Abstract
Description
Technical Field
[0001] This utility model relates to the field of inspection robot technology, specifically to an inspection robot camera gimbal mounting structure. Background Technology
[0002] The camera on the inspection robot is one of the core sensors for it to perceive the environment and perform tasks. Its main function is to help the robot "see" the surrounding environment and complete tasks such as information collection, status monitoring and autonomous navigation.
[0003] Inspection robots often operate in dusty (e.g., coal mines, cement plants), humid (e.g., tunnels, underground utility tunnels), or oily (e.g., petrochemical, steel plants) environments. Dust, water stains, or oil films easily accumulate on the lens surface, leading to blurred images (e.g., unreadable instrument readings). Conventional cleaning methods (e.g., air blowing, wiping) can temporarily restore clarity to some extent, but after completing one or more inspection tasks, the camera often needs to be disassembled for deep cleaning, or even replaced. However, the camera pan-tilt unit is usually fixed to the robot body with bolts. This fixing method requires specialized tools for disassembly and assembly during maintenance, making the operation cumbersome, time-consuming, and significantly reducing the equipment's maintenance efficiency. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a camera gimbal mounting structure for inspection robots, which allows for quick assembly and disassembly of the camera gimbal from the robot body without the need for tools.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a camera pan-tilt mounting structure for an inspection robot, comprising a support column located between the robot body and the camera pan-tilt, the upper end of the support column being fixedly connected to the lower end of the camera pan-tilt, a base being fixedly connected to the lower end of the support column, a mounting plate being fixedly connected to the top of the inner wall of the robot body, the base being slidably connected to the mounting plate, and a plurality of limiting components being connected to the top of the robot body, the other ends of the plurality of limiting components being connected to the mounting plate.
[0006] Furthermore, the upper surface of the robot body has several moving ports, and the lower end of each of the moving ports has a spring cavity. The side wall of the upper end of the base has several insertion ports. One end of the limiting component is located in the moving port and the spring cavity, and the other end of the limiting component is located in the insertion port.
[0007] Furthermore, the limiting component includes an L-shaped block and a thrust spring. The two ends of the L-shaped block are located in the moving port and the spring cavity, respectively, and the L-shaped block is slidably connected to both the moving port and the spring cavity. One end of the thrust spring is fixedly connected to the inner wall of the spring cavity, and the other end of the thrust spring is fixedly connected to the end of the L-shaped block located in the spring cavity. The end of the L-shaped block away from the thrust spring is slidably connected to the insertion port.
[0008] Furthermore, a sealing disc is fitted and slidably connected to the outer wall of the support column, with the bottom surface of the sealing disc abutting against the upper surface of the robot body.
[0009] Furthermore, the top surface of the inner wall of the sealing disc is provided with several limiting ports, and one end of several L-shaped blocks passing through the moving port is slidably connected to several limiting ports respectively.
[0010] Furthermore, a sealing ring is fixedly connected to the upper surface of the robot body, and a sealing port is opened on the bottom surface of the sealing disc, with the sealing ring and the sealing port slidably connected.
[0011] Furthermore, the inner walls of both the robot body and the mounting plate are provided with several limiting grooves, and the side walls of the base are fixedly connected with several blocking blocks, which are slidably connected to the limiting grooves.
[0012] Furthermore, passive sockets are fixedly connected to the bottom of both blocks, and active plugs are fixedly connected to both sides of the lower end of the mounting plate, with the two active plugs aligned with the positions of the two passive sockets respectively.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The camera gimbal mounting structure of this inspection robot, through the sliding connection between the base and the mounting plate, and with the limit component composed of L-shaped blocks and thrust springs, allows the camera gimbal to be installed and disassembled without the aid of tools.
[0015] 2. The camera gimbal mounting structure of this inspection robot effectively prevents dust, water stains, oil stains and other pollutants from entering the robot body by setting a sealing plate, sealing ring and sealing port. It solves the problem that traditional structures are prone to short circuits or mechanical jamming due to environmental impurities. It is especially suitable for harsh working conditions such as coal mines, cement plants and petrochemical plants, and significantly extends the service life of the equipment.
