Description

Technical Field

[0001] This application relates to the field of building inspection technology, and in particular to pier monitoring devices. Background Technology

[0002] Hollow piers are widely used in railway and highway bridge construction due to their significant performance advantages. They possess high lateral stiffness and a reasonable combination of longitudinal and transverse dimensions, making them well-suited to flowing water characteristics, effectively reducing material usage, and exhibiting outstanding construction adaptability. Based on differences in cross-sectional shape, hollow piers encompass various types, including rectangular piers, circular piers, single-span or multi-span round-ended piers, single-span or multi-span elliptical piers, and rhomboid piers. Furthermore, hollow piers typically employ high-strength reinforced concrete structures with thinner walls. Depending on the stress characteristics, pier height, and structural requirements, pier heights generally range from 30m to 50m, while wall thicknesses range from 30cm to 50cm. This significantly reduces the pier's self-weight, shrinks its cross-sectional dimensions, and lowers the load on the foundation, resulting in a lighter appearance and more economical cost-effectiveness while ensuring safety.

[0003] However, due to the unique structure of hollow piers, subsequent inspections present difficulties. On one hand, the relatively enclosed interior of hollow piers is often flooded and polluted, creating an extremely complex inspection environment that makes it difficult for maintenance personnel to conduct inspections for extended periods. On the other hand, the considerable height of the hollow piers, coupled with poor internal lighting, poses significant safety risks when maintenance personnel use ladders and platforms for inspections. These problems severely impact the efficiency and quality of hollow pier maintenance, necessitating the development of new technical solutions. Utility Model Content

[0004] Therefore, it is necessary to provide a pier body monitoring device to address the difficulty of later-stage inspection of hollow piers.

[0013] According to one embodiment of this application, the moving mechanism includes a slider having a groove that extends vertically through the slider, and a guide rail passing through the groove in a vertical direction.

[0014] According to one embodiment of this application, the slider has a lateral opening on one side in the horizontal direction, the lateral opening connecting the slide groove and the outer wall of the slider; the guide rail includes a first component plate, a second component plate and a third component plate, the first component plate, the second component plate and the third component plate all extending in the vertical direction, the third component plate being located between the first component plate and the second component plate and being perpendicularly fixed to the first component plate and the second component plate respectively, the first component plate passing through the slide groove, the second component plate being located outside the slider, and the third component plate passing through the lateral opening.

[0015] The aforementioned pier monitoring device can move the detection mechanism up and down within the pier cavity by driving the moving mechanism along the guide rail through a lifting mechanism.

During this process, maintenance personnel do not need to enter the pier cavity, which can effectively reduce the difficulty of detection and improve work efficiency and safety.

[0034] See Figure 1 An embodiment of this application provides a pier monitoring device including a guide rail 100, a moving mechanism 200, a lifting mechanism 300, and a detection mechanism 400. The guide rail 100 is vertically installed in the inner cavity 810 of the pier 800. The moving mechanism 200 is slidably installed on the guide rail 100. The lifting mechanism 300 is connected to the moving mechanism 200 and configured to drive the moving mechanism 200 to move up and down along the guide rail 100. The detection mechanism 400 is installed on the moving mechanism 200 and is used to collect image information of the inner cavity 810 of the pier 800.

[0035] The hollow pier body 800 has an inner cavity 810 extending vertically and forming an opening at the top. The guide rail 100, a rigid structure, extends from the top opening of the inner cavity 810 to the bottom or near the bottom. As a rigid component, the guide rail 100 provides good limiting for the moving mechanism 200, ensuring the stability of its lifting and lowering, and thus ensuring that the detection mechanism 400 can clearly and accurately obtain image information of the inner cavity 810 of the pier body 800. The guide rail 100 provides track support for the sliding of the moving mechanism 200 and is the basic guiding structure of the entire monitoring device, determining the path and direction of the moving mechanism 200's lifting and lowering. The moving mechanism 200 is slidably mounted on the guide rail 100 and can move up and down under the constraint of the guide rail 100, enabling the detection mechanism 400 to monitor different height positions within the inner cavity 810 of the pier body 800. The lifting mechanism 300 is connected to the moving mechanism 200. Its function is to drive the moving mechanism 200 to move up and down along the guide rail 100, providing power to the moving mechanism 200 so that it can reach various monitoring heights of the inner cavity 810 of the pier body 800. The detection mechanism 400 is installed on the moving mechanism 200 and is used to collect image information of the inner cavity 810 of the pier body 800. The collected image data provides a basis for subsequent analysis of the condition of the inner cavity 810 of the pier body 800.

