Description
Technical Field
[0001] This invention relates to the field of building construction technology, specifically to a device for applying waterproof material to exterior windows used in building construction. Background Technology
[0002] Construction engineering refers to the physical engineering project formed through the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipes, and equipment. During construction, waterproofing materials need to be applied to the exterior windows. Exterior windows are windows on the exterior walls of buildings, with the interior and exterior sides facing each other. They connect the interior of the building to the outside world, and because of these windows, leaks often cause mold and blackening of interior decorations, greatly affecting the living environment and the lifespan of the building. Therefore, waterproofing exterior windows is extremely important. Waterproofing treatment for exterior windows usually involves applying one or more layers of highly elastic sealing and waterproofing material. Waterproofing materials are used on building walls for decoration and protection, making the building walls aesthetically pleasing and clean, while also protecting the building walls from rainwater penetration and extending their service life.
[0003] Traditional waterproofing materials for building exterior windows are usually applied manually. However, because multiple coats are required, the labor intensity is high, the workload is large, workers are easily fatigued, and the coating efficiency is low. Furthermore, when coating the exterior of bay windows, the height of the windowsill means that most of the worker's body is above the windowsill, which can easily lead to the risk of falling.
[0004] Therefore, it is necessary to provide a device for applying waterproof materials to exterior windows in building construction to solve the above problems. Summary of the Invention
[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for applying waterproof material to exterior windows for building construction, comprising:

[0014] Furthermore, as a preferred embodiment, the transverse centering assembly does not have a compression spring, a travel plate, or a balance spring, compared to the longitudinal centering assembly, and a rubber pad is fixedly mounted on the outside of the pressure block of the transverse centering assembly.
[0015] Furthermore, preferably, the brushing device includes:
[0016] A sliding guide rail is fixedly mounted on the piston end of the double-rod hydraulic cylinder. Limiting baffles are fixedly mounted on both ends of the sliding guide rail. A drive motor is fixedly mounted on the upper left end of the sliding guide rail. A synchronous belt is fixedly mounted on the output shaft of the drive motor. A rotating screw is coaxially fixed on the other end of the synchronous belt. The rotating screw is placed below the sliding guide rail and is rotatably mounted between two sets of limiting baffles.
[0017] Furthermore, as a preferred embodiment, a cleaning brush assembly is threaded onto the rotating lead screw, and six sets of fixing rods are fixedly installed on the upper end of the cleaning brush assembly. Rotating wheels are rotatably mounted above the fixing rods, and the six sets of rotating wheels slide the cleaning brush assembly onto the sliding guide rail.
[0018] Furthermore, preferably, the cleaning brush assembly includes:

The material container is connected to a conveying pipe, which is fixedly mounted at the center of the lower surface of the sliding plate, and a roller brush is rotatably connected to its lower end.
[0020] The chip removal motor is fixedly equipped with a suction pipe at its inlet, and two sets of suction ducts are installed on it. The two sets of suction ducts are located on both sides of the roller brush. A slag collection bucket is fixedly installed at the outlet of the chip removal motor.
[0021] Furthermore, as a preferred embodiment, two sets of baffles are fixedly mounted at the lower end of the conveying pipe, and the lower side of the baffles is coaxial with the roller brush.

Furthermore, the device includes a cleaning scraper to pre-clean the area to be coated. Dust generated during cleaning is absorbed by a suction fan and collected in a waste bin, further improving coating quality and preventing environmental pollution during the cleaning process.

[0032] Please see Figures 1-5 This invention provides a device for applying waterproofing material to exterior windows during building construction, comprising:
[0033] The fixed block 1 has two sets of longitudinal centering components 2 and two sets of transverse centering components 3 fixedly mounted on its four sides, and the two sets of centering components are placed opposite each other.
[0034] The connecting plate 4 is rotatably mounted on the back side plane of the fixed block 1, and a stepper motor 5 is fixedly mounted on the back side of the connecting plate 4. A double-rod hydraulic cylinder 6 is fixedly mounted on the output shaft of the stepper motor 5.
[0035] The brushing device 7 is fixedly mounted on the piston end of the double-rod hydraulic cylinder 6, and the double-rod hydraulic cylinder 6 is located at the center of the brushing device 7.
