Abstract
Description
Technical Field
[0001] This application relates to the field of exterior wall construction, and in particular to an exterior wall coating device and construction method. Background Technology
[0002] After applying putty to the exterior walls of a building, a layer of paint is usually applied on top of the putty. The paint enhances the aesthetics of the building's exterior.
[0003] When applying paint to exterior walls, a suspension system is typically installed on the top side of the building, and a suspended platform is connected to the suspension system via traction ropes. Workers then apply the paint to the exterior walls from the suspended platform.
[0004] If the suspended platform is damaged or the traction rope breaks while construction workers are on it, they may be trapped at a height or even fall directly from the height, which reduces the safety of construction workers when applying paint to the exterior wall. Summary of the Invention
[0005] To improve the safety of coating exterior walls, this application provides an exterior wall coating device and construction method.
[0006] This application provides an exterior wall coating device and construction method, which adopts the following technical solution:
[0007] An exterior wall coating device includes a body with lifting mechanisms installed on both sides. Each lifting mechanism is equipped with a traction rope, one end of which is connected to the top of a building. A first linear module is installed on the side of the body facing the building's exterior wall, and a second linear module is installed on the first linear module. The first linear module drives the second linear module to move horizontally. A sliding seat is installed on the second linear module, which drives the sliding seat to rise and fall. A painting roller is installed on the sliding seat. A storage bin is installed on the body, and a feeding mechanism is installed in the storage bin to deliver paint from the storage bin to the painting roller. Rollers are installed on the side of the body facing the building's exterior wall, and the body is pressed against the building's exterior wall via the rollers.
[0008] By adopting the above technical solution, construction workers suspend the machine body to the exterior wall of the building via traction ropes. The feeding mechanism then delivers paint from the storage bin to the painting roller. The second linear module, via a sliding seat, raises and lowers the painting roller, thus applying the paint to the building's exterior wall. After the second linear module moves the sliding seat from one end to the other, the first linear module moves the second linear module horizontally, facilitating the movement of the painting roller to the unpainted exterior wall. While the first linear module moves the second linear module from one end to the other, the machine body descends via a hoist and traction ropes, again facilitating the movement of the painting roller to the unpainted exterior wall. When the machine body moves from the top side to the bottom side of the building, the exterior wall painting is complete, thus reducing the need for workers to work at heights and improving the safety of exterior wall painting.
[0009] Optionally, a first connecting rod is installed at both ends of the paint roller. The first connecting rod rotates about the axis of the paint roller. The first connecting rod slides through the sliding seat. A spring and a support block are provided on the side of the sliding seat away from the paint roller. The spring is sleeved on the first connecting rod, and the support block abuts against the end of the first connecting rod away from the paint roller. The spring is installed between the support block and the sliding seat.
[0010] By adopting the above technical solution, when the machine body is pressed against the exterior wall of the building by the rollers, the paint roller moves towards the sliding seat under the pressure of the exterior wall. Then, the first connecting rod pushes the support block away from the sliding seat, thereby stretching the spring. After the spring is stretched, the spring force drives the paint roller to press firmly against the exterior wall of the building, thus facilitating the application of paint to the exterior wall. If the paint roller is damaged, the first connecting rod can be pulled out of the sliding seat, making it easy to remove the damaged paint roller from the sliding seat for replacement.
[0011] Optionally, a first pressure block is fixedly installed on both sides of the top of the second linear module. The bottom side of the first pressure block is gradually raised from the side near the sliding seat to the other side and is inclined. A second pressure block is fixedly installed on both sides of the bottom of the second linear module. The top side of the second pressure block is gradually lowered from the side near the sliding seat to the other side and is inclined.