[0036] When monitoring of the inner cavity 810 of the pier 800 is required, the lifting mechanism 300 is activated. The lifting mechanism 300 begins operation, generating power. Under the power generated by the lifting mechanism 300, the moving mechanism 200 slides along the guide rail 100, achieving lifting and lowering movement. During the lifting and lowering process, the moving mechanism 200 drives the detection mechanism 400 mounted on it to move together. The detection mechanism 400, along with the moving mechanism 200, reaches different height positions within the inner cavity 810 of the pier 800, acquiring image information of the inner cavity 810 at each position. This image information may include the structure, surface, and other conditions of the inner cavity 810 of the pier 800 at different heights. The acquired image information can be transmitted to external data processing equipment via wired or wireless means. Technicians analyze and process this image information to determine whether there are defects such as cracks, spalling, or deformation in the inner cavity 810 of the pier 800, as well as the location, size, and severity of these defects.

[0037] Through the cooperation of the guide rail 100 and the moving mechanism 200, the detection mechanism 400 can move and acquire images at different heights within the inner cavity 810 of the pier 800, achieving comprehensive monitoring of the inner cavity 810 of the pier 800. This avoids blind spots that may exist in traditional monitoring methods and enables timely detection of problems at various locations within the inner cavity 810 of the pier 800. The lifting mechanism 300 can precisely control the lifting speed and position of the moving mechanism 200, allowing the detection mechanism 400 to acquire image information at appropriate times and locations, improving monitoring efficiency and accuracy. Simultaneously, the image information can intuitively reflect the condition of the inner cavity 810 of the pier 800, facilitating analysis and judgment by technicians. When monitoring using the pier monitoring device of this embodiment, maintenance personnel do not need to enter the inner cavity 810 of the pier 800, effectively reducing the difficulty of detection and improving operational efficiency and safety.

[0038] In some embodiments, the detection mechanism 400 includes a camera 410 and a steering mechanism 420. The camera 410 is movably mounted to the moving mechanism 200. The steering mechanism 420 is mounted to the moving mechanism 200, connected to the camera 410, and is used to drive the camera 410 to rotate.

[0039] Driven by the steering mechanism 420, the camera 410 can capture images of the inner cavity 810 of the pier 800 from different angles. For example, the camera 410 can first rotate horizontally by a certain angle to capture images of the inner cavity 810 of the pier 800 at different heights in the same direction; then, the steering mechanism 420 can adjust the horizontal angle of the camera 410 so that the camera 410 can capture images of the inner cavity 810 of the pier 800 at different heights in other directions. Through this multi-angle shooting method, more comprehensive and detailed image information of the inner cavity 810 of the pier 800 can be obtained.

[0040] In this embodiment, the steering mechanism 420 drives the camera 410 to rotate, enabling the camera 410 to capture images of the inner cavity 810 of the pier 800 from multiple angles. This significantly expands the monitoring range and avoids blind spots caused by the camera 410's fixed-angle shooting, achieving comprehensive monitoring of the inner cavity 810 of the pier 800. Multi-angle image acquisition provides richer information, helping technicians to more accurately assess the condition of the inner cavity 810 of the pier 800. For example, by comparing images from different angles, minute cracks, deformations, and other defects on the surface of the inner cavity 810 of the pier 800 can be more clearly identified, improving the accuracy and reliability of monitoring. Furthermore, the structure of the inner cavity 810 of the pier 800 may be complex, with various protrusions and depressions. The rotatable camera 410 can better adapt to these complex structures, flexibly adjusting the shooting angle to ensure that images of key areas are captured, meeting the monitoring needs of different pier 800 structures.

