Description

Technical Field

[0001] This utility model relates to the field of concrete pole monitoring technology, and more specifically, to a device for monitoring surface cracks in recycled concrete poles. Background Technology

[0002] In power and railway construction, recycled concrete poles are widely used due to their superior mechanical properties, long service life, low cost, and minimal environmental pollution. However, cracks are prone to appear on the surface of the poles during production, transportation, and use. These cracks not only affect the aesthetics of the poles but may also seriously impact their mechanical properties and durability, and even lead to safety accidents. Therefore, it is necessary to monitor the cracks on the surface of recycled concrete poles during their use.

[0003] In practical use, since recycled concrete poles are usually conical, the monitoring device for surface gaps cannot be adjusted in time with changes in the surface diameter when it moves on the recycled concrete pole. This causes the monitoring device to shake when moving on the recycled concrete pole, which affects the monitoring effect of the visual camera on the surface gaps of the recycled concrete pole. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for monitoring surface cracks of recycled concrete poles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A device for monitoring surface cracks on recycled concrete utility poles includes two fixed rings. One end of each fixed ring is fixedly connected to a connecting plate 1, and the other end of each fixed ring is fixedly connected to a connecting plate 2. The two fixed rings, connecting plate 1, and connecting plate 2 cooperate to form a circular ring. Multiple supports are fixedly connected to the inner side of each fixed ring, and a rotating roller is rotatably connected to the inner side of each support. Multiple rubber strips are provided on the outer side of the rotating roller. Multiple brackets are fixedly connected to the top of each fixed ring, and a visual camera is fixedly connected to the inner side of each bracket. A bonding mechanism is provided on the outer side of connecting plate 1 and connecting plate 2. The bonding mechanism includes two... A connecting frame is placed on one side of the connecting plate 1. Both connecting plates 1 and 2 have through holes on their inner sides. An electric cylinder 1 is fixedly connected to the inner side of the connecting frame. A push plate is fixedly connected to the output end of the electric cylinder 1. The outer side of the push plate is slidably connected to the through hole on the inner side of the connecting plate 1. A threaded rod is fixedly connected to one side of the push plate. The threaded rod passes through the through holes on the inner sides of the connecting plates 1 and 2 in sequence, and its end extends to one side of the connecting plate 2. A positioning plate is fixedly connected to one side of the connecting plate 2. A nut is rotatably connected to the outer side of the positioning plate. The inner side of the nut is threadedly connected to the outer side of the threaded rod. A lifting and positioning mechanism is provided on the outer side of both fixing rings.

[0006] By adopting the above technical solution, the two fixed rings can be adjusted in distance on the surface of the recycled concrete pole by extending and retracting two electric cylinders, so that multiple rotating rollers and multiple transmission wheels on the inner side of the two fixed rings can fully contact the surface of the recycled concrete pole, ensuring that the two fixed rings move smoothly on the surface of the recycled concrete pole.

[0007] As a further description of the above technical solution: the lifting and positioning mechanism includes a first fixed frame disposed on the outside of the two fixed rings. A dual-output shaft servo motor is fixedly connected to the bottom of the first fixed frame. A transmission wheel is fixedly connected to each of the two output ends of the dual-output shaft servo motor. The surface of the transmission wheel is set as an inclined surface that fits the surface of the pole. Two second fixed frames are fixedly connected to the outside of the two fixed rings. The two second fixed frames are symmetrically distributed on the outside of the fixed rings. An electric cylinder is fixedly connected to the bottom of the second fixed frame. An arc-shaped plate is fixedly connected to the output end of the second electric cylinder. Multiple anti-slip strips are fixedly connected to one side of the arc-shaped plate. The cross-section of the anti-slip strips is arc-shaped.

[0008] By adopting the above technical solution: the inclined surface of the transmission wheel can be used to fit with the surface of the recycled concrete pole, and with the transmission of the dual-output shaft servo motor, a stable driving force can be obtained. Combined with the pushing of multiple electric cylinders and two pairs of arc plates and anti-slip strips, the positions of the two fixed rings can be quickly positioned.

