Description

Technical Field

[0001] This invention relates to an environmentally friendly building exterior decoration construction equipment, specifically to a technology that can automatically complete the painting of building exterior walls and windows. Background Technology

[0002] Typically, after a high-rise building is completed, its exterior walls need to be decorated, such as by spraying anti-stone paint or real stone paint. Before spraying the anti-stone paint or real stone paint, a layer of transparent primer needs to be applied to the exterior wall. The transparent primer mainly serves to penetrate, resist alkali, and seal, allowing the anti-stone paint or real stone paint to adhere more firmly to the exterior wall. There are usually windows on the exterior walls of buildings, i.e., the pre-installed windows. The outer edge of the middle section of the window also needs to be primed. The middle section of the window is for window installation, while the inner edge of the middle section belongs to the building's interior. Figure 1 As shown, there is an existing building exterior wall 1 with multiple windows 2 in the middle of the exterior wall. When applying the primer, the exterior wall and the outer ends of the middle of the windows 2 need to be coated with primer.

[0003] Currently, when applying primer to exterior walls and windows, it is mainly done manually by holding a paint roller. However, manual painting is very laborious and poses occupational hazards to the human body, so it is not an environmentally friendly construction method. Summary of the Invention

[0004] To address the problems existing in the above-mentioned technologies, the present invention provides an environmentally friendly technology that automates the painting of exterior walls and windows and achieves better painting results.

[0005] This invention provides an environmentally friendly building exterior decoration construction equipment, comprising a lateral moving component, a rotating component, a telescopic component, a painting component, and a feeding component;

[0006] The lateral moving component is located at the front end of the suspended basket, the rotating component is located on the lateral moving component, the telescopic component is connected to the rotating component, and the painting component is connected to the telescopic component. The lateral moving component is used to drive the rotating component, the telescopic component, and the painting component to move laterally. The rotating component is used to drive the telescopic component and the painting component to rotate. The telescopic component is used to drive the painting component to move forward or backward. The painting component has a hollow shaft, a rotating roller is provided on the hollow shaft, a brush body layer is provided on the rotating roller, multiple holes are provided on the hollow shaft, and multiple drainage holes are provided on the rotating roller. The feeding component is located inside the suspended basket. The feeding component includes a storage tank and a connecting hose. One end of the connecting hose is connected to the storage tank through a suction pump. An extension pipe is provided on the outer side of the upper end of the hollow shaft, and the extension pipe is detachably connected to the other end of the connecting hose.

[0007] The aforementioned beneficial effects are as follows: The hoist moves the suspended platform along the exterior wall. Personnel connect the connecting hose and extension pipe. A suction pump draws primer from the storage tank through the connecting hose and extension pipe into the hollow shaft, then through holes into the rotating roller, and finally through the drain hole into the brush layer. The lateral movement of the lateral moving component causes the rotating roller to rotate along the exterior wall, completing the painting of the exterior wall. The telescopic component increases the contact force between the brush layer and the exterior wall, allowing the primer to penetrate the wall better. When painting windows, the rotating component drives the painting assembly to rotate, moving it to a horizontal or vertical position. The telescopic component then moves the painting assembly back and forth. Combined with the lateral movement of the lateral moving component and the vertical movement of the suspended platform, the horizontal and vertical painting of windows can be completed. This automated process for painting exterior walls and windows results in a better painting effect.

[0008] The use of such automated equipment reduces human contact with coatings, avoids occupational hazards, and achieves more environmentally friendly and healthier requirements.

[0009] In a preferred embodiment, the lateral moving component includes a lead screw, a slide bar, and a moving part, with the two ends of the lead screw and the slide bar respectively disposed on vertical blocks on the upper sides of both ends of the suspended basket, and the moving part disposed on the lead screw and the slide bar.

[0010] In a preferred embodiment, the rotating component includes a horizontal plate, a rotating shaft, and a drive motor. The horizontal plate is disposed at the upper end of the vertical moving part, the rotating shaft is disposed at the front end of the horizontal plate, and the drive motor is connected to the rotating shaft.

[0011] The telescopic assembly includes a U-shaped frame, a movable plate, a rotating cam, a rotating shaft, a drive wheel, a rotary motor, a fixed rod, and a return spring. The vertical block of the U-shaped frame is connected to the rotating shaft. The rotating shaft is located between the two horizontal blocks of the U-shaped frame. The rotating cam is mounted on the rotating shaft. The fixed rod is located at the front end of each of the two horizontal blocks. The movable plate is mounted on each of the two fixed rods. The inner ends of the two horizontal blocks and the two movable plates are connected by the return spring. A plate structure is located between the two movable plates. The drive wheel is located at the front end of the plate structure. The drive wheel cooperates with the rotating cam. The rotary motor is connected to one end of the rotating shaft. A hollow shaft is located between the front ends of the two movable plates. A rotating roller is mounted on the hollow shaft. A brush layer made of wool is provided on the rotating roller.

