Description

Technical Field

[0001] This utility model relates to an inspection robot, specifically a railway line inspection robot. Background Technology

[0002] Railway transportation is an irreplaceable part of the transportation network, and the importance of railway safety cannot be ignored. In order to ensure the safe use of rails and prevent problems before they occur, it is necessary to conduct regular flaw detection on the rails to detect whether there are internal defects such as cracks. Ultrasonic flaw detection is a commonly used railway track inspection flaw detection technology.

[0003] A railway inspection robot is proposed in the prior art with announcement number CN216886658U. It uses brushes on the surface of the track-walking wheels to clean foreign objects on the track, thus avoiding the impact of foreign objects on the accuracy of the inspection.

[0004] However, the existing railway inspection robots described above use brushes on the surface of the track-walking wheels, but if there are foreign objects such as stones on the track, the track-walking wheels may not be able to move normally. Therefore, this application proposes a railway dedicated line inspection robot to solve this problem. Utility Model Content

[0005] The purpose of this utility model is to provide a railway line inspection robot to solve the problem mentioned in the background art that the existing railway inspection robot, which uses brushes on the surface of the track walking wheels, may not be able to move normally if there are foreign objects such as stones on the track.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A railway line inspection robot includes a housing. A mounting base is provided on the top of the housing, and a camera is fixedly mounted on the mounting base. An ultrasonic generator and an ultrasonic sensor are fixedly mounted on the bottom of the housing. A transmission antenna is fixedly mounted on the top of the housing. First and second mounting plates are fixedly mounted at the four corners of the bottom of the housing. A motor is fixedly mounted on one side of the second mounting plate. The output shafts of the two front motors are fixedly mounted with second rotating shafts, and the output shafts of the two rear motors are fixedly mounted with first rotating shafts. Rollers are provided on the outer sides of both the first and second rotating shafts. A fixing plate is fixedly mounted on the front sides of the two sets of first and second mounting plates. A fourth rotating shaft is rotatably mounted on the bottom of the fixing plate. A second bevel gear is fixedly mounted on the outer side of the fourth rotating shaft. A third rotating shaft is rotatably mounted on one side of the fixing plate. A first bevel gear is fixedly mounted on the outer side of the third rotating shaft. Sprockets are fixedly mounted on the outer sides of both the third and second rotating shafts. A chain is sleeved on the outer sides of the two sprockets. The first and second bevel gears mesh. A cleaning roller is fixedly mounted at the bottom end of the fourth rotating shaft.

[0008] As a further improvement of this utility model, the outer side of the second rotating shaft is provided with an external thread.

[0011] As a further improvement of this utility model, a storage battery is fixedly installed inside the housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a motor to drive the first and second rotating shafts to rotate, thereby moving the rollers. At the same time, during the rotation of the second rotating shaft, the chain and sprocket will mesh and drive, thereby driving the fourth rotating shaft. The rotation of the fourth rotating shaft will drive the sweeping roller to rotate at a higher speed. The sweeping roller is located in front of the rollers and sweeps away foreign objects such as stones in advance, thereby avoiding affecting the movement of the rollers.

[0014] 2. This utility model adjusts the position of the roller by rotating the nut to slide the roller. The change in the position of the roller allows the device to adapt to tracks of different widths, thereby improving the adaptability of the device. Attached Figure Description

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.

[0021] Please see Figures 1-4In this embodiment of the utility model, a railway line inspection robot includes a housing 2. A mounting base is provided on the top of the housing 2, and a camera 1 is fixedly mounted on the mounting base. An ultrasonic generator 18 is fixedly mounted on the bottom of the housing 2, and an ultrasonic sensor 21 is fixedly mounted on the bottom of the housing 2. A transmission antenna is fixedly mounted on the top of the housing 2. A first mounting plate 13 and a second mounting plate 17 are fixedly mounted at each of the four corners of the bottom of the housing 2. A motor 7 is fixedly mounted on one side of the second mounting plate 17. The output shafts of the two front motors 7 are each fixedly mounted with a second rotating shaft 11, and the output shafts of the two rear motors 7 are each fixedly mounted with a first rotating shaft 5. The first rotating shaft 5 and the second... Rollers 6 are provided on the outer side of the two rotating shafts 11. Fixing plates 3 are fixedly installed on the front sides of the two sets of first mounting plates 13 and second mounting plates 17. A fourth rotating shaft 20 is rotatably installed at the bottom of the fixing plate 3. A second bevel gear 10 is fixedly installed on the outer side of the fourth rotating shaft 20. A third rotating shaft 15 is rotatably installed on one side of the fixing plate 3. A first bevel gear 8 is fixedly installed on the outer side of the third rotating shaft 15. Sprockets 12 are fixedly installed on the outer sides of the third rotating shaft 15 and the second rotating shaft 11. A chain 14 is sleeved on the outer side of the two sprockets 12. The first bevel gear 8 meshes with the second bevel gear 10. A cleaning roller 9 is fixedly installed at the bottom end of the fourth rotating shaft 20.

[0022] The outer side of the second rotating shaft 11 is provided with an external thread. Two nuts 16 are connected to the outer side of the second rotating shaft 11 through the external thread. The two nuts 16 are located on both sides of the roller 6 and abut against the surface of the roller 6. By adjusting the position of the roller 6, the device can be adapted to tracks of different widths.

[0023] The battery 4 is fixedly installed inside the housing 2. The front of the housing 2 is designed to be open. Several ventilation slots 19 are opened on one side of the housing 2 for heat dissipation of the battery 4.

[0024] The motor 7, camera 1, ultrasonic generator 18 and ultrasonic sensor 21 are all electrically connected to the battery 4 and the transmission antenna simultaneously via wires. The transmission antenna is electrically connected to an external controller via a wireless connection module.

[0025] The working principle of this utility model is as follows:

[0026] In use, the distance between the left and right rollers 6 is adjusted according to the width of the track. This is done by rotating the nut 16 on the side of the roller 6 that moves in that direction and sliding the roller 6. Once the distance is adjusted appropriately, the nut 16 on the side away from the direction of the roller 6's movement is rotated. The two nuts 16 clamp the roller 6, fixing it in place. This allows the device to adapt to tracks of different widths. The motor 7 drives either the first rotating shaft 5 or the second rotating shaft 11 to rotate. The first and second rotating shafts 5 and 11 then rotate the rollers 6, allowing the device to move on the track. During the rotation of the second rotating shaft 11 by the motor 7, the sprocket 12 rotates. The sprocket 12 then drives another sprocket 12 via a chain 14. During the rotation of wheel 12, the third rotating shaft 15 will rotate, which in turn will drive the first bevel gear 8 to rotate. The first bevel gear 8 will then drive the second bevel gear 10 to rotate. The second bevel gear 10 will then drive the fourth rotating shaft 20 to rotate, which in turn will drive the cleaning roller 9 to rotate. The cleaning roller 9 is located in front of the roller 6. The high-speed rotating cleaning roller 9 will first clean the track in front of the roller 6. At this time, foreign objects such as stones on the track will be removed first, thus avoiding affecting the movement of the roller 6. During the movement of the device, the condition of the track surface is observed through camera 1, and sound waves are emitted to the track through ultrasonic generator 18. The sound waves are received through ultrasonic sensor 21, and the data is transmitted through antenna, thereby completing the inspection of the track.

[0027] Although the present invention 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 invention should be included within the protection scope of the present invention.
