Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, specifically a positioning device for a rail-mounted inspection robot. Background Technology

[0002] A rail-mounted inspection robot is an intelligent device installed on a specific track. It is mainly used to autonomously inspect and monitor various facilities and environments on a fixed track. The positioning of a rail-mounted inspection robot refers to determining the robot's specific position on the track through specific technical means.

[0003] Currently, when positioning a rail-mounted inspection robot, it can do so by scanning the barcode strip on the rail with a barcode scanner on the robot. However, this method has some shortcomings. Because the environment in which the rail-mounted inspection robot autonomously inspects and monitors is not dust-free, dust may be present. Over time, dust may accumulate on the rail, potentially obscuring the barcode strip attached to it. This would prevent the barcode scanner from successfully scanning the barcode strip, thus affecting the positioning success rate.

[0004] While directly adding cleaning cotton to clean the dust on the slide rail can remove the dust, the long-term contact between the cleaning cotton and the slide rail increases friction and causes the cleaning cotton to wear out more quickly. This necessitates frequent replacement of the cleaning cotton to prevent dust adhering to its surface from affecting subsequent cleaning. To address these issues, the inventor proposes a positioning device for a track-mounted inspection robot. Utility Model Content

[0005] To address the issue of poor positioning success rate in current rail-mounted inspection robots, the purpose of this invention is to provide a positioning device for rail-mounted inspection robots.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a positioning device for a rail-mounted inspection robot, comprising a rail-mounted inspection robot body and a slide rail, wherein a barcode strip is bonded to the side wall of the slide rail, a barcode scanner is provided on the inner wall of the rail-mounted inspection robot body, the working end of the barcode scanner corresponds to the barcode strip, a shell is fixedly connected to the outer side wall of the rail-mounted inspection robot body, a boss is fixedly connected to the inner bottom wall of the shell, a first rotating disk is damped and rotatably connected to one side of the top surface of the boss, a column is fixedly connected to the middle of the top surface of the first rotating disk, a cleaning cloth roll is sleeved on the side wall of the column, a second rotating disk is rotatably connected to the other side of the top surface of the boss, a fixed clamping plate is fixedly connected to the middle of the top surface of the second rotating disk, a movable clamping plate is adjustablely provided on the side wall of the fixed clamping plate, an electric cylinder is provided between the first rotating disk and the second rotating disk, a concave plate is fixedly connected to the output shaft end of the electric cylinder, and a vertical cylinder is fixedly connected to the concave opening of the concave plate.

[0007] Preferably, a slot is provided through the side of the housing, and an opening and closing cover is detachably provided on the top surface of the housing. A limit cover is provided above the column, and a threaded rod is fixedly connected to the center of the bottom surface of the limit cover. A threaded hole is provided through the center of the top surface of the column, and the threaded rod corresponds to and cooperates with the threaded hole. The diameter of the limit cover is larger than the diameter of the column. The main body of the rail-mounted inspection robot, the barcode scanner, and the barcode tape are existing mature products, and no modifications are made here; they are simply selected directly. The barcode tape is a graphic identifier composed of alternating black and white stripes. Its working principle is to represent different information by varying the width of the black and white stripes. When the light emitted by the barcode scanner shines on the barcode tape... When the barcode scanner is in operation, the black stripes absorb light, while the white stripes reflect light. The photoelectric converter inside the barcode scanner captures these changes in reflected light and converts them into electrical signals. These electrical signals are then decoded to restore the data information represented by the barcode, which is used to locate the main body of the rail-mounted inspection robot. This is a mature existing technology and will not be elaborated on further here. The opening and closing cover can be opened and closed. When the cleaning cloth roll needs to be installed on the first rotating plate, open the opening and closing cover, twist the limiting cover, and remove the limiting cover from the column through the cooperation of the threaded rod and the threaded hole. Then, put the end of the cleaning cloth roll onto the column, and then install the limiting cover on the column to limit the cleaning cloth roll placed on the column.

