Technical Field

[0001] The utility model relates to the technical field of building grinding equipment, in particular to a grinding device for building walls. Background Technique

[0002] The grinding device for building walls is a professional tool used for grinding walls during building construction to improve the flatness of the walls and make them smoother. It can greatly improve work efficiency, reduce the manual burden, and ensure the grinding quality.

[0003] Existing building walls mainly include brick walls, stone walls, concrete walls, metal walls, glass walls, etc. When constructing a concrete wall, it is necessary to build a wall formwork. The wall formwork is of a splicing type and is formed by splicing multiple formwork pieces together. However, there will be splicing gaps between the formwork pieces. After the concrete wall is poured, protrusions will appear at the splicing gaps, which need to be ground flat for subsequent construction. However, the existing grinding devices for building walls cannot automatically maintain parallelism, and may damage the flat wall surface when grinding the protrusions. For this reason, we propose a grinding device for building walls. Content of the Utility Model

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1-6 , the present invention provides a technical solution: a grinding device for building walls, including a hood 1. The upper surface of the hood 1 is equipped with a motor 2, which has a rotating function and drives the grinding disc 3 to rotate when rotating to grind the wall surface. The output shaft of the motor 2 is equipped with the grinding disc 3, and the grinding disc 3 is located inside the hood 1. The outer surface of the hood 1 is connected with a discharge pipe 14, and the discharge pipe 14 is communicated with the inside of the hood 1. The discharge pipe 14 can discharge the debris ground by the grinding disc 3 to the outside. The hood 1 can collect the dust ground off by the grinding disc 3 and then discharge it to the outside through the discharge pipe 14. A dust collector can be connected to the outlet position of the discharge pipe 14 to collect the ground dust, so as to reduce the harm of the dust generated during the grinding process to the environment and human health.

[0024] The outer surface of the hood 1 is connected with a support plate 4. Above the support plate 4, a plurality of slide seats 5 are connected. The number of slide seats 5 is four. Correspondingly, both the support bases 6 and the slide seats 5 are four. At the same time, they are located outside the grinding disc 3 and are respectively located at the four corners of the support plate 4. The inner walls of the plurality of slide seats 5 are all slidably connected with support bases 6. The inner sides of the support bases 6 are rotatably connected with runners 7. The inner sides of the slide seats 5 are rotatably connected with lead screws 15. The threaded sections of the lead screws 15 are threadedly connected with the inner sides of the support bases 6. By rotating the lead screws 15, the support bases 6 are pushed to move positions. When the support bases 6 move positions, the runners 7 are driven to move positions. By moving the support bases 6, the runners 7 are pushed to move positions to control the distance between the grinding disc 3 and the wall surface. The runners 7 support the grinding disc 3 outside the protrusion to keep the grinding disc 3 in a parallel plane when contacting the wall surface. The support of the runners 7 facilitates the movement of the grinding device for building walls. An adjusting mechanism 8 is arranged above the slide seats 5.

[0025] When the grinding device is used to grind the building wall surface, vibration will occur, causing the lead screw 15 to rotate on its own. This will cause the support base 6 to drive the runner 7 to move, resulting in the loss of the originally set grinding depth. The adjustment mechanism 8 includes a sliding cylinder 801. The lower surface of the sliding cylinder 801 is connected to the upper surface of the sliding seat 5. A sliding sleeve 802 is slidably connected to the inner wall of the sliding cylinder 801. The sliding cylinder 801 enables the sliding sleeve 802 to have the function of sliding up and down and maintains the stability of the sliding sleeve 802 during sliding. A spring 803 is connected to the inner bottom wall of the sliding cylinder 801, and the other end of the spring 803 is connected to the inner bottom wall of the sliding sleeve 802. After the sliding sleeve 802 slides into the sliding cylinder 801, the spring 803 is compressed. The compressed spring 803 provides a thrust for the sliding sleeve 802 to slide outwards. A chute 807 is opened on the inner side of the sliding cylinder 801. A slider 806 is connected to the outer surface of the sliding sleeve 802, and the outer surface of the slider 806 is in sliding contact with the inner wall of the chute 807. By pulling the slider 806, the sliding sleeve 802 can be driven to move. The chute 807 can guide the moving direction of the slider 806 and restrict the rotation of the slider 806. The slider 806 restricts the rotation of the sliding cylinder 801. One end of the sliding sleeve 802 located outside the sliding cylinder 801 is connected to a first chuck 804. A second chuck 805 is in contact with the outer surface of the first chuck 804. The first chuck 804 and the second chuck 805 are in misaligned contact and restrict each other's moving positions at the same time. When the sliding sleeve 802 slides into the sliding cylinder 801, it drives the first chuck 804 to move at the same time. The first chuck 804 and the second chuck 805 are separated from each other, releasing the positioning restriction on the lead screw 15. The inner wall of the second chuck 805 is connected to a lead screw 15. The threaded section of the lead screw 15 is threadedly connected to the inner side of the support base 6. The outer surface of the lead screw 15 is rotatably connected to the inner side of the sliding seat 5. When the lead screw 15 rotates, it can push the support base 6 to move.

[0026] The upper surface of the machine cover 1 is connected to a base 9. A clamping jaw 10 is rotatably connected to the inner side of the base 9. One end of the clamping jaw 10 is connected to a handle 11. The clamping jaw 10 has an angle adjustment function through the base 9. By using the handle 11, the operating length is increased, which is convenient for construction workers to grind higher wall surfaces. An ear plate 12 is connected to the outer side of the clamping jaw 10. Pulling springs 13 are connected to both sides of the ear plate 12, and the other ends of the two pulling springs 13 are both connected to the upper surface of the machine cover 1. When grinding higher or lower positions of the wall surface, it is necessary to adjust the angle between the handle 11 and the machine cover 1 to facilitate the operation of the construction workers on the grinding device. After grinding is completed, the elastic pulling of the pulling spring 13 can drive the machine cover 1 to reset.

[0027] When the grinding device for the building wall is in use, first adjust the contact distance between the grinding disc 3 and the wall. When adjusting, first pull the slider 806 downward. The slider 806 drives the sliding sleeve 802 to slide into the sliding cylinder 801. The sliding cylinder 801 drives the first chuck 804 to disengage from the second chuck 805. When the sliding sleeve 802 slides into the sliding cylinder 801, the spring 803 is compressed. Then rotate the screw rod 15 to push the support base 6 to move. The support base 6 drives the runner 7 to move. The runner 7 supports the distance between the grinding disc 3 and the wall, so that the grinding disc 3 and the wall generate the size to be ground. Then start the motor 2 to drive the grinding disc 3 to grind the wall, and control the moving position of the grinding device for the building wall through the handle 11.
