Description

Technical Field

[0001] This utility model belongs to the field of construction equipment technology, and in particular relates to a wall leveling mechanism. Background Technology

[0002] Plastering and mortaring walls are essential steps in building construction and decoration projects. Existing wall plastering and mortaring processes are mainly divided into manual plastering and semi-automatic plastering machine processes. The manual plastering process involves workers first laying out lines (laser lines / ink lines), then creating screeds, applying mortar to the wall, smoothing it with a plasterboard against the screeds, and finally leveling it with a 2m aluminum alloy straightedge. The entire process uses a simple aluminum alloy strip as the plasterboard, and smoothing relies heavily on the screeds. It's entirely manual, with many steps and a large workload. The screeding and work at inside and outside corners require a high level of skill from the workers. Existing semi-automatic plastering machines typically include a movable frame, a flat plasterboard, positioning devices, leveling devices, and other functional accessories. To improve plastering efficiency, the dimensions of these accessories need to be maximized during manufacturing. However, when transferring the semi-automatic plastering machine to another room after completing the work on one, the height and width of the door may prevent the machine from passing through. Conversely, reducing the dimensions of the plasterboard, positioning devices, leveling devices, and other accessories during manufacturing would negatively impact the efficiency of plastering the wall facade. Furthermore, since walls are composed of a combination of various building materials, and deviations are inevitable during the masonry process, the plastering material is affected by the wall masonry materials and the thickness of the plaster itself. Different parts of a wall will have different setting and curing times. Therefore, the wall surface needs to be reinforced with mesh before plastering. After the first coat has set and cured to a certain extent, a second coat is applied, and this process is repeated until the desired thickness is achieved. Finally, the surface is leveled. Current equipment generally begins leveling in the early stages of plastering material setting and curing. Because the mortar contains a certain amount of moisture, and there is a certain amount of time for the unbonded mortar to set and cure, thicker areas of the plastered wall are prone to defects such as hollow tapping and cracks, affecting the quality of the plastering work.

[0009] The wall leveling mechanism also includes a secondary frame, a motor, a drum, a cable, and several fixed pulleys. The fixed pulleys are installed on the positioning block and the surface of the secondary frame. The secondary frame is also hinged to the main frame. The second guide groove is also provided on the surface of the secondary frame. The motor is fixedly connected to the surface of the main frame.

This allows the plastering device to be separated from the equipment as needed. Where the longitudinal length allows, the front casters can change the rolling direction, and the support plate can also support the plastering device, preventing it from touching the ground. This allows the construction equipment to pass through building doors longitudinally, facilitating its relocation. Furthermore, before applying plaster to the wall, the wall is sprayed multiple times with a mortar spraying machine, with a certain interval between each coat to achieve the desired thickness. This prevents hollow areas and cracks from forming within the mortar when the plastering device is used to scrape off excess mortar, improving the plastering quality. Attached Figure Description

Detailed Implementation

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited to the description. This utility model provides a wall leveling mechanism, such as Figures 1 to 9As shown, the device includes a scraping device 1, a main frame 2, an angle-adjusting electric push rod 3, a support 4, and a frame 5. The angle-adjusting electric push rod 3 is fixed to the upper end of the frame 5, and the support 4 is fixed to the lower end of the frame 5. A first guide groove 6 is provided on one side of the main frame 2, and a first guide bar 7 is provided in the first guide groove 6. The first guide bar 7 is also fixed to a hinge block 8. The hinge block 8 is hinged to the piston rod of the angle-adjusting electric push rod 3 and the support 4, respectively. A second guide groove 9 is provided on the other side of the main frame 2, and a second guide bar 7 is provided in the second guide groove 9. The second guide bar 10 is also fixedly connected to the positioning block 11. The ash scraping device 1 includes a support block 12, a vertical block 13, a main pulley 14 and a main ash scraping rope 15. The vertical block 13 is fixedly connected to the left and right ends of the support block 12, the main pulley 14 is fixedly connected to the upper end of the vertical block 13, the main ash scraping rope 15 is in a closed loop shape, and the main ash scraping rope 15 is wound around the outer circumference of all the main pulleys 14. The support block 12 is also fixedly connected to one side of the positioning plate 16, and the other side of the positioning plate 16 is hooked onto the positioning block 11.

