Description

Technical Field

[0001] This application relates to the field of wall cleaning technology, and in particular to a rust removal and cleaning device and a wall-climbing robot. Background Technology

[0002] In recent years, with the shipbuilding, wind power, and petrochemical industries in my country entering a new stage of development and the booming development of the high-tech robotics industry, more and more companies are turning their attention to applying robots to the daily maintenance of these industries. By replacing manual labor with robots, they aim to reduce labor costs and improve issues such as low work efficiency, inconsistent work quality, and safety hazards. Rust removal and cleaning wall-climbing robots, as an emerging type of operational robot, can stably move on surfaces such as ship surfaces, wind turbine towers, and petrochemical storage tanks. Combined with ultra-high-pressure water jet cleaning devices and recovery systems, they can improve work efficiency, ensure work quality, reduce environmental pollution, and achieve cost control and maximize benefits.

[0003] Currently, most mainstream rust removal and cleaning wall-climbing robots on the market employ permanent magnet adsorption technology and wheeled walking mechanisms. Permanent magnet adsorption technology offers more stable adsorption capabilities, ensuring the robot's safety when moving on walls; wheeled walking mechanisms allow for more flexible movement and turning, and the structure is relatively simple. However, the cleaning devices of these rust removal and cleaning wall-climbing robots are mostly disc-shaped structures with a single rotating body. While they can achieve 360° ultra-high-pressure water jet cleaning within the working area, their cleaning width is limited, and due to structural limitations, cleaning efficiency is low, making them time-consuming and labor-intensive when dealing with large work areas. Utility Model Content

[0004] This application provides a modular vertical traffic platform and construction integration platform, which effectively solves the problem that traditional steel truss platforms have limited vertical traffic and cannot meet the vertical traffic needs between multi-level platforms.

[0005] The present invention solves the above-mentioned technical problems mainly through the following technical solutions: A rust removal and cleaning device is provided, including a cleaning disc and a rotary flushing structure. The cleaning disc has a cleaning chamber with an open lower part and a negative pressure port on the top wall of the cleaning chamber. The rotary flushing structure is provided in two sets and is rotatably installed in the cleaning chamber. The two sets of rotary flushing structures are spaced apart in a first direction across the cleaning disc.

[0006] Furthermore, the negative pressure interface is provided in multiple locations, and the top of the cleaning tray is provided with a negative pressure pipeline connector that is connected to the negative pressure interface.

[0007] Furthermore, the cross-section of the cleaning cavity is oval, and the length direction of the cleaning cavity constitutes the first direction.

[0008] Furthermore, the periphery of the cleaning tray is provided with an annular sealing portion for improving the interfacial sealing of the cleaning chamber in contact with other carriers.

[0009] Furthermore, the sealing part includes an annular top plate, with brushes evenly distributed at the lower end of the top plate, a downwardly extending sealing plate on the outer edge of the top plate, and a flexible sealing sheet for covering gaps connected between the inner edge of the top plate and the cleaning tray.

[0010] Furthermore, the top of the cleaning tray is provided with a sealing cover plate, and a vertically floating floating connection assembly is connected between the edge of the sealing cover plate and the top of the sealing part.

[0011] Furthermore, the floating connection assembly is provided in multiple sets and spaced around the cleaning tray. The floating connection assembly includes a floating rod and an elastic element. The floating rod is arranged vertically, with its lower end connected and fixed to the top of the sealing part. The upper end of the floating rod passes through the sealing cover plate and is connected to a limiting part. The elastic element is connected between the sealing cover plate and the top of the sealing part.

[0012] Furthermore, the rotary rinsing structure includes a cleaning blade holder and a main water inlet pipe. The cleaning blade holder is disposed in the cleaning chamber and has a water channel inside. The bottom or surface of the cleaning blade holder is provided with a jet hole or nozzle connected to the water channel. The main water inlet pipe is vertically fixed to the upper end of the cleaning blade holder and is connected and communicates with the water channel. A rotating body is mounted on the top of the cleaning disc. The main water inlet pipe passes through the top wall of the cleaning chamber and is connected to the rotating body, so that the main water inlet pipe can rotate relative to the cleaning disc under the reaction force of the jet ejected from the jet hole or nozzle.

