[0029] The following is a detailed description of the specific embodiments of the present invention. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0030] In this utility model, unless otherwise stated, directional words such as "upper" and "lower" generally refer to the directions in the assembled and used state. "Inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0031] It should be noted that the terms "first," "second," and the like in the specification and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate for the embodiments of the present invention described herein. In addition, the terms "including" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to these processes, methods, products, or apparatuses.

[0032] like Figure 1 As shown, the present invention provides an exterior wall spraying device, which includes a mounting frame 1, a spraying device 2, a lifting device 3, a soot blowing device 4, a control device and a cleaning device 5. The spraying device 2 is mounted on the mounting frame 1 and is configured to spray paint onto the wall. The lifting device 3 is connected to the mounting frame 1 and can drive the mounting frame 1 to rise and fall. The lifting device 3 is used to be installed on a building. The cleaning device 5 is mounted on the side of the mounting frame 1 facing the wall, and the cleaning device 5 is located below the spraying device 2. The cleaning device 5 is configured to clean dust from the wall. The soot blowing device 4 is mounted on the side of the mounting frame 1 facing the wall, and the soot blowing device 4 is located below the cleaning device 5. The soot blowing device 4 is configured to eject a clean airflow for cleaning the wall. The control device is signal-connected to the lifting device 3, the spraying device 2, the soot blowing device 4 and the cleaning device 5 respectively and can control their operation.

[0033] Specifically, after the lifting device 3 is installed on the building, the mounting frame 1 is connected to the lifting device 3, allowing the lifting device 3 to lift the mounting frame 1. A worker can operate the control device to control the operation of the lifting device 3, which drives the mounting frame 1 down from the top of the building. During the descent of the mounting frame 1, the sootblower 4 installed on the mounting frame 1 can blow a clean airflow, thereby blowing away a portion of the dust on the wall surface. Simultaneously, the cleaning device 5 installed on the mounting frame 1 can clean the dust from the area of ​​the wall surface it passes through, thereby cleaning the remaining dust on the wall surface. Therefore, as the mounting frame 1 descends, the cleaning device 5 cooperates with the sootblower 4 to clean the dust from the wall surface it passes through, preventing the paint from falling off due to dust contamination. Furthermore, when the mounting frame 1 descends to a certain height, the lifting device 3 stops, causing the mounting frame 1 to hover in mid-air. At this time, the spraying device 2 on the mounting frame 1 sprays paint on the unpainted areas of the wall surface. After the spraying is completed in the area, the lifting device 3 drives the mounting frame 1 to continue to descend, and this process is repeated until the entire wall surface is sprayed. Therefore, in the exterior wall spraying equipment of the present invention, the cleaning device 5 and the soot blowing device 4 can clean the wall surface, and the spraying device 2 can spray the wall surface, thereby realizing the mechanized operation of wall cleaning and painting, and can replace manual labor to work at a stable rate, thereby overcoming the problems of high labor intensity and low construction efficiency when manually painting the exterior walls of buildings.

[0034] In some embodiments, the lifting device 3 includes a hoist 31 and a guide mechanism 32. The hoist 31 is used to be installed on the top of a building. The reverse rotation of the drum of the hoist 31 can release the rope wound on the drum, and the forward rotation of the drum of the hoist 31 can retract the rope wound on the drum. The guide mechanism 32 includes a first guide wheel 321 and a second guide wheel 322. The first guide wheel 321 is installed on the side of the guide mechanism 32 facing the hoist 31, and the second guide wheel 322 is installed on the side of the guide mechanism 32 facing away from the hoist 31 and extends horizontally outside the building. By placing the rope of the hoist 31 on the first guide wheel 321 and the second guide wheel 322 in sequence, the rope of the hoist 31 can pull the mounting frame 1 up and down in a direction parallel to the wall.

[0035] Of course, the lifting device 3 can be in any form that can achieve its function, and the present invention does not impose any limitation thereto.

[0036] In addition, the exterior wall spraying equipment is provided with a power supply installed in the mounting frame 1 to supply power to the control device, and a conductive wire may be used to electrically connect the control device.

