[0002] The rail-mounted inspection robot is an automated device that can perform specific inspection and monitoring tasks in harsh and special environments. The rail-mounted inspection robot detects the environment in real time through sensors and transmits the data to the control center. The control center analyzes and processes the data to achieve real-time monitoring of environmental conditions. At the same time, the robot can also conduct autonomous inspections according to preset routes and promptly alarm when hidden dangers are found, effectively improving inspection efficiency and safety.

[0003] At present, there are still some problems in the current use of rail-mounted inspection robots. The rail-mounted inspection robots use gear transmission to move, and there is mechanical contact and friction during use. After long-term use, oil will be generated on the guide rails, which will cause positioning errors during movement. It has become a major difficulty to achieve stable linear drive control and accurate position information acquisition. Therefore, the applicant has designed a contactless drive and precise positioning system for the rail-mounted inspection robot, which provides a reasonable and low-cost solution to ensure the stable linear movement and accurate position information acquisition of the inspection robot.

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments; in the following description, specific details such as specific configurations and components are provided only to help fully understand the embodiments of the present invention. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. In addition, for the sake of clarity and brevity, the description of known functions and structures is omitted.

[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.

[0030] like Figure 1-5 The present embodiment shows a contactless driving and precise positioning system of a rail-mounted inspection robot, comprising: a slide 100, a track 200 and a servo motor 300; a receiving space 110 is provided on the slide 100; a plurality of stands 120 are fixedly mounted on the receiving space 110; a pulley 121 is mounted on the stand 120; the pulley 121 is slidably mounted on the track 200; the servo motor 300 is fixed in the receiving space 110; a magnetic gear 310 is mounted on the output end of the servo motor 300; an iron columnar tooth 210 is provided on one side of the track 200; the magnetic gear 310 and the iron columnar tooth 210 are in non-contact meshing engagement.

[0031] Specifically, when the inspection robot needs to move in a straight line, the servo motor 300 is started, so that the magnetic gear 310 starts to rotate. There is a magnetic attraction between the magnetic gear 310 and the iron columnar teeth 210. Therefore, when the magnetic gear 310 rotates, the magnetic attraction between it and the iron columnar teeth 210 will drive the magnetic gear 310 to generate forward power, and then the magnetic gear 310 drives the movement of the servo motor 300, and the servo motor 300 drives the movement of the entire slide 100. Therefore, the magnetic gear 310 and the iron columnar teeth 210 on the track 200 can achieve non-contact meshing, thereby realizing the movement of the magnetic gear 310, which can effectively reduce the power consumption of the equipment, greatly reduce the heat generated, reduce the mechanical contact and friction between the equipment, and no oil stains will be generated on the guide rail.

[0032] Furthermore, the magnetic gear 310 is coaxially connected to the first gear 320, a second gear 122 is installed on one of the stands 120, the first gear 320 is meshed with the second gear 122, an encoder 400 is also fixed in the accommodating space 110, a third gear 410 is installed on the encoder 400, the second gear 122 is meshed with the third gear 410.

[0033] Specifically, when the servo motor 300 is started and the first gear 320 starts to rotate, the first gear 320 drives the second gear 122 to rotate, and finally the second gear 122 drives the third gear 410 at one end of the encoder 400 to start rotating. The servo motor 300 and the encoder 400 work together, and the two transmit kinetic energy through the second gear 122. The encoder 400 converts the rotational displacement of the servo motor 300 into a series of digital pulse signals, which can be used to measure the number of rotations of the servo motor 300, and then can be used to accurately measure the linear displacement of the inspection robot.

[0034] Furthermore, a plurality of electronic tags 220 are attached to the side of the track 200 at intervals, and an RFID reader 500 is installed in the accommodation space 110 on the side of the track 200 where the electronic tags 220 are attached.

[0035] Furthermore, the distance between every two adjacent electronic tags 220 is 20 centimeters.

[0036] Specifically, the RFID reader 500 is an automatic identification device that can read the data of the electronic tag 220. The RFID reader 500 and the electronic tag 220 work together. The RFID reader 500 moves with the inspection robot. The electronic tag 220 is attached to the side of the track 200, one every 20 centimeters. The RFID reader 500 moves to the bottom of the electronic tag 220 to read the position information it carries, thereby obtaining the precise positioning of the inspection robot; the positioning of this system is completed by the servo motor 300, the encoder 400, the RFID reader 500, and the electronic tag 220, and the positioning accuracy is greatly improved.
