Description

Technical Field

[0001] This utility model relates to the field of aluminum pole surface inspection technology, and in particular to a device for detecting surface defects on aluminum poles used for overhead conductors. Background Technology

[0002] Aluminum poles for overhead power transmission are cylindrical blanks used to produce overhead power transmission lines. Because there are depressions or protrusions on the surface of the aluminum poles, it is necessary to inspect for surface defects.

[0003] A related technology, Chinese Patent No. CN219567148U, discloses a wire pressing and arranging device for an aluminum rod take-up machine. This device includes a base, a detection frame fixedly connected to the base, through which the aluminum rod body passes. Several fixed frames are mounted on the detection frame, and ball bearings are mounted on the fixed frames for contact with the aluminum rod body. Connecting blocks are rotatably connected to both sides of the ball bearings via rotating shafts. The connecting blocks are slidably connected to both sides of the fixed frames, and contact blocks are fixedly connected to both sides of each connecting block. Sensors are installed within the fixed frames, located on both sides of the connecting blocks. A limit slide plate is fixedly connected to the side of the connecting block away from the ball bearings, and the limit slide plate is slidably connected to the inside of the fixed frames. A spring connects the limit slide plate to the fixed frames. When the aluminum rod body is inserted into the detection frame, the ball bearings contact the aluminum rod body, and the contact blocks separate from the sensors. During the movement of the aluminum rod body, if there is a large depression or protrusion on the surface of the aluminum rod body, the connecting block will cause the contact block to contact the sensor, triggering an alarm light to alert the operator.

[0004] In the process of developing this application, it was found that the technology has at least the following problems: due to the limited internal space of the testing frame and the volume of the fixed frame, the number of balls that can be installed in the testing frame is limited, and there are gaps between adjacent balls. When defects on the surface of the aluminum rod body pass through the gaps between adjacent balls, there will be missed detection, which will affect the quality of surface defect detection of the aluminum rod body. Utility Model Content

[0005] In order to reduce the number of missed defects on the surface of aluminum poles and improve the quality of surface defect detection, this application provides a surface defect detection device for aluminum poles used in overhead conductors.

[0006] The surface defect detection device for aluminum poles used in overhead conductors provided in this application adopts the following technical solution: A surface defect detection device for overhead conductor aluminum poles includes a base, a detection ring and a warning light disposed above the base, a plurality of ball bearings disposed inside the detection ring, a connecting component disposed between the ball bearings and the detection ring, the connecting component being used to connect the ball bearings and the detection ring, a triggering component disposed within the connecting component, the triggering component being used to trigger the warning light, a set of brackets fixedly disposed on the base, an adjusting ring seat being disposed through the brackets, the brackets and the adjusting ring seat being rotatably connected, the opposite surface of the adjusting ring seat being fixedly connected to the detection ring, and a driving component disposed on the base, the driving component being used to drive the adjusting ring seat to rotate synchronously.

[0007] By adopting the above technical solution, when performing surface defect detection on the aluminum rod body, the aluminum rod body is inserted into multiple detection rings. Then, the driving component is used to make the adjusting ring seat drive the detection ring to rotate, adjusting the distribution position of the balls on the outer ring wall of the aluminum rod body. This ensures that the balls are staggered on the outer ring wall of the aluminum rod body, reducing the possibility of missed detection of surface defects on the aluminum rod body. Afterwards, the connecting component is used to bring the balls into contact with the aluminum rod body. At this time, the triggering component does not trigger the warning light. During the movement of the aluminum rod body, if there is a large depression or protrusion on the surface of the aluminum rod body, the balls move radially along the detection ring, causing the triggering component to trigger the warning light to alarm, reminding the staff. This reduces the possibility of missed detection due to surface defects on the aluminum rod body and missed balls, thus improving the quality of surface defect detection on the aluminum rod body.