[0041] For example, the steering mechanism 420 includes a drive motor, a drive gear, a driven gear, and a rotating shaft for mounting the camera 410. The drive motor is a servo motor, fixed to the moving mechanism 200. The drive gear is mounted on the motor's output shaft, and the driven gear meshes with the drive gear and is fixed to the rotating shaft. The camera 410 is mounted on the rotating shaft. When it is necessary to drive the camera 410 to rotate, the drive motor starts, driving the drive gear to rotate. Since the drive gear and driven gear mesh with each other, the rotation of the drive gear will drive the driven gear to rotate, thereby causing the rotating shaft to rotate, ultimately achieving the rotation of the camera 410. By controlling the forward and reverse rotation of the motor, the rotation direction of the camera 410 can be controlled.

[0042] Furthermore, the steering mechanism 420 may also include a controller connected to the drive motor for controlling the operation of the drive motor.

[0043] Of course, the camera 410 can be mounted on the moving mechanism 200 via an electric pan-tilt head, and the rotation drive structure in the electric pan-tilt head constitutes the aforementioned steering mechanism 420.

[0044] In some embodiments, the detection mechanism 400 further includes a first press switch 430 and a second press switch 440. The first press switch 430 is mounted on the lower side of the moving mechanism 200 and electrically connected to the steering mechanism 420. The steering mechanism 420 is configured to drive the camera 410 to rotate in a horizontal first direction when the first press switch 430 is pressed. The second press switch 440 is mounted on the upper side of the moving mechanism 200 and electrically connected to the steering mechanism 420. The steering mechanism 420 is configured to drive the camera 410 to rotate in the opposite direction of the first direction when the second press switch 440 is pressed.

[0045] The first push-button switch 430 can be triggered by cooperating with the bottom of the inner cavity 810 of the pier body 800 or by an additional compression structure. The second push-button switch 440 can be triggered manually by pressing when the moving mechanism 200 moves to the top of the inner cavity 810 of the pier body 800, or by cooperating with the additional compression structure above. For example, the first push-button switch 430 and the second push-button switch 440 are microswitches, which have advantages such as small size, high sensitivity, and reliable operation. The microswitch is electrically connected to the controller of the drive motor. When subjected to external pressure, the contacts inside the microswitch will quickly close or open, thereby sending an electrical signal to the steering mechanism 420. For example, the first push-button switch 430 and the second push-button switch 440 are self-resetting button switches. After the button is pressed or squeezed, the switch connects the circuit; after the button is released, the button automatically resets, and the switch disconnects the circuit.

[0046] When the moving mechanism 200 descends under the drive of the lifting mechanism 300, the first pressing switch 430 contacts and is pressed against the bottom of the inner cavity 810 of the pier body 800 or an additional extrusion structure. At this time, the first pressing switch 430 sends an electrical signal to the steering mechanism 420. After receiving the signal, the steering mechanism 420 starts and drives the camera 410 to rotate in the first horizontal direction (e.g., clockwise). The camera 410 begins to acquire images of the area in that direction. When the moving mechanism 200 rises to the top of the inner cavity 810 of the pier body 800, the operator manually presses the second pressing switch 440. Alternatively, when the second pressing switch 440 contacts and is pressed against the additional extrusion structure above, the second pressing switch 440 sends an electrical signal to the steering mechanism 420. After receiving the signal, the steering mechanism 420 drives the camera 410 to rotate in the opposite direction of the first direction (e.g., counterclockwise). The camera 410 acquires images of the area in the opposite direction. In this way, the camera 410 can rotate in different directions during the rising and falling process, and complete the monitoring of the inner cavity 810 of the pier body 800 from multiple angles.

