Therefore, track laser rust removal robotic arms have broad application prospects in the rail transit field. They can be used for rust removal and maintenance of railway rails, improving the welding strength and reliability of rails, and eliminating safety hazards. Track laser rust removal robotic arms are efficient and environmentally friendly rust removal equipment. They combine laser technology and the flexibility of robotic arms to achieve precise and efficient removal of rust layers from track surfaces.

[0003] Typically, a track laser rust removal robotic arm needs to be fixed to a track inspection vehicle, which provides support and stability to ensure that the robotic arm maintains a stable posture during the rust removal process. However, most track inspection vehicles cannot be adjusted according to the width of the track. Therefore, a track laser rust removal robotic arm has been proposed to solve the above problems. Utility Model Content

This solves the problem that the conventional track laser rust removal robotic arm needs to be fixed to the track inspection vehicle, and the vehicle needs to provide support and stability to ensure that the robotic arm can maintain a stable posture during the rust removal process. However, most track inspection vehicles cannot be adjusted according to the width of the track.

[0018] 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.

[0019] Please see Figure 1-3 The track laser rust removal robotic arm in this embodiment includes a fixed base 1, a connecting plate 2 fixedly installed on the outside of the fixed base 1, a roller 3 connected to the outside of the connecting plate 2, a robotic arm body 4 connected to the outside of the connecting plate 2, a laser generator 5 connected to the bottom of the robotic arm body 4, and an adjustment structure 6 provided on the outside of the fixed base 1.

[0020] The adjustment structure 6 includes a connecting box 601. The connecting box 601 is movably mounted on the outside of the fixed base 1. A control rod 602 is rotatably mounted inside the connecting box 601. A gear 603 is fixedly mounted on the outside of the control rod 602. A fixing block 604 is fixedly mounted on the outside of the connecting box 601. A screw 605 is threadedly connected inside the fixing block 604. A clamping plate 606 is rotatably mounted on the outside of the screw 605. A turntable 607 is fixedly mounted on the outside of the control rod 602. A swing rod 608 is fixedly mounted on the outside of the turntable 607. A sliding groove 609 is opened inside the swing rod 608. A slider 610 is slidably mounted inside the sliding groove 609. A connecting rod 611 is fixedly mounted on the outside of the slider 610. A limit block 612 is fixedly mounted inside the connecting box 601.

[0021] exist Figure 1 In the process, a laser head is installed on the outside of the laser generator 5. The laser head is brought close to the track by the robotic arm body 4. The laser beam is focused on the metal surface and produces a strong thermal and photomechanical effect on the rust layer on the metal surface, causing the rust layer to heat up rapidly and undergo physical or chemical changes, eventually vaporizing or melting, thus completing the rust removal on the track surface.

[0022] exist Figure 1 In this design, both the laser generator 5 and the laser head are existing technologies. By using the robotic arm body 4 in conjunction with the laser generator 5 to remove rust from the track, the accuracy of rust removal can be improved. At the same time, it can be applied to track surfaces of various complex shapes to achieve all-round rust removal.

[0023] exist Figure 1 In this process, the robotic arm body 4 is a current technology. Through the unique operational flexibility and high precision of the robotic arm body 4, it can replace manual labor in removing rust from the surface of the track and greatly improve the efficiency of rust removal.

[0024] During implementation, the following steps are performed: When the roller 3 is in contact with the top of the track, the roller 3 will drive the fixed seat 1 to move on the surface of the track. The robotic arm body 4 drives the laser generator 5 to move closer to the track. When the fixed seat 1 moves, the laser generator 5 can perform laser rust removal on the surface of the track. The distance between the two fixed seats 1 can be adjusted by rotating the gear 603. Finally, the screw 605 is rotated to fix the gear 603 through the clamping plate 606 to maintain the distance between the two fixed seats 1.

[0025] In summary, this track laser rust removal robotic arm, when the roller 3 is in contact with the top of the track, will cause the fixed seat 1 to move on the surface of the track. The robotic arm body 4 will drive the laser generator 5 to move closer to the track. As the fixed seat 1 moves, the laser generator 5 will perform laser rust removal on the surface of the track. When it is necessary to adjust the distance between the fixed seats 1 according to the width of different tracks, rotating the gear 603 will drive the control rod 602 and the turntable 607 to rotate. When the slide 609 moves, it will drive the connecting rod 611 to move through the slider 610, thereby adjusting the distance between the two fixed seats 1. Finally, rotating the screw 605 will fix the gear 603 through the clamping plate 606 to maintain the distance between the two fixed seats 1. This solves the problem that the track laser rust removal robotic arm usually needs to be fixed to the track inspection vehicle to provide support and stability for the robotic arm and ensure that the robotic arm can maintain a stable posture during the rust removal process. However, most track inspection vehicles cannot adjust according to the width of the track.