[0016] 3. The camera pan-tilt mounting structure of this inspection robot, by setting a passive socket and an active plug, eliminates the need for additional wiring steps, simplifying the installation process, while ensuring a stable circuit connection between the camera pan-tilt and the robot body.

[0025] 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.
[0026] Please see Figures 1-7 A camera pan-tilt mounting structure for an inspection robot includes a support column 4 located between the robot body 1 and the camera pan-tilt 2. The upper end of the support column 4 is fixedly connected to the lower end of the camera pan-tilt 2. A base 5 is fixedly connected to the lower end of the support column 4. A mounting plate 6 is fixedly connected to the top of the inner wall of the robot body 1. The base 5 and the mounting plate 6 are slidably connected. Several limiting components are also connected to the top of the robot body 1. The other ends of the limiting components are all connected to the mounting plate 6.
[0027] like Figures 1 to 7 As shown, when installing the camera gimbal 2 onto the robot body 1, the camera gimbal mounting structure of this utility model only requires aligning the base 5, which is fixed to the camera gimbal 2 by the support column 4, with the mounting plate 6 on the robot body 1, and then inserting the base 5 into the mounting plate 6 to initially limit the camera gimbal 2 and the robot body 1. At the same time as the base 5 is inserted into the mounting plate 6, several limiting components located on the robot body 1 will further limit the base 5 from the side, thereby further improving the stability of the camera gimbal 2 on the robot body 1.
[0028] Furthermore, when it is necessary to remove the camera gimbal 2 from the robot body 1, simply loosen a few limiting components, and then the base 5 can be pulled out from the mounting plate 6, thereby achieving rapid separation of the camera gimbal 2 from the robot body 1. The entire process requires no additional tools and is easy to operate.
[0029] It should be noted that the robot body 1 and the camera gimbal 2 are both mature technologies in existing four-wheeled inspection robots. In this utility model, only the disclosed patent structure is partially improved. Structures not mentioned, such as the power supply and controller, are not modified in any way and retain their original functions and effects. They will not be described in detail here.
[0030] As a preferred embodiment of this utility model, the upper surface of the robot body 1 is provided with a plurality of movable openings 103, and the lower ends of the plurality of movable openings 103 are provided with spring cavities 102. The side wall of the upper end of the base 5 is provided with a plurality of insertion slots 501. One end of the limiting component is located in the movable openings 103 and the spring cavities 102, and the other end of the limiting component is located in the insertion slots 501.
[0031] More specifically, by setting up the movable port 103, the spring cavity 102 and the insertion port 501, the limiting component can be stored, improving its stability. Secondly, the connection stability between the robot body 1 and the camera gimbal 2 can be guaranteed.
[0032] As a preferred embodiment of this utility model, the limiting component includes an L-shaped block 10 and a thrust spring 11. The two ends of the L-shaped block 10 are located in the moving port 103 and the spring cavity 102, respectively, and the L-shaped block 10 is slidably connected to both the moving port 103 and the spring cavity 102. One end of the thrust spring 11 is fixedly connected to the inner wall of the spring cavity 102, and the other end of the thrust spring 11 is fixedly connected to the end of the L-shaped block 10 located in the spring cavity 102. The end of the L-shaped block 10 away from the thrust spring 11 is slidably connected to the insertion port 501.
[0033] More specifically, when it is necessary to connect the camera gimbal 2 to the robot body 1, simply align the base 5 below the camera gimbal 2 with the mounting plate 6 and insert it. When the bottom surface of the base 5 rests on the upper surface of one end of the spring cavity 10 through several L-shaped blocks 10, the base 5 is blocked from descending. However, at this time, part of the base 5 is already inside the mounting plate 6. Without a large external force, the camera gimbal 2 will not collapse or fall.