[0008] Preferably, a motor is installed inside the boss, and the output shaft of the motor is fixedly connected to the center of the bottom surface of the second rotating disk. A base is provided on the side wall of the motor, and the base is fixedly connected to the inner wall of the boss. The motor is mounted through the base. When the motor is started, the second rotating disk rotates under the action of the motor output shaft, thereby causing the fixed clamping plate and the movable clamping plate to rotate. The movable clamping plate corresponds to the fixed clamping plate. Studs are fixedly connected to the upper and lower ends of the side of the fixed clamping plate, and the studs penetrate the movable clamping plate. A nut is installed on the side of the clamping plate facing away from the fixed clamping plate. The nut cooperates with the stud. After the cleaning cloth roll is installed, the cloth end of the cleaning cloth roll is placed between the movable clamping plate and the fixed clamping plate. Then, the nut is turned. Through the cooperation of the nut and the stud, the movable clamping plate can be moved towards the fixed clamping plate to clamp and fix the cloth end of the cleaning cloth roll. When the second rotating disk rotates, the fixed clamping plate and the movable clamping plate can be rotated, so that the cleaning cloth on the cleaning cloth roll can be wound on the fixed clamping plate and the movable clamping plate.

[0009] Preferably, a support frame is fixedly connected to the top surface of the boss, the outer shell of the electric cylinder is fixedly connected to the side wall of the support frame, and a guide rod is slidably connected to the side wall of the support frame. One end of the guide rod is fixedly connected to the side wall of the concave plate. When it is necessary to position the main body of the rail-mounted inspection robot, the electric cylinder can be started first. Under the action of the output shaft of the electric cylinder, the concave plate can drive the vertical cylinder to move, so that the cleaning cloth unfolded on the cleaning cloth roll contacts the side wall of the slide rail. While the main body of the rail-mounted inspection robot moves on the slide rail, the side wall of the slide rail can be wiped and cleaned by the cleaning cloth, thereby completing the positioning. The barcode tape is cleaned nearby to prevent dust from affecting the barcode scanner's scanning and thus the positioning response rate. After positioning is completed, the electric cylinder can be controlled to move the vertical cylinder away from the slide rail to avoid the cleaning cloth being in long-term contact with the side wall of the slide rail. When the next positioning operation is required, the motor is started, and the second rotating disk rotates under the action of the motor output shaft. This allows the used cleaning cloth to be wound on the fixed clamp and the movable clamp, thus unrolling the cleaning cloth and spreading it out for wiping, avoiding the dust on the cleaning cloth from affecting the cleaning effect.

[0010] Compared with existing technologies, the advantages of this utility model are as follows: it can improve the positioning success rate. When positioning the main body of the rail-mounted inspection robot moving on the slide rail using a barcode scanner and barcode tape, the unfolded cloth on the cleaning cloth roll can be moved to wipe and clean the barcode tape on the slide rail, thereby avoiding dust on the barcode tape from affecting the barcode scanner's scanning and thus affecting the positioning response rate. After positioning is completed, the unfolded cleaning cloth can be separated from the slide rail by an electric cylinder to avoid the cleaning cloth from being in contact with the slide rail for a long time and increasing friction. When the next positioning operation is required, the used cleaning cloth can be wound up to unfold the unused cleaning cloth on the cleaning cloth roll for wiping, thereby avoiding dust on the used cleaning cloth from affecting the cleaning effect and improving the positioning success rate.

[0017] 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.

