Description

Technical Field

[0001] This invention relates to a working equipment for working at heights, and more particularly to a building facade working platform. This platform, based on a rope system, can carry different working components to treat the exterior facade of a building. Specifically, it relates to both a contact surface treatment device based on this building facade working platform and a non-contact surface treatment device based on the platform. Background Technology

[0002] The maintenance of facades for high-rise and super high-rise buildings is a crucial aspect of building operations. This maintenance, in addition to cleaning, may involve facade paint renovation, exterior insulation spraying, facade stone cladding, and the detection and repair of facade hollow areas. Taking the routine cleaning of glass curtain walls, one of the most common tasks, as an example, the purpose of cleaning glass curtain walls is not only to beautify the environment and maintain the building's clean appearance, but more importantly, to remove contaminants, protect the glass and sealant from acid rain or dust corrosion, and extend the lifespan of the curtain wall. Currently, common methods include manual cleaning, building maintenance units (BMUs) using window cleaning machines or suspended platforms, and more automated window cleaning robots. Because cleaning building glass curtain walls is a high-risk and highly specialized operation, while manual cleaning is more flexible and can adapt to various complex facade structures, it is still highly dangerous due to the significant impact of outdoor temperature, humidity, wind speed, and other weather factors on high-altitude operations, in addition to the skill and experience of the workers. Therefore, it is expected that manual cleaning will gradually decrease in proportion and eventually be phased out in this application scenario. In contrast, window cleaning machines or suspended platforms utilize specialized rooftop cleaning equipment or platforms as personnel carriers. Workers operate cleaning tools from these platforms, offering higher safety and stability than rope work. They can also carry more tools and equipment, making them suitable for high-rise buildings and currently the most widely used solution for cleaning glass curtain walls. However, their disadvantages are also significant. First, their cost is extremely high, significantly increasing building maintenance costs. Second, although workers stand on platforms like suspended platforms, they are still exposed to height, strong winds, and extreme weather, posing risks such as falling objects, accidental operational errors, or sudden illnesses. Furthermore, the weight of the equipment, combined with the workers' weight, places strict requirements on the building's roof structure's load-bearing capacity during lifting control, whether using a winch at the platform or on the roof. Considering translational movement, the space and layout of the building's roof are also subject to stringent limitations. Therefore, it is clear that there is still room for improvement in the current BMU (Bridge Cleaning Unit) or suspended platform solutions. Window cleaning robot systems represent a more intelligent solution proposed by some manufacturers. Unlike the two solutions mentioned above, these systems mostly use negative pressure adsorption to attach specially designed intelligent window cleaning robots to the glass curtain wall for cleaning operations. This process does not require operators to actually work at heights, but can be achieved through remote control.Compared to the first two methods, it can significantly improve personnel safety, but it is only applicable to the outer surface of glass curtain walls and also has some problems. For example, the equipment cost is relatively high, and due to the characteristics of negative pressure adsorption, it has high requirements for the flatness of the glass surface. In addition, compared with manual treatment, its cleaning ability is not ideal, especially for stubborn stains with strong adhesion.

[0003] It is evident that existing technologies have some shortcomings when working on the facades of high-rise buildings and urgently need improvement. Summary of the Invention

[0019] Preferably, the main column is provided with a lifting slide rail, and the slide table is slidably mounted on the lifting slide rail to give it a second degree of freedom of movement in the second direction, wherein the first direction is perpendicular to the second direction.

[0022] In a second aspect, the present invention also provides a surface treatment device for building facades, the surface treatment device comprising a building facade working platform as described above and a brush head configured as the working part, wherein the thrust generating mechanism generates a thrust acting on the sliding unit during operation to cause the brush head to contact the building facade with a preset pressure, and the brush head includes at least a brush head frame and a brush head body disposed on the brush head frame.

[0023] Preferably, the brush head also includes a liquid distribution mechanism for providing liquid during contact surface treatment.

[0024] Preferably, the liquid distribution mechanism includes a material tank and a spray head connected to the material tank via a liquid pipe, the spray head being configured to spray material onto the exterior facade of the building.

[0025] Preferably, the brush head is constructed as a roller brush assembly, which includes a spindle and a brush body covering the spindle. The spindle is a hollow structure with seepage holes on its outer periphery to facilitate the seepage of liquid and a liquid inlet connector for conveying liquid into the spindle. The liquid inlet connector and the spindle together constitute the spray head.