[0009] The technical effects and advantages of this utility model are as follows: 1. By setting up a bonding mechanism, compared with the existing technology, the clamping force can be adjusted in time by using two electric cylinders and a fixed ring to move in opposite directions. This ensures that the friction between the transmission wheel and the pole surface is always within an optimal range, avoiding slippage and jamming. This allows the vision camera to rise and fall at a constant speed, avoiding sudden stops, shaking or crawling, ensuring the quality of image data acquired by the vision camera, and also being able to cope with the tapered structure of recycled concrete poles, improving adaptability and versatility. 2. By setting up a lifting and positioning mechanism, compared with the existing technology, multiple inclined transmission wheels can effectively perform friction transmission on the recycled concrete pole. Combined with the opposing clamping of multiple arc plates and anti-slip strips, the two fixed rings and multiple vision cameras can be started and stopped, ensuring the accuracy of the vision cameras in monitoring the surface gaps of the recycled concrete pole.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The embodiments disclosed in this application are as follows: Figures 1-8The device for monitoring surface cracks in recycled concrete poles includes two fixed rings 1. One end of each fixed ring 1 is fixedly connected to a connecting plate 1, and the other end of each fixed ring 1 is fixedly connected to a connecting plate 2. The two fixed rings 1, connecting plate 1, and connecting plate 2 form a ring. Multiple supports 4 are fixedly connected to the inner side of each fixed ring 1. A rotating roller 5 is rotatably connected to the inner side of each support 4. Multiple rubber strips are provided on the outer side of each rotating roller 5. Multiple brackets 12 are fixedly connected to the top of each fixed ring 1. A visual camera 13 is fixedly connected to the inner side of each bracket 12. A bonding mechanism is provided on the outer side of connecting plate 1 2 and connecting plate 2 3. The bonding mechanism includes two connecting frames 6 located on one side of connecting plate 1 2. Through holes are provided on the inner side of both connecting plate 1 2 and connecting plate 2 3. An electric cylinder 1 7 is fixedly connected to the inner side of the connecting frame 6. A push plate 8 is fixedly connected to the output end of the electric cylinder 1 7. The outer side of the push plate 8 is slidably connected to the inner through hole of the connecting plate 2. A threaded rod 9 is fixedly connected to one side of the push plate 8. The threaded rod 9 passes through the through holes inside the connecting plate 2 and the connecting plate 3 in sequence, and its end extends to one side of the connecting plate 3. A positioning plate 10 is fixedly connected to one side of the connecting plate 3. A nut 11 is rotatably connected to the outer side of the positioning plate 10. The inner side of the nut 11 is threadedly connected to the outer side of the threaded rod 9. A lifting and positioning mechanism is provided on the outer side of the two fixing rings 1. The output end is driven by two electric cylinders 7, so that the two fixing rings 1 can adjust the opposing distance in time according to the change of the diameter of the recycled concrete pole surface. This allows the multiple rotating rollers 5 and the transmission wheel 16 to maintain good contact with the surface of the recycled concrete pole, so that the two fixing rings 1 can drive the vision camera 13 to move smoothly up and down on the surface of the recycled concrete pole, thereby improving the applicability of the monitoring device.

[0021] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the lifting and positioning mechanism includes a first fixed frame 14 disposed outside the two fixed rings 1. A dual-axis servo motor 15 is fixedly connected to the bottom of the first fixed frame 14. A transmission wheel 16 is fixedly connected to each of the two output ends of the dual-axis servo motor 15. The surface of the transmission wheel 16 is set as an inclined surface that fits against the surface of the pole. Two second fixed frames 17 are fixedly connected to the outside of the two fixed rings 1. The two second fixed frames 17 are symmetrically distributed outside the fixed rings 1. An electric cylinder 18 is fixedly connected to the bottom of the second fixed frame 17. An arc-shaped plate 19 is fixedly connected to the output end of the electric cylinder 18. One side of the arc-shaped plate 19 is fixed. Multiple anti-slip strips 20 are connected, and the anti-slip strips 20 have an arc-shaped cross-section. Multiple electric cylinders 18 push the arc plate 19 and the anti-slip strips 20 to fit against the surface of the recycled concrete pole, so as to realize the timely positioning of the two fixing rings 1 on the surface of the recycled concrete pole. This ensures that multiple vision cameras 13 can further monitor the gap stably. Two dual-axis servo motors 15 drive the corresponding two transmission wheels 16 to perform friction transmission with the surface of the recycled concrete pole, so that the two fixing rings 1 can drive the multiple vision cameras 13 to move up and down along the surface of the recycled concrete pole.

[0022] The working principle of this utility model is as follows: When monitoring the gaps on the surface of the recycled concrete pole after installation and use, the staff first moves the two fixing rings 1 to the two sides of the recycled concrete pole respectively, and brings the connecting plate 2 on one side of the two fixing rings 1 close to the corresponding connecting plate 3 on the other side. The threaded rod 9 on one side of the connecting plate 2 passes through the through hole inside the connecting plate 3. Then, the two nuts 11 are rotated so that the two nuts 11 can be threadedly connected to the threaded rod 9. The two fixing rings 1, the connecting plate 2 and the connecting plate 3 form a ring around the recycled concrete pole through the threaded rod 9 and the nuts 11. This causes the multiple rotating rollers 5 inside the two fixing rings 1 to fit against the surface of the recycled concrete pole, so that the fixing rings 1 and the surface of the recycled concrete pole have a certain rolling support force. By using an external PLC controller, two dual-axis servo motors 15 are started to drive the transmission wheels 16 at their two output ends to rub against the surface of the recycled concrete pole. The inclined surfaces of the transmission wheels 16 are fully in contact with the surface of the recycled concrete pole, so that the two fixed rings 1 can move upward along the recycled concrete pole under the friction transmission of the corresponding multiple transmission wheels 16. As the two fixed rings 1 move upward along the recycled concrete pole, driving multiple nuts 11 and brackets 12, and monitor the gaps on its surface, the electric cylinders 7 on one side of the two connecting plates 2 along the conical surface of the recycled concrete pole will drive the output end to retract, thereby driving the two fixed rings 1 to move closer to each other. Conversely, as the two fixed rings 1 descend on the surface of the recycled concrete pole, they will drive the output end to extend, so that the multiple rotating rollers 5 and multiple transmission wheels 16 inside the two fixed rings 1 can always maintain effective contact with the surface of the recycled concrete pole. After multiple visual cameras 13 detect the gaps on the surface of the recycled concrete pole, multiple electric cylinders 18 are activated to push the arc plate 19 and multiple anti-slip strips 20 to form a pressing force against the surface of the recycled concrete pole, so that the two fixing rings 1 can be fixed at a suitable height on the surface of the recycled concrete pole. Finally, the corresponding visual cameras 13 accurately monitor the gaps, thus completing the gap monitoring of the surface of the recycled concrete pole.