[0013] The beneficial effects of the rust removal and cleaning device in this application embodiment are as follows: Adopting a dual-rotation flushing structure design, it improves rust removal and cleaning efficiency, reduces time costs, significantly shortens the cleaning cycle, enables wastewater and waste residue recycling, effectively enhances cleaning results, and further improves cleaning efficiency.

[0014] A wall-climbing robot is also provided, including a robot body and the rust removal and cleaning device, which is installed on the robot body.

[0015] Furthermore, the rust removal and cleaning device is inclined relative to the travel direction of the robot body, so that the first direction forms an angle with the normal forward or backward direction of the robot body, and the cleaning areas of the two sets of rotating flushing structures partially overlap in the second direction across the travel direction of the robot body.

[0016] The beneficial effects of the wall-climbing robot in this application embodiment are: With a wide cleaning area, it can efficiently clean walls. At the same time, the inclined rust removal and cleaning device avoids the problem of blind spots in the middle of the cleaning area during the cleaning process. In addition, the inclined arrangement can increase the cleaning range while reducing the overall width, improving the passage. Attached Figure Description

[0024] For details, please refer to Figures 1 to 3 This application provides a rust removal and cleaning device, which mainly includes a cleaning disc 1 and a rotating flushing structure 3.

[0025] The cleaning disc 1 has an "n" shaped (or an inverted U) longitudinal section design, which forms a hollow cavity with an open bottom. This hollow cavity constitutes the cleaning chamber.

[0026] The rotary flushing structure 3 is designed in two sets and is distributed at intervals in the cleaning chamber. Each set of rotary flushing structure 3 is rotatably connected to the top wall of the cleaning chamber. The rotary flushing structure 3 is mainly connected to the flushing pipeline (such as a high-pressure water pipe). During cleaning, high-pressure water is input into the rotary flushing structure 3 of the high-pressure water pipe box, causing the rotary flushing structure 3 to rotate relative to the cleaning chamber and flush the area covered by the cleaning plate 1.

[0027] The spaced distribution of the two sets of rotating flushing structures 3 doubles the cleaning width of the cleaning disc 1, thereby greatly improving cleaning efficiency, shortening the cleaning cycle, and reducing time costs.

[0028] In addition, a negative pressure interface 2 is provided on the top wall of the cleaning tray 1. When in use, the negative pressure interface 2 is connected to the negative pressure equipment. The wastewater and waste residue generated during the cleaning process can be drawn away by the negative pressure generated by the negative pressure equipment, realizing the simultaneous rinsing and recycling of wastewater and waste residue. This improves the shortcomings of traditional technology, which only uses rinsing and requires secondary cleaning of water stains and waste residue.

[0029] Specifically, during cleaning, the lower opening of the cleaning disc 1 is close to the wall of the object to be cleaned. A pipeline for delivering high-pressure water or cleaning fluid is connected to the rotating flushing structure 3. A negative pressure device is connected to the negative pressure interface 2 through the pipeline. The cleaning disc 1 is operated to avoid moving. During the movement, the rotating flushing structure 3 sprays out jets and rotates itself, so that the jets form a circular flushing area. The two sets of rotating flushing structures 3 form two circular flushing areas. The two flushing areas are distributed at intervals in the first direction across the cleaning disc 1, so that the cleaning disc 1 has a large flushing width.

[0030] In some embodiments, multiple negative pressure interfaces 2 can be provided, and the top of the cleaning tray 1 is provided with a negative pressure pipeline connector that connects to the negative pressure interface 2. The negative pressure pipeline connector can be conveniently connected to the negative pressure pipeline of the negative pressure equipment.

[0031] The shape of the negative pressure interface 2 can be flexibly designed according to actual use. It can be designed as a strip opening with a certain length or a circular opening. The negative pressure interface 2 should be designed as close as possible to the edge of the cleaning chamber and should not be located in the center of the rotating flushing structure 3.

[0032] In this embodiment, the edge of the rotating rinsing structure 3 should be as close as possible to the side wall of the cleaning chamber of the cleaning tray 1 during the rotation process, so that the overall size of the cleaning tray 1 is smaller and the structure is more compact, without any extra redundant space.

