Description

Technical Field

[0001] This utility model relates to the field of concrete pole testing technology, and in particular to a rebar detector for concrete poles. Background Technology

[0002] As a crucial component of infrastructure such as power, communication, and municipal engineering, the integrity of the internal reinforcing steel, the degree of corrosion, and the thickness of the protective layer directly determine the structural safety of concrete poles. With the advancement of urbanization, the application scenarios of concrete poles are becoming increasingly complex, leading to a significant increase in the demand for inspection of high-altitude, large-diameter, or irregularly shaped concrete poles.

[0003] In the prior art, utility model patent CN220542932U discloses a concrete reinforcement detector, which includes a detector body, a detection probe, two protective plates, two baffles, a connecting line, a fixing column, and a limiting component. The two protective plates are installed side-by-side on the bottom surface of the detector body. Each protective plate has a through groove on its adjacent end face, and each protective plate has a sliding groove that communicates with each through groove. The fixing column is installed on the bottom surface of the detector body, arranged side-by-side with the two protective plates. The limiting component is detachably installed on the bottom surface of the fixing column. However, when the above detector is used to inspect tall concrete columns, it requires manual climbing of the concrete pole, posing a risk of fall from height and resulting in poor safety during high-altitude inspections.

[0025] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. The present invention will now be further described in conjunction with the accompanying drawings and embodiments:

[0026] Please see Figure 1-5A rebar detector for concrete utility poles includes a fixing device 4, a driving device 5, and a detection device 8. The detection device 8 is mounted on the fixing device 4. The fixing device 4 includes an annular fixing part, which is an openable and closable annular structure. The driving device 5 includes a second slide 51, a climbing wheel 53, and a motor 57. The second slide 51 is connected to the fixing device 4. The climbing wheel 53 is rotatably connected to one end of the second slide 51 near the inside of the fixing device 4, and the axis of the climbing wheel 53 is perpendicular to the axis of the annular fixing part. The motor 57 is connected to the climbing wheel 53.

[0027] The annular fixing part can fix the rebar detector coaxially with the concrete pole, the drive device 5 can drive the equipment to climb along the axial direction of the concrete pole, and the detection device 8 can detect the state of the rebar inside the concrete pole.

[0028] By employing an openable and closable annular fixing part, the concrete pole can be securely embraced; the drive device 5 drives the climbing wheel 53 to rotate through the motor 57, enabling autonomous high-altitude movement without manual climbing and eliminating the risk of fall; the climbing wheel 53 is rotatably connected to the second slide 51 and its axis is perpendicular to the axis of the concrete pole, fitting tightly with the concrete pole to ensure climbing stability, adapting to high-altitude operation scenarios and improving inspection safety and efficiency.

[0029] In some embodiments, the detection device 8 is connected to one end of the connecting line 9, and the other end of the connecting line 9 is connected to the controller 10.

[0030] In some embodiments, the annular fixing part includes a first fixing ring 2 and a second fixing ring 7, both of which are semi-annular structures, and the first fixing ring 2 and the second fixing ring 7 are connected to form an annular structure.

[0031] The first fixing ring 2 and the second fixing ring 7 are both semi-circular and can be connected to form a ring. They adopt a split design, which makes it easy to open and close the installation at any position on the concrete pole. The semi-circular structure fits the curved surface of the concrete pole and can form a stable ring after connection, ensuring that the equipment is coaxial with the concrete pole and avoiding deviation during testing.

[0032] In some embodiments, the fixing device 4 further includes a first clamp 1 and a second clamp 6. The first clamp 1 is embedded in one end of the first fixing ring 2 and the second fixing ring 7, and the second clamp 6 is embedded in the other end of the first fixing ring 2 and the second fixing ring 7. By tightening the first clamp 1 and the second clamp 6, the first fixing ring 2 and the second fixing ring 7 are circumferentially fixed to the concrete pole.

[0033] The first clamp 1 is embedded in one end of the first fixing ring 2 and the second fixing ring 7, and the second clamp 6 is embedded in the other end of the first fixing ring 2 and the second fixing ring 7. By tightening, the semi-circular first fixing ring 2 and the second fixing ring 7 can firmly hug the concrete pole, ensuring that the equipment is coaxial with the concrete pole and preventing displacement during climbing or inspection. The clamp embedded design makes the fixation more stable. Disassembly is simple; just loosen the first clamp 1 and the second clamp 6.

[0034] In some embodiments, the fixing device 4 further includes a support assembly and a second electric push rod 44, one end of the second electric push rod 44 being connected to the annular fixing part, and the other end of the second electric push rod 44 being connected to the support assembly. The support assembly is fixedly connected to the second slide table 51, and the second slide table 51 is slidably connected to the annular fixing part.

[0035] The second electric push rod 44 connects the annular fixing part and the support assembly. The extension and retraction of the second electric push rod 44 can drive the support assembly and the second slide table 51 to move, thereby adjusting the fit between the climbing wheel 53 and the surface of the concrete pole. It can adapt to uneven conditions such as depressions and protrusions on the surface of the concrete pole, ensuring stable friction during climbing. At the same time, it can be adjusted in real time according to the change of the diameter of the concrete pole, adapting to concrete poles of different thicknesses, solving the problem that traditional testing instruments cannot flexibly adapt to changes in the surface and diameter of concrete poles.