[0012] By adopting the above technical solution, when the sliding seat moves to the top of the second linear module, the support block and the bottom side of the first pressure block are pressed together, causing the support block to move away from the sliding seat, thereby allowing the paint roller to lightly abut against the exterior wall. When the sliding seat moves to the bottom of the second linear module, the support block and the top side of the second pressure block are pressed together, causing the support block to move away from the sliding seat, thereby allowing the paint roller to lightly abut against the exterior wall. Because the paint roller lightly abuts against the exterior wall when the sliding seat is at the end of the second linear module, the occurrence of friction damage between the paint roller and the exterior wall when the first linear module drives the second linear module to move horizontally is reduced.
[0013] Optionally, the feeding mechanism includes a pump, a cover, a mounting base, nozzles, a feeding pipe, and a recovery pipe. The cover is detachably mounted on a sliding base, and the mounting base is detachably mounted on the top side of the cover. There are multiple nozzles, and each nozzle is fixedly mounted on the mounting base. The cover has an inlet and outlet on the side away from the sliding base. The inlet and outlet are used for the brush roller to enter and exit the cover. The nozzles are positioned facing the inlet and outlet. The pump body of the pump is fixedly mounted on a storage tank. The inlet end of the pump is connected to the storage tank. One end of the feeding pipe is connected to the outlet end of the pump, and the other end of the feeding pipe is connected to each nozzle. One end of the recovery pipe is connected to the bottom side of the cover, and the other end of the recovery pipe is connected to the top side of the storage tank. The bottom side of the cover is inclined, gradually rising from the location of the recovery pipe.
[0014] By adopting the above technical solution, a pump is activated when feeding paint to the paint roller. The pump extracts paint from the storage tank and then delivers it to each nozzle through a feed pipe. The nozzles then spray paint onto the paint roller, facilitating paint addition. A portion of the paint sprayed onto the paint roller falls into the inner bottom wall of the cover, where it is inclined to enter the recovery pipe. When the sliding seat moves to the top of the second linear module, the paint returns from the recovery pipe to the storage tank, facilitating paint recovery.
[0015] Optionally, the mounting base is located inside the cover, and the mounting base is provided with a second connecting rod. One end of the second connecting rod is rotatably inserted into the mounting base, and the other end of the second connecting rod slides through the top side of the cover. A limiting ring is threaded onto the second connecting rod, and the limiting ring is located outside the cover.
[0016] By adopting the above technical solution, the limiting ring is screwed into the second connecting rod and pressed tightly against the outer top wall of the cover, thereby facilitating the installation of the mounting base inside the cover.
[0017] Optionally, the sliding seat has a slot for inserting the cover body on the side near the paint roller, the sliding seat is provided with a pressure rod, and the periphery of the sliding seat has a threaded hole for the pressure rod to pass through, the threaded hole communicating with the slot.
[0018] By adopting the above technical solution, after the cover is inserted into the slot, the pressure rod is screwed into the screw, so that the pressure rod presses the part of the cover that enters the slot, thereby facilitating the installation of the cover on the sliding seat.
[0019] Optionally, a first baffle plate is hinged to the inner top wall of the inlet and outlet, and an elastic sheet is fixedly installed between the first baffle plate and the inner side wall of the cover away from the sliding seat. The first baffle plate rotates inward toward the cover and abuts against the paint roller.
[0020] By adopting the above technical solution, the first baffle plate and the elastic sheet are used to block the gap between the paint roller and the inner top wall of the inlet and outlet, thereby reducing the occurrence of paint sprayed from the nozzle flowing out of the inlet and outlet. At the same time, the first baffle plate scrapes off the paint on the paint roller, thereby reducing the occurrence of excessive paint dripping from the paint roller.
[0021] Optionally, the inner wall of the cover away from the sliding seat is provided with a second baffle plate and a first connecting plate. The second baffle plate is inclined and gradually approaches the sliding seat from the bottom to the top. The first connecting plate is vertically arranged. The bottom side of the second baffle plate is connected to the bottom side of the first connecting plate. The second connecting plate is fixedly installed on the top side of the first connecting plate. The second connecting plate is horizontally arranged. A third connecting plate is fixedly installed on the side of the second connecting plate away from the first connecting plate. The third connecting plate is vertically arranged and fits against the outer wall of the cover away from the sliding seat. Multiple discharge holes are provided at the connection between the second baffle plate and the first connecting plate.
