[0030] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0031] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are orientations or positional relationships based on the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0033] The terms "first", "second" and "third" (if any) in the specification and claims of this application and the above drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0034] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0035] The wall-climbing robot has the functions of adsorption, movement, and operation. It can be used for special operations on vertical or curved walls, and is also called a wall-moving robot. Wall-climbing robots are widely used in flaw detection or painting of large petrochemical storage tanks, building cleaning and spraying, ship rust removal, inspection and thickness measurement in the nuclear industry, etc. They can also be used in industries such as bridges and tunnels and wind power. In the prior art, the wall-climbing robot includes a body and a spraying assembly mounted on the body, which is adsorbed on the wall through the body and walks on the wall. The spraying assembly is provided with multiple nozzles, and the wall on which the wall-climbing robot walks can be painted or sprayed with oil through the multiple nozzles. However, the surface of the steel mold has a certain curvature change, and the spraying method cannot adapt to the curved wall with curvature change, and it is difficult to ensure the consistency of the oiling effect, that is, it is difficult to ensure that the oil is evenly coated on the surface of the steel mold.

[0036] After repeated thinking and verification, the inventor found that if the oiling wall-climbing robot uses two roller brush assemblies to oil the walking wall surface of the oiling wall-climbing robot, the roller brush assembly is connected to the body through a connecting rod and a rocker arm, and an elastic member is arranged between the connecting rod and the body, and the two roller brush assemblies are respectively arranged at the two ends of the rocker arm. The two roller brush assemblies are respectively pressed against the walking wall surface of the oiling wall-climbing robot through the elastic force of the elastic member. In this way, the oiling wall-climbing robot can adapt to the changes in the curvature of the wall, the oiling wall-climbing robot can realize the oiling of the steel mold surface and ensure the consistency of the oiling effect.

[0037] In view of this, the inventor has designed an oiling wall-climbing robot, which can be adsorbed on the surface of the steel mold and walk on the surface of the steel mold through the vehicle body. The oil supply unit of the oil supply assembly can provide oil to the two roller brush units of the roller brush assembly respectively. The two roller brush units of the roller brush assembly are connected to the bracket of the oil supply assembly through a connecting rod and a rocker arm, and an elastic member is connected between the bracket and the connecting rod, and the two roller brush units are respectively arranged at both ends of the rocker arm. When the oiling wall-climbing robot walks on the surface of the steel mold to a position where the curvature changes, the two roller brush units can still reliably adhere to the surface of the steel mold, so as to achieve uniform oiling of the surface of the steel mold.

[0038] The technical solution of the oiled wall-climbing robot provided in the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0039] Reference Figures 1 to 3 As shown, the oiling wall-climbing robot provided by the embodiment of the present application includes a vehicle body 100, an oil supply assembly 200 and a roller brush assembly 300. The oil supply assembly 200 includes a bracket 210 and an oil supply unit 220 mounted on the bracket 210, and the bracket 210 is mounted on the vehicle body 100. The roller brush assembly 300 includes two connecting rods 310, two swing rods 320, a first roller brush unit 330, a second roller brush unit 340 and an elastic member 350. The first ends of the two connecting rods 310 are respectively rotatably mounted on both sides of the bracket 210, and the middle parts of the two swing rods 320 are respectively rotatably connected to the second ends of the two connecting rods 310. The first roller brush unit 330 and the second roller brush unit 340 are respectively connected to the oil supply unit 220, and the two ends of the first roller brush unit 330 are respectively connected to the first ends of the two swing rods 320, and the two ends of the second roller brush unit 340 are respectively connected to the second ends of the two swing rods 320. The elastic member 350 is connected between the connecting rod 310 and the bracket 210. The oil supply unit 220 is configured to supply oil to the first roller brush unit 330 and the second roller brush unit 340 respectively, and the elastic member 350 is configured to drive the second end of the connecting rod 310 to move toward the direction close to the walking wall of the oil-applied wall-climbing robot.

[0040] The vehicle body 100 has the functions of adsorption and movement, and can be adsorbed on a metal wall surface, such as the steel mold surface of the secondary lining trolley, and move, driving the oil supply assembly 200 and the roller brush assembly 300 to move together. This embodiment does not limit the specific structure of the vehicle body 100, and those skilled in the art can select a suitable vehicle body 100 according to actual needs.

