Description

Technical Field

[0001] The invention belongs to the technical field of steel tube detection, and particularly relates to a steel tube concrete arch rib void detection device. Background Art

[0002] Concrete-filled steel tube arch bridges are a new type of bridge structure developed in recent years in my country. They offer the advantages of light weight, high strength, strong deformation resistance, and high load-bearing capacity. They also require minimal materials, are lightweight for installation, are easy to construct, require a short construction period, and require minimal maintenance, making them an ideal structural form for long-span arch bridges. The concrete within the poured tubes is hidden, making it impossible to directly observe debonding or voids in the concrete. Therefore, post-cast arch ribs must be inspected for voids, and regular bridge inspections must also include checking for voids in concrete-filled steel tubes.

[0003] Existing detection methods include ultrasound and infrared imaging. Among them, ultrasound is more effective and does not damage steel tube concrete. It can also detect the area of ​​the void area. When the existing detection device detects circular steel tube concrete arch ribs, the unstable position of the steel tube will cause it to shift or shake during the detection process, making it impossible for the detector to accurately aim at the specific area of ​​the steel tube, resulting in some inner wall areas not being detected, resulting in detection omissions.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] like Figures 1 to 9 As shown, the present invention provides a technical solution: a steel tube concrete arch rib void detection device, comprising a detection platform 1, the top of the detection platform 1 is fixedly connected with a fixing frame 2 and a mounting frame 3, the top of the fixing frame 2 is fixedly connected with a discharge platform 4, the inner wall of the mounting frame 3 is rotatably connected with a rotating shaft 9, the outer wall of the rotating shaft 9 is fixedly connected with a sliding platform 5, the discharge platform 4 and the sliding platform 5 are V-shaped, and the top of the discharge platform 4 is used to place multiple steel tube concrete arch ribs for detection, a control panel 6 is provided above the discharge platform 4 and the sliding platform 5, and a plurality of detectors 7 are fixedly connected to the bottom of the control panel 6, a rotating component for driving the sliding platform 5 to rotate is provided below the sliding platform 5, and a rolling component and a limiting component for driving the steel pipe to roll along the inclined surface of the sliding platform 5 are provided above the sliding platform 5.

[0032] During operation: This device is suitable for detecting the condition of concrete adhesion on the inner wall of a circular steel pipe after concrete is poured. A plurality of steel pipes to be detected are placed above the unloading platform 4. Since the unloading platform 4 and the sliding platform 5 are V-shaped, the first steel pipe will be stuck in the bottom notch where the two intersect each other, and the remaining steel pipes are parked in turn directly above the unloading platform 4. During detection, the rotating component is first started to drive the sliding platform 5 to rotate with the central axis 9 as the axis. When a part of the sliding platform 5 overlaps with the inner wall of the unloading platform 4, the two are transformed from a V-shape to a completely straight inclined surface. At this time, the limit component moves along the inclined surface of the sliding platform 5, and the first steel pipe loses its restraint and slides along the inclined surface. The rolling component causes the steel pipe to roll during the sliding process, which is controlled by the control The detection mechanism composed of the panel 6 and the detector 7 moves with the sliding platform 5. When the steel pipe rolls, its entire outer wall surface will face directly below the detector 7 at a certain moment. The detector 7 penetrates the steel pipe body by emitting ultrasonic signals to detect whether there are defects in the inner wall concrete. Multiple detectors 7 can scan various areas of the entire outer wall surface of the steel pipe during the rolling process of the steel pipe. The limit component can accurately control the rolling speed of the steel pipe on the surface of the sliding platform 5 to ensure that the detection mechanism is always directly above the steel pipe; the rolling component promotes the steel pipe to fall along the inclined surface of the sliding platform 5 in a rolling posture. After the detection is completed, the sliding platform 5 is reset, and the second steel pipe automatically moves to the position of the original first steel pipe for subsequent detection work;

