[0035] The utility model provides a track cleaning mechanism 1.

[0036] Please combine Figure 1 and Figure 3In the track cleaning mechanism 1 of the present embodiment, the track 10 is provided with a gripper 40 that can move along the track 10, the track 10 is an I-beam track 10, the track 10 includes a top plate 11, a bottom plate 12 and a web 13 connected between the top plate 11 and the bottom plate 12; the track cleaning mechanism 1 includes a frame 20 and two cleaning components 30, the top of the frame 20 is provided with an opening 22, the frame 20 is used to be installed on the gripper 40; the two cleaning components 30 are accommodated in the frame 20 and are respectively located on opposite sides of the opening 22, the cleaning components 30 include a mounting platform 31, a friction wheel 32, a transmission component 33 and a cleaning brush 3 4. The mounting platform 31 is mounted on the frame 20, and the transmission assembly 33 is mounted in the mounting platform 31. The friction wheel 32 drives the cleaning brush 34 to rotate through the transmission assembly 33. A gap is formed between the friction wheels 32 in the two cleaning assemblies 30 for the web 13 to pass through, and the two friction wheels 32 are in rolling contact with the web 13, and the two cleaning brushes 34 are located above the bottom plate 12; when the holding device 40 moves along the track 10, it drives the frame 20 to slide along the track 10, so that the friction wheel 32 and the web 13 rub and roll, and then drives the cleaning brush 34 through the transmission assembly 33 to rotate to clean the bottom plate 12.

[0037] In the technical solution of the utility model, a cleaning assembly 30 is respectively arranged on both sides of the web 13, and the friction wheel 32 rolls with the web 13. When the friction wheel 32 rolls, the cleaning brush 34 is driven to rotate through the transmission assembly 33 to clean the bottom plate 12. During use, when the holding device 40 drives the vehicle body to move, the holding device 40 also drives the frame 20 on its top to move along the track 10. During the movement, since the friction wheel 32 is in direct contact with the web 13 and generates friction rolling, the rolling of the friction wheel 32 is transmitted to the cleaning brush 34 through the transmission assembly 33, thereby driving the cleaning brush 34 to rotate, thereby achieving cleaning of the bottom plate 12. The utility model realizes that no additional power source is required. The bottom plate 12 can be cleaned by the cooperation of the friction wheel 32, the transmission component 33 and the cleaning brush 34. The cleaning component 30 moves with the movement of the holder 40, and can clean the impurities on the bottom plate 12 in real time to prevent the accumulation of impurities on the bottom plate 12, thereby preventing impurities from falling on the vehicle body on the holder 40 during the movement, greatly reducing the slag and foreign matter protrusions on the vehicle body after spraying, improving the surface quality of the vehicle body painting, and at the same time improving the production efficiency.

[0038] Please combine Figure 1 and Figure 2In one embodiment, the transmission assembly 33 includes a first transmission wheel 331 and a second transmission wheel 333. The first transmission wheel 331 is connected to the friction wheel 32 through a first rotating shaft 332, and the second transmission wheel 333 is connected to the cleaning brush 34 through a second rotating shaft 341. The first transmission wheel 331 and the second transmission wheel 333 are meshed. It can be understood that the transmission wheel is a gear, and the rotation of the friction wheel 32 is transmitted through the gear transmission. The transmission efficiency is high and the energy transmission loss is relatively small. Therefore, the input speed and torque of the friction wheel 32 can be effectively transmitted to the cleaning brush 34. At the same time, the gear transmission can also achieve different transmission ratios by adjusting the gear ratio between the two gears, which is more flexible. For this reason, in a preferred embodiment, the number of teeth of the first transmission wheel 331 is greater than the number of teeth of the second transmission wheel 333, so that the friction wheel 32 can more easily drive the cleaning brush 34 to rotate.

[0039] Furthermore, the cleaning brush 34 includes a second rotating shaft 341, a joint 342, and a plurality of bristles 343 for cleaning the bottom plate, wherein the plurality of bristles 343 are arranged at intervals along the circumference of the joint 342, one end of the second rotating shaft 341 is connected to the second transmission wheel 333, and the other end of the second rotating shaft 341 is connected to the joint 342. The plurality of bristles 343 are arranged at intervals along the circumference of the joint 342 to avoid entanglement between the bristles 343 and maintain the functionality of the cleaning brush. At the same time, the deformation ability of a single bristle 343 is stronger and can be adapted to more usage scenarios.

[0040] In one embodiment, the joint 342 is arranged parallel to the bottom plate 12, and the bristles 343 are arranged obliquely to the joint 342, so that the bristles 343 abut against the bottom plate 12. The bristles 343 and the joint 342 are arranged obliquely, which can ensure that the end of the bristles 343 away from the joint 342 is always in contact with the bottom plate 12, thereby avoiding missed brushing and improving cleaning efficiency.

[0041] In one embodiment, one end of the mounting platform 31 away from the web 13 is hinged on the frame 20, and a transmission assembly 33 is provided at one end of the mounting platform 31 close to the web 13. It can be understood that since the track 10 is not a straight line but also includes many curved lines, one end of the mounting platform 31 is hinged to the frame 20. When the friction wheel 32 is subjected to a large force at a curve, the mounting platform 31 will be driven to rotate to adapt to the curve, thereby avoiding damage to the friction wheel 32 and extending its service life.

[0042] Furthermore, an elastic reset member 21 is also installed on the frame 20, one end of the elastic reset member 21 is connected to the frame 20, and the other end is connected to the mounting platform 31. After completing the bend, the elastic reset member 21 is used to pull the mounting platform 31 back to its original position to maximize its cleaning area.

[0043] Specifically, the friction wheel 32 is a rubber wheel. Rubber has good friction properties and can provide a high friction coefficient. Therefore, the rubber friction wheel 32 can provide sufficient friction when contacting the surface of the web 13 to avoid the occurrence of air slip, so as to ensure that the friction wheel 32 can stably drive the cleaning brush to rotate and improve the stability of the cleaning brush.

[0044] In one embodiment, a debris collection box is provided at the edge of the bottom of the frame 20 away from the side of the web 13, and the debris collection box is provided corresponding to the cleaning brush. By providing the debris collection box at the bottom of the web 13, debris and other impurities are further prevented from falling on the surface of the vehicle body, thereby further improving the quality of the vehicle body spraying.

[0045] Furthermore, the frame 20 is provided with a magnetic member near the debris collection box, and the magnetic member is used to absorb iron powder. By arranging the magnetic member to absorb iron powder, the iron powder is prevented from floating in the air and causing safety accidents.

[0046] The utility model also provides a vehicle body transport device, including a track 10, a gripper 40 and the above-mentioned track cleaning mechanism 1, the track 10 is an I-beam track 10, the track 10 includes a top plate 11, a bottom plate 12 and a web 13 connected between the top plate 11 and the bottom plate 12; the gripper 40 includes a transport frame and a driving wheel installed on the top of the transport frame, the driving wheel abuts against the bottom plate 12 and drives the transport frame to move along the track 10, and the transport frame is used to carry the vehicle body; the frame 20 of the track cleaning mechanism 1 is installed above the transport frame. The specific structure of the track cleaning mechanism 1 refers to the above-mentioned embodiment. Since the vehicle body transport device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0047] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
