Detailed Implementation

[0023] 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.

[0024] like Figures 1-4 As shown, a rebar sleeve crack detection device includes a detection device body 1; a chain conveyor belt body 11 is mounted on the top of the detection device body 1; a smart camera 12 is fixedly connected to the top of the detection device body 1; multiple sets of limiting shaft bodies 13 are rotatably connected to the outer side of the chain conveyor belt body 11; teeth 14 are fixedly connected to the bottom outer side of the smart camera 12; a rack 15 is fixedly connected to the top of the chain conveyor belt body 11 near the teeth 14; the outer side of the rack 15 meshes with the teeth 14; during operation, the rebar sleeve to be detected is sleeved on the outer side of the limiting shaft body 13, and then the chain conveyor belt body 11 is driven to rotate, causing the rebar sleeve to be placed on the smart camera 12, which then aligns the sleeve with the camera. The sleeve is observed during the process. Simultaneously, when the chain conveyor body 11 moves the limiting shaft body 13 closer to the smart camera 12, the teeth 14 on the outer side of the limiting shaft body 13 will mesh with the rack 15 on the top of the chain conveyor body 11, causing the limiting shaft body 13 to rotate while moving. In the case of visual inspection of the rebar sleeve, this step requires continuous rotation of the sleeve to observe whether cracks appear around it, which increases the inspection steps and time costs. Therefore, by using the teeth 14 to move the limiting shaft body 13, which is rotatably connected to the chain conveyor body 11, the sleeve can rotate while moving, reducing the inspection steps and lowering the time cost.

[0025] like Figures 1-3As shown, the limiting shaft body 13 is internally connected with a connecting column 2; the connecting column 2 is externally connected with a plurality of telescopic columns 21; the telescopic column 21 is externally installed with a reset spring 22; the telescopic column 21 is externally connected with a supporting clamping plate 23; the supporting clamping plate 23 is internally slid in the limiting shaft body 13; when the sleeve is installed outside the limiting shaft body 13, the sleeve internally extrudes the supporting clamping plate 23, the connecting column 2 fixes the reset spring 22 and the telescopic column 21, and the supporting clamping plate 23 slides internally in the limiting shaft body 13, extruding the telescopic column 21 and the reset spring 22; when the installation is completed, the reset spring 22 rebounds to clamp the sleeve; when the sleeve is installed outside the limiting shaft body 13, the extrusion of the sleeve by the supporting clamping plate 23 makes the intelligent camera 12 more stable when observing the sleeve, and further improves the working efficiency of the intelligent camera 12.

[0026] As shown in the Figure 3 supporting clamping plate 23, the sleeve extrudes the rotating shaft 31, the rotating shaft 31 rotates in the hollow groove 3, and the sleeve enters the outside of the limiting shaft body 13 more smoothly; through the use of the rotating shaft 31 and the hollow groove 3, when the sleeve is installed outside the limiting shaft body 13, the rolling of the rotating shaft 31 improves the convenience and efficiency of installation, reduces the damage to the inner wall of the sleeve caused by the inner wall of the supporting clamping plate 23, and further increases the service life of the supporting clamping plate 23 of the device.

[0027] As shown in the Figures 1-2 the detection device body 1 is internally provided with a storage tank 4; the detection device body 1 is externally provided with an inlet 41 on one side; the inlet 41 is in communication with the storage tank 4; the detection device body 1 is externally provided with an outlet 42 at the bottom; the outlet 42 is in communication with the storage tank 4; when the sleeve is detected, it is located at the bottom of the chain conveyor body 11 due to the rotation of the chain conveyor body 11; when the sleeve enters the bottom of the chain conveyor body 11, it falls due to its own weight, improves the inlet 41 into the storage tank 4, and then is taken out from the outlet 42; this step collects the falling sleeve through the storage tank 4, increases the collection of the detected sleeve, and further improves the working efficiency.