[0036] In a preferred embodiment, the connecting plate 4 serves as the connection point between the outside and inside of the window. It is rotatably mounted on the fixing block 1 and equipped with a self-locking block. The plate can be adjusted to a suitable angle and position according to different types and sizes of windows, allowing the fixing block 1 to reach the center of the window without obstruction after activation. During implementation, the painting device 7 is placed on the outside of the window, and the fixing block 1 is placed on the inside. First, the longitudinal centering component 2 is activated and stops when it reaches its limit position. Then, the transverse centering component 3 is activated and stops when it reaches its limit position. At this point, the fixing block 1 is located at the center of the inside of the window. The stepper motor 5 is activated to first adjust the painting device 7 to the position directly above the outside of the window. Then, the double-rod hydraulic cylinder 6 is activated to move the painting device 7 to the designated painting position directly above the outside of the window. The brushing process begins with the brush moving from left to right. After brushing is complete, the stepper motor 5 is started to rotate 180°, moving the brushing device 7 to the designated brushing position directly below the outer side of the window. The brushing continues from left to right. After brushing is complete, the stepper motor 5 is started to rotate 90° counterclockwise to the right side of the outer side of the window. The length of the double-rod hydraulic cylinder 6 is adjusted to move the brushing device 7 to the designated brushing position and brush from top to bottom. After brushing is complete, the stepper motor 5 is started to rotate 180° to the designated brushing position on the left side of the outer side of the window and brush from top to bottom. After brushing is complete, the stepper motor 5 is started to rotate 90° clockwise to return to the initial position. After a period of rest, the above operation is repeated for a second brushing. After the specified number of brushings is completed, the brushing of the outer window is finished.
[0037] Furthermore, the longitudinal centering component 2 includes:
[0038] The hydraulic cylinder 21 is fixedly embedded in the lower side of the fixed block 1, and an anti-deflection block 22 is fixedly mounted on the lower end of its cylinder body, and a pressure block 24 is fixedly mounted on the lower end of its piston rod.
[0039] The anti-deflection block 22 has longitudinal through holes at both ends, and a guide rod 23 is longitudinally slidably mounted inside it, with the lower end of the guide rod 23 fixedly mounted on the upper end of the pressure block 24.
[0040] The lower end of the pressure block 24 is fixedly equipped with four sets of compression springs 25, and the lower end of the compression springs 25 is fixedly equipped with a travel plate 26.
[0041] In a preferred embodiment, the compression spring 25 is equipped with a control module. When it reaches its compression limit, the control module controls the hydraulic cylinder 21 to stop extending, preventing the hydraulic cylinder 21 from continuing to extend and damaging the device or windowsill. The guide rod 23 is used to counteract the torsional force of the pressure block 24 under high pressure, preventing it from deflecting during operation and causing errors in the device. In practice, the hydraulic cylinders 21 of the two sets of longitudinal centering components 2 are activated simultaneously and continuously extend. After extending a certain distance, the two sets of traveling plates 26 will contact the upper and lower surfaces of the inner windowsill of the outer window, and then the hydraulic cylinders 21 continue to extend until all four sets of compression springs 25 of the two sets of longitudinal centering components 2 reach their compression limit positions and stop.
[0042] Furthermore, relative to the upper longitudinal centering component 2, a balance spring 27 is also fixedly assembled between the pressure block 24 of the lower longitudinal centering component 2 and the traveling plate 26, and the ultimate elastic force of the balance spring 27 is equal to the weight of the device itself.
[0043] In a preferred embodiment, the lower longitudinal centering component 2 bears the weight of the device itself, compared to the upper longitudinal centering component 2. Therefore, the compression spring 25 of the lower longitudinal centering component 2 will reach its compression limit first. At this time, the compression spring 25 of the upper longitudinal centering component 2 still has a margin. The lower longitudinal centering component 2 stops running, while the upper longitudinal centering component 2 continues to run. After it stops, the fixing block 1 will deviate from the center of the outer window, causing device error. Therefore, a balance spring 27 is provided to provide an equal amount of elastic force to the lower longitudinal centering component 2 to counteract the influence of the device's own weight, making the brushing of the device more accurate.
[0044] Furthermore, compared to the longitudinal centering assembly 2, the transverse centering assembly 3 does not have a compression spring 25, a travel plate 26, or a balance spring 27, and a rubber pad is fixedly mounted on the outside of the pressure block 24 of the transverse centering assembly 3.
[0045] In a preferred embodiment, the rubber pad prevents the lateral centering component 3 from damaging the windowsill during the centering process, and the hydraulic cylinders 21 of the two sets of lateral centering components 3 are synchronous hydraulic cylinders. After the longitudinal centering component 2 is completed, the lateral centering component 3 is activated to extend. When one side touches the windowsill first, it will push the device to move to the other side until both ends touch the windowsill and stop. At this time, the device is located at the center of the windowsill.
[0046] Furthermore, the brushing device 7 includes:
[0047] A sliding guide rail 71 is fixedly mounted on the piston end of the double-rod hydraulic cylinder 6, and limit baffles 72 are fixedly mounted on both ends of the sliding guide rail 71. A drive motor 73 is fixedly mounted on the upper left end of the sliding guide rail 71, and a synchronous belt 75 is fixedly mounted on the output shaft of the drive motor 73. A rotating screw 74 is coaxially fixed to the other end of the synchronous belt 75. The rotating screw 74 is placed below the sliding guide rail 71 and is rotatably mounted between the two sets of limit baffles 72.