[0041] For example, Figure 1 and Figure 2 As shown, the bracket 210 of the oil supply assembly 200 may include a support portion and a second mounting portion 213 located on the side of the support portion facing the vehicle body 100. The second mounting portion 213 may be connected to the vehicle body 100 via a mounting pin 240, and the oil supply unit 220 may be fixedly mounted on the top of the support portion.

[0042] In a possible implementation, in the width direction of the oil-coated wall-climbing robot, seat bearings 391 are installed on opposite sides of the top of the bracket 210, and the first ends of the two connecting rods 310 are connected to the two seat bearings 391 through the first pin shafts 392, so that the two connecting rods 310 can rotate around the corresponding first pin shafts 392. The two swing rods 320 can be connected to the second ends of the two connecting rods 310 through the second pin shafts 393, so that the swing rods 320 can rotate around the second ends of the corresponding connecting rods 310.

[0043] It can be understood that after the first roller brush unit 330 and the second roller brush unit 340 are respectively connected to the oil supply unit 220 of the oil supply assembly 200, the oil supply assembly 200 can respectively supply oil to the first roller brush unit 330 and the second roller brush unit 340. When the swing arm 320 rotates relative to the connecting rod 310, the relative position between the first roller brush unit 330 and the second roller brush unit 340 can be adjusted, so that the first roller brush unit 330 and the second roller brush unit 340 can adapt to the curvature change of the wall surface, that is, when the wall surface changes, the first roller brush unit 330 and the second roller brush unit 340 can reliably contact the wall surface.

[0044] For example, a tension spring may be used as the elastic member 350, and an elastic member 350 is disposed between each connecting rod 310 and the bracket 210. In a possible implementation, Figure 2 and Figure 3 As shown, the positions of the two connecting rods 310 near the first ends are respectively provided with first pillars 311, the top of the bracket 210 is respectively provided with second pillars 212 on both sides in the width direction of the oiling wall-climbing robot, and the two ends of the elastic member 350 are respectively connected to the first pillar 311 and the second pillar 212. When the oiling wall-climbing robot walks on the wall, the elastic force of the elastic member 350 and the gravity of the roller brush assembly 300 can make the first roller brush unit 330 and the second roller brush unit 340 respectively close to the wall surface, thereby ensuring the consistency of the oiling effect.

[0045] The oiling wall-climbing robot provided in this embodiment has a body 100 that can provide walking and adsorption functions, driving the oiling wall-climbing robot to move on the wall. The roller brush assembly 300 is connected to the bracket 210 of the oil supply assembly 200, and the roller brush assembly 300 includes two connecting rods 310, two swing rods 320, a first roller brush unit 330, a second roller brush unit 340 and an elastic member 350. The roller brush assembly 300 can rotate relative to the bracket 210 through the two connecting rods 310, and the swing rod 320 can rotate relative to the corresponding connecting rod 310. The first roller brush unit 330 and the second roller brush unit 340 on the swing rod 320 can be closely attached to the walking wall surface of the oiling wall-climbing robot, i.e., the steel mold surface, through the rotation of the swing rod 320 and the elastic force provided by the elastic member 350. The oil supply unit 220 of the oil supply assembly 200 can provide oil to the first roller brush unit 330 and the second roller brush unit 340 respectively. In this way, when the oiling wall-climbing robot walks on the surface of the steel mold, the first roller brush unit 330 and the second roller brush unit 340 can adapt to the curvature change of the steel mold surface. The first roller brush unit 330 and the second roller brush unit 340 are respectively pressed against the surface of the steel mold to apply oil (mainly release agent) to the surface of the steel mold to facilitate lining demoulding and ensure the consistency of the oiling effect.

[0046] In addition, the oiling wall-climbing robot provided by the present application has a simple and compact structure and can perform oiling operations in a narrow space. The oiling wall-climbing robot oils the wall surface through the first roller brush unit 330 and the second roller brush unit 340, and can also avoid splashing of oil.

[0047] In one embodiment, Figure 2 and Figure 3 As shown, the first roller brush unit 330 includes a first tube body 331 and three first roller brushes 332 spaced apart on the first tube body 331. Each first roller brush 332 is connected to the first tube body 331, and the two ends of the first tube body 331 are respectively connected to the first ends of the two swing rods 320. The second roller brush unit 340 includes a second tube body 341 and two second roller brushes 342 spaced apart on the second tube body 341. Each second roller brush 342 is connected to the second tube body 341, and the two ends of the second tube body 341 are respectively connected to the second ends of the two swing rods 320. In the walking direction of the oiling wall-climbing robot, the three first roller brushes 332 and the two second roller brushes 342 are arranged alternately, and the rolling area of ​​the first roller brush 332 partially overlaps with the rolling area of ​​the second roller brush 342.