[0047] This embodiment utilizes a push-button switch to control the rotation direction of the camera 410, which avoids repeatedly acquiring image information in the same direction during ascent and descent, effectively improving monitoring efficiency. Furthermore, it eliminates the need for complex programming or operating procedures, and eliminates the need for operators to enter the hollow pier, effectively reducing operational difficulty and labor costs.

[0048] Combination Figure 2 In some embodiments, the pier monitoring device further includes at least one positioning protrusion 500, which is fixed to the lower side of the moving mechanism 200. Further, the pier monitoring device also includes a first contact member 600, located below the moving mechanism 200 and fixedly connected to the guide rail 100. The upper surface of the first contact member 600 has at least one positioning groove 610, which is aligned vertically with the positioning protrusion 500. The first contact member 600 is configured to engage with the first push switch 430 when the moving mechanism 200 moves downward to its maximum stroke position, and the positioning protrusion 500 is inserted into the positioning groove 610.

[0049] As the lifting mechanism 300 drives the moving mechanism 200 downward, the positioning protrusion 500 begins to approach the positioning groove 610 as the moving mechanism 200 gradually approaches its maximum stroke position. When the moving mechanism 200 reaches its maximum stroke position, the positioning protrusion 500 inserts into the positioning groove 610. Simultaneously, the first contact member 600 contacts and presses against the first push switch 430, triggering the first push switch 430 to send an electrical signal to the steering mechanism 420. The steering mechanism 420 then drives the camera 410 to rotate along a horizontal first direction. During this process, the insertion and engagement of the positioning protrusion 500 and the positioning groove 610 positions and fixes the moving mechanism 200, preventing additional shaking or displacement of the moving mechanism 200 when pressed by the first contact member 600. This ensures the stability of the camera 410 during rotation and facilitates accurate control of the camera 410's rotation angle. Furthermore, it reduces the risk of damage to other components caused by the shaking or displacement of the moving mechanism 200, extends the service life of the device, and improves the reliability of the device in complex working environments.

[0050] In some embodiments, two positioning protrusions 500 are provided, which are respectively placed on both sides of the first push switch 430 in the horizontal direction, and two positioning grooves 610 are provided corresponding to the positioning protrusions 500.

[0051] Two positioning protrusions 500 are positioned horizontally on both sides of the first push switch 430, forming a symmetrical layout. At the same time, two positioning grooves 610 are also provided on the upper surface of the first contact member 600. The positions of the positioning grooves 610 match the positioning protrusions 500, ensuring that when the moving mechanism 200 descends to a specific position, both positioning protrusions 500 can accurately insert into the corresponding positioning grooves 610.

[0052] The two positioning protrusions 500 cooperate with the two positioning grooves 610 to form a dual-point positioning, simultaneously limiting the horizontal movement and rotation of the moving mechanism 200, greatly improving the positioning accuracy. In addition, the positioning protrusions 500 can also protect the first push switch 430, preventing it from being damaged by accidental contact with obstacles or excessive pressure.

[0053] In some embodiments, the positioning protrusion 500 is a tapered protrusion with a horizontal cross-sectional area decreasing from the top to the bottom, and the positioning groove 610 is a tapered groove with a horizontal cross-sectional area decreasing from the top to the bottom.

[0054] Since both the positioning protrusion 500 and the positioning groove 610 are conical, the conical structure allows the positioning protrusion 500 to automatically guide and gradually penetrate into the positioning groove 610 during the insertion process. As the moving mechanism 200 continues to descend, the contact area between the positioning protrusion 500 and the positioning groove 610 gradually increases, and the fit between them becomes increasingly tight. When the moving mechanism 200 reaches its maximum stroke position, the positioning protrusion 500 is fully inserted into the positioning groove 610. At this time, the first contact 600 engages with the first press switch 430, triggering the first press switch 430 to send an electrical signal to the steering mechanism 420. The steering mechanism 420 then drives the camera 410 to rotate along the first horizontal direction. The conical shape design gives the positioning protrusion 500 a certain degree of tolerance during the insertion process; even with slight positional deviations, the conical structure can automatically adjust and achieve a tight fit.

