Description

Technical Field

[0001] This utility model relates to the field of inspection robot technology, specifically an inspection robot gimbal with lifting function. Background Technology

[0002] As a core component of the inspection robot system, the gimbal enhances the robot's monitoring flexibility and accuracy, enabling it to efficiently serve diverse fields such as power, petrochemicals, transportation, and security. Equipped with a high-definition camera, the gimbal achieves comprehensive, blind-spot-free monitoring of equipment, clearly capturing image or video data. This effectively addresses inspection challenges in complex environments, significantly improving the efficiency and safety of inspection operations.

[0003] Traditional inspection pan-tilt units often rely on fixed-stroke lead screws or reel structures for height adjustment. While this design allows for flexible height adjustment to meet monitoring needs in different scenarios, it also has drawbacks. Specifically, when the inspection robot needs to traverse low-ceilinged spaces, the pan-tilt unit, lacking effective obstacle avoidance or retraction mechanisms, is highly susceptible to collisions with the ceiling. Such hard contact can not only damage the pan-tilt unit's structure, affecting its subsequent monitoring accuracy and stability, but also delay inspection tasks and may even lead to safety accidents. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a gimbal for an inspection robot with lifting and lowering functions, which makes the gimbal less prone to collisions with objects while being able to lift and lower.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gimbal for an inspection robot with lifting function, comprising a gimbal base, a rotating component installed inside the gimbal base, a column rotatably connected to the upper end inside the gimbal base, a threaded rod rotatably connected inside the column, a threaded block threadedly connected to the threaded rod, the threaded block being slidably connected to the column, a lifting motor fixedly connected to the top of the column, the output end of the lifting motor being fixedly connected to the threaded rod, tilt adjustment motors fixedly connected to both ends of the threaded block, and a camera fixedly connected to the output end of the tilt adjustment motor.

[0006] Furthermore, the rotating assembly includes a rotating motor, a drive gear, and tooth blocks. The rotating motor is fixedly connected to the outer wall of the gimbal base, the drive gear is fixedly connected to the output end of the rotating motor, and multiple tooth blocks are fixedly connected to the outer wall of the lower end of the column. The tooth blocks mesh with the drive gear.

[0007] Furthermore, the rotary motor is fitted with a protective shell, which is fixedly connected to the gimbal base.

[0008] Furthermore, rotating grooves are provided on both sides of the lower end of the column, and rotating rings are fixedly connected to both sides of the upper end of the gimbal base, with the rotating rings matching the rotating grooves.

[0009] Furthermore, the upper end of the rotating ring is provided with a notch, the width of which is not less than the width of the threaded block.

[0010] Furthermore, fixing blocks are fixedly connected to both sides of the lower end of the gimbal base, and positioning blocks are fixedly connected to the top of the gimbal base.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] When the height of the camera needs to be adjusted, the lifting motor drives the threaded rod to rotate, and the threaded block connected to the threaded rod will rise or fall accordingly. When the robot is about to enter a low space, in order to avoid the gimbal from colliding with the ceiling, after the threaded block is lowered to the lowest height, the rotating component drives the column to rotate, thereby flattening the column and reducing the overall height of the gimbal, making it less likely to collide with the ceiling.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-4A gimbal for an inspection robot with lifting function includes a gimbal base 1. A rotating component is installed inside the gimbal base 1. A column 7 is rotatably connected to the upper end inside the gimbal base 1. A threaded rod 10 is rotatably connected inside the column 7. A threaded block 12 is threadedly connected to the outside of the threaded rod 10. The threaded block 12 is slidably connected to the column 7. A lifting motor 11 is fixedly connected to the top of the column 7. The output end of the lifting motor 11 is fixedly connected to the threaded rod 10. An angle adjustment motor 13 is fixedly connected to both ends of the threaded block 12. A camera 14 is fixedly connected to the output end of the angle adjustment motor 13.

[0020] The inspection robot gimbal with lifting function in this utility model can adjust the height of the camera 14 simply by activating the lifting motor 11. The lifting motor 11 drives the threaded rod 10 to rotate, causing the threaded block 12, which is threadedly connected to the threaded rod 10, to rise or fall accordingly. Similarly, adjusting the tilt angle of the camera 14 only requires activating the tilt adjustment motor 13. When the robot is about to enter a low-ceilinged space, to prevent the gimbal from colliding with the ceiling, the lifting motor 11 can be activated first to lower the threaded block 12. After the threaded block 12 reaches its lowest height, the rotating component drives the column 7 to rotate, thus leveling the column 7 and reducing the overall height of the gimbal, making it less likely to collide with the ceiling. Furthermore, the lifting motor 11 and tilt adjustment motor 13 involved in this utility model are existing mature products and will not be described in detail here. The threaded block 12 matches the shape of the internal sliding cavity of the column 7 to prevent the threaded block 12 from failing to rotate independently and thus failing to rise.

[0021] like Figure 3 and Figure 4 As shown, the rotating assembly includes a rotating motor 4, a drive gear 5, and tooth blocks 9. The rotating motor 4 is fixedly connected to the outer wall of the gimbal base 1, the drive gear 5 is fixedly connected to the output end of the rotating motor 4, and multiple tooth blocks 9 are equidistantly distributed on the outer wall of the lower end of the column 7. The tooth blocks 9 mesh with the drive gear 5.

[0022] like Figure 4 As shown, a protective shell 3 is fitted over the rotary motor 4, and the protective shell 3 is fixedly connected to the gimbal base 1. The protective shell 3 can protect the rotary motor 4 and reduce the possibility of damage to the rotary motor 4.

[0023] like Figure 3 and Figure 4 As shown, rotating grooves 8 are provided on both sides of the lower end of the column 7, and rotating rings 6 are fixedly connected to both sides of the upper end of the gimbal base 1. The rotating rings 6 match the rotating grooves 8.

[0024] Specifically, when the column 7 needs to be leveled, simply start the rotary motor 4. The rotary motor 4 will drive the drive gear 5 to rotate. When the drive gear 5 rotates, it will push the tooth block 9 to move. At the same time, since the column 7 is restricted by the rotating ring 6, the column 7 can only rotate, thus allowing the column 7 to rotate to a horizontal state. In addition, since the rotary motor 4 is an existing mature product, it will not be elaborated on here.

[0025] like Figure 1 and Figure 4 As shown, the upper end of the rotating ring 6 has a notch, and the width of the notch is not less than the width of the threaded block 12.

[0026] Specifically, the upper end of the rotating ring 6 has a notch to facilitate the threaded block 12 to enter the center position of the rotating ring 6, so that the threaded block 12 will not collide with the gimbal base 1 when the column 7 rotates.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, fixing blocks 2 are fixed to both sides of the lower end of the gimbal base 1, and positioning blocks 15 are fixed to the top of the gimbal base 1.

[0028] Specifically, the gimbal base 1 is connected and fixed to the inspection robot through the fixing block 2. At the same time, the positioning block 15 restricts the column 7 to prevent the column 7 from rotating too much, which would cause the toothed block 9 fixed on the column 7 to detach from the drive gear 5.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
