Description

Technical Field

[0001] This utility model relates to cleaning devices for road traffic facilities, and more particularly to an automatic cleaning device for highway tunnels. Background Technology

[0002] In the maintenance system of road traffic facilities, tunnels are a key component, and their cleanliness directly affects driving safety and the travel experience. With the continuous expansion of the highway network and the increasing traffic flow, the demand for efficient and intelligent highway tunnel cleaning equipment is becoming increasingly urgent.

[0003] Currently, the conventional method for cleaning highway tunnels is regular manual cleaning. During manual cleaning, cleaning personnel must wear protective clothing and carry simple tools such as brooms and cleaning agents to enter the tunnel. However, this method has many drawbacks, resulting in high cleaning costs in the long run. Therefore, there is a significant lack of rapid and timely on-site cleaning solutions in existing technologies.

[0004] Furthermore, manual cleaning is time-consuming and labor-intensive. The interior of tunnels is relatively enclosed and complex, with problems such as poor ventilation and dim lighting. Cleaning personnel working in such environments for extended periods are prone to fatigue, significantly reducing their work efficiency. Moreover, manual cleaning cannot be performed frequently enough, meaning that dirt, dust, and oil stains on tunnel walls and surfaces cannot be removed promptly. Over time, this not only affects the tunnel's aesthetics but may also reduce lighting effectiveness and increase the risk of traffic accidents.

[0005] Therefore, it is urgent to develop an efficient, intelligent, and rapidly responsive automatic cleaning device for highway tunnels. Utility Model Content

[0006] In view of the above-mentioned prior art, this utility model provides an automatic cleaning device that can be implemented on-site in highway tunnels, which can clean relevant facilities (including lighting equipment, ventilation equipment, signs, etc.) in highway tunnels in a timely, fast and automatic manner.

[0007] To address the aforementioned technical problems, this utility model proposes an automatic cleaning device for highway tunnels, comprising a robot walking track, a support mechanism, a robot body, and a cleaning device. A robot quick-change device is connected between the cleaning device and the execution end of the robot body. The robot quick-change device includes a main plate fixed to the robot body and a tool plate fixed to the cleaning device. The main plate includes a main plate electrical signal connection unit, and the tool plate includes a tool plate electrical signal connection unit. The tool plate electrical signal connection unit and the main plate electrical signal connection unit are connected after the main plate and the tool plate are connected. The cleaning device includes a rotating brush and a mounting flange. The rotating brush is equipped with a drive device. The mounting flange includes two L-shaped flange seats, one of which is connected to the tool plate, and the drive device is mounted on the other flange seat. The output shaft of the drive device is connected to the rotation shaft of the rotating brush. A drive device control line is connected between the tool plate electrical signal connection unit and the drive device to supply power to the drive device, thereby providing power to the rotating brush.

[0008] Furthermore, in the automatic cleaning device described in this utility model:

[0009] The supporting mechanism includes a mounting base plate, on which four sets of bearing seats are provided. The four sets of bearing seats are arranged coaxially in pairs. Each bearing seat is provided with a load-bearing shaft, and each load-bearing shaft is provided with a load-bearing roller. The load-bearing roller cooperates with the robot's walking track. The fixed end of the robot body is connected to the bottom of the mounting base plate, and the main plate of the robot quick-change device is installed on the execution end of the robot body.

[0010] The main plate of the robot quick-change device and the tool plate of the robot quick-change device are connected or disconnected through a piston-type steel ball locking structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The cleaning device is mounted on the robot using a quick-change structure. The carrying mechanism drives the cleaning device to the designated position along the robot's walking track. The drive device drives the rotating brush to achieve rapid and automatic cleaning of the relevant equipment in the tunnel. Attached Figure Description

[0043] like Figure 1 and Figure 2As shown, this utility model proposes an automatic cleaning device for highway tunnels, including a robot walking track 1, a supporting mechanism 2, a robot body 3, and a cleaning device 7. A robot quick-change device is connected between the cleaning device 7 and the execution end of the robot body 3. The robot quick-change device includes a main plate 4 fixed to the robot body 3 and a tool plate 6 fixed to the cleaning device 7. The main plate 4 includes a main plate electrical signal connection unit 45, and the tool plate 6 includes a tool plate electrical signal connection unit 63. The tool plate electrical signal connection unit 63 and the main plate electrical signal connection unit 45 are connected after the main plate 4 and the tool plate 6 are connected. Figure 3 As shown, the cleaning device 7 includes a rotating brush 73 and a mounting flange 71. The rotating brush 73 is equipped with a drive device 72. The mounting flange 71 includes two flange seats that are L-shaped to each other. One flange seat is connected to the tool tray 6 of the robot quick-change device. The drive device 72 is mounted on the other flange seat. The output shaft of the drive device 72 is connected to the rotation shaft of the rotating brush 73. The tool tray electrical signal connection unit 63 is connected to the drive device 72 by a drive device control line 74, which supplies power to the drive device 72, thereby providing power to the rotating brush 73.

