Technical Field
[0001] The utility model belongs to the technical field of pipeline cleaning robots, and in particular relates to a mechanical arm cleaning disc. Background Art
[0002] At present, the demand for pipeline cleaning robots is showing a rapid growth trend. With the development of urbanization, various pipeline facilities need to be cleaned and maintained regularly to ensure their normal operation and extend their service life. The traditional manual cleaning method is inefficient and there is a risk of worker injury. Therefore, the demand for efficient and safe pipeline cleaning robots is gradually increasing. The pipe cleaning robot is equipped with a robotic arm, which drives the cleaning disc to clean the pipe. The motor drives the cleaning disc to rotate and clean. The cleaning disc is composed of a base, connecting parts and bristles. In actual work, since the inner wall of the pipe is an arc, the base of the cleaning disc is easy to contact the inner wall of the pipe, which is easy to cause wear and loss, especially when the cleaning disc base rotates, it produces friction with the inner wall of the pipe, which accelerates the loss and easily increases the drive loss of the motor to the cleaning disc, which easily causes the motor to burn out. At the same time, when the cleaning disc cleans the inner wall of the pipe, the rotation and swing of the cleaning disc makes the cleaned dirt easily fall onto the robotic arm and the robot. The dirt may enter the moving parts of the robot, such as joints, wheels or transmission devices, causing jamming, wear and even failure, affecting the normal movement and operation of the robot, and the dirt attached to the robot may fall back into the pipe again, resulting in repeated cleaning, reducing the overall cleaning efficiency.

[0018] In this embodiment: the robot arm 1 supports and drives each component of the device, the driving block 11 supports the cleaning disk base 12, the motor inside the driving block 11 drives the cleaning disk base 12 to rotate, and the cleaning disk base 12 drives the brush 13 to rotate, so that the brush 13 can clean the inner wall of the pipeline, the driving block 11 supports the connecting ring 2 and the four U-shaped connecting frames 3, and the four U-shaped connecting frames 3 limit the connecting ring 2 to prevent the connecting ring 2 from detaching from the driving block 11, the connecting ring 2 supports the protective cover 21, the size of the protective cover 21 is larger than the cleaning disk base 12 and the brush 13, the protective cover 21 shields and protects the outside of the cleaning disk base 12, and the four reset springs 31 push the connecting ring 2 so that the connecting ring 2 can drive the protective cover 21 to slide away from the robot arm 1. When the cleaning disk base 12 and the brush 13 are in use, the protective cover 21 is outside the cleaning disk base 12 and the brush 13, and the protective cover 21 contacts the inner wall of the pipeline. 13 approaches the inner wall of the pipeline, so that the protective cover 21 can be pushed by the reaction force of the pipeline wall to four return springs 31, so that the protective cover 21 can slide toward the direction of the robot arm 1, so that the brush 13 can contact the pipeline wall for cleaning. When the brush 13 is away from the pipeline wall, the return spring 31 pushes the connecting ring 2, and the connecting ring 2 drives the protective cover 21 to return automatically, so that the protective cover 21 can continue to provide external protection for the cleaning disk base 12 and the brush 13, prevent the cleaning disk base 12 from contacting the pipeline wall, reduce the friction loss and friction resistance of the cleaning disk base 12, and prevent the increase of the driving loss of the cleaning disk by the motor, causing the motor to burn out.

The inner walls of the ball covers 22 are rotatably connected with spherical rolling bodies 221; the protective cover 21 supports the ball covers 22, and the ball covers 22 support the corresponding spherical rolling bodies 221. The protective cover 21 contacts the pipe wall through the spherical rolling bodies 221, which facilitates the cleaning work of the brush 13 during the movement and reduces the sliding friction between the protective cover 21 and the pipe wall.
[0020] An annular groove 23 is provided on the connecting ring 2, and the protective cover 21 is rotatably connected to the inner wall of the annular groove 23. The inner wall of the protective cover 21 is rotatably connected to a plurality of cylindrical rolling bodies 24, and the plurality of cylindrical rolling bodies 24 are all slidably connected to the inner wall of the cylindrical rolling bodies 24; the annular groove 23 limits the protective cover 21 to prevent the protective cover 21 from being separated from the connecting ring 2, and the plurality of cylindrical rolling bodies 24 are between the protective cover 21 and the annular groove 23, thereby reducing the friction resistance between the protective cover 21 and the annular groove 23 and facilitating the rotation of the protective cover 21.

At the same time, the guide slide bar 32 guides the connecting ring 2 for sliding to prevent the connecting ring 2 from tilting and deviating when sliding, thereby improving the stability of the connecting ring 2 and the protective cover 21 when in use.
[0023] The working principle and use process of the utility model are as follows: when cleaning the pipe wall, the motor inside the driving block 11 drives the cleaning disc base 12 to rotate, and the cleaning disc base 12 drives the brush 13 to rotate, and the brush 13 rotates to clean the pipe wall, and the protective cover 21 contacts the pipe wall through the spherical rolling body 221, and the cleaning disc base 12 and the brush 13 are driven to approach the inner wall of the pipe by controlling the mechanical arm 1, so that the protective cover 21 can be pushed by the reaction force of the pipe wall to push the four reset springs 31, so that the protective cover 21 can slide toward the direction of the mechanical arm 1, so that the brush 13 can contact the pipe wall for cleaning. The cleaning disk base 12 is shielded by the protective cover 21 and will not contact the pipe wall, reducing the friction loss and increased friction resistance of the cleaning disk base 12, and preventing the increase in the driving loss of the motor on the cleaning disk, which may cause the motor to burn out.
