[0018] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0019] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0021] Reference Figure 1-4 The rail inspection robot driving device includes a power motor 4 and a folding track 6. A load-bearing plate 1 is fixedly arranged at one end of the power motor 4. Load-bearing plates 1 are fixedly arranged at both sides of the folding track 6. The load-bearing plate 1 provides a platform for the installation of the power motor 4 and the folding track 6, which is convenient for the combined use of the power motor 4 and the folding track 6. The bottom surface of the load-bearing plate 1 at one end of the folding track 6 is bolted to the top surface of the load-bearing plate 1 at one end of the power motor 4. The output shaft of the power motor 4 passes through the surface of the load-bearing plate 1 and is engaged with a driving gear 11. The power structure of the entire device is the power motor 4. The power motor 4 rotates and drives the driving gear 11 to rotate through the output shaft. The driving gear 11 is rotated and transmitted through the transmission belt 13 meshing on the surface, thereby driving the driven gear 12 meshing inside the top of the transmission belt 13 to rotate. Since the driven gear 12 is connected to the end of the threaded transmission rod 7, the threaded transmission rod 7 is threadedly connected to the surface of the guide slide 10. Therefore, when the driven gear 12 rotates, the threaded transmission rod 7 rotates to make the guide slide 10 move linearly on the surface of the threaded transmission rod 7, thereby realizing the left and right movement of the guide slide 10.

[0022] A threaded transmission rod 7 is provided inside the folding track 6, and a guide slide 10 is connected to the surface of the threaded transmission rod 7. One end of the threaded transmission rod 7 penetrates the surface of the load-bearing plate 1 and is connected to a driven gear 12. A transmission toothed belt 13 is externally meshed between the driven gear 12 and the driving gear 11. The top of the horizontally placed power motor 4 is connected to the folding track 6. The output shaft of the power motor 4 drives the driving gear 11 to rotate. Under the meshing transmission of the transmission toothed belt 13, the driven gear 12 at the other end of the transmission toothed belt 13 is driven to rotate, and the threaded transmission rod 7 connected to the driven gear 12 is indirectly driven to rotate, so that the guide slide 10 on the surface of the threaded transmission rod 7 is displaced. The guide slide 10 is indirectly driven to move by the rotation of the power motor 4, which saves the horizontal space occupied by the entire equipment, reduces the volume of the entire equipment, is convenient for multi-point installation and use, has a simple structure, and is convenient for practical use.

[0023] A guide seat 8 is fixedly provided on the inner bottom surface of the folding track 6, and guide limit grooves 9 are opened on both sides of the guide seat 8, and the guide limit grooves 9 are blind grooves. The two sides of the bottom surface of the guide slide 10 are slidably engaged with the guide limit grooves 9. The horizontal center line of the top surface of the folding track 6 coincides with the horizontal center line of the top surface of the power motor 4. The power motor 4 is placed horizontally. The guide limit grooves 9 provide a guiding basis for the movement of the guide slide 10 on the surface of the threaded transmission rod 7. When the guide slide 10 slides along the threaded transmission rod 7, the bottom end of the guide slide 10 slides synchronously along the guide limit grooves 9, and the guide limit grooves 9 limit the bottom end of the guide slide 10 to prevent the bottom end of the guide slide 10 from being misaligned when the guide slide 10 slides.

[0024] The horizontal center line of the top surface of the threaded transmission rod 7 coincides with the horizontal center line of the top surface of the power motor 4, and the vertical center line of the surface of the driven gear 12 coincides with the vertical center line of the surface of the driving gear 11, thereby ensuring that the driving gear 11 and the driven gear 12 maintain a unified center line during transmission, so that the driving gear 11 can drive the driven gear 12 to rotate through the transmission belt 13. Positioning screw seats 2 are welded on both sides of the bottom surface of the load-bearing plate 1 at the end of the power motor 4 and on both sides of the bottom surface of the load-bearing plate 1 at the end of the folding track 6 away from the power motor 4. Positioning screw seats 2 are internally threadedly connected with positioning bolts 3, and the entire equipment is connected to the external processing table surface through the positioning screw seats 2 and the positioning bolts 3.

[0025] The side surface of the load-bearing plate 1 at the end of the folding track 6 and the side surface of the load-bearing plate 1 at the end of the power motor 4 are coplanar, and the outer side surfaces of the load-bearing plate 1 are connected at rounded corners to provide an installation platform for the transmission of the driven gear 12 and the driving gear 11. The end of the threaded transmission rod 7 close to the driven gear 12 and the end of the output shaft of the power motor 4 are threadedly engaged with a positioning ball 5. The output shaft of the power motor 4 and the threaded transmission rod 7 are both slidably connected to the surface of the load-bearing plate 1. The positioning ball 5 is provided to prevent the ends of the threaded transmission rod 7 and the output shaft ends of the power motor 4 from being directly damaged, resulting in damage to the driving gear 11 and the driven gear 12. Through the provision of the positioning ball 5, the force is dispersed when the ends of the threaded transmission rod 7 and the output shaft ends of the power motor 4 are subjected to force. Specific embodiment 2:

[0027] Reference Figure 1-4 The threaded transmission rod 7 and the center position of the driven gear 12 can be connected by threaded installation or protrusion and slot installation. The end of the threaded transmission rod 7 away from the driven gear 12 is plugged into the surface of the load-bearing plate 1. The load-bearing plate 1 provides support for the threaded transmission rod 7. The load-bearing plate 1 and the threaded transmission rod can be disassembled. The connection between the threaded transmission rod 7 and the driven gear 12 is a detachable connection, which is convenient for disassembly of the threaded transmission rod 7 and the guide groove.