[0022] By adopting the above technical solution, the second baffle is hung on the inner bottom wall of the inlet and outlet via the first connecting plate, the second connecting plate, and the third connecting plate. The second baffle then abuts against the paint roller, facilitating the scraping off of some paint from the roller and reducing the likelihood of excessive paint dripping. After the second baffle presses the paint off the roller, the paint falls directly into the interior of the cover, or partially drains into the cover through the discharge hole.
[0023] Optionally, a cam is rotatably mounted on the side of the cover away from the sliding seat, and the cam abuts against the bottom side of the third connecting plate.
[0024] By adopting the above technical solution, the cam is turned to push the third connecting plate up, thereby facilitating the adjustment of the clamping force of the second baffle plate on the paint roller.
[0025] An exterior wall coating application method includes the following steps:
[0026] Based on the application range of the exterior wall coating device, the exterior wall of the building is divided into multiple coating areas;
[0027] A suspension system is installed on the top side of the building, and the exterior wall painting device is connected to the suspension system by a traction rope. The painting rollers and wheels are attached to the exterior wall of the building.
[0028] The mobile suspension system and exterior wall coating device are moved to a coating area to apply the coating until each coating area is completed.
[0029] By adopting the above technical solution, construction workers can use an exterior wall coating device to coat the exterior walls of buildings, thereby reducing the time that construction workers spend working at heights and improving the safety of coating exterior walls.
[0030] In summary, this application includes at least one of the following beneficial technical effects:
[0031] 1. The machine body is connected to the top side of the building by a traction rope, so that the rollers and the painting rollers are pressed against the exterior wall of the building. Then, the paint is supplied to the painting rollers by the feeding mechanism. The first linear module, the second linear module and the hoist drive the painting rollers to move to different positions on the exterior wall to apply the paint, thereby reducing the time for construction workers to work at height and thus improving the safety of painting the exterior wall.
[0032] 2. When the sliding seat moves to the top of the second linear module, the support block and the bottom side of the first pressure block press against each other. When the sliding seat moves to the bottom of the second linear module, the support block and the top side of the second pressure block press against each other, which facilitates the paint roller to gently abut against the exterior wall, thereby reducing the occurrence of paint roller friction damage to the exterior wall when the first linear module drives the second linear module to move.

[0042] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.
[0043] This application discloses an exterior wall coating device and construction method.
[0044] Reference Figure 1 An exterior wall coating device includes a body 1, with lifting machines 2 fixedly installed on both sides of the body 1. Each lifting machine 2 is equipped with a traction rope 3, one end of which is connected to the top side of the building, facilitating the suspension of the body 1 on the exterior wall. The lifting machines 2 and the traction rope 3 work together to facilitate the raising and lowering of the body 1 on the exterior wall.
[0045] Reference Figure 1 , Figure 2 Safety locks 4 are installed on both sides of the machine body 1, and safety ropes 5 are attached to the safety locks 4. The top of the safety rope 5 is connected to the top side of the building, and a counterweight 6 is fixedly installed at the bottom of the safety rope 5. The counterweight 6 keeps the safety rope 5 taut. When the traction rope 3 breaks, the machine body 1 falls, and the safety locks 4 will lock the safety rope 5, thereby reducing the possibility of the machine body 1 falling. A suspension device for the suspended basket is installed on the top side of the building, and the safety rope 5 and the traction rope 3 are connected to the suspension device, which facilitates the connection of the safety rope 5 and the traction rope 3 to the top side of the building.
[0046] Reference Figure 2 Rollers 7 are fixedly installed on the side of the machine body 1 facing the exterior wall of the building, and the machine body 1 is pressed against the exterior wall by the rollers 7. When the machine body 1 is raised or lowered, the rollers 7 roll on the exterior wall, thereby reducing the possibility of friction damage between the machine body 1 and the exterior wall.
