening 72.

[0051] It is understandable that the X-shaped plate 7 is used as the main structure of the fixing clamp. Utilizing the mechanical properties of the X-shape, a more stable clamping force can be generated under the action of the bolt assembly 8, ensuring the stability of the connection between the fixing clamp and the telescopic rod 1 and preventing slippage or detachment during use. The one-piece molding design of the connecting end plate 71 enhances the structural strength of the X-shaped plate 7 and provides a reliable connection surface for the bolt connection. The connecting end plate 71 of adjacent X-shaped plates 7 is detachably connected via the bolt assembly 8, enabling adjustable opening and closing of the clamping port 72. This facilitates the installation and removal of the telescopic rod 1 and allows adjustment of the clamping force according to the diameter of the telescopic rod 1, improving the versatility and adaptability of the equipment. The gimbal fixing plate 5 and the battery box 6 are respectively connected to the X-shaped plates 7 on both sides of the fixing clamp, making the entire clamping connector 4 compact and rationally laid out.

[0052] In one embodiment, a rubber pad is provided on the inner side of the clamping opening 72, and the rubber pad contacts the outer surface of the telescopic rod 1. It is understood that the use of the rubber pad significantly increases the coefficient of friction between the clamping opening 72 and the telescopic rod 1, enhancing clamping stability and effectively preventing the telescopic rod 1 from sliding within the clamping opening 72, especially when the equipment is tilted or under force, maintaining a stable clamping state. Simultaneously, the rubber pad is elastic, which can buffer the clamping force, protecting the outer surface of the telescopic rod 1 from direct friction and pressure from the hard clamping opening 72, preventing scratches or damage to the surface of the telescopic rod 1, extending the service life of the telescopic rod 1, and ensuring the reliability and durability of the clamping connection.

[0053] In one embodiment, the gimbal mounting plate 5 and the controllable rotating gimbal 3 are detachably fixed to each other by bolts. This detachable bolt connection allows the controllable rotating gimbal 3 to be easily installed onto and removed from the gimbal mounting plate 5. This detachability simplifies the assembly process and improves assembly efficiency. Furthermore, when the controllable rotating gimbal 3 requires maintenance, repair, or replacement, it can be easily disassembled for operation without replacing the entire clamping connector 4, reducing maintenance costs and extending the equipment's lifespan. In addition, the detachable connection also enables modular design of the equipment, allowing users to easily replace different models or functions of the rotating gimbal as needed.

[0054] In one embodiment, the battery compartment 6 is equipped with cable ties for securing the batteries. Using cable ties to secure batteries is a simple, quick, and effective method. The cable ties firmly bind the batteries within the battery compartment 6, preventing them from shaking or shifting when the device is moved or vibrated, ensuring stable contact between the batteries and the battery compartment 6, avoiding poor power contact or power outages caused by battery movement, and improving power supply reliability. Cable ties are inexpensive to use, easy to operate, and easy to replace, facilitating battery installation and replacement for users.

[0055] In one embodiment, the remotely controllable zoom camera 2 incorporates a zoom lens and a starlight-level image sensor. The zoom lens provides the camera 2 with optical zoom capabilities, allowing for changes in shooting angle and magnification. The starlight-level image sensor enhances the camera 2's imaging performance in low-light environments. The zoom lens enables the camera 2 to perform optical zoom, allowing for magnified image details during long-distance shooting, clearly revealing subtle defects on the support surface, such as cracks and damage, thus improving the effectiveness and accuracy of long-distance detection. The application of the starlight-level image sensor significantly enhances the camera 2's light sensitivity in low-light environments, enabling clear and bright images even in dimly lit conditions such as under bridges. This overcomes the poor imaging performance of traditional cameras in low-light environments, ensuring high-quality detection under various lighting conditions. The combination of these two key technologies allows the detection equipment to effectively cope with the complex environment of bridge inspection, achieving long-distance, high-definition, all-weather support surface inspection.

[0056] In one embodiment, the handheld end of the telescopic pole 1 is equipped with a hand strap 9. It is understood that the hand strap 9 provides an extra layer of safety for the operator. During use, the operator can wear the hand strap 9 around their wrist. Even in the event of an unstable grip or an accident, the hand strap 9 can prevent the telescopic pole 1 and components mounted on its front end, such as the camera and pan-tilt unit, from completely slipping out of their hand and falling, thus avoiding equipment damage or personal injury. This improves the safety of equipment use, especially when conducting tests in special environments such as at high altitudes or on water, where the safety function of the hand strap 9 is even more crucial.

[0057] In one embodiment, the controllable rotating pan-tilt head 3 has a horizontal rotation axis and a vertical rotation axis to drive the remotely controlled zoom camera 2 to rotate in both the horizontal and vertical directions. This means that the rotating pan-tilt head 3 has dual-axis rotation capability, enabling the camera 2 to adjust its angle in both the horizontal and vertical directions. It can be understood that the dual-axis rotating pan-tilt head configuration provides greater flexibility and adjustability to the camera 2's shooting angle. Through the coordinated operation of the horizontal and vertical rotation axes, the camera 2 can be adjusted to any angle within a 360° horizontal range and a certain vertical angle range, facilitating operators to shoot the support from different angles and orientations. This avoids blind spots that may result from shooting from a single angle, allowing for more comprehensive and detailed inspection of all surfaces of the support, improving inspection coverage and accuracy. Especially for supports with complex structures, the dual-axis rotating pan-tilt head can better meet the needs of multi-angle inspection.

[0058] In one embodiment, the battery configured in this embodiment is a lithium battery. It is understood that using lithium batteries as a power source has advantages such as high energy density, light weight, small size, and long cycle life. Compared to traditional lead-acid or nickel-cadmium batteries, lithium batteries can provide longer battery life while reducing the overall weight of the device, improving its portability and facilitating long-term handheld operation and transportation. The long cycle life of lithium batteries also reduces the frequency of battery replacement, lowers maintenance costs, and improves the economic efficiency and practicality of the device.

[0059] In one embodiment, the gimbal mounting plate 5 and the battery box 6 are respectively fixedly welded to the connecting end plate 71 of the X-shaped plate 7. It is understood that welding is a high-strength and highly reliable connection method. By welding the gimbal mounting plate 5 and the battery box 6 to the connecting end plate 71 of the X-shaped plate 7, a robust overall structure is formed, ensuring the strength and rigidity of the clamping connector 4. This allows it to withstand the weight of the controllable rotating gimbal 3 and the camera 2, as well as various external forces that may occur during use. This prevents loosening or detachment of components, improving the stability and reliability of the equipment. Especially in harsh bridge inspection environments, welding connections ensure the long-term stable operation of the equipment.

[0060] In one embodiment, the clamping opening 72 has a shape that matches the outer surface of the telescopic end of the telescopic rod 1. It can be understood that matching the clamping opening 72 to the outer surface of the telescopic end of the telescopic rod 1 increases the contact area between the clamping opening 72 and the telescopic rod 1, allowing the clamping force to be distributed more evenly on the surface of the telescopic rod 1, avoiding localized stress concentration, and improving the stability and reliability of the clamping. The matching clamping opening 72 can better fit the outer surface of the telescopic rod 1, reducing the possibility of slippage and rotation, enhancing the clamping effect, ensuring that the equipment will not loosen or fall off during use, and improving the safety of the inspection.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