[0012] A preferred embodiment further includes a filling assembly comprising a brush and a telescopic cylinder. One side of the movable plate is provided with a guide groove. The brush comprises a frame and bristles. The frame is movably disposed within the guide groove, and multiple outlet holes are provided on the outer end of the frame. The bristles are disposed on the outer end of the frame. The rear end of the frame is connected to the telescopic rod of the telescopic cylinder. The end of the telescopic cylinder is connected to a cross block. The upper end of the frame is connected to one end of a first flexible hose. The other end of the first flexible hose and one end of an extension tube are respectively connected to a three-way valve. A feed pipe is provided in the middle of the three-way valve.

[0013] The working method of the environmentally friendly building exterior decoration construction equipment provided by this invention includes the following steps:

[0014] The hoist moves the suspended platform along the building's exterior wall, bringing the paint layer into contact with the wall. A connecting hose and extension pipe connect, and a suction pump draws primer from the storage tank through the connecting hose and extension pipe into the hollow shaft. The primer then enters the rotating roller through holes and leaks into the paint layer. Through the action of the lateral moving parts, the rotating roller drives the paint layer to rotate, applying paint to the exterior wall. A telescopic component moves the paint assembly towards the exterior wall, increasing the contact force between the paint layer and the wall, allowing the primer to penetrate more easily. When windows need painting, the rotating part drives the paint assembly to rotate, positioning it horizontally or vertically. The telescopic component then moves the paint assembly back and forth, and the lateral moving parts and the suspended platform move horizontally and vertically, completing the horizontal and vertical painting of windows. This automated process for painting building exterior walls and windows yields better results.

[0015] The working method of the environmentally friendly building exterior decoration construction equipment provided by this invention includes the following steps:

[0016] The motor drives the lead screw to rotate, causing the moving part to move laterally along the slide bar. The movement of the moving part drives the rotating part, the telescopic component, and the painting component to move laterally. The lateral movement of the painting component causes the rotating roller to drive the brush body layer to rotate along the outer wall and paint the outer wall, thus realizing an automated painting process.

[0017] The working method of the environmentally friendly building exterior decoration construction equipment provided by this invention includes the following steps:

[0018] A drive motor rotates a rotating shaft, which in turn rotates a U-shaped frame. The U-shaped frame then rotates the painting assembly to either a horizontal or vertical position. When the painting assembly is vertical, the feeding assembly continuously feeds primer onto the brush body layer. At this point, a lateral moving component moves the painting assembly laterally, and the rotating roller rotates the brush body layer, continuously applying the primer onto the exterior wall. Alternatively, a rotary motor can drive a rotating shaft, which in turn rotates a rotating cam. The rotating cam, through a drive wheel, moves two moving plates forward, which in turn move the rotating roller forward, eventually stopping the rotating cam at a designated position. Positioning increases the contact force between the brush layer on the rotating roller and the exterior wall, allowing the primer to penetrate the wall better. When the painting assembly is in a vertical position, the telescopic component drives the painting assembly to move back and forth continuously. Then, the up and down movement of the basket allows the brush layer on the rotating roller to complete the vertical painting of the window. When the painting assembly is in a horizontal position, the telescopic component drives the painting assembly to move back and forth, and then the lateral movement of the lateral moving component allows the brush layer on the rotating roller to complete the lateral painting of the window. In this way, both the exterior wall and the window can be painted.

[0019] The working method of the environmentally friendly building exterior decoration construction equipment provided by the present invention includes the following steps:

[0020] To achieve a better painting effect on the window, after the brush body layer on the rotating roller completes the painting, the telescopic cylinder extends, causing the brush to move forward along the guide groove and enter the window. At this point, the rotating roller is outside the window. Simultaneously, the connecting hose connects to the feed pipe, and then, through the action of the three-way valve, the primer in the storage tank is drawn into the frame through the connecting hose, feed pipe, and first hose via the suction pump. It then flows from the outlet onto the brush bristles and, in conjunction with the rotating component, causes the brush to rotate, bringing the bristles into contact with the corners of the window in the horizontal and vertical directions. The telescopic cylinder then contracts and extends to complete the painting of the corners inside the window. Subsequently, the painting of the four corners of the window is carried out in sequence. By controlling the three-way valve, the paint can be fed onto the brush or painting assembly. Attached Figure Description

[0028] First embodiment:

[0029] like Figures 2 to 4 As shown, the present invention provides an environmentally friendly building exterior decoration construction equipment, including a lateral moving part 10, a rotating part 20, a telescopic component 30, a painting component 40, and a feeding component 50;