[0044] like Figure 4 As shown, the supporting mechanism 2 includes a mounting base plate 21, on which four sets of bearing seats 22 are provided. The four sets of bearing seats 22 are arranged coaxially in pairs. Each bearing seat 22 is provided with a load-bearing shaft 23, and each load-bearing shaft 23 is provided with a load-bearing roller 24. The load-bearing roller 24 cooperates with the robot walking track 1. The fixed end of the robot body 3 is connected to the bottom of the mounting base plate 21. The robot quick-change device main plate 4 is installed at the execution end of the robot body 3 through a connecting flange 46.

[0045] The main plate 4 and the tool plate 6 of the robot quick-change device are connected by a piston-type steel ball locking structure (e.g., Figure 1 ) or break away (such as Figure 2 and Figure 3 ).

[0046] Taking the cleaning of a tunnel lighting system as an example, in specific applications, such as... Figure 1As shown, the robot quick-installation device main plate 4 is fixedly connected to the robot body 3 via its mounting flange. The automatic cleaning device is mounted on the robot body 3, which is equipped with the robot quick-installation device main plate 4, using a piston-type steel ball locking principle. The robot body 3 is mounted on the robot travel track 1 via the support mechanism 2, which is installed on the inner wall of a highway tunnel. After the robot body 3 mounts the cleaning device 7 via the robot quick-change device main plate 4, it drives the rotating brush 73 to clean the lighting system 8.

[0047] The main plate 4 and the tool plate 6 of the robot quick-change device are connected or disconnected via a piston-type steel ball locking structure. In this utility model, as... Figures 5 to 8 As shown, the piston-type steel ball locking structure is as follows:

[0048] The robot quick-change device's main disk 4 is equipped with an axial cylinder 53. A piston rod sleeve 49 is fixed to the bottom of the axial cylinder 53. A main disk piston 47 is located inside the axial cylinder 53. The piston rod 50 of the main disk piston 47 passes through the piston rod sleeve 49. Multiple circumferentially distributed main disk locking steel balls 48 are installed on the lower cylinder wall of the piston rod sleeve 49 through mounting holes. A steel ball push rod 51 is fixed to the bottom of the piston rod 50. The outer edge of the bottom end of the steel ball push rod 51 is provided with an outer conical surface 52. The main disk piston 47 divides the axial cylinder 53 into an upper air chamber 55 and a lower air chamber 54. The axial cylinder 53 is provided with a first air passage 43 leading to the upper air chamber 55 and a second air passage 44 leading to the lower air chamber 54. The robot quick-change device tool disc 6 is provided with a tool disc assembly hole 67, and a tool disc locking ring 65 is fixed in the tool disc assembly hole 67. The lower end of the tool disc locking ring 65 is provided with an inner conical surface 68. The inner diameter of the tool disc locking ring 65 matches the outer diameter of the piston rod sleeve 49.

[0049] When the main disc piston 47 is at its highest position, the main disc locking ball 48 contacts the outer conical surface 52 of the ball push rod 51. At this time, the main disc 4 of the robot quick-change device disengages from the tool disc 6 of the robot quick-change device. Figure 2 , Figure 3 and Figure 7 As shown.