[0008] Preferably, the drive assembly includes a set of drive gears and a set of drive racks, wherein one drive gear is sleeved on one of the adjusting ring seats, and the other drive gear is sleeved on another adjusting ring seat. The drive gears are fixedly connected to the adjusting ring seats, and the drive racks are slidably disposed on the base, wherein one drive rack meshes with one of the drive gears, and the other drive rack meshes with the other drive gear.

[0009] By adopting the above technical solution, the drive rack slides synchronously, driving the drive gear to rotate synchronously, and the synchronous rotation of the drive gear drives the adjusting ring seat to rotate synchronously.

[0010] Preferably, the drive assembly further includes a drive slide, which is slidably mounted on the base, and the drive rack is fixedly connected to the drive slide.

[0011] By adopting the above technical solution, the drive slide moves and drives the drive rack to slide synchronously.

[0012] Preferably, the drive assembly further includes a drive screw and a drive slider. A drive groove is formed on the base, the drive slider is slidably disposed in the drive groove, the drive slider is fixedly connected to the drive slide block, the drive screw is rotatably disposed in the drive groove, and the drive groove block is threadedly connected to the drive screw.

[0013] By adopting the above technical solution, rotating the drive screw drives the drive slider to move along the drive groove, and the movement of the drive slider drives the drive slide block to move.

[0014] Preferably, the connecting assembly includes a connecting sleeve, a connecting slider, a connecting slide rod, and a connecting spring. The connecting sleeve is connected to the inner wall of the detection ring. The connecting slider is slidably disposed inside the connecting sleeve. One end of the connecting spring is connected to the inner wall of the connecting sleeve, and the other end of the connecting spring is connected to the connecting slider. The end of the connecting slider away from the connecting spring is connected to one end of the connecting slider rod. The other end of the connecting slide rod passes through the connecting sleeve and is slidably connected to the connecting sleeve. The end of the connecting slide rod located outside the connecting sleeve is connected to a ball bearing. The triggering assembly is disposed between the inner wall of the connecting sleeve and the outer wall of the connecting slider.

[0015] By adopting the above technical solution, when the aluminum rod body is inserted into the detection ring, the aluminum rod body is inserted between the balls. Under the action of the connecting spring, the balls are in contact with the outer wall of the aluminum rod body. When there is a large depression or protrusion on the surface of the aluminum rod body, the balls move in the radial direction of the detection ring, and then the balls drive the connecting slide rod to move. The connecting slide rod drives the connecting slider to move, causing the triggering component to trigger the warning light.

[0016] Preferably, the outer wall of the ball bearing is provided with a plurality of spheres.

[0017] By adopting the above technical solution, the ball transforms the sliding friction between the ball and the aluminum rod body into rolling friction, thereby reducing the frictional force between the ball and the aluminum rod body.

[0018] Preferably, an electric cylinder is provided between the connecting sleeve and the detection ring.

[0019] By adopting the above technical solution, the distance between the connecting sleeve and the inner wall of the detection ring is adjusted by extending and retracting the output shaft of the electric cylinder. This ensures that the warning light is not triggered when the ball contacts a defect-free part of the aluminum rod body surface.

[0020] Preferably, the triggering component includes a set of contact blocks and a set of sensors. The sensors are fixedly disposed inside the connecting sleeve and are arranged opposite to each other. The connecting slider is located between the opposite surfaces of the sensors. One side of the connecting slider is connected to one of the contact blocks, and the other side of the connecting slider is connected to another contact block. One of the contact blocks is arranged opposite to one of the sensors, and the other contact block is arranged opposite to the other sensor.

