Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of construction equipment, and in particular relates to a wall facade scraping equipment. Background Art
[0002] Plastering and plastering on the wall are necessary steps in construction and decoration projects. The existing wall plastering and plastering processes are mainly divided into manual plastering and semi-automatic plastering machines. The manual plastering process involves workers laying out lines (laser lines or ink lines), then applying ribs, applying mortar to the wall, smoothing the surface with a trowel against the ribs, and finally leveling the surface with a 2m aluminum alloy ruler. The trowel is typically a simple aluminum alloy strip, and smoothing is achieved with the ribs. This is a fully manual process with numerous steps and a high workload. Ribbing and cornering require high proficiency. Existing semi-automatic plastering machines typically include a movable frame, a flat plastering plate, positioning devices, and leveling devices. To improve plastering efficiency, the dimensions of these accessories must be maximized during manufacturing. However, when completing work in one room of a building and needing to be moved to another, the machine may not be able to fit through the door due to height and width limitations. Furthermore, reducing the dimensions of these accessories, such as the plastering plate, positioning devices, and leveling devices, would negatively impact the efficiency of plastering the wall facade. Furthermore, because walls are composed of a combination of various building materials, and deviations are inevitable during the construction process, the plastering material is affected by the wall's masonry materials and their thickness. Different parts of a wall require different curing times. Therefore, the wall surface requires meshing before plastering. After the first coat solidifies to a certain degree, a second coat is applied, and this cycle repeats until the desired thickness is reached before leveling. Existing equipment generally begins leveling the plastering material early in its curing phase. Because the mortar contains a certain amount of moisture, leaving time for the uncured mortar to solidify, defects such as hollows and cracks are more likely to occur in thicker areas of the wall plaster, impacting the quality of the plastering work.

DETAILED DESCRIPTION
[0017] The technical solution of the present invention is further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited to the above; The present invention provides a wall facade scraping equipment, such as Figures 1 to 9As shown, it includes a scraping device 1, a main vertical frame 2, an angle-adjusting electric push rod 3, a support 4 and a frame 5.

One side of the main vertical frame 2 is provided with a first guide groove 6, and a first guide bar 7 is provided in the first guide groove 6. The first guide bar 7 is also fixedly connected to the hinge support block 8, and the hinge support block 8 is respectively hinged to the piston rod of the angle-adjusting electric push rod 3 and the support 4. The other side of the main vertical frame 2 is provided with a second guide groove 9, and a second guide groove 9 is provided in the second guide groove The second guide bar 10 is also fixedly connected to the positioning block 11. The scraping device 1 includes a supporting block 12, a vertical block 13, a main pulley 14 and a main scraping rope 15. The vertical block 13 is fixedly connected to the left and right ends of the supporting block 12, and the main pulley 14 is fixedly connected to the upper end of the vertical block 13. The main scraping rope 15 is a closed loop shape, and the main scraping rope 15 is wrapped around the outer circumference of all the main pulleys 14. The supporting block 12 is also fixedly connected to one side of the positioning plate 16, and the other side of the positioning plate 16 is hung on the positioning block 11.
[0018] By adopting the technical solution provided by the present invention, a scraping rope is used instead of the flat scraping board commonly used in the prior art to scrape the wall. On the one hand, the scraping rope and the ash box are parallel to the wall, and at least a part of the scraping rope is aligned with the front end of the ash box along the vertical plane. The scraping rope and the front end of the ash box scrape off excess mortar at the same time and collect it in the ash box, so as to prevent the mortar from falling to the ground, avoid environmental pollution, and improve the construction environment; on the other hand, the scraping rope is lighter, easier to load and unload, and easier to maintain. During the equipment manufacturing process, the scraping rope can be made as long as possible, thereby meeting the demand for improving the efficiency of plastering construction and reducing the equipment manufacturing cost. In the process of transferring the equipment, the auxiliary frame and the main frame can be folded, thereby reducing The overall height and size of the equipment are such that the scraping device is directly hung on the main vertical frame through a positioning plate, making the entire scraping device easy to load and unload, and the scraping device can be separated from the equipment in a timely manner. When the longitudinal length allows, the front casters change the rolling direction, and the rotating support plate can also support the scraping device to prevent the scraping device from touching the ground, so that the construction equipment can pass through the building door in the longitudinal direction, making it easier for the construction equipment to be transferred and moved. In addition, before using the scraping equipment to scrape the wall, a mortar sprayer has been used to spray the wall multiple times, leaving a certain interval time for each spraying to reach the expected thickness. At this time, when the scraping equipment is used to scrape off excess mortar, hollowing and cracks inside the mortar are avoided, thereby improving the quality of the plastering.
