[0030] The utility model application embodiment provides an automatic track changing mechanism for a side track robot to solve the technical problem in the prior art that the track robot is set up at a commanding point in a tunnel and is difficult to maintain when vehicles are passing. The following will be explained in conjunction with the accompanying drawings.

[0031] See also Figures 1 to 7In this embodiment, the automatic track changing mechanism of the side rail robot provided by the present application includes a sliding rail 1 and a moving rail 2, the sliding rail 1 includes a sliding rail 10, a slider 11, a slide groove 12 and a chain 14, the sliding rail 10 and the slide groove 12 are fixedly connected by mounting blocks 13 at both ends, the slider 11 is slidably connected to the sliding rail 10, and the moving rail 2 is connected to the slider 11; a first gear 120 and a fixed column 121 are arranged in the slide groove 12, a second gear 111 and a fixed block 110 are arranged on a side surface of the slider 11 away from the moving rail 2, one end of the chain 14 is fixed on the fixed block 110 and the end of the chain 14 is connected to the fixed column 121, the chain 14 is meshed and connected with the first gear 120 and the second gear 111 respectively, and the end of the other end is connected to the telescopic rod 30, the mounting block 13 is provided with a through hole 130, and the telescopic rod 30 passes through the through hole 130 and is connected to the servo motor 3 installed on the mounting block 13.

[0032] In this embodiment, the sliding rail 1 is the basic part of the entire automatic track changing mechanism, and is mainly used to provide a stable sliding rail 1, so that the mobile rail 2 (connected to the robot 6 or other parts that need to be moved) can move along a predetermined path. The sliding rail 1 is composed of a sliding rail 10, a slider 11, a slide 12 and a chain 14. The sliding rail 10 is the main sliding path, and the slider 11 is slidably connected to the sliding rail 10 to ensure stable guidance during the movement. The first gear 120 and the fixed column 121 set in the slide 12, and the meshing of the chain 14 with the first gear 120 and the second gear 111 together constitute a sliding drive mechanism. The mobile rail 2 is a component connected to the slider 11, which is mainly used to carry the robot 6 or other equipment that needs to be moved. When the slider 11 of the sliding rail 1 slides on the sliding rail 10, the mobile rail 2 will move accordingly, thereby driving the robot 6 or the equipment to move to a new position. The sliding rail 1 and the moving rail 2 are connected by the slider 11, which ensures that when the sliding rail 1 moves, the moving rail 2 can stably and accurately follow the movement of the sliding rail 1, ensuring that the robot 6 or the device can move smoothly and reliably from one position to another. The servo motor 3 is used to provide power so that the moving rail 2 can slide on the sliding member.

[0033] In the above embodiment, the telescopic rod 30 is driven by the servo motor 3, and the telescopic movement of the telescopic rod 30 drives the movement of the chain 14. Since the chain 14 is meshed and connected with the first gear 120 and the second gear 111 respectively, when the chain 14 moves, it will drive the rotation of the first gear 120 and the second gear 111. Since the first gear 120 is fixed in the slide 12, its rotation will be converted into the linear motion of the slide 12 (but since the slide 12 itself does not move, it is actually converted into the linear motion of the chain 14 here). At the same time, the rotation of the second gear 111 will drive the slider 11 to slide on the slide rail 10, and then drive the moving rail 2 connected to the slider 11 to move. In order to realize the automatic track change of the robot 6 or the equipment on the slide rail 1.

[0034] In the above embodiment, the telescopic rod 30 is driven by the servo motor 3, thereby pulling the chain 14. The chain 14 is meshed with the first gear 120 and the second gear 111, thereby driving the slider 11 to move on the slide rail 10. The movement of the slider 11 further drives the moving rail 2 to move, realizing the function of automatic track change. When applied to a tunnel, the robot 6 can be automatically lowered to a maintainable height at both ends of the fixed track by the robot's own gravity, which is convenient for technicians to maintain. After the maintenance is completed, the servo motor 3 drives the moving rail 2 to move up and brings the robot 6 back to the working track, which can effectively solve the technical problem that the track robot 6 is set up at the commanding height of the tunnel in the prior art, and it is difficult to maintain the track robot 6 when vehicles are passing.

[0035] See also Figures 1 to 7 In one embodiment, the slider 11 includes a base 112, a mounting cover 113 and a connecting block 114. The base 112 is provided with a first groove 115. The mounting cover 113 covers the first groove 115 to form a through hole. The slide rail 10 passes through the through hole and is slidably connected to the slider 11. The connecting block 114 is connected to the movable rail 2. When the slider 11 moves along the slide rail 10, it drives the movable rail 2 to move.

[0036] In this embodiment, the base 112 is the basic structure of the slider 11, which is used to support and fix other components. The first groove 115 provided on the base 112 is used to cooperate with the mounting cover 113 to form a through hole, so that the slide rail 10 can pass through and be slidably connected thereto. The through hole allows the slide rail 10 to pass through, ensuring that the slider 11 can slide stably on the slide rail 10. The presence of the mounting cover 113 not only enhances the structural strength of the slider 11, but also ensures that the connection between the slide rail 10 and the slider 11 is tight and reliable. When the mounting cover 113 covers the first groove 115, it can be fixed with bolts.