[0026] Preferably, the brush head further includes a rotation adjustment mechanism, which includes a torsion motor connected to the sliding unit.

When the swing arm swings, the brush head can enter a first state where the brush head contacts the surface to be treated, or enter a second state where the scraper contacts the surface to be treated.

[0028] A third aspect of the present invention also provides a non-contact surface treatment device for building facades, comprising a building facade working platform as described above and a spraying mechanism configured as the working unit. During operation, the thrust generating mechanism generates a thrust acting on the sliding unit to keep the spraying mechanism at a preset spraying interval.

[0031] Compared with existing technologies, the building facade work platform provided by this invention can be equipped with different work units to achieve facade cleaning, coating, and spraying operations. Taking cleaning as an example, the work unit is constructed as a brush head. The positive pressure thrust generated by the thrust generating mechanism of the work platform, directed towards the surface to be cleaned, allows the brush head to contact the building facade at a preset pressure, thus completing the facade cleaning operation. The entire work platform uses the thrust generating mechanism to provide thrust for the brush head to contact the building facade. Compared with negative pressure adsorption, this reduces the flatness requirements of the surface to be cleaned and makes it easier to adjust the pressure to achieve maximum treatment of stubborn stains. Of course, this positive pressure maintenance method also prevents accidental pressure loss and detachment that can occur with negative pressure adsorption. Furthermore, in this invention, the brush head can be easily switched from a first state of contact with the work surface to a second state of distance from the work surface through vector control of the thrust. For other applications, the work units can be changed to achieve polyurethane spraying or paint painting of the exterior wall insulation layer. Attached Figure Description

Detailed Implementation

[0043] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] These and other features of the invention will become apparent from the following description of preferred forms of embodiments given as non-limiting examples, with reference to the accompanying drawings.

[0045] It should also be understood that although the invention has been described with reference to some specific examples, those skilled in the art can certainly implement many other equivalent forms of the invention, which have the features described in the claims and are therefore all within the scope of protection defined herein.

[0046] The above and other aspects, features and advantages of the invention will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description. Example 1

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an embodiment of the present invention provides a building facade work platform that can be equipped with different work units to achieve facade work. In this embodiment, taking cleaning as an example, the positive pressure thrust generated by the thrust generating mechanism of the work platform towards the surface to be cleaned can cause the brush head to contact the building facade at a preset pressure, thereby achieving the cleaning of the building facade, which has a surface 100 to be treated. The work platform specifically includes: The traction rope 4 has one end connected to a high point on the building to form a mounting end (not shown in the figure); this mounting end can actually be a cantilever support or a similar structure located at the top of the building. For example, the lengths of the two traction ropes can be controlled by a winch deployed at the top of the building, thereby controlling the position of the traction suspension platform within the work area. In this method, the number of traction ropes 4 can be set according to the actual working environment. In most applications, preferably, two traction ropes 4 can be provided, and the traction ends of the two traction ropes 4 can be directly connected to the platform body. Of course, the work unit can also be connected through a separately designed traction suspension platform. At the same time, it is also understood that fixed anchor points located at the top of the building or at any high point of the building relative to the working plane can also be used to deploy traction ropes, as long as the fixed anchor points can at least define the boundary of the working plane or are at least located on both sides close to the boundary of the working plane. However, in this scheme, a rope-climbing device needs to be constructed on the traction suspension platform. This device controls the length of the two traction ropes. The other end of each traction rope can be a free end, passing through the rope-climbing device. The relative displacement of the rope-climbing device on the ropes controls the effective length of the traction ropes on both sides, thus achieving a change in position. Those skilled in the art will also understand that the larger the area defined by the traction ropes, the larger the working range of a single deployment. Therefore, preferably, whether the working position is controlled by a winch on the building roof, by the rope-climbing device on the traction suspension platform, or by a combination of both, the mounting ends of the two traction ropes 4 can be set with a reasonably large span. This is reflected in the traction ropes 4 themselves, meaning that the two traction ropes in the working state are roughly V-shaped and tensioned, achieving a relatively ideal working range.

