Description

Technical Field

[0001] This utility model relates to the field of inspection robot technology, and in particular to a drive device for toothed tracks. Background Technology

[0002] Currently, in coal mines, petrochemical plants, and power plants, inspection robots are gradually replacing manual inspections to improve operational efficiency, safety, and stability. These robots primarily rely on cameras mounted on a pan-tilt-zoom (PTZ) platform to obtain high-definition video of the inspection environment, enabling unmanned operation. However, most existing inspection robots use friction-driven systems with rubber-coated wheels and metal tracks. In scenarios such as rain, icy tracks, or steep inclines, the drive wheels can slip, rendering the robot unusable in these conditions. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a drive device for toothed tracks.

[0004] The purpose of this utility model is achieved through the following technical solution: A driving device for a toothed track includes a base plate, a gimbal mounted on the lower surface of the base plate, a mounting plate vertically mounted on the upper surface of the base plate, a drive motor mounted on the mounting plate, the power output end of the drive motor connected to the drive wheel base plate, a plurality of rollers equidistantly mounted on the drive wheel base plate, the rollers meshing with the tooth grooves on the lower surface of the toothed track, the ends of the rollers being installed inside the drive wheel top plate, and a plurality of load-bearing wheels mounted on the upper end of the mounting plate, the load-bearing wheels being located on the upper surface of the toothed track.

[0005] Preferably, the bottom plate of the drive wheel has a plurality of mounting holes a, and the top plate of the drive wheel has mounting holes b corresponding to the mounting holes a, and screws are installed in the mounting holes a and mounting holes b.

[0006] Preferably, limit baffles are provided on both sides of the load-bearing wheel.

[0007] Preferably, a reinforcing plate is also provided between the base plate and the mounting plate.

[0008] This utility model has the following advantages: The utility model drives the drive wheel base plate to rotate through the drive motor, thereby synchronously driving the roller to rotate. Since the roller meshes with the toothed track, the load-bearing wheel moves synchronously above the toothed track, thereby driving the gimbal under the base plate to move forward or backward. Thus, through the meshing transmission between the toothed track and the roller, the robot will not slip in scenarios such as rain, icy track, or climbing steep slopes. Attached Figure Description

[0019] In this embodiment, as Figures 1-3 As shown, a drive device for a toothed track includes a base plate 2, a gimbal mounted on the lower surface of the base plate 2, and a mounting plate 3 vertically mounted on the upper surface of the base plate 2. A drive motor 9 is mounted on the mounting plate 3, and the power output end of the drive motor 9 is connected to a drive wheel base plate 10. Several rollers 6 are evenly mounted on the drive wheel base plate 10, and the rollers 6 mesh with the tooth grooves on the lower surface of the toothed track 1. The ends of the rollers 6 are installed inside the drive wheel top plate 5. Several load-bearing wheels 7 are mounted on the upper end of the mounting plate 3, and the load-bearing wheels 7 are located on the upper surface of the toothed track 1. The drive motor 9 drives the drive wheel base plate 10 to rotate, thereby synchronously driving the rollers 6 to rotate. Since the rollers 6 mesh with the toothed track 1, the load-bearing wheels 7 move synchronously above the toothed track 1, thereby driving the gimbal below the base plate 2 to move forward or backward. Thus, through the meshing transmission between the toothed track 1 and the rollers 6, the robot will not slip in scenarios such as rain, icy tracks, or steep slopes. In this embodiment, the gimbal, toothed track 1, and drive motor 9 are all existing products, and no improvements have been made to them, so they will not be described in detail here.

[0020] Furthermore, the drive wheel base plate 10 has several mounting holes a11, and the drive wheel top plate 5 has mounting holes b corresponding to the mounting holes a11. Screws 8 are installed in the mounting holes a11 and mounting holes b. Specifically, the drive wheel base plate 10 and the drive wheel top plate 5 are located on both sides of the toothed track 1. During the meshing transmission of the rollers 6 on the toothed track 1, the drive wheel base plate 10 and the drive wheel top plate 5 act as limiting plates, thereby restricting the robot's left and right movement relative to the toothed track 1.

[0021] In this embodiment, limit baffles are provided on both sides of the load-bearing wheel 7. Specifically, the main function of the limit baffles is to restrict the robot's left and right movement relative to the toothed track 1.

[0022] Furthermore, a reinforcing plate 4 is provided between the base plate 2 and the mounting plate 3. Specifically, the main function of the reinforcing plate 4 is to enhance the connection strength between the base plate 2 and the mounting plate 3.

[0023] 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.
