Description

Technical Field

[0001] The invention relates to the technical field of wall surface grinding, and in particular to a wall surface grinding device for building construction and a use method thereof. Background Art

[0002] In the field of construction, wall grinding is a key process to ensure the flatness, smoothness and aesthetics of the wall, which has a significant impact on the adhesion and durability of subsequent decorative materials such as paint and wallpaper. Traditional wall grinding operations mostly rely on manual handheld sandpaper or small grinders, which are not only inefficient and labor-intensive, but also difficult to ensure the uniformity of grinding quality. Especially when dealing with special locations such as roof walls or wall corners, workers need to work at heights or adopt unnatural postures, which poses a safety hazard and easily leads to poor grinding effects. In addition, the flying dust generated during the grinding process seriously pollutes the construction environment and endangers the health of workers. Therefore, the development of efficient, safe and environmentally friendly wall grinding devices for construction has become an urgent need in the industry.

[0003] However, in actual use of the existing device, a large amount of debris generated during the grinding process will adhere to the wall surface during the grinding process, and a large amount of dust will be generated during the grinding construction, which can easily affect the workers on site. Therefore, a wall grinding device for construction and a method of using the same are proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that a large amount of debris generated during the grinding process will adhere to the wall surface during the grinding process, and a large amount of dust will be generated during the grinding construction, which can easily affect the workers on site. A wall grinding device for construction and a method of use thereof are proposed.

[0007] When polishing the wall surface, the third motor is started to drive the hollow rotating rod to rotate. The rotation of the hollow rotating rod drives the grinding disc to rotate to polish the wall surface. While the hollow rotating rod is rotating, it drives the second gear to rotate. The rotation of the second gear drives the first turbine to rotate. The rotation of the first turbine absorbs external air and sends it into the interior of the hollow rotating rod. Thus, when the grinding disc polishes, the debris attached to the wall is removed by blowing air inside. The rotation of the hollow rotating rod can also drive the third gear to rotate. The rotation of the third gear drives the second turbine to rotate, thereby absorbing the dust generated during the grinding process of the grinding disc. A handle is provided on the upper part of the vehicle body, and the vehicle body can be easily pushed through the handle.

[0008] The above technical solution further includes:

[0009] An air inlet is provided on the upper part of the control housing, and a dust suction housing is fixedly connected to the front end of the control housing.

A connecting head is fixedly connected to the upper part of the rotating shaft, and a control housing is fixedly connected to the upper part of the connecting head.

[0016] A method for using a wall surface leveling device for building construction includes the following steps:

[0017] Step 1: The personnel push the vehicle body to move the entire device to a position near the wall to be polished;

[0018] Step 2: Adjust the position of the grinding disc through the three-axis adjustment mechanism so that the grinding disc can closely adhere to the wall;

[0019] Step 3: Start the third motor inside the control housing. Drive the hollow rotating rod to rotate through the third motor, and the rotation of the hollow rotating rod drives the grinding disc to rotate to polish the wall;

[0020] Step 4: While the hollow rotating rod is rotating, the second gear and the third gear fixedly connected to the hollow rotating rod rotate synchronously. Drive the first turbine to rotate through the rotation of the second gear, and the first turbine rotates to absorb the external housing and send it into the hollow rotating rod, so that when the grinding disc polishes, the internal air supply blows away the debris attached to the wall. Drive the second turbine to rotate through the rotation of the third gear, thereby absorbing a large amount of dust generated when the grinding disc polishes.

[0021] The present invention has the following beneficial effects:

[0022] 1. In the present invention, by starting the third motor, the hollow rotating rod can be driven to rotate, thereby driving the grinding disc to rotate to polish the wall. While the hollow rotating rod is rotating, it can drive the second gear to rotate. Drive the first turbine to rotate through the rotation of the second gear, so that external air can be sent into the hollow rotating rod through the air inlet, so that when the grinding disc polishes, the internal air supply blows off the grinding debris attached to the polished wall, ensuring that the wall always remains flat during the grinding process. Moreover, the rotation of the hollow rotating rod can also drive the third gear to rotate. Drive the second turbine to rotate through the rotation of the third gear.

The transmission belt 21 is drivingly connected to a fourth gear 22. The fourth gear 22 is fixedly connected to a dust suction housing 3. A second turbine 23 is fixedly connected to one side of the fourth gear 22 away from the dust suction housing 3. A grinding disc 2 is fixedly connected to the front end of the hollow rotating rod 19. A connecting pipe 4 is fixedly connected to the upper part of the dust suction housing 3. A dust collection tank 5 is fixedly connected to the lower part of the connecting pipe 4.