[0048] Continue to refer to the appendix Figure 1 and attached Figure 2As shown, in this invention, the working part is actually connected to the platform body, which is suspended from the traction rope 4. The platform body includes a main structural member 1 and an actuating mechanism mounted on the main structural member 1. The actuating mechanism includes a thrust generating mechanism 6 and a sliding unit. The sliding unit is configured to connect to the working part used for exterior facade work, and under the action of the thrust generating mechanism, it has a first degree of freedom of movement relative to the main structural member 1 in a direction toward / away from the building facade. Specifically, the main structural member 1 includes a main column 101, on which a slide table 105 is mounted. The sliding unit is a slide rail assembly 8 mounted on the slide table 105. The slide rail assembly 8 slides on the slide table 105 under drive to achieve the first degree of freedom of movement. Taking exterior facade cleaning as an example, when the thrust generating mechanism 6 generates a thrust toward the surface 100 to be treated, the relative sliding of the slide rail assembly 8 on the slide table 105 allows the cleaning head to be held on the working surface with a certain force, achieving roller brush cleaning. When cleaning is completed within the area or when it is necessary to avoid obstacles, the holding force of the cleaning head can be released by reducing the thrust or generating a reverse force, thereby changing the working position. In some embodiments, the slide table 105 can also be configured to slide along the main column 101. In this case, lifting slide rails are provided on both sides of the main column 101, and the slide table is slidably mounted on the lifting slide rails to give it a second degree of freedom of movement in the second direction, which is perpendicular to the first direction. This second degree of freedom of movement means that while the thrust generating mechanism 6 continuously generates positive pressure to keep the cleaning workpiece in working condition, the slide table 105 itself can drive the sliding unit and the workpiece to move up and down as a whole, thereby achieving more efficient roller brush cleaning. In addition, to ensure that the slide rail assembly 8 moves within a preset stroke range, the slide rail assembly 8 is also provided with a limiting post 81 to limit the stroke range of the first degree of freedom of movement.

[0049] Specifically, in the above scheme, the slide table 105 includes a slide table base 1051 and a slider 1052 connected to the slide table base 1051. A groove (not labeled) is provided on the opposite outer side of the slider 1052. Two corresponding slide rail assemblies 8 are provided and slidably disposed within the grooves. In this structure, when the thrust generating mechanism 6 operates, it generates a positive pressure thrust acting on the slide rail assembly 8. The specific structure of the thrust generating mechanism 6 can optionally employ a motor-driven screw and nut mechanism, a gear and rack structure, or a crank-slider mechanism, etc. However, preferably, in this embodiment, the thrust generating mechanism 6 includes a ducted fan and a controller 7 for controlling the ducted fan. The sliding unit is connected to the ducted fan, and the controller 7 is electrically connected to an electrical box 16. The power supply components or power lines or signal lines extending from the main control board in the electrical box 16 can all be arranged inside the cable chain 9. The cable chain 9 is designed to orderly unwind and wind as the slide table 105 moves up and down, thereby guiding and protecting the internal cables and preventing them from tangling, wearing, or breaking under stress during frequent reciprocating motion, ensuring continuous and stable electrical transmission. As a further preferred embodiment, at least two ducted fans are provided, and the two ducted fans are controlled by the controller 7 to generate independently controllable thrust. Figures 1 to 4As shown, in some applications, the two ducted fans specifically include a first ducted fan 6001 and a second ducted fan 6002 arranged horizontally side by side. The first ducted fan 6001 and the second ducted fan 6002 are respectively connected to the two output shafts of the dual-output servo motor 62 via rotating brackets 61 to synchronously adjust the thrust direction. In this invention, the main function of the thrust generating mechanism 6 is to maintain a stable distance or stable contact between the working part and the surface to be treated during the operation. Especially in contact operations, a certain preset downward pressure is often required, which requires the first ducted fan 6001 and the second ducted fan 6002 to generate a continuous positive thrust toward the building facade. It is foreseeable that during the operation, due to the presence of positive thrust, a certain frictional force will be generated between the working part and the wall surface. This frictional force may generate a tilting moment, especially when treating rough exterior surfaces, the tilting moment received by the entire working platform may be more significant. Therefore, in this embodiment, by driving the rotating bracket 61 with the dual-output servo motor 62, the thrust direction of the first ducted fan 6001 and the second ducted fan 6002 can be dynamically adjusted. By adjusting the direction of the positive thrust, a torque opposite to the tilting torque can be generated, making the overall operation of the work platform more stable. In addition, during operation, it is foreseeable that the building facade is not an ideally flat surface and may encounter obstacles. If special work path planning is performed for obstacles, it may lead to a decrease in work efficiency. Therefore, in this embodiment, it is also possible to consider changing the thrust direction of the first ducted fan 6001 and the second ducted fan 6002, such as... Figure 5 and Figure 6 As shown, the positive thrust becomes a reverse thrust that moves the work platform away from the surface to be treated 100. When the work platform is completely away from the surface to be treated, it can complete a limited obstacle crossing operation to a certain extent and achieve relatively continuous operation.