[0033] Through the above embodiment, through the rotating component, the rotating component can drive the sliding platform 5 to rotate with the central axis 9 as the axis. When the sliding platform 5 rotates and a part of it overlaps with the inner wall of the unloading platform 4, the unloading platform 4 and the sliding platform 5 will be transformed from the original V-shape to a completely straight inclined surface. This change in shape creates conditions for the subsequent rolling detection of steel pipes, ensures the comprehensiveness and accuracy of the detection of concrete defects on the inner wall of the steel pipe, realizes the continuous process of steel pipe detection, and further improves the consistency and efficiency of the detection; and with the mutual cooperation of the rolling component and the limit component, under the action of the rolling component and the limit component, the steel pipe can complete the detection in sequence according to the predetermined rhythm and speed. The rolling component prompts the steel pipe to roll during the sliding of the inclined surface of the sliding platform 5 to ensure that the detection of concrete defects on the inner wall of the steel pipe is not missed, which greatly improves the comprehensiveness of the detection. The control of the limit component enables the detection mechanism to always remain directly above the steel pipe, enhancing the accuracy of the detection.

[0034] like Figures 2 to 4 As shown, the rotating assembly includes a pair of arc-shaped telescopic rods 11, one end of the arc-shaped telescopic rods 11 is fixedly connected to one side of the mounting frame 3, the end of the arc-shaped telescopic rods 11 away from the mounting frame 3 is fixedly connected to a arc-shaped slider 13, the outer wall of the arc-shaped slider 13 is slidably connected to an arc-shaped slide seat 12, the arc-shaped slide seat 12 is fixedly connected to the bottom of the unloading platform 4, and a fixing part 14 is fixedly connected between the two arc-shaped sliders 13, and the fixing part 14 is fixedly connected to the bottom of one end of the sliding platform 5.

[0035] During operation: During the detection process, the control system controls the arc-shaped telescopic rod 11 to extend. As the arc-shaped telescopic rod 11 extends, it pushes the arc-shaped slider 13 to slide along the inner groove wall of the arc-shaped slide seat 12. During the sliding process, the arc-shaped slider 13 will drive one end of the sliding platform 5 to rotate along the arc trajectory with the help of the fixing member 14. Since the sliding platform 5 rotates with the rotating shaft 9 as the axis, when one end of the sliding platform 5 is tilted, the other end will rotate downward accordingly; as the sliding platform 5 continues to rotate, until a part of the sliding platform 5 overlaps with the inner wall of the unloading platform 4, the surface between the unloading platform 4 and the sliding platform 5 is transformed from the original V-shape to a straight inclined surface, and under the action of gravity, it is placed at the intersection of the unloading platform 4 and the sliding platform 5, that is, the original V The first steel pipe at the bottom groove of the U-shaped pipe will be subjected to the force of sliding down along the straight inclined surface. At the same time, the limit assembly starts to work and moves along the inclined surface of the sliding platform 5, gradually releasing the restraint on the first steel pipe. At this time, the rolling assembly plays a role, prompting the steel pipe to start rolling in the process of sliding along the inclined surface, and the detection mechanism composed of the control panel 6 and the detector 7 will move with the rotation of the sliding platform 5, and always remain directly above the steel pipe. In the process of the steel pipe rolling, its entire outer wall surface will face directly below the detector 7 at a certain moment. The detector 7 penetrates the steel pipe body by emitting ultrasonic signals to detect whether there are defects in the inner wall concrete. Multiple detectors 7 can scan various areas of the entire outer wall surface of the steel pipe as they follow the rolling of the steel pipe.

[0036] like Figures 2 to 3 As shown, protective plates 8 are fixedly connected to both sides of the top of the unloading platform 4. The length of the two protective plates 8 is the same as the length of the inclined surface formed by overlapping the unloading platform 4 and the sliding platform 5. A locking component is provided at the top of one end of the sliding platform 5 to limit the remaining steel pipes.

[0037] During operation: the protective plate 8 plays a dual important role. On the one hand, it can ensure that the cross-sections of all steel pipes placed above the unloading platform 4 remain flush, so that the steel pipes are arranged neatly and orderly. On the other hand, when the unloading platform 4 overlaps with the sliding platform 5 to form an inclined surface, when the steel pipe slides along the inclined surface of the sliding platform 5, the protective plate 8 can effectively limit the position of the steel pipe to prevent the steel pipe from positional displacement during the sliding process, ensuring that the detection mechanism can accurately detect the steel pipe. The role of the positioning component is that when the sliding platform 5 rotates under the drive of the rotating component, it will limit the remaining steel pipes to prevent these remaining steel pipes from sliding along the inclined surface of the sliding platform 5. In this way, each time the detection is performed, only the steel pipe close to the front end can slide smoothly and be detected, ensuring the orderliness and accuracy of the detection work.