[0033] In some embodiments, the cleaning chamber has an oval cross-section, with its length forming a first direction. This means that two sets of rotating flushing structures 3 are spaced apart along the length of the cleaning chamber, and the rotation centers of the two sets of rotating flushing structures 3 are located in the middle of the width direction relative to the cleaning chamber. The diameter of the circle containing the edge of the rotating flushing structure 3 during rotation is slightly smaller than the width of the cleaning chamber. The edge of each set of rotating flushing structures 3 during rotation is close to the arcuate walls on opposite sides of the cleaning tray 1, and the edges of the two sets of rotating flushing structures 3 during rotation are close to each other in the middle region of the cleaning chamber. This design allows the two sets of rotating flushing structures 3 to almost cover the entire surface of the cleaning chamber within the cleaning tray 1 during the rotating flushing process, resulting in a better cleaning effect. Furthermore, the oval design of the cleaning chamber, and the matching of the size of this oval shape with the circumferential dimensions of the rotating flushing structures 3 during rotation, allows the overall size of the rust removal and cleaning device to be extremely compact and aesthetically pleasing.

[0034] Of course, the cross-section of the cleaning chamber can also be set to a rectangle, but there will be blind spots for cleaning at the four right corners.

[0035] In actual use, the lower opening of the cleaning tray 1 is close to the wall to be cleaned, but there is a gap between its edge and the wall. Wastewater and waste generated during the cleaning process will overflow through this gap. Therefore, even when rinsing and suctioning wastewater and waste, it is inevitable that wastewater and waste will flow out through the gap between the cleaning tray 1 and the wall. Therefore, in this embodiment, an annular sealing part 4 is provided around the cleaning tray 1 to improve the interface sealing between the cleaning chamber and other carriers. During cleaning, the sealing part 4 fits against the wall, forming a good seal between them, so that wastewater and waste in the cleaning chamber will not overflow through the gap between the cleaning tray 1 and the wall. At the same time, the sealing part 4 can improve the effect of negative pressure suction of wastewater and waste, reduce the energy consumption of negative pressure, and improve the cleaning effect.

[0036] In some embodiments, the sealing part 4 includes an annular top plate 41, with a sealing structure provided at the lower end of the top plate 41. In use, the sealing structure fits against the wall surface, sealing the gap between the cleaning tray 1 and the wall surface. The top plate 41 is connected and assembled with the cleaning tray 1. The gap between the top plate 41 and the cleaning tray 1 is sealed by a flexible sealing sheet. Specifically, an annular sealing sheet is connected between the inner edge of the top plate 41 and the top of the cleaning tray 1, achieving a good sealing of the gap between them.

[0037] In this embodiment, the sealing sheet can be made of rubber.

[0038] In the foregoing embodiments, the sealing structure may be a dense arrangement of brushes 42 at the lower end of the top plate 41, with the brushes 42 extending downwards to at least the same height as or lower than the lower opening of the cleaning tray 1.

[0039] In some other embodiments, a downwardly extending sealing plate 43 is provided on the outer edge of the top plate 41. The lower end of the sealing plate 43 is lower than the lower end of the brush 42. During cleaning, the lower end of the sealing plate 43 is pressed against the wall surface to form a better seal. The sealing plate 43 can be made of rubber or other materials with good sealing properties and a certain degree of flexibility and deformation capability.

[0040] In some other embodiments, the sealing part 4 may be a ring of flexible rubber bladders disposed at the edge of the lower opening of the cleaning tray 1. During cleaning, the rubber bladders are compressed and make good contact with the wall surface to seal.

[0041] Of course, the aforementioned rubber bladder can also be replaced by an annular rubber plate with a certain degree of deformation capability.

[0042] In some embodiments, a sealing cover plate 11 is provided on the top of the cleaning tray 1. A vertically floating floating connecting component 5 is connected between the edge of the sealing cover plate 11 and the top of the sealing part 4, allowing the sealing part 4 to float up and down relative to the cleaning tray 1. With this design, when the cleaning tray 1 approaches the wall surface to be cleaned, the lower part of the sealing part 4 contacts the wall surface first. Furthermore, when subjected to downward displacement or external force, the sealing part 4 experiences an upward reaction force. During this process, the floating connecting component 5 always tends to face the wall surface. Therefore, the sealing part 4 forms an elastic compression contact with the wall surface, effectively improving the sealing performance between the two. At the same time, this design can meet the requirement that when encountering uneven wall surfaces, the sealing part 4 can float up and down relative to the uneven parts of the wall surface, giving the cleaning tray 1 better passage performance relative to the uneven parts of the wall surface.