[0021] By adopting the above technical solution, when there is a large depression or protrusion on the surface of the aluminum rod body, the ball moves along the radial direction of the detection ring, and then the ball drives the connecting slide rod to move, the connecting slide rod drives the connecting slider to move, the connecting slider moves the contact block to move, and when the contact block contacts the sensor, the warning light is triggered.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a base, detection ring, warning light, ball bearings, connecting components, triggering components, bracket, adjusting ring seat, and driving components, the ball bearings are staggered on the outer ring wall of the aluminum rod body, reducing the chance of missed detection due to surface defects of the aluminum rod body and missing ball bearings, thereby improving the detection quality of surface defects of the aluminum rod body. 2. By setting up a drive gear, drive rack, drive slide, drive screw, drive slider, and drive groove, the adjusting ring seat is driven to rotate synchronously; 3. By setting up a connecting sleeve, connecting slider, connecting slide rod and connecting spring, the ball is in contact with the outer wall of the aluminum rod body under the action of the connecting spring. When there is a large depression or protrusion on the surface of the aluminum rod body, the ball moves in the radial direction of the detection ring, and then the ball drives the connecting slide rod to move. The connecting slide rod drives the connecting slider to move, so that the triggering component triggers the warning light. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a device for detecting surface defects on aluminum poles used for overhead power lines. (Refer to...) Figures 1 to 4 The system includes a base 1. A detection ring 2 and a warning light 3 are mounted on top of the base 1. Several ball bearings 4 are arranged circumferentially along the axis of the detection ring 2 within the detection ring 2. A connecting assembly 5 is installed between the ball bearings 4 and the detection ring 2, connecting the ball bearings 4 and the detection ring 2. A trigger assembly 6 is installed within the connecting assembly 5, triggering the warning light 3. A set of brackets 11 is mounted on the base 1, with an adjusting ring seat 21 passing through the brackets 11. The brackets 11 and the adjusting ring seat 21 are rotatably connected, and the opposite surface of the adjusting ring seat 21 is fixedly connected to the detection ring 2. A drive assembly 7 is mounted on the base 1, driving the adjusting ring seat 21 to rotate synchronously. When inspecting the surface defects of the aluminum rod body, the aluminum rod body is inserted into multiple detection rings 2. Then, the driving assembly 7 uses the adjusting ring seat 21 to rotate the detection rings 2, adjusting the distribution of the balls 4 on the outer ring wall of the aluminum rod body. This ensures that the balls 4 are staggered on the outer ring wall of the aluminum rod body, reducing the chance of missing surface defects. Afterwards, the connecting assembly 5 brings the balls 4 into contact with the aluminum rod body. At this time, the triggering assembly 6 does not activate the warning light 3. During the movement of the aluminum rod body, if there is a large depression or protrusion on the surface of the aluminum rod body, the balls 4 move radially along the detection ring 2, triggering the triggering assembly 6 to activate the warning light 3, alerting the operator. This reduces the chance of missed detection due to surface defects and missed balls 4, improving the quality of surface defect inspection of the aluminum rod body.

[0031] Reference Figure 1 and Figure 2The drive assembly 7 includes a set of drive gears 71, a set of drive racks 72, a drive slide block 73, a drive screw 74, and a drive slider 75. A drive groove 76 is formed on the base 1, and the drive slider 75 is slidably disposed within the drive groove 76, with the drive slider 75 fixedly connected to the drive slide block 73. The drive screw 74 is rotatably disposed within the drive groove 76, and the drive slider 75 is threadedly connected to the drive screw 74. The drive racks 72 are fixedly mounted on the drive slide block 73, with one drive rack 72 meshing with one drive gear 71 and the other drive rack 72 meshing with the other drive gear 71. One drive gear 71 is sleeved on one adjusting ring seat 21, and the other drive gear 71 is sleeved on another adjusting ring seat 21. Rotating the drive screw 74 causes the drive slider 75 to move along the drive groove 76, and the movement of the drive slider 75 causes the drive slide block 73 to move. The movement of the drive slide 73 causes the drive rack 72 to slide synchronously, the synchronous sliding of the drive rack 72 causes the drive gear 71 to rotate synchronously, and the synchronous rotation of the drive gear 71 causes the adjusting ring seat 21 to rotate synchronously.

