[0034] Reference Figures 1-3 The first embodiment of the utility model proposes a hanging rail type inspection robot track cleaning device for cleaning the track, the side of the track has an inner concave surface 001, which comprises a body 1, the body 1 is used for sliding on the track, the sliding direction is along the length direction of the track; The swing frame 2 is swingly arranged on the body 1; The brush piece 3 is rotatably arranged on the swing frame 2, and the brush piece 3 is configured, after the body 1 drives the brush piece 3, the brush piece 3 is used for rolling friction abutment with the inner concave surface 001.

[0035] The embodiment mainly consists of a body 1, a swing frame 2 and a brush 3. The track is an I-shaped track, and the body 1 is designed to be slidably installed on the I-shaped track along the length direction of the track. The swing frame 2 is swingably connected to the body 1 through a pivot. The brush 3 is rotatably installed on the swing frame 2 through a rotating shaft. When the track needs to be cleaned, the body 1 slides along the length direction of the track. Due to the swing frame 2, the brush 3 can be self-adapted to the shape and position of the inner concave surface 001 of the track. Under the drive of the body 1, the brush 3 keeps rolling frictional abutment with the inner concave surface 001 of the track, thereby effectively cleaning the contaminants such as dust, debris and oil stains on the inner concave surface 001. The rolling frictional abutment of the brush 3 with the inner concave surface 001 can fully contact each part of the inner concave surface 001 of the track, thereby realizing efficient cleaning and ensuring the cleanliness of the track. The design of the swing frame 2 enables the brush 3 to adapt to the shape and unevenness of the inner concave surface 001 of the track, thereby ensuring the stability of the cleaning effect. In addition, the rolling and frictional mode is relatively gentle, which reduces the damage to the surface of the track and prolongs the service life of the track and the cleaning device. The automatic cleaning device replaces the traditional manual cleaning, thereby greatly reducing the labor intensity and maintenance cost.

[0036] Further, a transmission wheel 4 is rotatably arranged on the swing frame 2, and the transmission wheel 4 is coaxially arranged with the brush 3. The transmission wheel 4 is used to rollingly abut with the track.

[0037] In the embodiment, when the cleaning work is performed, the body 1 moves along the length direction of the track. Due to the flexibility of the swing frame 2, the brush 3 can adapt to the shape and position of the inner concave surface 001 of the track. At this time, the transmission wheel 4 rolls with the track and rotates under the friction of the track. Because the transmission wheel 4 is coaxial with the brush 3, the rotation of the transmission wheel 4 directly provides power for the rotation of the brush 3, so that the brush 3 can continuously and effectively roll frictionally abut with the inner concave surface 001 of the track, thereby removing the contaminants such as dust, debris and oil stains. The arrangement of the transmission wheel 4 ensures that the brush 3 can stably rotate and is not disturbed by external factors, and always maintains good cleaning effect. The power generated by the contact between the track and the transmission wheel 4 eliminates the need for additional energy input, thereby improving the energy utilization efficiency. On the other hand, the rotation speed of the brush 3 can be automatically adjusted according to the moving speed of the body 1 and the track condition, thereby adapting to different cleaning requirements. The need for a complex power system is reduced, thereby reducing the manufacturing and maintenance cost of the device. The simple power transmission structure improves the operation reliability of the device and reduces the possibility of failure.

[0038] Further, the transmission wheel 4 and the brush 3 are both two, which are arranged in pairs on the swing frame 2. The two transmission wheels 4 and the two brushes 3 are respectively located on both sides of the rotating shaft of the swing frame 2, and the two brushes 3 are used to roll frictionally abut with the inner concave surfaces 001 on both sides of the track.