[0018] The technical solution provided by this utility model uses a scraping rope instead of the commonly used flat scraping board for wall plastering. Firstly, both the scraping rope and the mortar box are parallel to the wall surface, and at least a portion of the scraping rope is aligned vertically with the front end of the mortar box. The scraping rope and the front end of the mortar box simultaneously scrape away excess mortar and collect it in the mortar box, preventing mortar from falling to the ground, avoiding environmental pollution, and improving the construction environment. Secondly, the scraping rope is lighter, easier to install and remove, and easier to maintain. During equipment manufacturing, the scraping rope can be made as long as possible to meet the need for improved plastering efficiency and reduce equipment manufacturing costs. Furthermore, during equipment relocation, the secondary and main frames can be folded, thus reducing the size of the equipment. The overall height of the equipment is reduced. The plastering device is directly attached to the main frame via a positioning plate, making the entire plastering device easy to load and unload. This allows the plastering device to be separated from the equipment at appropriate times. Where the longitudinal length allows, the front casters can change the rolling direction, and the pivot plate can also support the plastering device to prevent it from touching the ground. This allows the construction equipment to pass through the building doorway longitudinally, making it easier to move the equipment between sites. In addition, before using the plastering device to plaster the wall, the wall surface has already been sprayed multiple times with a mortar spraying machine, with a certain interval between each spray to achieve the expected thickness. When the plastering device scrapes off the excess mortar, it avoids the formation of hollow areas and cracks in the mortar, thus improving the plastering quality.

[0019] Specifically, the main scraping rope 15 can be replaced by a steel wire rope. A tensioner 17 is also installed on the main scraping rope 15, and the support block 12 can be replaced by an aluminum profile. The tensioner 17 is preferably a closed-body basket-type tensioner with a nominal diameter of M8 and a load-bearing capacity of over 200 kg. The tensioner 17 is used to adjust the length of the main scraping rope 15, ensuring that the main scraping rope 15 always scrapes along a straight line, and that the scraping rope can easily scrape off scraping materials with varying degrees of solidification. Two positioning plates 16 are used, positioned on the left and right sides of the frame 5. Preferably, the positioning plates 16 are U-shaped.

[0020] In addition, the ash-scraping device 1 also includes auxiliary pulleys 18 and auxiliary ash-scraping ropes 19. The auxiliary pulleys 18 are fixed to the lower end of the vertical stop block 13. The auxiliary ash-scraping rope 19 is in a closed loop shape and is wound around the outer circumference of all auxiliary pulleys 18. Preferably, the auxiliary ash-scraping rope 19 can be replaced with a steel wire rope. A rope tensioner 17 is also installed on the auxiliary ash-scraping rope 19. The rope tensioner 17 is used to adjust the length of the auxiliary ash-scraping rope 19, so that the auxiliary ash-scraping rope 19 is tightened and ensures that the auxiliary ash-scraping rope 19 always scrapes ash along a straight line.

[0021] In addition, the ash scraping device 1 also includes an ash box 20 and an electric push rod 21 for flipping the ash box. The electric push rod 21 for flipping the ash 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. The other side of the ash box 20 is hinged to the piston rod of the electric push rod 21 for flipping the ash box. The upper end of the ash box 20 is open and its open end is located below the main ash scraping rope 15. The ash box 20 can be made of aluminum profile. The edge of the upper port of the ash box 20 naturally forms a sharp ash scraping blade. The piston rod of the electric push rod 21 for flipping the ash box is a rigid chain. The technical solution of this utility model is adopted in which the mortar scraping rope and the mortar box are parallel to the wall surface, and at least a part of the mortar scraping rope is aligned with the front end of the mortar box along the vertical plane. The mortar scraping rope and the front end of the mortar box scrape off the excess mortar at the same time to prevent the mortar from falling to the ground and causing pollution. When the operator needs it, the piston rod of the electric push rod 21 extends to flip the mortar box 20, thereby pouring the collected mortar to the predetermined collection point for easy reuse after treatment and to avoid environmental pollution.