[0038] like Figures 8 and 9As shown, the positioning assembly includes two limit plates 10, both of which are arc-shaped and have pointed ends. The distance between the two limit plates 10 is the same as the diameter of the steel pipe, and one end of the two limit plates 10 is flush with the upper surface of the unloading platform 4.

[0039] During operation: When the sliding platform 5 rotates, it will drive the two limit plates 10 to gradually enter the gap between the remaining steel pipes. Since one end of the limit plate 10 is a pointed design, this pointed structure can be inserted into the gap between the steel pipes more smoothly, reducing resistance and jamming during the insertion process. Because the distance between the two limit plates 10 is the same as the diameter of the steel pipe, when the limit plates 10 are fully inserted into the gap between the steel pipes, they will fit tightly on both sides of the steel pipe, effectively blocking the remaining steel pipes and limiting their movement. In this way, in each detection process, only the steel pipe at the front end to be detected can smoothly move along the sliding platform 5 The inclined surface slides, and the remaining steel pipes are firmly restricted on the unloading platform 4 by the limit plate 10, which ensures the orderliness and accuracy of the detection work and avoids the situation where multiple steel pipes slide at the same time and cause detection confusion; and when 5 is reset in the opposite direction, the remaining steel pipes lose the restraint of the limit plate 10. At this time, the remaining steel pipes originally blocked by the limit plate 10 will automatically move forward along the surface of the unloading platform 4 under the action of gravity and the pushing of subsequent steel pipes. During the movement, the first steel pipe will reach the intersection of the unloading platform 4 and the sliding platform 5 again, that is, the original V-shaped bottom groove position, waiting for the next rotation of the sliding platform 5 to start the detection process.

[0040] like Figures 6 to 9 As shown, the limiting assembly includes a locking wheel 15, the inner wall of the locking wheel 15 is fixedly connected to a rotating rod 16, both ends of the rotating rod 16 are rotatably connected to a connecting piece 17, the bottom of the connecting piece 17 is fixedly connected to an electric slider 18, and the outer wall of the electric slider 18 is provided with a driving assembly that drives the locking wheel 15 to move.

[0041] During operation: When the first steel pipe is stuck in the V-shaped groove formed by the unloading platform 4 and the sliding platform 5, the outer wall of the steel pipe will fit tightly with the outer wall of the positioning wheel 15. Then, the rotating component starts to drive the sliding platform 5 to rotate. At this time, the position of the positioning wheel 15 will change accordingly. In the early stage of the rotation of the sliding platform 5, the steel pipe will first slide a short distance along the surface of the sliding platform 5 and always keep in contact with the outer wall of the positioning wheel 15. At the same time, the driving component starts, and the electric slider 18 drives the rotating rod 16 and the positioning wheel 15 to slide along the sliding platform 5. The steel pipe slides in the direction of the inclined surface. During the sliding process of the blocking wheel 15, the steel pipe will always maintain a fit relationship with the blocking wheel 15 under the action of its own gravity. When the blocking wheel 15 slides, it will interact with the rolling component, so that the blocking wheel 15 has a tendency to rotate. During the rotation process, the blocking wheel 15 will generate friction with the outer wall of the steel pipe. This friction will promote the rotation of the steel pipe. Finally, the steel pipe slides along the inclined surface of the slide platform 5 in the form of rolling under the drive of the blocking wheel 15 and the action of its own gravity.

[0042] like Figures 5 to 8 As shown, the drive assembly includes two electric rails 19, which are L-shaped. The electric slider 18 is slidably connected to the inner wall of the electric rail 19. The inner wall of the sliding platform 5 is fixedly connected to a connecting rod 20, and the outer wall of the connecting rod 20 is slidably connected to an arcuate guide rail 21. The arcuate guide rail 21 is fixedly connected to the inner wall of the protective plate 8, and the two ends of the connecting rod 20 are respectively fixedly connected to the side surfaces of the electric rail 19.

