Description

Technical Field

[0001] This utility model relates to the field of inspection robots, and in particular to a rail-mounted inspection robot. Background Technology

[0002] A track-mounted robot is a type of robot primarily used in computer rooms, substations, utility tunnels, and other similar environments. Equipped with cameras and sensors, it performs scheduled or real-time inspections. Before use, a track needs to be installed on the roof of the building. The robot will then move forward or backward along the track. Cameras mounted on the lower part of the robot capture the status of various devices within its work area, transmitting the photos and video files to a remote monitoring system.

[0003] Existing track-mounted inspection robots move along the track and are guided by the contact between rollers and track grooves. This results in insufficient stability when the robot is running on the track. When the track on which the inspection robot is running has slight bending or deformation, the pressure between the rollers and the track changes, thereby increasing the risk of the robot deviating from the track. To address these issues, a track-mounted inspection robot is proposed. Utility Model Content

[0029] 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.

[0030] Reference Figure 1 , Figure 2 The present invention provides an embodiment of a rail-mounted inspection robot, comprising a shell 1 and a track 2. The shell 1 is the outer shell of the inspection robot. The surface of the track 2 is provided with a groove 3. The cross-sectional shape of the track 2 is set as "I". The interior of the shell 1 is provided with a moving component 4, which includes multiple rollers 5. The surface of the rollers 5 contacts the inner wall of the groove 3. The rollers 5 are used to guide the shell 1 to move along the track 2. The rollers 5 are driven by the built-in drive motor of the inspection robot, which drives the inspection robot to move forward or backward along the track 2.

[0031] Reference Figure 2 - Figure 4The outer casing 1 includes a control component 7 and a monitoring component 22. The outer casing 1 is fitted over the outside of the track 2. The control component 7 includes a screw 8 and a slant rod 15. The screw 8 is threadedly connected to the inner wall of the outer casing 1. By rotating the knob 9, the knob 9 drives the screw 8 to rotate. Since the screw 8 is threadedly connected to the inner wall of the outer casing 1, the rotation of the screw 8 will cause the moving block 10 to move linearly along the slide groove 13. The number of screws 8 is set to two sets. The knob 9 is fixedly connected to the side of the two sets of screws 8 that is far away from each other. The surface of the knob 9 is provided with anti-slip texture to improve friction and reduce the possibility of the operator slipping when rotating the knob 9. The moving block 10 is rotatably connected to the surface of the screw 8. The inner side of the outer casing 1 is provided with a slide groove 13. The moving block 10 is slidably connected to the inner wall of the slide groove 13. The sliding direction of the moving block 10 is back and forth.

[0032] Reference Figure 3 , Figure 4 A slider 12 is slidably connected to the inner wall of the groove 13. The slider 12 is elastically connected to the moving block 10 through a spring 11. By setting the spring 11, the slider 12 and the moving block 10 tend to move away from each other. A connecting rod 14 is hinged to the surface of the slider 12. The connecting rod 14 is hinged to the middle of the inclined rod 15. One end of the inclined rod 15 is hinged to the inner wall of the outer shell 1, and the other end of the inclined rod 15 is hinged to a guide wheel 16. The guide wheel 16 contacts the inner wall of the groove 3. When the track 2 has a slight bend or the robot deviates, the elastic adjustment mechanism of the guide wheel 16 and the inclined rod 15, together with the guide wheel 16 contacting the inner wall of the groove 3, ensures that the robot runs in the center and improves the stability of the robot when running on the track 2.

[0033] Reference Figure 1 The monitoring component 22 includes a stepper motor 17, which is fixedly connected to the bottom of the housing 1. The stepper motor 17 can precisely control the rotation angle of its output shaft, and it is convenient to adjust the rotation speed and rotation angle of its output shaft. It can be adjusted according to different working requirements, thereby improving the control accuracy. A vertical rod 18 is fixedly connected to the bottom of the output shaft of the stepper motor 17. The monitoring component 22 also includes a connecting block 19, the top of which is fixedly connected to the bottom of the vertical rod 18.

[0034] Reference Figure 1 The monitoring component 22 also includes a camera 20, which can capture images and videos of the scene and record the appearance of the equipment, whether there are foreign objects, etc. The camera 20 is fixedly connected to the rear side of the connecting block 19. The monitoring component 22 also includes an infrared thermal imager 21, which can scan abnormal temperature points of the equipment and provide early warning information. The infrared thermal imager 21 is fixedly connected to the front side of the connecting block 19.

[0035] Working principle: During use, rotating the knob 9 drives the screw 8 to rotate. Since the screw 8 is threadedly connected to the inner wall of the outer casing 1, the rotating screw 8 will drive the moving block 10 to move along the axis of the screw 8 in the slide groove 13. The moving block 10 is elastically connected to the slider 12 through the spring 11. Therefore, when the moving block 10 moves, the slider 12 will also slide in the slide groove 13. However, due to the presence of the spring 11, the position of the slider 12 can have a certain fine adjustment space relative to the moving block 10.

[0036] The sliding of slider 12 drives the movement of connecting rod 14. Connecting rod 14 is hinged to the middle of inclined rod 15. Therefore, the movement of connecting rod 14 will cause inclined rod 15 to rotate around its hinge point with the inner wall of outer shell 1. The other end of inclined rod 15 is hinged to guide wheel 16. As inclined rod 15 rotates, guide wheel 16 will be pushed or pulled away from the inner wall of groove 3 of track 2, thereby adjusting the tightness of inspection robot on track 2 and ensuring that inspection robot can move stably and closely on track 2.

[0037] By rotating the screw 8, the guide wheel 16 is controlled to apply pressure to the groove 3 of the track 2, which improves the stability of the robot in the complex section of the track 2, reduces the risk of derailment, and enables the robot to operate stably in the track 2, thereby reducing maintenance and repair costs.

[0038] When the inspection robot is ready to start working, the built-in motor drives the roller 5 to rotate, so that the inspection robot moves along the track 2. The camera 20 can capture images and videos of the scene, record the appearance of the equipment, whether there are foreign objects, etc. The infrared thermal imager 21 can detect the temperature distribution on the surface of the equipment and promptly detect potential faults, such as overheating. The stepper motor 17 works, so that the camera 20 and the infrared thermal imager 21 on the surface of the bottom connecting block 19 of the vertical rod 18 can rotate 360 ​​degrees, thereby improving the monitoring range of the robot inspection.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