[0043] It should be noted that when the lower end of the sealing part 4 contacts the wall surface, a vacuum environment is formed, which improves the adhesion between the rust removal and cleaning device and the wall surface under the influence of the internal and external air pressure difference.

[0044] In this embodiment, multiple sets of floating connection components 5 are provided and spaced around the cleaning tray 1, so that the top plate 41 and the cleaning tray 1 can be connected in all directions through the floating connection components 5, and the installation structure of the sealing part 4 on the cleaning tray 1 is relatively stable. At the same time, the design of multiple floating connection components 5 in various directions enables the sealing part 4 to float under pressure at any location.

[0045] In some embodiments, a sealing cover 11 is installed on the top of the cleaning tray 1. The sealing cover 11 has extensions extending to the outside of the cleaning tray 1 at multiple locations along its edge. A floating connection assembly 5 is installed between each extension and the top of the sealing portion 4. The sealing cover 11 has an opening at the location corresponding to the negative pressure interface 2, which does not affect the connection between the negative pressure interface 2 and other pipelines or connectors. Simultaneously, the sealing cover 11 can also have an opening at the location corresponding to the rotary flushing structure 3, without affecting the assembly of the rotary flushing structure 3 and the cleaning tray 1.

[0046] Specifically, the floating connection assembly 5 includes a floating rod 51 and an elastic element 52. The floating rod 51 is vertically arranged, with its lower end fixedly connected to the top of the sealing part 4. The upper end of the floating rod 51 passes through the extension of the sealing cover plate 11 and is connected to a limiting part. The elastic element 52 is connected between the sealing cover plate 11 and the top of the sealing part 4. The elastic element 52 exerts a downward elastic force on the sealing part 4. The limiting part is designed to prevent the upper end of the floating rod 51 from disengaging from the extension when it moves up and down relative to the extension. When the lower end of the sealing part 4 is squeezed by the wall, the floating rod 51 is pushed upward, and the elastic element 52 is squeezed. The elastic element 52 then applies a downward elastic force to the sealing part 4, making the lower end of the sealing part 4 in close contact with the wall, thus achieving a good seal.

[0047] In this embodiment, the limiting part can be a nut, and the upper end of the floating rod 51 is designed to be threaded, with the nut screwed onto the upper end of the floating rod 51. The elastic element 52 can be a spring of a suitable type.

[0048] Of course, the floating connection assembly 5 can also be other structural components with similar functions, such as interlocking rods with springs sleeved on the outside of both.

[0049] In some embodiments, the rotary flushing structure 3 includes a cleaning blade holder 31 and a main water inlet pipe 32. The cleaning blade holder 31 is a rectangular block component with internal water channels. It is horizontally positioned within the cleaning chamber and has multiple jet holes at its bottom connected to the internal water channels. These jet holes are spaced at least in a row between the two ends of its bottom. The jet direction is not vertically downwards, but rather towards one side of the cleaning blade holder 31. Furthermore, the projection of the jet direction onto the horizontal plane is tangential to the circumference of the jet holes during the rotation of the cleaning blade holder 31. The main water inlet pipe 32... The cleaning blade holder 31 is vertically fixed at the center of its upper end and connected to the water channel inside the cleaning blade holder 31. The upper end of the water inlet pipe 32 passes through the top wall of the cleaning disc 1 or the cleaning chamber and is rotatably connected to the top wall of the cleaning disc 1 or the cleaning chamber. In use, high-pressure water is delivered through the upper end of the water inlet pipe 32. After the high-pressure water enters the water channel, it is distributed to each jet hole of the distribution box. Since the jet holes are arranged at an angle, when the high-pressure jet is sprayed out, the reaction force of the jet will push the cleaning blade holder 31 and the water inlet pipe 32 to rotate relative to the cleaning disc 1, forming a "rotating jet" that sprays down to the wall surface, forming a circular rinsing area on the wall surface.

