[0014] A use method of a sealing and waterproof treatment device for prefabricated building component installation, the use method includes the following steps:

[0015] The staff fills the waterproof glue into the storage tank through the filler pipe. At this time, the second motor drives the rotating rod to rotate, so that the rotating rod drives the scraper to rotate in the storage tank, prompting the multiple stirring plates on the scraper to stir the waterproof glue in the storage tank. The scraper in contact with the inner wall of the storage tank can scrape off the waterproof glue sticking to the inner wall of the storage tank during rotation, thus avoiding residue waste. Then, the staff rolls the support column to the connection of two prefabricated building walls through the grip rod and the universal wheels. When moving to the working position, the staff rotates the rotating rod downward through the grip rod;

[0016] At this time, the rotating rod drives the support leg and the special-shaped strip to rotate together, so that the rubber block at one end of the special-shaped strip disengages from the jack, and prompts the support leg to contact the ground, so that the support leg cooperates with the universal wheel to support and fix the support base. The operation is simple and convenient. When working, start the pump body, and use the discharge pipe to spray the waterproof glue in the storage tank to the connection of two building walls. Then, start the first motor to drive the threaded lead screw to rotate, so that the mounting plate moves up and down along the threaded lead screw in the guiding chute through the threaded fit of the guiding sleeve and the threaded lead screw, so as to adjust the working height to smear the high gaps. When the mounting plate moves;

[0017] Start the electric push rod to push the brush plate, so that the brush plate contacts the building wall. The third motor can drive the curved push rod to rotate. One end of the rotating curved push rod slides in the strip groove and pushes the cross plate, prompting the cross plate to slide back and forth horizontally on the support plate. The cross plate can drive the brush plate to move synchronously, and then the sprayed waterproof glue is leveled by the brush plate, so that the waterproof glue is smeared more evenly.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In the present invention, by setting the threaded lead screw, guiding sleeve, mounting plate, support plate, cross plate, strip groove, curved push rod, electric push rod and brush plate, the staff starts the third motor to drive the curved push rod to rotate, prompting one end of the curved push rod to slide in the strip groove. As the curved push rod rotates, the cross plate is pushed by the curved push rod, prompting the cross plate to slide back and forth horizontally on the support plate. The sliding cross plate can drive the brush plate to move synchronously. Then, start the electric push rod to push the brush plate, so that the brush plate contacts the building wall, so as to level the waterproof glue at the gap. The first motor can drive the threaded lead screw to rotate. Using the threaded fit of the guiding sleeve and the threaded lead screw, the mounting plate can move along the threaded lead screw in the guiding chute, prompting the mounting plate to drive the brush plate to move up and down, so as to smear the high gaps, reducing the labor intensity of workers and improving the efficiency of waterproof treatment.

[0020] 2. In the present invention, by providing universal wheels, rotating rods, gripping rods, support legs, special-shaped strips, rubber pads, rubber blocks and jacks, when it is necessary to fix the position of the support base, the staff can push the gripping rod downward to cause the rotating rod to rotate. As the rotating rod rotates, the support legs will gradually come into contact with the ground, and the rubber pads will be squeezed until they fit the ground, so that the support legs can support and position the support base to prevent the support base from sliding accidentally. When it is necessary to move, by pushing the gripping rod upward, the support legs are made to move away from the ground. At this time, the rotating rod will drive the special-shaped strip to rotate, causing the rubber block to be inserted into the jack, thereby fixing the rotating rod to prevent the support legs from rotating when moving the support base.

[0021] 3. In the present invention, by providing a second motor, a rotating rod, a scraping plate and a stirring plate, the staff can start the second motor, and the second motor drives the scraping plate to rotate through the rotating rod. As the scraping plate rotates, the multiple stirring plates on the scraping plate can stir the waterproof glue in the storage tank to keep the waterproof glue flowing, and the scraping plate in contact with the inner wall of the storage tank can scrape off the waterproof glue adhering to the inner wall of the storage tank during rotation, thus avoiding residue and waste.

