Abstract
Description
Technical Field
[0001] This utility model relates to the field of robot positioning equipment technology, and in particular to a positioning device for inspection robots. Background Technology
[0002] During the operation of inspection robots, accurate location of equipment faults is crucial to ensuring efficient maintenance. Traditional inspection robot positioning methods rely on technologies such as GPS and LiDAR to record fault coordinates. However, in actual maintenance, workers often need to spend a lot of time searching for specific fault points based on coordinates, especially in complex environments. Errors in coordinate positioning can make fault points difficult to find. Although positioning can be achieved, it lacks the function of directly marking the fault location, or the marking is not clear or durable enough. In scenarios with dense equipment and complex environments, it cannot provide maintenance personnel with intuitive fault guidance. Therefore, this application proposes an inspection robot positioning device. Utility Model Content
[0003] The purpose of this invention is to address the problem in the prior art that it is impossible to directly mark the location of a fault by physical means, and to propose a positioning device for inspection robots.

[0009] Optionally, the positioning label structure includes bottom connecting plates fixed to both sides of the bottom end of the base plate, with transmission pipes fixedly connected to the bottom ends of the two bottom connecting plates, and the top ends of the two transmission pipes sequentially passing through the bottom connecting plates, the base plate, and the placement plate.
[0010] Optionally, telescopic frames are fixedly connected to both sides of the outer wall of the two transmission tubes, and sliding rods are slidably connected to the bottom ends of the two telescopic frames.
[0011] Optionally, the ends of the plurality of sliding rods away from the telescopic frame are fixedly connected to the bottom end of the bottom connecting plate, and the plurality of sliding rods are located on both sides of the outer wall of the transmission pipe.
[0012] Optionally, the bottom end of the transmission pipe is threadedly connected to a discharge pipe, and the inner wall of the discharge pipe is connected to a discharge port.

[0025] Example 1
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the inspection robot positioning device proposed in this utility model includes a connecting seat 1. A rotating joint 2 is rotatably connected to the inner wall of the connecting seat 1. Connecting frames 3 are fixedly connected to both sides of the outer wall of the rotating joint 2. A base plate 4 is fixedly connected to the end of the two connecting frames 3 away from the rotating joint 2. An extrusion structure is provided at the top of the base plate 4. The extrusion structure includes support columns 5 fixed to both sides of the top of the base plate 4. A top plate 7 is fixedly connected to the top of the two support columns 5 through a top rod 6. A hydraulic pump 8 is provided at the top of the top plate 7. A hydraulic rod 9 is slidably connected to the output end of the hydraulic pump 8, and a pressure block 11 is fixedly connected to the bottom end of the hydraulic rod 9 through a push terminal 10. The connecting seat 1 is made of high-strength metal material. A rotating joint 2 is rotatably connected to the inner wall. The rotating joint 2 adopts a bearing structure to achieve rotation, which facilitates the adjustment of the device's direction. Connecting brackets 3 are fixedly connected to both sides of the outer wall of the rotating joint 2. They are made of the same material as the connecting seat 1 and serve as connections and supports. A base plate 4 is fixedly connected to the end away from the rotating joint 2. The base plate 4 is made of metal sheet and provides an installation platform for other subsequent structures, ensuring the stability of the entire device. In addition, the support columns 5 fixed to both sides of the top of the base plate 4 are made of metal and have high strength and stability. The top plate 7 is fixedly connected to the top via a push rod 6, providing an installation position for the hydraulic pump 8. The hydraulic pump 8 provides power for extrusion, and its output end is slidably connected to a hydraulic rod 9. The bottom end of the hydraulic rod 9 is fixedly connected to a pressure block 11 via a push terminal 10. The shape of the pressure block 11 can be changed to match the shape of the labeled material on the placement plate 15. When the hydraulic pump 8 works, it drives the hydraulic rod 9 to extend and retract downwards, which drives the pressure block 11 to move downwards through the push terminal 10, squeezing the labeled material on the placement plate 15 and causing it to enter the transmission pipe 17.