[0048] The present embodiment does not limit the interval between two adjacent first roller brushes 332 and the interval between two adjacent second roller brushes 342 , and those skilled in the art may set them according to actual needs.

[0049] The first tube body 331 and the second tube body 341 are both hard tubes with a certain rigidity. Each first roller brush 332 can rotate relative to the first tube body 331 on the first tube body 331, and each second roller brush 342 can rotate relative to the second tube body 341 on the second tube body 341. The two ends of the first tube body 331 can be fixedly connected to the first ends of the two swing rods 320, respectively, and the two ends of the second tube body 341 can be fixedly connected to the second ends of the two swing rods 320, respectively. When the oiling wall-climbing robot walks on the wall, each first roller brush 332 and each second roller brush 342 are in close contact with the wall. As the oiling wall-climbing robot walks, each first roller brush 332 and each second roller brush 342 roll on the wall to achieve uniform oiling of the wall.

[0050] It can be understood that the three roller brushes of the first roller brush unit 330 and the two roller brushes of the second roller brush unit 340 are arranged alternately in front and back, and two of them are partially overlapped.

[0051] Through the above arrangement, when the first roller brush 332 and the second roller brush 342 roll on the wall, the wall can be oiled and the oiling area can be guaranteed. When the oiling wall-climbing robot walks on the wall, the oiling area of ​​the roller brush assembly 300 can be completely covered, which is convenient for the oiling wall-climbing robot to oil the wall.

[0052] In a specific embodiment, Figure 2 and Figure 3 As shown, the roller brush assembly 300 also includes a connection unit 360, which includes a four-way joint 361, a first connection pipe 362 and two second connection pipes 363. The first interface of the four-way joint 361 is connected to the oil supply unit 220, and the second interface of the four-way joint 361 is connected to the second tube body 341 through the first connection pipe 362. One end of the first connection pipe 362 connected to the second tube body 341 is located between the two second roller brushes 342. The third interface and the fourth interface of the four-way joint 361 are respectively connected to the first tube body 331 through the two second connection pipes 363, and the first tube body 331 is respectively connected to a second connection pipe 363 at the position between two adjacent first roller brushes 332.

[0053] Exemplarily, the first interface and the second interface of the four-way joint 361 are arranged opposite to each other, and the third interface and the fourth interface are arranged opposite to each other. Schematically, the first connecting pipe 362 and the second connecting pipe 363 are both hard pipes with a certain rigidity, and the first connecting pipe 362 and the second connecting pipe 363 can both be "L"-shaped structures, one end of the "L"-shaped structure is connected to the corresponding interface of the four-way joint 361, and the other end of the "L"-shaped structure is connected to the corresponding pipe body. Figure 2 and Figure 3 As shown, one end of the first connecting tube 362 away from the four-way joint 361 can be connected to the second tube body 341 through a three-way joint 364, and one end of each second connecting tube 363 away from the four-way joint 361 can be connected to the first tube body 331 through a three-way joint 364.

[0054] When the oil provided by the oil supply unit 220 enters the second tube body 341 via the four-way joint 361 and the first connecting pipe 362, the oil entering the second tube body 341 flows to both ends of the second tube body 341, thereby providing oil to the two second roller brushes 342 on the second tube body 341. When the oil provided by the oil supply unit 220 enters the first tube body 331 via the four-way joint 361 and the second connecting pipe 363, the oil entering the first tube body 331 flows from the liquid outlet of the second connecting pipe 363 to both ends of the first tube body 331. In this way, by connecting the four-way joint 361 and the first tube body 331 through two second connecting pipes 363, oil can be provided to the three first roller brushes 332 on the first tube body 331 respectively.

[0055] Through the above arrangement, the oil supply unit 220 can provide oil to each first roller brush 332 and each second roller brush 342 respectively through the connecting unit 360, ensuring that the oiling wall-climbing robot can reliably oil the wall surface when walking on the wall surface.

[0056] In a more specific embodiment, Figure 2 and Figure 3As shown, a first regulating valve 371 is provided on the first connecting pipe 362 , and a second regulating valve 372 is provided respectively at a position between the first roller brush 332 located in the middle of the first tube body 331 and the two second connecting pipes 363 .