[0029] The technical solution of the present application will be further described in detail below in conjunction with specific embodiments.

[0030] As Figures 1-6 shown, the present invention provides a technical solution: a sealing and waterproof treatment device for installing prefabricated building components, including a support base 1, a support column 2 fixedly connected to the support base 1, and a plurality of universal wheels 3 installed below the support base 1. There are two support bases 1 in total, which are respectively fixedly connected to both sides of the support column 2. There are four universal wheels 3 in total, which are evenly distributed in a rectangular array below the two support bases 1. An anti-slip rubber layer is provided on the outer contour of the universal wheels 3. By rolling the universal wheels 3, it is convenient for the staff to push the support base 1, so that the support base 1 can be moved to the working position, improving the flexibility and practicability of use. Moreover, the anti-slip rubber layer on the outer contour of the universal wheels 3 can increase the contact friction with the ground and prevent accidental sliding during work.

[0031] A rotating rod 4 is rotatably connected to the support base 1. A grip rod 5 is fixedly connected to the rotating rod 4. Support legs 6 are fixedly connected to both ends of the rotating rod 4. A special-shaped strip 7 is fixedly connected to the rotating rod 4. The support legs 6 are connected to the rotating rod 4 at an angle of 45° in the vertical direction, and a rubber pad 31 is connected to the support legs 6. A jack 32 is opened on the support base 1. The special-shaped strip 7 is designed in a C shape and one end is connected with a rubber block 33. The rubber block 33 is inserted into the jack 32. By rotating the rotating rod 4 through the grip rod 5, during the process of the rubber block 33 being inserted into the jack 32, the rubber block 33 will be extruded and deformed, so that when it enters the jack 32, it will be in close contact with the inner wall of the jack 32, thereby fixing the rotating rod 4 and preventing the rotating rod 4 from accidentally rotating when the support base 1 is pushed to move, and avoiding the support legs 6 contacting the ground and affecting the movement.

[0032] A guiding chute 8 is opened on the support column 2. Two guiding rods 30 are fixedly connected in the guiding chute 8. The two guiding rods 30 are distributed on both sides of the threaded screw rod 10. The guiding rods 30 are slidably matched with the connecting through holes 29. Through the connecting through holes 29, the mounting plate 11 can slide along the guiding rods 30. Thus, when the threaded screw rod 10 rotates and the mounting plate 11 moves, the two guiding rods 30 can guide, so that the mounting plate 11 can move smoothly in the guiding chute 8 and avoid sliding deviation.

[0033] Above the support column 2, a first motor 9 is fixedly installed. The output shaft of the first motor 9 is connected to a threaded lead screw 10. An installation plate 11 is installed on the threaded lead screw 10. A guide sleeve 12 is connected to the installation plate 11. A connection through hole 29 is provided on the installation plate 11. The threaded lead screw 10 is rotatably connected in the guide chute 8. The guide sleeve 12 is in threaded cooperation with the threaded lead screw 10. By rotating the threaded lead screw 10 with the first motor 9, the installation plate 11 can move along the direction of the threaded lead screw 10 through the guide sleeve 12, so as to adjust the working height and apply waterproof glue to the connection gap at a high place, without the need for workers to climb to high places, improving the safety of the work.