[0030] The lateral moving member 10 is disposed at the front end of the suspended basket 5, the rotating member 20 is disposed on the lateral moving member 10, the telescopic assembly 30 is connected to the rotating member 20, and the painting assembly 40 is connected to the telescopic assembly 30. The lateral moving member 10 is used to drive the rotating member 20, the telescopic assembly 30, and the painting assembly 40 to move laterally. The rotating member 20 is used to drive the telescopic assembly 30 and the painting assembly 40 to rotate. The telescopic assembly 30 is used to drive the painting assembly 40 to move forward or backward. The painting assembly 40 has a hollow shaft 41. The hollow shaft 41 is provided with a rotating roller 42, the rotating roller 42 is provided with a brush layer 43, the hollow shaft 41 is provided with a plurality of holes 44, the rotating roller 42 is provided with a plurality of drainage holes 45, the feeding assembly 50 is provided inside the basket 10, the feeding assembly 50 includes a storage tank 51 and a connecting hose 52, one end of the connecting hose 52 is connected to the storage tank 51 through a suction pump, and an extension tube 53 is provided on the outer side of the upper end of the hollow shaft 41, the extension tube 53 is detachably connected to the other end of the connecting hose 52.

[0031] The hoist moves the suspended platform 5 along the building's exterior wall, bringing the paint layer 43 into contact with the wall. The connecting hose 52 connects to the extension pipe 53. A suction pump draws primer from the storage tank 51 through the connecting hose 52 and extension pipe 53 into the hollow shaft 41, then through the hole 44 into the rotating roller 42, and finally through the drain hole 45 into the paint layer 43. The lateral moving component 10 causes the rotating roller 42 to rotate, thus painting the exterior wall. The telescopic component 30 moves the painting assembly 40 towards the exterior wall. This increases the contact force between the brush layer 43 and the exterior wall, making it easier for the primer to penetrate into the wall. When it is time to paint window 2, the rotating component 20 drives the painting component 40 to rotate, so that the painting component 40 is rotated to a horizontal or vertical position. Then, the telescopic component 30 drives the painting component 40 to move back and forth. Then, through the lateral movement of the lateral moving component 10 and the up and down movement of the hanging basket 5, the painting of window 2 in the horizontal and vertical directions can be completed. The painting of the building exterior wall 1 and window 2 can be completed automatically, and the painting effect is better.

[0032] In addition, the use of such automated equipment reduces personnel's contact with coatings, avoids occupational hazards, and achieves more environmentally friendly and healthier requirements.

[0033] Second embodiment:

[0034] like Figure 2 and Figure 5 As shown, the lateral moving part 10 includes a lead screw 11, a slide bar 12 and a moving part 110. The two ends of the lead screw 11 and the slide bar 12 are respectively disposed on the vertical blocks 13 on the upper side of the two ends of the basket 10, and the moving part 110 is disposed on the lead screw 11 and the slide bar 12.

[0035] The motor drives the lead screw 11 to rotate, causing the moving part 110 to move laterally along the slide bar. The movement of the moving part 110 drives the rotating part 20, the telescopic component 30 and the painting component 40 to move laterally. The lateral movement of the painting component 40 causes the rotating roller 42 to drive the brush layer 43 to rotate along the outer wall and paint the outer wall, thus realizing an automated painting process.

[0036] Third embodiment:

[0037] like Figure 5 As shown, the rotating component 20 includes a horizontal plate 21, a rotating shaft 22, and a drive motor 23. The horizontal plate 21 is disposed at the upper end of the two moving parts 110, the rotating shaft 22 is disposed at the front end of the horizontal plate 21, and the drive motor 23 is connected to the rotating shaft 22.

[0038] The telescopic assembly 30 includes a U-shaped frame 31, a movable plate 32, a rotating cam 33, a rotating shaft 34, a drive wheel 35, a rotary motor 36, a fixed rod 37, and a return spring 38. The vertical block 71 of the U-shaped frame 31 is connected to the rotating shaft 22. The rotating shaft 34 is disposed between the two horizontal blocks 72 of the U-shaped frame 31. The rotating cam 33 is disposed on the rotating shaft 34. The fixed rod 37 is disposed at the front end of each of the two horizontal blocks 72. The movable plate 32 is disposed on each of the two fixed rods 37. The horizontal block 72 and the inner ends of the two movable plates 32 are respectively connected by the return spring 38. A plate structure 73 is provided between the two movable plates 32. The front end of the plate structure 73 is provided with the drive wheel 35. The drive wheel 35 cooperates with the rotating cam 33. The rotary motor 36 is connected to one end of the rotating shaft 34. The hollow shaft 41 is provided between the front ends of the two movable plates 32. The rotating roller 42 is provided on the hollow shaft 41. The rotating roller 42 is provided with a brush layer 43, which is made of wool.