[0018] Example: Figure 1-4 As shown, this utility model provides a positioning device for a rail-mounted inspection robot, including a rail-mounted inspection robot body 1 and a slide rail 24. A barcode strip 25 is bonded to the side wall of the slide rail 24. A barcode scanner 2 is installed on the inner wall of the rail-mounted inspection robot body 1, with the working end of the barcode scanner 2 corresponding to the barcode strip 25. A housing 3 is fixedly connected to the outer wall of the rail-mounted inspection robot body 1. A boss 6 is fixedly connected to the inner bottom wall of the housing 3. A first rotating disk 7 is damped and rotatably connected to one side of the top surface of the boss 6. A column 9 is fixedly connected to the center of the top surface of the rotating disk 7. A cleaning cloth roll 8 is sleeved on the side wall of the column 9. A second rotating disk 14 is rotatably connected to the other side of the top surface of the boss 6. A fixed clamping plate 15 is fixedly connected to the center of the top surface of the second rotating disk 14. A movable clamping plate 17 is adjustablely provided on the side wall of the fixed clamping plate 15. An electric cylinder 20 is provided between the first rotating disk 7 and the second rotating disk 14. A concave plate 21 is fixedly connected to the output shaft end of the electric cylinder 20. A vertical cylinder 22 is fixedly connected to the concave opening of the concave plate 21.

[0019] A slot 5 is provided through the side of the housing 3. An opening and closing cover 4 is detachably provided on the top surface of the housing 3. A limit cover 11 is provided above the column 9. A threaded rod is fixedly connected to the middle of the bottom surface of the limit cover 11. A threaded hole 10 is provided through the middle of the top surface of the column 9. The threaded rod corresponds to and cooperates with the threaded hole 10. The diameter of the limit cover 11 is larger than the diameter of the column 9.

[0020] By adopting the above technical solution, the main body 1 of the rail-mounted inspection robot, the barcode scanner 2, and the barcode strip 25 are existing mature products, and no modifications are made; they are simply selected directly. The barcode strip 25 is a graphic identifier composed of alternating black and white stripes. Its working principle is to represent different information by varying the width of the black and white stripes. When light emitted by the barcode scanner 2 shines on the barcode strip 25, the black stripes absorb the light, while the white stripes reflect the light. The photoelectric converter inside the barcode scanner 2 captures these changes in reflected light and converts them into electrical signals. These electrical signals are then... The data information represented by the barcode is restored by the decoder to locate the main body 1 of the rail-mounted inspection robot. This is an existing mature technology and will not be described in detail here. The opening and closing cover 4 can be opened and closed. When the cleaning cloth roll 8 needs to be installed on the first rotating disk 7, the opening and closing cover 4 is opened and the limiting cover 11 is turned. Through the cooperation of the threaded rod and the threaded hole 10, the limiting cover 11 is removed from the column 9. Then, the roll opening of the cleaning cloth roll 8 is put on the column 9, and then the limiting cover 11 is installed on the column 9, which can limit the cleaning cloth roll 8 placed on the column 9.

[0021] A motor 12 is installed inside the boss 6. The output shaft end of the motor 12 is fixedly connected to the center of the bottom surface of the second rotating disk 14. A base 13 is provided on the side wall of the motor 12, and the base 13 is fixedly connected to the inner wall of the boss 6.

[0022] By adopting the above technical solution, the motor 12 is installed on the base 13. When the motor 12 is started, the second rotating disk 14 rotates under the action of the output shaft of the motor 12, which in turn causes the fixed clamping plate 15 and the movable clamping plate 17 to rotate.

[0023] The movable clamping plate 17 corresponds to the fixed clamping plate 15. The upper and lower ends of the side of the fixed clamping plate 15 are fixedly connected with studs 16, and the studs 16 pass through the movable clamping plate 17. A nut 18 is provided on the side of the movable clamping plate 17 facing away from the fixed clamping plate 15, and the nut 18 cooperates with the stud 16.

[0024] By adopting the above technical solution, after the installation of the cleaning cloth roll 8 is completed, the cloth end of the cleaning cloth roll 8 is placed between the movable clamping plate 17 and the fixed clamping plate 15. Then, the nut 18 is turned. Through the cooperation between the nut 18 and the stud 16, the movable clamping plate 17 can be moved towards the fixed clamping plate 15 to clamp and fix the cloth end of the cleaning cloth roll 8. When the second rotating disk 14 rotates, the fixed clamping plate 15 and the movable clamping plate 17 can be rotated, so that the cleaning cloth on the cleaning cloth roll 8 can be wrapped around the fixed clamping plate 15 and the movable clamping plate 17.