[0043] During operation: When the sliding platform 5 starts to rotate under the action of the rotating assembly, the connecting rod 20 will slide along the inner wall of the arc-shaped guide rail 21. During the sliding process, the connecting rod 20 will drive the electric guide rail 19 to move synchronously, ensuring that the electric guide rail 19 always remains parallel to the inclined surface of the sliding platform 5. When current is applied to the electric guide rail 19, the electric slider 18 will slide along the inner wall of the electric guide rail 19. When the electric slider 18 slides along the first section of the inner wall of the electric guide rail 19, the locking wheel 15 will move in a direction parallel to the top of the sliding platform 5. During this period, During the test, the steel pipe always fits tightly against the outer wall of the positioning wheel 15. The movement of the positioning wheel 15 can accurately control the sliding speed of the steel pipe, ensuring that the steel pipe enters the subsequent inspection process at an appropriate speed, thereby ensuring the accuracy of the inspection. When the positioning wheel 15 slides to the end above the sliding platform 5, the electric slider 18 slides along the inner wall of the second section of the electric guide rail 19. At this time, the positioning wheel 15 will move downward and gradually break away from the tight fit with the steel pipe. After losing the constraint of the positioning wheel 15, the steel pipe will slide out along the bottom end of the sliding platform 5.

[0044] like Figures 5 to 7 As shown, one side of the two electric sliders 18 is fixedly connected to a connecting frame 22 , and the top of the connecting frame 22 is fixedly connected to both sides of the control panel 6 .

[0045] During operation: when the electric slider 18 drives the positioning wheel 15 to slide along the inner wall of the electric guide rail 19, the detection mechanism composed of the control panel 6 and the detector 7 will move along with the movement of the positioning wheel 15 through the connecting frame 22, so that the control panel 6 and the detector 7 can accurately move along with the sliding of the steel pipe, thereby achieving a comprehensive detection effect.

[0046] like Figures 5 to 7 As shown, the rolling assembly includes two gears 23, which are fixedly connected to the two ends of the rotating rod 16. The teeth of the gears 23 are engaged with a rack plate 24, and one end of the rack plate 24 is fixedly connected to a connecting platform 25, and the connecting platform 25 is respectively fixedly connected to one end of the electric guide rail 19.

[0047] During operation: when the blocking wheel 15 moves upward along the inclined surface of the sliding platform 5, the gears 23 fixed at both ends of the rotating rod 16 will mesh with the teeth of the rack plate 24. Due to the meshing action of the gear 23 and the rack plate 24, during the movement of the blocking wheel 15, the gear 23 can rotate, thereby driving the rotating rod 16 to rotate, and finally realizing the self-rotation of the blocking wheel 15. When the blocking wheel 15 rotates, it can generate rolling friction with the steel pipe that is tightly fitted on its outer wall. Compared with sliding friction, this rolling friction greatly reduces the friction resistance between the blocking wheel 15 and the steel pipe, so that the steel pipe can slide more smoothly along the inclined surface of the sliding platform 5 in a rolling form under the drive of the blocking wheel 15.

[0048] like Figure 1 As shown, a classification platform 29 is fixedly connected to the top of the detection platform 1. The classification platform 29 is C-shaped, and a classification component is provided between the classification platform 29 and the sliding platform 5.

[0049] During operation: When the steel pipe inspection is completed and it slides out from the bottom of the sliding platform 5, the inspection mechanism judges the concrete condition of the inner wall of the steel pipe and makes adaptive changes through the classification component. When the steel pipe is qualified, the classification component will prompt the steel pipe to slide to the top of the classification platform 29. When the inspection fails, the steel pipe will enter the inner wall of the classification platform 29, thereby reminding the staff to classify the steel pipe.

[0050] like Figure 1 As shown, the classification component includes an articulated seat 27, which is fixedly installed on the top of the inspection table 1. The inner wall of the articulated seat 27 is hinged with a material receiving table 26, and an arc-shaped telescopic rod 28 is fixedly connected between the bottom of the material receiving table 26 and one side of the articulated seat 27.

[0051] During operation: In the initial state, the top of the receiving platform 26 and the classification platform 29 are in a flush state. When the steel pipe passes the inspection, it slides directly along the plane of the receiving platform 26 to the upper surface of the classification platform 29. When the inspection fails, the arc-shaped telescopic rod 28 contracts, so that the receiving platform 26 is in an inclined state, and the steel pipe slides along the inclined surface of the receiving platform 26 to the inner wall of the classification platform 29.