[0039] In this embodiment, the sliding direction of the machine body 1 is the length direction of the track. The swing frame 2 is connected to the machine body 1 through a pivot. Two transmission wheels 4 and two brush pieces 3 are installed on the swing frame 2 in pairs, and the two transmission wheels 4 and the two brush pieces 3 are located on both sides of the rotation axis of the swing frame 2. Since the two brush pieces 3 respectively roll and rub against the inner concave surface 001 on both sides of the track, the track on both sides can be cleaned at the same time. At the same time, the transmission wheels 4 arranged in pairs are in rolling contact with the track, providing power for the rotation of the corresponding brush pieces 3. The arrangement of the two brush pieces 3 working simultaneously can clean the track on both sides at the same time, improving the cleaning efficiency and completing the cleaning work of both sides of the track at one time. The transmission wheels 4 and the brush pieces 3 are arranged in pairs on both sides of the rotation axis of the swing frame 2, so that the swing frame 2 is more balanced in the working process, ensuring the stability of the operation of the cleaning device. At the same time, it also ensures that the inner concave surface 001 on both sides of the track can be fully cleaned without any missed areas, improving the cleaning quality of the track. Also, according to different widths of the track, the swing frame 2 can be adjusted so that both brush pieces 3 can effectively contact the inner concave surface 001 of the track, enhancing the versatility of the device. Further increasing the contact area and cleaning intensity with the track, further improving the removal effect of dust, debris and oil stains and other pollutants.

[0040] Further, the first elastic member 5 is arranged on the machine body 1 at one end and on the swing frame 2 at the other end, and the arrangement point of the first elastic member 5 on the swing frame 2 is located on one side of the swing axis of the swing frame 2, and the first elastic member 5 provides the force for the swing of the swing frame 2.

When the cleaning device is working, the machine body 1 moves along the track. When encountering unevenness or height changes of the inner concave surface 001 of the track, the first elastic member 5 will stretch or contract according to the force, providing the force for the swing of the swing frame 2, so that the swing frame 2 can automatically adjust the angle, so that the brush piece 3 can always roll and rub against the inner concave surface 001 of the track, achieving effective cleaning. The arrangement of the first elastic member 5 enables the swing frame 2 to automatically adapt to the unevenness of the track, ensuring that the brush piece 3 maintains good contact with the inner concave surface 001 of the track, improving the cleaning effect. Reducing the damage to the swing frame 2 and the brush piece 3 caused by sudden impact or excessive pressure, prolonging the service life of the components. At the same time, it ensures that the brush piece 3 applies a relatively stable cleaning pressure to the inner concave surface 001 of the track, avoiding excessive or insufficient pressure that affects the cleaning quality. It can also adapt to different surface conditions of the track, improving the reliability and practicality of the cleaning device under various working conditions.

[0043] In this embodiment, the brush part 3 has a plurality of bristle parts 301, which are arranged in a circular truncated cone type array, specifically, a cylindrical distribution with different diameters of the circular end faces at both ends. The track inner concave surface 001 includes a side flat surface part 002 and an inclined surface part 003 arranged adjacent to each other. During cleaning work, the machine body 1 moves along the track. The brush part 3 adjusts its position with the movement of the swing frame 2. Due to the circular truncated cone type array of the bristle parts 301, the bristle parts 301 on the circular truncated cone type inclined surface can roll and frictionally abut the inclined surface part 003 of the inner concave surface 001, and the bristle parts 301 on the outer cylindrical surface of the circular truncated cone type can roll and frictionally abut the side flat surface part 002 of the inner concave surface 001. This design enables the brush part 3 to fully and closely fit different parts of the inner concave surface 001, effectively removing dust, debris, oil stains and other pollutants. The special arrangement of the bristle parts 301 enables them to fully contact the side flat surface part 002 and the inclined surface part 003 of the inner concave surface 001, achieving omnidirectional cleaning of the track inner concave surface 001 without any cleaning dead angles. The circular truncated cone type array of the bristle parts 301 better adapts to the shape of the inner concave surface 001, increasing the fit of the bristles to the track surface and improving cleaning efficiency and quality. The design of the bristle parts 301 for different parts enables appropriate cleaning force to be applied according to the characteristics of the side flat surface part 002 and the inclined surface part 003, more effectively removing pollutants.