[0048] Furthermore, a cleaning brush assembly 76 is threaded onto the rotating lead screw 74. Six sets of fixing rods 77 are fixedly installed on the upper end of the cleaning brush assembly 76. Rotating wheels 78 are rotatably mounted above the fixing rods 77, and the six sets of rotating wheels 78 slide the cleaning brush assembly 76 onto the sliding guide rail 71.
[0049] In a preferred embodiment, when the drive motor 73 rotates forward, the cleaning brush assembly 76 moves to the right in a clockwise direction, and vice versa, it moves to the left in a clockwise direction. The limiting baffle 72 is used to restrict the movement position of the cleaning brush assembly 76 and prevent it from running off the track.
[0050] Furthermore, the cleaning brush assembly 76 includes:
[0051] A sliding plate 761 is threadedly mounted on the rotating lead screw 74, and a material container 762 and a chip removal motor 766 are fixedly mounted on it. The material container 762 is connected to a material conveying pipe 763, which is fixedly mounted at the center of the lower surface of the sliding plate 761, and a roller brush 765 is rotatably connected to its lower end.
[0052] The chip removal motor 766 has a suction pipe fixedly installed at its inlet, and two sets of suction ducts 767 are provided on it. The two sets of suction ducts 767 are located on both sides of the roller brush 765. A slag collection bucket 768 is fixedly installed at the outlet of the chip removal motor 766.
[0053] As a preferred embodiment, due to the special nature of building construction, a large amount of dust will adhere to the wall before the exterior window is coated with waterproof material. This dust will hinder the adhesion of the waterproof material and easily cause it to fall off. In traditional construction, it is often scraped off directly, which will cause some air pollution. At the same time, the dust raised can easily cause blurred vision and increase the danger of the work. A dust removal motor 766 is installed to remove the dust in front of the roller brush 765 and collect it into the slag collection bucket 768 by the suction fan 767. This ensures that the waterproof material falls off while preventing pollution. The material conveying pipe 763 is equipped with a vision module below it, which can judge the position of the exterior window and control the falling of the waterproof material. This prevents the sliding guide 71 from being too long and causing the waterproof material to be left unused, resulting in waste of waterproof material and controlling the coating cost to a certain extent.
[0054] Furthermore, two sets of wind baffles 764 are fixedly installed at the lower end of the material conveying pipe 763, and the lower side of the wind baffles 764 is coaxial with the roller brush 765. The wind baffles 764 can block the wind and prevent strong winds from blowing the waterproof material away from the roller brush 765, while preventing dust and other impurities from adhering to the roller brush 765 and causing contamination to the waterproof material.
[0055] Furthermore, a cleaning scraper 769 is fixedly mounted on the lower end of the suction duct 767;
[0056] In a preferred embodiment, the cleaning scraper 769 is adjustable. When applying the first coat, the cleaning scraper 769 is adjusted to the lowest position to accelerate the removal of impurities on the exterior wall, making the wall surface as clean as possible, enhancing the adhesion of the waterproof material, and improving work efficiency. When the device performs repeated brushing, the cleaning scraper 769 is adjusted to the highest position to prevent the cleaning scraper 769 from scraping off the waterproof material.
[0057] Furthermore, a first switching valve 7671 and a second switching valve 7672 are respectively installed on the two sets of suction ducts 767;
[0058] In a preferred embodiment, when the drive motor 73 rotates forward, the cleaning brush assembly 76 moves to the right. At this time, the suction duct 767 on the right is in front of the direction of travel of the roller brush 765, and the first switch valve 7671 is opened. Conversely, the opposite occurs.
[0059] The specific implementation includes the following steps: Adjust the angle of the connecting plate 4 according to the condition of the exterior window, place the brushing device 7 on the outside of the exterior window, and place the fixing block 1 on the inside. First, start the longitudinal centering component 2 and stop when it reaches the limit position. Then, start the transverse centering component 3 and stop when it reaches the limit position. At this time, the fixing block 1 is located at the center position on the inside of the exterior window. Start the stepper motor 5 to adjust the brushing device 7 to the position directly above. Then, start the double-rod hydraulic cylinder 6 to make the brushing device 7 reach the designated brushing position directly above the outside of the exterior window and make it brush from left to right. After brushing is completed, start the stepper motor 5 to rotate 180° so that the brushing device 7... Move the brushing device to the designated brushing position directly below the outer side of the window and brush from left to right. After brushing, start the stepper motor 5 and rotate it 90° counterclockwise to the right side of the outer side of the window. Adjust the length of the double-rod hydraulic cylinder 6 to bring the brushing device 7 to the designated brushing position and brush from top to bottom. After brushing, start the stepper motor 5 and rotate it 180° to the designated brushing position on the left side of the outer side of the window and brush from top to bottom. After brushing, start the stepper motor 5 and rotate it 90° clockwise to return to the initial position. After standing still for a period of time, repeat the above operation for a second brushing. After completing the specified number of times, the brushing work of the outer window is completed.