[0057] The structure of the first regulating valve 371 can be the same as that of the second regulating valve 372. The present embodiment does not limit the specific structures of the first regulating valve 371 and the second regulating valve 372, and those skilled in the art can set them as needed. By adjusting the first regulating valve 371, the flow of the first connecting pipe 362 can be adjusted, thereby adjusting the ratio between the amount of oil entering the first pipe body 331 and the amount of oil entering the second pipe body 341. Figure 3 As shown, two second regulating valves 372 are arranged on the first tube body 331, the second regulating valve 372 on the left side is between the liquid outlet of the second connecting pipe 363 on the left side and the first roller brush 332 in the middle, and the second regulating valve 372 on the right side is between the liquid outlet of the second connecting pipe 363 on the right side and the first roller brush 332 in the middle. After the oil enters the first tube body 331 from the second connecting pipe 363 on the left side, the second regulating valve 372 on the left side can adjust the ratio between the amount of oil flowing to the left and the amount of oil flowing to the right from the second connecting pipe 363 into the first tube body 331. After the oil enters the first tube body 331 from the second connecting pipe 363 on the right side, the second regulating valve 372 on the right side can adjust the ratio between the amount of oil flowing to the left and the amount of oil flowing to the right from the second connecting pipe 363 into the first tube body 331.

[0058] This structure can adjust the oil flow rate flowing through the corresponding pipelines by adjusting the first regulating valve 371 and the two second regulating valves 372, so as to flexibly distribute the oil amount of each roller brush, improve the versatility of the oiling wall-climbing robot, and ensure the oiling effect of the oiling wall-climbing robot.

[0059] Optional, such as Figure 2 and Figure 3 As shown, fixing rings 381 are respectively disposed on opposite sides of each first roller brush 332 and opposite sides of each second roller brush 342 .

[0060] Specifically, the two fixing rings 381 located on both sides of each first roller brush 332 are fixed to the first tube body 331, and the two fixing rings 381 located on both sides of each second roller brush 342 are fixed to the second tube body 341. Schematically, the fixing ring 381 includes two arc segments. When the two arc segments are set on the corresponding tube body, the two arc segments can be locked using fasteners to fix the fixing ring 381 on the corresponding tube body. It is worth mentioning that the two ends of each first roller brush 332 and the two ends of each second roller brush 342 are respectively against the corresponding fixing ring 381.

[0061] By setting a fixing ring 381, the fixing ring 381 is used to limit the positions of the first roller brush 332 and the second roller brush 342, so as to avoid the axial movement of the first roller brush 332 along the first tube body 331 and the axial movement of the second roller brush 342 along the second tube body 341, thereby ensuring the oiling effect and uniformity of the oiling wall-climbing robot.

[0062] Optional, such as Figure 2 and Figure 3 As shown, plugs 382 are respectively provided at both ends of the first tube body 331 and the second tube body 341 , and the ends of the corresponding tube bodies can be sealed by the plugs 382 .

[0063] In a specific implementation, an oil outlet is provided at a position where the first roller brush 332 is sleeved on the first tube body 331 and at a position where the second roller brush 342 is sleeved on the second tube body 341 .

[0064] The shape and size of the oil outlet can be set as needed and are not limited here. The first tube body 331 is provided with an oil outlet at a position corresponding to each first roller brush 332, and the first roller brush 332 covers the corresponding oil outlet on the first tube body 331. The second tube body 341 is provided with an oil outlet at a position corresponding to each second roller brush 342, and the second roller brush 342 covers the corresponding oil outlet on the second tube body 341.

[0065] Through the above arrangement, the oil in the first tube body 331 can flow to the corresponding first roller brush 332 through the oil outlet, and the oil in the second tube body 341 can flow to the corresponding second roller brush 342 through the oil outlet, so that the first roller brush 332 and the second roller brush 342 can oil the wall surface when rolling on the wall surface.

[0066] like Figure 2 As shown, an oil shielding assembly 400 is installed on the bracket 210 , and the oil shielding assembly 400 is located between the vehicle body 100 and the roller brush assembly 300 .

[0067] The width of the oil shielding assembly 400 is not less than the width of the vehicle body 100. When the oil-coated wall-climbing robot walks on the wall, the end of the oil shielding assembly 400 faces the wall, and those skilled in the art can set the distance between the end of the oil shielding assembly 400 and the wall as needed, which is not limited here.