[0025] A support frame 19 is fixedly connected to the top surface of the boss 6. The outer shell of the electric cylinder 20 is fixedly connected to the side wall of the support frame 19. A guide rod 23 is slidably connected to the side wall of the support frame 19. One end of the guide rod 23 is fixedly connected to the side wall of the concave plate 21.

[0026] By adopting the above technical solution, when positioning the main body 1 of the rail-mounted inspection robot is required, the electric cylinder 20 can be activated first. Under the action of the output shaft of the electric cylinder 20, the concave plate 21 can drive the vertical cylinder 22 to move, so that the cleaning cloth unfolded on the cleaning cloth roll 8 contacts the side wall of the slide rail 24. While the main body 1 of the rail-mounted inspection robot moves on the slide rail 24, the side wall of the slide rail 24 can be wiped clean with the cleaning cloth, thereby completing the cleaning of the barcode tape 25 in the vicinity, preventing dust on the barcode tape 25 from affecting the scanning of the barcode scanner 2. The response rate of positioning is affected. After positioning is completed, the electric cylinder 20 can be controlled to move the vertical cylinder 22 away from the slide rail 24 to avoid the cleaning cloth from being in long-term contact with the side wall of the slide rail 24. When positioning is required again, the motor 12 is started and the second rotating disk 14 rotates under the action of the output shaft of the motor 12. This allows the used cleaning cloth to be wound on the fixed clamping plate 15 and the movable clamping plate 17, thereby unfolding the unused cleaning cloth on the cleaning cloth roll 8 for wiping, avoiding the dust on the cleaning cloth from affecting the cleaning effect.

[0027] Working principle: When using this utility model, the opening and closing cover 4 is opened, the limiting cover 11 is turned, and the limiting cover 11 is removed from the column 9 through the mutual cooperation of the threaded rod and the threaded hole 10. Then, the roll opening of the cleaning cloth roll 8 is put onto the column 9, and then the limiting cover 11 is installed on the column 9 to limit the cleaning cloth roll 8 placed on the column 9. After that, the cloth end of the cleaning cloth roll 8 is pulled to place the cloth end of the cleaning cloth roll 8 between the movable clamping plate 17 and the fixed clamping plate 15. Then, the nut 18 is turned, and through the mutual cooperation of the nut 18 and the stud 16, the movable clamping plate 17 can be moved towards the fixed clamping plate 15 to clamp and fix the cloth end of the cleaning cloth roll 8, and then the opening and closing cover 4 is closed.

[0028] When the main body 1 of the rail-mounted inspection robot moves on the slide rail 24, when it is necessary to position the main body 1 of the rail-mounted inspection robot, the electric cylinder 20 can be started first. The concave plate 21 can drive the vertical cylinder 22 to move under the action of the output shaft of the electric cylinder 20, so that the cleaning cloth unfolded on the cleaning cloth roll 8 comes into contact with the side wall of the slide rail 24. Thus, while the main body 1 of the rail-mounted inspection robot moves on the slide rail 24, the side wall of the slide rail 24 can be wiped and cleaned by the cleaning cloth, thereby completing the cleaning of the barcode tape 25 in the vicinity, so as to avoid the barcode tape 25 being covered with dust and affecting the scanning of the barcode scanner 2, thus affecting the positioning response rate.

[0029] After positioning is completed, the electric cylinder 20 can be controlled to move the vertical cylinder 22 away from the slide rail 24 to avoid the cleaning cloth from being in long-term contact with the side wall of the slide rail 24. When the positioning operation is required again, the motor 12 is started and the second rotating disk 14 rotates under the action of the output shaft of the motor 12. This allows the used cleaning cloth to be wrapped around the fixed clamping plate 15 and the movable clamping plate 17, thereby unfolding the unused cleaning cloth on the cleaning cloth roll 8 for wiping operation. This avoids the dust on the used cleaning cloth from affecting the cleaning effect and improves the success rate of positioning.

The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