[0047] Reference Figure 1A blower 33 is embedded on the side of the unit 1 facing away from the exterior wall, and a pressure sensor is built into the unit 1. The pressure sensor generates a pressure signal based on the reaction force of the roller 7 on the exterior wall and sends it to the unit 1. The unit 1 drives the blower 33 according to the pressure signal. When the pressure signal increases, the unit 1 reduces the power of the blower 33, thereby saving energy. When the pressure signal decreases, the unit 1 increases the power of the blower 33, so that the unit 1 can be pressed tightly against the exterior wall by the roller 7.
[0048] Reference Figure 2 , Figure 3 A first linear module 8 is fixedly installed on the side of the machine body 1 facing the exterior wall of the building, and a second linear module 9 is installed on the first linear module 8. The first linear module 8 drives the second linear module 9 to move horizontally. The second linear module 9 is equipped with a sliding seat 10, and the second linear module 9 drives the sliding seat 10 to rise and fall.
[0049] Reference Figure 3 , Figure 4 A paint roller 11 is provided on the side of the sliding seat 10 away from the second linear module 9, and first connecting rods 12 are fixedly installed at both ends of the paint roller 11. The sliding seat 10 has mounting holes 14 for the connecting rods to slide through. A spring 15 and a support block 16 are provided on the side of the sliding seat 10 away from the paint roller 11. The spring 15 is sleeved on the first connecting rod 12, and the support block 16 abuts against the end of the first connecting rod 12 away from the paint roller 11. The spring 15 is fixedly installed between the support block 16 and the sliding seat 10.
[0050] When the machine body 1 is suspended from the exterior wall of the building, the exterior wall compresses the painting roller 11, causing the painting roller 11 to move towards the sliding seat 10. As the painting roller 11 moves towards the sliding seat 10, it pushes the support block 16 away from the sliding seat 10 via the first connecting rod 12. The support block 16 then causes the spring 15 to stretch. After stretching, the spring 15 generates elastic force, which pushes the painting roller 11 against the exterior wall via the support block 16 and the first connecting rod 12, thus facilitating the application of paint to the exterior wall by the painting roller 11.
[0051] Reference Figure 3 , Figure 4 The second linear module 9 has two fixedly mounted first pressure blocks 17 on both sides of its top end. The bottom side of the first pressure block 17 is gradually raised from the side near the sliding seat 10 to the other side and is set at an inclination. The second linear module 9 has two fixedly mounted second pressure blocks 18 on both sides of its bottom end. The top side of the second pressure block 18 is gradually lowered from the side near the sliding seat 10 to the other side and is set at an inclination.
[0052] When the sliding seat 10 moves to the top of the second linear module 9, the support block 16 and the bottom side of the first pressure block 17 press against each other; when the sliding seat 10 moves to the bottom of the second linear module 9, the support block 16 and the top side of the second pressure block 18 press against each other. When the support block 16 presses against the first pressure block 17 or the second pressure block 18, the support block 16 will move away from the sliding seat 10, thereby changing the paint roller 11 from being tightly pressed against the exterior wall to lightly pressing against the exterior wall. When the first linear module 8 drives the second linear module 9 to move, the sliding seat 10 moves to the end of the second linear module 9, thereby reducing the occurrence of friction damage between the paint roller 11 and the exterior wall.
[0053] Reference Figure 2 , Figure 3 The machine body 1 is equipped with a material storage box 19, and the material storage box 19 is equipped with a material feeding mechanism 20.
[0054] Reference Figure 3 , Figure 5 , Figure 6 The feeding mechanism 20 includes a pump 201, a housing 202, a mounting base 203, nozzles 204, a feeding pipe 205, and a recovery pipe 206. The pump body of the pump 201 is fixedly installed on one side of the storage tank 19, and the inlet end of the pump 201 communicates with the interior of the storage tank 19. There are multiple nozzles 204. One end of the feeding pipe 205 is connected to the outlet end of the pump 201, and the other end of the feeding pipe 205 is connected to each nozzle 204. The pump 201 draws paint from inside the storage tank 19, and then the paint well pipe feeding pipe 205 enters each nozzle 204. The nozzle 204 then sprays the paint out.