[0034] Afterwards, the installer only needs to pull the L-shaped block 10 through one end of the movable port 103. The L-shaped block 10 is displaced along the spring cavity 102 under the force, and squeezes the push spring 11 during the displacement, so that the L-shaped block 10 can be pulled back into the spring cavity 102. At this time, the camera gimbal 2 slides down to the bottom of the mounting plate 6 by itself due to gravity (in order to avoid sudden drop and damage to the camera gimbal 2, it can be supported by hand). Then, the L-shaped block 10 is released. At this time, due to the action of the push spring 11, the L-shaped block 10 will be inserted into the socket 501 along the spring cavity 102, thereby completing the connection limit between the robot body 1 and the camera gimbal 2.
[0035] As a preferred embodiment of this utility model, a sealing disc 3 is sleeved and slidably connected to the outer wall of the support column 4, and the bottom surface of the sealing disc 3 abuts against the upper surface of the robot body 1.
[0036] More specifically, by setting up the sealing plate 3, a shield can be provided at the connection between the robot body 1 and the camera gimbal 2, reducing the probability of external debris falling into it.
[0037] As a preferred embodiment of this utility model, the top surface of the inner wall of the sealing disc 3 is provided with several limiting ports 302, and one end of several L-shaped blocks 10 passing through the moving port 103 is slidably connected to several limiting ports 302 respectively.
[0038] More specifically, by setting the limiting port 302, the end of the L-shaped block 10 that extends through the moving port 103 can be limited by the limiting port 302, ensuring that the L-shaped block 10 cannot move while the sealing plate 3 is not lifted, thereby ensuring the effective connection between the robot body 1 and the camera gimbal 2.
[0039] It is important to note that in practical applications, when the sealing disc 3 moves down along the support column 4, the sliding groove can be used to restrict the sealing disc 3 to move vertically and not rotate. This ensures that the limiting port 302 and the L-shaped block 10 are aligned. Of course, this can also be omitted. Although the limiting port 302 and the L-shaped block 10 may not be perfectly aligned, this can still be used to determine whether the sealing disc 3 has descended to the bottom (because if the two are not aligned, the sealing disc 3 will not reach the bottom).
[0040] As a preferred embodiment of this utility model, a sealing ring 8 is fixedly connected to the upper surface of the robot body 1, and a sealing port 301 is opened on the bottom surface of the sealing disk 3. The sealing ring 8 is slidably connected to the sealing port 301.
[0041] More specifically, by setting the sealing ring 8 and the sealing port 301, the sealing effect at the connection between the robot body 1 and the camera gimbal 2 can be further improved, and there is a large friction between the sealing ring 8 and the sealing port 301, which reduces the probability of the sealing plate 3 becoming loose.
[0042] As a preferred embodiment of this utility model, the inner walls of both the robot body 1 and the mounting plate 6 are provided with a plurality of limiting grooves 101, and the side wall of the base 5 is fixedly connected with a plurality of blocking blocks 9, which are slidably connected to the limiting grooves 101.
[0043] More specifically, by setting the limiting groove 101 and the blocking block 9, it can be ensured that the orientation of the insertion port 501 is aligned with the orientation of the spring cavity 102 during the process of inserting the base 5 into the mounting plate 6.
[0044] In a preferred embodiment of this utility model, the bottom of each of the two blocking blocks 9 is fixedly connected to a passive socket 12, and the two sides of the lower end of the mounting plate 6 are fixedly connected to active plugs 7, with the two active plugs 7 aligned with the positions of the two passive sockets 12 respectively.
[0045] More specifically, by setting the active plug 7 and the passive socket 12 as two sets, the power supply and controller inside the robot body 1 can be connected to the camera gimbal 2 and the robot body 1 respectively. Thus, after the base 5 is inserted into the mounting plate 6, the camera gimbal 2 can be powered on and controlled by the controller inside the robot body 1 (e.g., turning, raising, etc.).
[0046] 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.
