Locomotive body inspection robots significantly improve inspection efficiency and accuracy, reducing the workload and risks of manual inspection, making them an important tool for achieving intelligent and automated operations in the railway transportation industry.

[0004] In existing technologies, some inspection equipment can only perform inspections at fixed angles and cannot flexibly adjust the inspection position according to the actual situation of the locomotive's underside. For example, some equipment can only inspect a few specific parts of the locomotive's underside, and cannot cover other parts, thus failing to achieve efficient and comprehensive inspection. Such incomplete inspections may miss damage or malfunctions in some critical parts, posing a potential threat to the safe operation of the locomotive. Therefore, a locomotive body inspection robot is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a locomotive body inspection robot, which aims to improve the problem that some existing inspection equipment can only perform inspections at a fixed angle and easily miss damage to critical parts of the locomotive.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A locomotive body inspection robot includes a body, with two connecting frames fixedly connected to the left and right sides of the body respectively. An adjustment and retraction mechanism is rotatably connected inside the connecting frames, and a cleaning mechanism is fixedly connected to the top of the body.

[0008] The adjusting and retracting mechanism includes multiple rotating seats. The connecting frame has a square groove inside. The rotating seat is rotatably connected to the inside of the square groove. A cylinder is fixedly connected to the top of the rotating seat. A rotating block is fixedly connected to the driving end of the cylinder. A support plate is rotatably connected to the top of the connecting frame. A support plate is fixedly connected to the top of the support plate. A T-shaped sliding groove is opened at the bottom of the support plate. A T-shaped slider is slidably connected to the inner wall of the T-shaped sliding groove.

[0009] As a further description of the above technical solution:

[0010] The cleaning mechanism includes two light source plates, the bottom ends of which are fixedly connected to the left and right sides of the top of the machine body. The top of the machine body has a receiving groove, the bottom end of which is fixedly connected to an electric push rod. The driving end of the electric push rod is fixedly connected to an electric motor, and the driving end of the electric motor is fixedly connected to a rotating plate. Square blocks are fixedly connected to the left and right sides of the bottom of the rotating plate.

[0011] As a further description of the above technical solution:

[0012] The bottom four corners of the body are rotatably connected to wheels, and the top of the support plate is fixedly connected to two cameras;

[0013] As a further description of the above technical solution:

[0014] The rotating block is externally rotatably connected to the bottom of the T-shaped slider;

[0015] As a further description of the above technical solution:

[0016] A guide rod is fixedly connected to the inner wall of the T-shaped groove, and the inner wall of the T-shaped slider is slidably connected to the outer wall of the guide rod.

[0017] As a further description of the above technical solution:

[0018] A spring is sleeved on the outside of the guide rod. The opposite sides of the multiple springs are fixedly connected to the opposite inner walls of the multiple T-shaped slides. The near sides of the multiple springs are fixedly connected to the opposite sides of the multiple T-shaped sliders.

[0019] As a further description of the above technical solution:

[0020] A cleaning brush is fixedly connected to the bottom end of the square block, and the bottom side of the cleaning brush is in contact with the top side of the light source plate.

[0021] As a further description of the above technical solution:

[0022] The outer wall of the rotating plate is slidably connected to the inner wall of the receiving groove, and the bottom side of the cleaning brush is in contact with the bottom inner wall of the receiving groove.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the wheels at the bottom of the robot body enable the robot to move flexibly at the bottom of the vehicle and reach different inspection positions. The cylinder drives the rotating block to move, which in turn drives the T-shaped slider to slide, thereby causing the support plate to rotate. The camera fixed on the support plate then performs multi-directional inspection, thus overcoming the limitation of traditional inspection methods that can only inspect from a single angle. It can quickly and comprehensively inspect the bottom of the vehicle, greatly improving inspection efficiency and comprehensiveness.

[0025] 2. In this utility model, the light source plate in the cleaning mechanism provides sufficient illumination for the camera, ensuring the clarity of the captured image and helping to improve the accuracy of the inspection. The electric push rod pushes the electric motor to move upward, and the electric motor drives the rotating plate to rotate, which in turn causes the square block to drive the cleaning brush to rotate. The cleaning brush cleans the dust and other impurities on the surface of the light source plate, ensuring the light quality during inspection, thereby ensuring the accuracy of the inspection results. Furthermore, by avoiding the corrosion of the light source plate and other equipment by dust and other impurities, it also helps to extend the service life of the equipment.

Detailed Implementation

[0032] 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.

[0033] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a locomotive body inspection robot, including a body 1, which is the main frame of the entire inspection robot and provides the mounting base for other components. Two connecting frames 2 are fixedly connected to the left and right sides of the body 1, respectively. An adjustment and retraction mechanism is rotatably connected inside the connecting frames 2. A cleaning mechanism is fixedly connected to the top of the body 1. Wheels 13 are rotatably connected to the four corners of the bottom of the body 1. Through the rotation of the wheels 13, the body 1 can move under the locomotive, making it convenient for the robot to reach different inspection positions. These wheels are key components for the robot to achieve its movement function. Two cameras 21 are fixedly connected to the top of the support plate 8. The cameras 21 can capture images of the bottom of the locomotive to detect whether there are any problems under the locomotive. These cameras are important devices for obtaining inspection image information.