[0022] In addition, the ash box 20 is fixedly connected to the pull rod 22, and the pull rod 22 is housed inside the ash box 20. Using the technical solution of this utility model, when the equipment needs to be moved through narrow spaces such as doorways, the operator can apply a lifting force to the pull rod 22 to quickly disassemble the entire ash scraping device, making it easy to move the construction equipment.

[0023] Specifically, the surface of the positioning stop 11 is provided with a locking guide groove 23, and the surface of the positioning plate 16 is provided with a positioning hole 24. The scraping device 1 also includes a locking screw 25 and a locking nut 26. One end of the locking screw 25 is accommodated in the locking guide groove 23, and the other end of the locking screw 25 is screwed to the locking nut 26. The locking screw 25 also passes through the positioning hole 24. The positioning hole 24 is an oval through hole, and at least one end of it is flush with the edge of the positioning plate 16. The positioning stop 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 leveling mechanism 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 installed on the surface of the positioning stop 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 fixed to the surface of the main frame 2. The output shaft of the motor 28 is fixed 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 fixed to the secondary frame 27. The cable 30 is also wound around the outer circumference of all the fixed pulleys 31. Preferably, the main frame 2 and the secondary frame 27 are both made of aluminum profile splicing. The cross-section of the first guide groove 6 and the second guide groove 9 is an inverted T-shape. The main frame 2 is also hinged to the 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 telescopic. Using the technical solution of this utility model, when plastering the wall, the motor 28 is powered on and runs. Since the fixed pulley 31 is installed on the surface of the positioning stop 11, the cable 30 causes the positioning stop 11 and the plastering device 1 to move up and down simultaneously, thus achieving automatic plastering of the wall surface. Because the hinge block 8 is hinged to the piston rod of the angle-adjusting electric push rod 3 and the support 4 respectively, before plastering the wall, the operator can also control the angle-adjusting electric push rod 3 to adjust the angle of the main frame 2 relative to the vertical plane, ensuring that the main frame 2 remains parallel to the wall surface, improving the plastering quality. When the equipment needs to be moved through narrow spaces such as doorways, the operator can also control the folding electric push rod 32 to fold down the secondary frame 27, thereby reducing the overall height of the construction equipment and making it easier to pass through narrow spaces such as doorways, facilitating the relocation of the construction equipment.

[0025] Specifically, the left and right sides of the main frame 2 are respectively fixed to the first correction plate 33, and the edge of the first correction plate 33 is provided with calibration teeth 34. The left and right sides of the secondary frame 27 are respectively fixed to the second correction plate 35, and the edge of the second correction plate 35 is provided with calibration grooves 36. With the technical solution of this utility model, when the operator folds down the secondary frame 27 and passes through the height-restricted door, the secondary frame 27 needs to be flipped back to a position parallel to the main frame 2 because plastering is required on the wall. At this time, the calibration teeth 34 and the calibration grooves 36 mesh with each other, which can ensure that the secondary frame 27 and the main frame 2 return to their original positions, avoid positional deviation, and help improve the quality of plastering.

[0026] In addition, the wall leveling mechanism also includes a buffer pad 37, which is fixed to the top of the secondary frame 27. Using the technical solution of this utility model, when the secondary frame 27 is raised simultaneously with the main frame 2, the buffer pad 37 first contacts the roof surface, allowing the main frame 2 and secondary frame 27 to quickly find their positioning. Then, the main frame 2 and secondary frame 27 remain stationary, thus creating the basic conditions for the plastering device 1 to level the wall.

