Description

Technical Field

[0001] This utility model relates to the field of dust-free wall sanding technology, and in particular to a lifting dust-free wall sanding construction device. Background Technology

[0002] Wall sanding is a key process in decoration projects to improve the smoothness of the wall surface and the adhesion of the paint. It removes the base layer defects by means of machinery or manual methods, laying a quality foundation for subsequent construction. It thoroughly removes floating dust, old paint film, particle protrusions and joint residues (such as knife marks from putty application), eliminates surface roughness differences, ensures uniform adhesion of the putty layer, and avoids cracking and hollowing later.

[0003] Publication No. (CN210388579U) discloses a wall sander, including a body assembly and a protective assembly connected to the lower end of the body assembly. The body assembly houses a motor, a motor-driven output shaft, and a sanding disc mounted on the output shaft. The protective assembly includes an upper cover connected to the body assembly, a lower cover fixed to the lower end of the upper cover, and a light strip. The protective assembly has a first cavity with a downward opening, which houses the sanding disc. A second cavity for housing the light strip is sandwiched between the lower cover and the upper cover. The second cavity has an outer side wall and an inner side wall on its two sides, respectively. The outer side wall faces the light strip and is transparent. The outer side wall is integrally formed with the upper cover or the lower cover. This integral design simplifies installation and saves costs.

[0004] Existing wall sanding devices do not have the function of collecting dust generated during the wall sanding process in actual use, causing wall dust to float in the surrounding air, polluting the environment and making it inconvenient for workers to use. Therefore, those skilled in the art have provided a lifting dust-free wall sanding construction device to solve the problems mentioned in the background art. Utility Model Content

[0005] This utility model provides a lifting dust-free wall grinding construction device.

[0006] This utility model provides a lifting-type dust-free wall grinding construction device, which adopts the following technical solution:

[0007] A lifting-type dust-free wall sanding device includes a base with a movable component at its bottom. An electric push rod is fixedly mounted on the top of the base, and a lifting plate is fixedly mounted on the output end of the electric push rod. A fixed plate is fixedly mounted on the top of the lifting plate, and a sanding component is mounted on one side of the fixed plate. A housing is fixedly connected to the top of the lifting plate, and a dust removal component is installed inside the housing. Activating the electric push rod moves the lifting plate, allowing adjustment of the sanding disc's height. During movement, the lifting plate slides a telescopic rod inside a telescopic sleeve, ensuring stability. Activating a first motor rotates the first shaft at its output end, allowing the sanding disc to sand the wall. Activating a second motor rotates a fan blade, drawing dust into the housing through a suction pipe. This structure enables wall sanding, preventing dust from scattering in the air and facilitating operation.

[0008] Optionally, the movable component includes four support columns, each of which is fixedly connected to a caster wheel at its bottom, and the four support columns are fixedly installed at the bottom of the base.

[0009] Optionally, a telescopic sleeve is fixedly connected to the top of the base, and a telescopic rod is slidably installed inside the telescopic sleeve. The top of the telescopic rod is fixedly connected to the bottom of the lifting plate.

[0010] Optionally, the grinding assembly includes a first motor, a second motor disposed outside the housing, a first rotating shaft fixedly connected to the output end of the first motor, and a grinding disc fixedly connected to one end of the first rotating shaft.

[0011] Optionally, a first support plate is fixedly connected to one side of the fixing plate, and the first motor is fixedly mounted on the first support plate.

[0012] Optionally, the dust removal assembly includes a second motor, the output end of which is fixedly connected to a fan blade, and both sides of the housing are connected to a suction pipe.

[0013] Optionally, a filter plate is fixedly connected inside the housing, a second support plate is fixedly connected to one side of the housing, and the second motor is fixedly mounted on the second support plate.

[0014] In summary, this utility model has the following beneficial effects: By activating the electric push rod, the output end of the electric push rod drives the lifting plate to move, at which point the height of the grinding disc can be adjusted. When the lifting plate moves, it drives the telescopic rod to slide inside the telescopic sleeve, making the lifting plate more stable during movement. By activating the first motor, the first shaft at the output end of the first motor rotates with the grinding disc, allowing the grinding disc to grind the wall surface. By activating the second motor, the output end of the second motor drives the fan blades to rotate, drawing dust from the suction pipe into the housing. Through the above structure, the wall surface can be ground, and dust can be drawn into the housing during grinding, preventing dust from scattering in the air, thus facilitating use by staff.

A dust removal component is installed inside the housing 13. By activating the electric push rod 4, the output end of the electric push rod 4 moves the lifting plate 5, thereby adjusting the height of the grinding disc 12. When the lifting plate 5 moves, it also drives the telescopic rod 7. The sliding installation inside the telescopic sleeve 6 makes the lifting plate 5 more stable when moving. By starting the first motor 9, the first shaft 11 at the output end of the first motor 9 rotates with the grinding disc 12, which then grinds the wall surface. By starting the second motor 14, the output end of the second motor 14 drives the fan blade 16 to rotate, which sucks the dust from the suction pipe 18 into the housing 13. With the above structure, the wall surface can be ground. During grinding, the dust is sucked into the housing 13, preventing the dust from scattering in the air, thus making it more convenient for staff to use.