[0037] In the above embodiment, when the servo motor 3 drives the chain 14 to move through the telescopic rod 30, the meshing relationship between the chain 14 and the first gear 120 and the second gear 111 causes the slider 11 to slide on the slide rail 10. Since the connecting block 114 is fixedly connected to the movable rail 2, the movement of the slider 11 will drive the movable rail 2 to move together. This movement mode is continuous and smooth, which can ensure that the robot 6 or other equipment remains stable and safe during the movement. In the automatic track changing mechanism, the slider 11 achieves a stable connection with the slide rail 10 and synchronous movement with the movable rail 2 through the coordinated work of the three parts of the base 112, the mounting cover 113 and the connecting block 114. Not only the reliability and stability of the mechanism are improved, but also the accuracy and efficiency of the automatic track changing are ensured.

[0038] Please continue reading Figures 1 to 7 In one embodiment, the bottom of the slide groove 12 is recessed downward to form a second groove 122, the end of the telescopic rod 30 is bent toward a side wall of the second groove 122, and the chain 14 extends along the side wall of the second groove 122 and is connected to the end of the telescopic rod 30.

[0039] In this embodiment, the second groove 122 formed by the bottom of the slide 12 being concave downward is mainly used to provide a space to accommodate and fix the connection part between the chain 14 and the telescopic rod 30, so that the entire transmission mechanism is more compact and orderly, and unnecessary friction and interference are reduced. The end of the telescopic rod 30 is bent toward the second groove 122, so that the telescopic rod 30 can be better connected to the chain 14 and can adapt to the movement trajectory of the chain 14. When the servo motor 3 drives the telescopic rod 30 to extend and retract, the bent end can guide the movement of the chain 14 more smoothly, reducing the possible jamming or distortion of the chain 14 when reversing.

[0040] In the above embodiment, by providing the second groove 122 at the bottom of the slide 12 and connecting the end of the telescopic rod 30 to the chain 14, not only the transmission system of the automatic track-changing mechanism is optimized, but also the operating efficiency and stability of the mechanism are improved. This compact and orderly layout makes the entire mechanism more stable and reliable during operation, and can better meet the needs of the robot 6 or other equipment during the track-changing process.

[0041] See also Figures 1 to 7 In one embodiment, a plurality of mounting holes 123 are respectively provided along the two side walls at the bottom of the second groove 122 for fixing the slide slot 12 .

[0042] In this embodiment, the mounting hole 123 can be used to securely fix the slide 12 in a suitable position using bolts, screws or other fasteners, thereby increasing the stability of the slide 12, preventing the slide 12 from moving or shaking due to vibration or external force, and making the installation and removal of the slide 12 easier, thus facilitating maintenance and replacement.

[0043] Please continue reading Figures 1 to 7 In one embodiment, both side surfaces and upper and lower end surfaces of the movable rail 2 are provided with slideways 20 for the movement of the robot 6 .

[0044] In this embodiment, the slide 20 provides a clear moving path for the robot 6, ensuring that the robot 6 can move stably and accurately on the moving rail 2. Guided by the slide 20, the robot 6 can move accurately from one position to another, avoiding the risk of deviating from the track or misoperation. The slide 20 can bear the weight of the robot 6 and provide necessary support. This allows the robot 6 to remain stable during the movement, and its operating accuracy or safety will not be affected by shaking or vibration. At the same time, slides 20 are provided on both side surfaces and the upper and lower end surfaces of the moving rail 2 to ensure the stable movement of the robot 6 in three-dimensional space. The side slides 20 are usually used to limit the left and right moving range of the robot 6 to prevent it from deviating from the track; while the slides 20 on the upper and lower end surfaces are used to support the weight of the robot 6 and guide it to move forward and backward.

[0045] Please continue reading Figures 1 to 7 In one embodiment, the sliding rail 1 further includes a first limit block 15 , and limit grooves 16 are provided on both sides of the outside of the slide groove 12 , and the first limit block 15 is installed in the limit grooves 16 .

[0046] In this embodiment, the first limit block 15 and the limit groove 16 cooperate to ensure the stable sliding of the slider 11 on the slide rail 10 and prevent it from excessive movement. The first limit block 15 is installed in the limit groove 16 outside the slide groove 12. When the slider 11 slides on the slide rail 10, the first limit block 15 will limit the range of motion of the slider 11 to prevent it from excessive sliding and leaving the slide rail 10. The cooperation between the limit block and the limit groove 16 can ensure the stability of the slider 11 during the sliding process and reduce the sliding deviation caused by vibration or external force. The limit groove 16 is located on both sides of the outside of the slide groove 12, and its shape and size match the first limit block 15. The length of the limit groove 16 extends along the length direction of the slide groove 12, ensuring that the first limit block 15 can adjust its position in the limit groove 16. Ensure that the first limit block 15 can be firmly installed in the limit groove 16 and can provide a stable limiting effect when the slider 11 slides.