[0028] As shown in the Figures 3-4As shown, a limiting ring 5 is fixedly connected to the outside of the limiting shaft body 13; the limiting ring 5 is located above the tooth 14; during operation, when the sleeve is installed on the outside of the limiting shaft body 13, the limiting ring 5 will limit the bottom of the sleeve. This step limits the sleeve by limiting the sleeve through the limiting ring 5, reducing the situation where the bottom of the sleeve touches the tooth 14 when the sleeve is installed, affecting the meshing with the rack 15, and improving the stability of the device.

[0029] like Figure 2 As shown, the storage box 4 is provided with an inclined plate 6 on the inner side; when the sleeve after the test is completed enters the storage box 4 during operation, the inclined plate 6 rolls the sleeve directly out of the storage box 4, which improves the speed of sleeve removal and improves work efficiency.

[0030] like Figure 1 As shown, an illumination device body 7 is provided on the outer side of the main body 1 of the detection device, close to the smart camera 12. When the smart camera 12 detects the sleeve during operation, the illumination device body 7 is turned on to illuminate the sleeve, and the better brightness increases the accuracy of the detection by the smart camera 12.

[0031] The working principle is that the steel sleeve to be detected is sleeved outside the limiting shaft body 13, then the chain conveying belt body 11 is driven to start rotating, the steel sleeve is observed by the intelligent camera 12, and when the chain conveying belt body 11 drives the limiting shaft body 13 to approach the intelligent camera 12, the teeth 14 outside the limiting shaft body 13 are meshed with the rack 15 at the top of the chain conveying belt body 11, so that the limiting shaft body 13 drives the sleeve to rotate while moving, and the sleeve is continuously rotated for observation when the steel sleeve is detected by visual detection, which increases the detection steps and improves the time cost, so the limiting shaft body 13 connected with the chain conveying belt body 11 is driven by the teeth 14 to rotate, so that the sleeve rotates while moving, which reduces the detection steps and reduces the time cost. When the sleeve is installed outside the limiting shaft body 13, the inside of the sleeve will extrude the supporting clamping plate 23, the connecting column 2 fixes the reset spring 22 and the telescopic column 21, so that the supporting clamping plate 23 slides to the inside of the limiting shaft body 13, extruding the telescopic column 21 and the reset spring 22, and the reset spring 22 rebounds to clamp the sleeve after installation. When the sleeve is installed outside the limiting shaft body 13, the extrusion of the sleeve by the supporting clamping plate 23 makes the observation of the sleeve by the intelligent camera 12 more stable, further improving the working efficiency of the intelligent camera 12. When the sleeve is limited by the supporting clamping plate 23, the sleeve will drive the rotating shaft 31, and the rotating shaft 31 rotates in the empty slot 3, so that the sleeve enters the outside of the limiting shaft body 13 more smoothly. Through the use of the rotating shaft 31 and the empty slot 3, when the sleeve is installed outside the limiting shaft body 13, the rolling of the rotating shaft 31 improves the convenience and efficiency of installation, while reducing the damage to the inner wall of the sleeve caused by the inner wall of the supporting clamping plate 23, further increasing the service life of the supporting clamping plate 23 of the device. When the sleeve is detected, it will be located at the bottom of the chain conveying belt body 11 due to its own weight, and will fall into the storage box 4 through the feeding port 41 and then be taken out from the discharging port 42. This step collects the falling sleeve through the storage box 4, increases the collection of the detected sleeve, and further improves the working efficiency. When the sleeve is installed outside the limiting shaft body 13, the limiting ring 5 limits the bottom of the sleeve. This step limits the sleeve by the limiting ring 5, reduces the situation that the bottom of the sleeve touches the teeth 14 when the sleeve is installed, affects the meshing with the rack 15, and improves the stability of the device. When the detected sleeve enters the storage box 4, the sleeve is directly rolled out of the storage box 4 through the inclined plate 6, improving the speed of taking out the sleeve and improving the working efficiency. When the intelligent camera 12 detects the sleeve, the lighting device body 7 is turned on to illuminate the sleeve.Better brightness increases the accuracy of the detection of the smart camera 12.