[0050] The top of the cleaning disc 1 is equipped with a rotating body 33, and the upper end of the water inlet pipe 32 is assembled with the rotating body 33 so that the water inlet pipe 32 can rotate relative to the cleaning disc 1 under the reaction force of the jet.

[0051] Specifically, the rotating body 33 can use a bearing of a suitable type, and the main water inlet pipe 32 passes through the inner ring of the bearing and is connected and fixed to the inner ring. A water inlet rotary joint that can rotate relative to the main water inlet pipe 32 is connected to the upper end of the main water inlet pipe, and a high-pressure water pipe is connected to it.

[0052] Of course, in this embodiment, the water inlet main pipe 32 can also be rotatably connected to the top center of the cleaning blade holder 31. In this way, the water inlet main pipe 32 can be fixedly connected to the top wall of the cleaning tray 1 without rotating, and the external high-pressure water pipe can be directly connected to the upper end of the water inlet main pipe 32.

[0053] In some other embodiments, the jet orifice can be replaced with a regular water outlet, and a high-pressure nozzle can be connected to the water outlet. The spray direction of the high-pressure nozzle can be referenced to the direction of the jet orifice. During the rotation of the cleaning blade holder 31, the projection of the spray direction of the high-pressure nozzle in the horizontal plane is tangent to the circumference formed by its rotation, so that the reaction force of the ejected jet can drive the cleaning blade holder 31 to rotate relative to the cleaning disc 1.

[0054] The rust removal and cleaning device in this embodiment can be connected to a long handheld handle on the cleaning tray 1, serving as a conventional handheld rust removal and cleaning device. It can also be integrated as a core cleaning component into a wall-climbing robot to achieve automated and intelligent cleaning and rust removal. Of course, the use of this rust removal and cleaning device is not limited to rust removal and cleaning; it can be used for rinsing any surface with a certain wall thickness.

[0055] When used with a wall-climbing robot, the rust removal and cleaning device is installed on the robot body. As the robot body moves and walks on the wall, it effectively and efficiently cleans the wall surface.

[0056] In some embodiments, the installation of the rust removal and cleaning device on the robot body has the following special design: Please see Figure 4 and Figure 5 The cleaning disc 1 of the rust removal and cleaning device B is tilted relative to the traveling direction of the robot body C. Taking the wall as the horizontal plane as an example, the cleaning disc 1 is tilted relative to the traveling direction s of the robot body in the horizontal plane, so that the first direction m across the cleaning disc 1 forms an angle with the normal forward or backward direction of the robot body. The cleaning areas of the two sets of rotating flushing structures 3 (represented by H in the figure) partially overlap in the second direction n (perpendicular to the forward or backward direction of the robot body) across the traveling direction of the robot body.

[0057] More specifically, the two sets of rotating rinsing structures 3 are distributed in the second direction and are staggered in the direction in which the robot body moves forward or backward. The cleaning areas of the two sets of rotating rinsing structures 3 overlap in the second direction (see...). Figure 6 In the figure, area e refers to the overlapping area of ​​the cleaning areas of the two sets of rotating rinsing structures 3. The advantage of this design is that the two cleaning areas have a small overlap in the middle area of ​​the cleaning disc 1. As the robot moves, there will be no blind spot in the middle of the two overlapping cleaning areas during the cleaning process. In addition, since the cleaning disc 1 is arranged at an angle relative to the forward or backward direction, the actual width of the cleaning disc 1 in the second direction is smaller than the real width of the cleaning disc 1 across the first direction during the forward or backward movement of the robot. That is to say, the width of the cleaning disc 1 when it moves forward or backward is smaller than its real width, which allows the robot to pass through some narrow areas.

[0058] It should be further noted that in this embodiment, the robot body generally includes a main support extending in the aforementioned second direction and two sets of walking mechanisms disposed at both ends of the main support. The rust removal and cleaning device is installed in the middle of the main support and is located between the walking mechanisms at both ends. The walking mechanism uses self-powered wheels, including a smaller front wheel and a larger rear wheel, and has a built-in steering mechanism. All of these walking mechanisms can refer to the powered walking wheels of existing robots in various industries and are considered prior art, so they will not be elaborated upon here.

[0059] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0060] The above provides a detailed description of a rust removal and cleaning device and a wall-climbing robot provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this application. Those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