[0032] Reference Figures 3 to 5 The connecting assembly 5 includes a connecting sleeve 51, a connecting slider 52, a connecting rod 53, and a connecting spring 54. An electric cylinder 8 is mounted between the connecting sleeve 51 and the detection ring 2. The electric cylinder 8 is fixedly mounted on the detection ring 2, and its output shaft is fixedly connected to one end of the connecting sleeve 51. The extension and retraction of the output shaft of the electric cylinder 8 adjusts the distance between the connecting sleeve 51 and the inner wall of the detection ring 2. The connecting slider 52 is slidably disposed inside the connecting sleeve 51. One end of the connecting spring 54 is connected to the inner wall of the connecting sleeve 51, and the other end of the connecting spring 54 is connected to the connecting slider 52. The end of the connecting slider 52 away from the connecting spring 54 is connected to one end of the connecting rod 53. The other end of the connecting rod 53 passes through the end of the connecting sleeve 51 away from the electric cylinder 8, and the connecting rod 53 is slidably connected to the connecting sleeve 51. The end of the connecting rod 53 located outside the connecting sleeve 51 is connected to a ball bearing 4. Several spheres 41 are rotatably disposed on the outer wall of the ball bearing 4. When the aluminum rod body is inserted into the detection ring 2, it is positioned between the balls 4. The balls 4, under the action of the connecting spring 54, adhere to the outer wall of the aluminum rod body. The ball 41 transforms the sliding friction between the balls 4 and the aluminum rod body into rolling friction, reducing the frictional force between them. By adjusting the distance between the connecting sleeve 51 and the inner wall of the detection ring 2, the warning light 3 is not triggered when the balls 4 contact a defect-free area on the surface of the aluminum rod body.

[0033] Reference Figure 3 and Figure 4 The trigger assembly 6 is installed between the inner wall of the connecting sleeve 51 and the outer wall of the connecting slider 52. When there is a large depression or protrusion on the surface of the aluminum rod body, the ball 4 moves radially along the detection ring 2, and then the ball 4 drives the connecting slider 53 to move. The connecting slider 53 drives the connecting slider 52 to move, causing the trigger assembly 6 to trigger the warning light 3.

[0034] Reference Figure 4 The trigger assembly 6 includes a set of contact blocks 61 and a set of sensors 62. Sensors 62 are installed inside the connecting sleeve 51, with the sensors 62 facing each other. The connecting slider 52 is located between the facing surfaces of the sensors 62. One side of the connecting slider 52 is connected to one of the contact blocks 61, and the other side is connected to another contact block 61. One contact block 61 is facing one of the sensors 62, and the other contact block 61 is facing the other sensor 62. When there is a large depression or protrusion on the surface of the aluminum rod body, the ball bearing 4 moves radially along the detection ring 2, which in turn drives the connecting slide bar 53 to move. The connecting slide bar 53 drives the connecting slider 52 to move, and the movement of the connecting slider 52 drives the contact blocks 61 to move. When the contact block 61 contacts the sensor 62, the warning light 3 is triggered.

[0035] The implementation principle of the surface defect detection device for overhead conductor aluminum poles in this application embodiment is as follows: When detecting surface defects on the aluminum pole body, the aluminum pole body is inserted into multiple detection rings 2. Then, the drive screw 74 is rotated to make the adjusting ring seat 21 drive the detection rings 2 to rotate, adjusting the distribution position of the balls 4 on the outer ring wall of the aluminum pole body, so that the balls 4 are staggered on the outer ring wall of the aluminum pole body, reducing the chance of missing surface defects on the aluminum pole body. Then, the distance between the connecting sleeve 51 and the inner wall of the detection ring 2 is adjusted by the electric cylinder 8, so that the warning light 3 is not triggered when the balls 4 contact the defect-free parts of the aluminum pole body surface. During the movement of the aluminum pole body, if there is a large depression or protrusion on the surface of the aluminum pole body, the balls 4 move radially along the detection ring 2, and then the balls 4 drive the connecting slide rod 53 to move, the connecting slide rod 53 drives the connecting slider 52 to move, and the moving connecting slider 52 drives the contact block 61 to move. When the contact block 61 contacts the sensor 62, the warning light 3 is triggered to alarm and remind the staff. This reduces the chance of missed detection due to surface defects on the aluminum rod body and missing balls, thus improving the quality of surface defect detection on the aluminum rod body.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
