Description
Technical Field
[0001] The present invention belongs to the field of robots, and particularly relates to a cleaning and spraying robot system. Background Art
[0002] A tunnel lining jumbo is a special equipment that must be used in the secondary lining during the tunnel construction process for the concrete lining construction of the tunnel inner wall. During the operation of the tunnel lining jumbo, formwork erection, pouring, and stripping are constantly required, and this process is always carried out in the narrow space of the tunnel. After each stripping of the formwork, it is necessary to clean and remove scale from the surface of the curved surface structure of the formwork and spray a release agent for maintenance. However, this maintenance process is usually carried out manually, which not only has low efficiency but also poses a great safety hazard.
[0003] The patent document with the application number "CN2020223175783" discloses a cleaning and demoulding agent coating device for a secondary lining stripping jumbo. Arc-shaped slide rails are arranged at both ends of the jumbo. A traveling trolley is arranged at the upper end of the arc-shaped slide rail. A driving mechanism for controlling its movement is arranged at one end of the traveling trolley. A brush rod, a coating rod, and a cleaning rod are successively arranged from top to bottom between the two traveling trolleys. The brush rod, the coating rod, and the cleaning rod are always in contact with the outer surface of the jumbo formwork during the movement process. The inside of the coating rod is a hollow structure, and small holes are evenly arranged on the outer side surface of the coating rod along its length direction for coating the release agent on the outer surface of the jumbo formwork through the small holes. The outer side surface of the brush rod is covered with cotton cloth. Although the device in this comparative document can replace manual labor to clean the outer surface of the jumbo formwork and apply the release agent, it is a special-purpose device and cannot be used universally among different jumbos, and its flexibility in use is poor; moreover, the middle part of the structural member is poorly stressed, and it cannot achieve effective cleaning, nor can it monitor the situation after cleaning, which is likely to cause incomplete cleaning and spraying.
[0004] The patent document with the application number "CN2024209472261" discloses a simple robot for rust removal on the curved surface of a ship hull with a magnetic adsorption track, and the patent document with the application number "CN2018205970402" discloses a tracked wall-climbing robot that can adapt to multiple curved surfaces. The crawler robots in the above two comparative documents both have a certain degree of passability on curved surfaces and are equipped with a magnetic adsorption function, which can be used for spraying and cleaning. However, the angle between the axles of the front and rear wheels of the crawler structure of the robots in the two comparative documents is fixed. When the robot turns or makes a U-turn on a curved surface, one end will tilt up, resulting in a decrease in the degree of fit with the curved surface. When the tangent of the curved surface forms an acute angle with the horizontal plane, it is prone to separate the crawler from the crawling surface under the influence of gravity, posing a risk of falling; moreover, the pipeline is prone to interference with the crawler during walking and is involved in the crawler, affecting the operation.

[0017] Compared with the existing technology, the present invention has the following beneficial effects:
[0018] 1. The cleaning and spraying robot system in the present invention can be adsorbed on the outer side of the trolley formwork through the traveling device. The first frame and the second frame are rotatably connected, and the first wheel frame and the second wheel frame are also rotatably installed on both sides of the first frame and the second frame. When turning or making a U-turn on a curved surface, the whole body can be in a slightly twisted state so that the crawler belt can be fully attached to the curved surface, and the first nozzle connected to the high-pressure water pump assembly can be carried by the swing arm for impurity removal, and the second nozzle connected to the spraying assembly can be used for demoulding agent spraying. It can not only perform large-scale operations but also local operations. The fuselage is thin and flexible, and can completely replace manual labor to perform safe and efficient maintenance operations in a narrow space.
[0019] 2. The suspension assembly in the present invention is provided with a clamping seat with a clamping groove, and a ridge matching the clamping groove is arranged on the inner side of the crawler belt. The suspension assembly can not only provide a certain elastic supporting force for the lower belt surface of the crawler belt but also lift the lower belt surface of the crawler belt upward, so as to form a concave arc structure, enabling it to completely cover the outer side of the formwork when walking on the outer side of the formwork, thereby further improving the fitting degree. When the tangent of the curved surface forms an acute angle with the horizontal plane, even if the body is affected by gravity, the belt wheels at both ends of the crawler belt will not easily separate from the crawling surface, having higher safety.
[0020] 3. The controller in the present invention is installed in the protective box, which can play a protective role. And a supporting wheel is arranged on the second frame, and the supporting wheel is in rolling contact with the outer side of the protective box. This supporting wheel can not only keep the rotation planes of the first frame and the second frame parallel when the first frame and the second frame rotate relative to each other, protect the rotating shaft and the shaft seat from torsion during rotation, and make the rotation posture more stable, but also absorb the axial pressure when the crawler belt is tensioned, playing a protective role for the rotating shaft, bearing and shaft cover.
[0021] 4. The periphery of the traveling device in the present invention is provided with a first pipe clamp and a second pipe clamp to clamp the first pipeline and the second pipeline, so that the pipeline and the circuit can be arranged around the periphery of the traveling device and have a certain gap. When the vehicle body of the traveling device generates torsion, a certain movement gap can be allowed between the pipeline and the pipe clamp, which neither affects the movement posture nor pulls the pipeline, and can avoid the position of the crawler belt to avoid interference.
[0022] 5. The periphery of the traveling device in the present invention is provided with a camera, a lighting lamp and a position sensor, which can remotely observe the operation situation and automatically identify the operation boundary, having good visibility and active safety protection, making the operation more convenient; a rope rack for fixing the safety rope is also arranged on the second frame, which can further play a safety protection role during the operation.
[0023] 6. The drive wheels at both ends of the crawler in the present invention are driven by independent drive motors, which endows it with high power performance and enables uniform distribution of power in both the front and rear directions. When moving backward or passing through obstacles, it has strong passability and power output. BRIEF DESCRIPTION OF THE DRAWINGS