[0037] like Figure 2As shown, in some embodiments of the present invention, the cleaning device 5 includes a cleaning brush head 52 and two support rods 51, the head end of the support rod 51 is connected to the side of the mounting frame 1 facing the wall, the two support rods 51 are spaced apart and parallel to each other in the length direction of the mounting frame 1, and the cleaning brush head 52 is connected to the ends of the two support rods 51 and extends along the length direction of the mounting frame 1.

[0038] Specifically, during the descending process of the mounting bracket 1 , the cleaning brush head 52 contacts the wall surface and moves downward along the wall surface, thereby generating friction on the wall surface and cleaning the dust attached to the wall surface.

[0039] It should be noted that the cleaning brush head 52 can adopt any form that can achieve a cleaning effect, and the present invention does not impose any limitation.

[0040] like Figure 3 As shown, in some embodiments of the present invention, the cleaning device 5 also includes a dust shield 53, and the two sides of the dust shield 53 in the length direction of the mounting frame 1 are sealed with the two support rods 51 respectively, and the side of the dust shield 53 facing the wall is sealed with the side of the cleaning brush head 52 facing away from the wall.

[0041] Specifically, for two adjacent wall areas, when the exterior wall spraying equipment is in operation, while the cleaning device 5 is cleaning the lower wall, the spraying device 2 is simultaneously spraying the upper wall. When the cleaning device 5 is cleaning the lower wall, the diffuse dust will be blown everywhere by the wind, and may adhere to the upper wall that has been sprayed and combine with the paint, resulting in poor spraying effect. The dust shield 53 separates the cleaning device 5 from the spraying device 2 above the cleaning device 5, which can effectively prevent the dust that has been cleaned from flying upwards, thereby preventing the dust from damaging the sprayed wall part.

[0042] like Figure 7 As shown, in some embodiments of the present invention, the support rod 51 extends downwardly from its head end to its tail end and gradually moves away from the mounting frame 1.

[0043] Specifically, the support rod 51 is installed on the mounting frame 1 at an angle downward, so that the angle between the support rod 51 and the side of the mounting frame 1 below the support rod 51 facing the wall is set to an acute angle, which can increase the friction between the cleaning brush head and the wall in relative motion, help to clean more stubborn dust on the wall, and improve the cleaning effect.

[0044] like Figure 4As shown, in some embodiments of the present invention, the middle parts of the two support rods 51 are connected by a cross bar, the dust shield 53 is fixedly connected to the cross bar, and the head end of the support rod 51 is rotatably connected to the mounting frame 1; the cleaning device 5 also includes a driving cylinder 54 located above the dust shield 53, the fixed part of the driving cylinder 54 is fixedly connected to the mounting frame 1, the driving rod of the driving cylinder 54 is hinged to the middle part of the cross bar, the driving cylinder 54 extends obliquely and can drive the support rod 51 to rotate vertically, and the driving cylinder 54 is connected to the control device signal.

[0045] Specifically, a cross bar is provided between the two support rods 51 to connect the two, which can enhance the structural strength of the cleaning device and make the cleaning brush head less likely to shake when cleaning the wall. Since the support rod 51 is rotatably connected to the mounting frame 1, the cleaning device can be folded up and placed close to the side of the mounting frame 1 facing the wall when the exterior wall spraying equipment is not in use. When the cleaning device is used, the driving cylinder 54 is controlled by the control device to extend the driving rod, and the driving rod pushes the cross bar, so that the cleaning device is rotated toward the wall. When the cleaning brush head can clean the wall, the driving rod stops extending. In addition, the cleaning device with the support rod 51 rotatably connected to the mounting frame 1 can better adapt to the construction of different walls. When the distance between the mounting frame 1 and the wall changes, the angle of the support rod 51 and the mounting frame 1 facing the wall can be adjusted by the driving cylinder 54, thereby adjusting the horizontal distance of the cleaning brush head to the wall.

[0046] like Figure 6 As shown, in some embodiments of the present invention, the cleaning brush head 52 includes a roller and a cylindrical cleaning brush sleeved on the outside of the roller, and both ends of the roller are rotatably connected to the ends of the two support rods 51.

[0047] Specifically, when the mounting bracket 1 is raised or lowered parallel to the wall, the cylindrical cleaning brush rolls on the wall and cleans the dust on the wall.