[0019] Specifically, the main scraping rope 15 can be replaced by a steel wire rope. A rope tightener 17 is also installed on the main scraping rope 15, and the support block 12 can be replaced by an aluminum profile. A rope tightener 17 is also installed on the scraping rope. Preferably, the rope tightener 17 adopts a closed basket-type rope tightener with a nominal diameter of M8 and a load-bearing capacity of more than 200kg. The rope tightener 17 is used to adjust the length of the main scraping rope 15 to tighten the main scraping rope 15, ensure that the main scraping rope 15 always scrapes along a straight line, and enable the scraping rope to easily scrape scraping materials with different degrees of solidification. There are two positioning plates 16, and the two positioning plates 16 are arranged on the left and right sides of the frame 5. Preferably, the positioning plate 16 is U-shaped.
[0020] In addition, the scraping device 1 also includes a secondary pulley 18 and a secondary scraping rope 19. The secondary pulley 18 is fixedly connected to the lower end of the vertical block 13. The secondary scraping rope 19 is in a closed loop shape and is wound around the outer circumference of all secondary pulleys 18. Preferably, the secondary scraping rope 19 can be replaced with a steel wire rope. A rope tightener 17 is also installed on the secondary scraping rope 19. The rope tightener 17 is used to adjust the length of the secondary scraping rope 19, tightening the secondary scraping rope 19 to ensure that the secondary scraping rope 19 always scrapes along a straight line.
[0021] In addition, the scraping device 1 also includes an ash box 20 and an electric push rod 21 for turning the box. The electric push rod 21 for turning the box is hinged to the support block 12. One side of the ash box 20 is hinged to the support block 12 using a hinge, and the other side of the ash box 20 is hinged to the piston rod of the electric push rod 21 for turning the box. The upper end of the ash box 20 is open and its open end is arranged below the main scraping rope 15. The ash box 20 can be replaced by an aluminum profile. The edge of the upper end of the ash box 20 naturally forms a sharp scraping blade, and the piston rod of the electric push rod 21 for turning the box is a rigid chain. By adopting the technical solution of the present invention, the scraping rope and the ash box are parallel to the wall, and at least a part of the scraping rope is aligned with the front end of the ash box along the vertical plane. The scraping rope and the front end of the ash box scrape off excess mortar at the same time to prevent the mortar from falling on the ground and causing pollution. When the operator needs, the piston rod of the box-turning electric push rod 21 is extended to flip the ash box 20, thereby pouring the collected mortar to a predetermined collection location for easy reuse after processing, thereby avoiding environmental pollution.
[0022] In addition, the ash box 20 is also fixedly connected to the pull rod 22, and the pull rod 22 is accommodated in the ash box 20. With the technical solution of the present invention, when the equipment needs to be transferred through a narrow space such as a door, the operator can apply a pulling force to the pull rod 22 to quickly remove the entire scraping device, making it easier to transfer the construction equipment.
[0023] Specifically, the surface of the positioning member 11 is further provided with a locking guide groove 23, and the surface of the positioning plate 16 is further provided with a positioning hole 24. The dust scraping device 1 also includes a locking screw 25 and a locking nut 26. One end of the locking screw 25 is received in the locking guide groove 23, and the other end of the locking screw 25 is threadedly engaged with the locking nut 26. The locking screw 25 also extends through the positioning hole 24. The positioning hole 24 is a through hole with an oblong shape, and at least one end thereof is flush with the edge of the positioning plate 16. The positioning member 11 can be replaced with an aluminum profile, and the cross-section of the locking guide groove 23 is an inverted T-shape.
[0024] In addition, the wall facade scraping equipment also includes a secondary frame 27, a motor 28, a drum 29, a cable 30, and several fixed pulleys 31. The fixed pulleys 31 are mounted on the surface of the positioning block 11 and the secondary frame 27. The secondary frame 27 is also hinged to the main frame 2. The second guide groove 9 is also provided on the surface of the secondary frame 27. The motor 28 is fixedly connected to the surface of the main frame 2. The output shaft of the motor 28 is fixedly connected to the drum 29. One end of the cable 30 is wound around the outer circumference of the drum 29, and the other end of the cable 30 is fixedly connected to the secondary frame 27. The cable 30 is also wound around the outer circumference of all fixed pulleys 31. Preferably, both the main frame 2 and the secondary frame 27 are made of spliced aluminum profiles, and the cross-sections of the first guide groove 6 and the second guide groove 9 are both inverted T-shaped. The main frame 2 is also hinged to a folding electric push rod 32, and the piston rod of the folding electric push rod 32 is also hinged to the secondary frame 27. The piston rod of the folding electric push rod 32 is retractable. Using the technical solution of the present invention, when wall scraping is being performed, the motor 28 is powered on and running. Since the fixed pulley 31 is installed on the surface of the positioning block 11, the cable 30 causes the positioning block 11 and the scraping device 1 to simultaneously rise and fall and reciprocate, thereby achieving automatic leveling of the wall surface. Since the hinged support block 8 is respectively hinged to the piston rod and the support 4 of the angle adjustment electric push rod 3, before the wall is scraped, the operator can also adjust the angle of the main frame 2 relative to the vertical plane by controlling the angle adjustment electric push rod 3 so that the main frame 2 can always remain parallel to the wall surface, thereby improving the scraping quality. When the equipment needs to be transferred through a narrow space such as a door, the operator can also control the folding electric push rod 32 to fold and lower the secondary frame 27, thereby reducing the overall height of the entire construction equipment, making it easier for the equipment to pass through a narrow space such as a door, and making it easier for the construction equipment to be transferred and moved.