[0036] In some embodiments, the fixing device 4 further includes a second guide rail 36, one end of which is fixedly connected to the support component, and the other end of which passes through the annular fixing part, and the second guide rail 36 is slidably connected to the annular fixing part.

[0037] One end of the second guide rail 36 is fixed to the support component, and the other end is connected to the ring-shaped fixing part and slidably. This provides a stable guide for the support component to move the second slide table 51, ensuring that the climbing wheel 53 or the detection-related structure does not deviate during the adjustment process. The support component moves more smoothly, avoiding jamming that affects the adjustment accuracy. At the same time, it enhances the overall connection strength and improves the stability of the equipment during climbing and detection.

[0038] In some embodiments, the support assembly includes a fourth guide rail 41, a fifth guide rail 43, and a second support frame 42. The second electric push rod 44 is connected to the second support frame 42, and the second guide rail 36 is fixedly connected to the second support frame 42. The fourth guide rail 41 and the fifth guide rail 43 are respectively installed at the upper and lower ends of the second support frame 42, and both the fourth guide rail 41 and the fifth guide rail 43 are fixedly connected to the second slide table 51.

[0039] When climbing is required, the second electric push rod 44 is activated to retract, which drives the fourth guide rail 41 and the fifth guide rail 43 to move inward through the second support frame 42, pushing the second slide table 51 to slide along the inner side of the first fixed ring 2, so that the climbing wheel 53 is in close contact with the surface of the concrete pole.

[0040] The second support frame 42 is positioned at the upper and lower ends by the fourth guide rail 41 and the fifth guide rail 43 and connected to the second slide table 51 to form a symmetrical and stable support structure. This improves the force balance of the second slide table 51 and prevents it from tilting during climbing or adjustment. The second support frame 42 serves as the connecting core and also fixes the second guide rail 36 and the second electric push rod 44 to ensure precise power transmission and guiding linkage, making the climbing wheel 53 more stable and enhancing the stability of equipment operation.

[0041] In some embodiments, the drive device 5 further includes a gear set and a pulley set, the gear set being connected to the climbing wheel 53, the pulley set being connected to the gear set, and the motor 57 being connected to the pulley set.

[0042] The motor 57 is driven to the gear set through the pulley set, which in turn drives the climbing wheel 53 to rotate. The two-stage transmission improves the stability of power transmission, avoids the impact damage caused by direct drive of the motor 57, and makes the climbing speed stable and controllable, which is suitable for high-altitude climbing needs.

[0043] In some embodiments, the gear set includes a first gear 52 and a second gear 54, the first gear 52 being coaxially fixed with the climbing wheel 53, and the second gear 54 being meshed with the first gear 52; the pulley set includes a first pulley 55 and a second pulley 56, the first pulley 55 being coaxially fixed with the second gear 54, the second pulley 56 being fixed with the output shaft of the motor 57, the first pulley 55 and the second pulley 56 being connected by a belt drive, and the motor 57 being fixed on the second slide table 51.

[0044] The first gear 52 is coaxially fixed with the climbing wheel 53, the second gear 54 meshes with the first gear 52 on both sides, the first pulley 55 is coaxially fixed with the second gear 54, the second pulley 56 is fixed with the output shaft of the motor 57, and the first pulley 55 and the second pulley 56 are connected by belt drive, which ensures transmission accuracy and realizes flexible power transmission, reducing vibration.

[0045] In some embodiments, an adjustment device 3 is also included, which is mounted on the fixing device 4, and the detection device 8 is connected to the adjustment device 3.

[0046] By setting the adjustment device 3, the distance between the detection device 8 and the surface of the concrete pole can be adjusted. For tapered concrete poles or poles with indentations on the surface, it can automatically adapt to changes in the shape of the pole and keep the distance between the detection device 8 and the surface of the pole constant, ensuring detection accuracy. The distance adjustment can be completed without manual intervention. Combined with the automatic climbing of the fixing device 4 and the driving device 5, the detection efficiency is further improved. This solves the problem that traditional detection instruments cannot adapt to irregular poles and require manual distance adjustment, and adapts to the detection needs of complex scenarios.

[0047] In some embodiments, the adjustment device 3 includes a first electric push rod 33 and a limiting component. The fixed end of the first electric push rod 33 is fixedly connected to the fixing device 4, and the movable end of the first electric push rod 33 is connected to the limiting component. The detection device 8 is installed inside the limiting component.

[0048] The first electric push rod 33 is connected to the fixed device 4 at its fixed end, and to the detection device 8 at its movable end via a limiting component. The first electric push rod 33 can precisely control the position adjustment of the detection device 8, with a rapid response and high adjustment accuracy. The limiting component can firmly fix the detection device 8, preventing the results from being affected by equipment shaking during detection. For cases where the surface of the concrete pole is uneven or the diameter varies, the detection distance can be adjusted in real time via the first electric push rod 33 to maintain detection stability without manual intervention. Combined with automated climbing, this improves detection efficiency and solves the problems of inconvenient and inaccurate traditional detection distance adjustment.