[0055] Reference Figure 4 , Figure 6 The cover 202 is located on the side of the sliding base 10 away from the second linear module 9. A slot 21 is provided on the side of the sliding base 10 away from the second linear module 9, and the cover 202 is dampedly inserted into the slot 21. The sliding base 10 is provided with a pressure rod 22, and a threaded hole 23 is provided on the periphery of the sliding base 10 for the pressure rod 22 to pass through. The threaded hole 23 communicates with the slot 21.
[0056] Insert the cover 202 into the slot 21, then screw the screw into the screw hole 23 to press the cover 202 firmly, thus facilitating the installation of the cover 202 onto the sliding base 10. When it is necessary to remove the cover 202 from the sliding base 10, unscrew the pressure rod 22 from the screw hole 23, and then pull the cover 202 out of the slot 21, thus facilitating the removal of the cover 202 from the sliding base 10.
[0057] Reference Figure 6An inlet and outlet 24 is provided on the side of the cover 202 away from the sliding seat 10. The paint roller 11 is located inside the inlet and outlet 24. In this embodiment, if the paint roller 11 is not pressed tightly against the outer wall, the spring 15 pushes the paint roller 11 away from the sliding seat 10 through the support block 16 and the first connecting rod 12, and the paint roller 11 remains partially inside the inlet and outlet 24. If the paint roller 11 is pressed tightly against the outer wall, the paint roller 11 moves towards the sliding seat 10, with exactly half of the paint roller 11 inside the cover 202 and the other half extending out of the inlet and outlet 24 outside the cover 202.
[0058] Reference Figure 6 The nozzle 204 is fixedly mounted on the mounting base 203. The mounting base 203 is provided with a second connecting rod 13, one end of which is rotatably inserted into the mounting base 203 and cannot be pulled out of the mounting base 203. The other end of the second connecting rod 13 slides through the top side of the cover 202, and a limiting ring 25 is threaded onto the second connecting rod 13. The mounting base 203 is located inside the cover 202, and the limiting ring 25 is located outside the cover 202. The mounting base 203 is placed inside the cover 202, and then the second connecting rod 13 passes through the top side of the cover 202. Afterward, the limiting ring 25 is screwed into the second connecting rod 13, thereby installing the mounting base 203 inside the cover 202. When the mounting base 203 is installed inside the cover 202, the nozzle 204 faces the inlet / outlet 24, so that when the paint is sprayed from the nozzle 204, the paint falls into the paint roller 11.
[0059] Reference Figure 4 , Figure 6 , Figure 7 The second connecting rod 13 has matching threads on its body and the inner wall of the mounting hole 14. The nozzle 204 can switch between spraying and liquid spraying. When paint needs to be added to the paint roller 11, the nozzle 204 is in liquid spraying mode, facilitating paint addition to the paint roller 11. When paint needs to be sprayed directly onto the exterior wall, the cover 202 and paint roller 11 are removed from the sliding seat 10, and then the second connecting rod 13 is screwed into the mounting hole 14, thereby installing the mounting seat 203 onto the sliding seat 10. The nozzle 204 is then in spray mode, facilitating spraying of the exterior wall.
[0060] Reference Figure 3 , Figure 6 One end of the recovery pipe 206 is connected to the bottom side of the cover 202, and the other end is connected to the top side of the storage box 19. The bottom side of the cover 202 is inclined, gradually rising from the location of the recovery pipe 206. The paint sprayed by the nozzle 204 onto the paint roller 11 falls into the inner bottom wall of the cover 202. The paint then flows to the recovery pipe 206.
[0061] The top of the second linear module 9 is higher than the body 1. When the sliding seat 10 moves to the top of the second linear module 9, the bottom side of the cover 202 is higher than the top side of the storage box 19, which facilitates the flow of the paint inside the recycling pipe 206 into the storage box 19, and thus facilitates the recycling of the paint inside the cover 202.