[0025] Specifically, the left and right sides of the main vertical frame 2 are respectively fixedly connected to a first calibration plate 33, the edges of which are provided with calibration teeth 34. The left and right sides of the secondary vertical frame 27 are also respectively fixedly connected to a second calibration plate 35, the edges of which are provided with calibration grooves 36. Using the technical solution of the present invention, after the operator folds down the secondary vertical frame 27 and passes through a door with limited height, the secondary vertical frame 27 needs to be flipped again to a position parallel to the main vertical frame 2 due to the need for wall plastering. At this time, the calibration teeth 34 and the calibration grooves 36 engage with each other, ensuring that the secondary vertical frame 27 and the main vertical frame 2 are restored to their original positions, avoiding position deviation and facilitating improved plastering work quality.
[0026] The wall facade scraping device also includes a buffer pad 37, which is fixedly connected to the top of the secondary vertical frame 27. Using the technical solution of the present invention, when the secondary vertical frame 27 is lifted simultaneously with the main vertical frame 2, the buffer pad 37 first contacts the roof of the house, allowing the main vertical frame 2 and the secondary vertical frame 27 to quickly find their correct positions. Afterwards, the main vertical frame 2 and the secondary vertical frame 27 remain stationary, creating the basic conditions for the scraping device 1 to smooth the wall.
[0027] Specifically, the frame 5 is also fixedly connected to the lifting electric push rod 38, and a sprocket 39 is also installed on the piston rod of the lifting electric push rod 38. The sprocket 39 is meshed with the chain 40. One end of the chain 40 is fixedly connected to the frame 5, and the other end of the chain 40 is fixedly connected to the main vertical frame 2. There are two sprockets 39. The two sprockets 39 are installed on the intermediate shaft 41 using bearings, and the two sprockets 39 are arranged on the left and right sides of the lifting electric push rod 38. The intermediate shaft 41 is fixedly connected to the piston rod of the lifting electric push rod 38. By adopting the technical solution of the present invention, when the operator needs, the lifting electric push rod 38 can be controlled to operate, so that the main vertical frame 2 and the auxiliary vertical frame 27 can be raised and lowered at the same time, and the buffer pad 37 can contact or lose contact with the roof of the house. In addition, the wall facade scraping equipment also includes a rotating support plate 42, front casters 43, rear casters 44, a steering electric push rod 45, and a ground-supporting electric push rod 46. The ground-supporting electric push rod 46, rear casters 44, and steering electric push rod 45 are all fixedly connected to the frame 5. The front casters 43 are fixedly connected to the rotating support plate 42. One end of the rotating support plate 42 is provided with a limiting hole, and the ground-supporting electric push rod 46 is also fitted into the limiting hole. The other end of the rotating support plate 42 is also hinged to the piston rod of the steering electric push rod 45. Preferably, the rotating support plate 42 is L-shaped as a whole. By adopting the technical solution of the present invention, when the operator is performing plastering construction on the wall, the number of the ground-supporting electric push rods 46 is 2, and the 2 ground-supporting electric push rods 46 are respectively arranged on the left and right sides of the frame. By adjusting the ground-supporting electric push rods 46 and contacting the ground, the main vertical frame 2 and the auxiliary vertical frame 27 are kept vertically. The ground-supporting electric push rods 46 are used to fix the equipment at the predetermined construction site. When the piston rod of the ground-supporting electric push rod 46 contacts the ground, the main vertical frame 2 and the auxiliary vertical frame 27 are kept stationary. When the equipment needs to be transferred and moved When the scraper 1 moves to the lowest point, the rotating support plate 42 can also support the scraper 1 to prevent it from contacting the ground, so that the entire construction equipment can pass through the building door in the longitudinal direction, and can also pass through the door without disassembling the scraper 1, making it easier for the construction equipment to be transferred and moved. In addition, the wall facade plastering equipment also includes a stop rod 47 and a stop electric push rod 48. The stop electric push rod 48 is hinged to the frame 5. The piston rod of the stop electric push rod 48 is also hinged to the stop rod 47. One end of the stop rod 47 is hinged to the frame 5, and the other end of the stop rod 47 is close to the ground. Using the technical solution of the present invention, when the operator performs plastering on the wall, the ground-supporting electric push rod 46 is used to fix the equipment at the predetermined construction location. The operator can also control the operation of the stop electric push rod 48 to support the stop rod 47 against the ground, further stably fixing the equipment at the predetermined construction location, laying a foundation for improving the quality of the plastering construction.