[0034] The adjustment and retraction mechanism includes multiple rotating seats 4. The inside of the connecting frame 2 is provided with a square groove 3. The outside of the rotating seat 4 is rotatably connected to the inside of the square groove 3. The square groove 3 inside the connecting frame 2 is used to accommodate the rotating seat 4. The connecting frame 2 plays the role of supporting and connecting the adjustment and retraction mechanism with the body 1, ensuring the stability of the entire structure. A cylinder 5 is fixedly connected to the top of the rotating seat 4. The rotating seat 4 is externally rotatably connected to the inside of the square groove 3, serving as the basic connecting component for adjusting the retraction mechanism. This allows the cylinder 5 to rotate around it, providing a flexible rotation point for subsequent actions and ensuring the continuity and coordination of the entire adjustment and retraction action. A rotating block 6 is fixedly connected to the drive end of the cylinder 5. A support plate 7 is rotatably connected to the top of the connecting frame 2. A support plate 8 is fixedly connected to the top of the support plate 7, providing rotational support for the support plate 8. A T-shaped groove 9 is provided at the bottom of the support plate 8. A T-shaped slider 10 is slidably connected to the inner wall of the T-shaped groove 9. The rotating block 6 is externally rotatably connected to the bottom of the T-shaped slider 10. The rotating block 6 is driven by the cylinder 5 to move outward and then interacts with the T-shaped slider 10. The bottom of the T-shaped slider 10 is rotatably connected, converting the linear motion of the cylinder 5 into the sliding motion of the T-shaped slider 10. This causes the support plate 8 to rotate around the top of the connecting frame 2, enabling the camera 21 fixed to the top of the support plate 8 to perform multi-directional inspection. A guide rod 11 is fixedly connected to the inner wall of the T-shaped groove 9. The inner wall of the T-shaped slider 10 is slidably connected to the outer wall of the guide rod 11. A spring 12 is sleeved on the outside of the guide rod 11. The far sides of multiple springs 12 are fixedly connected to the far sides of the inner walls of multiple T-shaped grooves 9, and the near sides of multiple springs 12 are fixedly connected to the far sides of multiple T-shaped sliders 10. The T-shaped slider 10 slides within the T-shaped groove 9. The guide rod 11 provides guidance for the sliding of the T-shaped slider 10, ensuring the accuracy of the sliding direction. The spring 12 is sleeved on the outside of the guide rod 11. When the T-shaped slider 10 slides, it is compressed and provides restoring force when the retraction mechanism is reset, ensuring that the structure can be smoothly retracted.

[0035] Reference Figure 1 , Figure 2 and Figure 4The cleaning mechanism includes two light source plates 14, the bottom ends of which are fixedly connected to the left and right sides of the top of the body 1. The light source plates 14 provide illumination for the camera 21, ensuring sufficient light during inspection so that the camera 21 can capture clear images, which helps to improve the accuracy of the inspection. The top of the body 1 is provided with a receiving groove 15, the bottom end of which is fixedly connected to an electric push rod 16. The drive end of the electric push rod 16 is fixedly connected to an electric motor 17, and the drive end of the electric motor 17 is fixedly connected to a rotating plate 18. The outer wall of the rotating plate 18 is slidably connected to the inner wall of the receiving groove 15. The receiving groove 15 provides space for the electric push rod 16, electric motor 17, rotating plate 18 and other components, ensuring that the cleaning mechanism has a compact structure. Square blocks 19 are fixedly connected to the bottom left and right sides of the rotating plate 18. A cleaning brush 20 is fixedly connected to the bottom of the square block 19. The bottom side of the cleaning brush 20 contacts the top side of the light source plate 14 and the bottom inner wall of the receiving groove 15. When the electric push rod 16 is turned on, it generates power to drive the electric motor 17 to move upward. This is the starting power source for the cleaning brush 20 to move up and down to clean the light source plate 14. Turning on the electric motor 17 can drive the rotating plate 18 to rotate, thereby transmitting power to the square blocks 19, which in turn drives the cleaning brush 20 to rotate. This is the power source for the cleaning brush 20 to rotate and clean. When the square blocks 19 rotate, the cleaning brush 20 cleans the surface of the light source plate 14, removing dust and other impurities to avoid affecting the inspection quality.

[0036] Working principle: First, the inspection robot is placed at the bottom of the vehicle. The wheels 13 enable the robot body 1 to move. By activating the cylinder 5, power is generated to drive the rotating block 6 to move outward. This movement of the rotating block 6 causes the T-shaped slider 10 to slide within the T-shaped groove 9 and compress the spring 12. The sliding of the T-shaped slider 10, combined with the rotation of the support plate 7, drives the support plate 8 to rotate around the top of the connecting frame 2. The rotation of the support plate 8 drives the camera 21 to perform multi-directional inspection, thus achieving a comprehensive inspection of the bottom of the vehicle. Furthermore, when the robot is not in use, the support plate 8 can be retracted to reduce space occupation.

[0037] By activating the electric push rod 16, power is generated to drive the electric motor 17 to move upward. The movement of the electric motor 17 drives the rotating plate 18 to move upward. Then, the electric motor 17 drives the rotating plate 18 to rotate, which in turn drives the square block 19 to rotate. The rotation of the square block 19 drives the cleaning brush 20 to rotate, thus cleaning the surface of the light source plate 14 and carefully wiping away dust and other impurities to prevent dust and other impurities from causing light shadows or light spots that affect the inspection quality.

[0038] 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.