[0039] The drive motor 23 drives the rotating shaft 22 to rotate, which in turn drives the U-shaped frame 31 to rotate. The U-shaped frame 31 drives the painting assembly 40 to rotate to a horizontal or vertical position. When the painting assembly 40 is vertical, the feeding assembly 50 continuously feeds primer onto the brush body layer 43. At this time, the lateral moving part 10 drives the painting assembly 40 to move laterally, and the rotating roller 42 drives the brush body layer 43 to rotate, so that the primer on the brush body layer 43 is continuously painted onto the exterior wall. The rotating motor 36 drives the rotating shaft 34 to rotate, which in turn drives the rotating cam 33 to rotate. The rotating cam 33 drives the two moving plates 32 to move forward through the drive wheel 35. The two moving plates 32 drive the rotating roller 42 to move forward, and then the rotating cam... When the roller 33 stops at the corresponding position, the contact force between the brush layer 43 on the rotating roller 42 and the exterior wall increases, allowing the primer to penetrate the wall better. When the painting assembly 40 is in a vertical position, the telescopic assembly 30 drives the painting assembly 40 to move back and forth continuously. Then, the vertical movement of the basket 10 causes the brush layer 43 on the rotating roller 42 to complete the vertical painting of the window 2. When the painting assembly 40 is in a horizontal position, the telescopic assembly 30 drives the painting assembly 40 to move back and forth. Then, the horizontal movement of the lateral moving part 10 causes the brush layer 43 on the rotating roller 42 to complete the horizontal painting of the window 2. In this way, both the exterior wall and the window 2 can be painted.

[0040] Additionally, when the U-shaped frame rotates, the connecting hose and extension tube can be disassembled. Then, when the U-shaped frame rotates to the corresponding position, the connecting hose and extension tube can be reconnected.

[0041] Fourth embodiment:

[0042] like Figure 6 and Figure 7 As shown, it also includes a filling component 80, which includes a brush 81 and a telescopic cylinder 82. One of the movable plates 32 has a guide groove 83 on one side. The brush 81 includes a frame 84 and bristles 85. The frame 84 is movably disposed in the guide groove 83. The outer end of the frame 84 is provided with multiple outlet holes 86. The bristles 85 are disposed on the outer end of the frame 81. The rear end of the frame 81 is connected to the telescopic rod of the telescopic cylinder 82. The end of the telescopic cylinder 82 is connected to the cross block 72. The upper end of the frame 81 is connected to one end of the first hose 87. The other end of the first hose 87 and one end of the extension tube 53 are respectively connected to a three-way valve 88. The middle of the three-way valve 88 is provided with a feed pipe 89.

[0043] To improve the painting effect of window 2, after the brush body layer 43 on the rotating roller 42 has finished painting window 2, the telescopic cylinder 82 extends, causing the board brush 81 to move forward along the guide groove 83 and enter the window 2. At this time, the rotating roller 42 is outside the window 2. Simultaneously, the connecting hose 52 is connected to the feed pipe 89. Then, through the action of the three-way valve 88, the primer in the storage tank 51 is pumped through the connecting hose 52, feed pipe 89, and the feed pipe 89. A flexible tube 87 enters the frame 84 and flows from the outlet 86 to the bristles 85, cooperating with the rotating part 20 to rotate the brush 81, so that the bristles 85 contact the corner 3 between the horizontal and vertical directions of the window 2. Then, the telescopic cylinder 82 retracts and extends to complete the painting of the corner 3 inside the window 2. After that, the painting of the four corners 3 of the window 2 is carried out in sequence. By controlling the three-way valve 88, the material can be fed to the brush 81 or the painting assembly 40.

[0044] like Figure 1 As shown, the front end of the suspended platform 5 is provided with two support wheels 6.

[0045] It should be noted that when rotating the U-shaped frame, the connecting hose does not need to be disassembled. You only need to hold the connecting hose manually. That is, the rotation of the U-shaped frame will not affect the placement of the connecting hose. Since the rotation angle of the U-shaped frame is usually 90 degrees, it will not have any impact.

[0046] Furthermore, the rotation of the U-shaped frame can create a rotary friction brushing effect. Although under normal circumstances, the U-shaped frame is fixed at a certain angle after being rotated to a certain angle, it can also be kept rotating during brushing to form a rotary brushing effect. In this case, the paint assembly 40 can be kept precise. The rotation of the U-shaped frame drives the paint assembly 40 to rotate, thereby forming certain geometric patterns, such as semi-circular or circular structures. This allows for the creation of the desired patterns as needed, and can be used when specific geometric patterns are required on certain walls.

[0047] Because the painting components can rotate, they can be used to paint windows on horizontal or vertical walls, and can also be used to paint angled windows, with excellent results.