[0027] As one implementation method, such as Figure 3 As shown, a fixing structure is provided on both sides of the top of the base plate 4. The fixing structure includes a support frame 12 fixedly connected to the other two sides of the top of the base plate 4. A telescopic rod 13 is fixedly connected to the inner bottom end of the support frame 12. A spring fixing frame 14 is fixedly connected to the bottom end of the two telescopic rods 13. A placement plate 15 is fixedly connected to the top of the base plate 4. The placement plate 15 corresponds to the two spring fixing frames 14. The support frame 12 fixedly connected to the other two sides of the top of the base plate 4 is made of metal. The telescopic rod 13 is fixedly connected to the inner bottom end. The telescopic rod 13 is an electric telescopic rod. The spring fixing frame 14 is fixedly connected to the bottom end to fix the labeling material on the placement plate 15 and prevent it from shifting during the extrusion process. The placement plate 15 corresponds to the two spring fixing frames 14 and is used to place labeling materials such as pigments and marking pastes. Its position corresponds to the top of the pressure block 11 and the transfer tube 17 to ensure that the labeling material can be smoothly extruded into the transfer tube 17.
[0028] Furthermore, such as Figure 2 and Figure 4 As shown, a positioning mark structure is provided at the bottom end of the base plate 4. The positioning mark structure includes bottom end connecting plates 16 fixed to both sides of the bottom end of the base plate 4. The bottom ends of the two bottom end connecting plates 16 are fixedly connected to the bottom ends of the two bottom end connecting plates 16, and the top ends of the two bottom end connecting plates 16, the base plate 4 and the placement plate 15 pass through the bottom end connecting plates 16, the base plate 4 and the placement plate 15 in sequence. The outer walls of the two bottom end connecting plates 17 are fixedly connected to the telescopic frames 18, and the bottom ends of the two telescopic frames 18 are slidably connected to the sliding rods 19. The ends of the multiple sliding rods 19 away from the telescopic frames 18 are fixedly connected to the bottom ends of the bottom end connecting plates 16, and the multiple sliding rods 19 are located on both sides of the outer walls of the bottom end connecting plates 17. The bottom end connecting plates 16 fixed to both sides of the bottom end of the base plate 4 are made of metal and are used to connect and fix the bottom end connecting plates 16. The transfer pipe 17 is made of corrosion-resistant metal, with its top end sequentially passing through the bottom connecting plate 16, the bottom plate 4, and the placement plate 15. It communicates with the marking material on the placement plate 15 and is used to transfer the extruded marking material downwards. Telescopic frames 18, made of metal or high-strength plastic, are fixedly connected to both sides of the outer wall of the transfer pipe 17 and are adjustable in length and width. A sliding rod 19 is slidably connected to the bottom end. The sliding rod 19 is made of metal, with its end away from the telescopic frame 18 fixedly connected to the bottom end of the bottom connecting plate 16. It guides and supports the telescopic frame 18, ensuring the stability of the transfer pipe 17 during the marking process. The discharge pipe 20, threaded to the bottom end of the transfer pipe 17, is made of metal or plastic for easy disassembly and replacement. Different diameter discharge pipes 20 can be selected as needed. The inner wall of the discharge pipe 20 is connected to a discharge port 21, made of wear-resistant material. The outlet shape can be designed according to the marking requirements, such as round or square, to ensure clear and accurate marking.
[0029] In this embodiment, it should be noted that during the inspection process, after identifying the location of the equipment fault, the inspection robot adjusts the direction of the base plate 4 by rotating the joint 2 on the connecting seat 1, so that the discharge port 21 of the positioning mark structure is aligned with the equipment fault point, ensuring accurate marking direction. Suitable marking materials, such as high-temperature resistant pigments or waterproof marking paste, are selected and placed on the placement plate 15. By adjusting the telescopic rod 13, the spring fixing frame 14 tightly presses down on the marking material to prevent displacement during the robot's movement towards the fault point, ensuring a stable supply of marking material. The hydraulic pump 8 is started, driving the hydraulic rod 9 to extend and retract downwards. The pressure block 11 squeezes the marking material on the placement plate 15, and the material enters the transmission pipe 17 under pressure. Based on the height and distance of the equipment fault point, the telescopic frame 18 is adjusted to slide on the slide rod 19, so that the discharge port 21 is close to the surface of the fault point. The marking material is extruded from the discharge port 21 through the transmission pipe 17 and the discharge pipe 20, forming a mark of a preset shape at the equipment fault location.
[0030] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