[0027] Specifically, the frame 5 is also fixedly connected to the lifting electric push rod 38. A sprocket 39 is mounted on the piston rod of the lifting electric push rod 38. The sprocket 39 meshes with a chain 40. One end of the chain 40 is fixedly connected to the frame 5, and the other end is fixedly connected to the main frame 2. There are two sprockets 39, which are mounted on an intermediate shaft 41 using bearings. The two sprockets 39 are positioned on the left and right sides of the lifting electric push rod 38, and the intermediate shaft 41 is fixedly connected to the piston rod of the lifting electric push rod 38. Using this invention, the operator can control the lifting electric push rod 38 to move when needed, causing the main frame 2 and the secondary frame 27 to rise and fall simultaneously, with the buffer pad 37 contacting or disengaging from the roof surface. In addition, the wall leveling mechanism also includes a pivot 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 pivot plate 42. One end of the pivot plate 42 is provided with a limiting hole, and the ground-supporting electric push rod 46 is fitted into the limiting hole. The other end of the pivot plate 42 is also hinged to the piston rod of the steering electric push rod 45. Preferably, the pivot plate 42 is L-shaped as a whole. Using the technical solution of this utility model, when the operator is performing plastering on the wall, there are two ground-supporting electric push rods 46. The two ground-supporting electric push rods 46 are respectively set on the left and right sides of the frame. By adjusting the ground-supporting electric push rods 46 and their contact with the ground, the main frame 2 and the secondary frame 27 are kept laterally vertical. The ground-supporting electric push rods 46 are used to fix the equipment at the predetermined construction location. When the piston rod of the ground-supporting electric push rod 46 contacts the ground, the main frame 2 and the secondary frame 27 remain stationary. When it is necessary to move the equipment to another location... When in motion, the controller causes the piston rod of the ground-supporting electric push rod 46 to detach from the ground. If the longitudinal length allows, the piston rod of the steering electric push rod 45 extends, causing the front caster 43 to rotate 90 degrees around the ground-supporting electric push rod 46. When the scraping device 1 moves to its lowest point, the pivot plate 42 can also support the scraping device 1, preventing it from contacting the ground. This allows the entire construction equipment to pass through the building doorway longitudinally, or without disassembling the scraping device 1, making the equipment easier to move between sites. In addition, the wall leveling mechanism 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, and 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 this utility model, 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 make the stop rod 47 rest against the ground, further ensuring the equipment is stably fixed at the predetermined construction location, thus laying the foundation for improving the quality of plastering.

[0028] Specifically, such as Figure 8As shown, the frame 5 is also fixedly connected to the control panel 49. A battery 51 is installed inside the frame 5. An angle sensor 50 is installed along the edge of the main frame 2. The angle sensor 50 is used to detect the tilt angle of the main frame 2 relative to the vertical plane. The angle sensor 50 is preferably an LVT544T dual-axis dual-channel tilt sensor manufactured by Maike Sensors Co., Ltd. A limit switch is also installed at the top of the secondary frame 27. The control panel 49 is equipped with a controller, a display screen, and several buttons. The controller, display screen, buttons, and various electric actuators (angle adjustment, tilting, folding, lifting, steering, ground support, and stop) and battery 51 are also included. Angle sensor 50 is electrically connected to form a control circuit loop, used to adjust the tilt angle of the main frame relative to the vertical plane, the lateral vertical tilt angle, flip the mortar box to discharge mortar, make the scraper move up and down to achieve automatic scraping, flip the secondary frame relative to the main frame, adjust the starting point of the lifting and lowering movement of the main frame and the secondary frame, prevent the scraper from exceeding its travel range and causing damage to the equipment when it is lifted, make the equipment pass through narrow gates along the longitudinal direction, and make the equipment stable on the ground of the predetermined construction site. Battery 51 supplies power to all electrical components and keeps the entire equipment balanced front and back to prevent tipping.
