Description

Technical Field

[0001] The invention relates to the technical field of wall surface treatment, and in particular to a wall surface pretreatment device for wall panel installation and a use method thereof. Background Art

[0002] The walls of a building generally include load-bearing walls and non-load-bearing walls. Non-load-bearing walls are generally called partition walls. The walls of buildings with brick-concrete structures are generally load-bearing walls. The internal walls of buildings with frame structures that are pre-cast with reinforced concrete are generally partition walls. Partition walls have the functions of sound insulation, heat insulation, and space division. Under existing conditions, in order to beautify the walls, wall panels are often installed. However, the walls need to be flat to achieve the firm fit and installation of the wall panels. For this reason, the walls need to be flattened.

[0003] Existing treatment methods mostly use a wall pretreatment device for decoration and renovation, such as the one disclosed in CN220217763U. Through the setting of the first electric telescopic rod, the wall scraper plate can be driven to move back and forth, so as to move and smooth the wall. However, the wall is larger than the grinder, so it is difficult to achieve flexible multi-point operation using a fixed-mounted grinder. In addition, there are many problems in the process of grinding the wall, such as the wall structure is too hard, and it is very easy for dust to spread during the grinding process due to untimely cleaning, affecting the safety of the operation. This may even cause excessive grinding to affect the structural integrity of the wall itself, which will not only affect the installation of the wall panels but also the structural safety of the wall and the building itself.

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Reference Figure 1-Figure 7A wall surface pretreatment device for wall panel installation includes a body 1, on which a load-bearing mechanism 2 for buffering and supporting the body 1 is arranged.

By arranging the moving pulley 24 elastically supported by the elastic piston key 22, the stability of the body 1 during movement can be ensured, and at the same time, a stable support with a buffering effect can be provided for the grinder 57 to avoid displacement of the body 1 due to severe vibration.

[0047] The body 1 is provided with a braking mechanism 3 for fixing the body 1, and the braking mechanism 3 includes a mountain-shaped cavity 31 opened in the lower end of the body 1, a driving bolt 32 is threadedly installed in the middle opening of the mountain-shaped cavity 31, and a strong spring 33 is installed in the middle opening of the mountain-shaped cavity 31, an active piston 34 that movably resists the driving bolt 32 is welded on the strong spring 33, and a passive piston 35 that cooperates with the active piston 34 is slidably sleeved in the openings at both ends of the mountain-shaped cavity 31. It should be noted that the mountain-shaped cavity 31 is filled with water located between the active piston 34 and the passive piston 35, and a strong suction cup 36 is fixedly installed on the passive piston 35. A countersunk hole structure corresponding to the openings at both ends of the mountain-shaped cavity 31 is opened at the bottom of the body 1. In the process of moving the body 1, the strong suction cup 36 is received in the countersunk hole to avoid bumping. When the body 1 needs to be fixed, the position can be fixed by strongly adsorbing the ground by the strong suction cup 36.

[0048] A load-bearing bracket 4 is integrally provided at the front end of the machine body 1 , and the load-bearing bracket 4 is an L-shaped cross-section structure.

[0049] The load-bearing bracket 4 is provided with a leveling mechanism 5 for grinding the wall, the leveling mechanism 5 includes a driving worm 51 rotatably installed at the front end position of the load-bearing bracket 4, a servo motor for driving the driving worm 51 to rotate is provided on the load-bearing bracket 4, two driven shafts 52 are rotatably installed on the load-bearing bracket 4, and the driven shafts 52 are key-connected with driven worm wheels 53 meshingly connected to the driving worm 51, and the two driven shafts 52 are fixedly sleeved with a traction rocker 54, and the load-bearing bracket 4 is slidably sleeved with a lifting frame 55 that is movably pulled by the traction rocker 54, and the lifting frame 55 is integrally connected with an extension frame 56, and the lifting frame 55 is driven by the servo motor to lift and move in the vertical direction, and a grinder 57 is fixedly provided on the extension frame 56, and the grinder 57 that can be lifted and moved in the vertical direction performs grinding operations on the flat parts of the wall to reduce protrusions on the wall and provide a flat wall surface for wall panel installation.

[0050] The load-bearing bracket 4 is provided with a humidifying mechanism 6 for humidifying the flat part of the wall through the leveling mechanism 5. The humidifying mechanism 6 includes a water tank 61 fixedly installed at the rear end of the load-bearing bracket 4. The water tank 61 is used for filling water. A water hose 62 is fixedly connected to the water tank 61. A splitter 63 is fixedly connected to the water hose 62. The splitter 63 is fixedly connected to high-pressure nozzles 64 circumferentially equidistantly distributed on the extension frame 56. It should be noted that a water pump is provided between the water tank 61 and the water hose 62. Water is sprayed on the flat part of the wall through the high-pressure nozzle 64 for humidification, which can reduce the hardness of the wall structure, reduce the operating difficulty of the grinder 57, and reduce dust diffusion under wet conditions.

[0051] The machine body 1 is provided with a dust removal mechanism 7 cooperating with the leveling mechanism 5 and the humidifying mechanism 6. The dust removal mechanism 7 includes a guide rail 71 integrally arranged on the machine body 1, and a mobile platform 72 is slidably mounted on the guide rail 71. A dust collector 73 corresponding to the grinder 57 is placed on the mobile platform 72. The dust collector 73 is used to absorb dust caused by the grinder 57, thereby realizing clean protection of the working environment.

[0052] A long traction hole 541 is defined in the traction rocker 54 , and a long traction bolt 551 slidably sleeved in the long traction hole 541 is integrally connected to the lifting frame 55 .

[0053] There are four high-pressure nozzles 64, and the grinder 57 is located between the four high-pressure nozzles 64 to fully humidify the flat parts of the wall.

[0054] It should be noted that the specific models and specifications of the grinder 57 and the dust collector 73 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0055] The present invention can be explained by the following operation mode:

[0056] First, the machine body 1 is moved to a predetermined position by the load-bearing mechanism 2. During this process, the moving pulley 24 provides a buffer support for the machine body 1 to ensure the stability of the machine body 1.

[0057] Secondly, the driving bolt 32 is controlled to rotate to apply pressure to the active piston 34. The passive piston 35 is under pressure and drives the strong suction cup 36 to extend out of the openings at both ends of the mountain-shaped cavity 31. The strong suction cup 36 is used to absorb the ground to fix the machine body 1, thereby ensuring the stability of the machine body 1 during operation.

[0058] Next, the driving worm 51 is controlled to rotate, and the driven shaft 52 is driven to deflect through the driven worm wheel 53. The driven shaft 52 pulls the lifting frame 55 along the load-bearing bracket 4 through the traction swing rod 54 to vertically lift and lower until the grinder 57 on the extension frame 56 corresponds to the flat part of the wall.

[0059] Then, the high-pressure nozzle 64 is controlled to open to humidify the flat part of the wall. The high-pressure nozzle 64 uses a spray form to achieve humidification, which reduces water waste and avoids affecting the grinder 57;

[0060] Then, the mobile platform 72 is controlled to move along the guide rail 71, and the dust collector 73 is turned on;

[0061] Finally, the sander 57 is controlled to start and the flat part of the wall is sanded. At the same time, the dust collector 73 is used to absorb dust to ensure the cleanliness of the sanding working environment.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
