Specific implementation

[0022] In order to further explain the technical means and effects taken by the utility model to achieve the predetermined utility model purposes, the specific implementation, structure, features and effects according to the utility model are described in detail as follows by combining with the drawings and preferred embodiments.

[0023] Referring to the drawings: a kind of inspection vehicle that can change travel width is disclosed in the embodiment, including car body 1, guide wheel 2 and driving wheel 3 installed on car body 1, the inspection vehicle in the embodiment, when using, by driving wheel 3 drive and then drive guide wheel 2 and car body 1 move;In order to enter deep place inspection through hole or pipeline narrow passage, such as Figures 1-3As shown, this embodiment designs a deformable inspection vehicle structure; specifically, the guide wheel 2 in this embodiment includes a first drive device 4 fixedly mounted on the vehicle body 1, a support part 5 mounted on the first drive device 4 and driven to rotate by the first drive device 4, and a first wheel body 6 rotatably connected to the support part 5; in use, the first drive device 4 drives the support part 5 to rotate the first wheel body 6 to the side away from or closer to the vehicle body 1 to change the lateral travel width of the inspection vehicle; in this embodiment, the first drive device 4 is a servo motor, wherein, as Figure 1 As shown, in this embodiment, a pair of guide wheels 2 are respectively arranged on the left and right sides of the vehicle body 1. When driving in the normal position, the guide wheels 2 are in a stable driving state with their extensions outwards; as Figure 2 As shown, when it is necessary to pass through a narrow space, the servo motor is controlled to rotate, thereby causing the support part 5 and the first wheel 6 to rotate and deform towards the side closer to the vehicle body 1. As a result, when traveling relative to the normal position, the lateral travel width of the inspection vehicle is reduced, which makes it easier for the inspection vehicle to pass through the narrow area. Conversely, after the inspection vehicle passes through the narrow area, the first drive device 4 drives the support part 5 and the first wheel 6 to rotate away from the vehicle body 1, so that the inspection vehicle returns to its original stable driving state.

[0024] Furthermore, in order to further reduce the driving width of inspection vehicles when entering narrow areas, such as Figure 3 As shown, in this embodiment, the vehicle body 1 includes a mounting body 1-1 and wheel mounting seats 1-2 rotatably connected to the front and rear ends of the mounting body 1-1 and driven to rotate by a second drive device 7. The first drive device 4 is fixed to the front wheel mounting seat 1-2, and the output shaft of the servo motor extends downward through the front wheel mounting seat 1-2 and is fixedly connected to the support part 5; furthermore, as Figure 1 As shown, the support part 5 in this embodiment includes a rotating part 5-1 that extends downward from the servo output shaft and a connecting part 5-2 that extends outward from the rotating part 5-1. The first wheel 6 is rotatably connected to the outer end of the connecting part 5-2. Correspondingly, in this embodiment, a pair of guide wheels 2 are respectively positioned on the front wheel mounting base 1-2. Furthermore, as... Figure 7 As shown, in this embodiment, the support parts 5 on the left and right guide wheels 2 are staggered front and back. When the support parts 5 rotate and deform towards the side closer to the vehicle body 1, the connecting parts 5-2 can rotate at a larger angle, which in turn makes the lateral travel width of the inspection vehicle smaller after the guide wheels 2 on the inspection vehicle rotate and deform.

[0025] In this embodiment, the servo motor is mounted on the front wheel mounting seat 1-2, and the drive wheel 3 is mounted on the rear wheel mounting seat 1-2. The second drive device 7 drives the wheel mounting seats 1-2 to rotate upwards or downwards to change the vertical travel width of the inspection vehicle; specifically, as shown... Figure 4As shown, the second drive device 7 in this embodiment can be an electric push rod with its fixed end rotatably connected to the mounting body 1-1. In this embodiment, the electric push rod has two parts corresponding to the front and rear wheel mounting seats 1-2 respectively. The piston end of the electric push rod is rotatably connected to the wheel mounting seats 1-2 to push the wheel mounting seats 1-2 to rotate. When the inspection vehicle needs to pass through a narrow area, the first drive device 4 drives the support part 5 and the first wheel body 6 to rotate and deform to the side away from the vehicle body 1. Then, the second drive device 7 drives the front and rear wheel mounting seats 1-2 to rotate upward to a position horizontal with the mounting body 1-1. At this time, the lower ends of the guide wheel 2 and the drive wheel 3 are lower than the vehicle body 1 and in contact with the ground, thereby reducing the vertical travel width of the inspection vehicle. Based on the original reduction in the lateral travel width, the vertical travel width of the inspection vehicle is also further reduced, so that the inspection vehicle can enter a narrower space.

[0026] Specifically, such as Figure 1 and Figure 5 As shown, in this embodiment, the front wheel mounting seat 1-2 has a first rotating shaft 8 protruding outwards to the left and right ends at its middle end. The first rotating shaft 8 is rotatably connected to the mounting body 1-1, thereby allowing the front wheel mounting seat 1-2 to be rotatably connected to the front end of the mounting body 1-1 via the first rotating shaft 8. Simultaneously, a guide wheel 2 is disposed on the wheel mounting seat 1-2 below the first rotating shaft 8, and the piston end of the front electric actuator is rotatably connected to the wheel mounting seat 1-2 below the first rotating shaft 8. Therefore, when entering a narrow area, the front electric actuator extends outwards, pushing the front wheel mounting seat 1-2 to rotate upwards around the first rotating shaft 8. Furthermore, as... Figure 2 and Figure 3 As shown, in this embodiment, a camera 9 is installed above the first rotating shaft 8 and is mounted in the wheel mounting seat 1-2. The front end of the mounting body 1-1 has a receiving cavity 10. The second driving device 7 drives the front wheel mounting seat 1-2 to rotate upward so that the wheel mounting seat 1-2 rotates into the receiving cavity 10. Thus, when the inspection vehicle needs to enter a narrow area, the camera 9 can be retracted into the receiving cavity 10. When passing through the narrow area, the camera 9 can return to its original shooting position to avoid the camera 9 colliding with the outside world and being damaged when entering the narrow area.

[0027] Similarly, in this embodiment, the upper end of the rear wheel mounting seat 1-2 is provided with a rotating connecting part 11 that protrudes outward to both the left and right ends. A second rotating shaft 12 that protrudes outward is mounted on the rotating connecting part 11. The second rotating shaft 12 is rotatably connected to the rear end of the mounting body 1-1. The rear wheel mounting seat 1-2 is rotatably connected to the mounting body 1-1 through the second rotating shaft 12. The drive wheel 3 is located on the wheel mounting seat 1-2 below the second rotating shaft 12. The lower end of the rotating connecting part 11 is provided with a drive connecting part 13 that is rotatably connected to the piston end of the rear electric push rod. When it is necessary to enter a narrow area, the rear electric push rod extends outward and pushes the rear wheel mounting seat 1-2 to rotate upward around the second rotating shaft 12 through the drive connecting part 13, thereby causing the drive wheel 3 to rotate upward relative to the mounting body 1-1, reducing the vertical travel width of the inspection vehicle.

[0028] Going a step further, such as Figure 3 As shown, the drive wheel 3 in this embodiment includes a drive motor installed in the rear wheel mounting seat 1-2 and a second wheel body 3-1 installed on the output shaft of the drive motor. In use, the drive motor drives the second wheel body 3-1 to rotate, thereby driving the inspection vehicle to move.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