[0047] See also Figures 1 to 7In one embodiment, the automatic track changing mechanism of the side rail robot also includes a plurality of fixed rails 4 which are arranged intermittently and in parallel at the same height position, and the interruptions of the movable rail 2 and the fixed rail 4 are of equal length so that the movable rail 2 can be connected to the fixed rail 4.

[0048] In this embodiment, the fixed rail 4, as one of the paths for the robot 6 to move, provides stable support and guidance, ensuring the stability and accuracy of the robot 6 during movement. The fixed rails 4 are intermittently arranged at the same height position, that is, there are gaps or disconnected parts between the fixed rails 4, allowing the mobile rail 2 to connect or disconnect with the fixed rail 4 at these gaps, thereby realizing the track changing function. Multiple fixed rails 4 are arranged in parallel, ensuring that the movement of the robot 6 between different fixed rails 4 can maintain a consistent direction and height, avoiding operational difficulties or errors caused by height changes or direction deviations. The length of the mobile rail 2 is equal to the length of the discontinuity of the fixed rail 4 to ensure that the mobile rail 2 can completely cover and connect to the gap of the fixed rail 4. When the mobile rail 2 slides to the discontinuity of the fixed rail 4, it can be tightly connected to the fixed rail 4 to form a continuous moving path, thereby allowing the robot 6 to switch freely between the fixed rail 4 and the mobile rail 2.

[0049] In the above embodiment, when a track change operation is required, the mobile rail 2 first slides to a position adjacent to the target fixed rail 4 through the driving mechanism of the sliding rail 1, such as the servo motor 3 and the chain 14. Then, the connecting portion of the mobile rail 2, such as the connecting block 114, is aligned and connected with the discontinuity of the target fixed rail 4. After the connection is completed, the robot 6 can move freely between the fixed rails 4 through the mobile rail 2, realizing the function of automatic track change.

[0050] See also Figures 1 to 7 In one embodiment, the automatic track changing mechanism of the side rail robot further includes a second limit block 5 , and the second limit block 5 is arranged parallel to the connection between the fixed rail 4 and the movable rail 2 .

[0051] In the above embodiment, the second limit block 5 is arranged in parallel at the connection between the fixed rail 4 and the movable rail 2 to form a physical limit. When the robot 6 moves on the track, after passing the connection between the fixed rail 4 and the movable rail 2 and stopping at the movable rail 2, the second limit block 6 prevents the robot 6 from sliding sideways due to external force or its own factors.

[0052] The operation process of the automatic track changing mechanism of the side track robot in the utility model patent application is as follows:

[0053] When the robot 6 needs to be maintained, the operation and maintenance or backstage responsible personnel issue the preparation command of the robot 6 through the remote control system. After receiving the command, the robot 6 runs to the lifting track section. At the same time, the travel limit switch of the robot 6 senses that the robot 6 is in place. At this time, the second limit block 5 limits the lifting and lowering ends to prevent the robot 6 from generating relative displacement during the lifting process. The servo motor 3 is started to make the telescopic rod 30 relax the chain 14. The robot 6 lowers the movable rail 2 by its own gravity until it senses the first limit block 15, that is, it reaches the specified position. At this time, the second limit block 5 releases the limit at both ends of the lifting and lowering, and the robot 6 starts to travel along the fixed rail 4 to the corresponding maintenance point. After the maintenance is completed, the robot 6 is remotely or directly controlled to run to the lifting track section, the servo motor 3 is started, and the chain 14 and the first gear 120 and the second gear 111 are driven to rotate through the telescopic rod 30, and the movable rail 2 is raised to the working track, completing the re-commissioning of the robot 6.

[0054] In summary, the automatic track changing mechanism of the side rail robot provided by the utility model comprises a sliding rail 1 and a moving rail 2, wherein the sliding rail 1 comprises a sliding rail 10, a slider 11, a slide groove 12 and a chain 14, wherein the sliding rail 10 and the slide groove 12 are fixedly connected via mounting blocks 13 at both ends, the slider 11 is slidably connected to the sliding rail 10, and the moving rail 2 is connected to the slider 11; a first gear 120 and a fixed column 121 are arranged in the slide groove 12, a second gear 111 and a fixed block 110 are arranged on a side surface of the slider 11 away from the moving rail 2, one end of the chain 14 is fixed to the fixed block 110 and the end of the chain 14 is connected to the fixed column 121, the chain 14 is respectively meshed and connected with the first gear 120 and the second gear 111 and the end of the other end is connected to the telescopic rod 30, the mounting block 13 is provided with a through hole 130, and the telescopic rod 30 passes through the through hole 130 and is connected to the servo motor 3 mounted on the mounting block 13. The utility model drives the telescopic rod 30 through the servo motor 3, thereby pulling the chain 14. The chain 14 is meshed with the first gear 120 and the second gear 111, thereby driving the slider 11 to move on the slide rail 10. The movement of the slider 11 further drives the moving rail 2 to move, realizing the function of automatic track switching. When applied to a tunnel, the robot 6 can be automatically lowered to a maintainable height at both ends of the track, which is convenient for technicians to maintain.