[0055] The positioning protrusion 500 in this embodiment can be a matching conical, pyramidal, or stepped conical structure, etc., and is not specifically limited here.

[0056] In some embodiments, the pier monitoring device further includes a second contact 700 located above the moving mechanism 200 and fixedly connected to the guide rail 100. The second contact 700 is configured to engage with the second push switch 440 when the moving mechanism 200 moves upward to the maximum position of its stroke.

[0057] In some embodiments, the lifting mechanism 300 includes a traction component 310 and a sling 320. The traction component 310 is fixed to the top outer side of the pier body 800; one end of the sling 320 is fixedly connected to the moving mechanism 200, and the other end is fixedly connected to the traction component 310.

[0058] For example, the traction component 310 can be an electric winch. When the moving mechanism 200 needs to be raised, the traction component 310 starts working, the motor inside the electric winch starts, and drives the drum to rotate clockwise (taking a common winch structure as an example). Since one end of the sling 320 is fixed to the drum, as the drum rotates, the sling 320 will gradually wind around the drum. The moving mechanism 200, connected to the other end of the sling 320, will be subjected to an upward pulling force, thereby overcoming its own weight and possible frictional resistance, and moving upward along the pier body 800. When the moving mechanism 200 needs to be lowered, the operation of the traction component 310 is reversed. The motor of the electric winch drives the drum to rotate counterclockwise, and the sling 320 is gradually released from the drum. Under the action of its own weight, the weight of the detection mechanism 400, and possible auxiliary gravity (such as the weight of the counterweight), the moving mechanism 200 moves downward along the pier body 800. During descent, the traction component 310 can adjust the descent speed of the moving mechanism 200 by controlling the rotation speed of the drum, ensuring a smooth and safe descent process.

[0059] Compared to some complex lifting mechanisms 300, this simple structure reduces the probability of failure and lowers maintenance costs. For example, in some devices using hydraulic systems for lifting, problems such as oil leaks and aging seals may occur. The combination of the traction component 310 and the sling 320 avoids these common hydraulic system failures. The traction component 310 is fixed to the outer top of the pier 800, and the sling 320 connects the moving mechanism 200 and the traction component 310. The installation process is relatively simple, requiring no complex piping or electrical wiring, thus shortening installation time and improving construction efficiency. Furthermore, by adjusting the length of the sling 320 and the performance parameters of the traction component 310, this lifting mechanism 300 can adapt to the monitoring needs of piers 800 at different heights. For shorter piers 800, a shorter sling 320 and a lower-power traction component 310 can be used; for taller piers 800, a longer sling 320 and a higher-power traction component 310 can be used, demonstrating strong versatility.

[0060] In some embodiments, the lifting mechanism 300 further includes at least one guide component 330, which includes a fixed seat and a guide wheel rotatably connected to the fixed seat; the sling 320 is wound around the guide wheel at a position between the traction component 310 and the moving mechanism 200.

[0061] Because the guide wheel is rotatably connected to the fixed base, it rotates along with the sling 320 during its movement. For example, when the sling 320 moves up or down, the guide wheel rotates clockwise or counterclockwise accordingly, guiding the sling 320's movement along a preset path. This ensures the sling 320 always moves along the correct trajectory, preventing problems such as deviation or entanglement during its movement.

[0062] Optionally, the mounting base includes a mounting shaft and a pair of parallel mounting plates. The mounting shaft is horizontally positioned, and its two ends are fixedly connected to the mounting plates respectively. The guide wheel is located between the pair of mounting plates and is connected to the mounting shaft.

[0063] For example, the fixed seat and guide wheel are located above the pier body 800. The portion of the sling 320 located on one side of the guide wheel is arranged horizontally and connected to the traction assembly 310, while the portion located on the other side of the guide wheel is arranged vertically and connected to the moving mechanism 200. The guide assembly 330 can prevent the sling 320 from rubbing against the pier body 800, which helps to reduce the lifting resistance of the moving mechanism 200, making the pier monitoring device operate more stably, and also preventing the sling 320 from being damaged by friction during long-term operation of the pier monitoring device.