[0034] A connecting plate 13 is fixedly connected below the installation plate 11. A storage tank 14 is fixedly installed on the installation plate 11. One side above the storage tank 14 is fixedly connected with a filler pipe 15. A pump body 16 is installed below the storage tank 14. The storage tank 14 is connected with a discharge pipe 17 through the pump body 16. A second motor 18 is fixedly installed above the storage tank 14. The output shaft of the second motor 18 is connected to a rotating rod 19. A scraping plate 20 is fixedly connected to the rotating rod 19. The scraping plate 20 is integrally designed in a U shape, and the scraping plate 20 is in close contact with the inner wall of the storage tank 14. A plurality of stirring plates 28 are fixedly connected to the inner side of the scraping plate 20. The stirring plates 28 are inclined. The rotating rod 19 is rotatably connected to the storage tank 14. By rotating the rotating rod 19 with the second motor 18, the scraping plate 20 can scrape off the waterproof glue sticking to the inner wall of the storage tank 14, avoiding the residue of the waterproof glue and reducing waste. The stirring plates 28 rotating with the scraping plate 20 can stir the waterproof glue to keep the waterproof glue flowing.

[0035] A third motor 21 is fixedly installed on the connecting plate 13. Support plates 22 are fixedly connected to both sides of the connecting plate 13. A cross plate 23 is slidably connected to the support plates 22. A strip-shaped groove 27 is provided on the cross plate 23. The strip-shaped groove 27 is vertically arranged on the cross plate 23. One end of a curved push rod 26 slides in the strip-shaped groove 27. Brush hairs are provided above, below and on the side away from the electric push rod 24 of the brush plate 25. Electric push rods 24 are fixedly connected to both sides of the cross plate 23. The movable ends of the electric push rods 24 are fixedly connected to a brush plate 25. The output shaft of the third motor 21 is connected to a curved push rod 26. By rotating the curved push rod 26 with the third motor 21, the curved push rod 26 is urged to push the cross plate 23 to slide back and forth, so as to drive the brush plate 25 to move through the cross plate 23, enabling the brush plate 25 to smooth the waterproof glue at the gap, so that the waterproof glue is applied more evenly to improve the sealing and waterproof effect.

[0036] A usage method of a sealing and waterproof treatment device for prefabricated building component installation, the usage method includes the following steps:

[0037] The staff fills the waterproof glue into the storage tank 14 through the filling pipe 15. At this time, the second motor 18 drives the rotating rod 19 to rotate, so that the rotating rod 19 drives the scraper 20 to rotate in the storage tank 14, prompting the multiple stirring plates 28 on the scraper 20 to stir the waterproof glue in the storage tank 14. The scraper 20 in contact with the inner wall of the storage tank 14 can scrape off the waterproof glue adhering to the inner wall of the storage tank 14 during rotation, thus avoiding residue and waste. Then, the staff rolls the support column 2 to the connection of the two prefabricated building walls through the grip rod 5 and the universal wheels 3. When moving to the working position, the staff rotates the rotating rod 4 downward through the grip rod 5;

[0038] At this time, the rotating rod 4 drives the support leg 6 and the special-shaped strip 7 to rotate together, so that the rubber block 33 at one end of the special-shaped strip 7 disengages from the jack 32, and prompts the support leg 6 to contact the ground, so that the support leg 6 cooperates with the universal wheels 3 to support and fix the support base 1. The operation is simple and convenient. When working, start the pump body 16, and use the discharge pipe 17 to spray and squeeze the waterproof glue in the storage tank 14 to the connection of the two building walls. Then, start the first motor 9 to drive the threaded lead screw 10 to rotate, so that the mounting plate 11 moves up and down along the threaded lead screw 10 in the guiding chute 8 through the threaded fit of the guiding sleeve 12 and the threaded lead screw 10, so as to adjust the working height to apply to the high gap. When the mounting plate 11 moves;

[0039] By starting the electric push rod 24 to push the brush plate 25, the brush plate 25 contacts the building wall. The third motor 21 can drive the curved push rod 26 to rotate. One end of the rotating curved push rod 26 slides in the strip-shaped groove 27 and pushes the cross plate 23, prompting the cross plate 23 to slide back and forth horizontally on the support plate 22. The cross plate 23 can drive the brush plate 25 to move synchronously, and then level the sprayed waterproof glue through the brush plate 25, so that the waterproof glue is applied more evenly.