[0068] The oil blocking assembly 400 can block the oil and prevent the wheels of the vehicle body 100 from being contaminated by excessive oil at the roller brush assembly 300. The wheels are not easily contaminated by the oil and slip, thus preventing the oiled wall-climbing machine from falling off the wall and causing safety problems, thereby ensuring the reliability of the oiling of the oiled wall-climbing robot.

[0069] In a specific embodiment, Figure 2As shown, the oil baffle assembly 400 includes a pressing sheet 410 and a baffle 420. A first mounting portion 211 is provided on the side of the bracket 210 facing away from the roller brush assembly 300, and the baffle 420 is clamped between the pressing sheet 410 and the first mounting portion 211. One end of the baffle 420 facing the walking wall exceeds the pressing sheet 410 and the first mounting portion 211 respectively.

[0070] The baffle 420 may be made of an elastic material such as silicone or rubber. The first mounting portion 211 may be located at the bottom of the bracket 210 on a side close to the vehicle body 100. When the baffle 420 is clamped between the pressing plate 410 and the first mounting portion 211, a fastener may be used to lock the pressing plate 410 on the first mounting portion 211. Schematically, the width of the baffle 420 is not less than the width of the vehicle body 100 to ensure that the baffle 420 can reliably block the oil.

[0071] This structure utilizes the baffle plate 420 to block the oil, so that the wheels of the vehicle body 100 are not easily contaminated by the oil and slip. In addition, the baffle plate 420 and the first mounting portion 211 can reliably fix the baffle plate 420 to prevent the baffle plate 420 from covering the position relative to the vehicle body 100 and affecting the blocking effect of the oil.

[0072] In one embodiment, Figure 2 and Figure 3 As shown, the oil supply unit 220 includes an oil pump 221 and an oil pipe 222. The oil pump 221 is installed on the bracket 210. One end of the oil pipe 222 is connected to the oil pump 221, and the other end of the oil pipe 222 is connected to the first roller brush unit 330 and the second roller brush unit 340 respectively.

[0073] The oil pump 221 can be fixedly mounted on the bracket 210 by fasteners, and the oil can enter the first roller brush unit 330 and the second roller brush unit 340 through the oil pipe 222 under the drive of the oil pump 221. When the roller brush assembly 300 is provided with a connecting unit 360, the end of the oil pipe 222 away from the oil pump 221 can be connected to the first interface of the four-way joint 361 of the connecting unit 360.

[0074] In one possible implementation, Figure 2 and Figure 3 As shown, the bracket 210 may be provided with an oil bag 223, through which oil can be stored, and the oil pump 221 may be connected to the oil bag 223, so that the oil pump 221 can drive the oil in the oil bag 223 into the first roller brush unit 330 and the second roller brush unit 340. In another possible implementation, the oil pump 221 may be connected to an external oil supply device through a pipeline, and the external oil supply device supplies oil to the first roller brush unit 330 and the second roller brush unit 340 respectively.

[0075] like Figure 2As shown, a third regulating valve 224 may be provided on the oil pipe 222 , and the amount of oil output by the oil supply unit 220 may be controlled by the third regulating valve 224 .

[0076] With this structure, the oil can be supplied to the first roller brush unit 330 and the second roller brush unit 340 through the oil pipe 222 under the driving of the oil pump 221 .

[0077] In a specific embodiment, Figure 1 and Figure 2 As shown, the oil supply assembly 200 further includes a cover shell 230 , which is mounted on the bracket 210 and covers the outer side of the oil pump 221 , and the oil pipe 222 is disposed through the cover shell 230 .

[0078] The cover 230 can be mounted on the bracket 210 by fasteners. When the oil-applied wall-climbing robot is provided with an oil bag 223, the oil bag 223 and the oil pump 221 are both located inside the cover 230. Schematically, a hole for the oil supply pipe 222 to pass through is provided on the side wall of the cover 230. After the oil pipe 222 passes through the hole on the cover 230, it can connect the oil pump 221 in the cover 230 and the roller brush assembly 300 outside the cover 230. Optionally, the two connecting rods 310 of the roller brush assembly 300 are respectively located on opposite sides of the outside of the cover 230.

[0079] By providing the cover 230, when the oil bag 223 is provided on the bracket 210, the cover 230 can be used to cover the oil pump 221 and the oil bag 223, which on the one hand improves the aesthetics of the oil-coated wall-climbing robot, and on the other hand, the cover 230 can also prevent the oil pump 221 and the oil bag 223 from contacting external impurities, thereby ensuring the service life of the oil pump 221 and the oil bag 223.
