Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically a grinding device for prefabricated wall surfaces used in the decoration and renovation of prefabricated buildings. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories, such as floor slabs, wall panels, stairs, and balconies, are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods.

[0003] When decorating the interior of prefabricated buildings, the walls need to be sanded first to remove minor imperfections and make the walls smoother, finer, and more uniform, facilitating the application of subsequent coatings, putty, and paint. Currently, most prefabricated wall sanding devices commonly used for prefabricated building decoration are similar in overall structure, mainly relying on manual handheld sanding. The sanding equipment uses a motor to drive the sanding disc to rotate continuously. The disc fits against the wall surface, sanding and scraping away protrusions and powder layers. However, there are some functional shortcomings in actual use, leaving room for improvement. For example, the current handheld sanding equipment relies entirely on the worker's arm to adjust the sanding angle. This is cumbersome when sanding areas such as the top of the wall or non-standard slopes, requiring workers to climb to a height for operation, and it lacks the function of easily adjusting the sanding angle.

[0004] Now, a novel prefabricated wall surface grinding device for prefabricated building decoration is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated wall surface grinding device for prefabricated building decoration and renovation, so as to solve the problem mentioned in the background art that it does not have the function of easily adjusting the grinding angle.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precast wall surface grinding device for prefabricated building decoration, comprising a gripping rod, a controller fixedly connected to the bottom of the front end of the gripping rod, a fixed fork fixedly connected to the top end of the gripping rod, a motor mounting housing movably connected between the two sides inside the fixed fork, a grinding mold cover fixedly connected to the top end of the motor mounting housing, a drive motor installed at the bottom end of the motor mounting housing, a grinding disc fixedly connected to the output end of the drive motor, a power cord movably connected to the left side of the controller, and angle adjustment components for adjusting the grinding angle provided on both sides of the motor mounting housing.

[0007] The angle adjustment assembly includes two sets of hinge shafts, which are fixedly connected to the left and right sides of the motor mounting housing, respectively. An external toothed ring is fixedly connected to the outside of the hinge shaft. Side covers are fixedly connected to the left and right sides of the fixed fork, respectively. A miniature electric cylinder is installed at the bottom inside the side cover, and a limit tooth plate is fixedly connected to the output end of the miniature electric cylinder.

[0008] As a further technical solution of this utility model, the hinge shaft passes through the fixed fork and extends to the outside, and the hinge shaft is symmetrically distributed about the vertical center line of the motor fixing housing.

[0009] As a further technical solution of this utility model, there is a distance between the two sides of the hinge shaft and the two sides inside the side cover, and the side cover and the hinge shaft do not contact each other.

[0010] As a further technical solution of this utility model, the tooth block at the top of the limiting tooth plate meshes with the tooth groove outside the outer tooth ring, and the controller and the micro electric cylinder are electrically connected.

[0011] As a further technical solution of this utility model, an annular light groove is provided at the top of the outer surface of the mold cover, an annular light strip is glued inside the annular light groove, and an annular diffuser is fixedly connected to the top of the outer surface of the mold cover.

[0012] As a further technical solution of this utility model, the outer diameter of the annular diffuser is the same as the outer diameter of the mold cover, and the controller and the annular lamp are electrically connected.

[0013] As a further technical solution of this utility model, a dust suction pipe is movably connected to the rear end of the bottom of the mold cover, and a vacuum cleaner interface is movably connected to the end of the dust suction pipe.

[0014] As a further technical solution of this utility model, the suction tube passes through the interior of the grip rod and extends out from the bottom, and the interior of the mold cover and the suction tube are connected.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the prefabricated wall grinding device for prefabricated building decoration not only realizes the function of easy adjustment of grinding angle, but also realizes the function of easy observation by lighting, and also realizes the function of easy dust removal.

[0016] (1) By setting a side cover, hinge shaft, external toothed ring, limiting tooth plate and micro electric cylinder, when the prefabricated building is assembled, it enters the decoration pre-processing stage. The operator enters the site and holds the grip rod to put the grinding disc against the wall. The drive motor drives the grinding disc to rotate at high speed to grind the wall. During the grinding process, the limiting tooth plate locks the external toothed ring upward. When it is necessary to adjust the grinding angle, the grinding disc is pressed against the wall and the micro electric cylinder is started to retract it. After the limiting tooth plate is separated from the external toothed ring, the hinge shaft is no longer restricted. The overall angle of the motor fixing shell and the grinding disc can be adjusted. After adjusting to the appropriate angle, the micro electric cylinder extends and locks the external toothed ring again through the limiting tooth plate. The angle is fixed, which is convenient for grinding the top of the wall, the slope and other areas, and realizes the function of easy adjustment of the grinding angle.

[0017] (2) By setting up a ring light groove, a ring light strip and a ring soft light cover, during the polishing process, the ring light strip in the ring light groove is powered on and emits light. After the light is softened by the ring soft light cover, it shines on the wall surface of the polishing area. When there are pits or bumps on the wall surface, they can be directly observed, thus realizing the function of convenient observation through lighting.

[0018] (3) By setting up a mold cover, a suction pipe and a vacuum cleaner interface, when using it, the vacuum cleaner interface of the suction pipe is connected to the industrial vacuum cleaner before the grinding begins. During the grinding process, the industrial vacuum cleaner continuously sucks in the dust generated by the grinding along the mold cover and the suction pipe into the industrial vacuum cleaner, reducing indoor dust pollution and realizing the function of easy dust removal.