[0064] Combination Figure 3In some embodiments, the moving mechanism 200 includes a slider 210, the slider 210 having a groove 211 that extends vertically through the slider 210, and a guide rail 100 passing through the groove 211 in a vertical direction.

[0065] The cooperation between the slide groove 211 and the guide rail 100 not only enables the sliding of the slider 210, but also serves as a guide and constraint. The guide rail 100 restricts the slider 210 to move only in the vertical direction, preventing it from deviating or wobbling in the horizontal or other directions. For example, when the lifting mechanism 300 is subjected to external disturbances (such as wind or vibration) during operation, the guide rail 100 ensures that the slider 210 always moves along the correct path, guaranteeing the accuracy and stability of the moving mechanism 200. Compared with some moving mechanisms 200 that use complex mechanical structures, this simple structure reduces the probability of failure and lowers maintenance costs. For example, in some complex mechanical transmission moving mechanisms 200, there may be multiple gears, chains, and other components, which are prone to wear, jamming, and other problems. The cooperation between the slider 210 and the guide rail 100 avoids the failure risks caused by these complex components.

[0066] In some embodiments, the slider 210 has a lateral opening 212 on one side in the horizontal direction, the lateral opening 212 connecting the slide groove 211 and the outer wall of the slider 210. The width of the lateral opening 212 is smaller than the width of the slide groove 211, so that the lateral opening 212 and the slide groove 211 together form a T-shaped groove structure. The guide rail 100 includes a first constituent plate 110, a second constituent plate 120 and a third constituent plate 130, all of which extend in the vertical direction. The third constituent plate 130 is located between the first constituent plate 110 and the second constituent plate 120 and is fixed perpendicularly to the first constituent plate 110 and the second constituent plate 120 respectively. For example, the guide rail 100 adopts an I-beam structure, where two parallel plates of the I-beam respectively form the first constituent plate 110 and the second constituent plate 120, and the other plate forms the third constituent plate 130. The first component plate 110 passes through the slide groove 211, the second component plate 120 is located outside the slider 210, and the third component plate 130 passes through the lateral opening 212.

[0067] The aforementioned mating structure provides vertical guidance for the slider 210, ensuring that it can only move vertically and preventing it from deviating in the horizontal or other directions. This guarantees the stability and accuracy of the slider 210's movement. The installation process of the slider 210 and guide rail 100 is relatively simple; the slider 210 is simply fitted onto the first component plate 110 of the guide rail 100 via the groove 211, and the third component plate 130 passes through the lateral opening 212. Furthermore, the structure of the guide rail 100 can be flexibly arranged according to the actual conditions of the pier 800, improving the installation efficiency and adaptability of the device. For example, during on-site construction, the slider 210 and guide rail 100 can be quickly installed onto the pier 800, shortening the construction cycle.

[0068] The pier monitoring device of this embodiment can detect different heights of the hollow pier's inner cavity 810. On the one hand, it effectively reduces the difficulty of detection. Previously, maintenance personnel faced many difficulties when entering the inner cavity 810 of the pier 800 for inspection, such as limited space, insufficient lighting, and complex environment. The inspection work was not only inefficient but also prone to oversights. However, with the monitoring device of this embodiment, the inspection personnel can operate remotely from outside and easily obtain image information of the inner cavity 810 of the pier 800, greatly simplifying the inspection process. On the other hand, it improves work efficiency and safety. Maintenance personnel do not need to stay in the inner cavity 810 of the pier 800 for a long time, avoiding safety risks that may be caused by environmental factors or unexpected situations. At the same time, the device can quickly and accurately collect a large amount of image information, saving time for subsequent analysis and processing and improving overall work efficiency. In summary, the pier monitoring device of this embodiment provides a safe, convenient, and efficient solution for the inspection of hollow piers.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