[0062] Reference Figure 6 A first baffle plate 26 is hinged to the inner top wall of the inlet / outlet 24. An elastic sheet 28 is fixedly installed between the first baffle plate 26 and the inner side wall of the cover 202 away from the sliding seat 10. The elastic sheet 28 pulls the first baffle plate 26, thereby causing the first baffle plate 26 to tilt inwards towards the inside of the cover 202. When the paint roller 11 is located at the inlet / outlet 24, the first baffle plate 26 abuts against the paint roller 11, thereby reducing the occurrence of paint sprayed from the nozzle 204 flowing out of the inlet / outlet 24.
[0063] Reference Figure 6 , Figure 8 A second baffle plate 27 and a first connecting plate 29 are provided on the inner wall of the cover 202 away from the sliding seat 10. The second baffle plate 27 is inclined and gradually approaches the sliding seat 10 from the bottom to the top. The first connecting plate 29 is vertically arranged, and the bottom side of the second baffle plate 27 is fixedly connected to the bottom side of the first connecting plate 29. A second connecting plate 30 is fixedly installed on the top side of the first connecting plate 29, and the second connecting plate 30 is horizontally arranged. A third connecting plate 31 is fixedly installed on the side of the second connecting plate 30 away from the first connecting plate 29, and the third connecting plate 31 is vertically arranged. The first connecting plate 29 is attached to the inner wall of the cover 202 away from the sliding seat 10, and the third connecting plate 31 is attached to the outer wall of the cover 202 away from the sliding seat 10. Multiple discharge holes 34 are provided at the connection between the second baffle plate 27 and the first connecting plate 29. A cam 32 is rotatably mounted on the side of the cover 202 away from the sliding seat 10, and the cam 32 abuts against the bottom side of the third connecting plate 31.
[0064] Rotating the cam 32 causes the second baffle plate 27 to rise and abut against the paint roller 11 via the first connecting plate 29, the second connecting plate 30, and the third connecting plate 31. The second baffle plate 27 facilitates the extrusion of some paint from the paint roller 11, thereby reducing paint dripping from the paint roller 11. Part of the paint scraped off by the second baffle plate 27 falls directly into the cover 202, while the other part is discharged into the cover 202 through the discharge hole 34.
[0065] Reference Figure 1 An exterior wall coating construction method, comprising the following steps, using an exterior wall coating device of this application to coat an exterior wall:
[0066] Based on the application range of the exterior wall coating device, the exterior wall of the building is divided into multiple coating areas;
[0067] A suspension system is installed on the top side of the building. The exterior wall painting device is connected to the suspension system by a traction rope 3. The painting roller 11 and roller 7 are attached to the exterior wall of the building.
[0068] The mobile suspension system and exterior wall coating device are moved to a coating area to apply the coating until each coating area is completed.
[0069] The implementation principle of the exterior wall coating device and construction method in this application embodiment is as follows: The machine body 1 is connected to the top side of the building via a traction rope 3, and then the roller 7 and the paint roller 11 are placed against the exterior wall. The second linear module 9 drives the sliding seat 10 to move up and down, while the feeding mechanism 20 adds paint to the paint roller 11, thereby allowing the paint roller 11 to apply paint to the exterior wall. When the sliding seat 10 moves to one end of the second linear module 9, the first linear module 8 drives the second linear module 9 to move horizontally, thereby allowing the paint roller 11 to move to the uncoated exterior wall. When the second linear module 9 moves to one end of the first linear module 8, the lifting machine 2 drives the machine body 1 to descend, thus facilitating the movement of the paint roller 11 to the uncoated exterior wall.
[0070] As the hoist 2 moves the machine body 1 to the ground, the painting work of the coating device is completed. Afterwards, construction workers apply additional coating to the ground and the top of the building, thus completing the exterior wall coating. By using a coating device to replace manual laborers in applying coatings to the exterior walls at height, the safety of exterior wall coating is improved.
[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