[0026] Example: Please refer to Figure 1-5 A prefabricated wall surface grinding device for prefabricated building decoration includes a gripping rod 1, a controller 2 fixedly connected to the bottom of the front end of the gripping rod 1, a fixed fork 3 fixedly connected to the top end of the gripping rod 1, a motor fixing housing 10 movably connected between the two sides inside the fixed fork 3, a grinding mold cover 9 fixedly connected to the top end of the motor fixing housing 10, a drive motor 11 installed at the bottom end of the motor fixing housing 10, a grinding disc 12 fixedly connected to the output end of the drive motor 11, a power cord 18 movably connected to the left side of the controller 2, and angle adjustment components for adjusting the grinding angle provided on both sides of the motor fixing housing 10.

[0027] Please see Figure 1-5 A prefabricated wall grinding device for prefabricated building decoration also includes an angle adjustment component. The angle adjustment component includes two sets of hinge shafts 5, which are respectively fixedly connected to the left and right sides of the motor fixing housing 10. An external toothed ring 6 is fixedly connected to the outside of the hinge shaft 5. Side covers 4 are respectively fixedly connected to the left and right sides of the fixing fork 3. A micro electric cylinder 8 is installed at the bottom inside the side cover 4. The output end of the micro electric cylinder 8 is fixedly connected to a limit tooth plate 7.

[0028] The hinge shaft 5 passes through the fixed fork 3 and extends to the outside. The hinge shaft 5 is symmetrically distributed about the vertical center line of the motor fixed housing 10. There is a distance between the two sides of the hinge shaft 5 and the two sides inside the side cover 4. The side cover 4 and the hinge shaft 5 do not contact each other. The tooth block at the top of the limiting tooth plate 7 meshes with the tooth groove outside the outer tooth ring 6. The controller 2 and the micro electric cylinder 8 are electrically connected to facilitate the adjustment of the grinding angle.

[0029] Specifically, such as Figure 1 ,and Figure 4 As shown, the grinding disc 12 is pressed against the wall, and the micro electric cylinder 8 is activated to retract it. After the limiting tooth plate 7 disengages from the outer tooth ring 6, the hinge shaft 5 is no longer restricted, and the overall angle of the motor fixing housing 10 and the grinding disc 12 can be adjusted. After adjusting to a suitable angle, the micro electric cylinder 8 extends and locks the outer tooth ring 6 again through the limiting tooth plate 7, thus fixing the angle. The controller 2 and the micro electric cylinder 8 are electrically connected. This technology is existing technology, so it will not be described in detail.

[0030] The top of the outer surface of the mold housing 9 is provided with an annular light groove 13. An annular light strip 14 is glued inside the annular light groove 13. An annular soft light cover 15 is fixedly connected to the top of the outer surface of the mold housing 9. The outer diameter of the annular soft light cover 15 is the same as the outer diameter of the mold housing 9. The controller 2 and the annular light strip 14 are electrically connected. The defects can be easily detected by lighting.

[0031] Specifically, such as Figure 1 and Figure 3 As shown, the ring light strip 14 in the ring light groove 13 is powered on and emits light. The light is softened by the ring diffuser 15 and then shines on the wall surface of the polishing area. When there are pits or bumps on the wall surface, they can be directly observed. The controller 2 and the ring light strip 14 are electrically connected. This technology is existing technology, so it will not be described in detail.

[0032] A vacuum tube 16 is movably connected to the rear end of the bottom of the mold cover 9. A vacuum cleaner interface 17 is movably connected to the end of the vacuum tube 16. The vacuum tube 16 passes through the inside of the grip rod 1 and extends out from the bottom. The inside of the mold cover 9 and the vacuum tube 16 are connected, so dust removal is taken into account during the polishing process.

[0033] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the dust generated during grinding enters the industrial vacuum cleaner along the grinding wheel housing 9 and the suction pipe 16, reducing indoor dust pollution.

[0034] Working Principle: In use, after the prefabricated building is assembled, it enters the pre-treatment stage of decoration. The operator enters the site and holds the handle 1, placing the grinding disc 12 against the wall. The drive motor 11 drives the grinding disc 12 to rotate at high speed, grinding the wall surface. During grinding, the limiting tooth plate 7 locks the outer tooth ring 6 upwards. When the grinding angle needs adjustment, the grinding disc 12 is pressed against the wall, and the micro electric cylinder 8 is activated to retract it. After the limiting tooth plate 7 disengages from the outer tooth ring 6, the hinge shaft 5 is no longer restricted, and the overall angle of the motor fixing housing 10 and the grinding disc 12 can be adjusted. After adjusting to the appropriate angle, the micro electric cylinder 8 extends, locking the outer tooth ring 6 again through the limiting tooth plate 7, thus fixing the angle and facilitating grinding of wall tops, slopes, and other areas. During grinding, the annular light strip 14 in the annular light trough 13 is powered on and emits light. The light is softened by the annular diffuser 15 and then shines on the wall surface of the grinding area, making pits and bumps on the wall surface readily visible. Before the polishing begins, connect the vacuum cleaner interface 17 of the suction pipe 16 to the industrial vacuum cleaner. During the polishing process, the industrial vacuum cleaner continuously sucks up the dust generated during polishing. The dust generated during polishing enters the industrial vacuum cleaner along the mold cover 9 and the suction pipe 16, reducing indoor dust pollution.