[0050] When the main disc piston 47 is in its lowest position, the main disc locking ball 48 contacts the inner conical surface 68 of the tool disc locking ring 65 and is located outside the ball push rod 51. At this time, the main disc 4 of the robot quick-change device is connected to the tool disc 6 of the robot quick-change device. Figure 1 and Figure 8 As shown. Figure 8The diagram shows the locked state of the main disk 4 and tool disk 6 of the robot quick-change device, where: Figure 8 (a) is the front view; Figure 8 (b) is the top view; Figure 8 (c) is Figure 8 (b) shows the connection status of the robot quick-change device main disk 4 and the robot quick-change device tool disk 6 in the BB section view. Figure 8 (d) is Figure 8 (b) CC cross-sectional view shows a schematic diagram of compressed air being delivered from the main plate 4 of the robot quick change device through the second air pipe connection port 42 of the main plate to the second air pipe connection port 62 of the tool plate of the robot quick change device. Figure 8 (e) is Figure 8 (b) is a cross-sectional view of DD, showing a schematic diagram of the power supply of the drive unit 72 being transmitted to the robot quick-change device tool disk 6 through the robot quick-change device main disk; Figure 8 (f) is Figure 8 (b) is a cross-sectional view of EE, showing a schematic diagram of gas entering the upper air chamber 55 above the piston from the first air passage 43, driving the main disk piston 47 to move downward. Figure 8 (g) is Figure 8 (b) is a cross-sectional view of FF, showing a schematic diagram of gas entering the lower chamber 54 of the piston from the second gas passage 44 and driving the main disk piston 47 to move upward; Figure 8 (h) is Figure 8 (b) is a cross-sectional view of GG, showing a schematic diagram of compressed air being delivered from the main plate 4 of the robot quick-change device to the tool plate 6 of the robot quick-change device through the first air pipe connection port 41.

[0051] Hollow sealing plugs 66 are respectively provided between the first air pipe connection port 61 of the tool disc and the first air pipe connection port 41 of the main disc, and between the second air pipe connection port 62 of the tool disc and the second air pipe connection port 42 of the main disc, to prevent gas leakage. Therefore, the rotary brush drive device 72 can also be driven by a pneumatic motor driven by compressed air.

[0052] When the robot body 3 and the robot quick-change device main plate 4 fixed thereon reach the mounting position of the robot quick-change device tool plate 6 along the robot walking track 1 under the drive of the bearing mechanism 2, the robot quick-change device main plate 4, with gas introduced into the upper air chamber 55 through the first air passage 43, pushes the main plate piston 47 downward. The steel ball push rod 51 fixed to the bottom of the piston rod 50 pushes out the main plate locking steel ball 48, thereby locking the tool plate locking ring 65, thus connecting the robot quick-change device main plate 4 and the robot quick-change device tool plate 6 together, realizing the mounting of the robot body 3 and the cleaning device 7. Figure 1 and Figure 8 As shown.

[0053] When the robot body 3 is unloaded from the cleaning device 7, the main plate 4 of the robot quick-change device, through the second air passage 44, introduces gas into the lower air chamber 54, pushing the main plate piston 47 upward. The main plate locking ball 48 resets and retracts into the tool plate locking ring 65, unlocking the tool plate locking ring 65, thus separating the robot body 3 from the cleaning device 7. Figure 2 , Figure 3 and Figure 7 .

[0054] The lighting system 8 described in this utility model can be an LED array.

[0055] In this embodiment, the drive unit 72 is connected to the rotating shaft of the rotating brush 73 via the drive unit mounting flange 71, and the drive unit 72 is also connected to the robot quick-change device tool disk 6 via the drive unit mounting flange 71. The drive unit control line 74 is located on the robot quick-change device tool disk 6 and is connected to the tool disk electrical signal connection unit 63.

[0056] When the main plate 4 of the robot quick-change device is mounted on the tool plate 6 of the robot quick-change device, the power supply is connected through the metal contact 64 of the main plate electrical signal connection unit 45 and the metal contact 64 of the tool plate electrical signal connection unit 63. The power is transmitted to the drive device 72 through the drive device switch control line 74, thereby driving the drive device 72 to move. The drive device 72 drives the rotating brush 73 to rotate on the LED array, thereby cleaning the LED array.

[0057] When the highway tunnel lighting system needs cleaning, the robot body 3 on site connects to the robot quick-change device tool disk 6 of the automatic cleaning device via its main robot quick-change device main disk 4, and the automatic cleaning device 7 is automatically mounted. Then, the automatic cleaning device 7 is moved to various distribution points of the lighting system, and the rotating brush 73 is moved to the surface of the lighting system 8 for cleaning by changing the robot's posture.

[0058] The above-mentioned work process can be automatically completed by a robot carrying this automatic cleaning device.

[0059] Although the present invention has been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many improvements and changes under the guidance of the present invention without departing from the spirit of the present invention, and these improvements and changes are all within the protection scope of the present invention.