[0050] Based on the same considerations mentioned above, in other applications of the present invention, an auxiliary thrust unit can also be added. This auxiliary thrust unit can be located between the first ducted fan 6001 and the second ducted fan 6002, and the auxiliary thrust unit is configured to controllably generate a force with a direction different from the thrust of the first ducted fan 6001 and the second ducted fan 6002. Unlike the technical solution that only adjusts the thrust direction of the first ducted fan 6001 and the second ducted fan 6002, in this solution, the first and second ducted fans are mainly used to maintain the preset downforce during operation. The auxiliary thrust unit then provides the counter-thrust required to balance the tilting moment and overcome obstacles. Specifically, as... Figure 7In one specific structure, the auxiliary thrust unit includes a third ducted fan 601 electrically connected to the controller 7. The third ducted fan 601 is attitude-adjustably connected to the outside of the controller 7 via a tilt joint 603, thereby adjusting its thrust direction. The tilt joint 603 includes at least one tilt joint servo 6031. When the tilt joint servo 6031 is working, it can control the third ducted fan 601 to generate a first auxiliary thrust opposite to the thrust direction of the horizontally positioned first ducted fan 6001 and second ducted fan 6002, and to generate a second auxiliary thrust at an angle to the thrust directions of the first ducted fan 6001 and second ducted fan 6002. The first and second auxiliary thrusts can specifically refer to the thrust used to balance the tilting moment and the reverse thrust used to assist the work platform in overcoming obstacles; generally, they are... Figure 7 The reverse thrust shown and Figure 8 The vertical thrust is shown. But specifically, Figure 8 The thrust shown is used to balance the tilting moment. The magnitude and direction of the thrust can be dynamically adjusted according to the friction generated by the actual surface working conditions and the attitude of the working platform.

[0051] As a response Figure 7 and Figure 8 In one variation of the implementation, in some applications, the surface conditions are relatively good and stable, and fine adjustment of the auxiliary thrust unit is not required. Therefore, as a preferred option, such as... Figure 9 As shown, the third ducted fan 601 can be fixedly connected to the outside of the controller 7 and the thrust direction it generates is opposite to the thrust direction of the first ducted fan 6001 and the second ducted fan 6002; it also includes a fourth ducted fan 602, which is electrically connected to the controller 7 and is fixedly connected to the outside of the controller, and the thrust direction it generates is perpendicular to the thrust direction of the first ducted fan 6001 and the second ducted fan 6002.

[0052] When realizing the movement of the slide 105 on the main structural member 1, for example, as follows: Figure 2 , Figure 3 and Figure 4As shown, the main column 101 has a drive wheel mechanism 103 at its top and a driven wheel mechanism 104 at its bottom. The drive wheel mechanism 103 and the driven wheel mechanism 104 are connected by a belt 102, and the slide 105 is connected to the belt 102. In addition, to facilitate remote monitoring of the work status by operators, a camera 3 for video acquisition is mounted on the outside of the drive wheel mechanism 104 via a camera bracket 31. The camera bracket 31 also has protective wheels 32. The protective wheels 32 and the elastic rubber wheels 121 of the caster assembly, in addition to providing a certain rolling displacement effect, both serve to prevent hard impacts on the facade, especially on glass curtain walls or windows.