[0049] In some embodiments, the limiting component includes a limiting frame 37, a trapezoidal slider 38, and a first slide table 35. The limiting frame 37 is fixedly connected to the movable end of the first electric push rod 33. The trapezoidal slider 38 is fixed to the first slide table 35. The limiting frame 37 and the trapezoidal slider 38 are engaged. The limiting frame 37 and the first slide table 35 form a limiting groove. The detection device 8 is installed in the limiting groove.

[0050] By engaging the limit frame 37 with the trapezoidal slider 38, the power of the first electric push rod 33 is stably transmitted to the first slide table 35. The trapezoidal structure also limits radial offset, improving adjustment accuracy. The limit groove formed by the limit frame 37 and the first slide table 35 can securely fix the detection device 8, preventing it from loosening during climbing or adjustment, and ensuring detection accuracy.

[0051] In some embodiments, the adjustment device 3 further includes a first support frame 32 and a first guide rail 34. One end of the first support frame 32 is connected to the fixing device 4, and the other end of the first support frame 32 is fixedly connected to the first electric push rod 33. The first guide rail 34 is disposed on the first support frame 32 and is radially disposed along the annular fixing portion. The first guide rail 34 is slidably connected to the first slide table 35.

[0052] The first support frame 32 connects the fixing device 4 and the first electric push rod 33 to form a stable support structure. The first guide rail 34 is radially arranged along the annular fixing part and slidably connected to the first slide table 35, providing precise guidance for the adjustment of the detection device 8 and avoiding deviation. The radial guide design is adapted to the radial distance adjustment requirements of the concrete pole, making the movement of the detection device 8 more stable and improving the adjustment accuracy and structural stability.

[0053] In some embodiments, the first support frame 32 is mounted on the support assembly, and the first support frame 32 and the support assembly are fixedly connected by bolts 31.

[0054] The first support frame 32 is fixed to the support assembly by bolts 31, which is firm and easy to disassemble and assemble, facilitating equipment maintenance or component replacement and adapting to the assembly requirements of different specifications of testing devices 8. At the same time, it can also ensure that the first support frame 32 moves synchronously with the support assembly. When the support assembly is adjusted according to the change of the diameter of the concrete pole, it can drive the adjustment device 3 to maintain a constant distance between the testing device 8 and the surface of the concrete pole.

[0055] The working principle of this utility model:

[0056] Before testing, the first fixing ring 2 and the second fixing ring 7 are first put on the outside of the concrete pole. The first clamp 1 and the second clamp 6 are embedded in the front and rear ends of the fixing ring to form a ring-shaped fixation, ensuring that the equipment is coaxial with the concrete pole. Then, the adjusting device 3 is connected to the fifth guide rail 43 of the fixing device 4 by bolt 31. The testing device 8 is installed in the first slide 35. The first slide 35 is fixed by the trapezoidal slider 38 and the limiting frame 37.

[0057] When climbing is required, the second electric push rod 44 is activated to retract, which drives the fourth guide rail 41 and the fifth guide rail 43 to move inward through the second support frame 42. This pushes the second slide table 51 to slide along the inner side of the first fixed ring 2, so that the climbing wheel 53 is in close contact with the surface of the concrete pole. Then, the output shaft of the motor 57 drives the second pulley 56 to rotate, which drives the first pulley 55 to rotate through the belt drive. This drives the second gear 54 to mesh with the first gears 52 on both sides, so that the climbing wheel 53 rotates synchronously. At the same time, the first gear 52 is coaxially fixed with the climbing wheel 53. The fixed ring moves along the axial direction of the concrete pole by relying on friction. The two drive devices 5 operate synchronously to avoid deviation.

[0058] When it is necessary to adjust the distance between the detection device 8 and the surface of the cement column, the first electric push rod 33 is activated. The front end of the push rod drives the limiting frame 37 to move along the first guide rail 34. The first slide table 35 is engaged through the trapezoidal slider 38, and the first slide table 35 is pushed to slide on the first guide rail 34 to realize the radial position adjustment of the detection device 8. When climbing to the area where the diameter of the concrete pole changes, the fifth guide rail 43 of the fixing device 4 drives the bolt 31 to move synchronously through the first support frame 32, so that the first electric push rod 33 and the first slide table 35 are linked for adjustment to maintain a constant distance between the detection device 8 and the surface of the pole.

[0059] The main functions of this utility model are:

[0060] This invention achieves stable installation through an openable and closable annular fixing part, adapting to concrete poles of different diameters and facilitating easy assembly and disassembly; the drive device, through gear and pulley linkage, enables stable high-altitude movement without manual climbing, eliminating safety hazards; the adjustment device, guided by a first electric push rod and a first guide rail, automatically adapts to irregularly shaped poles such as tapered and concave poles, maintaining a constant detection distance; through the coordinated operation of the fixing device, drive device, adjustment device, and detection device, it balances automated operation, structural stability, and scene adaptability, significantly improving detection efficiency and accuracy, and comprehensively solving the problems of traditional detection relying on manual labor, poor adaptability, and low safety.