The other end of the swing arm 700 extends outward from the other end of the first vehicle frame 400 and can swing between the two sides of the traveling device 100 to form a fan-shaped sweeping area. A first spray head 720 and a second spray head 730 are installed at the other end of the swing arm 700. The spray holes of the first spray head 720 are linear spray holes and their extension lines pass through the rotation center of the swing arm 700.

The swing lengths of the elastic arms 810 gradually increase from the center position to the two end positions, so as to be able to lift the lower belt surface of the crawler belt 600 upward and make the lower belt surface of the crawler belt 600 form a concave arc structure, so as to form a better fit with the convex curved surface of the template.
[0053] In addition, a camera 120, two lighting lamps 130 and two position sensors 140 are respectively installed at both ends of the traveling device 100.

A safety rope is fixed above the formwork, and the end of the safety rope is tied to the rope rack 150. Images are transmitted to the control end through the camera 120 and the lighting lamp 130. The swing of the swing arm 700 on the left and right sides of the traveling device 100 drives the first nozzle 720 to spray a fan-shaped cleaning area of high-pressure water flow in a linear shape, so as to clean the residues and foreign matters on the outer surface of the formwork; after cleaning, the swing arm 700 drives the second nozzle 730 to spray the release agent on the formwork surface in the end area of the traveling device 100, and at the same time, the third nozzles 740 located on both sides of the traveling device 100 can spray the release agent on the formwork surface in the side area of the traveling device 100, so as to form a larger spraying area and ensure the spraying efficiency during the spraying of the release agent.
[0056] Since the surface of the template is a convex curved surface structure, when the traveling device 100 crawls along the arc direction, due to the engagement and slidability between the clamping seat 830 at the end of the elastic arm 810 in the suspension assembly 800 and the ridge 630 on the back side of the crawler belt 600, the lower belt surface of the crawler belt 600 is lifted upward to form a concave arc structure, which fits perfectly with the outer side surface of the template; when the traveling device 100 crawls along the arc direction perpendicular to the template, the first wheel frame 410 and the second wheel frame 510 can automatically deflect inward according to the curvature of the arc surface, so as to achieve a high degree of fit; when the traveling device 100 makes a turning or U-turn movement on the outer side surface of the template, adaptive rotation can occur between the four wheel frames and between the first vehicle frame 400 and the second vehicle frame 500, so that the crawler belt 600 has a better fit with the curved surface. When encountering slight protrusion-like dirt obstacles on the curved surface, the crawler belt 600 can also have better passability. When the traveling device 100 travels to an angle where the tangent of the curved surface forms an acute angle with the horizontal direction, since the lower belt surface of the crawler belt 600 always maintains a concave arc structure, the movement tendency of the first drive wheel 430 and the second drive wheel 530 to lift off the curved surface can also be eliminated, and the separation and fall of the crawler belt 600 and the curved surface can be better prevented.
[0057] In summary, the cleaning and spraying robot system in the present invention can be adsorbed on the outer side of the trolley template through the traveling device 100. The first vehicle frame 400 and the second vehicle frame 500 are rotatably connected, and the first wheel frame 410 and the second wheel frame 510 are also installed on both sides of the first vehicle frame 400 and the second vehicle frame 500 in a rotatable manner. When making a turn or U-turn on the curved surface, the whole body of the vehicle can be in a slightly twisted state so that the crawler belt 600 fits perfectly with the curved surface, and the first spray head 720 connected to the high-pressure water pump assembly 200 can be carried by the swing arm 700 to remove impurities, and the second spray head 730 connected to the spraying assembly 300 can spray the release agent. It can not only perform large-scale operations but also perform local operations. The fuselage is thin and the movement is flexible, and it can completely replace manual labor to perform safe and efficient maintenance operations in a narrow space.
