Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to a grinding and leveling device for building walls. Background Art

[0002] Currently, the most widely used energy-saving measure for building exterior wall structures is exterior wall insulation. The thickness of the insulation layer depends on the local climate and room temperature requirements. Insulation layers are divided into interior and exterior wall insulation. Appropriate exterior wall insulation thickness can improve the thermal insulation performance of the building envelope and reduce building energy consumption. Typically, the wall surface needs to be polished and leveled before installing the insulation layer. Residual solidified cement on the wall can cause unevenness, so it is necessary to remove the residual cement.

[0033] The wall-leaning assembly is connected to the vertical plate through a fixing ring. When the vertical plate moves along the wall, it slides against the wall through the leaning wheels. The leaning wheels can be retracted and retracted by springs to ensure that the vertical plate moves smoothly along the wall.

[0034] Preferably, Figure 2 and Figure 8 As shown, the dust collection duct 51 of the dust collection assembly 5 is provided with a protective cover 55, on the surface of which a filter screen 56 is provided. A support rod 57 is fixedly mounted on the inner wall of the filter cartridge 52, and a cloth strip 58 is tied to the support rod 57. The protective cover and the filter screen cooperate to prevent large cement particles from entering the dust collection duct when the knocking assembly knocks on the wall. The cloth strip is tied to the filter cartridge via the support rod. During the dust collection process of the dust collection fan, the vibration of the cloth strip drives the filter cartridge to vibrate, thereby shaking off dust from the filter cartridge and the dust collection duct wall.

[0035] Preferably, Figure 4 As shown, the cleaning assembly 3 further includes a right-angle support plate 36, the vertical side of which is provided on the vertical plate 1 and located outside the second knocking rod 27, and the horizontal side of which is located between the fixed rod 32 and the sliding rod 33. The right-angle support plate is used to support the sliding rod during rotation, ensure smooth rotation of the sliding rod, and prevent the sliding rod from contacting the first knocking rod and the second knocking rod.

[0036] Preferably, Figure 3 As shown, the transmission gear 35 of the cleaning assembly 3 is connected to the other drive shaft of the dual-axis motor 21 through a transmission 37. The transmission is used to adjust the speed of the double-layer turntable of the cleaning assembly, and the rotation speed of the slide rod on the wall can be adjusted according to the condition of the wall to improve the effect of removing wall scum.

[0037] Preferably, Figure 7 As shown, the baffle 42 of the collecting assembly 4 is a rubber baffle. The rubber baffle can prevent the collecting trough in the collecting assembly from hard contact with the wall, thereby increasing the service life of the collecting assembly and avoiding scratches on the wall.

[0038] Preferably, Figure 5As shown, the surfaces of the first knocking rod 26 and the second knocking rod 27 of the knocking assembly 2 are tapered surfaces 207. The tapered surface is used to improve the knocking effect of the knocking rod on the wall, ensure that the residual cement blocks on the wall are knocked and broken, and improve the flatness of the wall.

[0039] The solidified cement blocks remaining on the wall will cause the wall surface to be uneven, so it is necessary to remove the residual cement blocks on the wall and level the wall surface to facilitate the installation of insulation layer and other decorative construction on the wall. When grinding and leveling the wall surface:

[0040] 1. The knocking assembly knocks the residual cement blocks on the wall. The vertical plate of the device is pressed against the wall and moved slowly. The dual-axis motor is started. The output shaft of the dual-axis motor drives the second rotating drum to rotate, and the second rotating drum drives the first rotating drum to rotate. The rotation directions of the first rotating drum and the second rotating drum are opposite. The first stopper and the second stopper on the first rotating drum and the second rotating drum make the first connecting plate and the second connecting plate reciprocate in the direction of the plate surface of the vertical plate in turn. The spring sleeved on the connecting rod is used to reset the first connecting plate and the second connecting plate. The first connecting plate and the second connecting plate respectively drive the first knocking rod and the second knocking rod to reciprocate and knock the residual cement blocks on the wall, thereby removing the residual cement blocks on the wall.

[0041] 2. The cleaning component is used to clean the residue on the wall after being knocked by the knocking component. The dual-axis motor drives the double-layer turntable to rotate through the transmission. During the rotation of the double-layer turntable, the sliding rod sweeps along the wall to remove the residual ash on the wall.

[0042] 3. Clean the dust. When using the knocking component to knock the remaining cement blocks on the wall and the cleaning component to remove the remaining ash on the wall, start the vacuum fan to suck the dust into the vacuum pipe. The dust in the vacuum pipe enters the filter cartridge, and the filter cartridge regularly cleans the dust through the end cover.

[0043] 4. Cement blocks and residue collection: When the vertical plate moves along the wall, the roller of the collection assembly abuts against the wall and moves along with it. The knocked cement blocks and removed residue fall onto the conveyor belt of the collection trough. The rotation of the roller drives the conveyor belt along the collection trough through the drive shaft, thereby removing the cement blocks and residue on the conveyor belt from the collection trough.

[0044] This device uses a knocking component to knock on the cement blocks on the wall, a cleaning component to clean the residue on the wall, a dust suction component to absorb the dust generated by the knocking and cleaning operations, and a collection component to collect the cement blocks that fall after knocking and the residue during the cleaning process. It can effectively remove the residual cement blocks on the wall, ensure the flatness of the wall, and avoid the dust during the operation process from causing harm to the construction workers.

[0045] The first connecting plate and the second connecting plate of the knocking assembly respectively drive the first knocking rod and the second knocking rod to reciprocate and knock the wall cement blocks, thereby improving the work efficiency of polishing the wall surface and avoiding manual knocking of the wall cement blocks and damage to the wall surface caused by manual knocking.

[0046] At the same time, when the knocking component moves along the wall, the roller of the collecting component contacts the wall and rolls along with it, knocking the fallen cement blocks and cleaning the residues and dropping them onto the conveyor belt of the collecting trough. The conveyor belt is driven by the roller to move the cement blocks and residues out of the collecting trough, and a collecting cylinder can be set to collect the cement blocks and residues moved out of the collecting trough to prevent the cement blocks and residues from being scattered on the construction site.