[0053] In the above-described technical solution of the building facade operation platform of the present invention, Figures 1 to 4 The technical solutions provided in the examples can all further include a traction suspension platform 5, such as... Figure 3 and Figure 4 As shown, the function of the traction suspension platform 5 is to form a work platform with a variable position within the working area under the traction action of the traction rope 4. Preferably, the traction suspension platform 5 includes at least a rope pulley assembly with two traction ropes 4 wound around them respectively. In this embodiment, there are two rope pulley assemblies, namely rope pulley assembly 53 and rope pulley assembly 54, which are symmetrically arranged on the base plate 52. Each rope pulley assembly also includes a rope pulley cover to prevent the traction rope 4 from slipping off; as shown in the figure, rope pulley cover 531 and rope pulley cover 541. Each rope pulley assembly also includes at least a friction wheel (not shown in the figure) and a reduction motor 51 that drives the friction wheel. When the reduction motor 51 is working, the rotational torque of the friction wheel will generate the traction force of the traction rope 4 under the action of friction. During this process, the rope length of the traction ropes 4 on both sides can be precisely changed, thereby realizing the position change of the entire traction suspension platform 5 in the working plane. At the same time, the suspension node formed at the bottom of the base plate 52 can realize the overall suspension and fixation of the working part. Continue to refer to Figure 1As shown, in this invention, during actual operation, when the thrust generating mechanism 6 acts on the working part, as described above, the contact between the working part and the surface 100 to be processed may generate a resistance torque. To balance this torque, in the above-described solution of this invention, the tilting torque can be balanced by controlling the thrust direction through the ducted fan in the thrust generating mechanism. However, as a supplement to this method, it is also possible to consider adding a lifting point adjustment assembly 17 to generate a certain tilting torque to offset it. Specifically, the electrical box 16 is provided with a lifting point adjustment assembly 17 connected to the main column 101. The lifting point adjustment assembly 17 is connected to the suspension node formed at the bottom of the base plate 52 and is configured to adjust the offset of the suspension node relative to the center of gravity of the working platform, thereby providing an initial torque for the working platform to offset the tilting torque. More specifically, as shown in the figure, the lifting point adjustment assembly 17 includes a lifting point adjustment motor (not labeled), a lifting point adjustment screw 55 connected to the output shaft of the lifting point adjustment motor, and a screw nut 56 connected to the lifting point adjustment screw 55 on the suspension node. When the lifting point adjustment motor is working, the screw nut 56 connected to the suspension node will be displaced, causing the center of gravity of the suspension node to shift relative to the working platform. Example 2

[0054] In this embodiment, a contact surface treatment device for building facades is also provided. This contact surface treatment includes, but is not limited to, cleaning, applying decorative coatings, and detecting hollow areas. In such applications, the working unit can be replaced with a corresponding working device. For example, in this embodiment, based on the building facade working platform provided in Embodiment 1, the working unit can be specifically constructed as a brush head. During operation, the thrust generating mechanism 6 generates a thrust acting on the sliding unit to make the brush head contact the building facade with a preset pressure. The brush head includes at least a brush head frame and a brush head body disposed on the brush head frame. When performing contact cleaning operations, it is often necessary to spray water or cleaning fluid while brushing the surface to be treated 100. Therefore, in some improved solutions, the brush head further includes a liquid distribution mechanism for providing the liquid during contact surface treatment. Figure 4As shown, the liquid distribution mechanism includes a material tank 10 and a spray head connected to the material tank 10 via a liquid pipe. The spray head is configured to spray material onto the exterior facade of the building. The material tank 10 can actually be deployed on the top of the building or on a working platform on the exterior facade. In this case, a lower sealing plate 107 of the material tank is provided on the side of the main column 101 near the driven wheel mechanism 104. The material tank 10 is mounted on the lower sealing plate 107 and fixedly connected to the main column 101. An adjustable foot 106 is provided at the bottom of the lower sealing plate 107. A caster bracket 122 is provided on the outer side of the driven wheel mechanism 104 corresponding to the position of the adjustable foot 106. A caster assembly 12 is provided on the caster bracket 122. To describe it more specifically, the top of the material bin 10 is provided with a material bin upper sealing plate 108, and the material bin upper sealing plate 108 is provided with a water pump 2 and a water outlet 1001; the material bin upper sealing plate 108 is connected to the main column 101 through a first mounting plate 57. Similar to the material bin 10, the electrical box 16 can be deployed at a remote location and communicate with the controller 7 via wired or wireless means, or it can be installed as a whole on the building facade working platform. In this case, the bottom of the electrical box 16 is connected to the main column 101 through the first mounting plate 57, and its top is connected to the main column 101 through a second mounting plate 58.