[0048] In some embodiments of the present invention, the soot blowing device 4 includes a jet air pump 42 and a plurality of soot blowing nozzles 41. The jet air pump 42 is arranged inside the mounting frame 1, and the jet air pump 42 is connected to the control device signal; the soot blowing nozzle 41 is connected to the side of the mounting frame 1 facing the wall, and the soot blowing nozzle 41 is connected to the jet air pump 42; the air inlet end of the soot blowing nozzle 41 is higher than the jet end of the soot blowing nozzle 41 so that it can spray a clean air flow that flows obliquely downward and is used to clean the wall, and the plurality of soot blowing nozzles 41 are spaced apart in the length direction of the mounting frame 1.

[0049] Specifically, as the mounting frame 1 descends, the control device controls the air jet pump 42 to compress the air so that the sootblowing nozzle 41 sprays a clean air stream toward the wall, thereby achieving the purpose of preliminary cleaning of the wall. To prevent dust from flying upward, the air inlet end of the sootblowing nozzle 41 is positioned higher than the air outlet end of the sootblowing nozzle 41. At the same time, the sootblowing nozzle 41 sprays downwardly from the wall, allowing the sootblowing device 4 to achieve a wider cleaning range.

[0050] In some embodiments of the present invention, a row of roller mechanisms 12 capable of pressing against a wall and rolling along the wall are respectively provided on both sides of the mounting frame 1 in the longitudinal direction.

[0051] Specifically, after the hoisting device 3 lifts the mounting frame 1, a row of roller mechanisms 12 are provided on either side of the mounting frame 1 along its length to prevent the portion of the mounting frame 1 facing the wall from getting too close to the wall during the lifting process or colliding with the wall, thereby damaging the wall or the exterior wall spraying equipment. When the mounting frame 1 is raised or lowered, the roller mechanisms 12 press against the wall and roll along the wall, effectively preventing the mounting frame 1 from colliding with the wall.

[0052] In addition, the roller mechanism 12 includes a mounting rod and a roller. The head end of the mounting rod is connected to the mounting frame 1, and the roller is rotatably connected to the end of the mounting rod.

[0053] In some embodiments of the present invention, two lifting rings 11 are provided on the top of the side of the mounting frame 1 facing away from the wall; the two lifting rings 11 are spaced apart and symmetrically distributed in the length direction of the mounting frame 1; and the lifting device 3 is detachably connected to the two lifting rings 11.

[0054] Specifically, before using the exterior wall spraying equipment, the rope hanging from the second guide wheel 322 of the lifting device 3 is connected to the mounting frame 1 through the lifting ring 11 of the mounting frame 1, and then the lifting device 3 can lift the mounting frame 1 up and down. The symmetrically arranged lifting rings 11 can ensure the stability of the mounting frame 1 during the lifting process.

[0055] like Figure 5 As shown, in some embodiments of the present invention, the spraying device 2 includes a rodless cylinder 23, a paint nozzle 21 and a paint providing device 22. The guide rail 231 of the rodless cylinder 23 is fixedly mounted on the mounting frame 1. The guide rail 231 of the rodless cylinder 23 extends along the length direction of the mounting frame 1. The paint nozzle 21 is fixedly mounted on the sliding platform 232 of the rodless cylinder 23. The paint providing device 22 is installed in the mounting frame 1. The paint providing device 22 is connected to the paint nozzle 21 so as to provide paint to the paint nozzle 21.

[0056] Specifically, each time the mounting frame 1 is lowered a certain distance, the hoist 31 of the lifting device 3 stops, and the mounting frame 1 becomes suspended in mid-air. The control device then drives the spraying device 2 to operate, and the paint supply device 22 continuously supplies paint to the paint nozzle 21. The nozzle moves along the guide rail 231 with the sliding platform 232 while spraying the wall. When the nozzle sprays from one end of the guide rail 231 to the other end of the guide rail 231, the paint supply device 22 stops supplying paint to the paint nozzle 21, and the spraying is completed. The control device then controls the lifting device 3 to lower the mounting frame 1 again a certain distance, and then stops descending, and the spraying process is repeated. This process is repeated until the wall is finally sprayed.

[0057] It should be noted that the height to which the mounting bracket 1 is lowered at one time depends on the vertical spraying range of the paint nozzle 21. In the actual use of the exterior wall spraying equipment, the single lowering height and the total lowering height of the mounting bracket 1 can be adjusted through the control device according to the performance of the paint nozzle 21 used.

[0058] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0059] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0060] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