[0055] In this embodiment, to achieve better cleaning results, the brush head is preferably constructed as a roller brush assembly, such as... Figure 2 The roller brush assembly includes a spindle 145 and a brush body 141 covering the spindle 145. The spindle 145 is a hollow structure with seepage holes on its outer periphery to facilitate the seepage of liquid and an inlet connector 143 for conveying liquid into the spindle 145. The inlet connector 143 and the spindle 145 together form the spray head. In this structure, there is no need to set a separate water replenishment nozzle; the brush body 141 is evenly moistened only through the seepage holes on the spindle. Of course, if it is necessary to add cleaning agents for cleaning glass, they can be added directly to the material tank without the need for a separate pipeline for replenishing the cleaning agents. Furthermore, for the brush body 141 itself, a material with excellent water absorption and retention properties can be selected, such as polyvinyl alcohol foam (PVA), polyurethane foam, etc., or preferably made of composite flexible absorbent materials. For example, the brush body 14 itself comprises an inner layer and an outer layer. The inner layer, wrapped around the outer periphery of the mandrel 145, is made of a highly porous polyurethane sponge with superior water absorption, used for buffering and uniformly guiding the cleaning fluid. The outer layer is a removable microfiber cloth cover, or a blend of microfiber and nylon filaments with terminal flowering treatment. This material combination ensures both physical scrubbing ability against stubborn stains and good hydrophilicity and non-destructive contact with the glass surface.

[0056] To improve the cleaning effect of the brush head during operation, the brush head also includes a rotation adjustment mechanism 15. The rotation adjustment mechanism 15 includes a torsion motor (not labeled) connected to the sliding unit. The output end of the torsion motor 151 is connected to a swing arm 152 that can swing controllably within a predetermined angle range. The spindle 145 is connected to the swing arm 152 via a brush head rod holder 142. A swing arm connector 144 is connected to the swing arm 152, and the brush head rod holder 142 is connected to the swing arm 152 connector 144. A scraper 13 parallel to the brush body is also provided on the swing arm connector 144. When the swing arm swings, the brush head can enter a first state where the brush head contacts the surface to be treated, or a second state where the scraper contacts the surface to be treated. In other words, during the cleaning process, the surface to be treated 100 can be brushed by the roller brush assembly 14, and then the swing angle can be adjusted by rotating the adjustment mechanism 15 to release the scraper 13 from the surface to be treated 100, remove excess water and complete the cleaning operation, and avoid water stains.

[0057] Unlike Embodiment 2, in this embodiment, the surface treatment of the building facade mainly focuses on non-contact surface treatment, such as spraying polyurethane insulation or decorative coatings. The non-contact surface treatment device for building facades provided in this application, such as... Figure 10 As shown, the system includes a building facade work platform as described above and a spraying mechanism configured as the work unit. During operation, the thrust generating mechanism 6 generates a thrust acting on the sliding unit to maintain the spraying mechanism at a preset spraying interval. The spraying mechanism includes at least a main mounting frame and nozzles 162 connected to the main mounting frame. The nozzles 162 are connected to a paint tank (not shown) via a high-pressure material pipe 163. Specifically, the main mounting frame includes a connecting hinge 160 connected to the sliding unit and a crossbeam 161 fixed to the connecting hinge 160. The nozzles 162 may be flat nozzles and multiple nozzles are provided. Figure 10The diagram shows two flat nozzles spaced at an appropriate interval on the crossarm 161, creating two fan-shaped spray surfaces 167 for more uniform spraying. As a further improvement, the crossarm 161 has adjustable support rods 166 extending towards the surface 100 to be treated, and adjusting nuts 165 for fixing the support rods 166. A second elastic rubber wheel 164, rollingly contacting the surface 100, is located on the side of the support rod 166 closest to it. The support rods 166 and adjusting nuts 165 allow for pre-setting the spraying distance according to the spraying process requirements, while the second elastic rubber wheel 164 ensures flexible contact with the surface during operation, preventing damage to the facade and maintaining the stability of the work platform. The spray tank provides premixed materials and may have multiple chambers capable of holding various materials. In this case, the nozzle can be designed with multiple mixing chambers, allowing the materials to be mixed or further atomized within the nozzles during operation, thus completing the spraying process.
